Definitions
- the present invention relates to a method for joining a link chain link, in which at least one link with at least one bolt is connected to one another by a pressing and aligning process. Furthermore, the invention relates to an apparatus for performing the method.
- the chain links are usually assembled from below. This means that the lower tab is positioned first and the associated bolt is fed in. In the manufacture of an inner chain link, the link and the sleeve are then centered relative to one another by means of a positioning mandrel protruding from the assembly plane. Then the lower tab and sleeve are pressed. If necessary, a roll can be placed on the sleeve before or after this process. Finally, the upper tab is fed in and likewise centered on the sleeve by means of a positioning mandrel and then pressed on. This procedure is carried out in benen cycle steps, so that a common press ram working with a certain number of strokes each applies the pressing force. This can be done at a rotary table or in series.
- This object is achieved according to the invention by a method for joining a link chain link of the type mentioned at the outset, in which the at least one pin is centered centrally on a chain main axis by simultaneous active application of symmetrical tensioning forces on the end faces of the pin and the at least one link plate by means of a joining stroke relative to Pin is pushed into a position symmetrical to the main chain axis on the pin.
- the method according to the invention differs mainly from the methods in the prior art in that here the centering of the bolts is not against one Fixed stop is worked, but rather a central centering by simultaneous application of symmetrical clamping forces.
- active application is of particular importance here, since in the prior art the force is always applied only from one side, while the other side stands still during this process and acts as a stop (passive application of force).
- the difference now lies in the fact that in the prior art the dimensional stability, in particular the symmetry to the main chain axis, is determined by the end face of the chain pin which lies against the stop.
- the center of the main chain axis is always found exactly, since the bolt automatically aligns itself with this axis through the active application of symmetrical tensioning forces.
- the principle is similar to a pair of pliers, in which the pressing forces are also applied symmetrically to a line of symmetry running through the pivot axis of the pliers.
- the advantage is that the chain pins do not necessarily have to be manufactured with a very small tolerance, since the end faces of a pin are always the same distance from the main chain axis. This also opens up the possibility of simultaneously centering the two bolts of a chain link by means of one process if they are each subjected to symmetrical tensioning forces.
- the joining stroke is carried out by pushing the at least one link onto the at least one bolt, and the at least one link is pushed in a position symmetrical to the main axis of the chain by simultaneously applying symmetrical joining forces.
- the application of force during the joining stroke can only take place on one side of a tab, as long as it is ensured that a symmetrical pair of forces is applied at the end of the joining stroke in order to arrange the tabs symmetrically or to center the one tab in the middle.
- the tabs are then also extremely precisely aligned with the main chain axis.
- the joining stroke is carried out by inserting the at least one pin into the at least one link plate and at least at the end of the joining stroke the at least one pin is centered by the simultaneous active application of the symmetrical tensioning forces to the main chain axis .
- the tabs are not pushed onto pre-centered bolts, the at least one bolt is inserted into an opening of the tab and then the bolt is centered.
- the tab can be firmly anchored in position during such a process.
- Such a procedure is mainly used for pin brackets for duplex chains, since the pin has to be pushed open long distances relative to the plate.
- a further method step can advantageously be provided, in which the at least one tab and the bolt are prepositioned with respect to one another, so that an opening in the tab is arranged coaxially to the bolt.
- the fact that the entire chain link can be pre-positioned and joined in a common centering and pressing process can also be described as new, regardless of the number of bolts and plates.
- the method according to the invention enables these to be carried out in a single joining station. On the one hand, this allows the actual pressing process to be run at a lower speed, so that more favorable pressing conditions with less heat development are present. On the other hand nevertheless, at least maintain the number of manufactured parts, if not increase them per unit of time.
- the at least one tab is guided coaxially to the bolt and is already partially pressed onto the bolt.
- the tabs are centered on the bolt, so that these attachment forces do not have to be additionally applied by the actual joining stroke.
- the joining stroke can be carried out by an upper and / or a lower hollow punch arranged around the positioning mandrels, which apply the symmetrical joining forces. Since the positioning mandrels generally have a diameter which essentially corresponds to the outside diameter of the bolt (usually slightly smaller), the hollow punch also provides guidance when the tabs are pressed on. This is of enormous advantage in particular when a single tab is pressed into the center of a long bolt in a duplex outer chain link, since the long bolt cannot be bent away.
