Problems solved by technology

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 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

Embodiment Construction

[0014] The rolling method of truncated cone scroll spring can be carried out in the following steps:

[0015] A) Insert one end of the pre-cut long strip sheet into the opening 3 provided by the shaft end of a cylindrical mandrel 2, and make an acute angle between the length direction of the sheet material 5 and the axis of the mandrel 2, and A stop bar 4 is fixed at a position where the mandrel 2 is parallel and at a certain distance, and the distance between the axis of the mandrel 2 and the stop bar 4 is not less than the radius of the scroll spring after the coil is formed;

[0016] B) Rotate the mandrel 2 to make the sheet material 5 lean against the stop rod 4, heat the sheet material between the mandrel and the stop rod, and continuously wind the mandrel 2, and stick the asbestos cardboard 1 against the stop rod 4 during winding. It is wound on the mandrel together on the sheet metal; the purpose of heating is to make the metal sheet soft and easy to bend.

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. Contents of the invention [0003] The object of the present invention is to p...
