Definitions
- the invention relates to a heat-insulating profile body, in particular for use in door or window frames or the like, consisting of two profile rails, preferably those made of metal, which are connected to one another by two profiled insulating webs made of heat-insulating material, the insulating webs being made from a supporting web and engage undercut grooves of the profiled rails formed in a retaining web.
- the invention further relates to a method for producing this heat-insulating profile body and a tool for carrying out this method.
- Such heat-insulating profile bodies are known. With them, the insulating bars serve to rigidly connect the two rails. Various methods are now known with which this connection can be brought about.
- So z. B. known to dimension the insulating webs so that they can be inserted with all-round play in the undercut grooves of the rails.
- the insulating webs are then attached in that the cavity which the .insolating webs and the profile rails enclose are filled with a foam which expands on solidification. Due to this expansion, the insulating webs and the profile rails are firmly pressed together in their fitting position. At the points where the profile rails and the insulating webs meet, there is a very strong frictional connection, which prevents mutual displacement.
- the foam can also serve as an adhesive.
- the profile bodies produced by this process have good properties, but their manufacture requires high investment costs. Furthermore, in certain cases, such profile bodies cannot be used with regard to the flammability of the foam.
- the object of the invention is to provide a heat-insulating profile body which can be produced with simple means and which has a very firm and permanent connection between the insulating webs and the profile rails, so that the frictional engagement between the insulating webs and the profile rails is also stable over a long period of time and thus the profile body remains rigid.
- individual deformations which protrude into the groove and which abut the insulating web, are arranged at a distance from one another on the support webs, optionally also the holding webs of the undercut grooves. If the deformations are more pronounced, they can also penetrate the insulating web. If, as is preferably provided, the supporting web is deformed, the insulating web is pressed against the end face of the holding web of the groove and thus a permanent contact pressure is exerted.
- the insulating web can be pressed not only against the end face of the above-mentioned retaining web, but also as a fixed system of the insulating web on a further inner surface of the holding web. This is done, for example, in such a way that when producing the individual deformations, the profiled rails are pressed apart or pulled so that the legs of the insulating webs are pressed firmly against those stop surfaces of the holding webs which are perpendicular to their end faces.
- the insulating web is provided with longitudinal grooves on its surface facing the holding web.
- the grooves of the insulating web prevent displacement relative to the holding web, so that the contact pressure against the abovementioned stop surfaces is maintained as a result.
- the same result is achieved if the grooves are not attached to the insulating web but, according to another embodiment of the invention, to the corresponding surface of the supporting web.
- an even stronger contact pressure can be achieved according to a further embodiment of the invention in that the insulating web is provided with trapezoidal (conical) legs that taper outwards. If these insulating webs are used with their legs in the undercut part of the groove and pressed against the holding web with the deformations of the supporting web, then a full contact of the insulating web in the undercut part of the groove is achieved due to the wedge effect associated with the trapezoidal shape. The same result can also be achieved in that the undercut part of the groove itself has a trapezoidal shape. Likewise, both the leg of the insulating web and the undercut part of the groove can have a trapezoidal shape.
- the deformations are only applied individually and at intervals to the support web, they can protrude so far that the insulation web is also deformed at the relevant points. If this is the case, the profile rails can never move against each other in the longitudinal direction. The deformation of the support web can also go so far that the support web shears from its base in the deformation region. The same applies if the deformations are not applied to the supporting webs but to the L-shaped holding webs.
- Such deformations are preferably produced with tools, the tip of which has the shape of a triangular or polygonal prism, a prism surface running parallel to the inner surface of the profile rails or the groove base surface.
- This embodiment brings about a permanent connection or clamping between the insulating webs and the profile rails.
- the bending edge between the undeformed part and the notched part of the respective support web can run parallel to the longitudinal axis of the profile body.
- Another embodiment provides that the bending edge runs perpendicular to the inner surfaces of the profile rails or to the base of the groove. If the deformations are then additionally designed such that the bending direction of the notched parts alternates, this results in an advantageous pawl effect in relation to the longitudinal stroke in both directions of the longitudinal axis of the profile body.
- a further embodiment provides that the deformations are achieved with tools, the tips of which have the shape of a triangular or polygonal pyramid, the base of the pyramid running parallel to the inner surface of the profile rails or of the base of the groove.
- the deformations can be configured so that the inclination of the bending edge is of the notched parts against the profile body axis less than 9 0 °, and the inclination direction between Benach beard deformations alternate, so that an advantageous pawl effect is achieved in this embodiment.
- Deformations on two mutually opposite supporting webs (or holding webs) are essentially the same. This ensures that any tilting forces that occur on one insulating web are compensated for by corresponding tilting forces that act on the other insulating web. This prevents unilaterally occurring tensions in the profile body and prevents it from warping.
- a sufficiently rigid profile body is created when the permanent deformations in the support web are sufficiently strong. Such sufficiently strong deformations can, however, be provided in the support web if the insulating strips have sufficient play in the grooves or if the deformations can be pressed or pressed into the material of the insulating strips.
- insulating strips which are made of hard material that resists deformation.
- a hard material can be hard paper, for example, which is characterized by high heat resistance.
- the profile body of the type described at the outset is designed such that the profile body is a sufficiently rigid structure even when there is a high degree of fit between the profile rails and the insulating strips and / or when using insulating strips made of hard material.
- each Insulating strip has a continuously rounded or beveled edge area directed against the projecting deformations, against which the deformations rest.
- the desired pressure on the edge area can also be achieved by deforming a web which does not abut the insulating strip before deformation, the deformation of this web being such that the end face thereof is in contact with the edge area.
- a part is worked out in the section of the profile rail opposite the edge area of the insulating strip, which part is pressed against the edge area like a plow to form the deformation.
- This deformation can also be carried out continuously or in sections.
- the part can be pressed against the edge region of the insulating strip, in particular if it has already been formed during the manufacture of the profile rail, by means of a wedge that starts up.
- the part can be made in the manner of a plow with the insulating strip already inserted from the insulating rail in one operation and pressed against the edge area.
- the surfaces of the web or of the part facing the edge region can be provided with transverse corrugations, which bear against the insulating strip and, if necessary, press in, as a result of which the shear strength of this composite arrangement is increased.
- the insulating strip is pressed into the L-angle by the deformations.
- the support webs lie firmly against the insulating webs over their entire length in the region of their end faces.
- the abutment of the upper part of the support webs brings about a further strength.
- a sealing or adhesive mass is located in the space between the insulating web and the inner surfaces of the undercut grooves.
- This mass can be permanently elastic or solidified. It seals the longitudinal joints, which in any case leads to additional anchoring of the insulating web when an adhesive is selected.
- a material that softens at elevated temperature is particularly suitable for the manufacturing process.
- ribs are attached in the inner surfaces of the profile rails in the longitudinal direction, the wall thickness of which is at least the same, preferably greater than the wall thickness of the support webs.
- this profile body is preferably first loosely assembled from profile rails and insulating webs. The deformations are then applied inside the cavity, which is enclosed by the profile rails and the insulating webs, on the support webs, and possibly also on the holding webs. In principle, however, it is also possible to apply deformations not from the cavity but from the outside if the grooves are arranged in a corresponding manner on the profile rails.
- the deformations can be produced one after the other. However, it is advisable to simultaneously impress mutually opposing deformations on the support webs so that the forces exerted by the deformation tool on the profile body cancel each other out and no torsion or twisting of the hollow profile can occur.
- the profiled rails are clamped apart from one another before the deformation is impressed, so that the insulating webs lie firmly against the stop faces of the undercut grooves. If, in this state, the deformations are hammered in at the base of the supporting webs with a wedge or a mandrel, then insulating webs receive a pressing force against the stop surfaces, so that the insulating webs remain firmly in contact with these stop surfaces.
- the profile rails are stretched so far apart that the legs of the insulating webs open elastically. After applying the deformation and relaxing the profile rails, the elastic forces of the insulating webs then contribute to the fact that their legs lie snugly against the stop faces of the undercut groove.
- an expansion block is preferably used which is cushioned and which pushes the profiled rails apart, so that the legs of the insulating webs abut the abutment surfaces of the grooves and, if necessary, open elastically if the springs of the expansion block are correspondingly strong.
- Arms are attached to the expansion block, which are provided with bulges. These arms are driven apart with a spreading wedge so that the bulges of the arms hit the support webs and cause the deformations there.
- An expansion block with four attached arms is preferably used as the deformation tool, so that each time the expansion wedge is actuated, four deformations are achieved simultaneously.
