Definitions

the invention relates to a clinching die as part of a tool set, which also includes a stamp ..
the object of the invention is to provide a clinching die with the Preamble of claim 1 to create features that none which has disadvantages in the prior art, that is neither compromises in strength nor sensitive elastomer springs needs to demonstrate uncontrollable interventions in the construction of the Admits die.
the clinching die forms an element of one in a press insertable tool set, the other element Is a stamp that works together with the die.
Both elements or Tools each have a shank, for example in the form of the base 12, which can be received in an opening of a press-side base. Such openings are also called "nest”.
Hollow cylindrical nests and cylindrical shafts have the advantage that simply by turning, drilling, cylindrical grinding or other rotationally symmetrical Processes can be produced. But you have the disadvantage that the base provided with a cylindrical nest is relatively high Have space requirements and in particular "build”. There is also a tool change only possible by pulling the shaft out in the axial direction becomes; often this requires dismantling wipers and the like beforehand, so that no quick tool change is possible.
Hollow cuboid nests and cuboid shafts have the advantage that the nest is open to the front, i.e. across the working direction, so that the tool shank can also be removed to the front and thus a quick change is made possible.
the disadvantage is that the production of nests and shafts much more complex than with cylindrical designs is.
FIG. 2 it is a clinching die very similar to that shown in Figure 1 of the above-mentioned US-A-4,972,565 is. It comprises an anvil 10 with a base 12 and roof-like beveled support surfaces 14 on which (in the exemplary embodiment: two) spreading parts 16 are supported.
the expansion parts 16 are with upright, approximately crescent-shaped extensions 18 in plan view Mistake. If, by means of a stamp (not shown), material in enforced the space enclosed by the extensions 18 and between the stamp and the working surface 20 of the anvil 'compressed and thus spread , the expansion parts move sideways and give space free for the lateral flow of the material.
the evasive movement of the Spreading parts 16 also has a downward component due to the inclination of the support surfaces 14.
the shape of the blank can be seen from FIG. It includes a central section 30, which is when mounting on the flat tops of the Spreads 16 sets and holds them in contact with the support surfaces 14, but without clamping them.
the central section 30 is with a Provide breakthrough 32 through which the extensions 18 after assembly extend.
the breakthrough has two edge regions that are parallel to one another 34, the ends of which are connected by arcuate regions 36.
the straight edge regions 34 lie in a line with fold lines 38 .mu.m the tab portions 40 are angled so that they are in the finished Component run perpendicular to the central section.
“bend” is not to be understood here as the formation of a sharp edge, but a bending radius is intentionally provided; because the component is preferred made of spring steel would cause brittle fracture without a bending radius consist. This applies mutatis mutandis to others to be described Deformation of the blank.
the function of the tabs formed by the tab sections is Centering and guiding the expansion parts 16 during their expansion movement.
frost connects to one of the tab sections 42, while two short hoop sections 44 with the other tab section are connected.
the length of these frost sections is chosen so that their sum is somewhat larger than the size of the anvil '10 in Area of a groove 46, which is introduced into a partially cylindrical casing area is.
the last step in assembly is that the Hoop sections 42 and 44 are bent into this groove 46 and their each other overlapping ends joined locally e.g. spot welded will; these connection points 48 are, as can be seen in FIG. 1, positioned slightly inward of the tabs, but for joining still easily accessible.
Two further parallel fold lines 50 run perpendicular to the fold lines 38 and connect intermediate sections 52 to the central section 30.
Further fold lines 54 which run parallel to the fold lines 50 each an intermediate section with a reset element section 56 connect.
the latter are used in bending in a first Step around the fold lines 54 bent by an angle that is between 90 ° and is 180 °, preferably about 170 °.
a second step then the bends around the remaining fold lines, that way molded component is placed on the anvil provided with the expansion parts and attached as described above.
the intermediate sections and Reset element sections are dimensioned so that the free ends the latter after assembly resiliently on the opposite Fit the outer surfaces of the expansion parts.
the base 120 here intended for receiving a lower tool 122 with a shank 124.
the type of tool plays not matter; therefore an enforcement stamp is simply indicated, it but can also be an enforcement die.
the base is provided with a cuboid nest 126 and has in the rear wall 128 a threaded hole 130.
the shaft 124 is one with the threaded hole 130 aligned through hole 132 for receiving a countersunk screw 134 provided.
the screw 134 holds the tool in the nest, however, does not transmit pressing forces; these are rather from the face 136 of the tool in the foot 138 of the base. How in particular 8, the shaft 124 has line contact with the side walls 140 of the base. But since the rear flattening 142 of the shaft lies snugly against the rear wall 128 and the shaft is just as snug sits on the base 138 of the base, only define the side walls still the side position of the tool and need (almost) none Transfer forces.
the arrows indicate the direction in which the individual parts are facing relocated to carry out the installation of the tool.
a step 150 is formed on the bottom of the partially cylindrical nest which the inner or rear flatten 142 creates when the tool 122 is turned into the correct position. It can be seen that the shaft 124 introduced above the stage 150 serving as an anti-rotation device is rotated and then down to the base 138 of the base 120 is pushed. Instead, it could also be on the bottom of the shaft 124 a recess 152 can be provided in the form of a groove, which has space for the level 150 offers; this is indicated by dashed lines in FIGS. 13 and 13. The fixing of the tool in the base could with this base type are also carried out as described above in FIGS. 5 to 12. In any case, made possible the front accessibility of the nest a quick tool change, as discussed above.
Grooves are in the partially cylindrical circumferential sections of the shaft 124 154 introduced, for example screwed in, and the base 120 has Threaded hole 130 is offset from axis 156 of the tool shank such that the conical head 158 of the screw 134 in the one groove 154 engages and secures the tool 122 in the base 120.
the dimensions are preferably chosen so that the screw head when tightening exerts a downward force component on the base that presses this firmly against the base 138 of the base. It is understood that not only for one, but for both grooves 154 each with a threaded hole Screw 134 can be provided.
the grooves 154 are included shown approximately semicircular cross section, but also offers a triangular cross section to indicate the downward component of the Initiate tension more evenly.
the geometry of the screw head does not necessarily have to be conical, but adheres to the geometry of the groove cross-sectional shape customized.
the shaft 124 could also have a cross-sectional shape, which in the is essentially rectangular - adapted to hollow cuboid nests -, in which, however, the corner areas are cylindrical, adapted to hollow cylindrical ones Nests.
