The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail:
Present embodiment discloses a kind of pipe fitting pipe bender, is used for bending stainless steel tube, seamless steel pipe and cable tube in cold stewing mode, is made of workbench 1, fixed wheel 6, driving wheel 2, turning handle 4 and stop block 7.As shown in Figure 1, fixed wheel 6 and driving wheel 2 are connected in turning handle 4 jointly by first rotating shaft 5 and second rotating shaft 3 respectively.Fixed wheel 6 is fixed on the workbench 1, so be referred to as fixed wheel 6; Driving wheel 2 is driven by turning handle 4, rotates around fixed wheel 6, so be referred to as driving wheel 2.Also be provided with stop block 7 on the workbench 1, be installed near the position the fixed wheel 6, be used for fixing an end of pipe fitting.The height of stop block 7 generally will with the upper surface flush of fixed wheel 6.
During operation, pipe fitting one end is stuck on the stop block 7, remainder penetrates between fixed wheel 6 and the driving wheel 2, promotes turning handle 4, and driving wheel 2 is rotated around fixed wheel 6, and pipe fitting also bends thereupon and forms.Like this, can be more laborsaving during operation, accelerate operating efficiency.
Workbench 1 comprises a horizontal plane at least, can be connected on the position that the work-yard is fit to height by the one face down bonding, also can supporting leg be set in the bottom and be placed on the scene.The shape of workbench 1 can be square, rectangle or add semicircular similar orbit-shaped in the rectangle one or both ends.Its size is definite as the case may be, but will satisfy the requirement greater than driving wheel 2 radiuses of gyration at least, in order to avoid driving wheel 2 comes off, minimum is the L=400mm square.
Be installed with fixed wheel 6 on the workbench 1, fixed wheel 6 is horizontally set on the workbench 1, and wheel face is parallel with workbench 1 surface, is transfixion with respect to workbench 1.As shown in Figure 3 and Figure 4, on the opposite position of workbench 1 and fixed wheel 6, offer three internal thread holes 10 that have M14 internal thread (internal diameter of fine and smooth line can in 12～16 scopes) respectively, internal thread hole 10 on the workbench 1 should be a through hole, internal thread hole 10 on the fixed wheel 6 can not be a through hole, pass the internal thread hole 10 on workbench 1 and the fixed wheel 6 successively and tighten by bolt 8, fixed wheel 6 levels are anchored on the workbench 1, and at this moment, fixed wheel 6 wheel faces contact with workbench 1 surface.Bolt 8 must be selected high-strength bolt for use, could guarantee fixed wheel 6 firm being fixed on the workbench 1 in the stewing system process like this.
Fixed wheel 6 axle center are provided with first axis hole 9, are used to install first rotating shaft 5 of turning handle 4 ends.First axis hole 9 promptly is the center of circle of pipe fitting being simmered bending radius in the system process.
The same horizontal plane of fixed wheel 6 is provided with driving wheel 2, driving wheel 2 axle center be provided with and first axis hole 5 with second axis holes 11 in footpath, second rotating shaft, 3, the second rotating shafts 3 that are used to install turning handle 4 middle parts are also identical with first rotating shaft, 5 specifications.
As shown in Figure 6, turning handle 4 is made of connecting portion 41 and hand grip portion 42 one, and hand grip portion 42 can suitably dwindle the interface with respect to connecting portion 41, so that hold with a firm grip and exert oneself.The diameter that connecting portion 41 is welded with first rotating shaft 5 and second rotating shaft, 3, the first rotating shafts 5 is slightly less than 5, the second rotating shafts 3 of first axis hole in like manner.But the gap between rotating shaft and the wheel hole is unsuitable excessive again, and usually, the spacing between first rotating shaft 5 and second rotating shaft 3 should be greater than the radius sum 5～10mm of fixed wheel 6 and driving wheel 2.First rotating shaft 5 and second rotating shaft 3 can select for use round steel to be welded in the relevant position of connecting portion 41 after polishing slightly, if reinforcement intensity, also can the steel plate positive and negative of turning handle 4 bore saturating after, adopt the positive and negative welding.
As shown in Figure 5, the wheel rim of fixed wheel 6 and driving wheel 2 outside all is provided with same deep-slotted chip breaker, is used for the pipe fitting inlay card therein.Theoretically, deep-slotted chip breaker should be a semicircle, but considers the strength problem at wheel edge, and deep-slotted chip breaker selects to be slightly smaller than the radian of semicircle, and the thickness of 1mm is abdicated on both sides respectively at least, shown in the dotted line, like this, can satisfy the simmering and bending requirement among the figure, can gain in strength again.
In order to achieve the above object, the thickness that requires fixed wheel 6 and driving wheel 2 is greater than the external diameter of simmering tubulation spare, and the assurance certain intensity.In general, if the diameter of simmering tubulation spare between 14～18mm, then selects for use the steel plate thickness of making fixed wheel 6 and driving wheel 2 just need be between 20～22mm.Make fixed wheel 6 and driving wheel 2 steel plate thickness and preferably equate, at least also be greater than pipe fitting diameter 2mm simultaneously.
In addition, generally, the requirement of simmering tubulation spare is that the pipe fitting bending radius is not less than more than six times of its diameter, can draw with above-mentioned relation, and the diameter of fixed wheel 6 is exactly the bending radius of pipe fitting, therefore can determine fixed wheel 6 external diameters by accurate Calculation.Driving wheel 2 external diameters are not done concrete restriction, generally are made as half of fixed wheel 6 external diameters, easy operating.
Change slightly for the foregoing description, form another embodiment, as shown in Figure 7, at first fixed wheel 6 lower surfaces are welded on the workbench 1 by leg 12, like this, between fixed wheel 6 and the workbench 1 certain distance are arranged; Secondly, the connecting portion of turning handle 4 was made as two parts up and down in 41 minutes, driving wheel 2 is clamped in wherein.Particularly, the connecting portion 41 of turning handle 4 front ends is made of last connecting portion 411 and following connecting portion 412, and last connecting portion 411 extends to fixed wheel 6 from hand grip portion 42, and following connecting portion 412 extends to driving wheel 2 from hand grip portion 42.
Although in conjunction with the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment only is schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away under the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, these all belong within the protection domain of the present utility model.
