Embodiment Construction

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 and Figure 6 As shown, a method for producing a thin-walled metal ring, placing the plate or strip in a progressive stamping die, includes the following steps in sequence: drawing step 29, drawing the plate or strip into an open top A cylinder with a closed bottom; punching step 30, punching a round hole at the bottom of the cylinder; flanging step 31, turning the circular edge of the bottom of the cylinder outward; shaping step 32, placing the cylinder on The progressive stamping die is in an annular closed cavity formed when the mold is closed, and then applies pressure to the annular area of ​​the connection between the top of the cylinder and the plate or strip material; blanking step 33, the cylinder is moved from the cylinder along the outer peripheral surface of the cylinder Separation on sheet or strip. The ring-shaped closed cavity is formed by the following steps: First, the shaping punch 1...

Abstract

The invention discloses a method for producing a thin-wall metal circular ring, which comprises the steps of deep-drawing, punching, turning up, shaping and blanking plate materials or strip-shaped materials on a grading stamping mould. The grading stamping mould used for implementing the method mainly comprises an upper mould part and a lower mould part, wherein a deep-drawing male mould, a punching male mould, a turning-up male mould, a shaping male mould and a blanking male mould are arranged on the upper mould part sequentially; the male moulds all pass through a discharging plate; an annular convex part is arranged on the part, which surrounds the shaping male part, of the discharging plate; a deep-drawing female mould, a punching female mould, a turning-up female mould, a shaping female mould and a blanking female mould are arranged on the lower mould part sequentially; and spring-ejecting parts are arranged in the cavities of the deep-drawing female mould, the turning-up female mould and the shaping female mould. The method solves the technical problems of low processing precision and low production efficiency of the metal circular ring with two straight end faces. The method has a simple structure and is widely applied to the production manufacturing industry of the metal circular ring in electronic industry.

Description

technical field [0001] The invention relates to a method for producing a thin-walled metal ring and a stamping die used therefor, in particular to a method for producing a thin-walled metal ring by using plate or strip material and a progressive stamping die used therefor. Background technique [0002] Progressive stamping die refers to a stamping die in which the press completes multiple stamping processes simultaneously at several different positions of the die in one stroke. The traditional mold structure is an eight-plate structure or nine-plate structure. The eight plates are the upper and lower die bases, the punch fixing plate, the punch backing plate, the die fixing plate, the die backing plate, the unloading plate, and the unloading plate. Backing plate; the structure of nine plates is added with a material guide plate. The blanking, flanging, bending, deep drawing, three-dimensional forming and other processes of parts can be completed in a pair of progressive sta...
