Abstract

The invention belongs to the field of a spring and particularly relates to a fence type spring and a manufacturing method thereof. For the problems that a spring body with large diameter, low height and large compression ratio cannot be manufactured due to limitation of spring line diameter at present as well as the upper plane and the lower plane of a linear spring are stressed non-uniformly dueto single line, the invention provides the following scheme: the fence type spring comprises a spring body; the spring body comprises a plurality of connecting pieces; a plurality of connecting piecesare fixedly connected sequentially and annularly; a plurality of connecting pieces consist of a plurality of wavy gaskets; a butt-weld welding point is arranged between the adjacent two wavy gaskets;the adjacent two wavy gaskets are fixedly connected through the butt-weld welding point; the blank of the spring with large diameter, low height and large compression ratio is filled, the stability of the product is improved, the wavy gaskets and the connecting pieces can be positioned rapidly during welding, time is saved, and welding accuracy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a fence spring and a manufacturing method thereof. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force, and return to their original shape after removing the external force. They are also called "springs". They are generally made of spring steel. The types of springs are complex and diverse. Coil springs, leaf springs, special-shaped springs, etc. For the spring industry, for a long time, there has been a passive situation in which low-grade ordinary springs have oversupplied and high-end products (high-strength, high-stress, special-shaped parts, special materials) have been in short supply. The output of my country's spring industry has become saturated. According to expert statistics, my country's annual spring production has reached 4 billion pieces. There are 21 c...
