摘要： A stamping punch of a punching apparatus for stamping comprises a grip member which is provided with crosspieces formed between long grooves on side walls of a rectangular parallelepiped, and a plurality of punch members which are formed integrally with the grip member. The respective punch members are arranged in parallel to one another. A plurality of long holes are defined on a punch holder. A large amount of adhesive is contained in the gap between joining surfaces when the grip members of the stamping punches are inserted and secured into the respective long holes. Accordingly, the positional accuracy of the punch member is improved, the accuracy of the hole defined through a workpiece is improved, and it is possible to eliminate any fear of occurrence of defect in shape. Further, the rigidity of the punch member can be improved, the stripper is prevented from application of unbalanced load, and the punch is easily exchangeable.

摘要翻译： 用于冲压的冲压装置的冲压冲头包括夹持构件，该夹紧构件设置有形成在长方体的侧壁上的长槽之间的挡条和与握持构件一体形成的多个冲头构件。 相应的冲头构件彼此平行地布置。 多个长孔被限定在冲头座上。 当冲压冲头的把持件插入并固定到各个长孔中时，接合表面之间的间隙中容纳大量粘合剂。 因此，提高了冲压构件的位置精度，提高了通过工件限定的孔的精度，并且可以消除对形状缺陷的发生的担心。 此外，可以提高冲压构件的刚性，防止剥离器施加不平衡载荷，并且冲头容易更换。
