Abstract

The invention discloses a net rack rod part machining method. The net rack rod part machining method comprises the following steps that shot blasting is conducted on the outer wall of a steel pipe through a steel pipe shot blasting device, a shot blasting dead zone is avoided by clamping the inner wall of the steel pipe, the steel pipe is rotated to enable the outer wall of the steel pipe to be subjected to 360-degree shot blasting treatment, steel balls beat the outer wall of the steel pipe through multiple times of refraction, the beating frequency of the steel balls sprayed out at a time isincreased, collision among the steel balls is reduced, steel pipe surface treatment is accelerated, a sprayer head is inserted into the steel pipe to conduct shot blasting on the inner wall of the steel pipe, and meanwhile the steel balls achieve refraction and collision on the inner wall of the steel pipe. According to the net rack rod part machining method, the structure is simple and easy to operate, the inner wall and the outer wall of the steel pipe can be quickly subjected to shot blasting treatment, the spraying one-time utilization rate of the steel balls is increased, the rejection rate of the steel balls is decreased, and the net rack rod part machining method can be applied to production.

Description

technical field

[0001] The present invention relates to a method for processing grid rods, in particular to a steel pipe shot peening. Background technique

[0002] In the past, steel pipes used in structures such as buildings or bridges were subjected to shot peening in order to remove rust or scale on the surface of steel pipes. Layer and its sundries, so that it can obtain a fine bright surface, improve the tensile and compressive strength of the workpiece, increase the adhesion for the paint protection of the inner surface, achieve the purpose of anti-corrosion, pipe protection, and prolong the service life of the steel pipe. The steel ball thrown out only hits the surface of the steel pipe once, and is bounced off by the steel pipe. The steel ball utilization rate is low and the shot blasting speed is slow. At the same time, the steel balls collide with each other, and the steel ball scrap rate is high. Contents of the invention

[0003] In order to overcome the defi...
