A method for forming a ring-shaped wool button and the ring-shaped wool button
By bending the metal wire into a wavy shape and laying it into an annular blank, combined with the stepwise graded extrusion technology of the stamping die, the problems of poor meshing and poor axial elasticity in the existing annular button molding technology are solved, and the good meshing and uniform elasticity of the annular button are achieved.

AI Technical Summary
Technical Problem
The existing annular wool button molding technology has problems such as poor meshing, easy delamination and poor axial elasticity, and it is impossible to achieve good end-face elastic contact and good performance annular wool buttons.
Method used
By bending the metal wire into a wavy shape, then laying it to form an annular blank, and performing multiple step-wise and graded extrusion through a stamping die, an annular hair button with good elasticity and engagement is formed.
Benefits of technology
It achieves good engagement of the annular wool buttons, uniform appearance size and good elastic properties, avoiding the problems of layering and poor axial elasticity.

Abstract
The present invention relates to a forming method of an annular wool button and the annular wool button, the forming method comprising the following steps: bending a straight metal wire to form a three-dimensional wavy metal wire; selecting a mandrel of a certain size, and setting two pin groups distributed along the axial interval on the outer periphery of the mandrel; winding and fixing the initial end of the three-dimensional wavy metal wire at the root of the first pin of the first pin group, then pulling the three-dimensional wavy metal wire along the axis of the mandrel and hanging it at the root of the first pin of the second pin group, then pulling the three-dimensional wavy metal wire and hanging it at the root of the second pin of the first pin group, repeating the above operation until the three-dimensional wavy metal wire is hung at the root of the last pin of the second pin group, completing the laying of a layer of three-dimensional wavy metal wire; repeating the above operation to obtain an annular wool button blank; and punching to obtain the annular wool button. The present invention can produce an annular wool button with good elasticity, non-stratified meshing, and uniformity.
