Special-shaped spring forming machine generally refers to the production and manufacture of a variety of tension springs, torsion springs and a variety of clasp ring and other elastic components of the special forming machine equipment. This kind of special equipment is more complex than the production of torsion spring coil customs, also known as multi-station CNC lathe. The common private aircraft winding tail hook torsion spring in China is the straight tail press spring machine. Its posture uses rack organization, the feeding method is reciprocating unilateral gift organization, the spring is cored winding, its pitch diameter manipulation with the help of the vertical orientation moving slide according to the camshaft to complete. The disconnecting tissue is also controlled by the camshaft. This kind of equipment only makes simple torsion spring. The domestic model specification is Z56-25. Only torsion springs with wire diameter below 2.5 mm are produced.

The equipment used for the production of clasp is called the bending machine, which is a multi-station mode. The steel wire is fed into the mold according to the feed, and then the steel wire is bent into the desired shape according to a series of fixture positions. The key point of this kind of CNC lathe is the design scheme and production of the die. The die and CNC blade must be replaced when the type is replaced. It takes a long time to adjust.