- the deformations in the support webs are preferably stamped in such a way that their flank lying at the base of the support web is flush with the inner surface of the profile rail. In this case, no damage to the profile rails can occur during the formation of the deformations.
- the expansion wedge and the articulated arms are designed so that the forces occurring when driving in the expansion wedge are directed essentially against the support webs and only a small force component acts on the inner surfaces of the profile rails.
- this small force component in the direction of the profile rails it is achieved that the bulges of the articulated arms which cause the deformations attack the base of the support webs, on the other hand this force component is so small that damage to the profile rails cannot be concerned.
- a conical expansion wedge provided with a toothing, in particular with a screw thread, is screwed into a correspondingly designed toothing at the end of the articulated arms.
- the deformation tool is pushed forward on a support rod step by step through the cavity of the loosely preassembled profile body and spread with each step.
- the length of the support rod should be at least equal to the length of the profile body to be manufactured. Accordingly, it may be expedient to advance the deformation tool from both ends of the profile body only to the middle.
- the deformation tool has an expansion block, a high frictional resistance must be overcome when the deformation tool is pushed in and out into the cavity. Accordingly, according to a further embodiment of the method according to the invention, it may be advantageous to first provide the lower profile rail with the insulating webs in order to produce the profile body, then to insert the deformation tool in such a way that its support rod is in the "groove” formed by the lower profile rail and the insulating webs. lies, the actual deformation tool (spreading block with arms) protrudes beyond this "groove”. Then the upper profile rail is pushed with its grooves over the insulating bars, so that a loosely pre-assembled profile body arises.
- the profile body is then pushed over the deformation tool, this deformation tool gradually producing deformations on the support webs.
- the mutual distance between the individual deformations can advantageously be determined by the speed at which the profile body is moved against the deformation tool and by the frequency with which the deformation tool is actuated.
- the applicator has an outlet nozzle which is open towards the intermediate space in the working position.
- the nozzle is sealed off from the cavity of the profile body, so that the sealing compound or adhesive compound is only pressed into the space between the insulating web and the inner wall of the groove.
- the application device can, for example, be inserted into the preassembled profile body and driven through it. Due to the pressure of the flowable mass, the insulating webs are pressed against the stop faces and the end faces of the undercut grooves, so that a tight seal is achieved there.
- a solid or pasty strip from the mass can first be applied to the inside of the insulating webs and then z.
- a scraper plate or a roller that seals on the inner surfaces of the rails or the surfaces of the supporting webs abut and is passed longitudinally through the cavity of the preassembled profile body, pressed into the intermediate space.
- the pasty strip can also be applied to the insulating webs before the loose pre-assembly of the profile body, so that it is possible, for. B. use a powerful glue coating system.
- the applied mass must be so firm that it survives the pre-assembly of the profile body. It is therefore advisable, according to an embodiment of the associated method according to the invention, to use a mass which can be softened by increasing the temperature, e.g. B. a hot melt adhesive.
- a displacement tool z. B. a roller used, which is itself heated and with which the applied mass is softened.
- This displacement tool can be integrated with the deformation tool, e.g. B. in the form of a corresponding projection on the block of the deformation tool carrying the spreading arms or in the form of a projection on an expansion profile which is pulled through the cavity of the profile body for the formation of the deformations.
- the present invention specifies a production method in which the deformation of the support webs is achieved with the aid of two deformation rails, these deformation rails being inserted into a loosely preassembled profile body and then being pressed apart with the aid of an expanding wedge. As a result, the deformation rails are squeezed against the supporting webs and this is thereby pressed against the insulating webs.
- This method can not only be used to produce such profile bodies in which the support webs are provided with individual, spaced-apart deformations, but it can also be advantageous for use the production of profile bodies according to the prior art, in which the support webs are bent or bent against the insulating webs.
- the deformation rails can consist of two metal strips, the width of which is dimensioned such that they rest on the inner surfaces of the support webs lying towards the cavity.
- the ligaments and with them the support webs are then bent outwards.
- these two deformation rails are connected at their front end by an elastic or articulated bridge.
- This bridge is kept so flat that it fits into the space between the two supporting webs.
- This articulated bridge serves on the one hand as an aid for inserting the deformation rails into the cavity of the preassembled profile body, on the other hand it holds the deformation rails together between the individual operations, so that the package formed from the deformation rails and the pull rod located between them is simply guided can be.
- the deformation rails have corresponding bulges.
- the deformation rails are inserted in such a way that these bulges abut the support webs.
- These bulges of the deformation rails can, for example, be continuous ribs which are attached transversely to the longitudinal direction of the deformation rails.
- the cross section of these ribs can in turn be of any shape, for example triangular, trapezoidal or semicircular: if the deformations are achieved essentially in the area of the base of the respective support web, the bulges protrude further at the edges of the deformation rails than in the middle thereof.
- these bulges can then be designed as individual teeth, but transitional forms between the rib-shaped configuration and the individual teeth are also possible, in that such a rib, for example, protrudes further on the edges of the deformation rails than in the middle thereof.
- these teeth can have the shape of a triangular or polygonal pyramid or a triangular or polygonal course dimension or also a truncated cone.
- deformation rails can advantageously be used for this purpose, which are bevelled on the edges lying to the support webs. If only a beveling of the support webs is desired, this bevel is continuous over the entire length. If, in addition to the folding, the application of individual deformations in the base area of the support webs is desired, these are bevels interrupted by the bulges arranged at a distance. These bulges can run up to the edge area of the deformation rails, but they can also end a small distance in front of it.
- the deformations will not protrude furthest in the base region of the support webs, but in an area closer to the end face of the support webs.
- the deformation rails and the expanding wedge are expediently designed such that they can be inserted together as a package into the cavity of the profile body.
- the deformation rails have recesses in which the expansion wedge lies when it is inserted, so that the entire arrangement fits into the cavity.
- a tie rod is attached to a corresponding holder of the deformation rails.
- the deformation rails may have holes at their ends projecting beyond the profile body, into which, before the beginning of the expansion process, for example, bolts suspended from an abutment are inserted, for example with the aid of a compressed air cylinder.
- the insertion of these bolts can also be done in such a way that the ends of the Verfor provided with the holes due to the expansion process tion rails are pressed outwards and thereby engage in corresponding abutments.
- This sequence of movements can be controlled very easily automatically, so that this production sequence can still be designed very efficiently.
- This invention also proposes several types of deformation tools which are advantageously used in the production of the heat-insulating profile body.
- such a deformation tool consists of a block on which arms provided with bulges or thorns are attached.
- this block with the attached arms is inserted into the cavity formed by the profile rails and the insulating webs, and the arms are pressed apart with a spreading wedge, so that the bulges or the mandrels are applied press the desired deformations into the support webs.
- the shape of the block is designed so that it fits fairly precisely in the cavity of the loosely mounted profile. It is more expedient, however, if this block is designed as an expansion block, so that it presses the two profile rails apart with spring action, since manufacturing tolerances can then be compensated for with such a tool.
- Return springs are attached to the arms of the deformation tool, so that each actuation of the expansion wedge releases the mandrels of these arms from the deformations generated and the arms return to their starting position.
- a support rod is attached to the block so that the deformation tool can be pushed or pulled through the hollow profile.
- a push rod is also attached to the expanding wedge, on which, for example, an eccentric engages, so that the arms of the deformation tool are pressed apart at a frequency corresponding to the rotational speed of the eccentric.
- die'Trägerstange is formed as a tube and that "is passed through the push rod, to the expanding wedge actuated through this tube and through the tube attached to the block.
- This configuration allows a loosely preassembled profile body to be automatically pushed onto the deformation tool, for example with a conveyor belt.
- the support rod serves on the one hand to push the deformation tool through the loosely mounted profile body. It also has the function, when actuating the expanding wedge, of absorbing the thrust effect which the expanding wedge exerts on the entire deformation tool and thus preventing the deformation tool from slipping or shifting during this expansion process. According to a further advantageous embodiment of the deformation tool according to the invention, it is also possible, however, to do without such a support rod by using the profile itself as an abutment.
- the push rod attached to the expansion wedge is held by a spring on the expansion block and is pressed by this spring against the arms, so that the bulges or mandrel tips attached to these arms bite into the profile; this prevents displacement of the deformation tool against the profile rails when the expansion wedge is actuated. If the expanding wedge is then pulled out of the arms again, a stop on the push rod ensures that it does not slip out of the guide of the block.
