Abstract: A method of producing and stacking components from individual layers which are punched, cut or the like out of a hardened material strip. According to the method, layers are removed from a hardened material strip, the removed layers are pressed back into the material strip and pressed out of the latter in a subsequent station (ii). They are then inserted into a stack magazine in which the individual layers are centered and assembled to form a component, the component then being removed from the stack magazine.

Abstract: The present invention relates to a process and a device for producing burr-free workpieces by blanking using a counterblanking tool. The counterblanking tool has an upper tool and a lower tool which include respectively an upper blanking die and a lower blanking die and an upper punch and a lower punch. The counterblanking tool further includes a ram plate which moves one of the upper and lower tools towards the other of the upper and lower tools. The ram plate moves in a continuous ram stroke during which a blanking strip from which a workpiece is to be blanked is clamped between the upper and the lower tool. During the initial portion of the blanking operation, the blanking dies remain in place while a first one of the punches, travels further and a second one of the punches travels back until a limit stop is reached. During this travel the first punch cuts partly into the blanking strip. After movement of the punches is stopped, one of the blanking dies travels against the limit stop and pushes the other of said blanking dies so that the dies slide along the punches and the second one of the punches cuts the workpiece out from the blanking strip. Thereafter the ram stroke is stopped and reversed so that the tools are separated and the workpiece is pushed out of the counterblanking tool.
Abstract translation: 本发明涉及一种用于通过使用反向冲压工具进行冲裁来生产无毛刺工件的方法和装置。 反铲工具具有上工具和下工具，分别包括上冲模和下冲模，上冲头和下冲头。 反铲工具还包括一个活塞板，该活塞板将上部和下部工具中的一个向另一个上部和下部工具移动。 冲压板在连续的冲程行程中移动，在该冲程行程中，将要冲切工件的冲切条夹紧在上部和下部工具之间。 在冲裁操作的初始部分期间，冲压模具保持原位，同时第一个冲头进一步行进，第二个冲头行进回到直到达到极限停止。 在这次旅行中，第一次冲压部分地进入到冲裁条中。 在冲头移动停止之后，其中一个冲切模具抵靠极限挡块移动，并推动另一个冲裁模具，使得模具沿着冲头滑动，并且第二个冲头将工件从冲切条切出。 此后，冲程行程被停止和反转，使得工具被分离并且工件被推出反向平移工具。

Abstract: In a method for the bending of workpieces by swivel bending jaws, the bent-off part is to assume a predetermined bending angle with respect to the workpiece, for this purpose, in a first bending operation, at least one corresponding leg is to be bent off from the workpiece by means of the swivel bending jaws. Then, the swivel bending jaws are released from the leg and a springback of the leg or the actual bending angle is determined by direct measurements and compared with a set bending angle. Subsequently, an agreement is established between set bending angle and actual bending angle by a renewed bending operation, by a bending-over.

Abstract: An arrangement for positioning components such as die or mold plates in shaping machinery, in which a positioning element is inserted into matching bores in the components to be positioned. The positioning element or device is provided with a cylindrical jacket around an axial bore and a continuous through-going slot. An elastic rod is inserted into the axial bore and is subjected to force from at least one end, for the purpose of increasing the thickness of the elastic rod and widening the cylindrical jacket so as to position the component. The components have, thereby, an elastic connection through the elastic rod. The continuous through-running slot provides elasticity by widening in accordance with the force that is applied.
