五金冲压件加工包括冲裁、弯曲、拉深、成形、精整等工序。冲压件加工的材料主要是热轧或冷轧（以冷轧为主）的金属板带材料，例如碳钢板、合金钢板、弹簧钢板、镀锌板、镀锡板、不锈钢板、铜及铜合金板、铝及铝合金板等。
stamping process includes blanking， bending， drawing， forming， finishing and other processes. The main materials for stamping parts are hot rolling or cold rolling (cold rolling)， such as carbon steel， alloy steel plate， spring steel plate， galvanized plate，紧固件报价， tin plate， stainless steel plate， copper and copper alloy plate，紧固件， aluminum and aluminum alloy plate.
在冲压件行业里，冲压有时也称板材成形，但略有区别。所谓板材成型是指用板材、薄壁管、薄型材等作为原材料进行塑性加工的成形方法统称为板材成形，此时，厚板方向的变形一般不着重考虑。

清除冲压机床滑块底面、工作台面（或垫板平面）以及模具的上、下模座平面内的任何杂物或**。手工扳动冲压机床飞轮（或操纵点动按钮），调整上滑块到上死点位置，并转动调节螺杆，将连杆长度调到短（即闭合高度大）。
Remove any material or foreign object on the bottom of the stamping machine slide， working table (or pad plane)，紧固件生产厂家， and the upper and lower die base of the mold. Manually pull the stamping machine flywheel (or point moving button)， adjust the upper slider to the upper dead point， and rotate the adjusting screw， the length of the connecting rod to the shortest (i. e. the maximum height of the closed height).