- a further advantageous embodiment of the deformation tool used according to the invention takes into account the fact that the profile bodies in production have the most varied shape and thus also the most varied cavity cross sections. Since the deformation tool must be adapted to this cavity cross section, it is desirable to be able to remove the parts causing the deformation from the support rod and the push rod. This is made possible by the push rod being attached to the block in one brought coupling member ends and that on this coupling member, the support rod and an extension rod for the push rod are removably attached.
- the coupling member is, for example, a screw lock or a quick lock known per se (for example a bayonet lock or a bayonet lock).
- the deformation tool has four arms which are provided with bevels in such a way that a recess with a diamond-shaped cross section is formed between them. If a diamond-shaped expansion wedge is then driven into this recess, the articulated arms are pressed both against the inner surfaces of the profile rails and against the supporting webs. Appropriate choice of the diamond-shaped cross section ensures that the contact pressure against the inner surfaces of the profile rails is smaller than the pressure directed outwards against the support webs.
- the diamond lies with its longer diagonal in the direction of the pivot axes of the arms.
- the wedge action is directed primarily outwards against the support webs and, with a smaller thickness, against the inner surfaces of the profile rails.
- Another embodiment of this deformation tool provides that the articulated arms are provided with springs or are themselves designed to be resilient, so that they rest on the inner surfaces of the profile rails due to the spring action.
- the expanding wedge ko nisch trained and is provided with a helical toothing, and that a matching toothing is attached to the arms. The arms are then spread in such a way that the cone of the expanding wedge is screwed into the toothing on the arms, whereby these arms open and produce the desired deformations.
- Another deformation tool which is also used with good results, consists of a cuboid block which has slots on its longitudinal edges, in which pins are movably inserted. These pins end with their heads in corresponding recesses of a push rod which is guided through it, centered on the longitudinal axis of this block. Depending on the position of the push rod, the tips of these pins extend beyond the contour of the block or recede behind this contour. In a reciprocating movement of the S chubstabes thus jumping for these peaks and back, so that the desired deformations are caused in this way.
- Another deformation tool has, as the deformation-causing elements, disc wheels which are provided with individual spikes on their circumference. When these disc wheels roll along the support webs, the mandrels press into these support webs and cause the desired deformations.
- This deformation tool consists in particular of two pairs of disc wheels, a gear wheel being arranged between each such pair. These gears mesh with each other.
- the disc wheels are also provided with recesses V adapted to the mandrels, so that when the disc wheels rotate against one another, the spikes of one disc wheel engage in the recesses of the other disc wheel, so that these disc wheels can rotate against one another without mutual interference.
- the disc wheels are pressed apart with the aid of a spring device.
- a push rod which is preferably attached to the shaft bearings of the pairs of wheels, this deformation tool is guided through the cavity of the profile body.
- a modification of this embodiment provides that two pairs of disc wheels are mounted on a drawing slide which runs between the wheels of a pair, the disc wheels being provided with continuous bulges instead of thorns. These bulges can taper towards the outside of the disc wheels, so that they can be used to fold the support web.
- a further modification provides that the disk wheels are provided with a toothing in the area which lies above the support web, that is to say on their inner side facing the drawing slide.
- the toothing of two disk wheels are in engagement with one another so that the rotary movement of the disk wheels of the different pairs is coupled to one another.
- the gears thus replace the gears described above. If the disk wheels of each pair are each rigidly mounted on an axle, the toothing need only be present on one of the two disk wheels.
- the teeth can be designed such that some of the teeth continue as bulges over the circumferential surface.
- the disc wheels are preferably mounted offset to one another in the drawing slide. In extreme cases, the diameter of the disc wheel can be almost as large as the clear width of the profile cavity.
- guide rollers are provided, which can be located in front of or behind the disc wheels. You can support yourself on the support bars or on the insulating bars when pulling through the slide.
- the links are formed by swivel arms articulated on a block, on the end of which the teeth are formed opposite the articulation, the block being guided in the longitudinal direction of the cavity in such a way that the push rod of the expansion wedge is also guided in the longitudinal direction of the cavity and can be moved back and forth, and that the return device is formed by an ejector which can be moved with the expansion wedge and is guided outside the swivel arms so that when the expansion wedge is moved in one direction, the formation of the Deformations of the ejector is disengaged from the swivel arms and that when the swivel arms are released by moving the expansion wedge in the opposite direction, the ejector releases its teeth from the deformation by contacting the swivel arms.
- the pushrod driven via an eccentric drive is guided in a guide tube which is connected to the block for longitudinal movement thereof, whereby longitudinal forces in the pushrod and longitudinal forces in the guide tube essentially cancel each other out, which is essential in the case of long profile bodies.
- the guide tube can be guided between two end stops, the distance between which determines the distance between the deformations to be formed, and when the profile body is moved in only one direction, for example by means of pinch rollers with a backstop, the shaping tool according to the invention simultaneously causes the profile body to be transported becomes.
- the ejector is advantageously designed so that it is moved with the expanding wedge and, when the expanding wedge is moved away from the swivel arms, the swivel arms are released from the deformations formed in that part of the ejector is inserted between the insulating web and the swivel arm.
- connection between the guide tube and block and preferably also between the push rod and the expanding wedge is designed to be detachable, for example by means of a pin connection.
- the shaping tool consists of two shaping rails and an expanding wedge, which are dimensioned such that the expanding wedge in the longitudinal direction between the shaping rails through the cavity of the pre-assembled Profile body can be carried out while achieving a contact pressure directed against the support webs.
- the deformation rails preferably consist of a harder material than the expansion wedge. This measure is particularly recommended when the deformation rails are provided with individual bulges or teeth according to a further embodiment of the invention, since in this case it is easier to To replace expanding wedge as new deformation rails.
- the deformation rails have corresponding bulges.
- the support webs be folded against the insulating webs during the deformation, this can be achieved by means of deformation rails which have bevels on their edges. Furthermore, it is possible to provide a combination of bevels and bulges, so that the support webs are both folded and provided with individual, spaced-apart deformations when the deformation rails are driven apart.
- the deformation rails are provided with lugs which protrude into the cavity.
- the expansion wedge has corresponding guide grooves, into which these lugs of the deformation rails engage.
- the lugs of the deformation rails thus serve as a guide for the expanding wedge.
- the deformation rail NEN are provided with longitudinally extending projections, each of which engage in the space between the support webs. In this way, the mutual position of the deformation tool and the loosely preassembled profile body or its parts is better fixed.
- the deformation rails can be designed as individual flat strips or as flat profiles.
- the deformation rails have a U-shaped cross section, which are dimensioned such that one deformation rail fits into the other deformation rail. With this measure, a precisely rectangular cross-sectional shape and thus a symmetrical failure of the profile body produced can also be achieved.
- the expansion wedge is pulled through in the space that is enclosed by the two U-shaped deformation rails.
- the two deformation rails with an identical, U-shaped cross-sectional profile.
- a mutual fixation of the deformation rails is advantageously achieved in such an embodiment in that the free legs of the deformation rails are provided with interlocking teeth. In this way it is avoided that when the expansion wedge is pulled through, the deformation rails move relative to one another in the longitudinal direction.
- the deformation rails are equipped with a holder for receiving a tie rod.
- This holder can in particular consist of two bores which are provided on the free ends of the deformation rails which protrude beyond the preassembled profile body.
- a tie rod can be used as a tie rod ter bolt are used, which is inserted into these holes before pulling the expansion wedge.
- the deformation rails together with the expanding wedge and the tie rod attached to it are inserted through the cavity of the profile body, it can be provided according to another embodiment of the invention that the expanding wedge is removably attached to the tie rod.
- the tie rod has a flat cross section.
- a further embodiment of these deformation tools provides that the deformation rails are connected to one another at their ends with a flat, elastic or articulated bridge in order to facilitate the introduction of this deformation tool and its further handling in the manufacturing process.
- An alternative embodiment provides that a right and a left wedge-shaped ejector part, for. B. in the direction of movement behind the expanding wedge, between the tape and insulating web.
- a deformation device for the profile body of the type mentioned with one according to the invention is characterized by a conveyor for the longitudinal conveyance of the profile body before, during and after the shaping of the deformations and by a drive to guide at least the expansion wedge and the ejector in the cavity of the profile body.
- the conveyor can be formed both by a belt conveyor and by a roller conveyor.
- its drive preferably acts on a plurality of rollers via a chain hoist. If the deformation tool is designed so that it effects a step promotion of the profile body, the rotational force of the rotary drive of the conveyor is such that it alone is just not sufficient to convey the profile body.
