Double-side automatic R arc edge milling machine for helical weld pipe production line

Abstract

The invention discloses a double-side automatic R arc edge milling machine for a helical weld pipe production line. The double-side automatic R arc edge milling machine comprises a milling machine, afacing cutter head, upper limiting rolling wheels, a blow pipe and a milling machine adjusting device. The facing cutter head is mounted at the bottom of the milling machine. The upper limiting rolling wheels are connected with a first adjusting bolt. The blow pipe is mounted in the position, located beside the upper limiting rolling wheels, of the inner wall of a shell. A guide rail is connectedwith the lower end face of a plate body. The side edge of the plate body is connected with plate limiting wheels. According to the double-side automatic R arc edge milling machine for the helical weldpipe production line, the novel structure design is adopted; compared with a traditional double-side automatic R arc edge milling machine, the double-side automatic R arc edge milling machine can conduct stable limiting and fixation on a plate to avoid the influence on the machining precision when the plate slides up and down or makes contact with the facing cutter head and shake left and right in the machining process. Meanwhile, the structure with the metal scrap cleaning function is designed, and the surface of the plate is protected against damage in the follow-up machining and transferring process.

Description

technical field [0001] The invention relates to the technical field of diving equipment, in particular to a bilateral automatic R-arc edge milling machine for a spiral welded pipe production line. Background technique [0002] Spiral welded pipe is made by rolling a steel plate into a tube blank according to a certain helical angle, and then welding the pipe seams. Before curling the plate, it is necessary to mill the two sides of the plate. When you need to use bilateral automatic R arc edge milling machine. [0003] With the continuous edge milling of the plate, the traditional double-sided automatic R-arc edge milling machine cannot stably limit the plate due to the unreasonable structural design during the processing process. The generated metal waste should be cleaned up. The accumulated metal waste will cause scratches, dents and deformation on the surface of the plate, and even cause the automatic transmission to be stuck. Therefore, it is necessary to design a bila...
