Definitions
- the invention relates to a joining device for generating a clinching connection between a first Workpiece and a second workpiece with a stamp, which can be inserted from above into a recess in a die whose peripheral wall is stationary wall sections has, which is substantially parallel to the printing direction run.
- the invention further relates to a Enforcing process in which a first workpiece and a second workpiece with flat sections in at least partially overlapped and the first workpiece is pressed in from above is that it receives a cup-shaped shape, the presses into the second workpiece and this without Cutting deformed downwards, the shape of the first workpiece to predetermined circumferential areas limited undercut with the second Workpiece forms.
- the invention further relates to a clinching connection in which a first Workpiece has a formation that into a formation engages a second workpiece and with the second workpiece forms an undercut on predetermined peripheral areas is limited.
- the invention relates to a die according to claim 25.
- Such a joining device such a joining method, such a clinching connection and such a matrix are known from US-A-5 230 136 known.
- the die has a cylindrical shape Recess from which radial channels originate.
- On Stamp that has a slightly smaller diameter than that Has recess, created when lowering into two superimposed Workpieces are initially pot-shaped Forming the two workpieces, being in the area of Channels the material of the workpieces slightly outwards can be ousted. This can vary between the material of the upper workpiece and the material of the form a slight undercut in the lower workpiece, during the molding of the lower workpiece outside essentially vertical wall sections having.
- the two workpieces must have flat sections have, which at least partially overlap each other and lie parallel to each other.
- the first and the second workpiece the outer Workpieces are.
- every workpiece form an undercut with the next workpiece.
- DE-A-39 23 182 A1 shows a device for connection of plate-shaped components with a die that is made up of two parts at their lower end are held together with a tension spring.
- the die has a recess at its upper end, the widens conically downwards. If a stamp under Intermediate layer of two workpieces in the die is retracted, then a clinching connection creates an undercut across its entire circumference has an undercut between the first and the second workpiece and one Undercut on the outside. To remove the connected workpieces, it is therefore necessary that the two die parts can be pulled apart. Because this pull apart against the force of Spring occurs, there is a risk that the lower workpiece is scratched or damaged.
- GB-A-2 069 394 describes a method of connection of plate-shaped workpieces and a device to.
- the device has a die that passes through four resilient sections is formed which is circumferential are adjacent to each other and a recess surround. The recess widens conically downwards.
- In the recess is a counterpart to one Stamp arranged which, if a stamp is interposed two workpieces are inserted into the die is pushed down, against the Force of a spring. The movement of the counterpart hears shortly before the stamp reaches its maximum stroke Has. This will remove the two workpieces at the end of the Clinching process compressed so that material is radial is pushed out to make distinctions form. To remove the connected workpieces the sections forming the die are bent apart again become. Here too there is a risk that the bonded workpieces are scratched or on others Way to be damaged.
- DE-A-44 31 849 describes a clinching method and a clinching tool in which stamp and die elements on opposite and synchronous rotatable wheels are arranged. You can use it Generate push-through joints.
- the invention has for its object to simple Way to create durable joint connections.
- This task is accomplished by a joining device, by a clinching method, by a clinching connection and by a die according to claims 1, 20, 24 and 25 solved.
- the undercuts now provide a room in which the material of the two workpieces can flow into it. Because the material of the side facing the die through the material of the other workpiece is under pressure not only the material of the lower workpiece flows into the undercut area, but it also allows the material of the other workpiece follow, so that the first workpiece with the second Workpiece an undercut in the sense of a positive Entanglement forms. Usually would now with such an undercut, which also on the The die side can be seen, the removal of the workpiece from the matrix mean a certain problem.
- the levers preferably have a substantially flat surface Top on that is vertical in the working position to the print direction and in the same plane as the top of the die lies. Outside of the real one Forming, with the help of the clinching connection the workpiece is created in other words, a quasi continuous and flat surface. Outside the actual clinching connection there are no markings in the surfaces of the workpieces. Because the levers with their top form a plane that is perpendicular to the printing direction pressure peaks on the levers are avoided. The Rather, stress occurs relatively in the working position evenly, so that the levers are protected and accordingly have a relatively long service life. As long as the lever is not yet in the working position are the different pressure loads acceptable because here only relatively small counter forces act on the levers.
- Each lever is preferably designed as an angle lever.
- the pressure force required to move and hold the Lever used in the working position can then affect a larger area.
- the leverage ratios are cheaper here, so that you can also use a relatively weak lever Can absorb forces.
- the angle lever preferably has a short arm which the wall section is arranged, and a long one Arm on which there is a swivel axis.
- the Lever is designed like an L.
- At the The front of the short leg is the Wall section that forms part of the side wall of the recess the matrix forms.
