Abstract: A die for a tool set includes at least one punch and a die which defines a cavity for effecting joining. The die comprises an anvil opposite the punch. Die segments adjoin the said anvil and define the cavity in the circumferential direction. When the punch is being fed in the direction of the anvil, the segments execute a yielding movement transversely to the punch feed direction.

Abstract: The invention relates to a die for a tool set for the mechanical joining of sheets resting one on top of the other in a planar manner by forming with at least one punch and a die which defines a cavity into which joining is effected, and the die comprises an anvil opposite the punch and die segments which adjoin the said anvil, define the cavity in the circumferential direction and, when the punch is being fed in the direction of the anvil, execute a yielding movement transversely to the punch feed direction, for which purpose the die segments are arranged on a supporting surface in such a way that they can be displaced outwards against spring preloading, and the die is encased circumferentially by a die sleeve, the die sleeve, in the circumferential direction, following a division into die segments, having individual segment guides which form guideways extending through the die sleeve, and in which the die segments are guided in such a way as to be displaceable outwards as sliding pieces formed with an exten

Abstract: The invention relates to an apparatus for the mechanical machining of workpieces, having two tong members in the form of two-armed levers which are mounted rotatably with respect to each other and to whose working ends tool instruments can be fastened, the one tong lever having a fixed tong handle and accommodating a driving piston whose ram can be moved over a selectable advancing stroke path towards a driving end of the other tong member, as a result of which the working end of the other tong member can be moved onto the working end of the one tong member counter to a restoring spring in order to execute a working stroke, the other tong member having, as the driving end, a pivotably coupled spacer which can be orientated towards the ram with a tension spring, which holds the spacer outside an advancing stroke path of the ram, acting on the free end of the said spacer, and on which spacer at least one driver element is provided which is engaged with a pivotable actuating element which pivots the spacer count

Abstract: A tool set for clinch-connecting superposed sheet materials is disclosed, the tool set comprising a punch and a die. The die includes an anvil and shaping elements displaceably disposed on the anvil. All shaping elements are positioned by one single metallic member mounted on the die such that it is destroyed upon removal. Also, a novel socket for mounting the tool set on a press is disclosed.
