Problems solved by technology
However, the rigidity of the compressor cylinder is strong, and the lowest natural frequency is greater than the maximum excitation frequency of the vibration aging device. It is necessary to use a device to reduce the frequency of the compressor cylinder, and select a suitable excitation point and vibration frequency to compress In the existing vibration aging process, there is no vibration aging device and method that can be applied to the above-mentioned compressor cylinder. Many enterprises and predecessors have solved the vibration aging of the compressor cylinder. Methods and means, a large number of experiments have been carried out, and a suitable process means and method have not been obtained so far

Abstract
The invention discloses a vibration stress relief method for a compressor cylinder and relates to the technical field of casting destressing. The compressor cylinder is provided with a circular inner hole. A vibration stress relief device for the compressor cylinder is used and comprises a vibration exciter, a vibration tester and a platform. The platform is 4000mm in length, 1200mm in width and 200mm in height. The top of the platform is provided with a plurality of parallel T-shaped grooves. At least one T-shaped bolt is disposed in at least one T-shaped groove. Each T-shaped bolt penetrates through an external pressure plate. The vibration exciter is fixed at one end of the corresponding T-shaped groove on the top of the platform, and the vibration tester is disposed at the other end of the corresponding T-shaped groove on the top of the platform. By the vibration stress relief method compared with the prior art, machining residual stress of the compressor cylinder can be eliminated effectively, and average residual stress decrease rate is 55%.
Description
technical field [0001] The invention relates to the technical field of stress relief treatment of castings, in particular to a method for vibration aging of a cylinder body of a compressor. Background technique [0002] The compressor cylinder is one of the important parts of the compressor. It is cast from alloy cast iron; there is a compressor cylinder with a cylindrical external shape and a complex internal structure; there are many processing procedures, long production cycles, and high manufacturing precision requirements. According to the process requirements, after the rough casting of the compressor cylinder, an aging treatment is carried out to eliminate the casting residual stress; after that, a series of mechanical processing is carried out, and before the compressor cylinder is ground, the second The purpose of secondary aging treatment is to eliminate the residual stress of the mechanical processing of the compressor cylinder to improve the stability of its pro...
