壓住材料?？朔鹘y(tǒng)的模具設(shè)計結(jié)構(gòu)，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(wěn)，而材料又可被壓緊。關(guān)鍵成形部位，卸料板一定做成鑲塊式結(jié)構(gòu)，以方便解決長時間沖壓所導(dǎo)致卸料板壓料部位產(chǎn)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.

日常模具生產(chǎn)中，應(yīng)注意維護沖切凸、凹模刃口的鋒利度。當沖切刃口磨損時，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.

薄板：鋸削時盡可能從寬面鋸下去，若必須從窄面鋸下時，可用兩塊木墊夾持，連木塊一起鋸下，也可把薄板直接夾在虎鉗上，用手鋸作橫向斜推鋸，使鋸齒與薄板料接觸的齒數(shù)增加，避免鋸齒崩裂。

Thin plate: sawing as far as  as wide as when sawing. If must be sawed from narrow surface, it can be held by two wooden blocks and sawed together with wooden blocks. The sheet can be clipped directly to the vise, and a hand saw is used as a transverse oblique saw to increase the number of teeth contacted with the sheet material and avoid the crack of the saw teeth.
