Description

Technical Field

[0001] This application relates to the technical field of steel pipe production equipment, and particularly to a steel pipe end-facing machine. Background Art

[0002] In modern industrial production, steel pipes, as an important basic material, are widely used in many fields such as construction, machinery manufacturing, petrochemical industry, and transportation. During the processing of steel pipes, the end-facing treatment is a key process, and its quality directly affects the subsequent use performance and connection effect of the steel pipes.

[0003] Currently, the steel pipe end-facing machine is the main equipment for realizing the end-facing treatment of steel pipes. The existing steel pipe end-facing machines usually adopt a structure in which multiple cutter heads are distributed in a circular shape to perform the grinding and end-facing operation on the steel pipes. This structural design can meet the processing requirements for the end-facing of steel pipes to a certain extent. However, there are obvious defects in actual applications.

[0004] When performing end-facing processing on steel pipes of different sizes, due to the change in the outer diameter size of the steel pipes, in order to ensure that the cutter heads can accurately and efficiently perform the grinding and end-facing treatment on the steel pipes, it is necessary to adjust the positions of multiple cutter heads so that they are on the same toroidal surface as the outer surface of the steel pipes. However, due to the large number of cutter heads and their circular distribution, during the adjustment process, not only the moving distance and angle of each cutter head need to be precisely controlled, but also the positional coordination and consistency among multiple cutter heads need to be ensured. This results in a difficult and cumbersome adjustment process, which requires a large amount of time and effort, seriously affecting the processing efficiency and production progress of the steel pipe end-facing.

[0005] In addition, the frequent and complex cutter head adjustment is likely to cause deviations in the positions of the cutter heads, thereby affecting the processing accuracy and quality of the steel pipe end-facing, increasing the rejection rate and production cost. At the same time, the complex adjustment operation also requires a high technical level and experience from the operators, increasing the working intensity and training cost of the operators.

[0006] Therefore, how to design an end-facing machine that can simply and quickly adapt to steel pipes of different sizes, reduce the difficulty and cumbersome degree of cutter head adjustment, and improve the processing efficiency and quality has become an urgent problem to be solved in the current field of steel pipe end-facing machines. Summary of the Invention

[0021] By adopting the above technical solution, before the steel pipe is placed at the fixing position of the locking component, the lifting cylinder can be controlled to drive the baffle to descend, so that the end of the steel pipe abuts against the baffle, and thus the end plane of the steel pipe is kept parallel to the end face of the mounting disc.

The extending direction of the hydraulic cylinder 51 points to the center of the circular hole, and the plurality of hydraulic cylinders 51 are used to drive the fixing block 52 to press the steel pipe against the axis of the circular hole.

[0029] Furthermore, after the steel pipe is placed in the circular hole, the hydraulic cylinder 51 can be controlled to extend, so that the plurality of hydraulic cylinders 51 drive the fixing blocks 52 to abut against the steel pipe at the same time, thereby fixing the position of the steel pipe on the axis of the circular hole.

[0030] The machine body 1 is provided with a mounting disc 2, and the mounting disc 2 is coaxially arranged with the round hole.
