摘要： A punch machining device for a plate is formed of a vertically movable upper die including a horizontally arranged punch holder with a large number of punches for punching the plate, a stripper plate vertically movably situated under the punch holder and having holes to allow the punches to pass therethrough and a returning device for urging the stripper plate in a direction away from the punch holder, and a lower die situated under the stripper plate to form a passage for the plate to be punched between the lower die and the stripper plate. The device further includes pressing heads installed on the punch holder for the respective punches, and pressing head driving devices attached to the respective pressing heads. Each pressing head driving device operates to locate a head part of the pressing head for immovably holding the punch against the punch holder or to locate a stepped part of the pressing head for allowing the punch to slide upwardly through the punch holder to thereby selectively activate the punch for making a hole in the plate. A control device may be installed for actuating the pressing head driving device in compliance with punching pattern so that desired pattern of holes is made in the plate in the punching operation.

摘要翻译： 一种用于板材的冲压加工装置由可垂直移动的上模具形成，该上模包括具有大量用于冲压板的冲头的水平布置的冲头保持器，可垂直移动地位于冲头保持器下方的具有孔的脱模板， 通过其以及用于沿远离冲头保持器的方向推动剥离板的返回装置，以及位于剥离板下方的下模，以形成用于在下模与剥离板之间冲压该板的通道。 该装置还包括安装在用于各个冲头的冲头保持器上的压头和附接到各压紧头的按压头驱动装置。 每个按压头驱动装置用于定位按压头的头部，用于将冲头固定地保持在冲头保持器上，或者定位压头的阶梯部分，以允许冲头向上滑过冲头保持器，从而选择性地启动 打孔在板上打孔。 可以安装控制装置，用于按照冲压图案致动压头驱动装置，使得在冲压操作中在板中形成所需的孔图案。
