Pipe polishing machine and polishing method thereof

Abstract

The invention discloses a polishing machine for pipes and a polishing method thereof, belonging to the field of surface polishing. It consists of four parts: basic mechanism, feeding mechanism, polishing mechanism and discharging mechanism. Wherein, the basic mechanism includes a frame and a processing table arranged above the frame; the feeding mechanism includes a disc feeding device arranged on the processing table, a pipe sliding platform, and a starting end and an end of the pipe sliding platform. There are two linear propulsion mechanisms at the end; the polishing mechanism consists of two parts, the outer surface polishing device and the inner surface polishing device, which are respectively aligned with the two propulsion mechanisms. The invention cooperates with the conveyor belt, the disc feeding device and the pipe sliding platform to replace the manual loading and unloading, reduce the work intensity of the workers, and improve the automation efficiency; the polishing head of the inner surface polishing device is made of sand leather, and its shape The cross-shaped design can make the polishing force more uniform and improve the quality of the polished product.

Description

technical field [0001] The invention belongs to the field of surface polishing, in particular to a pipe polishing machine and a polishing method thereof. Background technique [0002] With the improvement of product quality and product upgrading, the requirements for polishing also increase. In the production and processing of stainless steel pipes, polishing treatment is required, especially in the fields of chemical industry and medicine. strict requirements. On the one hand, most of the existing polishing methods use ordinary manual polishing or semi-automatic polishing, requiring the user to directly participate or adjust the position of the polished pipe on the side. Moreover, most of the existing semi-automatic polishing equipment only polishes the inner or outer surface of the pipe, and manual loading and unloading is required to polish the inner and outer surfaces of the pipe at the same time, which undoubtedly increases the labor intensity of the workers.

AI Technical Summary

Problems solved by technology

On the one hand, most of the existing polishing methods use ordinary manual polishing or semi-automatic polishing, which requires the user to directly participate or adjust the position of the polished pipe on the side

Moreover, the existing semi-automatic polishing equipment is more likely to polish the inner or outer surface of the pipe only, and manual loading and unloading is required to polish the inner and outer surfaces of the pipe at the same time, which undoubtedly increases the labor intensity of the workers.

[0003] On the other hand, in the inner surface polishing equipment used in the existing polishing equipment, when processing thin and long pipes, due to the excessive length of the throwing rod, it is easy to shake a lot, and the rigid throwing head is easy to collide with the inner surface of the pipe. Rigid collision, so not only can not reduce the friction evenly, it may even be due to excessive concentration of stress, but instead increase the roughness of the inner wall of the pipe and reduce the product quality
