摘要： In a method of cutting high-tensile workpieces, in particular sheet metals of martensite steel, the workpiece is subjected to a bending stress prior and during a shearing process. The bending stress causes a substantial component of a tensile force transverse to a desired cutting contour. Tensile stresses are superimposed to the shearing stresses, which favor the beginning of the workpiece separation. The bending stress is preferably selected so that the resulting tensile stress exists at a side facing the cutting tool.

摘要： A press with a press drive for moving a plunger in stroke direction (H). The press drive comprises two electric drive motors which are controllable independently of each other. The two drive motors are connected to the plunger via a drive unit. A control arrangement is provided for controlling the two drive motors. The control arrangement includes a characteristic plunger curve (K) which determines the plunger positions and/or the plunger movement and/or the plunger force dependent on time or dependent on a so-called virtual press angle. In addition, the control arrangement includes an additional condition which is independent of the characteristic plunger curve (K). Via the additional condition the operation of the press drive, for example, in an optimum operating range and/or a low-wear lubrication state of the support bearings of the drive unit can be ensured.

摘要： To increase the cutting quality and to improve the operation of a press, in particular in punching high-strength martensitic materials or when punching thick sheet metal, a sheet metal holding device is provided for securely clamping the respective workpiece during the punching operation. The clamping force is increased to 40% or more of the ram force. The force exerted by the sheet metal holding device during the penetration of the workpiece can be further increased. The increase in the clamping force preferably takes place in a controlled manner as a function of the press angle.

摘要： The drawing press according to the invention includes a support structure for supporting a metal sheet holder which is part of a tool and supported on the press frame via the support structure. The metal sheet holder is assigned a plunger with a die tool, whereas the plunger is moved by means of a plunger drive which includes a blocking position. The blocking position is obtained, for example, by a drive which, in the blocking position does not transmit any movement of the drive output to the driving servomotor. This can be achieved, for example, by an eccentric drive in the stretched position thereof. For performing the actual drawing stroke, the stamping tool is vertically movably supported. A carriage is raised or lowered by the press table by means of a table drive. As table drive, preferably a servomotor with a non-linear drive, such as an eccentric drive is used.

摘要： In an overload safety device in a press, having a driving device with a drive shaft, a slide carrying out an oscillating movement and a connecting rod which connects the drive shaft with the slide and has a large and a small eye, the connecting rod is provided with a pressure element disposed displaceably in the longitudinal direction of the connecting rod. The pressure element acts at least indirectly upon a fluid such that, when a certain force acts upon the connecting rod, a pressure increase occurs in the fluid. The fluid is guided to a pressure limiting valve which, when a predetermined pressure is exceeded, causes an interruption of the slide movement.
