Automatic groove cutting machine for galvanized steel pipe processing

Abstract

The invention relates to an automatic groove cutting machine for galvanized steel pipe processing. The automatic groove cutting machine for the galvanized steel pipe processing comprises a base plate,a support frame, bearing devices, a mold closing device and a cutting device, wherein the upper end of the base plate is provided with the support frame, the bearing devices are symmetrically arranged outside the support frame, the bearing devices are arranged on the base plate, and the mold closing device is arranged between the two bearing devices. The automatic groove cutting machine can solvethe problems that the existing equipment cannot cut a V-shaped connection joint when cutting the groove of the galvanized steel pipe, and the steel pipe is easy to occur crack, breakage and other phenomena after the subsequent welding is completed, and the material waste is caused by unstable welding; meanwhile, the existing equipment cannot cool a saw blade when the saw blade cuts the steel pipe, and the saw blade is easy to deform, which leads to cutting failure; moreover, the existing equipment cannot guide the saw blade when cutting, the saw blade is easy to occur displacement deviation,the cutting accuracy is reduced, and the cutting machine is not conducive to the subsequent welding treatment and other difficult problems.

Description

technical field [0001] The invention relates to the technical field of bevel cutting of steel pipes, in particular to an automatic bevel cutting machine for processing galvanized steel pipes. Background technique [0002] The groove refers to the groove of a certain geometric shape that is processed and assembled into the part of the weldment to be welded. The groove is mainly used to weld the workpiece and ensure the degree of welding. According to different needs, the groove can usually be divided into X-shaped groove, V-shaped groove, U-shaped groove, etc., but most of them require a certain blunt edge. [0003] At present, when cutting the groove of galvanized steel pipe, there are usually the following deficiencies: 1. The existing equipment cannot cut out the V-shaped joint. After the subsequent welding is completed, the steel pipe is prone to cracks and fractures, and the welding is not firm. 2. The existing equipment cannot cool down the saw blade when the saw blade...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that the existing equipment cannot cut out the V-shaped joint when cutting the groove of the galvanized steel pipe. After the subsequent welding is completed, the steel pipe is prone to cracks and breaks, and the welding is not firm, resulting in waste of materials. Simultaneously, the existing equipment cannot cool down the saw blade when the saw blade cuts the steel pipe, and the saw blade is prone to deformation, resulting in failure of the cutting process, and the existing equipment cannot guide it when the saw blade cuts, which is easy to use The displacement deviation of the saw blade reduces the accuracy of cutting, which is not conducive to the subsequent welding process and other problems
