specific Embodiment approach

[0028] As a specific embodiment of the present invention, the inner bottom surface of the first groove 32 is provided with a second groove 33, and a push plate 331 is arranged in the second groove 33; the push plate 331 is connected to the second groove by a second spring 332 33 inner bottom surface; through the cooperation between No. 2 spring 332 and push plate 331, prevent the parts after stamping from being embedded in No. 1 groove 32; There will be sliding friction between the No. 1 groove 32, and the parts will also have active friction with the outer wall of the fixed mold 4. If the active friction between the parts and the No. 1 groove 32 is greater than the friction between the parts and the fixed mold 4, the parts will When demolding, the parts will be clamped in the No. 1 groove 32, and when the movable mold 3 is lifted by the cylinder 11, the stamped parts will rise together with the movable mold 3, and then the stamped parts will be removed manually, at this time ...

Abstract

The invention belongs to the technical field of moulds, in particular to a stamping mould and a stamping forming method thereof. The mould comprises an upper bracket and a lower bracket; the upper bracket is provided with a movable mould; the upper end surface of the movable mould is connected to the upper bracket through an air cylinder, the left and right side walls of the movable mould are provided with first rods, the first rods penetrate through first through holes formed in the upper bracket, the lower end surface of the movable mould is provided with a first groove, and a fixed mould isarranged below the first groove; the fixed mould is fixedly connected to the lower bracket, and an outer ring of the fixed mould is provided with a bearing platform; the bearing platform is used forplacing a steel plate, the upper end surface of the bearing platform is flush with that of the fixed mould, a circular groove is formed in the middle of the bearing platform, the diameter of the circular groove is greater than that of the fixed mould, and the lower end surface of the bearing platform is connected to the lower bracket through a first spring; and the lower bracket and the upper bracket are connected together through bolts. Through the cooperation of the fixed mould, the bearing platform and the first spring, demoulding of a stamped part is realized.

Description

technical field [0001] The invention belongs to the technical field of molds, in particular to a stamping mold and a stamping forming method thereof. Background technique [0002] Stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, called cold stamping die (commonly known as cold stamping die). Stamping is a pressure processing method that uses a mold installed on a press to apply pressure to the material at room temperature to cause separation or plastic deformation to obtain the required parts. [0003] In the stamping die in the application number 2018111321447, the workpiece placed on the lower die is punched and formed by the upper die, and then the clamping block is pressed so that the clamping block retracts into the clamping slot, and then the frame is pulled down, When the upper end of the frame is lower than the plate, the stamped workpiece is removed from the...
