Problems solved by technology

In China, although the application of abrasive belt grinding technology has a long history, its development is slow, and there has been no automatic abrasive belt grinder suitable for pipe wall thickness grinding.
In addition, many foreign manufacturers implement the processes of thickness measurement and grinding on different machine tools during the grinding of the wall thickness of the tube blank, which makes the process scattered, the cost of the machine tool is high, and the disadvantages of occupying a large area

Abstract

The invention discloses an excircle abrasive belt grinding method of the wall thickness of a tube, which comprises a lathe bed and a linear guide rail, wherein the linear guide rail is installed on the lathe bed and provided with a grinding head mechanism; a feed mechanism and a blanking mechanism are respectively arranged on both ends of the lathe bed; an auxiliary supporting roller mechanism and a positioning clamping mechanism are arranged below the grinding head mechanism and installed on the lathe bed; and a wall thickness measuring mechanism is installed on the grinding head mechanism. According to the excircle abrasive belt grinding method, the excircle wall thickness of the tube can be detected and ground on the same lathe, the excircle abrasive belt grinding method has the advantages of simple structure, convenience in operation, high grinding precision and efficiency and good stability and reliability, and the uniformity of the wall thickness of the tube is guaranteed.

Description

technical field [0001] The invention relates to a method for grinding the outer circular abrasive belt of pipe wall thickness, which is used for detecting and grinding the outer circular wall thickness of pipe materials. Background technique [0002] The pipes are processed from zirconium ingots through hot extrusion, machining and other processes into finished tube blanks, and then the finished tube blanks are finally processed by multi-pass Pilger rolling, heat treatment, degreasing and pickling, machining, non-destructive testing and other processes. Just made it into a finished product. In order to ensure that after the important process of multi-pass Pilger rolling, the specified size requirements from the tube blank to the finished tube, the uneven wall thickness caused by hot extrusion must be measured, and the wall thickness must be controlled by machining and grinding. Within an appropriate range, if the wall thickness unevenness of the zirconium tube during the ro...
