A double edge milling machine for large wall thickness steel plate

Abstract

The invention relates to a large-wall thick-steel plate double-edge edge milling machine. The edge milling machine comprises an entrance conveying roller device, wherein a centering device is mounted on the entrance conveying roller device; the rear end of the entrance conveying roller device is connected with a milling device, an exit conveying roller and a surface chip removal device; and a clamping vehicle reciprocates on a track among the entrance conveying roller device, the milling device, the exit conveying roller and the surface chip removal device. The machine provided by the invention is compact and reasonable in structure and convenient to operate; the whole machine adopts full-automatic control of CNC; a console is provided with a human-machine interface for inputting the wall thickness, plate width, length and material of the steel plate; and the working parameters of each execution part of the edge milling machine are automatically determined. A power box of the edge milling machine is driven by a gear and has high rigidity and strong cutting ability; a steel plate can be conveniently guided into / out of the edge milling machine; in edge milling, the condition that a pressure roller in the middle touches the steel plate can be ensured, and the profiling effect in cutting is good; and the centering, clamping and milling of the steel plate are controlled by a servo motor, the positioning is accurate, and the groove dimensional accuracy is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe manufacturing, in particular to a double-edge milling machine for large-wall thick steel plates. Background technique [0002] In the production line of large diameter straight seam and spiral submerged arc welded steel pipes of φ508-φ1422mm, edge milling machine is one of the key equipment. Milling bevel quality and efficiency are crucial to production. With the increasing demand for large-diameter submerged arc welded pipes, the material of steel plates has been continuously improved, and the wall thickness has also been continuously increased. At present, the steel grade has reached X100, and the wall thickness of steel pipes has exceeded 50mm. The milling processing capacity of the existing edge milling machine is insufficient. In addition, due to the unstable quality of steel plate raw materials, the undulation of the steel plate surface has a great impact on the geometric size, precisio...
