Automatic steel pipe interior and exterior integrated grinding system

Abstract

The invention relates to steel pipe precise machining equipment, in particular to an automatic steel pipe interior and exterior integrated grinding system. The synchronous grinding of the inner wall and the outer wall of a steel pipe is achieved, moreover, due to the rotating of the steel pipe, the circumferential speed difference of rotation of the steel pipe and rotation of a steel pipe outer wall grinding device and a steel pipe inner wall grinding device is increased, and the grinding efficiency is greatly improved. The automatic steel pipe interior and exterior integrated grinding systemcan be suitable for grinding of steel pipes with different pipe diameters, and it does not need to change a grinding head. Meanwhile, the automatic steel pipe interior and exterior integrated grindingsystem is simple in structure, low in cost and high in grinding efficiency and greatly meets the production requirements of steel pipe grinding.

Description

technical field [0001] The invention relates to a steel pipe finishing equipment, in particular to an automatic grinding system integrating the inside and outside of a spiral steel pipe. Background technique [0002] The application of steel pipes is very extensive, so the production volume is very large, and some steel pipes have a relatively large individual mass, so they must be stacked outdoors, but this will inevitably be exposed to the sun and rain, so the problem of rust has always plagued the steel pipes. Time and conditions apply. Moreover, in the production process of steel pipes, such as spiral steel pipes, the limitations of the production process require grinding and polishing. Manual grinding is not only inefficient, but also requires experienced workers to operate. Therefore, the market needs a grinding device with simple structure, low cost and high grinding efficiency. [0003] In the prior art, the size of the grinding wheel on the grinding machine for t...

Problems solved by technology

The derusting device utilizes the air hole provided on the shaft head of the derusting drive shaft, which can promptly and effectively blow dust and other debris to the front, but the derusting device cannot be applied to derusting the inner wall of steel pipes with different diameters.

[0004] In the prior art, the device for polishing the outer wall of the steel pipe is also limited by the structure, and can only be used for polishing the outer wall of the steel pipe with a fixed diameter. For example, the patent with the publication number CN203738557U discloses a polishing device for the outer wall of the steel pipe. The composition includes a bracket, a platform is set on the bracket, a rotating cylinder is arranged on the platform, bearings are provided at both ends of the rotating cylinder through bearing seats, the bearing seats are fixed on the platform, steel brushes are arranged on the inner wall of the rotating cylinder, and the middle part of the rotating cylinder is There is an arc track, and a turntable is set under the arc track, and the turntable is connected to the rotating motor, and the turntable and the arc track are connected by a belt; one side of the turn drum is equipped with a hydraulic cylinder, and the end of the hydraulic cylinder of the hydraulic cylinder is provided for connecting Steel pipe fixing mechanism, conveying rollers are arranged on both sides of the platform

However, this device cannot be applied to rust removal on the outer wall of steel pipes with different pipe diameters

[0005] As end customers have higher and higher requirements for the surface quality of steel pipes, they often encounter polishing requirements on the inner and outer walls of steel pipes. The existing polishing machine cannot move forward and backward when polishing the inner wall of steel pipes. The equipment is too complicated and the work efficiency is low. The product Low quality, low security and reliability

In addition, in the prior art, although there is a device suitable for grinding the outer wall or inner wall of the steel pipe, there is no device that can simultaneously grind the inner wall and the outer wall of the steel pipe

The existing steel pipe grinding and polishing device can no longer meet the needs of production
