发明名称 METHOD AND DEVICE FOR PRODUCING PRECISION BLANKINGS FROM A MATERIAL STRIP
摘要 The incomplete compound die cut along the circumference of the fine-blanked part is carried out with a specially shaped cutting edge of cutting punch (11) and/or cutting plate (5) such that the fine-blanked part (1) initially remains bonded to at least one partial connecting part on the material strip (2), either on the upper or lower plane at a level relative to the material strip. It is then moved together with the material strip in the running direction of the strip to a subsequent removal stage (ejector), in which the fine-blanked part and material strip are separated from each other perpendicular to the running direction of the material strip towards the bottom by braking the connecting part without a vertical shear force and without pressing, wherein the removed fine-blanked part (1) is fed through a chute (9) in the cutting plate.
