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).
管材的锯削：选用细齿锯条，当管壁锯透后随即将管子沿着推锯方向转动一个适当角度，再继续锯割，fastener价格，依次转动，直至将管子锯断。锯割时管子必须夹正。
Cutting of pipe: select a fine toothed saw blade， when the tube wall is sawed through a proper angle along the direction of the push saw， then continue sawing and turn， until the pipe is sawed. When sawing is cut， the pipe must be clamped.
手锯加工方法
扁钢的锯削：在扁钢锯口处划一周圈线，fastener分类，分别从宽面的两端锯下，两锯缝将要结接时，轻轻敲击使之断裂分离。这样锯削效率高，白山fastener，而且能较好地防止锯齿崩缺。反之若从窄面下锯，非但不经济，而且只有很少的锯齿与工件接触，工件越薄，锯齿越容易被工件的棱边钩住而折断。
Processing method of hand saw
Sawing of flat steel: a circular line at the cutting edge of flat steel， which is cut down from the two sides of the wide surface. When the two saws will be tied， it will be gently tapped and broken apart. The sawing efficiency is high， and the sawtooth collapse is prevented. On the ， if it is sawed under the narrow face， it is not economical， and only a few teeth are touched with the workpiece. The thinner the workpiece is， the more easily the sawtooth is caught and broken by the edges and edges of the workpiece.