- the forces acting here are connected to the via a relatively long lever arm Swivel axis forwarded. If you look at the closing forces has a lever arm of a similar length, on the outside of the short leg of the "L", then the desired results with relatively little effort Balance of power.
- the invention works satisfactorily when two opposite levers are provided. Here then several joint connections can be made relatively tight arrange adjacent. However, at least are preferred three levers distributed in the circumferential direction of the recess arranged. With three levers you can move in the circumferential direction a uniform and determined in all directions Ensure power distribution.
- the stationary wall sections preferably form at least 50% of the circumferential length of the recess.
- the undercut areas are seen in the circumferential direction relatively short. There are therefore only finger or radiating undercut areas that are vertical corresponding to the printing direction a relatively large May have depth.
- the die advantageously has one for each lever Protection against falling out. Has this fallout protection two advantages. On the one hand, when removing the Workpieces from the die no longer pay attention to that the levers remain in the die. These will rather captured by the fallout protection. On the other hand, you can now “over the die” Use head ", i.e. the stamp against the direction of gravity to move onto the die. So achieved you have greater flexibility in terms of Mounting position when operating the device.
- the fall protection is formed as a nose that radially towards points to the lever, the lever one with the nose cooperating notch.
- the nose preferably has one on its upper side Guide surface on which the lever moves slides.
- the nose is advantageously formed in an insert part. You can then use the nose, the levers to be held captive in the matrix. To replace the lever only requires the insert expand, but with a relatively small Effort is possible.
- the fall protection is designed as a pin through the die and the lever is guided and forms a pivot axis.
- the levers are captive Held die. It is only for mounting the levers required to insert the levers into the die and then insert the pen.
- the recess preferably has a bottom, the one at the top of one inserted into the die Bottom part is arranged.
- the bottom of the die the usually has a certain shape to a Flow of the materials of the work pieces into the corresponding ones Ensure marginal areas of the recess can is a wearing part.
- the flow of materials goes hand in hand with a not inconsiderable friction. Due to the possibility of the floor on a floor part order that is interchangeable, the maintenance and relative maintenance costs for the die kept small.
- the levers and the bottom like said, the main wear parts can form with simple measures can be replaced.
- the bottom part can be held stationary in the die.
- the same division can either be achieved mechanically, by punch and matrix equidistant to each other. But you can also by a suitable Motion control can be achieved.
- a Such a device can be a number of side by side Enforcing connections, so to speak generate continuously.
- the workpieces are between passed through the two carriers, the two Carriers have an intervention site on which a stamp engages in a die. At this point, then the clinching connection is created. By moving on of the workpiece and the carrier then comes the Stamp out of the die, and the next stamp enters the next die.
- At least one carrier as Wheel and the other carrier with a flat surface is trained.
- the wheel can then, so to speak, on the Roll off the surface, which can also be provided that the wheel has a stationary axis of rotation and the Carrier is moved past it.
- both carriers be designed as a wheel. On the surfaces of both wheels stamps or matrices are then provided, that engage one after the other.
- side by side Matrices differing from each other Lever arrangements on. Accordingly, they have side by side generated clinching connections from each other different orientations and / or shapes. This increases the strength of the connection. In particular, can one can achieve that the connection between the Workpieces in several directions have an increased load capacity having. It can be truss-like Generate structures that have high torsional rigidity of the joined parts.
- lever arrangements are arranged asymmetrically are, with the lever assemblies adjacent Recesses are twisted against each other.
- side-by-side push-through joints also an asymmetrical appearance, i.e. they are no longer point symmetrical to an axis that is perpendicular on the workpieces. If you now lie side by side Enforcement joints also against each other twisted, then the strength is different Directions improved.
- connection it has been found that the strength of the connection to a greater extent on the depth of the undercuts than on the length is dependent in the circumferential direction. So if you look at the undercuts limited to areas in the circumferential direction, these areas with a larger one Designed coverage in the undercut area, then the connection becomes firmer overall. You get there thus despite a one-step process and without Cutting share connection qualities, as they otherwise only by two-step processes or by enforcement can be achieved with cutting portion. Indeed are the compounds produced according to the invention also dynamic load.
- a closing force is preferably generated when pressed in on at least one tool part and when removing of the formed workpieces from the tool part one Opening force. This makes the process quasi self-controlling. No external funds are needed to to move the tool part into its working position or - when removing the workpieces - an opening to effect this tool part.
- the clinching connection can that the undercut depth, i.e. the depth of the positive interlocking, larger than before.
- the the material required for this can come from the areas in which there is no undercut.
- the shape of the active surfaces of the undercut forming levers can affect the flow properties the workpieces to be joined are optimized.
- the size and the location of the positive interlocking can through the choice of the predetermined circumferential ranges and the undercut depth can be optimized and defined.
