Glass shot blasting device for optimizing surface of small-wire-diameter spring

Abstract

The invention provides a glass shot blasting device for optimizing the surface of a small-wire-diameter spring. The glass shot blasting device comprises a shot blasting chamber. The two sides on the top of the shot blasting chamber are communicated with an air conveying pipeline and an air outlet pipeline respectively. The bottom of the shot blasting chamber is communicated with a conveying pipeline used for conveying glass shots. A rotary base is arranged at the bottom of the shot blasting chamber and provided with a net roller where the spring is placed. One end of the conveying pipeline is communicated with the bottom of the shot blasting chamber, and the other end of the conveying pipeline is communicated with the top end of the net roller. According to the glass shot blasting device, the surface color and gloss of the spring can be further improved, and the surface of the spring can be provided with meticulous textures and the uniform and attractive metal gloss. The glass shot blasting device is particularly suitable for small-wire-diameter springs, the product rejection rate can be greatly reduced, manpower and material resources and the product production cost are reduced, and the product performance is optimized.

Description

technical field [0001] The invention relates to the technical field of spring surface optimization, in particular to a shot blasting device for optimizing the surface of springs with small wire diameters. Background technique [0002] Shot blasting is a cold treatment process used to remove processing burrs on the surface and edges of springs and improve surface strength, improve the fatigue strength of parts and the ability to resist stress and corrosion, increase smoothness, reduce surface wear, and improve wear resistance of parts, including Cleans and strengthens surfaces. Cleaning the surface, as the name implies, is to remove impurities such as surface scale and improve the appearance quality of the product; strengthening the surface is to use high-speed moving projectiles to continuously impact the surface of the workpiece, thereby improving the fatigue resistance and service life of the parts. [0003] In the field of spring products, some high-performance spring...

Problems solved by technology

[0003]In the field of spring products, some high-performance springs can use steel ball shot blasting process to optimize the surface of the spring, but some springs are due to the small wire diameter or steel wire Softer, if steel ball shot blasting is used, it will not strengthen the surface of the spring but will destroy the performance of the spring
