仪表冲压件生产模具设计结构与制造质量,直接影响冲压件的质量。冲裁模的间隙大小,不但影响压件的质量,也影响到模具的使用寿命。如采用合理的冲裁间隙就会大大减少繁重的毛刺劳动,提高生产效率。为此,我们对冲裁时的合理间隙进行了优选:试验过程:试验条件在冲头阴模刃口较锋的情况下用厚度等于2.5mm的20号钢进行 Stamping parts production mold design and manufacturing quality structure, a direct impact on the quality of stamping parts. Blanking Die gap size, not only affect the quality of pressure parts, but also affect the service life of the mold. Such as the use of reasonable blanking gap will greatly reduce the burr labor, improve production efficiency. To this end, we have a reasonable gap blanking the preferred: Test process: test conditions in the case of punch die edge front with a thickness equal to 2.5 mm 20 steel
