摘要： A method and a press are proposed for an energy-efficient drive of a press (1) with a bottom drive, in which a drive device (2) disposed in a bottom section (3), a plunger (1.1) executing a stroke (H) and receiving an upper tool part (1.2) with at least one acting tie rod (2.1.2) of a drive train (2.1) are provided and the upper tool part (2.1) corresponding to a bottom tool part (3.2) disposed in the bottom section (3) machines or forms a work piece (5). The drive device (2) is operated by at least one motor (2.1.1) and by way of a control and regulation device (4) connecting the motor (2.1.1) and the drive train (2.1). Each drive train (2.1) can be operated by its own motor (2.1.1). When using a drawing device with a holder (3.3.1), it is operated in the change and during at least a partial path of the respective stroke (H) by the drive train (2.1) while observing a shaft-type free space (3.2) provided in the bottom section (3) in a coupled or decoupled manner by a releasable rotatory or translational active connection.

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-cum-slide cushion device selectively opens and closes a flow channel between a hydraulic pump/motor driven by a servo motor, and hydraulic cylinders that generate slide cushion force, or a flow channel between the hydraulic pump/motor, and hydraulic cylinders that generate die cushion force, by switching a selector valve. Before applying the slide cushion force is started, the servo motor is controlled to allow the hydraulic cylinders to generate required slide cushion force through a check valve. While the slide cushion force is applied, hydraulic circuits, each of which includes a logic valve, control pressure of the hydraulic cylinders, and hydraulic circuits, each of which includes the servo motor, control die cushion pressure of the hydraulic cylinders.

摘要： Provided is a press apparatus which ensures high production efficiency and has less chances of breakdown. Specifically, the press apparatus has a base placed on a floor, and a platform arranged over the base to face the base and move up and down. A lower die, on which a steel plate is to be placed, is fixed to the base. An upper die is fixed to the platform to press the plate against the lower die and turn it into an initially formed product through a downward movement of the platform, and to pressure-hold the initially formed product with the lower die. A machining die is supported on the platform to move up and down to machine the initially formed product and form a final product by moving down while pressure-holding the initially formed product.

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.
