壓住材料。克服傳統的模具設計結構，在卸料板上開出容料間隙(即模具閉合時，卸料板與凹模貼合，而容納材料處卸料板與凹模的間隙為材料厚t-0.03～0.05mm)。如此，沖壓中卸料板運動平穩，而材料又可被壓緊。關鍵成形部位，卸料板一定做成鑲塊式結構，以方便解決長時間沖壓所導致卸料板壓料部位產生的磨(壓)損，而無法壓緊材料。

Press the material. In order to overcome the traditional mold design structure, the clearance of material is opened on the discharge plate (i.e., when the die is closed, the discharge plate and the die are fitted, and the gap between the discharge plate and the die is t-0.03 to 0.05mm). In this way, the discharging plate moves smoothly, and the material can be pressed tightly. In the key forming part, the discharge plate must be made into an inlaid structure to facilitate the solution of the grinding (pressure) loss caused by the pressing part of the unloading plate for a long time, and the material can not be pressed.

增設強壓功能。即對卸料鑲塊壓料部加厚尺寸(正常的卸料鑲塊厚H 0.03mm)，以增加對凹模側材料的壓力，從而抑制沖切時沖壓件產生翻料、扭曲變形。

Additional pressure function. In order to increase the pressure on the material of the die side, the pressure of the material in the die side is increased by the thickness of the material of the unloaded insert (normal unloaded insert thickness H 0.03mm), so as to suppress the turning and distortion of the stamping parts.

在沖壓件行業里，沖壓有時也稱板材成形,但略有區別。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.

清除沖壓機床滑塊底面、工作臺面（或墊板平面）以及模具的上、下模座平面內的任何雜物或異物。手工扳動沖壓機床飛輪（或操縱點動按鈕），調整上滑塊到上死點位置，并轉動調節螺桿，將連桿長度調到短（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).
