Abstract

A method for coiling the truncated conic vortex spring includes such steps as cutting to obtain a long sheet strip, inserting its one end in an opening on a cylindrical mandrel, attaching an asbestor sheet to it, arranging a stop rod parallel with said mandrel and with a certain distance between them, driving the mandrel to rotate and forcing the sheet strip to be close to said stop rod, heating the sheet between them while winding, heat treating, cooling, and wetting and removing the asbestos sheet.

Description

technical field

[0001] The invention relates to a production method of a spring, in particular to a production method of a truncated cone scroll spring. Background technique

[0002] In the prior art, there is a truncated cone scroll spring, which can bear a relatively large load and absorb relatively large deformation energy. Good shock absorption. The rolling process of this kind of spring is relatively complicated. It is necessary to manufacture a pair of tower-shaped mandrels on a large lathe, fix the pre-cut long strips on the tower-shaped mandrels, and then burn them in a large heating furnace. The product can be obtained by through rolling and heat treatment after forming; the disadvantage is that the rolling process of this kind of spring is relatively complicated, and the gap between the layers of the spring is difficult to handle, which often causes the problem of inaccurate spacing.
