Abstract

The invention discloses a device for removing inner burrs in a high-frequency straight seam resistance welding steel tube centrifugal wire. The device comprises a base, a steel tube fixing device, driving trolleys, a connecting rod and a grinding head component; the steel tube fixing device is arranged on the base; the driving trolleys can be movably arranged on the base; and the grinding head component and the driving trolleys are respectively connected with two ends of the connecting rod. The device is used for removing the inner burrs in the high-frequency straight seam resistance welding steel tube centrifugal wire. After a centerline of a steel tube welding seam is fixed on the steel tube fixing device, a grinding head motor is started up; the driving trolleys on two ends of the steel tube are respectively started up at an interval of one to two minutes; and a grinding head is driven to enter the steel tube for grinding by the connecting rod. The device has high working efficiency, high precision of inner burrs removal, convenient operation and low operation cost; a Fermi level ceramic grinding medium is selected to be made into a grinding belt which is provided with an ultra coating layer; and the grinding belt has self-cooling function in grinding and can carry out strong grinding and can not burn a workpiece.

Description

【Technical field】 [0001] The invention relates to the removal of burrs in high-frequency straight seam resistance welded steel pipes, in particular to an off-line internal burr removal device for high frequency straight seam resistance welded steel pipes. 【Background technique】 [0002] The internal burrs produced in the production process of ERW straight seam welded pipes have a serious hindering effect on the transportation of oil and gas. Domestic and foreign standards have clear requirements for internal burrs of low-pressure fluid delivery pipes and oil and gas industry pipes such as long-distance pipelines and oil well casings. People have also been constantly exploring more advanced methods and tools for removing internal burrs. [0003] The current large-diameter ERW units are equipped with an online deburring device to remove the internal burrs online. Some advanced ERW production lines are also equipped with UT ultrasonic burr monitors. However, the working envi...
