Spring manufacturer to introduce you to the cold and hot forming process

Spring each of the cold forming and hot forming process of is what? Spring production process there is a process, each process, must pay attention to the key point, or it is likely to cause the spring manufacturing is not successful. In the spring of the manufacturing process, there are two processes, cold forming and hot forming the two manufacturing process is very important, today spring manufacturer we guys detailed introduce of spring cold forming and hot forming and cold forming and hot forming process is what! A spring cold forming process, have the ability to a cold forming process automation technology and cold forming machine has developed into 12 feet in ( 0. 3 ~ 14) Within the scope of the mm stainless steel wire, the majority of forming in the eight claw forming machine. At this stage, the development prospect of forming machinery and equipment are: ( 1) Improve the forming rate, the key development prospect is forming rate of machinery and equipment, improve productivity. ( 2) Improve the precision of machinery and equipment parts, conditioning treatment to strengthen the actual effect, promote the overall characteristics of machinery and equipment, improve the use of machinery and equipment performance; ( 3) Increasing the length and the laser range finder, numerical control machine tool machine automatic feedback control of the manufacturing process. Second, the category of cold forming process. The present stage, larger
specifications big wire specifications spring up to 20 mm, compression spring machine = 2000 kpa, transmission ratio of 5. Choose reducing or raw materials such as diameter of small and medium-sized piece of spring and the axial force of spring cold forming technology still has limitations. A spring hot forming process, rate of hot forming process. At present, in our country, 9 ~ 25) Mm specifications forming machine chooses CNC2 shaft only in the spring compression spring machine, large
rate per minute 17 pieces, with a comparison with the capitalist countries, the difference is very big. Second, the big spring hot forming process management ability. Because only CNC2 axial spring compression spring machine, like three to pose less manipulation, accuracy is poor; And there is no automatic rotation of round controlling and adjusting organization, so hot coil spring forming technical strength and ability are low. Therefore, spring precision level and surface air oxidation carburizing level is low.