- a longitudinal conveyance in only one direction of the profile body can take place, as mentioned, by means of pinch rollers with a backstop, which act on both sides of the profile body.
- the beginning and the end of the profile body can be detected by means of limit switches and, depending on this, the shaping tool and / or the conveying device can be started or stopped.
- FIG. 1 schematically shows a heat-insulating profile body according to the present invention.
- a profile body consists of two profile rails 2, in particular a lower profile rail 21 and an upper profile rail 22.
- These profile rails have undercut grooves which are formed from a support web 4 and an L-shaped holding web 5.
- Insulating webs 3 ′ engage in these grooves.
- These support bars are provided with deformations against the Press insulating bars. These deformations are cylindrical in the example shown in FIG. 1.
- the insulating webs are also provided with longitudinal grooves 35 so that they cannot slip against the supporting webs. This is illustrated in more detail in Fig. 2. Due to the deformations 7, the insulating web is pressed against the end faces 55 of the L-shaped holding webs 5.
- the insulating web rests with its legs 33 and 34 on the stop surfaces 54 of the holding webs 5. So that this fixed system does not come loose, the grooves lying on the supporting web 4 are attached to the insulating web. It is also possible to provide these grooves on the support web. In this case, the grooves of the support web press into the material of the insulating web in the region of the deformations and thus determine its position. As can be seen from FIGS. 1 and 2, the cylindrical deformations 7 are pressed in parallel to the inner surface 23 of the profile rail 2. They thus extend to the base 47 of the support web 4.
- the insulating web 3 Whenever the insulating web 3 is pressed against the end face 55, it can - at the same time or instead of - also be pressed against the face 53. This depends entirely on the proportions, i.e. H. whether the undercut is deeper in the receiving groove or in the insulating web or whether both undercuts are the same depth. All three options occur.
- Fig. 3 shows a further embodiment for a profile body according to the invention.
- the undercut groove of the profile rail and the leg 33 of the insulating web 3 have a trapezoidal cross section. If the cylinder-like deformations 7 are applied in this embodiment, the leg 33 of the insulating web is pressed into the undercut part of the groove, so that there is a full contact of the insulating web on the stop surface 54, on the end face 55 and on the bottom surface of the groove gives.
- Fig. 4 is a longitudinal section through the support web 4 and illustrates how these deformations 7 pass through the support web, so that the support web presses strongly against the insulating web in the deformation region.
- the deformations 7 are designed so that they are conical and project the furthest at the base of the support web 4 or on the inner surface 23 of the profile rail.
- the insulating web receives a pressing force in the direction of the stop surface 54 and the end surface 55, so that there is a full contact of the insulating web.
- the conical deformations 7 can be produced, for example, with a sharp-edged, cone-like tool which is placed on the inner surface 23 of the profile rail 2 and is struck laterally against the support web 4.
- FIGS. 41 to 50 Further embodiments are shown in FIGS. 41 to 50.
- Fig. 41 with the help of a tool 14o, the roof edge-shaped teeth 142, individual tab-shaped parts 41 are deflected from the support webs 4 so that the bending edge 42, which runs between the undeformed part 4o and the notched part 41, parallel to the longitudinal axis of the Profile body runs.
- 42 to 44 show further modifications in which the deformations are generated with pyramidal teeth 142, and the corresponding tools 14o.
- 46 to 48 show further embodiments in which the bending edge 42 extends perpendicular to the inner surfaces of the profiles, as well as the corresponding deformation tools 14o, which are provided with prism-shaped teeth 142.
- FIG. 49 shows a modification of the embodiment according to FIG. 45, in which the bending device of the notched parts alternates. This leads to a desired pawl effect.
- the deformation tool 14o has appropriately designed teeth 142 which alternate in shape.
- 5o also shows an embodiment with a pawl effect.
- the deformations of pyramid-shaped teeth 142 of the tool 14o are generated, so that the notched parts 41 have a bending edge 42 with respect to undeformed parts 4o of the support web 4, which is inclined relative to the inner surface 23 of the profile rails 2.
- the direction of inclination with respect to the longitudinal axis of the profile body alternates.
- FIG. 7a shows a further embodiment for the application of the deformations, the effect of which corresponds to that of FIG. 5.
- the deformations are driven in with the aid of a mandrel or a roof-like tip on the base 47 of the support web 4, so that these deformations project further at the base than above it.
- the insulating web abuts the abutment surface 54 and the end surface 55 of the L-shaped holding web 5.
- the intermediate space 14 (cf. FIG. 7a) is between rule the insulating webs 3 and the inner walls of the grooves 6 filled with a hot melt adhesive 13, so that increased strength is achieved.
- Fig. 7c the support web 4 is folded over the entire length against the insulating web 3 in the region of its end face 46 and lies firmly against it. This measure also results in an increased hold. It should also be mentioned that also in FIG. 7c the intermediate space 14 can be filled with an adhesive or sealing compound as in FIG. 7b.
- FIG. 9 to 11 illustrate the manufacturing process for a heat-insulating profile body according to the invention.
- a loosely preassembled profile body is assembled from profile rails 2 and insulating webs 3.
- the profile rails 2 are then stretched apart or pressed apart from the interior of the cavity 8, so that the legs 33 and 34 of the insulating webs 3 bend apart elastically (FIG. 9).
- conical or mushroom-shaped deformations are now knocked into the support webs 4 in accordance with FIGS. 5 or 7. Because of these deformations, the insulating web receives a snug fit on the stop faces 54 and the end faces 55 of the undercut grooves, as has already been described with reference to FIGS. 5 and 7.
- the profile rails 2 are relieved of the tensile stress.
- the elasticity of the insulating webs now causes the legs 33 and 34 to lie particularly firmly against the stop surfaces 54.
- insulating strips are made of hard material, it is advantageous if they are made according to the invention forms are how z. B. is shown in Fig. 2.
- the insulating strip 31 shown there on the left is provided with a continuous bevel 18 in the region of the projections 7.
- the insulating strip shown on the right is provided with a continuous rounding 28.
- the projections in the embodiment according to FIG. 2 are formed by tabs 17, which are pressed out at regular intervals from the supporting webs 4 and which are closely and firmly attached to the edge regions of the insulating strips 31, 32, i.e. H. Apply to the bevels 18 or roundings 28.
- the projections in the exemplary embodiment according to FIG. 3 are formed by deforming webs 4. These webs 4 project from the profile rail 22 in such a way that they are not in contact with the insulating strip 31, 32 before the deformation, but that their end face 46 is in close contact with the edge regions 18, 28 after the deformation, in such a way that that a pressure on the insulating strip 31, 32 in the direction of the L-angle of the L-shaped retaining web 5 is exerted.
- a major advantage of the exemplary embodiments according to FIGS. 3 and 4 is that the deformations can be carried out either continuously or in sections. In particular with continuous deformation, it is ensured that high adhesive forces also occur with insulating strips 31, 32 made of hard material.
- the portions of the deformations that come into contact with the edge region 18, 28, ie. H. the end faces 46 of the webs 4 or the surfaces 12 of the parts 11 facing the edge region 18, 28 have transverse corrugations which can also engage in insulating strips 31, 32 made of hard material, which greatly increases the shear strength of the composite arrangement thus achieved.
- the deformation can be carried out in a relatively simple manner, specifically by means of a drawing mandrel or a drawing wheel.
- the tool acts like a plow and, when the part 11 is raised, presses its surface 12 against the edge region 18, 28.
- This tool essentially acts like a wedge when the part 11 only touches the edge regions 18, 28 must be pressed, but has already been manufactured in the manufacture of the rail 1.
- the part can also be cut out at the same time in a single operation, that is to say shaped and raised, that is to say deformed, in which case, however, the connecting surface between the two opposite parts 11 of a profiled rail 1 would not be flat, which is not disadvantageous, however.
- edge areas must be rounded, since in these cases both the end face 46 of the web 4 (FIG. 3) and the face 12 of the part 11 (FIG. 4) abut the rounded edge area 28 can come and can exert the desired pressure towards the L-angle.
- the deformations are applied from the cavity 8 to the support webs of the undercut grooves. In principle, however, it is also possible to apply these deformations in the base region 57 of the holding webs 5. This is shown schematically in FIG. 12. In this embodiment, too, the insulating webs abut against the stop surfaces 54, since the deformations exert a force on the insulating web directed towards the center of the cavity. In this embodiment, however, one no longer obtains an abutment on the end faces 55, but instead on the outer faces 43 of the support webs 4.
- FIG. 13a schematically shows a perspective illustration of such a deformation tool. It consists of a block 91, on the top and bottom of which springs, for example leaf springs 911, are attached. These springs 911 serve to push the rails 2 apart.
