Inner surface polishing machine for stainless steel pipe production

Abstract

The inner surface polishing machine for stainless steel pipe production comprises a base, a mounting plate and a stainless steel pipe fixedly mounted at the top of the mounting plate, the top of the base is slidably connected with a mounting platform, and a mounting groove is formed in the top of the mounting platform; and an operation mechanism used for grinding and polishing the interior of the stainless steel pipe is arranged at the top of the mounting platform, the operation mechanism comprises a bearing seat, a mounting rod is rotationally connected to the inner wall of the bearing seat, the mounting rod and the stainless steel pipe are coaxially arranged, and a polishing head is fixedly connected to the outer wall, close to the supporting legs, of the mounting rod. Through cooperation of the structures, the inner walls of pipelines with different lengths can be polished and ground, scraps generated by polishing can be pushed and cleaned, and polishing and grinding can be matched with spraying of a polishing agent.

Description

technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to an inner surface polishing machine for producing stainless steel pipes. Background technique [0002] Since the 1990s, China has started to reduce wall thickness and cost, and has promoted the application of stainless steel pipes, such as direct drinking water pipes. Pipeline direct drinking water has developed rapidly in domestic cities such as Beijing, Shenzhen, Shanghai, and Chongqing, with developed economies. China's medium-sized cities are also actively planning to catch up. In direct drinking water, stainless steel piping is undoubtedly second to none. At present, most public places such as hotels in China have been equipped or are configuring direct drinking water pipes. [0003] When stainless steel pipes are used in direct drinking water pipes, there are high requirements for the smoothness of the inner surface, that is, the inner wall. Usually, the inner ...

AI Technical Summary

Problems solved by technology

[0003] When stainless steel pipes are used in direct drinking water pipes, there are high requirements on the smoothness of the inner surface, that is, the inner wall. Usually, the inner wall of the stainless steel pipe is polished and polished. The rapid rotation of the spindle during the polishing operation is likely to cause the polishing debris to be easily removed. The shutter wheel or the grinding head is driven twice, which will destroy the grinding and polishing effect, affect the smoothness, and the polishing effect is not good. There is also a grinding and polishing method that includes a polishing agent. Although it can prevent the dust from affecting the grinding to a certain extent, but this The method is easy to cause the polishing agent to stay on the inner wall, and it is easy to mix with the chips to affect the feeding of the polishing, and the efficiency is low
