The set has the advantages that the stability is good, the constraint property is good, the working efficiency is high, and the cost is saved.

Description

technical field [0001] The invention relates to the field of reducing the diameter of metal pipes, in particular to a high-stability welded pipe unit. Background technique [0002] The forming of metal pipes generally requires a series of processes such as forming, welding, deburring, and diameter reduction to form. During this process, the following problems are prone to occur: [0003] During the forming process, it is necessary to overcome the problem of equipment stability, because most of the existing forming welded pipe machines are driven by couplings. The bottom end of the vertical shaft in the vertical roller is fitted with a screw rod and then slidably installed in the housing. The gland restricts the vertical shaft Limited, there is also an assembly gap between the housing and the vertical shaft, and there is also a gap between the threaded fit of the screw rod and the vertical shaft. The three gaps can easily cause the offset and shaking of the two vertical rolle...

AI Technical Summary

Problems solved by technology

[0003] During the forming process, it is necessary to overcome the problem of equipment stability, because most of the existing forming welded pipe machines are driven by couplings. The bottom end of the vertical shaft in the vertical roller is fitted with a screw rod and then slidably installed in the housing. The gland restricts the vertical shaft Limited, there is also an assembly gap between the shell and the vertical shaft, and there is also a gap between the screw thread and the vertical shaft. The three gaps can easily cause the two vertical rollers to shift and shake in the horizontal and vertical directions.

It leads to poor stability of the equipment, and there is a problem of insufficient stability when preparing high-performance metal pipes

[0004] In the process of deburring, the tools currently used are all ordinary tools. The blade on the tool is a straight chisel edge. Since the chisel edge is in point contact with the weld seam of the welded pipe, only one point on the tool is worn, and the other parts are not. Use, but still need to replace the tool after the point is worn, resulting in tool waste

[0005] There is a design plan to modify the tool clamping device to maximize the use of the tool by adjusting the position of the tool clamp, but the tool clamp has stability requirements, and the cost and difficulty of the modification are high

[0006] During the reduction process, the general reducing unit can operate normally when the degree of diameter reduction is not high, but when the degree of diameter reduction is high and the formed pipe is thin, the pipe is easily deformed, resulting in upturning or Side deviation, affecting the continuity of diameter reduction