- the joining stroke can only be applied by a hollow punch when a single tab is pushed on, and that the tab is aligned at the end of the joining stroke by pressing the second hollow punch against it. It may be desirable that the joining stroke is carried out by a positioning mandrel and the symmetrical clamping forces for a bolt are applied by positioning mandrels which can be moved uniformly and uniformly towards one another. This means that a bolt (sleeve) is pressed into a tab by means of the positioning mandrel, and centering only takes place towards the end of the joining stroke by engaging the second positioning mandrel from the opposite side.
- the invention relates to a device for joining a link chain link.
- the device comprises an axially movable, upper positioning mandrel and an axially movable lower positioning mandrel, between which a pin of the chain link can be positioned and clamped, a lifting mechanism by means of which the positioning mandrels can be displaced at right angles to a main chain axis and by means of the symmetrical tensioning forces on the main chain axis active End faces of the bolt can be applied so that the bolt can be centered in the center of the main chain axis, and an upper punch and a lower punch, by means of which the at least one link plate can be brought into a position symmetrical to the main chain axis or clamped therein.
- This device is constructed in such a way that it centers the at least one pin of the chain link in a joining operation and pushes the at least one link onto the pin.
- the bolt can also be inserted into the tab.
- a positioning mandrel is used to apply a clamping force.
- Previously used positioning mandrels were mainly used for coaxial alignment and not for the application of axial forces. In this respect, it would be possible to manufacture a joining head according to such a principle, which produces a chain link by means of a single joining process or completes a chain by assembling an outer chain link with the interposition of an inner chain link. The alignment to the main chain axis is part of the joining process.
- the lifting mechanism must have a symmetrical positive coupling of the positioning mandrels. This can also be done hydraulically or pneumatically, but preferably mechanically.
- a kind of pliers principle offers itself as a simple solution in this context.
- a lifting mechanism is provided for displacing the upper and lower punches, by means of which they can be displaced symmetrically and at right angles to a main chain axis and by means of which symmetrical joining forces which are active at the same time as the main chain axis can be applied to carry out the joining stroke, so that the at least one tab can be pushed symmetrically onto the bolt.
- it can be the same lifting mechanism as for the positioning mandrels. In most cases, however, a separate lifting mechanism arranged parallel to this is used, since the punches have to be actuated differently than the positioning mandrels. In any case, this preferred also positively coupled lifting mechanism provides sufficient symmetry of the tabs on the bolt.
- a simplified version of the device can provide that the punches are designed as a movable and a fixed clamping jaw, by means of which the at least one link plate can be clamped in a position that is substantially symmetrical with the main axis of the chain, and that the joining stroke can be carried out by the at least one positioning mandrel.
- the punches are adjusted in such a way that the link plate can be clamped between them essentially symmetrically to the main chain axis.
- the tab then does no further alignment movement during the joining process.
- the bolt is then inserted into the link on one side and centered symmetrically to the main chain axis at the end of the joining stroke due to the symmetrical application of the clamping forces.
- the lifting mechanism for the two positioning mandrels can advantageously comprise a common drive with positive guidance, by means of which the two positioning mandrels can be moved coaxially and symmetrically to one another. This greatly simplifies the lifting mechanism, since a single drive moves both positioning mandrels. A positive control then ensures the symmetrical implementation of the displacement path and the displacement speed specified by the drive.
- the lifting mechanism for the upper and lower punches can also comprise a common drive with positive guidance, through which the two punches can be moved coaxially and symmetrically to one another. The same advantages apply here as for the common drive of the positioning mandrels.
- the drive comprises a sliding bush which is controlled in its linear movement by a cam disk and which moves the positioning mandrels or the stamp via a symmetrical lever linkage
- the drive for the stamps and the drive for the positioning mandrels since both Cam discs can be driven together.
- the guidance by means of a cam disc and a controlled sliding bush is very robust and can exert the necessary forces which are necessary to compress the chain links.
- the positive guidance works very precisely and is precisely adjustable.
- the centering and joining forces can be generated symmetrically using a few components.
- the lever linkage can be changed very easily, so that in addition to the control by the cam, there is also an adjustment option via the lever linkage or its complete replacement.
