  • Patent number: 12296552
    Abstract: The invention relates to a punch press with a crank or eccentric drive, including a crank or eccentric shaft (1a, 1b) and active connecting rods (9a, 9b) for generating the stroke movement of the press ram (13). Furthermore, the punch press includes balancing weights (2a, 2b) for balancing the vertical and horizontal mass forces and is designed in such a way that the horizontal drive movements required for the horizontal mass balancing are tapped directly at the crank or eccentric shaft (1a, 1b), preferably laterally at the crank or eccentric shaft (1a, 1b).

  • Patent number: 11976702
    Abstract: The invention relates to a spring-damper element (2) for mounting a punching press (1), with a hydraulic damper unit (3) with a first fluid chamber (4) and a second fluid chamber (5), wherein, in the intended operation, a hydraulic fluid is displaced from the first fluid chamber (4) via a throttle point (6) into the second fluid chamber (5) when the spring-damper element (2) is compressed. The damper unit further comprises an overload valve (7) arranged between the first fluid chamber (4) and the second fluid chamber (5), which overload valve opens when a specific fluid pressure is reached in the first fluid chamber (4) or when a specific pressure difference is reached between the first fluid chamber (4) and the second fluid chamber (5) and releases a bypass (8) via which hydraulic fluid then flows from the first fluid chamber (4) into the second fluid chamber (5) bypassing the throttle point (6).

  • Publication number: 20210291474
    Abstract: The invention relates to a method for operating a stamping press (1) with a ram (2) which acts against a bolster plate (3), in particular a fixed bolster plate (3), and whose ram position relative to the bolster plate (3) can be adjusted in the intended use, wherein the ram (2) carries a first die part (4) and the bolster plate (3) carries a second die part (5), wherein the two die parts (4, 5) provide associated stop faces (6a, 7a) which, when the die is completely closed, form one or more fixed stops within the die for limiting the closing dimension of the die (4, 5). In accordance with a first method according to the invention, the distance (a, a1, a2, a3) between the two die parts (4, 5) or a parameter (b1, b2, b3, c) representing said distance is monitored at a certain point (P1, P2, P3) of the ram movement in which the die (4, 5) is not fully closed, and the ram movement is changed as a function of the monitoring result.

  • Patent number: 8739595
    Abstract: The invention relates to a punching press with a clamping plate (27) and with a press ram (1) which lies opposite the upper side of the clamping plate (27) and operates towards the clamping plate (27) and is moveable up and down via four tension columns (2) by means of a crank drive arranged below the belt movement plane (X) of the punching press. The press ram (1) is guided exclusively via the tension columns (2) which, in turn, are guided in inclination-tolerant guides (3) in the belt movement plane (X) in such a manner that the press ram (1) and the tension columns (2) can be positioned obliquely as a consequence of differing longitudinal expansion of the tension columns (2) under an eccentric load by the tension columns (2) being inclined about axes of inclination running in the region of the belt movement plane (X) of the punching press.

  • Patent number: 6834477
    Abstract: A string (12) of pocketed coil springs (14) is formed by inserting compressed springs between upper and lower plies of a folded, preferably thermally weldable fabric (16). The springs are maintaned in a compressed configuration while a longitudinal seam (54) joins the free edges of the thermally welded fabric (16) together. Subsequently, the compressed springs (14) are allowed to relax into an expanded configuration after which a transverse seam (80) is formed in the fabric (16) between the adjacent springs (14) thereby encapsulating each spring (14) within a fabric pocket (86). The string (12) of pocketed coil springs (14) is advantageously formed without the need for reorienting the springs (14) after being inserted between the plies (24,26) of the fabric (16) and thereby avoiding the disadvantages and complications associated with turning or reorienting the pocketed coil spring (14).
