Description

technical field [0001] The invention relates to a hydraulic grooving machine, in particular to a grooving machine in which the main body and frame of the machine can be rotated, and the frame can be folded up and down. The ring groove is rolled on the inside to install the ring pipe clip, so as to achieve the purpose of quickly installing the pipe. It belongs to the equipment for pipe installation in building construction. Background technique [0002] In housing construction, water supply and drainage pipelines need to be installed, and the two pipes in the pipeline need to be connected to each other. The traditional technology usually uses flange connection. The flange connection needs to be welded and fixed with fasteners. The construction is cumbersome, sparks will be generated, and fasteners such as screws are easy to loosen. Therefore, in recent years, a rolling grooving machine has been developed, which rolls out an annular groove on the end of the pipe, and installs...

AI Technical Summary

Problems solved by technology

But existing grooving machine has following shortcoming: the one, main body (comprising power and grooving mechanism) is fixed with frame, because some pipes are relatively long (as 5, 6 meters long), need to be assisted at the other end of pipes Bracket support, because the position of the bracket is not easy to align, the pipe and the machine are in an inclined state, and because the long pipe itself has problems such as deformation or bending, the length and weight of the pipe when the machine is working makes the machine unable to control the correct position, and the workpiece cannot be positioned correctly. It is easy to run the tube, and the processed parts are unqualified; second, the frame of the rolling groove machine is a fixed bracket, and the height cannot be adjusted. It has poor adaptability to different groups of people, and the operation is laborious. It is labor-intensive and time-consuming; the third is that due to the large size difference of the pipe material, the stroke of the oil cylinder of the rolling groove machine cannot be adjusted, the processing limitation is large, and in some cases there are more useless strokes, and the work efficiency is low
