先冲压未印制网格的铝板，进行模具调整，调整到铝板冲压不开裂之后，再冲压

Stamping first unprinted aluminum mesh, for adjusting the mold, it is adjusted to not crack after punching an aluminum plate, an aluminum plate and then stamped grid printed. Since the mesh roughness of the printed portion becomes high, so the first stamping press oil coated on the surface of the plate, in order to improve the lubricity of the grid portion to reduce the adverse effects on the stamped grid. And ensure that the original stamping parts oiled crack is enough. Drawing member finally obtained uncracked measurement and analysis. <br>After stamping, marking 2 measurement area, area identification as shown in FIG.

First stamp the aluminum plate of the unprinted mesh, make mold adjustment, adjust to the aluminum plate stamped open crack, and then stamp the aluminum plate printed on the mesh. Because the roughness of the grid printing part becomes higher, stamping oil is applied to the surface of the sheet before stamping to improve the lubrication of the mesh site and reduce the adverse effect of the mesh on stamping. And to ensure that the original stamping cracking site of the oil is sufficient. Finally, the uncracked extension is obtained for measurement and analysis.<br>After the stamping is formed, the 2 areas are marked for measurement, and the area identification is shown in Figure 3.

First punch the aluminum plate without grid, adjust the die, and then punch the aluminum plate with grid after the aluminum plate does not crack. Due to the higher roughness of the grid printing part, the stamping oil is applied on the plate surface before stamping to improve the lubrication of the grid part and reduce the adverse impact of the grid on the stamping. Moreover, it is necessary to ensure that the original stamping cracking parts are coated with oil. Finally, the uncracked drawing parts are measured and analyzed.<br>After stamping, Mark 2 areas for measurement, and the area identification is shown in Figure 3.<br>
