Shaped spring forming machine usually refers to the production of all kinds of stretch springs, torsion springs and various kinds of clips and other elastic components of the special forming equipment. This kind of special purpose machine tool is more complicated than the coil spring spring machine, also known as multi-station machine tool. The common special machine for winding tail hook and torsion spring in China is straight tail winding spring machine. Its action adopts rack and pinion mechanism, feeding mode is reciprocating one-way feeding mechanism, coiling spring form is cored, its pitch control depends on the vertical direction of the movement of the sliding rod through the CAM to achieve. The cutting mechanism is also controlled by a CAM, and such machines can only make simple torsion springs.

The machine used to make the clip ring is called a bending machine, which takes the form of a multi-station machine. The steel wire is fed into the mold and then bent into the desired shape through a series of clamping actions. The key of this kind of machine tool lies in the design and manufacture of the mould. The adjustment takes longer.

Due to the variety and shape of the spring, the spring mechanism is required to meet the requirements of easy adjustment and suitable for many varieties. The new special-shaped spring forming machine has been able to complete a series of complex actions from wire feeding to spring winding and bending, and the end can also complete the hook and ring processing at the end of the spring. It can not only roll the compression spring, but also the tension spring, torsion spring, double - head torsion spring, double - layer spring, all kinds of springs can be made freely.
