Problems solved by technology

After the surface of the spring is coated, if it is compressed, it will often destroy the coating and affect the performance of the spring
In the prior art, after the surface treatment of the commonly used springs, if compression aging (i.e. heating and loading aging) is carried out, the general method is to wear the spring on a mandrel and squeeze it together for aging. This process not only causes large The coating on the inner diameter of some spring parts is damaged, and the amount of scrap is large, which shortens the service life, affects the work efficiency, and is not conducive to the stability of the spring.

Abstract

The invention discloses a spring compression aging cladding layer protection jig and a using method thereof. The protection jig comprises jig bodies (3) and an aging mandril (4). The spring compression aging cladding layer protection jig is characterized in that the aging mandril (4) can be movably provided with a plurality of jig bodies (3); the middle parts of the jig bodies (3) are provided with bulged positioning shoulders (2); the jig bodies (3) are axially provided with through holes (5); a blocking seat (1) is arranged at one side of the aging mandril (4), and is provided with one of the jig bodies (3); the jig bodies (3) are symmetrical with respect to the meso-position planes of the positioning shoulders (2). The using method is simple, feasible, efficient, practical, and reliable to operate.

Description

technical field [0001] The invention belongs to the technical field of protection fixtures, and in particular relates to a spring compression aging coating protection fixture and a using method thereof. Background technique [0002] In order to improve the anti-corrosion performance of the spring, the commonly used method is coating treatment. After the surface of the spring is coated, if it is compressed, the coating will be destroyed in many cases and affect the performance of the spring. In the prior art, after the surface treatment of the commonly used springs, if compression aging (i.e. heating and loading aging) is carried out, the general method is to wear the spring on a mandrel and squeeze them together for aging. This process not only causes large The coating on the inner diameter of some spring parts is damaged, and the amount of scrap is large, which shortens the service life, affects the work efficiency, and is not conducive to the stability of the spring.
