Stainless steel tube weld joint polishing device and use method thereof

Abstract

The invention provides a stainless steel tube weld joint polishing device and a use method of the stainless steel tube weld joint polishing device. The stainless steel tube weld joint polishing devicecomprises a gearbox, a supporting plate and a tensioning rod. A motor is arranged at one end of the gearbox. The end, far away from the gearbox, of the motor is provided with a power line. One side of the motor is provided with a power switch. The end, far away from the motor, of the gearbox is provided with a rotating shaft. The end, far away from the gearbox, of the rotating shaft is provided with a third roller. One side of the gearbox is provided with the supporting plate. The side, far away from the gearbox, of the supporting plate is provided with a protective cover. The upper portion of the supporting plate is provided with a handle. According to the stainless steel tube weld joint polishing device, small-sized integrated design is adopted, a user can hold the handle and the motorby hands and turns on the power switch to enable the motor to be electrified and operate, abrasive paper is driven to rotate, and then a weld joint can be polished; and the stainless steel tube weld joint polishing device is small in size, light in weight and suitable for conducting the weld joint polishing operation small in machining amount in a small-space machining place.

Description

Technical field [0001] The invention relates to the technical field of stainless steel pipe welding seam grinding, in particular to a stainless steel pipe welding seam grinding device and a use method thereof. Background technique [0002] Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used to produce various conventional weapons, barrels, shells, etc. Stainless steel pipe is a kind of economical cross-section steel. It is an important product in the steel industry. It usually accounts for about 8%-16% of the total steel. It has a wide range of applications in the national economy. Because the steel pipe has a hollo...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a stainless steel pipe weld grinding device and its use method, which solves the problem that the above-mentioned existing stainless steel pipe weld grinding technology mostly uses an automatic weld grinder to process stainless steel pipe profiles in Grinding is carried out in batches before leaving the factory, but in the subsequent use of stainless steel pipe profiles, it is still necessary to grind the re-generated weld seam according to the processing requirements, and the automatic weld seam grinding machine is large in size and is not suitable for on-site processing with small space and small processing volume.
