Definitions
- the invention is based on a method for a clinching connection of components with at least one plate, according to claim 1, or of a tool, according to independent claim 5, in particular for carrying out this method.
- the wall sections are formed on four pillars forming the die, these pillars providing the radial elasticity therein, and wherein there are gaps between the pillars, which can be obtained by absorbing the squeezed material and correspondingly more uncontrollably Design the same, adversely affect.
- these gaps are also provided in the bottom of the die, as a result of which the radial flow is impaired when the surface parts are squeezed.
- the floor is at least in its central area, closed and designed as a resilient piston, which again has the disadvantage that, in the event of a radial separation, displaced material can penetrate into the gaps formed between the said columns and this piston.
- two opposite wall sections are designed such that they yield resiliently, the deep-drawn and squashed surface parts engaging behind the plate at the flexible points, in contrast in the other transverse directions in which none flexible walls are present, just run smoothly in the direction of joining.
- the disadvantages here are that, on the one hand, crushed material can penetrate into the gaps formed as a result of the given separation of the opposite wall parts, and on the other hand, the non-engaging sections run slightly conically outwards, i. H. have the tendency to "unbuttoning". It was primarily important to the expert to obtain, at least in sections, the largest possible engagement of the squashed surface parts under the remaining sections of the plate and, on the other hand, to achieve such a connection point in one work step and this of course with sufficient strength.
- a device for a clinching method in which all four wall parts of the die are pressed radially outward against an annular spring during the deep-drawing or squeezing process (EP 0653255 AI).
- a sheet metal cage is arranged around the die, which, however, only has the task of receiving and guiding the die parts. This cage has no influence on the deep-drawing or squeezing process.
- the die bottom forms the end face of a piston which projects into the die and that the die wall parts are guided on the same step for the crimping process.
- an elevation known per se is present on the face of this piston, which of course has an influence on the squeezing process.
- the method according to the invention with the characterizing features of the main claim, as well as the tool according to the invention with the characterizing features of the secondary claims 2, 5 and 12, has the advantage over the fact that a controlled, clean deep-drawing process takes place in order to subsequently achieve a targeted radial crushing without crushed material unwanted in any gaps.
- the remaining wall sections advantageously displace the squeezed material in the direction of the displaceable wall sections, i.e. that there is an accumulation of displaced material from the deep-drawn and squeezed plate sections, in order to then ensure that these materials behind the plate are particularly strong due to the respective stop. In any case, by leaving parts of the wall sections standing, a larger engagement of the remaining surface sections is achieved.
- a rigid deformation of this path of the flexible wall parts then results in a cold deformation of the crushed material, which results in an increase in the strength of the joining point by approximately 30% compared to a non-cold-deformed crushed material.
- a connection point in only be carried out in one operation, ie the workpiece can be removed from the machine tool without an additional operation of the tool.
- the limitation of the radial path, seen over the circumference of the die is different, changeable or alternately large, so that different hardnesses can be achieved during cold forming.
- the stamp at least insofar as it dips into the die opening, remains in the form of a lost stamp, rivet-like and form-fitting in the penetration opening.
- this pushbutton-like connection point is virtually impossible to detach and, on the other hand, the possibility is achieved of additional connecting parts such as nuts, bolts or the like. to connect to the plate by forming the lost stamp either in the form of these connecting parts or as a counterpart to it.
- the particular advantage of the tool according to the invention is that, seen on the circumference of the working opening, between the movable jacket parts, in particular in one piece, fixed parts connected to the base part form a good and easy-to-control guide of the flexible jacket parts.
- the radially squeezed material is increasingly displaced into the areas of the resilient jacket parts, so that in the subsequent pressing process, a correspondingly high compression and thus hardness of the engaging surface parts can be achieved due to the stops.
- the stop which limits the path of the radially flexible jacket parts, is arranged fixedly (in one piece) on the base part of the die. This ensures in a simple manner that the corresponding strength can be achieved with only one operation.