- Fig. 1 shows a device 1 for generating a Clinching connection between a first workpiece 2 and a second workpiece 3.
- the device 1 has a stamp 4 and a die 5 on.
- the stamp 4 is here on a stamp carrier 6 attached.
- the stamp carrier 6 is with the help from drive units not shown the die 5 so movable that the punch 4 along a direction of movement 9 into a recess 7 (FIG. 3) the die 5 can retract.
- the recess 7 is here essentially hollow cylindrical, i.e. she has a approximately circular base. However, this is not necessarily. Also elliptical, oval or angular Shapes are possible.
- the die 5 has a recess 7 on, which is substantially hollow cylindrical is (Fig. 3).
- the recess 7 is accordingly in Circumferential direction limited by stationary wall sections 8, which run parallel to the direction of movement 9, i.e. corresponding to the representation of FIG. 1 vertically are directed.
- the recess is between the stationary wall sections 8 limited by movable wall sections 10, which are arranged on the inside of L-shaped levers 11 are.
- the wall sections 10 are in relation to the Direction of movement 9 inclined.
- the angle of inclination to Direction 9 is at least 15 °. They open up after towards the bottom and accordingly form an undercut 12 when the levers in the shown in Fig. 1 Working position.
- the levers 11 are in the die by means of pins 13 5 attached.
- the pins 13 form simultaneously Swivel axes for the levers 11.
- Each lever 11 has a pressure surface on its upper side 14 on, in the working position shown in Fig. 1 is flush with the top of the die 5.
- the leg that supports the wall section 10 lies with its underside 15 on a projection 16 the die 5.
- the lever 11 can not be swing further inside the die 5 than it is permitted by the projection 16.
- the recess 7 is down through a bottom 17th (Fig. 3) limited to the front of a floor support 18 is arranged.
- the floor bracket 18 is stationary mounted in the die 5 and in a central Hole 19. He is using the die 5 with the help a clamping ring 20 held. After loosening the clamping ring 20, the base support 18 can be removed from the die 5 to exchange it for another.
- the Floor 17 several levels 21, 22 and a rounded Tip 23 on.
- Fig. 2 From Fig. 2 it can be seen how the material of the two Workpieces 2, 3 flow. Because of the tip 23 and the Steps 21, 22 first of all material from the radial Center of the recess 7 displaced outwards. It but would already be due to the pressure of the stamp 4 a certain displacement compared to the die 5 result. Due to the special shape of the bottom 17 the flow of the material is supported radially outwards. The material of the workpiece 3, which is about the material the workpiece 2 is loaded, which in turn directly is acted upon by the stamp 4, where lever 11 are in the undercut 12, the is formed by the wall portion 10 of the lever. The material of the workpiece 2 follows and then forms the desired workpiece undercut the second workpiece 3 24 (Fig. 5).
- the cross section through such an undercut area 24 is shown on the left in FIG. 4.
- the connection shown there corresponds to the representation 2, but without tools.
- the pins 13 form a fall protection. Excessive opening of the lever 11 is caused by a Outer wall 26 of the die 5 prevents the lever 11 come to rest when they open their most Reach release position.
- the levers 11 remain in the release position until the next workpieces 2, 3 are brought to the plant. As soon as the required pressure is applied, fold the levers 11 back into their working position. This "closing" takes place due to the force relationships in any case before the workpieces are formed 2, 3 with the help of the stamp 4 begins.
- a rivet used as an auxiliary joining part is formed as a solid cylinder body be the circumferential in the area of its two axial ends Has beads or protrusions.
- the hereby conditional increase in diameter is in the range less tenths of a millimeter to about a millimeter.
- the rivet can have a certain conicity at the front ends exhibit. It is preferably at both ends equally trained, so that when you set the rivet does not have to pay attention to a predetermined orientation.
- the rivet is preferably in the non-movable Part of the device, i.e. usually on the side of the die. This makes feeding easier, because the rivet is then in a stationary guideway can be supplied.
- the second Stamp for example, lowered so far that it opens an opening to a feed path.
- This procedure is the formation of the clinching connection but not mandatory. You can use the rivet or a corresponding auxiliary joining part also from the side of the Feed the stamp, i.e. from above into the clinching connection deploy.
- Fig. 4 shows a modified embodiment in which Identical parts have been provided with the same reference symbols are.
- the outer wall 26 of the die has a nose 27 ', which engages in a notch 28 of the lever 11 when the Lever 11 assumes its release position.
- the intervention takes place a little earlier after one small outward movement of the lever 11 so that the lever 11 not even when pulling out the workpieces 2, 3 is also pulled out of the die 5. He stays rather hang on the nose 27 '.
