摘要:
A forming device for cup-shaped hollow bodies having a machine frame, a drive device, a workpiece rotary table for accommodating hollow bodies and a tool holder for accommodating processing tools, wherein the workpiece rotary table and the tool holder face one another and can be turned about a rotational axis in relation to one another and can be linearly moved in relation to one another along the rotational axis, and wherein the drive device comprises first drive means for providing a rotary step movement and second drive means for providing a cyclical linear movement between workpiece rotary table and tool holder to enable the hollow bodies to be formed by means of the processing tools in a plurality of consecutive processing steps. The second drive means has a stroke adjustment arrangement which is designed for adjusting a working stroke of the cyclical linear movement as a function of a control signal of a control device and/or for continuously variably adjusting the working stroke.

Crimping press comprises an anvil and a die which is movable towards and away from the anvil. The anvil is moved by a rotating shaft having a crank-type coupling to the die. The shaft is capable of limited movement in the direction of movement of the die towards the anvil. The shaft is supported against such movement by a yieldable shaft support that is calibrated to resiliently yield upon development of a predetermined reaction force in the die during the final stages of crimping. When a terminal is crimped onto a relatively small diameter wire, the shaft will not be moved at all or will be moved by only a slight amount if the predetermined force is reached. When a terminal is crimped onto a larger diameter wire, the predetermined reaction force will be developed before the die reaches the limit of its travel towards the anvil and the shaft will move away from the anvil to accommodate the remaining movement of the crank pin.

A shock absorbing device in a press is formed by having a telescopically sliding member fastened to the punch plate of the press and a stopper member fastened to the die plate of the press and placing an oil of high viscosity between the post and the outer cylinder of the telescopically sliding member. This shock absorbing device damps the unloading impact produced when the punch of the press collides with a workpiece and fractures it and, thereby, abates the noise generated from the press, the tool and the workpiece.
