增設(shè)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(cè)材料的壓力，從而抑制沖切時沖壓件產(chǎn)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.

檢查、核對模具和沖壓機床。在安裝模具前，要確認(rèn)沖壓機床為沖壓工藝的型號，并檢查模具的尺寸、工作要求是否與沖壓機床的技術(shù)參數(shù)（裝模高度、滑塊行程等）相匹配，沖壓機床的狀態(tài)足否良好。

Check and check die and stamping machine. Before installing the mould, it is necessary to confirm that the stamping machine is the designated type of the stamping process, and check the size of the die and the work requirements to match the technical parameters of the designated stamping machine (the height of the die, the slider stroke, etc.), and the state of the stamping machine is good or not.

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(nèi)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(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).
