Computer spring machines can produce a variety of springs. In the process of making springs by computer spring machines, bending tools are required. It is bent into the desired spring pattern by a bending tool, and then cut to complete the operation.

At present, the bending tool is made of a metal bar, and a groove for accommodating the wire is opened at one end of the tool. During the bending, the wire is bent at the groove of the bending tool.

When the wire needs to be bent to Z In the font, the bending speed of the bending tool in the prior art is slow, the processing efficiency is low, and the quality of the product is not high.

Curling is an accessory device for improving the processing efficiency of a spring machine. The curling device includes a curling head, a bending blade, a turntable, and a driving device.

The driving device can drive the curling head to rotate in the middle of the turntable. The curling head is provided with a rotating groove for accommodating a wire.

The turning discs are respectively arranged around the curling head, and the turning disc drives the bending blade head to rotate around the curling head under the driving of the driving device.