- springs 911 serve to push the rails 2 apart.
- arms 92 are also attached to this block 91 and can be pivoted about axes 925 or 926. These arms are provided with bulges or thorns 921.
- These mandrels 921 are designed such that their flank 922 is flush with the outer surface 927 of the respective arm.
- the four arms 92 When driving the mandrel 921 into the support web it is avoided in this way that the inner surface 23 (see FIGS. 1o and 11) of the pro filschienen 2 is injured, the four arms 92 have bevels 929 on their inside. These bevels are designed so that they form a tapering recess with a diamond-shaped cross section. To spread the arms apart, a correspondingly designed expansion wedge 98 is pressed or struck into this diamond-shaped recess by means of a push rod 96. Due to the diamond-shaped shape, the arms then receive a primarily laterally directed force, but also a smaller upward or downward force, which leads to a secure contact of the bulges or mandrels 921 at the base of the support webs to be deformed.
- the arms 92 are also provided with return springs 99. These return springs 99 ensure that the arms 92 are returned to their starting position after each deformation of the support webs. With a corresponding design, these springs 99 can also be used to ensure that the arms are deflected outward in the direction perpendicular to their pivot axis (in the example from FIG. 13a thus upwards or downwards). This deflection also ensures that the mandrels rest securely on the base of the webs.
- FIG. 13b shows a modified embodiment in which the arms 92, on which the bulges 921 are located, are provided with inclined surfaces 924. These inclined surfaces serve to tilt the support webs 4 when the arms 92 are driven apart in such a way that their upper end rests firmly against the insulating webs 3, as is shown in FIG. 7c.
- a support rod 95 is attached to the block 91 so that it can be moved within the cavity of the profile body. 14 shows that the expansion wedge 98 is inserted from the other side with its push rod 96. A preferred arrangement is shown in Fig. 15 represented table.
- the support rod 95 is designed as a tube and the push rod 96 of the expanding wedge 98 runs within this tube and is guided through the block 91. When the push rod 96 moves relative to the support rod 95, the expansion wedge 98 is driven forward and moves the arms 92 apart.
- FIG. 16 shows a further development of the embodiment according to FIG. 15.
- the push rod 96 ends in a coupling member 9o1.
- the support rod 95 is attached to this coupling member.
- the coupling member 9 0 1 is a screw connection in the simplest case, but it is expedient to use a quick-release fastener, for example a bayonet fastener.
- a spring 94 With the help of a spring 94 the push rod is pressed to the right so that the expanding wedge 98 disengages from the pivotable arms 92. So that the push rod 96 does not slip out of the block 91, a stop is provided.
- the push rod 96 is moved to the left against the pressure of the spring 94 with the aid of an extension rod 961, as a result of which the arms 92 are pivoted outwards.
- Fig. 17 shows schematically the case that the expansion wedge 98 is conical and is designed with a screw thread.
- the arms 92 are provided with a corresponding toothing on their inside. By screwing in the helical spreading wedge 98, the arms 92 are pressed apart and the bulges 921 thus cause the deformations in the support webs.
- the arms 92 enclose a diamond-shaped recess. It is also shown that taper pins 928 are inserted in these arms and the tips of these taper pins are used to produce the desired deformations. The taper pins are inserted so that the flank of their tip is flush with the edge 927 of the arms. If the cone angle of the Tip has the size 2 ⁇ , so the axis of the taper pin must be inclined by the angle ⁇ against this edge 927.
- FIG. 19 schematically shows a further deformation tool that does not require the support rod, in which case only a single force introduction element is necessary.
- the push rod 96 is held within the block 91 with a spring 94, by which it is pressed in the direction of the arms 92. If no further forces are thus exerted on the push rod, the expansion wedge 98 acts against the arms 92 and pushes them apart. As a result, the tips 921 of the arms bite on the support webs to be deformed.
- the profile rails are fixed on the work table against longitudinal displacement and thus act as an abutment when the push rod 96 is struck against the arms 92 to form the deformations.
- FIGS. 21 and 22 schematically show another tool with which the desired deformations can be produced inside the profile body.
- This tool consists of a cuboid block loo, in which two concentric longitudinal holes lo4 and 1 0 5 are made.
- slots 102 are cut. These slots are bounded at the top (see FIGS. 21 and 22) by surfaces 106 which run perpendicular to the longitudinal axis 103 of this cuboid. At the bottom, these slots are delimited by inclined surfaces 107, so that these slots open towards the inside of the block.
- Fig. 2o schematically shows a cross section through such a block 1 00th
- FIG. 21 is a section in the direction AB of FIG. 20 .
- FIG. 21 shows the push rod 96 in a lower position, in which the tips lo9 of the pins lo8 are inside the outline of this block 100.
- 22 shows a state in which the push rod 96 is shifted to an upper position. In this upper position, the tips 109 emerge from the outline 100. You are thus able to generate the desired deformations in the cavity of the profile body on the support webs.
- the tips 109 of these pins alternately move back and forth with respect to the outline of the block 100, so that gradual deformations are produced during the back and forth movement of the push rod. Since the pins according to FIGS. 21 and 22 lie opposite each other in pairs, the forces which are transmitted to the push rod 96 via these pins when the support webs are deformed cancel each other out. The guidance of the push rod automatically ensures a symmetrical deformation of the support webs on all sides and thus the maintenance of the rectangular cross-section of the cavity.
- the angle ⁇ by which the slits 102 are inclined in the side surfaces 111 of the block is chosen such that the flank of the emerging tips 109 is flush with these side surfaces. It is thereby achieved that the deformation of the support webs takes place exclusively in the lateral direction and thus damage to the inner surfaces of the profile rails, which bear against the side surfaces 111, is avoided. If the cross section of the cavity of the profile body to be produced deviates greatly from a square, the arrangement of the slots is made according to FIG. 23, after which the slots do not run diagonally but in four half-planes. The central opening and the push rod 96 then have an elongated or oval shape. In this way, the most deformable Angle ß are maintained regardless of the cross-sectional shape of the profile cavity.
- This tool shows a further tool with which the deformations on the support webs are brought about.
- This tool consists of two pairs of disk wheels 121, 122 and 123, 124. These disk wheels are provided with spikes 125 on their circumference. The two pairs of disk wheels sit on mutually parallel shafts 128, 129. Between each pair of disk wheels there is a gear wheel 126, 127. These gear wheels mesh with one another. 24 that when these gears are rotated against one another, the mandrels 125 dig into the base of the support webs 4 and cause the desired deformations there. The distance between the deformations produced in this way corresponds to the distance with which the mandrels 125 are distributed over the circumference of the disk wheels.
- a spring device 134 can be provided which presses the disk wheels apart.
- the mandrels of the disk wheels are arranged offset from one another so that a mandrel of such a disk wheel is always in engagement.
- the disc wheels are coupled to one another via the shafts and the toothed wheels so that the engagement of a mandrel is sufficient to move the two pairs of disk wheels in opposite directions to one another.
- the diameter of the pinion gears 126, 127 can be larger than the diameter of the disk wheels, so that the gear wheels are in contact with one another Intervention while the disc wheels are not touching each other. Furthermore, it can be seen from FIG. 24 that there is enough space between the disk wheels and the gear wheels so that shaft bearings can be arranged there. At these shaft bearings, the feed device for this tool, for. B. a support rod attached.
- a process sequence for the production of a heat-insulating profile body according to the invention will now be roughly described.
- the insulating bars are inserted into a lower profile rail.
- the lower profile assembled in this way is placed on a conveyor, for example a conveyor belt.
- the deformation tool is then inserted with its support rod from above so that only this support rod is located in this preassembled sub-profile and the parts causing the deformation protrude beyond it.
- the upper profile can now be pushed onto the insulating webs, for example, from a roller conveyor without friction on the deformation tool.
- the pre-assembled profile is then brought into the processing position in which the deformation tool slides into the beginning of the profile.
- the preassembled profile body is then pushed over the stationary deformation tool, for example with a carrier attached to the conveyor belt.
- the push rod of the deformation tool is actuated, so that the desired deformations are successively driven into the cavity of the profile body.
- a profile is also loosely preassembled from the profile rails and the insulating webs. Then mandrels for producing the deformations 7 are pressed in from the outside, for example using pliers-like tools. Instead of using pliers, these deformations can also be created by using this pro fil is pushed between two thorned rollers.
