Problems solved by technology

In the existing technology, the external polishing is to use a combination of different coarse-grained hemp wheels, grinding wheels, cloth wheels and wool wheels to obtain a corresponding smooth surface; internal polishing is to use various specifications of grinding heads to reciprocate or rotate inside the pipe. Movement, cutting the inner surface of the pipe, which has the advantages of good flatness and high brightness. The disadvantage is that most of the internal and external polishing cannot be operated at the same time. The operation is complicated and there are many processes, and it cannot adapt to different inner and outer diameters. Polishing of stainless steel pipes, and the brightness of the finished product after polishing does not last long
The advantage of chemical polishing is that its surface flatness and smoothness cannot meet the requirements, and the cost of electrochemical polishing is too high, which is not conducive to the realization of

Abstract

The invention discloses a polishing unit of stainless steel pipes. The polishing unit used for polishing outer and inner walls of a stainless steel pipe comprises a frame and a support rail; the support rail disposed on one side of the frame is used for supporting the stainless steel pipe to be polished; two sides of the middle of the support rail are provided with notches; two sides of each notch are symmetrically provided with pre-polishing mechanisms used for primarily polishing the outer wall of the stainless steel pipe to be polished. The polishing unit is characterized in that the other side of the frame is provided with a first drive mechanism and a secondary polishing mechanism; the secondary polishing mechanism connected with the first drive mechanism is used for polishing the inner and outer walls of the stainless steel pipe at the same time; at least one module and isolating oil are further provided; the modules are used for adjusting the inner diameter of a sleeve according to different outer diameters of stainless steel pipes; the isolating oil is injected into a connecting pipe through an oil filler.

Description

technical field [0001] The invention relates to a processing plant for use in the case of stainless steel pipe manufacture. More specifically, the present invention relates to a polishing device and method of use of a stainless steel pipe used in a stainless steel pipe manufacturing situation. Background technique [0002] Existing stainless steel pipes will form a layer of black or gray scale on the surface during the manufacturing process or after being placed for a certain period of time. The main components are Cr203, NiO, and very difficult to tolerate FeO, Cr203. Quality; on the other hand, it also affects the performance of the product, so appropriate measures should be taken to remove it. Usually after welding or heat treatment, the surface of the stainless steel pipe needs to be polished to make it have better flatness, corrosion resistance and smoothness. Specifically, the usual polishing methods for stainless steel pipes mainly include mechanical polishing, chem...
