Description
Technical field
The utility model relates to a kind of pipe machining equipment, particularly a kind of bending machine.
Background technology
Bend pipe is one of important composition component of pipe-line, and long-distance transmission pipeline needs a large amount of bend pipes.Bend pipe is also carry one of comparatively harsh structural member in pipeline.In the pipeline of built operation, the Pipeline Failure accident relevant with bend pipe occupies quite high ratio in whole pipeline accident, and the comprehensive quality of bend pipe is one of bottleneck of restriction pipeline safety even running.
Induction heating syphon production technology fully use eddy-current heating have heating rapidly, narrow, the fast cooling feature in heating tape, compared with other method, induction heating syphon method has that ovality is little, wall thickness reduction is minimum and the plurality of advantages such as bending radius is easy to adjust, intermediate frequency hot pushing bent tubes technique is the most cost-effective one in existing various bent tube technique.Adopt Frequency Induction Heating, avoid the even phenomenon of bend pipe wall unevenness that bend pipe chimb tube wall tension when traditional bent tube technique is shaped is thinning, concave edge wall compression thickens and causes.
Its weak point is: the pipe after induction heating circle heating is in the process of being out of shape around main axis, because the pipe after heating can not be cooled in time, and stress distribution is uneven in BENDING PROCESS, thus the evenly bending of pipe fitting can not be ensured, larger flexural deformation is locally there is once have, the intensity of this position will decline fast, cause this local, position crumple distortion in BENDING PROCESS, thus have a strong impact on the qualification rate of pipe fitting.
Utility model content
The purpose of this utility model is to provide a kind of light-wall pipe elbow processing device, and its structure is simple, saves manufacturing cost, ensures the bending quality of bend pipe.
The purpose of this utility model is achieved in that a kind of light-wall pipe elbow processing device, comprise frequency heating device, described frequency heating device comprises be welded induction heating circle together and outer cooling ring, the inside of described outer cooling ring is provided with water annulus, the inner peripheral surface of outer cooling ring offers some water holes be connected with cooling water channel, the center of described frequency heating device is provided with the cooling water pipe be mated, the end of cooling water pipe be provided with corresponding with described outer cooling ring in cooling ring, the periphery of described interior cooling ring offers multiple water hole be connected with cooling water pipe, the side of described frequency heating device is provided with fixture free to rotate, the front end of described frequency heating device is provided with propulsion plant, described propulsion plant comprises oil cylinder, the piston rod of oil cylinder is fixedly connected with push pedal.
During utility model works, the end of pipe from cooling water pipe is inserted in, and by the end winding support of pipe on fixture, open frequency heating device, the end that push pedal promotes pipe is controlled by oil cylinder, it is made to move in frequency heating device, induction heating circle in frequency heating device heats it, the rotation of fixture is coordinated to realize the buckling work of pipeline, coordinate cooling ring in cooling water pipe end to realize the cooling of pipe with the outer cooling ring that induction heating circle welds together, ensure that the quality of bend pipe.Compared with prior art, the beneficial effects of the utility model are, cooling device and induction heating circle integrate by the utility model, simplify the structure, and integral structure make install time more convenient, save installation cost, the type of cooling of interior fit on, ensure that the quality that bend pipe manufactures.The utility model can be used in the manufacture of bend pipe.
In order to make the charging of pipe convenient, precision is higher, and the front end of described frequency heating device is provided with organizes directive wheel more.
In order to ensure the stability of push pedal in progradation, described push pedal center is provided with circular interior concave station.
In order to ensure the stability of push pedal work further, described oil cylinder is provided with a pair.Control push pedal action by a pair oil cylinder, that avoids it to produce in progradation rocks simultaneously.
