Embodiment Construction

[0014] figure 1 Among them, the thin-wall tube rolling compression forming machine includes a frame 8 on which three hollow fixed frames 9 are arranged to form a three-stage processing structure, namely, three stages I, II, and III. On the fixed frame 9, the driving device of the bending forming wheel 6 and the limiting and constraining wheel 7 is alternately arranged, and the bending forming wheel 6 and the limiting and constraining wheel 7 are located inside the fixed frame on the frame 9 and connected with the driving device. The hollow fixed frame is a regular polygon, and the driving device of the bending forming wheel 6 and the limit constraint wheel 7 is arranged in the middle of each side of the fixed frame, and the bending forming wheel 6 and the limit constraint wheel 7 are vertically arranged with the side and point to the multi-deformation In the center, the bending forming wheel 6 is a circular wheel, and the limit constraint wheel 7 is provided with a concave sur...

Abstract

A rolling shaper for decreasing the diameter of thin-wall pipe is composed of machine frame, one or more hollow frames fixed on said machine frame, the alternatively arranged on shaping rollers and limiting rollers, and the driver of said rollers.

Description

technical field [0001] The invention belongs to the field of thin-walled tube rolling and reducing diameter forming machine devices, in particular to a thin-walled tube rolling and reducing diameter forming machine. Background technique [0002] Due to long-term use, underground pipelines will rust or crack. The current common practice is to replace the pipeline as a whole. The problem with this approach is that construction is not only slow, but also expensive. Invention content: [0003] The object of the present invention is to solve the problems existing in the prior art, and provide a thin-walled pipe rolling and reducing diameter forming machine for pipeline construction, which has the characteristics of simple operation, light weight and suitable for field work. [0004] The technical solution of the present invention is: a thin-walled tube rolling and reducing diameter forming machine, which is characterized in that it includes a frame, one or more hollow fixed fr...
