Spring correcting device

Abstract

The invention relates to a spring correcting device. The spring correcting device is used for processing a spring structure; the spring structure comprises a spring body, a lower locating plate and anupper locating plate, wherein the lower locating plate and the upper locating plate are arranged at the two ends of the spring body correspondingly; firstly, whether axial stress and circumferentialstress of the spring body are balanced or not is judged in manner of detecting; corresponding influence positions having errors can be acquired by judging the movement locus of a detection feedback needle; each influence position is heated, and hardness is reduced during temperature rise; deformation amount of each influence position of the spring body under drive of an axial regulating part is different from that of other positions; and a change in shape can be produced by a feature that metal is in a solid state when being cooled, so that the elastic force of the spring body tends to be perpendicular, and the acting force of the spring body tends to be perpendicular.

Description

technical field [0001] The present invention relates to spring correcting equipment, and more particularly, to a spring correcting device. Background technique [0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials are deformed under the action of external force, and return to their original shape after the external force is removed. Also known as "spring". Generally made of spring steel. The types of springs are complex and diverse. According to the shape, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. [0003] After the modern industry occurs, novel springs such as gas springs, rubber springs, scroll springs, die springs, stainless steel springs, air springs, memory alloy springs have also been there except disc springs. The spring detection needs attention: 1. The support ring can choose cold and hot methods according to the product requirements. It is not allowed to heat the spr...

Problems solved by technology

[0004] At present, there is a problem with springs with larger volumes. Due to their high production costs, their reliability depends on materials and has a greater impact on the structure of the springs. Generally speaking, there are two problems as follows: 1. The same spring The elastic force of each coil in the coil is not equal, which is called axial error at this time. This error will cause the metal elastic fatigue to occur more easily in the unit position, and affect the life of the spring.
