Description
Technical field
The present invention relates to the pipe bending technique field, relate in particular to a kind of adjustable bending machine that is used for the thick tube wall pipe of big caliber.
Background technology
At present in various structural steelworks; The making of bend pipe generally is to adopt the mold punch forming, after pipe is curved required curvature, is placed in the ready-made mold again; Correct; Such engineering is got off, and the mold of rectification possibly need several thousand symbols, possibly also will use fire roasting to some immedicable bend pipes.
For example application number is 2009201867371, and name is called the Chinese invention patent of " large-caliber small-bend radius medium frequency bending of pipe machine ", can bend elbow with great caliber and small bending radius; But exist the scope of application wide inadequately; Relatively targetedly, can not extensively promote, can not adjust in good time.And for example application number is 201120101197X, and name is called the Chinese invention patent of " multifunctional pipe bending machine ", to the problem of straight tube discontinuity in the process that bends; This piece can make that a more than position receives the onward impulse from driving wheel on the straight tube, and the course of work is more stable, and workpiece can level be placed; Security is good; Be convenient to measurement and bend precision, when member bends above regulation curvature, also can easily the reverse bending of member be corrected.Though solved stability and curvature control problem in the bend pipe process to a certain extent, but still can not be applicable to the pipe of big caliber.
In structural steelwork to the making of large-size net rack; Especially to the pipe of some big calibers and thick tube wall, do not have the plant equipment of specialty that it is carried out bending now, and the angle of bend of every steel pipe is all inconsistent; All need adjust the layout of moulding bed when every bend pipe being made according to conventional method; Therefore to general heavy construction project, adding up to needs No. nearly ten thousand moulding beds of adjustment, needs the manual work and the section bar of labor.At present in the process of structure steel fabrication operation, the making of bend pipe is to bake or be to use the mold punching press with fire, and the bend pipe of making has so not only destroyed the mechanical property of steel; And the pipe error of curvature of bending out is bigger; Because curvature is too many, pipe not of uniform size, as operate incorrect; Be prone to cause the damage of pipe even the subscription rate of pipe, the operant level of clod wash is had relatively high expectations; For different pipes, curvature is different during owing to bending, and the punching press mold on the forming mill will be done continuous adjustment, the promptly time-consuming material that takes again; For the curvature of control valve, need make the moulding mold, promptly need very big place, cause the very big waste of steel again.So not only workload is big, has wasted a large amount of funds, and operating efficiency is also extremely low.Therefore developing a kind of different tube diameters that adapts to is considerable with the forming mill that bends to different curvature.
Summary of the invention
The purpose of this invention is to provide the adjustable bending machine of a kind of big caliber; Through adopting two groups of hydraulic jack, can realize increasing work efficiency and reducing cost, avoid the traditional cold bending method to need too many mold; Save the work of making mold and rectification, greatly reduced the consumption of material.
In order to realize above-mentioned purpose of design, the scheme that the present invention adopts is following:
The adjustable bending machine of a kind of big caliber; Comprise that big caliber pipe, rectangular frame bearing, hydraulic jack and moulding use the small-sized hydraulic jack, wherein, the rectangular frame bearing laterally arranges on the ground; Be used to support the member of wanting bend pipe; Its long margin frame is made up of I-steel, and I-steel is provided with corresponding perforate, and big caliber pipe passes perforate and movable two long margin frames that are horizontally through the rectangular frame bearing.The purpose that rectangular frame punches on framework is the pipe ability freely-movable in order to be bent.
Preferably, hydraulic jack is 300 tons of hydraulic jack, and 300 tons of hydraulic jack are that bend pipe provides power source.
Preferably, hydraulic jack has the control system.The control systemic effect is: the one, in order to control the stroke of large hydraulic jack, the 2nd, in order to control the small-sized hydraulic jack so that produce the curvature of required bend pipe.
Preferably, the rectangular frame bearing horizontal edge frame is provided with two hydraulic jack.
Preferably, four moulding are arranged on the small-sized hydraulic jack on another horizontal edge frame of rectangular frame bearing, are oppositely arranged with two hydraulic jack.
Preferably, also comprise sliding rail and jack dolly.
Preferably, when making the bending machine model, can use steel watt replacement in the end of hydraulic jack.
Preferably, also comprise the low each other sterilizing system of top power.
Preferably, two the said sliding rails that laterally arrange in the long margin frame inboard of rectangular frame bearing.
Preferably, the jack dolly is arranged on the outside of rectangular frame bearing, realizes moving the big caliber pipe that will be bent.
The adjustable bending machine of big caliber of the present invention comprises the combination in any of above various features.
Beneficial effect of the present invention is:
1. can carry out clod wash to the pipe of different tube diameters and different curvature, can save the expense of moulding bed in a large number;
2. operating personnel are not had specific (special) requirements, general workman can operate;
3. be a cold roll forming, need not add other molds and fix;
4. during clod wash, do not stay straight flange, can save material greatly;
5. can realize continuous productive process, increase work efficiency greatly.
