Abstract
The invention discloses a mode-switchable thin-wall steel tube machining device. The mode-switchable thin-wall steel tube machining device comprises a medium-frequency heating unit. The medium-frequency heating unit comprises an induction heating ring and an outer cooling ring which are welded together. An annular water channel is formed in the outer cooling ring. A plurality of water holes communicating with the cooling water channel are formed in the inner circumferential surface of the outer cooling ring. A cooling water pipe matched with the medium-frequency heating unit is arranged in the center of the medium-frequency heating unit. An inner cooling ring, corresponding to the outer cooling ring, is arranged at the end of the cooling water pipe. A plurality of water holes communicating with the cooling water pipe are formed in the outer circumference of the inner cooling coil. A clamp capable of rotating freely is arranged on the side face of the medium-frequency heating unit. Push plates driven by oil cylinders are arranged at the front end of the medium-frequency heating unit. Each push plate comprises an auxiliary plate slidably arranged in a main plate. The auxiliary plates are provided with a plurality of circular inward-concave tables. According to the mode-switchable thin-wall steel tube machining device, the installation cost is reduced, the manufacturing quality of bent tubes is ensured through an internal-external cooperation cooling mode, and the device can be used for manufacturing the bent tubes.
Description
Technical field
The present invention relates to a kind of pipe machining equipment, particularly to a kind of bending machine.
Background technology
Bend pipe is one of important composition component of pipe-line, and long-distance transmission pipeline needs substantial amounts of bend pipe. 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 at a relatively 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 sensing heating have heating rapidly, heating tape feature narrow, fast cooling, 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, it is to avoid the even phenomenon of bend pipe wall unevenness that when traditional bent tube technique shapes bend pipe chimb tube wall tension is thinning, concave edge wall compression thickens and causes.
It is disadvantageous in that: the pipe after induction heating circle heats is in the process that main axis deforms, and owing to the pipe after heating can not be cooled down in time, and process pipeline kind is single.
Summary of the invention
It is an object of the invention to provide a kind of interchangeable pattern thin-wall steel tube processing unit (plant), its simple in construction, save manufacturing cost, applied widely, it is ensured that the bending quality of bend pipe.
The object of the present invention is achieved like this: a kind of interchangeable pattern thin-wall steel tube processing unit (plant), bag frequency heating device, described frequency heating device includes being welded induction heating circle together and outer cooling ring, described outer cooling ring be internally provided with water annulus, the inner peripheral surface of outer cooling ring offers some water holes being connected with cooling water channel, the cooling water pipe being provided centrally with being mated of described frequency heating device, the end of cooling water pipe is provided with the interior cooling ring corresponding with described outer cooling ring, the periphery of described interior cooling ring offers multiple water hole being 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 the push pedal through hydraulic oil cylinder driving, described push pedal includes being slidably arranged in daughter board in motherboard, described daughter board offers concave station in multiple circle.
When the present invention works, pipe is inserted in from the end of cooling water pipe, and the end of pipe is fixed on fixture, open frequency heating device, control push pedal by oil cylinder and promote the end of pipe, it is made to move in frequency heating device, it is heated by the induction heating circle in frequency heating device, the rotation coordinating fixture realizes the buckling work of pipeline, the outer cooling ring welded together with induction heating circle coordinates the interior cooling ring of cooling water pipe end to realize the cooling of pipe, ensure that the quality of bend pipe, this device is when process pipeline, the demand regulating daughter board position in motherboard to adapt to the processing of different size steel pipe can be passed through. compared with prior art, the beneficial effects of the present invention is, chiller and induction heating circle are integrated by the present invention, simplify structure, and integral structure is more convenient when making to install, and has saved installation cost, the type of cooling of interior fit on, ensure that the quality that bend pipe manufactures, the interior concave station being arranged on daughter board ensure that pipe stability in progradation. the present invention can be used in the manufacture of bend pipe.
So that the charging of pipe is convenient, precision is higher, and the front end of described frequency heating device is provided with organizes directive wheel more.
In order to ensure push pedal stability in progradation, the top of described motherboard is provided with lock-screw. After selected for the interior concave station position of suitable dimension, by lock-screw, daughter board is fixed, it is ensured that pipe stability in progradation.
In order to be further ensured that the stability that push pedal works, described oil cylinder is provided with a pair. Control push pedal action, it is to avoid what it produced in progradation rocks by a pair oil cylinder simultaneously.