- At least one lever section of the lever linkage can be designed to be adjustable in length. In this way, the travel path of a positioning dome or a stamp can be set in a very simple manner. Suitable adjusting devices allow a very high precision of the setting.
- the entire lifting mechanism is greatly simplified in its construction in that an overload protection that can be deflected in its length is provided between the sliding bush and cam disc and / or in the lever linkage.
- This overload protection also compensates for the different lengths of the bolts or the thickness of the tabs. This means that as soon as the necessary clamping force is applied and, for example, a further displacement force is exerted by the cam on the sliding bush, but this cannot move any further, the path length generated by the cam is compensated by the overload protection.
- Such a possibility of deflection can also be applied at any other suitable position of the lifting mechanism. be ordered.
- the positioning mandrels and stamps themselves can also have suitable spring-in devices which spring in as soon as a certain force is reached. This is most favorable for the positioning mandrels, since the centering force would increase very rapidly as soon as both positioning mandrels are brought into contact with the end faces of the bolt.
- the positioning mandrels applying force they can be guided in coaxial bores of the punches and can be moved relative to the latter. This intimate arrangement of the punch and positioning mandrel also ensures exact alignment and positioning.
- the positioning mandrels can comprise a cylindrical projection which can be inserted with a precise fit into the bore of a hollow pin of an inner chain link and defines an annular stop step to the adjacent area of the positioning dome, which can be brought into contact with an end face of the hollow pin is.
- the shoulder therefore moves into the hollow pin, ensures coaxial alignment there, and the stop stages of the opposite positioning pins then ensure symmetrical centering with respect to the main chain axis.
- a deformation of the end face area by the annular stop step can not take place due to the cylindrical approach.
- the positioning mandrel can comprise a centering area which can be moved into the opening of the tab and aligns it coaxially with the hollow bolt. Accordingly, the tab is precisely aligned by the positioning mandrel before it is pushed onto the bolt.
- this also means that the feed devices only have to ensure pre-positioning within a wide tolerance range and the actual centering is carried out by the positioning mandrel. This also greatly facilitates feeding.
- the centering region is frustoconical. is. In any case, this creates a centering, regardless of the size of the opening within the tolerance range.
- the entire joining process can be further refined and improved in that the centering area and the stop step are designed in such a way that a slight joining stroke for attaching the tab to the outer jacket of the hollow bolt can be carried out by the positioning mandrel before the stop step abuts the end face of the hollow bolt.
- the position of the stop step and the length of the centering area and its shape are matched to the opening, in particular the thickness of the tab, in such a way that a corresponding attachment process takes place. For example, a quarter of the tab can already be pushed onto the bolt by this process.
- the punches In order to be able to press onto the tab as large as possible, in one embodiment the punches have a substantially flat and perpendicular to the mandrel axis surrounding the associated positioning mandrel, which is displaceable relative to the positioning mandrel and presses the tab onto the outer jacket of the hollow bolt. Tipping forces on the tab are avoided because it lies on the stamp surface over a large area.
- the upper and / or lower punch can have an extension which moves on block during the joining stroke and defines or defines a precise joining distance between the punch surfaces at the end of the joining stroke. This is particularly useful when two tabs are to be pushed onto the end areas of a bolt. The extension then defines the distance between the two tabs so that they are pushed on symmetrically, but a precisely defined distance remains between the two. For protrusions traveling on blocks, an overload protection may have an advantageous effect. For most chain links, it is desirable to manufacture them with a single joining process. This fact is best taken into account according to one embodiment in that two upper positioning mandrels and two lower positioning mandrels are arranged in a jointly assigned upper and lower punch to form a joining head.
- Such a joining head bridges the fluctuations in the length of two bolts.
- a compensation for the tabs is not necessary, since it can be assumed that a tab does not fluctuate in thickness. This results in a very simple and compact structure that completely fulfills the requirements placed on the joining process.
- a feed device which pre-positions all the elements of a chain link and feeds them to a joining head in a pre-aligned manner. This is also a novelty, since up to now the individual parts have mostly been fed separately and then connected to the previously prepared components at a corresponding joint. The pre-positioning and feeding of all elements at once, so that the connection of all components to one another is produced by a single joining operation, has not previously existed with this quality in the prior art.
