What are the classifications of spring explained to you by Suzhou Spring Factory?

Xiaobian today to explain to you what are the classifications of spring? Let's distinguish from the following three aspects:

First, if we distinguish according to the nature of the force, the spring can be divided into tensile spring, compressive spring, torsion spring and tortuous spring.

Second, if according to the shape to distinguish, the spring can be divided into disc spring, ring spring, plate spring, spiral spring, truncated cone scroll spring and torsion bar spring and so on.

Third, if according to the process of production to distinguish, then the spring can be divided into cold coil spring and hot coil spring. As we often see the general cylinder spring because its production is relatively simple, but also can be produced according to the load situation into a variety of, simple structure of the spring, so until now this spring is widely used. Generally speaking, the production information of the spring is a high elastic limit, fatigue limit and impact toughness and better heat treatment performance, etc., generally commonly used materials are carbon spring steel, alloy spring steel and stainless spring steel and copper alloy, rubber and so on.

Mainly divided into the following two points:

First, one-time automation of cold forming process. The cold forming machine has now been developed to 12 claws. The steel wire in the range of (0.3 to 14) mm is basically formed at one time in the 8-claw forming machine. The development direction of forming process equipment: ① Improve the forming speed, the primary development trend is to improve the forming speed of equipment, that is, the production power; ② Improve the precision of equipment parts and strengthen the heat treatment effect to improve the durability of equipment; ③ Add the length sensor and laser rangefinder to automatically control the production process of the CNC forming machine.

Second, cold forming process range. Now the large wire diameter spring coiling machine, the specification can reach 20mm, =2000MPa, and the winding ratio is 5. The cold forming process of Minic-Block spring and eccentric spring with variable diameter or equal diameter material is still limited.
