上针盘的加工方法
By employing a two-stage heat treatment process, heat treatment deformation is controlled, improving the flatness and structural strength of the upper needle plate. This solves the radial unevenness problem caused by traditional heat treatment and ensures the production of high-quality fabric.

AI Technical Summary
Technical Problem
Traditional heat treatment processes result in unevenness in the radial direction of the upper needle plate, affecting flatness and reducing fabric quality.
Method used
A two-stage heat treatment method is adopted. The first stage is a high-temperature heat treatment at the tip of the upper needle plate, and the second stage is a low-temperature heat treatment at the middle of the reference surface. Combined with uniform single-point flame gun treatment, the amount of deformation during heat treatment is controlled.
Benefits of technology
It effectively reduces deformation after heat treatment, improves the flatness and structural strength of the upper needle plate, and ensures the production of high-quality fabric.
