Dongguan City, Xu-feng Hardware Products Factory is a professional manufacturer of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Disc spring is a spring washer spring Precision sheet metal or forging blanks made of a truncated cone section, can withstand axial load spring dish. Can be divided into non-bearing surface and there are two types of bearing surfaces, can be used individually, but also on the combined portfolio, or a combination of composite laminated combination group uses a disc spring, under static load or variable load. Process spring dish: cutting - lathe - Deburring - stress relief - forming - heat treatment - extreme pressure - Shot - Surface treatment - test - dynamometer - packaging and storage . Most of the raw materials in accordance with strict strip thickness tolerances to produce strip with different thicknesses were used car parts, stamping, precision stamping, plasma arc / flame cutting, etc. processing. According to different applications, dish-shaped spring according to strict thickness tolerances using isothermal martensitic hardening or austempering heat treatment. Shot peening technology to improve the fatigue life of the spring plays a significant role. Preservative treatment process so that the spring dish improves corrosion levels. Dongguan City, Xu-feng Hardware Products Factory is a professional manufacturer of metal springs, lathe parts and stamping parts of the enterprise, the factory has advanced technology and equipment, modern workshops and professional personnel, products sold around the world. Sheet metal disc spring is wound with a rectangular cross section truncated cone spiral spring, a conical coil spring with a circular cross-section which characteristic line is similar. The main feature is the small size, load, variable stiffness; widely used in small spaces, load bearing and shock absorber big occasions. Truncated cone spiral spring by spring parameters and carrying case classification scroll springs, etc. can be divided helix angle disc springs, and other pitches, such as stress three forms, namely: ① such as helix angle truncated cone spiral spring, ② etc. Pitch truncated cone spiral spring, ③ and other stress truncated cone spiral spring. The spring design and manufacture complex than those commonly used materials 60Si2MnA, 50CrVA springs, surface treatment methods are blue, painting and so on. Please specify when ordering free height, maximum deformation, maximum diameter, minimum diameter, maximum load, thickness, plate width, the working circle, total laps. We can according to your conditions, the selection of suitable materials, and satisfy your needs.
