Description

Technical Field

[0001] The invention relates to the technical field of deburring a steel pipe port, and more particularly to a deburring device for a steel pipe port. Background Art

[0002] Steel with a hollow cross-section whose length is much larger than its diameter or circumference needs to be cut during the production process of steel pipes. Burrs are easily generated on the cuts after processing, and deburring is to remove the thorns or burrs formed at the intersection of part surfaces. At present, in order to improve the deburring efficiency of pipe ports, corresponding deburring equipment is usually required.

[0003] According to the search, the patent number CN218136937U discloses a pipe port deburring device, including a frame, on which two symmetrically distributed pressure plates are arranged, and the opposite sides of the two pressure plates are arranged as arc surfaces, and oil cylinders are fixedly installed at the four corners of one side of the pressure plate, and the output end of the oil cylinder is fixedly connected to the pressure plate and installed on the frame. A motor is arranged at the upper end of the frame, and a driving mechanism is arranged on the annular grinding block, and the driving mechanism is engaged with a plurality of driving strips. By placing the pipe in the frame, the pressure plate is driven to move toward the pipe and clamp the pipe by the oil cylinder, and the annular grinding block is driven to rotate by the motor, and the annular grinding block is connected to the plurality of grinding blocks through the driving strip and rotates synchronously, so that the plurality of grinding blocks can remove the burrs at the cut end, and by turning the direction of the pipe, the other end of the pipe is brought into contact with the annular grinding block, and the burrs on the port surface can be removed by driving the annular grinding block to rotate.

[0004] With respect to the above-mentioned related technologies, the current deburring equipment is usually of the above-mentioned form, and the pipe is deburred after being fixed. However, when facing a steel pipe with a relatively thin inner wall or a relatively large volume, when the thin-walled pipe is placed horizontally, the pressure on its lower part is greater than that on the upper part. This uneven gravity distribution will cause the pipe to become elliptical, so that the port is easily elliptical, and the port deburring operation of the elliptical steel pipe is difficult. The existing equipment usually performs deburring operations in a circular working path, which causes the steel pipe in this state to affect the normal operation of the burr. The internal support is used to rigidly support the inside of the steel pipe to restore it to a circular shape, which is easy to cause secondary deformation of the thin steel pipe due to excessive local force, affecting the subsequent use of the thin-walled steel pipe. For this reason, a deburring device for the steel pipe port is proposed. Summary of the invention
