Description

This application relates to the technical field of fine wire drawing, and more particularly to a method for dynamically adjusting the drawing force during high-speed drawing of fine wires, a device for dynamically adjusting the drawing force during high-speed drawing of fine wires, electronic equipment, and a storage medium. With advancements in science and technology and expanding industrial demand, fine metal wires are widely used in fields such as aerospace, precision instrument manufacturing, and electronic communications due to their superior performance. High-speed drawing is a demanding process in the production of fine wires. Strict control of the drawing force is necessary during the drawing process to ensure the mechanical performance, surface quality, and processing accuracy of the wire. While high-speed drawing can increase production efficiency, it also comes with problems such as fluctuations in tensile force, wire breakage, and die wear. Therefore, real-time measurement and adjustment of the drawing force during the drawing process is particularly important to ensure production stability and the quality of the finished product. Conventional fine wire drawing machines mostly use fixed tensile force settings and manual adjustment methods, making it difficult to respond to real-time changes in tensile force during high-speed drawing. This leads to unstable wire tension during the drawing process, making wire breakage or uneven tensile force more likely, and making it difficult to achieve continuous high-speed production. To more clearly explain the technical concept of the embodiments of this application, the drawings used in the embodiments are briefly described below. The drawings described are merely examples of some embodiments of the present invention and do not limit the scope.

Current fine wire drawing equipment mostly uses fixed tensile force settings and manual adjustment methods, making it difficult to respond to real-time changes in tensile force during high-speed drawing. These technologies have the following drawbacks: 1. Insufficient monitoring of tensile force: Conventional equipment generally lacks accurate dynamic monitoring of tensile force, making it impossible to obtain real-time data on changes in drawing force during high-speed drawing. This results in unstable wire tension during the drawing process, making wire breakage or uneven tensile force more likely. 2. Delayed adjustment response: Conventional syst
