Radial flow type. Gaining large cycle flow with baffle's cooperation. Coupled Thermal-mechanical Analysis of Plastic Shear Zone and Die Damage in Thick Plate Fine Blanking Process 径流型,配合挡板可得上下循环流,循环量大,剪切作用好。厚板精冲塑性剪切带热力耦合分析与模具失效
According to the feature of the deformation zone in ring gear gag precision blanking, the effect of hydrostatics stress on metal plastic is analyzed in the theory. 根据齿圈压板精密冲裁变形区受三向压应力作用的特点,理论上分析了静水压应力对金属材料塑性的影响;
The results show that the shear zone of workpiece can be heated by electrical current to an appropriate blanking temperature in a short time interval, which enables a sufficient reduction of the shear strength of the work material as well as the blanking force. 结果表明,电加热可在较短时间内在工件的冲切区形成合适的冲切温度,显著降低材料的破坏强度,从而可有效降低冲切力。
