A steel pipe polishing equipment that simultaneously polishes inside and outside

Abstract

The invention relates to a steel tube polishing device allowing interior and exterior simultaneous polishing. The device comprises a base, fixing rails, a first motor, a three-jaw chuck, a supporting frame, a rotating shaft, polishing belts, idler wheels, a first fixing plate, a second motor, a first grinding wheel, a second fixing plate, a third motor, a second grinding wheel and a steel tube. The fixing rails are arranged on the base, the first motor is arranged above the fixing rails, the three-claw chuck is connected with the first motor, the supporting frame is arranged on the three-claw chuck, and one end of the rotating shaft is fixed to the three-claw chuck. The polishing belts are arranged on the supporting frame, the idler wheels are arranged on the lower portion of the supporting frame, the first fixing plate is arranged at the end of one fixing rail, the second motor is arranged on the first fixing plate, and the first grinding wheel is connected with the second motor. The second fixing plate is symmetrical about the first fixing plate, the third motor is arranged on the second fixing plate, the second grinding wheel is connected with the third motor, and the steel tube is located between the first grinding wheel and the second grinding wheel. A third grinding wheel is arranged at the end of the rotating shaft. The steel tube polishing device allowing interior and exterior simultaneous polishing has the advantages of being good in polishing effect, high in polishing precision, low in machining cost and high in machining efficiency.

Description

technical field [0001] The invention relates to a steel pipe polishing equipment which simultaneously polishes the inside and outside. Background technique [0002] Steel pipes are items that can be seen everywhere now. Because the steel pipes are hollow inside, the cost of raw materials during production is relatively low, and the steel pipes are strong in bearing pressure and beautiful in appearance, and are used in more and more fields. Although the raw material cost of the steel pipe is relatively low in production, the surface of the steel pipe is very rough after processing and forming. If it is not polished, it will not only affect the use, but also affect the appearance, and it is easy to rust; External polishing) and internal polishing (polishing inside the steel pipe), most of the existing steel pipe polishing equipment on the market separate the internal polishing and external polishing, so that two processes are required, which does not reduce the processing Eff...

Problems solved by technology

Although the raw material cost of the steel pipe is relatively low in production, the surface of the steel pipe is very rough after processing and forming. If it is not polished, it will not only affect the use, but also affect the appearance, and it is easy to rust; External polishing) and internal polishing (polishing inside the steel pipe), most of the existing steel pipe polishing equipment on the market separate the internal polishing and external polishing, so that two processes are required, which does not reduce the processing Efficiency increases the processing cost and indirectly increases the labor intensity; in addition, most of the existing polishing equipment uses grinding wheels to polish the steel pipe once, and the strength of the grinding wheel is difficult to control when polishing. The polishing is easy to cause excessive polishing, resulting in damage to the steel pipe or the reduction of the thickness, reducing the bearing pressure, etc., so the grinding wheel can only perform rough polishing during polishing, and if there is no other polishing operation in the follow-up, the polishing cannot be guaranteed.
