Definitions

• the invention is based on a method for connecting components such as plates, bolts, nuts and the like. with a plate forming a clinching connection according to the preamble of the main claim or a tool according to the preamble of the secondary claim 4.
• the so-called lost stamp used is either made of soft there is deformable material which is sufficiently hard to effect a press-in process through the plate or which has corresponding radial recesses into which the displaced plate material can be molded.
• the method according to the invention with the characterizing features of the main claim and the tool according to the invention with the characterizing features of claim 4 has the advantage that, with a high level of functional reliability, the production of the connection point over sections of the same results in a higher elastic connection, so that the final technical shear and head pull values are higher than at the connection point mentioned above.
• the elasticity of the connection point maintains the high working capacity of the method or the tool.
• the tool also has the advantage that the radially resiliently guided segments always return to their original position after the work step.
• Tools are known in which the radial boundary walls of the die consist of resilient sections (DE-OS 44 35 460 and DE-GM 297 00 868), however, with the disadvantage that all sections are resiliently mounted, as a result of which there is between the individual sections Remnants of the processed material can be deposited so that the sections no longer return to their original position, as a result of which the desired connection quality cannot be achieved.
• the distribution of the radial resistance with respect to the circumference of the die opening is centrally symmetrical. This achieves a uniform strength of the connection point.
• the clinching connection is supplemented by adding adhesives.
• the segment height corresponds to the depth of the blind opening, this ensures that the bottom of the blind opening is retained in its plane even for the enlarged blind opening by yielding the segments.
• the volume of the material to be displaced in the starting position (before the joining process) is somewhat larger than the volume of the bag opening minus the penetration volume of the die. The excess volume causes the segments to move radially.
• the segments can be moved against spring force.
• the spring can be designed in a wide variety of ways, the decisive factor being that the segments snap back into their starting position after the working stroke and back of the punch or removal of the connection point from the die opening.
• the segments are guided on a recess which receives the segments, which run in one plane with the bottom of the bag opening and have lateral guide bands which run in the radial direction of displacement of the segments. Any remnants of material are left in this work movement pushed away and ejected without the risk of being in a gap or the like. function-inhibiting deposit.
• the mutually opposite guide walls of the segments run parallel to one another on the rigid wall sections.
• leaf or bar springs arranged on the die serve as spring force. Apart from the fact that such springs are easy to attach and functionally reliable, they require only a small construction volume.
• the segments are guided in grooves in the die, as a result of which the radial dimensions can also be reduced.
• the springs at the end facing away from the segments are connected to one another in one piece via a connecting section, in the transition region between the connecting section and the springs there being an offset in the direction of the jacket parts.
• the connecting section is arranged in a dividing plane of the die which runs transversely to the drive direction, as a result of which it is possible for the connecting section to be firmly integrated into the die.
• this connecting section is cross-shaped or star-shaped, depending on how many springs are to be connected to one another.
• grooves for receiving the springs and / or the connecting section are provided in the longitudinal direction and / or on the end face in the parting plane.
• Fig. 3-5 variants of the embodiment.
• FIG. 1 an inventive tool is shown in an exploded view, namely a punch 1 which can be actuated according to the arrow III for its working stroke and which can press two plates 2 lying on top of one another into an opening 3 in a die 4.
• the die consists of fixed sections 5 of a die 6 and of segments 7 which can be pushed axially outwards and which are brought into the starting position shown by leaf springs 8 are pushed.
• the leaf springs 8 are fastened to the die 6 by means of screws 9 and are arranged in a longitudinal groove 11 of the die 6.
• the opening 3 is delimited at the bottom by a base 12 which is formed by the die 6.
• the segments 7 are guided radially displaceably between the fixed sections 5 of the die 6, for which purpose guide walls 13 on the fixed sections 5 of the die serve.
• the segments 7 slide on the bottom 12 of the bag opening 3. During this movement, the segments 7 are moved according to the evasion stroke IV.
• the clinching connection is made in that after the plates 2 have been placed on the die 6, corresponding surface parts are deep-drawn into the sack opening 3 down to the bottom 12 of the same by the stamp 1 in order to be subsequently squeezed, so that material radially outwards to the fixed sections 5 and the segments 7, which form the radial wall of the bag opening 3, are pushed. While the displaced material is retained in the fixed sections 5 of the die 4, the material lying in between is displaced against the displaceable segments 7, which yield, so that the material can flow. As described at the beginning, this creates a different structure of the connection point.
• FIG 3 shows a variant of the exemplary embodiment in which the leaf spring 8 'is welded to the die at 13 and to the segment 7 at 14. This provides a fixed connection, especially of segment 7 ', to the tool.
• FIG. 4 shows a second variant of this exemplary embodiment, in which a spring bar 15 is used instead of a leaf spring 8 ', which is inserted into corresponding bores 16 of the die 6 or 17 of the segment 7. While four segments 7 are provided in the object shown in FIG. 2, the variant according to FIG. 5 has only two such movable segments 7. Accordingly, the fixed sections 5 'of this die are made wider. Accordingly, the structure of the connection node is different.
