Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0027] see Figure 1-Figure 3 As shown, the invention provides a kind of spring forming process, comprises the steps:

[0028] 1) Feeding: pull out the steel strip from the discharge roller and send it into the production line;

[0029] 2) Compression: Make the steel strip pass through the compression mechanism 1, apply pressure to the steel strip through the compression mechanism 1, and make the steel strip generate friction;

[0030] 3) Forming of the basic...

Abstract

The invention discloses a spring stretching forming process, which comprises the following steps: feeding; compacting; forming by stretching a steel strip; forming by reducing the size; cutting. Through the stretch forming process, the dimension of the formed steel strip spring is stable, and the force value error of the manufactured spring is small, thereby improving the application range of the spring. In particular, constant force springs, variable force springs and special elastic springs can be produced by changing the size of the spring forming, so that the springs manufactured by the stretch forming process have a wider range of applications.

Description

technical field [0001] The invention relates to the field of steel strip spring production, in particular to a spring forming process. Background technique [0002] Steel strip springs have high strength, hardness and yield ratio, and are mostly used in automobiles, railway vehicles, smart home appliances, medical equipment, military and aerospace fields. [0003] The applicant found that there are at least the following technical problems in the prior art: the existing steel strip spring forming process uses an extrusion forming process, and the forming size of the extrusion process cannot meet the technical requirements, and the force value error of the produced spring is about ±20 % or more, this results in poor applicability of the steel strip spring and a relatively small range of use. Its main technical disadvantages are poor spring performance stability, easy attenuation of the elastic force value, and easy deformation of the spring size during the use of the spring, ...
