Multi-stage grinding and polishing device for metal pipe machining and grinding and polishing process

Abstract

The invention discloses a multi-stage grinding and polishing device for metal pipe machining, and belongs to the technical field of metal machining. The multi-stage grinding and polishing device for metal pipe machining comprises a base, the inner wall of the base is rotationally connected with a threaded lead screw a, the peripheral side face of the threaded lead screw a is in threaded connectionwith a metal pipe fixing assembly, the upper surface of the base is fixedly connected with a pipe wall cleaning mechanism, the inner wall of the base is rotationally connected with a threaded lead screw b, a first-stage grinding mechanism is in threaded connection with the peripheral side face of the threaded lead screw b, the upper surface of the base is fixedly connected with a second-stage grinding mechanism, the metal pipe fixing assembly comprises a movable base, the inner wall of the movable base is in threaded connection with the threaded lead screw a, one surface of the movable base is fixedly connected with a support, and one surface of the support is fixedly connected with a fixed base. Through the design of the metal pipe fixing assembly, the pipe wall cleaning mechanism, the first-stage grinding mechanism and the second-stage grinding mechanism, the problem that an existing metal pipe grinding device is poor in practicability due to the fact that only one-time grinding isconducted on a metal pipe and the operation process is complex is solved.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to a multi-stage grinding and polishing device for metal pipe processing. Background technique [0002] Pure metals are generally solid at room temperature (except mercury), with metallic luster (that is, strong reflection of visible light), and most of them are excellent conductors of electricity and heat, with ductility, high density, and high melting point. Metal resources widely exist in the earth's crust and oceans. Except for a few very inactive metals such as gold and silver, which exist in the form of simple substances, the rest exist in the form of compounds. Metals exist widely in nature and are widely used in daily life. , is a very important and most widely used class of substances in modern industry. [0003] In the field of industrial manufacturing, a large number of metal pipes will be used. During the production and processing of metal pipes, th...

Problems solved by technology

[0003] In the field of industrial manufacturing, a large number of metal pipes will be used. During the production and processing of metal pipes, the metal pipes will be polished to make the metal pipes meet the use standards. When the existing metal pipe grinding devices are used, usually only The metal tube will be polished once, and the operation process is relatively cumbersome, resulting in poor grinding effect of the device and low convenience of use
