Stamping part

Abstract

The invention discloses a stamping part, and belongs to the technical field of stamping devices. The stamping part comprises a die holder, an upper die assembly and a lower die. The die holder is driven to move up and down. The upper die assembly is fixed to the bottom of the die holder and moves along with the die holder. The lower die is arranged below the upper die assembly and cooperates withthe upper die assembly in the up-and-down direction. An oil cylinder material hitting device is arranged at the bottom of the die holder. Floating ejector rod assemblies which can float up and down are arranged in the upper die assembly. The oil cylinder material hitting device abuts against the upper ends of the floating ejector rod assemblies in a push mode, the lower ends of the floating ejector rod assemblies stretch into a die core groove formed in the bottom of the upper die assembly, and the floating ejector rod assemblies are driven by the oil cylinder material hitting device. According to the stamping part, the floating ejector rod assemblies are pushed by the oil cylinder material hitting device to move downwards, a workpiece is pushed out of the die core groove of the upper dieassembly, and therefore the workpiece can be separated from the upper die assembly as the return stroke of the upper die assembly is conducted, the workpiece falling height is small, the workpiece deformation cannot be caused, and the blanking quality and the yield are greatly improved.

Description

technical field [0001] The invention relates to the technical field of stamping devices, in particular to a stamping component. Background technique [0002] Punching is a stamping process that uses a die to separate part of the material or process part from another part of the material, process (process) part or waste. Blanking is a general term for the separation processes such as shearing, blanking, punching, punching, notching, sectioning, chiseling, edge trimming, tongue cutting, cutting, and trimming, and it accounts for the largest proportion in stamping production. In the blanking process, the sheet metal is sheared and deformed along a certain contour line by using the cutting edge of the die and separated. Except for the metal near the shear contour line, the sheet itself does not produce plastic deformation, so it is punched by a flat plate. The processed parts are still in a flat shape. [0003] Existing stamping equipment generally pushes the punched and forme...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem that the existing stamping equipment uses a punching rod to beat the material, the workpiece falls out of the mold cavity, and the falling height is large, and the workpiece is easily deformed when it hits the lower mold after falling. Assemblies and the lower mold, the bottom of the mold base is equipped with an oil cylinder feeding device, and the upper mold assembly is equipped with a floating ejector assembly that can float up and down. The floating ejector assembly is pushed down by the oil cylinder feeding device to move the workpiece from the upper mold. The core groove of the component is ejected, which can make the workpiece separate from the upper die assembly at the same time as the upper die assembly returns. The falling height of the workpiece is small and will not cause deformation of the workpiece, which greatly improves the punching quality and yield
