Pipe polishing machine and polishing method thereof

Abstract

The invention discloses a pipe polishing machine and a polishing method thereof, and belongs to the field of surface polishing. The polishing machine comprises a base mechanism, a feeding mechanism, a polishing mechanism and a discharging mechanism, wherein the base mechanism comprises a machine frame and a machining table top arranged above the machine frame; the feeding mechanism comprises a disc feeding device arranged on the machining platform top, a pipe sliding platform and two linear propelling mechanisms arranged at the starting end and the tail end of the pipe sliding platform; the polishing mechanism comprises an outer surface polishing device and an inner surface polishing device; the outer surface polishing device and the inner surface polishing device are respectively aligned with the two propelling mechanisms. According to the polishing machine, a conveying belt, the disc feeding device and the pipe sliding platform are matched to replace manual feeding and discharging, the working intensity of workers is reduced, and the automation efficiency is improved; and a polishing head of the inner surface polishing device is made of sand cloth and is designed in a cross shape, so that the polishing acting force is more uniform, and the quality of polished products is improved.

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
