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).

五金冲压件材料的硬度检测，其主要目的就是确定购入的金属板材退火程度是否适于随后将要进行的冲压件加工，不同种类的冲压件加工工艺，需要不同硬度级别的板材。

stamping material hardness testing, the main is to determine whether the purchase of metal sheet annealing is suitable for subsequent stamping parts processing, different types of stamping processing technology, the need for different hardness levels of the plate.

槽钢的锯削：槽钢的锯削与扁钢一样，但是要分二次从宽边面往下锯，不能在一个面上往下锯，应尽量做到在长的锯缝口上起锯，因此工件必须多次改变夹持的位置。

Channel steel sawing: the channel sawing of the channel steel is the same as that of the flat steel, but it must be sawed down two times from the wide side, and can not be sawed down on one surface, and should be sawed on the long saw mouth as far as  so the  of the clamping must be changed many times.

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 avoid the crack of the saw teeth.
