[0002] Spiral steel pipe is a kind of steel product widely used in the fields of construction, bridges, pipelines, etc. In the production process of spiral steel pipe, forming and welding are two key process links. In order to improve production efficiency and product quality, it is necessary to design a spiral steel pipe forming and welding device that can accurately control the height of the guide wheel seat.

[0003] The existing spiral steel pipe forming is carried out by conveying the steel plate to the guide wheel with an inclined surface, so that the steel plate is gradually bent and turned into a spiral steel pipe shape, and then the spiral steel pipe forming part is welded. However, the guide wheel is fixed and cannot be adjusted, so that the contact surface of the guide wheel is small or does not contact the steel plate being formed, resulting in the steel plate being unable to obtain uniform bending force during the forming process, resulting in uneven stress distribution, causing local deformation, warping or cracking of the product, thereby affecting the overall quality of the spiral steel pipe.

[0034] Working principle:

[0035] The steel plate being transported enters the forming machine body 100. Since the forming machine body 100 has multiple guide wheel seats 102, the steel plate enters multiple guide wheel seats 102, which indirectly causes the steel plate to bend gradually. However, the bent ends of some steel plates do not contact some of the guide wheel seats 102. First, the personnel pulls the pull block 206 to separate the pull block 206 from the gear 2 201. Then, by rotating the drive button 202, the gear 1 207 drives the rack plate 209 in the adjustment shell 103, indirectly causing the rack plate 209 to move upward, thereby driving the guide wheel seat 102, so that the guide wheel seat 102 contacts the bent end of the steel plate, so that the spiral steel pipe is subjected to uniform and stable guiding force. The welding machine 101 works to weld the formed steel plate externally into a spiral steel pipe.
