Spring is a simple structure, stable characteristics of the commodity, in people's daily life is very common, this kind of spring in the production process is there some basic provisions, spring work no friction, not easy to cause flutter, spring volume is small, is a small and medium-sized lightweight commodity, the following Wuxi spring manufacturers to everyone in detail under the provisions of the production of torsion bar springs.
1. Provisions on both sides:
It is proposed to use the random die forging method or the upsetting method with bar top forging method to obtain continuous and uniform streamlined chemical fibers. The crystals of this type of streamlined chemical fiber move along the center line of the torsion bar and prevent the flow of the metal crystal chemical fiber connecting the shaft to the spline shaft tooth from being broken.
2. Regulations on the production and processing of the surface layer:
The surface of the spring must be fed with sufficient feed to ensure the final amount of removal, and in the case of cutting, it must ensure its machining accuracy, and there must be no knife lines or scratches. If the surface layer is not produced and processed, the surface carburizing level, surface defects, and the standard tolerance of the surface should be clearly defined.
3. Quenching and tempering treatment regulations:
Quenching and tempering treatment is an important part of improving the compressive strength of the spring, and the in-situ stress of the spring can be maximized.
4. Surface maintenance solution:
In order to avoid damage to the mechanical equipment on the surface of the etching, metal surface treatment (such as phosphating treatment, lacquer solution) and rubber strips, nylon, epoxy resin paint layer and other ways can be used for maintenance.
5. Provisions on raw materials:
The raw materials should meet the various regulations of the technical requirements of the relevant stainless steel plates. Raw materials generally should not have shrinkage porosity, small white spots, thermal fine cracks and other shortcomings that endanger the versatility of raw materials. Because the sulfur content and phosphorus content are very harmful to the characteristics of the raw materials of torsion bar springs, their composition should be controlled within 0.04%, and the cutting performance is better.
