Embodiment Construction

[0020] 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 progressive stamping die for producing thin-wall metal rings, which comprises an upper die portion and a lower die portion. A deep drawing convex die, a punching convex die, a turnup convex die, a reforming convex die and a blanking convex die are installed on the upper die portion in sequence. All the convex dies penetrate through a discharging board, and an annular protrusion portion is arranged on the discharging board at the portion around the reforming convex die. Correspondingly, a deep drawing concave die, a punching concave die, a turnup concave die, a reforming concave die and a blanking concave die are installed on the lower die portion in sequence, and an elastic ejector is respectively arranged in cavities of the deep drawing concave die, the turnup concave die and the reforming concave die. The progressive stamping die for producing thin-wall metal rings solves the technical problems of low processing precision of metal rings with two straight end faces and low production efficiency and is reasonable in structure and widely used in metal ring manufacture industries in electronic industries.

Description

technical field [0001] The invention relates to a stamping die for producing thin-walled metal rings, in particular to a progressive stamping die for producing thin-walled metal rings by using plates or strips. 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 stamping dies. [0003] At present, ring products used for conduc...