- a profile body 1 which consists of an upper profile rail 21 and a lower profile rail 22, between which a right insulating web 31 and a left insulating web 32 are inserted to connect them, the insulating webs 31, 32 being profiled and in undercut grooves 6 engage, which are formed by a holding web 5 and a support web 4, in order to achieve a secure connection between the insulating webs 31, 32 and the profile rails 21, 22 in both the longitudinal and transverse directions, by means of a deformation tool deformations 7 in the support web 4 designed so that they protrude into the interior of the groove 6 so that they abut or penetrate the insulating web 31, 32 (see. Fig. 4o).
- the deformation tool according to the invention is inserted into the cavity 8 enclosed by insulating webs 31, 32 and profile rails 21, 22.
- the deformation tool shown in FIGS. 28 to 35 is designed as will be explained in the following.
- An eccentric drive formed by a crank disk 61 and a connecting rod 62 acts on a push rod and moves it back and forth, or to the right and to the left. 28 shows the push rod 96 in its right dead center.
- the push rod 96 is guided in a guide tube 95, on which a stop member 65 is fastened near the eccentric drive end.
- the attachment of the stop member 65 on the guide tube 95 is advantageously quickly detachable, but must be such that high longitudinal forces can still be transmitted to the guide tube 95, which is essential since the guide tube 95 is very thin-walled due to the limited space conditions caused by the cavity 8 have to be.
- the stop member 65 has a longitudinal bore 66 in which the guide tube 95 is seated.
- the guide tube 95 has two opposite slots 67 perpendicular to the tube axis and in the tube jacket, in which engage the pin 68 guided in the stop member 65.
- the stop member 65 is preferably biased to the right by a spring 69.
- the stop member 65 can be moved back and forth between two end stops 7o and 71 of a stop guide 72.
- the distance between the end stops 7o and 71 can preferably be changed. 28, the stop 65 is shown in its right end position corresponding to the right dead center of the push rod 96.
- the guide tube 95 carries a block 91 at its front end guided in the cavity 8, the connection between block 91 and guide 95 preferably also being a pin connection, as is shown in FIG. 34.
- a pin connection as is shown in FIG. 34.
- another connection for example a screw connection, is also possible if the dimensions of the guide tube 95 and the cavity permit this.
- the block 91 fits snugly in the cavity 8, i. H. its outer dimensions correspond to the cross-sectional shape of the cavity 8.
- the profile body 1 is held under clamping or compressive stress by externally applied clamping rollers 74 with a backstop 75. Due to the backstop 75 and the frictional connection between the pinch rollers 74 and the profile body 1, the latter can only move to the left (FIG. 28), but not in the opposite direction.
- the pinch rollers 74 do not have their own drive.
- no guide rollers 76 (FIGS. 38, 39) having a frictional connection with the profile body 1 can also be provided if the prevention of a movement of the profile body 1 to the right (FIG. 28) is achieved in a different way, as is the case, for example, with reference to FIG. 38 and 39 will be explained in more detail.
- an expanding wedge is fastened, preferably also detachably, for example by means of a pin, the expanding wedge 98 using the eccentric drive. 61 ', 62 can be moved back and forth.
- a pin 81 is guided through the expanding wedge 98 and can slide in the longitudinal slots 82 (FIG. 8) of the swivel arms 92.
- On the pin 81 is outside of the swivel arms 29 between this and the insulating webs 31, 32nd a yoke-shaped ejector 83 is attached.
- the ejector 83 presses the two swivel arms 92 together, ie inwards in such a way that the tips of the teeth 8o have no contact with the support webs 4 of the profile rails 21, 22.
- the ejector 83 is so flat that it has space in the space between the support webs 8 of the two profile rails 21, 22, wherein it is at least partially so wide that it can slide with outer edges on the insulating webs 31, 32. This ensures that the ejector 83 is always symmetrical to the profile axis and not only presses one of the two swivel arms 92 inwards, while the other is still in contact with the profile body 1, i. H. has the support webs 4.
- FIGS. 28 to 32 A complete work cycle is shown in FIGS. 28 to 32.
- the push rod 96 is moved to the left by means of the eccentric drive (FIG. 29), the guide tube 95 initially remaining at rest, ie. H. via its stop member 15 and possibly the spring 69 is in contact with the right-hand end stop 71 of the stop guide 72.
- the spreading wedge 98 is moved to the left and takes the ejector 83 with it, thereby releasing the swivel arms 92. These are pushed apart by the expanding wedge 98 until the tips of the teeth 8o come into contact with the support webs 4 and bite there.
- the spreading wedge 98 first releases the swivel arms 92.
- the ejector 83 also runs to the right, as a result of which the swivel arms 92 are pressed or guided against one another, which in turn releases the teeth 8o from the deformations 7 formed.
- a rightward longitudinal force is also exerted on the swivel arms 92, which also acts on the profile body 1.
- the profile body 1 must remain at rest, which is ensured by the pinch rollers 74 with a backstop 75.
- the stop member 65 initially remains in its left-hand abutment on the end stop 7o (FIG. 32).
- the compressive stress in the push rod 96 corresponds to the tensile stress in the guide tube 95, thereby preventing the arrangement formed from the push rod 96 and guide tube 95 from bending under pressure.
- the lengths of the profile body 1 can be considerable, they are normally 6 m.
- a push rod 96 of this size which has a relatively small diameter, would not be stiff enough without the surrounding guide tube 95 to be able to transmit the required thrust forces, but would rather bend.
- the push rod 96 can bend slightly within the guide tube 95, but only within the narrow limits given by the difference in diameter. A curvature of the guide tube 95 is prevented by the tensile stresses.
- the thrust of the push rod 96 not only achieves the formation of the deformations 7 in the support webs 4, but also by the interaction with the pinch rollers 74 with a backstop 75 Longitudinal movement of the profile body 1 by an increment a, which corresponds to the distance between adjacent deformations 7 in a support web 4.
- These pitch a corresponds to the stroke of the stop member 65 between the end stops 7 0, 71 of the stopper guide 72.
- the drive for the deformation process therefore takes place solely by means of the eccentric drive, ie by the rotary drive of the crank disk 61.
- the profile body 1 only has to absorb very small longitudinal forces, namely only those caused by the friction of the ejector 83 on the insulating webs 31, 32.
- the tool according to the invention can be designed to be light and disassemblable, as a result of which the entire shaping tool becomes cheap, which in turn reduces the production costs of the profile bodies.
- the frictional engagement of the pinch rollers 74 on the profile body can be achieved, for example, by means of a double spindle guiding the pinch rollers 74 against the profile body 1.
- the deformations 7 can be formed in only one profile rail if only a lower profile rail 22 is provided with the insulating webs 31, 32 and an upper profile rail 21 is missing.
- the articulation of the spreading or swivel arms 92 on the block 91 takes place per swivel arm 92 by means of the block 91 Brought pins 84.
- These pins 84 engage in openings or bores 85 in the swivel arms, the bores 85 being somewhat larger or larger than the diameter of the pins 84.
- the play achieved in this way is sufficient to make this connection sufficiently articulated.
- the swivel arms 92 only have to cover a relatively small distance at the front end, ie in the area of the teeth 8 0 , which is of the order of 3 mm, for which a freedom of movement of + 1.5 mm is sufficient.
- a small leaf spring 86 on the block 91 presses on one of the swivel arms 92 from the outside and holds the swivel arm 92 at its linkage 84, 85 in such a way that the swivel arm 92 can be attached to the block in a simple manner and, if appropriate, can be detached therefrom, which of course only occurs when block .91, swivel arms 92 and ejector 83 are removed from the cavity 8.
- the force effect of the teeth 8o on the support webs 4 is determined by the stroke of the crank disk 61, i. H. determined by their diameter, because the stroke of the crank disk 61 from the position shown in FIG. 3o to the position shown in FIG. 31 determines the force of the teeth 8o on the support web 4.
- the stop member 65 has reached its left-hand abutment on the end stop 70, a further rotation of the crank disk 61 up to its left dead center now causes the teeth 80 to penetrate into the support webs 4.
- the spring 79 is provided, by means of which the stop member 65 is forcibly moved in its right-hand abutment against the 'end stop 71, the spring' 69 also ensuring that the guide tube is held in its right-hand end position for as long as it is until the teeth 80 are sufficiently bored in the support webs 4 sen (Fig. 29) to thereby achieve the promotion of the profile body 1 to the left (Fig. 3o).
- the ejector 83 need not be yoke-shaped.
- the ejector 83 can also be formed only by two legs 87, which are essentially wedge-shaped, the apex area being connected to the expanding wedge 98.
