Abstract

The invention discloses a small compression spring static pressure method and a device thereof. A small compression spring and a standard part flat washer are placed on a spring screw in sequence, andthe small compression spring is pressed by a spring static pressure device, and the small compression spring is inserted into a pin hole in the spring screw by a wedge-shaped lock pin, and the smallcompression spring is fixed in a solid state. The spring static pressure device is used for assisting the quick installation and disassembly through the small compression spring static pressure methodto complete the static pressure. According to the small compression spring static pressure method, a wedge-shaped structure with a self-locking function is adopted, the static pressure operation of the small compression spring can be quickly completed, and the static pressure operation efficiency of the small compression spring is greatly improved.

Description

technical field [0001] The invention relates to a spring static strong pressure method and its device, in particular to a small compressed spring static strong pressure method and its device. Background technique [0002] If the residual stress in the spring material is opposite to the direction of the working stress, the load-bearing capacity of the spring can be improved. The strong pressure treatment of the compression spring is to press the spring until the surface stress of the material exceeds the yield point, so that negative residual stress is generated on the surface, and positive residual stress is generated at the core, which improves the bearing capacity of the compression spring. Static strong pressure is a process method of strong pressure treatment. The spring is pressed to the required height (usually pressed to the parallel circle, referred to as "pressed parallel"), and released after parking for 6-48 hours. The static strong pressure performance is stable ...
