"Device for the mutual fastening of overlapping sheets ^M

Claimed priority of the patent application S.H. 275 on July 28, 1972 in the USA

The present invention relates to a device for mutually fastening sheets of deformable metal or other material lying one on top of the other, which without breaking or tearing, is ductile or flexible or flows under load and which permanently maintains the respective deformation. In some cases, a layer or film made of another material can also lie between the sheets to be fastened.

In the earlier filed U.S. patent application S.N. 146 are «in process and a device for fastening superimposed sheets described. In the device described is a double-acting press with two

independently operable plungers used »by which one a hollow, cylindrical cutting and forming die and the other a planing or flattening die wearing. These tools work together with a fixed punch attached to the lower part of the press. In the present patent application, improvements to the device are described in the previously filed patent application »

The invention is intended for the "double-acting press" described in the aforementioned US patent application, an adjustable support device for the cutting and forming die as well as create for the leveling or Abilach stamp, so that for sheets of different thicknesses to be fastened to one another and a corresponding adjustment is possible if the die and / or the punch are worn.

In particular, adjusting means are to be created, so that the upper sheet (the shift of the shifted cutout by the die and the fixed die j not sit which comes after moving down grader or Abflachsteapel in system until the lower sheet of the displaced clips of the die moving upwards has been released so that the lower sheet of the displaced cutout can spread while the upper sheet is still held by the die «

In order to thus make two or more sheets lying one on top of the other Metal or another deformable material by partially punching and deforming cutouts from the sheets To attach to each other is a fixed punch and form punch in a double-acting press ait two Independently actuated plungers used · For moving sections of the stacked Sheet metal, one of the plungers carries a hollow, cylindrical one

Under the cutting and forming die 70 in the lower part 90 A punching and forming die 80 is arranged in the press. The punching die 80 has cutting edges for punching and recessed areas for shaping. The punch 80 can match the stamp in the aforementioned U.S. patent application S.N. 146 639 and can be adjusted axially as shown there let. The punching and forming die 80 is surrounded by a wiper or a spring part 81 which is preferably made of urethane material.

In the mutually aligned holes of the die holder 50 and die 70, the extended shank of a grader or Abflachstempels 92 is arranged · As can be seen from Figures 1 to 3 is of the grader or Abilachstempel 92 is _t supported by a punch holder 292, which at a central plunger or slide 392 carried by a bolt 42 and an adjustable part 44. The adjustable part 44 is adjustably supported by means of a screw bolt 45 which in turn is carried by a plate 46 which is secured by means of screws 47 (see Fig. Figure 2) is attached to the underside of the middle crank 32. The plate 46 has a downwardly protruding portion 146 with a pair of slots 48 formed therein which receive screws 49. In this way, the part 44 is secured against twisting. The screw bolt 45 has a widened head part 145 which is held in a recess in the plate 46. The screw bolt 45 also has a fixed, larger, round part 245 with bores for a bolt which can come into engagement, for example by turning the bolt, in order to rotate the screw bolt 45 to thereby raise or lower the part 44, which then causes the Position of the head 192 of the leveling or flattening punch 92 with respect to the punching or forming punch 80 can be adjusted. Of course, the screws 49 must be loosened for this setting.
