Spring machine is a spring processing automation equipment, hot forming and cold forming are two main spring processing technology. In the face of these two processes, the situation of the spring machine is different. The following is a brief introduction to the spring processing of two forming process!

Spring cold forming process:

Cold forming process one-time automation ability, cold forming spring machine has developed to 12 claw, in the range of (0.3~14)mm steel wire, basically in 8 claw forming function a forming, the process range of maximum specifications can reach 20mm, 2000mpa, rotation ratio 5, However, the cold forming process of minIC-block spring and eccentric spring with variable diameter or equal diameter material still has limitations. At present, the development direction of forming process equipment is as follows:

1, improve the forming speed, the main development trend is to improve the equipment forming speed, that is, production efficiency;

2, improve the precision of equipment parts, enhance the effect of heat treatment, improve the durability of equipment;

3, increase the length sensor and laser rangefinder, automatic closed-loop control of nc molding machine manufacturing process;

Spring hot forming process:

1, hot forming process speed capacity, the current specifications of Our country (9~25)mm only CNC2 shaft hot spring coiling machine, the maximum speed is 17 pieces per minute. Compared with the spring machine in developed countries, the gap is very large.

2. Control ability of large spring thermal forming process. Because there is only CNC 2 axis hot rolling spring machine, the shape control is less than three directions, the precision is poor; There is no automatic rod rotation control and adjustment mechanism, so the forming technology level and ability of hot rolled spring are low. Therefore, the accuracy level and surface oxidation decarbonization level of the spring is also low. These are domestic spring machine in the process of hot forming some problems.

The above content is for the spring of cold and hot forming process, I hope to help you!