- the legs 87 are only guided between the support webs 4.
- the base ends of the legs 87 can also be connected to one another by a relatively weak spring 88 (FIG. 36) which only serves to fix the two legs 87 so that they do not fall apart.
- a return force is generated only in that the legs 87 are wedge-shaped and thereby force themselves between the swivel arms 92 and the insulating webs 31, 32, i. H. that the legs 87 of the ejector 83 are supported on the flanks of the insulating webs 31, 32 and the swivel arms 92 are forced inwards by the wedge action when the wedge 98 is pulled back.
- the spring 88 can also be made strong enough to achieve the return force.
- the expansion wedge 98 need not necessarily have a triangular cross section, it can also have a trapezoidal cross section, if the width of the cavity 8 is such that when the swivel arms 92 are moved inwards, a relatively greater distance remains between them. In narrow cavities 8, however, in which the inwardly moving pivot arms 92 practically abut one another, an expanding wedge 98 with a triangular cross section must be used so that the apex can engage between the two pivot arms 92.
- FIG. 37 Another deformation tool according to the invention is shown in perspective in FIG. 37.
- This deformation tool has two bands 14o, 141, preferably made of steel, which are inserted into the profile cavity 8 of the preassembled profile body 1.
- the bands 14o 141 are similar in strength and quality to the band saw of a band saw.
- the two bands 14o, 141 are as high and as long as the cavity 8.
- Each band 14o has bulges or teeth 142 at the lower or upper edge, by means of which the desired deformations 7 can be formed.
- an expanding wedge 143 is guided through the cavity 8 between the bands 14o and 141 by means of a push rod 144.
- the base width of the expanding wedge 143 corresponds essentially to the width of the cavity 8 in such a way that the bands 14o, 141 are pressed apart to such an extent that the teeth 142 penetrate into the support webs and form the desired deformations 7.
- an ejector is guided through the cavity 8 in a subsequent work step or at a distance from the expanding wedge 143.
- the ejector consists of a right ejector part 145 and a left ejector part 146, both of which are wedge-shaped and are guided by means of push rods 147 and 148, respectively.
- the ejector parts 145, 146 are guided into contact with the insulating webs 31, 32 between the supporting webs 4 so that their apices engage between the belts 14o, 141 and the insulating webs 31 and 32, respectively, and thus release the teeth 142 from the deformations 7.
- the tapes 14o, 141 can then be pulled out of the cavity 8 and removed.
- this deformation tool can achieve faster production than the deformation tool explained with reference to FIGS. 28 to 36.
- the pulling or pushing device must be made correspondingly more stable and work with high forces.
- the pre-assembled profile body 1 must be guided and fastened so well that it can absorb high tensile and / or compressive forces.
- profile bodies 1 are to be manufactured with differently dimensioned cavities 8, differently dimensioned bands 14o, 141 must be provided, which can result in considerable stockkeeping.
- the longitudinal conveying of the profile body in the deformation tool according to FIGS. 28 to 36 is achieved by the deformation tool itself, movement of the profile body 1 in only one direction being ensured by the pinch rollers 74 with backstop 75.
- the deformation tool en end is shown in FIG. 28 at the left malli g of a pre-assembled profile body 1. It is thus situated in the starting position.
- the preassembled profile body 1 lies on a roller conveyor made of rollers 15o.
- the profile body 1 is at the beginning of the operation on the right-hand rollers and at the end of the operation on the left-hand rollers.
- a double chain hoist 151 is guided over part of the rollers 15o, the spacing of which is not less than the length of the longest profile body 1 to be processed.
- Arms 153 which carry a slide 154, are fastened to the chain hoist via joints 152.
- the slider 154 has a tunnel-like opening 155 of a dimension which is larger than that of the block 91, but smaller than the cross-sectional dimension of the profile body 1, i. H. that the deformation tool can be guided through the tunnel-like opening 155.
- lateral guide rollers 76 are provided at the level of the teeth 8 0 of the deformation tool, as mentioned above, which rest on the profile body 1 on the outside.
- This system can, for example, also be spring-loaded.
- These lateral guide rollers 76 merely ensure that the profile body 1 and thus the block 91 are always in the correct position with respect to the tunnel-like opening 155, so that tunnel-like opening 155 and block 91 cannot hang together.
- One of the rollers 150 over which the chain hoist 151 is guided here the right-hand roller 156, is connected to a rotary drive 157.
- This rotary drive 157 constantly exerts a weak torque in the counterclockwise direction (FIG. 38), which is just sufficient to tension the chain hoist 151 and to overcome frictional resistance, but which is too weak, however, for the profile body 1 to be created by means of the slide 154 to move to the left.
- a rotary drive 157 can for example, be provided with a slip clutch or a torque limiter to achieve this.
- the rotary drive 157 or the right-hand driven roller 156 have a backstop so that the chain hoist 151 can only be moved in the conveying direction of the profile body 1.
- the slide 154 When the rotary drive 157 of the driven roller 156 is switched on, the slide 154 is first moved until it strikes the right-hand end of the preassembled profile body 1, whereupon a rest position is reached due to the torque limitation. If the eccentric drive 61, 62 of the deformation tool is then put into operation, the work process which has been explained with reference to FIGS. 28 to 32 takes place, the slide 154 together with the backstop of the driven roller 156 or of the rotary drive 157 achieves the same effect as the pinch rollers 74 with backstop 75 in the procedure according to FIG. 28.
- clamping rollers 74 ie. H. a dimension-dependent merging of the pinch rollers 74 is omitted.
- profile bodies 1 which have complicated or irregular profile cross sections can also be provided with deformations 7 as a result.
- a conveyor belt can also be used instead of the roller conveyor with chain hoist 151.
- the slider 154 can be formed in two parts, the two parts being connected to the conveyor belt via a plurality of joints 52.
- the guide tube 95 and block 91 have free passage both upwards and downwards.
- an end scarf which can be actuated by the slide 54 ter 159 should be provided so that when the slide 54 actuates or triggers the limit switch 159, the drives are stopped because the profile body 1 to be machined is provided with deformations 7 over its entire length, ie the limit switch 159 is located somewhat further left (Fig. 38, 39) as the teeth 8o of the deformation tool.
- the drives can also be switched off in another way, for example by means of a light barrier or the like.
- the slider 154 can still be folded to the right because of the joints 152 (FIG. 38).
- the lower profile rail 22 with the inserted insulating webs 31, 32 can be set or placed so far to the right (FIG. 38) that the block 91 projects to the left to the front.
- the upper profile rail 21 can be put on and the pre-assembled profile body 1 can then be moved to the left so far that the block 91 with the swivel arms 92 disappears in the beginning of the profile.
- the slide 154 is folded to the left or upwards, after which the drives 157, 61, 62 can be put into operation.
- the latter can also be started automatically by control via switches or light barriers or the like.
- At least one further slider 158 can also be provided, which is attached in the same way to the opposite point of the chain hoist 151 or the conveyor belt.
- the second slide 158 is already in the starting position or shortly before. If profile body 1 are used that are shorter than the maximum length suitable for use in the device, can the rotary drive 157 can be switched so that it continues to run until the respective slide 154, 158 reaches the starting position now correspondingly further to the left.
- the device explained with reference to FIGS. 38 and 39 can also be used with the deformation tool explained with reference to FIG. 37.
- FIGS. 51 and 52 show further embodiments for the deformation rails or the belts, with which the deformations in the support webs or the bending of the support webs with deformation rails are brought about in the method already described.
- FIG. 51 shows a flat profile as the deformation rail 14o, in which protrusions or teeth 142 of various types are attached to the upper edge 163 in the left part of the figure.
- the middle part of FIG. 51 shows a deformation rail in the form of a flat profile, which is chamfered in the area of its edge 163 in order to cause the support webs to be bent during the spreading movement.
- a combination is shown in which both bevels and bulges 142 are present. These bulges do not have to extend to the edges of the deformation rail, but, as the right part of FIG. 51 shows, can also end at a certain distance in front of the upper edges 163 of the deformation rails.
- FIG. 52 shows a deformation rail 141 designed as a band. Various rails are located on it Bulge, n 142, which are formed as teeth in the left part of Figure 52, as continuous ribs in the right part of the figure. A bulge 142 is shown in the middle of FIG. 52, which has both teeth and a continuous rib-shaped part.
- FIG. 53 shows a further embodiment for the deformation rails of the deformation tool according to the invention.
- the deformation rails 14o, 141 have a U-shape.
- the free legs 169 of these U-profiles are each provided with a toothing 17o.