- the lever 11 remains secure even when operating "overhead" in the die 5. As long as no workpieces 2, 3 on the die 11, the lever 11 through the nose 27 ', which in this case forms the fall protection, held. If the workpieces 2, 3 on the die 5 for System, then secure it against falling out the lever 11.
- Fig. 7 shows a third embodiment, in the same Parts are provided with the same reference numerals.
- To the 8 shows the device in a better understanding, if the stamp, the associated or joined Workpieces 2, 3 and the die are separated from each other are.
- the lever 11 is in solid lines in the working position and with dash-dotted lines Lines shown in the release position. from that it can be seen that the movement of the lever 11 is none pure swivel movement is more. Rather, the lever 11 becomes also raised a bit when changing position.
- the top of the nose 27 serves as Sliding surface on which a corresponding counter surface of the Notch 28 slides along. The lower end of the notch 28 however, remains in the release position at the bottom the nose 27 'hang and prevents further movement.
- the wall sections are 10 the lever 11 in the extended state, i.e. in the Release position vertical.
- the wall 26 is formed here as a separate part that can be removed and installed from the die 5. To the Replacing the lever 11, the wall 26 must be removed briefly become.
- 9 and 10 show that the movable wall section 10 'not necessarily formed by a flat surface have to be.
- the lever 11 is provided with a wall section 10 'which formed at its upper end by an inclined plane is, as in FIGS. 1, 4 and 7 also.
- Below this section there is a cavity 29 that one even greater space for the material to advance of the lower workpiece 3 is available. shown is the state of the transformation. Through a thin one Line 30 should clarify how far the material of the workpiece 3 still penetrate into the cavity 29 can.
- FIG. 10 shows an embodiment of a wall section 10 "in which a groove 31 is introduced, which is also a room available represents the material of the workpiece 3 and of course flow in accordance with the workpiece 2 can.
- Fig. 11 shows the process in four representations Demolding, i.e. the working section where the stamp is moved away from the die and the lever that Release the workpiece or the workpiece pair.
- 11a shows the starting point. It can be seen that the clinching connection has been established.
- the Lever 11 forms with its inclined wall section 10 an undercut into which the material of the lower Workpiece 3 has flowed into it.
- 11b shows that the stamp carrier 6 from the die 5 has lifted off. Because of a relatively large amount of friction between the punch 4 and the workpiece 2 takes the Stamp 4 the workpiece pair 2, 3 with.
- the undercut Area of the clinching connection comes but not yet free from the inclined wall 10, but also raises the lever 11, which is slightly outwards is pivoted or folded.
- the movement of the stamp carrier 6 continues until, as in Fig. 11c shows the clinching connection reaches the upper boundary edge of the wall section 10. Here, the lever 11 is the most outward pivoted.
- FIG. 12 shows a device where several stamps 4 on stamp carriers 6 are arranged, the stamp carrier 6 on a are arranged first wheel 50 which in the direction of a Arrow 51 can be rotated about an axis of rotation 52 can.
- the stamp carrier 6 and the stamp 4 are in this case below the pairing of workpieces 2, 3 arranged so that the resulting during the clinching Bulge on the top of the workpiece 3 arises.
- 12c shows the wheel 15 in plan view, partly in the cut.
- the stamp 4 on the surface are recognizable.
- the wheel 50 can be between two Clamping flanges 53, 54 are held, which in turn a shaft 55 are mounted, the shaft 55 relative is designed to withstand the necessary pressure forces to be able to record.
- the dies 5 are on the peripheral surface a second wheel 56 arranged in the direction an arrow 57 rotatable about an axis of rotation 58 is.
- the axis of rotation 58 is also by a relatively massive shaft 59 is formed, as shown in FIG. 12b can be seen.
- the peripheral speeds of the two wheels 50, 56 are the same, so that adjacent stamps 4 in succession can enter adjacent matrices 5. Thereby becomes a sequence of enforcement connections between the two workpieces 2, 3 generated.
- Fig. 12a From Fig. 12a it can be seen that the matrices 5 in modules are arranged on the peripheral surface of the Wheel 56 are attached. This simplifies production.
- the peripheral surface of the wheel 56 has one of the number the number of flats corresponding to the matrices 5 on.
- 13 shows a somewhat modified embodiment.
- the stamps 4 are still arranged in a wheel 50, that in the direction of arrow 51 around the axis 52 turns.
- the matrices 5 are in a carrier 60 arranged of a substantially flat surface 61 has. If the wheel 50 is in the direction of the Arrow 51 rotates, then the carrier 60 in the direction an arrow 62 moves synchronously, i.e. the peripheral speed of the wheel 50 agrees with the feed rate of the carrier 60. With this, too achieved that the individual stamp 4 in succession are inserted into the corresponding matrices 5.
