增设强压功能。即对卸料镶块压料部加厚尺寸(正常的卸料镶块厚H 0.03mm)，以增加对凹模侧材料的压力，从而***冲切时冲压件产生翻料、扭曲变形。

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.

压住材料。克服传统的模具设计结构，在卸料板上开出容料间隙(即模具闭合时，卸料板与凹模贴合，而容纳材料处卸料板与凹模的间隙为材料厚t-0.03～0.05mm)。如此，冲压中卸料板运动平稳，而材料又可被压紧。关键成形部位，卸料板一定做成镶块式结构，以方便解决长时间冲压所导致卸料板压料部位产生的磨(压)损，鱼尾板厂家，而无法压紧材料。

Press the material. In order to overcome the traditional mold design structure，鱼尾板生产商， the clearance of material is opened on the discharge plate (i.e.，鱼尾板价格， 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 ***oothly， 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.

简单来说钣金件是金属薄板壳体，冲压件就是用拉伸机或冲床等加工的工件1，钣金件在折弯过程中厚度不会有变化，但在汽

车钣金壳体中应为敲击等原因，一部分表面会有一定变化。冲压厂是不能确定落料尺寸的，鱼尾板，应该是在定做模具时由模具厂试定出来的。

In a simple way， the sheet metal part is a metal sheet shell， and the stamping part is 1 of the workpiece， which is processed by a drawing machine or a punch press. The thickness of the sheet metal parts will not change during the bending process， but in the steam.

The surface of the automobile shell should be knocked and so on. Part of the surface will change. The stamping plant is unable to determine the blanking size. It should be determined by the mold factory when making the mould.
