Abstract
The utility model relates to a bent pipe marking device, in particular to a portable zero-damage wide angle pipe bender. The pipe bender adopts the technical proposal that: the pipe bender is mainly composed of a fixed plate and a plurality of concave wheels, the plurality of concave wheels are movably connected at the same side of the fixed plate, two of the concave wheels are closely fixed with each other, and the distance between the two concave wheels is adjustable, a pipe needing to be bent is inserted between the two concave wheels, and a bent pipe can be made by pulling the pipe leftward (rightward). The pipe bender has the advantages of: being capable of adjusting the radius of the bent pipe through adjusting the distance between the concave wheels, simple structure, low manufacturing cost, convenient operation, simple processing and fitting field operation.
Description
One, technical field:
The utility model relates to a kind of bend pipe producing device, particularly relates to a kind of portable not damaged wide-angle pipe bender.
Two, background technology:
In the construction maintenance process, the frequent change pipeline trend, particularly heating construction of needing needs continuous use to come back bending and a large amount of yaws to bend especially, and this just need carry out a large amount of elbow of welding on pipeline, also can be winding on pipeline.Winding comparing with weld ell wants fast a lot, and circulating resistance is little, for some small-bore pipeline flow processs, such as the pipeline of ∮ 15mm, ∮ 20mm, ∮ 25mm, ∮ 48mm, weldering system elbow welds with electric welding on these pipelines, because bore is less, extremely dumb, be prone to weld defect; If carry out the bend pipe operation, the general at present method that adopts is: with gas welding the pipeline heating is bent again earlier, but the problem of its existence is easily that pipe is curved flat; Certainly, can adopt yet and irritate sand and then bend pipe in pipe, still, on-the-spot execution conditions generally do not allow, and complicated loaded down with trivial details.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of easy and simple to handle, portable not damaged wide-angle pipe bender that can the quick Fabrication bend pipe.
Its technical scheme is: mainly be made up of fixed head and a plurality of recessed wheel, homonymy at fixed head flexibly connects a plurality of recessed wheels, wherein two are recessed take turns adjacent fixing, and the distance between two recessed wheels is adjustable, the pipe that needs are bent inserts between two recessed wheels, and (right side) pulled pipe and just can be bent out bend pipe left.
Preferred scheme is: described recessed the wheel is set to three, and three recessed wheels leg-of-mutton shape that meets at right angles.
In addition, described recessed the wheel by being bolted to the homonymy of fixed head, convenient on-the-spot assembly and disassembly.
The beneficial effects of the utility model are: by regulating the distance between recessed the wheel, can regulate winding radius, it is simple in structure, low cost of manufacture, simple to operation, processing is simple, be fit to execute-in-place.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is left views of the present utility model.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
Mainly take turns 2,3 and 5 and form by fixed head 1 and three are recessed, three recessed shapes of preferably forming right angled triangle of taking turns certainly, also can be other compound modes, in addition, a plurality of recessed wheels can be set also, are not described in detail in this; The recessed homonymy that is fixed on fixed head by bolt 4 of taking turns, convenient on-the-spot assembly and disassembly; Wherein two are recessed to take turns 2 and 5 adjacent fixingly, and the distance between each recessed wheel is adjustable, and the pipe of needs being played system inserts between two recessed swinging, and the moving pipe of (right side) plate just can be bent left.And it is full to bend the curved slick and sly external form that, and internal diameter is smooth to reduce local frictional resistance significantly.The pipe of same model and bending radius are different curved if desired, and it can regulate the distance between recessed the wheel easily, can regulate winding radius.The pipe of crooked different model if desired, can change different model recessed just take turns can crooked different-diameter pipe.They regulate, cooperate the winding work that just solves fully at work progress mutually.
During use, take pipe bender to scene and install on the spot, it recessed taken turns to utilize being bolted on the steel plate, a few minutes just can install, and are very convenient, quick.
Claims (3)
1, a kind of portable not damaged wide-angle pipe bender is characterized in that: mainly be made up of fixed head (1) and a plurality of recessed wheel, flexibly connect a plurality of recessed wheels at the homonymy of fixed head (1), wherein two are recessed to take turns adjacent fixingly, and the distance between two recessed wheels is adjustable.
2, portable not damaged wide-angle pipe bender according to claim 1, it is characterized in that: described recessed the wheel is set to three, and three recessed wheels leg-of-mutton shape that meets at right angles.