- the device according to the invention is capable of finishing the chain link with a single joining operation. So far, chain links have always been built up in layers, with a joining stroke being carried out for each layer.
- the aim of this invention was in particular to provide a method and a device in which the press fit can be produced in a single operation, even with pin blocks for duplex chains. Subsequent alignment or further displacement of the tabs and bolts relative to one another, which would in each case be accompanied by a weakening of the press fit, is avoided.
- the device can operate at relatively low joining speeds, since relatively small strokes have to be generated in the joining head, and due to the joining steps reduced to a single joining operation, a higher output of chain links can nevertheless be obtained.
- this is a forced assembly, in which all components during the Joining process are forced. The components are therefore extremely precisely aligned with each other.
- Fig. 3 is a schematic diagram of a lifting mechanism for controlling the positioning mandrels or the stamp and
- Fig. 4 three possible variants of adding symmetrical link chains in full section.
- Fig. 1 the positions of the essential components of a joining head are shown in each of the three process steps.
- This comprises two upper cylindrical positioning mandrels 1 and 2, which are each arranged axially displaceably along the axes A and B, respectively.
- Coaxial to the positioning mandrels 1 and 2 correspondingly assigned lower positioning mandrels 3 and 4 are provided, which are likewise cylindrical and are arranged to be displaceable along the axes A and B, respectively.
- the positioning mandrels 1 and 2 are each arranged in a corresponding cylinder bore 5 or 6 in a common upper punch 7 or in a common lower punch 8.
- the punches 7 and 8 are each displaceable relative to the associated positioning mandrels 1 and 2 or 3 and 4 parallel to the axes A and B.
- the positioning mandrels each have a coaxial cylindrical projection 9, which projects beyond a certain amount over a stop surface 10 of a circumferential stop stage 11.
- the stamps 7 and 8 have a stamp surface 12 which runs parallel to the stop surface 10 and is arranged perpendicular to the axes A and B and the positioning mandrels 1 and 2 or 3 and 4.
- the entire joining head is used in the present example for joining an inner chain link 13, which consists of two parallel, plate-shaped plates 14 and 15 with cylindrical openings 16 and two cylindrical hollow bolts 17 and 18 arranged parallel to one another.
- An inner chain link 13 consisting of these elements is also shown at the top left in FIG. 4. It is shown in an exaggerated manner that the end regions of the hollow bolts protrude beyond the outer sides 19 and 20 of the tabs 14, 15.
- the protrusion of the hollow bolts 17, 18, that is, the distance of the end faces 21 and 22 from the associated outer sides 19 and 20 of the tabs 14 or 15 is characterized by the dimension X.
- the dimension X should be the same size on both sides, so that symmetry arises.
- the outer sides 19 and 20 of the plates 14 and 15 should have the same distance Y from the main chain axis K A. It also follows that the end faces 21 and 22 should also have the same distance from the main chain axis K A.
- the dimension Y is the same on both sides of the inner chain link 13
- the dimension X can be different if the hollow bolts 17 and 18 have different length dimensions.
- the symmetry to the main chain axis K A should always be maintained.
- the two tabs 14 and 15 and the associated hollow bolts 17 and 18 are separated by known measures and fed to the joining head by means of a pre-positioner.
- the individual parts are already held in the prepositioned position (see left position in FIG. 1). It means that the openings 16 and the hollow bolts 17 and 18 are already arranged essentially coaxially to one another and the tab 15 is arranged below the hollow bolts 17 and 18 and the tab 14 is arranged above them. Since a positioning with the positioning mandrels 1 and 2 or 3 and 4 is carried out subsequently, the pre-positioning can be carried out with relatively coarse tolerances. It is only important that all four components are fed to the joining head in this arrangement at the same time.
- the positioning mandrels 1 and 3 and 2 and 4 move towards one another uniformly and uniformly along the axes A and B, respectively.
- the positioning mandrels 1 to 4 each move into the openings 16 of the tabs 14 and 15 until the cylindrical projections 9 engage in the center of the bore 17 'or 18' of the hollow bolts 17 and 18 and these coaxially to the positioning mandrel 1 and 2 or 3rd and align 4.
