沖壓件是靠壓力機(jī)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).

日常模具生產(chǎn)中，應(yīng)注意維護(hù)沖切凸、凹模刃口的鋒利度。當(dāng)沖切刃口磨損時，材料所受拉應(yīng)力將增大，從而沖壓件產(chǎn)生翻料、扭曲的趨向加大。

In daily mold production, attention should be paid to sharpness of punching and concave die edges. When the cutting edge is worn, the tensile stress of the material will increase, and the stamping and bending will increase.

清除沖壓機(jī)床滑塊底面、工作臺面（或墊板平面）以及模具的上、下模座平面內(nèi)的任何雜物或異物。手工扳動沖壓機(jī)床飛輪（或操縱點動按鈕），調(diào)整上滑塊到上死點位置，并轉(zhuǎn)動調(diào)節(jié)螺桿，將連桿長度調(diào)到短（即閉合高度大）。

Remove any material or foreign object on the bottom of the stamping machine slide, working table (or pad plane), and the upper and lower die base of the mold. Manually pull the stamping machine flywheel (or point moving button), adjust the upper slider to the upper dead point, and rotate the adjusting screw, the length of the connecting rod to the shortest (i. e. the maximum height of the closed height).
