Abstract (en)
[origin: CA2814928A1] In a press (1) having a bottom drive, a plunger (1.1) executing a stroke (h) and accommodating at least one upper tool part (1.2), tie rods (2.1.2) acting on the plunger (1.1) which in each case form a drive train (2.1.4) of a drive device (2) having a motor or servomotor (2.1.1), and a lower tool part (3.2) arranged on a sub-structure (3), in which the plunger (1.1) with the upper tool part (1.2) acts on the workpiece (5) to be processed, the effective forces act in a differentiated manner and in a greater effective range if, by means of an open-loop and closed-loop control device (4), values from operating states in the system of the press (1) are recorded during the processing of the workpiece (5) and are evaluated in accordance with the function (Formula (I)) to form data, and the movement of the plunger is used for x, so that the press (1) can be operated under open-loop or closed-loop control in accordance with a force system required for the workpiece (5).
