摘要： Punch apparatus for simultaneously punching concentric but unequal sized holes in two adjacent material sheets. The punch apparatus is made up of three members: a punch, a die block, and an intermediate piece. The intermediate piece coacts with the punch and performs the function of a die block, and the intermediate piece also coacts with the die block to perform the function of a punch. The first material sheet is located intermediate the punch and intermediate piece, and the second sheet of material is located intermediate the intermediate piece and the die block. Downward movement of the punch, in cooperation with the intermediate piece, punches one hole in the sheet between the punch and intermediate piece. Downward movement of the punch also causes the intermediate piece to move downward and punch a hole in the second sheet of material, concentric with the first hole, but of a different diameter. Flexible loosening rings can be used to facilitate removal of the punched out material. In addition to the loosening rings or alternatively in lieu thereof, the punch and die block are provided with air passages to communicate with an air supply to remove the punched out material.
摘要翻译：冲孔装置，用于同时冲压两个相邻材料片中的同心但不相等的孔。打孔装置由三个部件组成：冲头，模具块和中间件。中间件与冲头共同作用并执行模具的功能，并且中间件也与模具块共同作用以实现冲头的功能。第一材料片位于冲头和中间件之间，第二材料片位于中间件和模具块之间。冲头的下移与中间件配合，冲压冲头和中间件之间的板中的一个孔。冲头的向下运动也使得中间件向下移动并在与第一孔同心但是具有不同直径的第二片材料中冲孔。可以使用柔性松动环来促进冲压材料的移除。除了松动环或替代地替代地，冲头和模具块设置有空气通道以与空气供应连通以移除冲压出的材料。