- the teeth interlock so that when the expansion wedge is pulled through, the deformation rails 14o, 141 cannot move against one another.
- Fig. 52 the spreading movement of the deformation rails is indicated by the arrows.
- FIG. 54 shows a section through a loose, preassembled profile body made of profile rails 2 and insulating webs 3, into which another embodiment of deformation rails 14o, 141 according to the invention is inserted.
- the deformation rails are chamfered on the sides to the support webs 4, so that the support webs are folded against the insulating webs 3 when the deformation rails are driven apart.
- the deformation rails have a U-profile, the distance between the legs of this U-profile of the two rails being dimensioned such that the deformation rails fit into one another. The expanding wedge is pulled through the cavity enclosed by the deformation rails.
- FIGS. 55a and 55b show further forms of embodiment of a deformation tool according to the invention.
- the deformation rails 14o, 141 have lugs 166 'which protrude into corresponding guide grooves 177 of the expansion wedge 143.
- the arrangement of the lugs 166 and the corresponding grooves 177 of the expansion wedge causes an accurate alignment of the deformation rails 14o, 141, so that during the expansion process a displacement of the profile rails 2 against each other is avoided and an exact rectangular shape of the profile body is achieved.
- this can have a continuous projection 168 in its longitudinal direction or also several individual projections that protrude into the space between the support webs 4. This also ensures a precise fit of the deformation tools.
- FIG. 55b shows an alternative embodiment to the embodiment according to FIG. 55a.
- the lugs are not attached to the deformation rails 14o, 141, but rather to the expansion wedge 143.
- the guide grooves 167 are on the. Deformation rails 14o, 141 formed.
- FIG. 56 illustrates a method in which a sealant or adhesive is pressed into the space between the supporting webs 4 and the insulating webs 3.
- a pasty strip 15 of the desired mass is first applied to the inner surfaces of the insulating webs 3. If the mass of which the strip 15 is made is sufficiently firm, this strip can be applied to the insulating webs 3 before the profile body 1 is preassembled.
- the material of the strip 15 is then pressed into the intermediate spaces 14 with an application device, which has a heatable roller 26, for example.
- the arrow indicates that the roller 26 is pressed against the pasty strip 15.
- the roller and another application device also run sealingly on the inner surfaces 44 of the support webs 4, so that the material of the strip 15 cannot escape into the cavity 8.
- FIGS. 57 and 58 schematically show a first production method for a profile body according to the invention using two deformation rails 141, 142 and the expansion wedge 143.
- the deformation rails 14 0 , 141 and the expansion wedge 143 are attached to it Tie rod 144 combined into a package.
- the expansion wedge 143 is located in a recess in the deformation rails.
- a sleeve 162 for receiving a tie rod is also attached to the deformation rails.
- the package of deformation rails, expansion wedge and tie rod is inserted into the cavity 8 of the profile body 1 so that the bulges or teeth 142 are opposite the support webs 4.
- the tie rod 18o is then suspended in the holder 162 and the expanding wedge is pulled through with the aid of the tie rod 144 (to the left in FIG. 58). Due to the spreading, the deformation rails 14o, 141 are pressed against the support webs 4 and the latter are thereby deformed. 58 at the left end of the cavity 8, the arrangement formed by the deformation rails 14o, 141 can be pulled out of the cavity of the finished profile body.
- FIGS. 59 and 6o illustrate a further method according to the invention, in which the supporting webs 4 are not provided with individual deformations, however, but rather are folded over their entire length against the insulating webs.
- the shaping tool consists of two flat profiles serving as shaping rails 14o, 141, which are chamfered at their edges lying towards the supporting webs. At the free ends, which protrude beyond the profile body, a hole is made as a holder 162 for the tie rod 18o in each of the profile rails.
- the tie rod is formed in the example shown in Fig. 59 and 6o, for example, of two bolts which into the ent engaging speaking holes of the two deformation rails.
- the engagement of the bolts can be done in such a way that they are pressed into the bores by means of a compressed air cylinder, but it is also possible for these bolts to be fixed and engage in the bores 162 due to the expansion movement caused by the expansion wedge.
- the pull rod 144 is designed as a narrow, high profile. Such a design of the tie rod is particularly recommended when deforming narrow profiles, which present greater difficulties because of the limited space available.
- a package which is formed from the deformation rails 14o, 141 and the expansion head 143 with its pull rod 144, is inserted from left to right into the cavity of the profile body 1. Then the deformation rails 14o, 141 are temporarily blocked by a stop 165 and the pull rod is retracted to such an extent that the bores 162 pass over the bolts of the tie rod 18o due to the spreading movement and thus the tie rod snaps into place. Then the stops 165 are removed and the expansion head 143 is pulled to the left.
- the ends 161 of the deformation rails 14o, 141 facing the expanding wedge it is also necessary to allow the ends 161 of the deformation rails 14o, 141 facing the expanding wedge to extend beyond the profiled body 1 so that the expanding wedge 143 is pulled through to such an extent that it clears the bore 162, so that a continuous through these bores Bolt can be inserted.
- the ends 162 of the deformation rails facing away from the expanding wedge 142 are initially blocked by stops 165.
- the deformation rails on their surfaces 164 facing the support webs are only beveled (see FIG. 6 0 ), but they can also be provided with individual projecting teeth.
- 61 illustrates a further embodiment of the production method for a profile body, in which the deformation rails 14 0 , 141 are connected to one another by means of an articulated bridge 171.
- the articulated bridge 171 surrounds the expanding wedge 143. The entire arrangement is inserted into the cavity of the profile body 1 in a manner corresponding to the procedures already described, then the tie rod is hung in and then the expanding wedge 143 is pulled out on its tie rod 144.
- the articulated bridge 171 has the particular advantage that the deformation rails 14o, 141 remain connected to one another so that they are easier to handle.
- the deformation tool consists of a drawing slide 14o, which carries two pairs of disc wheels 121-122, 123-124.
- the drawing carriage 14o runs between the disk wheels of each pair and has bores in which the axles 128 of the disk wheel pairs are mounted.
- 62 schematically shows that the disk wheels have individual bulges 141 which extend across the circumferential surface of the disk wheels. If the pulling slide 14o is pulled through the cavity of the loosely preassembled profile body, these disc wheels roll on the supporting webs 4 and, with their bulges 141, bring about the deformations of the supporting webs. As also shown in FIG.
- the disk wheels have toothings 142 so that the two pairs of disk wheels are in engagement with one another.
- Disc wheels of this type can be produced in a simple manner, for example by grinding a waist in the middle of a commercially available, roller-shaped gear wheel, the remaining central part then forming the axis of the pair of disc wheels. Do they stand Teeth of such a gear so closely together that when pulling and deforming the support webs there is no longer a sufficient distance between the individual deformations, the entire support web can be sheared off.
- a part of the teeth is ground, for example every second or always two of three teeth, so that the teeth are so far apart that they roll on the support webs deform only at individual points.
- the teeth can be ground conically, as shown in Fig. 64 for the upper disc wheel 121.
- the ground teeth 148 produce further small deformations 147 between the deformations 7, which originate from the bulges 141, which are located on the upper edge of the support web (FIG. 66).
- the excess, disruptive teeth are ground so far by a roller-shaped gear that they no longer touch the support web. This case is shown in Fig. 64 in the lower part.
- the remaining toothing 142 serves to hold the two pairs of disk wheels in engagement, as is shown in FIG. 62 for the disk wheels 122 and 124.
- Fig. 63 shows another pair of disc wheels, which are designed conical. The distance between the remaining teeth is so great with these disc wheels that rolling of the wheel on the support web may no longer be guaranteed.
- the teeth of the upper disk wheel 121 are set to the teeth of the lower disk wheel 122 and the two disk wheels are firmly connected to a rigid axle. When pulling the slide carriage 14o through the profile cavity, it comes always alternately above and below a tooth with the support web in engagement, so that a total rolling movement of the disc wheels 121, 122 is secured.
- the two pairs of disk wheels are not fitted at the same height as the drawing slide, but are offset with respect to one another in the longitudinal direction. This case is shown in Fig. 65.
- guide rollers 143 can be attached to the drawing carriage 14o, which are supported on the support webs or also on the insulating webs and prevent the drawing carriage 14o from tilting when being pulled through the profile cavity.
- the drawing slide must be designed to be separable for the installation of the disk wheel pairs.
- slots 149 are cut into the body of the drawing slide from the side, into which the disk wheel pairs with their axes 128 are inserted. These slots are indicated in Fig. 65 by the dashed line.
