Embodiment 1

[0023] Embodiment one: if figure 2 As shown, we insert the spherical sleeve 2 at the beginning end and the end end of each bundle of linear spring steel wire 1, and the spherical sleeve 2 is provided with a cylindrical body, which is hollow in the axial direction, and the hollow size is the same as the cross-sectional size of the linear spring steel wire 1. Similarly, the end of the linear spring steel wire 1 is inserted into the cylindrical body of the spherical sleeve 2 with an interference fit, the spherical sleeve 2 is put on at the end of each bundle of linear spring steel wire, and the spherical sleeve 2 is removed when making the spring , and recycled.

Embodiment 2

[0024] Embodiment two: see image 3 , in order to provide the linear spring steel wire 1 that draws bundles to have a fixed point of bundling, the starting end of spring steel wire 1 is bent into crotch 5 with the end end, puts spherical cover 2 again.

Embodiment 3

[0025] Embodiment three: as Figure 4 As shown, the end of the linear spring steel wire 1 is directly bent into an earring 11, and the earring 11 is oval, and the end of the linear spring steel wire 1 is bent back to be close to the linear spring steel wire 1 of its own straight line. , also can first put soft plastic cover on the end of the linear spring 1 that is not bent, and then bend and shape, so as to achieve safety effect equally.

Abstract

The invention relates to the technic for bundling the raw material of springs, in particular to a method for processing the end heads of bundled linear spring steel wires. The method is characterizedin that the starting ends and the tailing ends of each bundle of linear spring steel wires are manufactured into circular end heads by protector application and the arching technology and then are labeled. The end head has the advantages of reasonable structural design and easy processing, is provided with an arched structure, and is convenient for bundling and solves the problem that the untreated end heads injure operating staff or equipment when the raw material of linear steel is pulled.

Description

technical field [0001] The invention relates to spring raw material binding technology, in particular to a method for treating the ends of linear spring steel wires after they are bundled. Background technique [0002] When drawing linear spring raw materials, because the ends at the beginning and the end are not handled or handled improperly, after bundling, it is difficult for the operator to get the ends when the ends are in the next process, which is time-consuming and laborious. There are burrs and even sharp hooks at the end of the machine, which are very easy to injure the operator. If when drawing raw material, all adopt end structure of the present invention at the beginning and the end of every bundle of material, then can avoid such accident completely. [0003] There are many ways to deal with the end, and they are generally designed for their own products. [0004] For example, the patent No. 200720090071.0 is a refrigerator evaporator steel wire end structure...
