摘要： The invention concerns an arrangement (20) and a method for the manufacture of can bodies from pot-shaped blanks (37). To this end, the blank (37) is inserted into a bottom tool part (45). The blank (37) is clamped between a downholder (23) and a counter support surface (47) of the lower tool part (45). For controlling a position value α determining the position and/or position change of the downholder (23), a drive arrangement (22) is provided. The drive arrangement controls the position value in accordance with a predetermined course, so as to move the downholder (23) into the clamping position or out of the clamping position EP. As soon as the downholder (23) reaches its clamping position EP, the drive unit (22) controls a force value in accordance with a predetermined course which determines the clamping force F(t) which is applied by the downholder (23) to the blank (37). This occurs preferably by an adjustment of the motor current I to a predetermined course of the desired value IE(t).

摘要： The drawing press (10) according to the invention has for driving its ram (15) a directionally reversing gear mechanism (22, 54), for example a coupling gear mechanism, and at least one servomotor (23). The servomotor (23) passes through the reversal point (Ut) of the ram movement, which is predetermined by the kinematics of the coupling gear mechanism, for example the extended position of an eccentric drive. During the closing of the die (18), that is to say during a press stroke, the servomotor (23) is activated in such a way that it first passes through this reversal point (Ut), then stops, reverses and then passes through it once again, in order to open the die (18) again. Consequently, the braking to a standstill and re-acceleration of the servomotor for the upper ram (15) takes place while the actual drawing operation is still or already being performed, i.e. during the forming of the metal blank, which significantly reduces the cycle time.

摘要： A die cushion pad 13 is divided into four small pads 15 and a large pad 16. With this arrangement, a load applied to an action point of each of the small pads 15 can be equalized by the large pad 16, and an overturning moment arising between the action point and a reaction force point that equates the center of the small pad 15 can be canceled, thereby preventing flexure of the small pad 15. Accordingly, since flexure of the cushion pin and the like can be prevented, there is no risk that the cushion pin is frictioned against the penetrating hole of a bolster, and the lifting operation can be smoothly performed, whereby a higher-accuracy pressing forming operation can be realized.
