Automatic polishing and grinding equipment for inner hole of metal pipe

Abstract

The invention relates to automatic polishing and grinding equipment for an inner hole of a metal pipe. According to the automatic polishing and grinding equipment for the inner hole of the metal pipe,the problems that when the inner wall of the metal pipe is polished and ground, the production efficiency is low, the workshop environment is polluted, and explosion is likely to occur are solved. The automatic polishing and grinding equipment is characterized in that a pressing wheel device (8) and a supporting wheel device (9) are arranged on the upper portion and the lower portion, at a thirdmaterial blocking device (6), of an inclined sliding table (2) correspondingly; polishing devices (11) are arranged on the two sides of a dustproof shell (7) correspondingly, and the dustproof shell (7) communicates with a draught fan through an air suction pipeline (12). The automatic polishing and grinding equipment can be controlled through a PLC, the automation degree is high, and the production efficiency is effectively improved; and a relatively-closed polishing space is formed in the dustproof shell, so that dust generated during polishing does not diffuse in a workshop, pollution to the workshop environment is avoided, dust explosion accidents are avoided, and the anti-explosion requirement is met.

Description

technical field [0001] The invention relates to polishing and grinding equipment, in particular to an automatic polishing and grinding equipment for inner holes of metal pipes. Background technique [0002] Metal pipes are often used to transport fluid media, and are widely used in petroleum, chemical, pharmaceutical and other industries. When the metal pipe is used to convey the medium, the inner wall of the metal pipe is required to be smooth and free of burrs. Therefore, the inner wall of the metal pipe needs to be polished and polished during processing. It is easier to polish and polish the inner wall of the shorter metal tube, and the metal tube for conveying the medium is often longer, and the length of the metal tube is 3 meters or longer. At present, there is no automatic polishing and grinding equipment for the inner wall of the metal tube. At that time, only simple machines and tools can be used for manual operation, which is time-consuming and labor-intensive fo...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems of low production efficiency, polluting the workshop environment and prone to explosion when polishing the inner wall of the metal tube, the invention provides an automatic polishing and grinding equipment for the inner hole of the metal tube. The automatic polishing and grinding equipment for the inner hole of the metal tube can be controlled by PLC, and the degree of automation Higher, which effectively improves the production efficiency. A relatively closed polishing space is formed in the dustproof shell, so that the dust generated by polishing will not be dispersed in the workshop, the workshop environment will not be polluted, and dust explosion accidents will not occur, which meets the explosion-proof requirements.
