Description
Technical field
The utility model relates to a kind of metal tube bending machining field, relates in particular to the manual pipe crimping tool of a kind of metal tube.
Background technology
Often need bend processing in the engineering at present, to meet engine request to metal tube (like steel pipe).But existing manual pipe crimping tool often needs repeatedly bend pipe, and is easy to generate curved flat and concave point.Like manual pipe bender commonly used, it has handle and handle one end is connected with elbow, and this elbow is supported and supported down by going up of connecting plate raising; Should go up support periphery and be provided with inner groovy, be supported for down cylindrical, during bend pipe with metal tube place support up and down in the middle of; Firmly realize bend pipe to pressing down handle; But owing to be supported on down stressed on the steel pipe is a bit, makes a bend pipe and often need repeat repeatedly could accomplish, and time-consumingly in the construction takes a lot of work again and influences project progress; For the thin steel pipe of tube wall, also be damaged easily during bend pipe, produce curved flat and concave point phenomenon; Mostly above-mentioned in addition pipe bender is Cast Iron Products, and Cast Iron Products is shaky, and during use, handle and elbow junction and connecting plate rupture easily, and the connecting plate of particularly going up between supporting and supporting down ruptures the most easily, has potential safety hazard.
The utility model content
The technical problem that the utility model will solve is to overcome above-mentioned deficiency, and a kind of simple in structure, one-time formed manual pipe bender of ability is provided.
The utility model adopts following technical scheme to be achieved:
A kind of manual pipe bender; Comprise handle; The lower end vertical fixing of said handle has the circular arc support slot; The center of circle of said circular arc support slot and its outer wall homonymy, and the longitudinal section of said support slot is semicircle, said circular arc support slot is fixedly connected with a side of said handle through being fixedly connected frame; The opposite side of said handle is fixedly connected with the support hook with semicircle crotch, and the diameter of said semicircle crotch and said circular arc support slot end face is identical, the place plane parallel, and the former center of circle is positioned on latter's axis; Said support hook middle part is provided with lateral bending, and said support hook is fixedly connected with said handle through being fixedly connected frame at said lateral bending place.
Wherein, described circular arc support slot is preferably the 1/5-1/3 circular arc.
Described lateral bending is arranged on shearing force maximum between the said support hook two ends.
Described support hook is processed by reinforcing bar or seamless steel pipe.
Described handle, circular arc support slot are processed by steel pipe.
Described support hook is processed by spiral.
The utility model is compared with existing manual pipe bender; Have the following advantages: the said circular arc support slot of the utility model further is fixed on the said handle through being fixedly connected frame; Make said support slot and handle firmly connect together, active force can follow fan-shaped circular arc evenly stressed when bend pipe, causes elbow that curved flat and concave point phenomenon can not take place; But one-shot forming need not be measured repeatedly; The support hook of the utility model is provided with lateral bending, can effectively prevent the detrusion of metal tube; The utility model is drawn materials conveniently, and handle, circular arc support slot all can be processed by steel pipe, and wherein support slot can half be simmered into circular arc and makes from middle crosscut by steel pipe, makes simple and is not easy fracture; Support hook adopts spiral to process in the preferred embodiment, makes the bottom support point have anti-skidding effect, can not come off in the use and hurt sb.'s feelings; The manual pipe bender of the utility model in addition, also have cost low, simple in structure, make characteristics simple, the time and labour saving, the bend pipe group of especially making is attractive in appearance neat.
Description of drawings
Fig. 1 is the side structure sketch map of the manual pipe bender of the utility model;
Fig. 2 is the Facad structure sketch map of the manual pipe bender of the utility model;
Fig. 3 is the perspective view of the manual pipe bender of the utility model.
Wherein, 1 handle, 2 support slots, 3 support hook, 31 lateral bendings, 32 crotches, 4 are fixedly connected frame
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in Fig. 1-3, the manual pipe bender of the utility model comprises handle 1, support slot 2, support hook 3 and is fixedly connected frame 4.Wherein support slot 2 is a circular arc, preferred 1/5-1/3 circular arc, more preferably 1/4 circular arc.As shown in the figure, the longitudinal section of this circular arc support slot 2 is semicircle, and promptly support slot is the curved groove of circular arc with semicircle inner fovea part, and the center of circle of said circular arc support slot 2 and its outer wall homonymy.This support slot 2 can be processed by steel pipe, steel pipe is cut half in the middle of the end face after, the circular arc that is simmered into 1/4 circle again gets final product, and also can once cast or other modes make.Then handle 1 is vertically welded on the circular arc support slot 2 end outer walls; Preferred weld is from front end 20mm place; Wherein support slot 2 is fixing with being fixedly connected frame 4 welding with the angle neutral place that handle 1 one sides form; Support slot 2 and handle 1 are firmly linked together, thereby the active force that the operator applies when bend pipe will be evenly stressed along the circular arc of support slot 2, curved flat and concave point phenomenon can not take place.The opposite side of handle 1 is welded with an end of support hook 3; The crotch 32 of the other end bending semicircular in shape of support hook 3; The diameter of semicircle crotch 32 equals support slot 2 semi-circular recesses diameters; And crotch 32 place plane parallel are in support slot 2 semi-circular recesses proximal end faces, on the axis that is centered close to support slot 2 of crotch 32.Support hook also is provided with lateral bending 31 between 3 two ends; This lateral bending 31 is preferably placed at the suffered shearing force maximum of support hook; Lateral bending 31 lower ends of support hook 3 are fixedly connected with handle 1 through being fixedly connected frame 4, thereby overcome metal tube member suffered shearing force when bend pipe, avoid its detrusion.Wherein, The handle 1 of the utility model, support slot 2 are processed by steel pipe, the steel pipe of handle 1 preferred DN25 and DN32, and length can be decided according to operator's s own situation; Be generally 1.8m; The preferred steel pipe manufacturings that adopt DN32 of support slot 2, support hook 3 is processed by reinforcing bar or seamless steel pipe with equality strength, is fixedly connected frame 4 and can adopts band iron, pound flat steel scrap pipe etc.
In the present embodiment; Handle 1, support slot 2 adopt the DN32 steel pipe manufacturing, and support hook 3 is the spiral of 300mm, and the crotch 32 that diameter is 32mm is simmered in the lower end; And the 100mm place is provided with a lateral bending 31 above crotch, and this lateral bending 31 is fixedly connected with handle 1 as being fixedly connected frame 4 through band iron.The manual pipe bender of the utility model also can strengthen according to the size of caliber or reduce to support the size of radian and the thickness of handle, and the position of lateral bending.
During use, only need steel pipe is placed in support slot 2 and the support hook 3, operating personnel stand and firmly can realize the steel pipe bend pipe downwards in handle 1 side.Because support hook 3 has screw thread to increase the frictional force between support hook and metal pipe-wall, has good skidproof effect, comes off when avoiding the use of and hurts sb.'s feelings.
More than the description of the utility model is belonged to schematic illustration; And persons skilled in the art; According to the description of this embodiment, to structure or layout type some possibly take place all and change, only otherwise break away from the design aim of the utility model; All conspicuous changes and the similar Design with equivalent substitution all are included within the protection domain of the utility model.
