摘要： A cylinder holder for a hydroforming device has a substantially cuboid cylinder holder body with a hydraulic cylinder seat to which a hydraulic cylinder can be fixed. The hydraulic cylinder is configured to supply a hydroforming fluid to a workpiece to be shaped. The cylinder holder further includes a base plate to which the cylinder holder body is fixed at a predetermined angle with an anti-rotation lock unit.

摘要： The invention relates to a drawing press (10) having a first ram (17) and a second ram (18). The first ram (17) is moved in a working direction (A) by an electromotive first ram drive (25) and the second ram (18) by an electromotive second ram drive. The drawing press (10) also has a coupling means (35) which can be switched between an uncoupling state and a coupling state. In the uncoupling state, the two rams (17), (18) can move independently of one another in the working direction (A). In the coupling state, the coupling means (35) ensures that a relative movement between the two rams (17, 18) is prevented. The drawing press (10) can therefore be operated as a single-acting or double -acting press.
摘要翻译：本发明涉及一种具有第一压脚（17）和第二压头（18）的拉拔压机（10）。第一柱塞（17）通过电动第一柱塞驱动器（25）沿着工作方向（A）移动，第二压头（18）通过电动第二压头驱动器移动。拉拔压机（10）还具有能够在非耦合状态和耦合状态之间切换的联接装置（35）。在非耦合状态下，两个公柱（17），（18）可以在工作方向（A）上彼此独立地移动。在联接状态下，联接装置（35）确保防止了两个公柱（17,18）之间的相对移动。因此，拉伸压机（10）可以作为单作用或双重压力机操作。

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).
摘要翻译：本发明涉及一种用于从盆形坯料（37）制造罐体的装置（20）和方法。为此，坯件（37）插入到底部工具部件（45）中。坯料（37）被夹紧在下部工具部件（45）的下支架（23）和对置支撑表面（47）之间。为了控制确定向下夹持器（23）的位置和/或位置变化的位置值α，提供驱动装置（22）。驱动装置根据预定的过程来控制位置值，以便将下压板（23）移动到夹紧位置或从夹紧位置EP移动。一旦向下夹持器（23）到达其夹紧位置EP，驱动单元（22）根据预定过程控制力值，该预定过程确定由向下夹持器（23）施加到空白（37）。这优选地通过将电动机电流I调节到期望值IE（t）的预定过程。
