Shot peening system for inner wall of steel cylinder

Abstract

The invention relates to a shot peening system for an inner wall of a steel cylinder, which comprises a compressed air source, a sand-blasting tank, a recovery bucket elevator, a recovery bucket, a driving device, a dedusting hood, the steel cylinder, a sand-blasting gun, a sand-blasting processing device, a deduster, a fan and a chimney, wherein the compressed air source is used for feeding blasting shots in the connected sand-blasting tank into the sand-blasting gun of the sand-blasting processing device through a sand-blasting valve of the sand-blasting tank; the sand-blasting gun is coaxially placed in the steel cylinder; the steel cylinder is connected with the recovery bucket; the recovery bucket is connected with the recovery bucket elevator; the recovery bucket elevator is connected with the sand-blasting tank; the sand-blasting gun is driven by the sand-blasting processing device to displace axially; and gas in the steel cylinder is collected by the dedusting hood so as to be fed into the deduster and is discharged by the fan through the chimney. According to the shot peening system, compressed air is adopted as driving force, and sand blasting is accelerated to generate a certain kinetic energy which is sprayed to the inner wall of the steel cylinder, so that scales (iron rust) on the inner wall of the steel cylinder, turning residues and attachments generated by stretching in the inner wall of the steel cylinder are cleaned; a bright and clean metal surface is obtained through processing; and the smooth finish reaches sa2.0-2.5(GB8923-88).

Description

technical field [0001] The invention belongs to the field of surface treatment, and relates to cleaning the inner wall of an accumulator shell (steel cylinder), in particular to a system for shot blasting and derusting the inner wall of a steel cylinder. Background technique [0002] During the manufacturing process of the inner wall of the steel cylinder, especially the accumulator shell, due to the production process, there are factors that are not conducive to the use of the product, such as scale (rust), attachments, and residual stress generated during the preparation process. In order to eliminate the above-mentioned unfavorable factors, the sandblasting machine for cleaning the inner wall of steel cylinders is commonly used in the industry at present. Since the shape of the steel cylinder is usually that one end has a larger hole and the other end has a small hole or no hole, at present, the way to clean and derust the inner wall of this type of steel cylinder is to i...
