Analysis of screw drawing: from process to application, this article understands the meaning and function of screw drawing

1. Process flow of screw drawing
Screw drawing is a metal processing process, mainly using wire drawing equipment and molds to stretch and plastic deformation of screws, thereby improving the strength and durability of screws. The main process of screw drawing includes the following steps:
1. Selection of raw materials
The raw materials of screw drawing are mainly metal materials, such as carbon steel, stainless steel, brass, aluminum alloy and so on. The choice of raw materials has a great impact on the subsequent processing technology and product quality.
2. Select mold and drawing equipment
The mold is one of the key factors to determine the shape of the screw, which is usually determined by the quality of the die steel, hardness, surface quality, processing accuracy and other factors. The choice of wire drawing equipment is also very important, and the corresponding equipment and process parameters are provided according to different materials and shapes.
3. Tensile and plastic deformation
The main process of screw drawing is to continuously stretch and plastic deformation the screw material through the wire drawing equipment to obtain better mechanical properties.
4. Shot peening
Shot peening treatment is mainly to improve the quality and corrosion resistance of the screw surface, improve the appearance quality and product performance.
Second, the role of screw drawing
Screw drawing is to improve the strength and durability of the screw, so that it can withstand greater load and tension, and better maintain tightness. Specifically, the role of screw drawing is mainly manifested in the following aspects:
1. Improve the strength and hardness of the material
By stretching and deforming, screw drawing increases the strength and hardness of the material, making it better able to withstand load and tension.
2. Improve the corrosion resistance of the material
Shot peening can improve the quality and corrosion resistance of the screw surface, improve the appearance quality and product performance.
3. Improve the appearance quality of products
Screw drawing can improve the appearance quality of the product, improve the beauty and decoration of the product.
4. Increase service life
By improving strength and durability, screw drawing can increase the service life of the product and reduce the cost of use.
In short, screw drawing is a very important processing technology, which plays a significant role in improving the mechanical properties, durability and appearance quality of products.
