冲头是成型模具中经硬化、精密加工的凸模部件,作为凹模的凸形对应件。它对金属板材或其他材料施加受控力,以执行冲裁、冲孔、成型或拉深等操作。冲头通常在压力机内垂直运动,与固定的凹模配合,通过机械变形或剪切作用形成所需形状或孔洞。 冲头的工作原理是施加集中的机械力使材料变形或剪切。当安装在压力机中时,冲头下降进入凹模腔,迫使工件材料流动、断裂或贴合模具形状。冲头与凹模边缘之间的间隙决定了操作是剪切(切割)还是成型(不切割的成形)。

A blanking punch cuts the entire perimeter of a part from sheet metal, producing the desired component. A piercing punch creates holes within a part without cutting the outer perimeter. The clearance and edge preparation differ between these applications.
Punches should be visually inspected every shift for wear or damage. Dimensional checks should be performed weekly or every 10,000 cycles. Regular maintenance includes cleaning, lubrication, and edge condition verification to prevent premature failure.
Common causes include excessive clearance between punch and die, misalignment, material hardness variations, inadequate lubrication, fatigue from cyclic loading, and improper punch material selection for the application.