- the stop surface 10 of the positioning mandrels 1 and 2 comes into contact with the end faces 21 and the outer surface 10 of the positioning mandrels 3 and 4 with the end faces 22 of the hollow bolts 17 and 18.
- the tabs 14 and 15 are aligned on the outer circumference of the positioning mandrels 1 to 4, so that the openings 16 assume an exact coaxial position with respect to the axes A and B.
- the positioning mandrels 1 and 3 or 2 and 4 are not only moved towards one another uniformly and uniformly, but now also exert the same forces (symmetrical application of force) on the end faces 21 and 22.
- this is centered symmetrically to the main chain axis K A.
- This process is shown in the middle position of FIG. 1. It can clearly be seen that the positioning mandrels 1, 2, 3 and 4 have moved out of the punches 7 and 8.
- the stamps 7 and 8 apply a symmetrical joining force by moving them uniformly and uniformly.
- the stamps 7 and 8 slide along the outer surfaces of the positioning mandrels 1 to 4 and press with their stamp surface 12 on the outer sides 19 and 20 of the tabs 14 and 15.
- the tabs 14 and 15 are thereby on the outer surface of the hollow bolts 17 and 18 pressed a certain amount.
- a stop not shown, ensures that the movement of the punches 7 and 8 towards one another stops at a certain point, so that the distance between the outer surfaces 19 and 20 of the tabs 14 and 15 is exactly determined. Due to the symmetrical application of joining forces, the plates 14 and 15 are also arranged symmetrically to the main chain axis K A.
- a complete joining process can be carried out by means of a single joining head, for which several joining steps were necessary in the prior art in order to achieve sufficient quality.
- the number of pieces to be produced can be increased compared to the prior art, even if the joining speed is much lower in one joining step.
- a low joining speed e.g. 250 sleeves per minute
- FIG. 2 A cross section through a joining head is now shown in greater detail in FIG. 2.
- the pre-positioned inner chain link 13 is supplied by means of a turntable 23, which essentially consists of an upper plate 24, a lower plate 25 and an intermediate plate 26.
- the upper plate 24 has cutouts 27 for receiving the upper tabs 14 and the lower plate 25 has cutouts 28 for receiving the lower tabs 15 on.
- the recesses 27 and 28 are adapted to the outer contour of the tabs 14 and 15, so that they are received essentially in the correct position.
- the intermediate plate 26 also open recesses 29 are formed into the outside, into which the hollow bolts 17 or 18 can be inserted essentially with a precise fit.
- the base of the recesses 29 is rounded and has a radius which essentially corresponds to the outer radius of the hollow boices 17 and 18, the hollow bolts
- the individual parts of the chain link 13 are inserted into the turntable 23 by means of corresponding slides.
- the finished chain link is released by moving the round belt 30 away from the intermediate plate 26 in a delivery area so that it no longer exerts a holding force.
- a main difference of the joining head is that the positioning mandrels 1 and 2 or 3 and 4 each also have a frustoconical centering area 31 adjacent to the cylindrical projection 9.
- This frustoconical centering area 31 ensures in any case that the tabs 2 and 15 are aligned with the axes A and B regardless of the tolerance fluctuations of the openings 16 in the tabs 14 and 15.
- Another conical section can follow this.
- the length of the centering section 31 and the position of the stop surface 10 are chosen so that when the positioning mandrels 1 and 3 or 2 and 4 are moved towards one another a small joining stroke is already carried out, which attaches the tabs 14 and 15 to the outer surface of the hollow bolts or . starts.
- the positioning mandrels 1 to 4 are moved down simultaneously and evenly together with the punches 7 and 8 until the positioning domes 1 to 4 abut the end faces 21 and 22. Then only the punches 7 and 8 continue to move towards one another and end the joining stroke.
- the positioning mandrels 1 to 4 remain in their position as soon as the stop surfaces 10 press the end faces 21 and 22 with sufficient force. As a result, the hollow bolts 17 and 18 are centered since the forces are the same.
- the hollow bolts 17 and 18 can each have a reduced diameter region 32 at their end regions.
- a guide rail 33 is provided so that the tabs 14 and 15 cannot escape to the outside during feeding.
- An extension 34 is arranged on the stamp 7 and an extension 35 is arranged on the stamp 8.
