钢窗构件3205型钢落榫如图1所示。该构件采用制造钢窗中柱的专用型钢制造。原准备分两步进行冲制,即先按要求长度断料,然后分头进行冲榫。这样模具设计简单,制造方便,但对价格较贵的3205型钢浪费较大,工作效率也低,另外型材较长,在两次冲裁时都需要翻动型钢,增加了工人的劳动强度,故弃之重选。后决定采用一冲裁新工艺,即断料、冲榫同时进行。冲头形状对称设置,冲床一次动作,能同时冲出两根中柱的一端榫形。经试生产,效果不错。 1.模具的设计采取断料、冲榫同时进行的新工艺,一次能冲出两个榫头,效率提高一倍,且凸模
Steel window member 3205 steel dowel shown in Figure 1. The component is made of special steel for the manufacture of steel window columns. The original preparation in two steps for punching, that is, the length of the first cut-off required length, and then separately punch tenon. This mold design is simple, easy to manufacture, but the more expensive 3205 steel waste greater efficiency is also low, while the longer profile, the need for two blanking turning steel, increasing the labor intensity of workers, so abandoned Re-election. After the decision to adopt a new punching process, namely broken material, punch tenon at the same time. Punch symmetrical shape set, a punch action, can simultaneously punch out one end of the two columns in the tenon-shaped. After trial production, the effect is good. 1. Die design to take off materials, Chong Tenon at the same time a new process, one can punch out two tenon, doubling the efficiency, and the punch
