介绍一种高精度球面滑履零件冷成形模具,在实际应用中该模具能实现滑履成形,但模芯经常断裂,而且滑履挤压件的薄壁端口发生微塑变形。通过对模芯断裂和顶出变形分析,将模芯由台阶配合改作锥面配合,并将模具脱模机构改成梯度脱模,从而很好地解决了模芯断裂和挤压件顶出变形的问题。有效保护模具和保证挤压件尺寸精度,具有较高的应用价值。
A cold forming die for high precision spherical shoe parts is introduced. In practice, the die can be used to form the shoe, but the die often breaks, and the thin-walled port of the shoe extruding part undergoes plastic deformation. Through the analysis of mold core rupture and top extrusion deformation, the mold core is changed from a step fit to a cone fit, and the mold release mechanism is changed into a gradient demoulding so as to solve the problem that the core rupture and the extrusion top extrusion deformation The problem. Effectively protect the mold and ensure the dimensional accuracy of the extrusion, with high application value.
