Steel pipe outer wall polishing device

Abstract

The invention discloses a steel pipe outer wall polishing device, and belongs to the field of mechanical equipment. According to the key points of the technical scheme of the steel pipe outer wall polishing device, a to-be-machined steel pipe is clamped and fixed by steel pipe clamping plates and driven by a motor to rotate during polishing; the to-be-machined steel pipe is located in the centersof three polishing rollers distributed in a triangular shape; the to-be-machined steel pipe can generate rapid friction with the roller faces of the polishing rollers during rotation, so that the steel pipe is polished through the relative rolling between the polishing rollers and the to-be-machined steel pipe; due to the fact that the complete surface of the steel pipe can be polished by rotatingthe steel pipe for a plurality of circles, the polishing efficiency of the steel pipe outer wall polishing device is higher than that of an existing mode that polishing is completed by horizontally moving a polishing pad on the surface of the rotating steel pipe; time consumed for polishing the steel pipe with a certain length is shorter; and during polishing, the motor only outputs power to therotating action of the steel pipe, so that the motor shaft load of a motor is simpler, the energy consumption of the motor during operation is lower, the motor does not need to be replaced frequently,and the use and maintenance cost is lower.

Description

technical field [0001] The invention belongs to the field of mechanical equipment, and in particular relates to a steel pipe outer wall polishing device. Background technique [0002] The existing stainless steel tube outer wall polishing device, such as a stainless steel tube outer wall polishing device disclosed in Patent No. CN109465688A, includes a shell, a bracket, a lifting cover, a filter plate, a rotating base, a steel pipe splint, a transmission shaft, a motor, The movable rod, polishing pad, turntable, connecting rod and gasket are arranged on the upper end of the shell, the lifting cover is installed on the bracket, the filter plate is installed in the shell, and the rotating base is symmetrically installed on the left and right side walls of the shell Located above the filter plate, the steel pipe splint is fixed on the rotating base, the rotating base on one side is fixedly connected with the transmission shaft passing through the side wall of the casing, the mo...

Problems solved by technology

[0003] The outer wall polishing device of the above-mentioned existing stainless steel pipe or steel pipe can also clean and dry the polished steel pipe outer surface through the spray pipe device installed on the lifting cover and the brush installed on the filter plate after polishing. In the actual use process, since the movable rod needs to drive the polishing pad to move on the surface of the rotating steel pipe to achieve polishing, the time for the polishing pad to move in translation to polish a complete steel pipe is related to the length of the steel pipe to be polished. When polishing a steel pipe with a certain length It takes a long time and the polishing efficiency is low, and the above-mentioned existing steel pipe outer wall polishing device drives the steel pipe splint to rotate and the movable rod to move in translation at the same time through a motor, and there will be mutual interaction between the rotation of the steel pipe to be polished and the translation of the polishing pad during polishing. Cause resistance interference, it is easy to cause the motor shaft to be overloaded and break, the energy consumption of the motor is large when it is running, the motor needs to be replaced frequently, and the use and maintenance cost is high
