Special-shaped spring

Profiled spring forming machine usually refers to the special forming equipment for producing all kinds of stretch springs, torsion springs and various snap rings and other elastic components. The complexity of this kind of special machine is higher than the coiling machine of compression spring. Domestic winding end hook torsion spring machine is a common special straight end winding spring machine. Its action adopts rack and pinion mechanism, feeding mode is reciprocating one-way feeding mechanism, coiling spring form is cored winding, its pitch control depends on the vertical direction of the sliding bar through the CAM to achieve. The cutting mechanism is also controlled by CAM. This kind of machine can only produce simple torsion spring. The domestic model is z56-25. We can only produce torsion springs with wire diameter below 2.5mm.

The machine used to make the clasp is called a press bender, which takes the form of multi-station. The steel wire is fed into the mold, and then through a series of clamping actions, the steel wire is bent into the desired shape. The key of this kind of machine tool lies in the design and manufacture of mould. It takes a long time to adjust.

Due to the variety and shape of spring, the spring mechanical can meet the requirements of convenient adjustment and suitable for many kinds. The new special-shaped spring forming machine has been able to complete a series of complicated actions, such as feeding from steel wire to coil spring and bending, and finally finishing the processing of hook and ring at the end of spring. It can not only coil compression spring, but also stretch spring, torsion spring, double-head torsion spring, double-layer spring, all kinds of card spring can be used to produce freely. There are many types of foreign special-shaped spring forming machines, the main types include ZO type and FTU type from WAFIOS company in west Germany, MS type and AT type from TC and HP company in France, MCF type from okano corporation in Japan, and vf-800 type from emerging corporation in Japan.