- this stop can be adjustable or adjustable. It is important that this adjustment or adjustment option ensures that a quasi-connection is created between the stop and the base part. Normally, however, the die is replaced when the radial path is changed, for example in a different application. A change in the position of the stop can also be achieved with little effort.
- the base part can consist of one piece, into which grooves and bores for receiving the resilient jacket parts of the springs and the like. is arranged. This creates a compact tool that can be easily inserted into the machine tool.
- the base surface of the base part facing the working opening serves as a support and for the radial guidance of the casing parts. This primarily avoids gaps in the floor during the work process and corresponding displacement of the wall parts, into which material the displaced plate sections could penetrate, which would question targeted cold hardening and would also require several work steps to establish the connection point.
- the jacket parts are loaded radially in the direction of the working opening by spring force.
- this spring force can be designed differently. It can be designed as an internally engaging leaf spring, the free end of which engages the movable jacket parts, while the other end is fastened to the die body, or it can be formed by radially engaging coil springs or an annular spring encompassing the die parts. What is decisive here is less a radial force influencing the squeezing process than rather a resetting of the movable jacket parts after removal of the workpiece. It is also conceivable here for the single leaf springs to have connecting sections with one another, it being possible for these connecting sections to be received in recesses in the die.
- the mutually facing walls of two fixed jacket sections which are used for the radial guidance of a movable jacket part, are parallel to one another. This also ensures that as little displaced material as possible can get into any gaps in an uncontrolled manner.
- the stamp or the like is a lost stamp in the form of a rivet, a nut, a bolt. formed and remains positively and / or non-positively in the deep-drawn opening of the plate caused by him after completion of the enforcement.
- This composite material creates an additional strength of the connection, above all, because the deep-drawing opening is filled with a positive fit and it is no longer possible to untie the connection point.
- the rivet has a depression at least on one of its end faces, as a result of which the rivet material is better shaped when the rivet is pressed in, which not only leads to greater strength but also better appearance. Since the rivet material can be harder than the plate material, there is also an optimal material flow with the plate reaching behind appropriately through the crimped rivet material.
- the material of the lost stamp is harder than the plate material displaced by it during the joining process. This ensures that during the first part of the work process, namely the deep-drawing process, there is no deformation of the stamp, while in the subsequent squeezing process, which causes radial displacement and for which 80% of the force is used, the stamp material is also deformed, thereby reducing the stamp material Integrate stamps particularly positively. Of course, all of this is done in one operation.
- annular groove for receiving the displaced material is present in the radial lateral surface of the stamp, in order thereby to improve the anchoring of this lost stamp in the plate or in the deep-drawing opening.
- the stamp has an elevation on the end face facing the base part.
- an annular channel open at the end is arranged in the bottom surface of the base part.
- a centrally symmetrical elevation is present on the base surface of the base part.
- This survey does not exclude that, for example, an annular channel is arranged in the bottom surface in a manner symmetrical to it. Such an elevation forces the stamp material to spread out, this spreading usually taking place after the deep-drawing process.

- Fig. 6 shows a variant of the stamp with a curved end face
- Fig. 7 is a "lost stamp” in a perspective view with countersunk end faces and Fig. 8 is a partial section through a workpiece with "lost.”
- a tool according to the invention is shown, without the machine tool known per se in many different ways for pushing through metal sheets or connecting bolts, nuts or the like. with a plate, whereby in particular there is no punching through of the plate, but deep drawing with subsequent squeezing of the deep-drawn material.
- This tool is, on the one hand, a punch 1 driven by the machine tool which is arranged above two metal plates 2 and 3 to be connected to one another, and opposite a working opening 4 of a multi-part die 5.
- Die 1 and die 5 are used for their work in the die Machine tool used, the punch 1 being actuated in the direction of the double arrow V after inserting the metal plates 2 and 3 to carry out the clinching connection.
