TECHNICAL FIELD

[0001] The present application relates to the technical field of seamless steel pipe production equipment, and more particularly to a seamless steel pipe surface rust peeling device. BACKGROUND

[0002] A seamless steel pipe refers to a steel pipe made of a whole round steel and having no weld on the surface. In the production process of the seamless steel pipe, rust on the surface of the steel pipe or residual oxide layer can cause many problems. The rust on the surface of the steel pipe can affect the accuracy of flaw detection, causing deviation in the detection of internal defects of the steel pipe; and can also cause the paint layer to not be normally attached when the steel pipe is painted, affecting the appearance and protection performance of the steel pipe. Therefore, the rust of the seamless steel pipe needs to be handled in time.

[0003] In actual production, the seamless steel pipe mainly adopts a physical rust removal method. The traditional physical rust removal method relies on manual operation and removes rust manually by rubbing with a steel brush and a steel knife, which is time-consuming and laborious and has extremely low rust removal efficiency. In addition, in the rust removal process, it is difficult to collect the rust after peeling, which increases the unnecessary burden on the workers and causes waste of human cost and time. At present, there are seamless steel pipe rust removal devices on the market, which remove rust by mechanical cooperation, greatly saving human cost, reducing labor intensity, and significantly improving rust removal efficiency compared with the traditional manual rust removal. However, the existing seamless steel pipe rust removal devices still have many problems: 1. The rust removal device is inconvenient to adjust for different specifications of the steel pipe and cannot adapt to seamless steel pipes of many different specifications. 2. During rust removal, dust and scattered rust in the steel pipe are easy to accumulate on the inner wall of the steel pipe, and cleaning often needs manual operation or the rust is made to slide out by vertically standing the steel pipe, which is complicated to operate, consumes a lot of manpower, and has high human cost; the inner wall rust removal speed is slow, affecting the production efficiency. Therefore, it is urgent to develop a seamless steel pipe surface rust peeling device to solve the above problems. CONTENT OF THE UTILITY MODEL

The device comprises a base, two installation plates are arranged at the two ends of the base, a rust removal roller set is arranged between the two installation plates, the rust removal roller set comprises two horizontally arranged rust removal rollers and a first driving unit, the rotating shaft of the rust removal roller is connected with the output shaft of the first driving unit, the rust removal roller is slidingly connected with the installation plate, a steel pipe to be rusted is placed on the rust removal roller set, and the steel pipe is tangent to the two rust removal rollers; the installation plate is connected with an inner rust cleaning assembly, the inner rust cleaning assembly comprises a telescopic rod, a second driving unit for driving the telescopic rod to extend and retract, and a plurality of rust removal units arranged at the end of the telescopic rod, the telescopic rod is slidingly connected with the installation plate, and the rust removal units are in contact with the inner wall of the steel pipe.

[0005] Preferably, the sliding direction of the rust removal roller on the installation plate is a horizontal direction.

[0006] Preferably, the sliding direction of the telescopic rod on the mounting plate is vertical.

[0007] Preferably, the plurality of rust removal units are uniformly distributed on the outer wall of the end of the telescopic rod.