- the extensions 34 and 35 have mutually associated stop surfaces 36 and 37 which move on the block 7 and 8 on the stroke of the punch and are in contact with one another. The stop surfaces 36 and 37 thus define the lowest stroke position of the punches 7 and 8, so that the distance between the tabs 14 and 15 is maintained.
- the extensions 34 and 35 can also be made adjustable.
- the punches 7 and 8 are also subjected to a uniformly uniform force, so that they align the plates 14 and 15 symmetrically to the main chain axis K A. It can also have only one stamp 7 or 8 an extension.
- the basic structure of a variant of the lifting mechanism for the positioning mandrels 1 and 3 or 2 and 4 and the punches 7 and 8 will now be described below with reference to FIG. 3.
- the lifting mechanism comprises a lever linkage 38 connected to the upper positioning mandrel 1 or 2 or upper punch 7 and a lower lever linkage 39 which is connected to the positioning mandrel 3 or 4 or the lower punch 8.
- the lever linkages 38 and 39 each comprise a pivot lever 41 which is arranged around a swivel joint 40 and which is connected via a compensating joint 42 to the corresponding positioning mandrel 1 to 4 or punch 7 or 8.
- the compensating joints 42 must convert the pivoting movement of the pivoting lever 41 into a pure linear movement. The resulting transverse forces and transverse motion components must be balanced.
- the pivot lever 41 is connected at its end facing away from the compensating joints 42 by means of a joint 43 to a push rod 44 which is adjustable in length.
- the push rod 44 is each connected via a joint 45 to a sliding bush 46 which is arranged so as to be able to move back and forth on a linear guide 47.
- the sliding bush is forcibly coupled to a cam 49 via a linkage 48.
- An overload safety device 50 is interposed, so that the scanning area 51 of the linkage 48 can be retracted further, but without moving the slide bushing 46 further. This is the case when the positioning mandrels 1 and 3 or 2 and 4 are in contact with the hollow bolts 17 and 18.
- the overload protection 50 engages.
- the force which is caused by the positioning mandrels 1 to 4 or stamp 7 and 8 is applied, adjust fairly precisely. Due to the symmetrical design of the lifting mechanism, the positioning mandrels 1 to 4 are moved towards each other evenly and uniformly and with the same force. The same applies to the upper and lower stamps 7 and 8.
- three of these lifting mechanisms for example, can work in parallel. The first lifting mechanism actuates the positioning mandrels 1 and 3, the second lifting mechanism the positioning mandrels 2 and 4 and the third lifting mechanism operates the punches 7 and 8.
- all four positioning mandrels 1 to 4 can be used can also be driven by a single lifting mechanism.
- the lifting mechanisms can be arranged so close to one another that the cam disks for the plunger lifting mechanism and the positioning mandrel lifting mechanism can be driven about the same axis of rotation by one and the same drive.
- FIG. 4 further exemplary embodiments of chain links to be produced are shown.
- an outer chain link 52 which can be joined by means of a similar joining head if the positioning mandrels 1 and 2 are modified accordingly and a prism guide is used.
- the hollow pin 17 of an inner chain link 13 is indicated. This is intended to show that when an outer chain link 52 is produced, the inner chain links 13 are interposed and the entire chain can thus be produced.
- Reference number b shows the symmetrical protrusion of the solid bolts 53 with which they protrude beyond the brackets 54.
- the duplex chain shown in FIG. 4 below can also be produced by means of an appropriately constructed joining head.
- the center piece 55 of the outer chain link must be preformed in a separate joining process.
- the link 56 is pushed exactly onto the main chain axis K A by means of a similar joining head. This is done by dispensing with the extensions 34 and 35 of the joining head, so that the punches 7 and 8 make an automatic centering in the middle.
- the inner chain links 13 are produced in the manner described above and the outer plates 57 are pressed on symmetrically in a final process by means of a joining head. The entire structure of the duplex chain is then fed to the joining head pre-positioned in a corresponding rotary table.
- the solid bolt 53 is stabilized by cylinder bore 5 or 6 in the punches 7 or 8.
- the reference number a shows that same distance from the outer surface of the middle plate 56 to the end face of the solid bolts 53. These are each equally far away from the main chain axis K A.
