Abstract

The present invention provides a method for forming a scroll spring and a device for forming a scroll spring. The method for forming a scroll spring includes the following steps: Step S10: The workpiece to be processed is processed by a positioning device and a first curve forming device to process The inner hook of the spiral spring, wherein the positioning device includes a first base and a positioning head, the positioning head is arranged on the first base, and the positioning head includes two positioning plates arranged oppositely, and a space between the two positioning plates is provided. The space forms a through groove for passing the workpiece to be processed, and one end of each positioning plate along the extending direction of the through groove forms a first forming part; the first curve forming device includes a second base and a first forming head, the first forming part is formed. A forming head is arranged on the second base, the first forming head has a second forming part, and the second forming part has a forming groove matched with the workpiece to be processed. The technical solution of the present invention effectively solves the problem of difficulty in processing the scroll spring in the prior art.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for forming a scroll spring and a forming device for the scroll spring. Background technique [0002] A scroll spring is a spring with one end fixed and a torque acting on the other end. Under the action of torque, the spring material produces bending elastic deformation. The scroll spring includes an inner hook and an outer hook, and the outer hook includes a first arc segment and a second arc segment that are connected to each other and are tangent to each other. At present, there are two main methods of manufacturing scroll springs: manual forming and numerical control forming. [0003] The method of manual forming refers to relying on the fitter to manually wind out the spiral coil of the scroll spring with the assistance of a special fixture. The manual molding method has higher requirements on the skills of the operator, poor controllability and man...
