Description

Technical Field

[0001] The utility model relates to the technical field of pipeline grooving, in particular to an electric hydraulic pipeline grooving machine. Background Art

[0002] Currently, the main methods for connecting large-diameter metal pipes include clamps, welding, and flanges. Compared to welding and flanges, clamps offer advantages such as no damage to the pipe's inner coating, ease of operation, reduced labor time, and zero pollution. However, clamps require a groove to be formed in the pipe using a grooving machine. The clamps then clamp the two pipes together through the groove. During grooving, the pipe must be laid flat for grooving.

[0003] According to Chinese patent announcement number: CN117884663A, an electric hydraulic pipe grooving machine includes a machine base, a frame fixedly mounted on the machine base, a plurality of support assemblies disposed on one side of the machine base, the support assemblies being used to support the pipe, a drive assembly disposed on the machine base, the drive assembly being used to drive the pipe to rotate, a clamping assembly and a grooving assembly disposed on the frame, the clamping assembly being used to press the pipe against the drive assembly, the grooving assembly being used to cut the pipe, and an injection assembly disposed on one side of the frame being used to spray cutting fluid. By arranging the machine base, frame, support assembly, drive assembly, clamping assembly, grooving assembly, and injection assembly, the effect of facilitating the formation of annular grooves on the pipe surface is achieved, thereby improving the efficiency of pipe grooving. However, when using the above-mentioned device, the purpose of grooving is achieved by rotating the pipe. However, when the pipe is too long and is rotated for grooving, the center of gravity of the pipe shifts, and the grooving position shifts, thereby affecting the grooving effect of the pipe.

[0004] Therefore, when using the above device, the pipe needs to be rotated, so that the slotting position will be offset, affecting the slotting effect of the pipe. Utility Model Content
