The invention relates to a cold rolling and curling device for special-shaped welded pipes. A carrier roller shaft of which the axis extends in the X direction is arranged in the middle of a base, a carrier roller is installed on the middle section of the carrier roller shaft, a left stand column and a right stand column are installed on the left side and the right side of a carrier roller bracketrespectively, a left rolling roller is installed on the right side of the left stand column, a right rolling roller is installed on the left side of the right stand column, and the bottom of the leftrolling roller and the bottom of the right rolling roller are both higher than the top of the carrier roller; the bottom of the left stand column and the bottom of the right stand column are supported on X-direction sliding blocks separately, X-direction sliding block flanges on the front sides and the back sides of the X-direction sliding blocks are supported on X-direction guide rails separately, and the X-direction guide rails are fixed to the base separately; X-direction adjusting speed reducing boxes capable of enabling the left stand column and the right stand column to move left and right are installed at the left end and the right end of the base; and lifting nuts are screwed to the middle sections of Z-direction adjusting screws in the left stand column and the right stand column, the lifting nuts are fixed into Z-direction sliding blocks, and the left rolling roller and the right rolling roller are installed in concave arcs of the corresponding Z-direction sliding blocks andcan rotate in the sliding block concave arcs. According to the cold rolling and curling device for the special-shaped welded pipes, various special-shaped welded pipes with asymmetric sections can berolled.
Description
technical field [0001] The invention relates to a welded pipe manufacturing equipment, in particular to a special-shaped welded pipe cold-rolling crimping device, which belongs to the technical field of plate cold-rolling equipment. Background technique [0002] The straight seam high-frequency welded steel pipe is welded by coiling the steel strip. The width of the steel strip is equal to the circumference of the steel pipe. Then, the pipe seams are welded by high-frequency induction heating to obtain welded steel pipes. Special-shaped pipes with different cross-sections can be obtained by exchanging various rolls with different specifications. [0003] In the process of cold-rolling and curling the steel strip into a welded pipe cross-section, the two sides of the steel strip need to be bent upwards according to the required curvature. After bending, the edges on both sides are close to each other until they are spliced together. After the splicing seam is welded, a str...
