Embodiment 1

[0065] like figure 1 , 2 , 8, 9, and 10, the invention provides a spinning forming method of a W-shaped metal sealing ring, comprising the steps of:

[0066] S100. According to the axial section of the W-shaped metal sealing ring, calculate the height of the annular blank 1 of the W-shaped metal sealing ring, and prepare the annular blank 1 with a height;

[0067] S200. Spinning along the radial center of the annular blank 1 prepared in step S100 to process an annular waist groove 11, the waist groove 11 is sunken toward the direction where the axis of the annular blank 1 is located;

[0068] S300. performing spinning processing on the parts located on both sides of the waist groove part 11 in the annular blank 1 to form a W-shaped metal sealing ring;

[0069] Wherein, before spinning the parts located on both sides of the waist groove part 11 in the annular blank 1, the waist groove part 11 is embedded in the cavity of the second mold core 2, and the inside of the waist gro...

Embodiment 2

[0107] like figure 1 , 2 As shown, the present invention also claims to protect a spinning device for a W-shaped metal sealing ring, including a waist groove spinning device 9 and two end face spinning devices for processing the waist groove part 11 in the ring blank 1 10;

[0108] Two-end surface spinning device 10 includes

[0109] The second rotating shaft 81, the second rotating shaft 81 includes a conical conical portion;

[0110] The second mold core 2, the second mold core 2 is made up of at least two split type mold cores, each split type mold core is respectively connected with the conical part of the second rotating shaft 81; The cavity that matches the shape of the groove portion 11, the first side surface that matches the shape of the first bent portion 111 of the W-shaped metal sealing ring, and the second bent portion 112 of the W-shaped metal sealing ring a second side of matching shape;

[0111] The second rotary wheel 72, the second rotary wheel 72 is alw...

Abstract

The invention discloses a spinning forming method of a W-shaped metal sealing ring, which includes the following steps: S100. According to the axial section of the W-shaped metal sealing ring, the height of the annular blank of the W-shaped metal sealing ring is calculated, Prepare an annular blank with the height; S200. Spin along the radial center of the annular blank prepared in step S1 to form an annular waist groove, the waist groove faces the axis of the annular blank The direction where the heart is located is depressed; S300. Perform spinning processing on the parts located on both sides of the waist groove in the ring blank to form a W-shaped metal sealing ring. The invention can obtain a W-shaped metal sealing ring that is smooth, complete, and evenly spun; the invention inserts a support ring into the waist groove of the ring blank to increase the strength of the edge of the second mold core, effectively solving the problem of the ring blank. Difficult to locate technical issues.

Description

technical field [0001] The invention relates to the field of metal ring manufacturing, specifically provides a spinning forming method for a W-shaped metal sealing ring, and further relates to a spinning device for a W-shaped metal sealing ring. Background technique [0002] W-shaped metal sealing ring is a kind of axial self-tightening static sealing structure with new sealing form and better sealing effect. It has good resilience performance, strong vibration absorption ability, large deformation range, and good high vibration followability. , high vibration absorption capacity, long life and good wear resistance, especially suitable for working in harsh environments such as high temperature, high pressure, vibration and strong corrosive media in aviation and aerospace. [0003] The forming and manufacturing of W-shaped metal sealing rings usually adopts a multi-pass rolling process. The rolling forming process is a chip-free, continuous and progressive forming process. A...
