Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular to an anti-deflection conveying roller device for preventing weld deflection during steel pipe diameter expansion. Background Technology

[0002] In the steel pipe manufacturing industry, diameter expansion is a key process for changing the size and specifications of steel pipes. However, during the diameter expansion process, due to various factors, the weld seam of the steel pipe is prone to misalignment, resulting in weld seam damage and alteration of mechanical properties to meet requirements. Weld seam misalignment has a significant impact on the quality of the steel pipe.

[0003] Currently, the problem of weld misalignment in steel pipe expansion mainly relies on manual adjustment by workers. This not only results in high labor intensity for workers, but also heavily depends on the experience and skills of operators, making it difficult to guarantee accuracy and failing to meet the needs of large-scale production. Utility Model Content

[0016] The beneficial effects of this utility model are:

[0017] 1. The electric adjustment mechanism uses a geared motor to drive the screw to rotate, which causes the copper nut to move the conveyor roller support mechanism along the length of the guide rail, precisely adjusting the position of the conveyor roller mechanism, and thus adjusting the position of the steel pipe weld. This replaces manual adjustment of the steel pipe weld position by workers, reduces the labor intensity of workers, ensures that the steel pipe weld is not damaged by pressure, ensures that the mechanical properties of the steel pipe meet the requirements, and ensures the processing quality of the steel pipe.

[0018] 2. The electric adjustment mechanism uses a geared motor, which can provide stable power. The speed reduction and torque increase effect of the geared motor makes the screw and copper nut transmission smoother and more reliable, thus improving the working efficiency and stability of the equipment.

[0019] 3. The conveyor roller support mechanism adopts a sliding engagement between the slide plate and the guide rail, which has a higher load-bearing capacity compared to the traditional sliding engagement between the slider and the guide rail;

[0020] 4. The two sets of conveyor roller mechanisms work together to effectively clamp the steel pipe and allow it to rotate freely during pipe diameter expansion without affecting normal processing. At the same time, the position of the steel pipe can be precisely controlled by adjusting the position of the rollers, thus achieving effective adjustment of weld seam offset.

Specifically, the nut sleeve 42 and the copper nut 24 are connected by screws.

A fourth through cover 448 is installed at the outer end of the second mounting tube 442, and a fifth sealing ring 449 is installed between the fourth through cover 448 and the drive shaft 51.

[0047] The electric adjustment mechanism uses a geared motor to drive the screw to rotate, which causes the copper nut to move the conveyor roller support mechanism along the length of the guide rail. This precisely adjusts the position of the conveyor roller mechanism, thereby adjusting the position of the steel pipe weld. This replaces manual adjustment of the steel pipe weld position by workers, reduces the labor intensity of workers, ensures that the steel pipe weld is not damaged by pressure, ensures that the mechanical properties of the steel pipe meet the requirements, and guarantees the processing quality of the steel pipe.
