增设强压功能。即对卸料镶块压料部加厚尺寸(正常的卸料镶块厚H 0.03mm)，以增加对凹模侧材料的压力，从而***冲切时冲压件产生翻料、扭曲变形。凸模刃口端部修出斜面或弧形。这是减缓冲裁力的有效方法。减缓冲裁力，即可减轻对凹模侧材料的拉伸力，从而达到***冲压件产生翻料、扭曲的效果。

日常模具生产中，应注意维护冲切凸、凹模刃口的锋利度。当冲切刃口磨损时，材料所受拉应力将增大，从而冲压件产生翻料、扭曲的趋向加大。

冲压件是靠压力机和模具对板材、带材、管材和型材等施加外力，使之产生塑性变形或分离，从而获得所需形状和尺寸的工件（冲压件）的成形加工方法。冲压和锻造同属塑性加工（或称压力加工），合称锻压。

Stamping is a forming and processing method for workpiece (stamping parts) by applying external force to plate, strip, pipe and profile by press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure machining).

薄板：锯削时尽可能从宽面锯下去，若必须从窄面锯下时，可用两块木垫夹持，连木块一起锯下，也可把薄板直接夹在虎钳上，用手锯作横向斜推锯，使锯齿与薄板料接触的齿数增加，避免锯齿崩裂。

Thin plate: sawing as far as as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and ***oid the crack of the saw teeth.
