Forming equipment and method for double-sided submerged arc welding steel pipe

Abstract

The invention discloses forming equipment and method for a double-sided submerged arc welding steel pipe, belongs to the technical field of high-end equipment, and aims to solve the problems that the pressing position is inaccurate and a steel plate cannot be greatly curled due to the fact that an existing rolling forming machine cannot carry out double-side-edge positioning material pushing; in the material feeding and pushing process, manual control is needed, so that the automatic intelligent effect of equipment is low, and full-automatic intelligent control cannot be achieved. A steel plate is pushed into the feeding opening to be fed and matched with the bending forming device, bending of the steel plate is achieved, the pushing accuracy is improved, the bending efficiency is improved, the bottom end of an arc-shaped groove is inserted into the lower portion of a feeding roller shaft, bottom end pushing can be conveniently conducted on the pressed and formed face of the steel plate, the arc-shaped groove corresponds to the arc-shaped face of the steel plate, and the pressing forming efficiency is improved. The stability during material pushing is improved, instability of a steel plate is prevented, the inner diameter of the pressed steel pipe is effectively detected, the pressing quality is conveniently monitored, the accuracy of steel pipe pressing forming is improved, and the production quality is improved.

Description

technical field [0001] The invention relates to the technical field of high-end equipment, in particular to a forming equipment and a method for a double-sided submerged arc welded steel pipe. Background technique [0002] In the production process of double-sided submerged arc welded steel pipe, the two edges of the steel plate are firstly milled on both sides by an edge milling machine to achieve the required plate width, parallelism of the plate edge and groove shape. Bending, so that the edge of the board has the required curvature, and the forming machine is used for crimping. [0003] In the prior art, for example, a U-shaped mold for a straight seam submerged arc welded steel pipe with publication number CN206810969U includes an upper mold and a lower mold installed in a U-shaped machine; the upper mold is composed of an upper mold head and a mold handle, The upper die head is connected with the lifting beam on the top of the gantry of the U forming machine through t...

AI Technical Summary

Problems solved by technology

[0005] 1. In the existing technology, workers are required to control the process of material feeding and pushing, which leads to low automation and intelligence effect of the equipment, and it is impossible to realize fully automatic intelligent control;

[0006] 2. The existing roll forming machine cannot perform double-sided positioning and pushing, resulting in inaccurate pressing positions, and the fixed-curved pressing plate cannot make the steel plate curl greatly;

[0007] 3. Secondly, after the existing steel pipes are rolled, it is impossible to detect the curvature of the inner wall, resulting in inconsistent pressing curvature of each group of steel pipes, which affects later use
