Problems solved by technology

The threading machine composed of this mechanism cuts the thread of the pipe. Because the material fiber of the cut part is cut off, the original cross section is reduced, resulting in the tensile strength of the threaded joint of the pipe being much lower than that of the connected pipe. Tensile strength, and the sealing performance of the pipe thread processed by cutting is not good when the pipe is connected. It is often necessary to use other auxiliary materials for sealing, which increases the cost of use and is subject to certain restrictions on use.

Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the drawings: the pipe thread rolling machine of the present invention is an improvement on the original pipe threading machine, as shown in the figure. It is composed of a machine base 1, a motor on the machine base, a reducer, a guide post positioning mechanism, and a workpiece clamping mechanism. On the upper side of the machine base 1, there are two sliding guide posts 2 mounted on the guide post positioning mechanism. The carriage 3 is provided with a thread rolling mechanism with a rolling wheel 4 inside. The thread rolling mechanism includes a flat spiral disk 5 which is fixed on the carriage 3. The plane spiral plate 5 is radially arranged with three inner ends of adjustable moments at a central angle of 120 degrees with a roller frame 6 each equipped with a rolling wheel 4; the plane spiral plate 5 can control the radial in and out of the three roller frames 6 , To adapt to different sizes ...

Abstract

The invention is a pipeline thread rolling method and the roller, nipping the pipeline on the pipe nipping mechanism driven by the electric machine, there is a thread rolling mechanism placed in the working front, there are rolling wheels in the rolling mechanism, the pipeline rotates and enters in between three rolling wheels coaxially and distributed at 120 deg. central angle in the thread rolling mechanism, rolling into a thread shape, the pipeline thread roller is composed of base, electric machine, reducer, guide pile locating mechanism and workpiece clamping mechanism, there is a sliding frame on the two guide piles and the there is a thread rolling mechanism set on the sliding frame, compared with existing techniques, it has the characters of reasonable structure, smooth thread, high precision, etc.

Description

Technical field [0001] The invention relates to a method for rolling a pipe to make a pipe thread and a device applying the method, belonging to a pipe machining method and device. Background technique [0002] In the prior art, most of the thread processing of pipes adopts cutting and forming methods, and the equipment applying this method includes conventional threading machines and the like. The structure of the threading machine is generally composed of a base, a motor, a reducer, a profiling cutting head, a guide post positioning mechanism, a workpiece clamping mechanism, and a feeding mechanism. The threading machine composed of this mechanism cuts the threads of the pipeline. Because the material fibers of the cut processing parts are cut, the original cross-section is reduced, resulting in the tensile strength of the threaded joint of the pipeline being much lower than that of the connected pipeline. Tensile strength, and the sealing performance of the cut pipe threads is...
