    摘要： The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

    摘要： 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). Thereby, the spring-damper element (2) is designed in such a way that the fluid pressure or the pressure difference, respectively, at which the overload valve (7) opens can be adjusted when the spring-damper element (2) is installed as intended. With such spring-damper elements according to the invention, it becomes possible to create a mounting arrangement for a punching press, the damping characteristics of which can be adjusted without significant effort, such that a variable operation of the press in wide ranges becomes possible while keeping the ground loading to a minimum in each case.

    摘要： Die cutter holding and lifting systems, apparatuses, and methods for use with custom and commercially available die cutters. According to some examples, a system includes a base, a separation assembly, and an actuation assembly. A separation assembly can be coupled to the die cutter, and the die cutter in combination with the separation assembly can be coupled to the base, such that the actuation assembly can be utilized to cause a separation of die plates of the die cutter for increased productivity in cutting, stamping, or pressing operations involving die cutters.

    摘要： In a sheet processing method for sheets of paper or cardboard, a sheet for processing is, in the processing station, firstly brought to a standstill and then set down, whereas the processed sheet is, in the output station, set down from a moving state. A punching or stamping machine has an input station, a processing station and an output station arranged one behind the other in a sheet transport path, and a sheet gripping device which is designed to set down a sheet for processing in the processing station when the sheet gripping device has come to a standstill in a second reversal position, and to set down a processed sheet in the output station as the sheet gripping device approaches the second reversal position.