- the metal plates 2 and 3 are first deep-drawn into the working opening 4 and then squeezed radially outward on the bottom surface 9 of the working opening 4 after increasing the driving force of the stamp 1, the displaced material being first deep-drawn by the stamp 1 and then pinched surface parts of the metal plates 2 and 3 reach behind the remaining portions of the metal plates 2 and 3 in a known manner and thereby bring about the connection of the plates.
- the stamp can be designed as a lost stamp, ie it is, as not shown in more detail, the plates 2 and 3, as well as the working opening 4 and then pressed into the plates 2 and 3 by a press ram for the deep-drawing process.
- a lost stamp is either designed as a rivet, which primarily serves to unlatch the deep-drawn and squeezed plate portion, or it can be designed as a threaded bolt or a suitably designed nut, which can then be used, for example, to fasten other parts to only one plate serve.
- Decisive for the invention is how this stamp (deep-drawing pinch stamp, lost stamp in the form of rivet, bolt, nut or the like) deep-draws the plate material in the first working step in order to then squeeze it in the radial direction.
- the working opening 4 of the die 5 is delimited radially by four fixed wall sections 7 or four flexible jacket parts 8 and a bottom surface 9 on which the jacket parts 8 can be moved radially between the wall sections 7.
- the jacket parts 8 have a height which corresponds to the depth of the working opening 4.
- the jacket parts 8 are loaded by leaf springs 10 in the direction of the working opening 4.
- the path of these jacket parts 8 is limited by stops 11 according to the invention.
- the jacket parts 8 are pushed back into the starting position shown by the leaf springs 10, so that a new operation can begin. Because the jacket parts 8 can be displaced on the flat bottom surface 9 of the base part 6 on the side facing away from the stamp 1, high lifting forces can be absorbed by the jacket parts 8 without any disadvantage for the radial displacement. So that the jacket parts 8 receive a corresponding radial guidance, they point towards the fixed wall sections 7, towards those parallel sides 18.
- a connection point from the die side is shown on a section of the workpiece, with an annular bead 21 to be assigned to the ring channel 20 of the die and the pinched material accumulations 22 which, due to the facing sides of the displaceable jacket parts, in contrast to the annular bead 21, have straight boundary edges 23.
- a central region 24 of the base surface 9 can be curved in the lifting direction, for example in order to achieve an additional radial squeeze of the displaced plate sections.
- An annular channel 20 can be present around this central area 24, as shown in FIG. 3.
- FIG. 6 shows a variant of the stamp 1 in a side view, in which an elevation 13 is arranged on the end face 12, through which plate material is displaced radially outwards during squeezing, which of course leads to a thinning of the base of the connection point.
- an elevation 13 is arranged on the end face 12, through which plate material is displaced radially outwards during squeezing, which of course leads to a thinning of the base of the connection point.
- a spreading of the material is promoted during the squeezing process.
- FIGS. 7 and 8 show the use of “lost stamps” which, as described above, are processed after being inserted into the tool by means of a tool-bound press stamp. Such a “lost stamp” prevents the connection point from being unfastened.
- FIG. 7 shows a “lost punch” designed as a rivet 14, in which both end faces 15 are drawn inwards in a funnel shape. Due to this funnel-shaped design, especially during the squeezing process, the material flows apart, which in particular improves the grip behind the material that has stopped due to this deep-drawn and squeezed material. This effect is underpinned by the hardening according to the invention due to additional compressive forces.
- Fig. 8 it is shown in section how such a lost stamp 16 in the plates 2 and 3 after the pressing and Thermoforming process is embedded.
- the pot 17 caused by the rivet 16 in the plates 2 and 3 has a taper in the middle, which forms an extremely strong bond between the plates 2 and 3 due to the embedded lost stamp 16.
- the free end face of this lost stamp 16 lies in the plane of the outer surface of the plate 2.
