沖壓件是靠壓力機和模具對板材、帶材、管材和型材等施加外力，使之產(chǎn)生塑性變形或分離，從而獲得所需形狀和尺寸的工件（沖壓件）的成形加工方法。沖壓和鍛造同屬塑性加工（或稱壓力加工），合稱鍛壓。

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).

在沖壓件行業(yè)里，沖壓有時也稱板材成形,但略有區(qū)別。所謂板材成型是指用板材、薄壁管、薄型材等作為原材料進行塑性加工的成形方法統(tǒng)稱為板材成形，此時，厚板方向的變形一般不著重考慮。

In the stamping industry, stamping is sometimes referred to as sheet metal forming, but there is a slight

 The so-called sheet forming means the forming method of plastic forming with sheet, thin-walled tube and thin material as raw material, which is called sheet forming. At this time, the deformation of the thick plate is generally not cidered.

管材的鋸削：選用細齒鋸條，當(dāng)管壁鋸?fù)负箅S即將管子沿著推鋸方向轉(zhuǎn)動一個適當(dāng)角度，再繼續(xù)鋸割，依次轉(zhuǎn)動，直至將管子鋸斷。鋸割時管子必須夾正。

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.
