Embodiment 1

[0016] The specific preparation steps of the high wear-resistant wave spring mentioned in the present invention are as follows:

[0017] a) Material selection and preparation. The raw material of the wave spring is an alloy spring steel plate with a thickness of 0.3-0.35mm. The main components and percentage ratios of the alloy spring steel plate are: C 0.55%, Mn 9%, Cr 4.5 %, Ni 0.7%, Si 0.5%, Cu 0.35%, Al 0.12%, Mo 0.22%, Ti 0.025%, Pd 0.11%, Ce 0.01%, and the rest is Fe; the impurity P content is controlled below 0.03%, and the impurity The content of S is controlled below 0.03%;

[0018] b) Pretreatment, the pretreatment process is spheroidizing annealing treatment, the treatment process is as follows: first, the steel plate is slowly heated to 750°C-760°C in the furnace; then, it is kept at this temperature for 4.5 hours; then, the steel plate is Cool to about 550°C; finally, take out the steel plate and air cool to room temperature;

[0019] c) Stamping processing, usi...

Description

technical field [0001] The invention relates to a preparation method of a wave spring, in particular to a preparation method of a high wear-resistant wave spring, belonging to the technical field of springs for bearings. Background technique [0002] Wave spring is a kind of spring widely used in motor, textile machinery, hydraulic equipment, automobile and other industries, also known as wave spring. The wave spring is a thin ring-shaped elastic metal element composed of several crests and troughs. It is usually used in occasions where the load and deformation are not large, and the spring stiffness is small and axial preload is required. Its manufacturing method is usually to first stamp the metal sheet into a ring-shaped blank, then use a mold to stamp the wave shape along the ring direction, and finally undergo heat treatment to make it have resilience. [0003] The current wave spring has a simple structure, a high degree of automation in the preparation process, excel...
