Abstract

The utility model provides an oil hydraulic rib bender applicable to bending the rib. An oil hydraulic ejection mechanism is arranged at the middle of a V-shaped seat where the supporting points at the two ends are respectively provided with a roller; a rib is arranged across the supporting points at the two ends of the V-shaped seat and can bend the rib through an oil hydraulic ejection mechanism. Having simple structure, the utility model can not only decrease the friction between the roller and the rib and prevent jumping, but also can enhance the operation safety and reduce the output energy of the oil hydraulic ejection mechanism, thereby improving the utilization efficiency of the product.

Description

The hydraulic type bender

Technical field

The utility model relates to bender, refers to a kind of hydraulic type bender that is used to bend reinforcing bar especially, is equiped with roller on the strong point at its V-type seat two ends, and by rotatable roller on the strong point, with the frictional force between reduction and the reinforcing bar.

Background technology

If buildings in general is during with the armored concrete construction, then must bend reinforcing bar in many parts, and the bender of known bending reinforcing bar, shown in Fig. 5,6, be equiped with an oil pressure ejecting mechanism b in the middle part of a V-type seat a, and have the shape of a colluding strong point a1 at V-type seat a two ends, reinforcing bar c is bridged, by oil pressure ejecting mechanism b reinforcing bar C is bent again the colluding on the shape strong point a1 of V-type seat a two ends.

Yet, the V-type seat a two ends of known bender are to collude shape strong point a1 as the strong point of reinforcing bar, and this to collude shape strong point a1 only be a fixed structure, so this reinforcing bar c bridges and is colluding on the shape strong point a1, again by oil pressure ejecting mechanism b roof pressure in the centre position of reinforcing bar C when bending, this reinforcing bar c and collude between the shape strong point a1 to produce and slide, produce very big friction, make the bending process have some setbacks, making oil pressure ejecting mechanism b must expend more energy can bend reinforcing bar C.

Moreover, this reinforcing bar C mostly is corrugated bar, its surface has the ring line, as reinforcing bar c and collude between the shape strong point a1 and to produce when sliding, this colludes shape strong point a1 and skips to next ring point by a ring point on reinforcing bar c surface easily, when reinforcing bar C generation is beated, and then very easy causing danger, therefore very dangerous on manipulating, poor safety performance.

The inventor has above-mentioned disappearance thoughts on the bender of known bending reinforcing bar, thereby sets about design, designs a kind of hydraulic type bender finally.

Summary of the invention

Main purpose of the present utility model is: a kind of hydraulic type bender that is applicable to reinforcing bar is provided, be equiped with roller on the strong point at the V-type seat two ends of this bender, and by rotatable roller on the strong point to reduce the frictional force between itself and the reinforcing bar, to avoid producing the situation of beating, so that the security of use to be provided.

Another purpose of the present utility model is: provide a kind of and on the strong point at V-type seat two ends, be equiped with roller, and by rotatable roller on the strong point to reduce the frictional force between itself and the reinforcing bar, to reduce the output energy of oil pressure ejecting mechanism.

The realization the technical solution of the utility model is: a kind of hydraulic type bender, be equiped with an oil pressure ejecting mechanism in the middle part of a V-type seat, this reinforcing bar bridges on the strong point at V-type seat two ends, it is characterized in that: respectively be provided with a roller on the strong point at these V-type seat two ends.

The utility model is owing to be equiped with an oil pressure ejecting mechanism on the middle part of a V-type seat, a reinforcing bar bridges on the strong point at V-type seat two ends, by the oil pressure ejecting mechanism reinforcing bar is bent again; Wherein: respectively be provided with a roller on the strong point at these V-type seat two ends; According to above-mentioned structure, can reduce friction between itself and the reinforcing bar by rotatable roller on the strong point, avoiding producing the situation of beating, thereby have preferable safety in utilization, and can reduce the output energy of oil pressure ejecting mechanism, and then improve the service efficiency of product.

Specific embodiment

Referring to Fig. 1-3, a kind of hydraulic type bender is equiped with the reinforcing bar 3 that an oil pressure ejecting mechanism 2, bends in advance and bridges on the strong point 11 at V-type seat 1 two ends in the middle part of one V-type seat 1, again by oil pressure ejecting mechanism 2 with reinforcing bar 3 bendings; Wherein respectively be provided with a roller 11a on the strong point 11 at these V-type seat 1 two ends, and reduce frictional force between itself and the reinforcing bar 3 by rotatable roller 11a on the strong point 11, as shown in Figure 4, above-mentioned reinforcing bar 3 lucky some be fastened in the notch of roller 11a, take place with the situation of avoiding job-hoping.

According to above-mentioned structure, at first need reinforcing bar 3 is bridged on the strong point 11 at V-type seat 1 two ends, as shown in Figure 3, this strong point 11 has a roller 11a, when the centre position that the oil compression rod of oil pressure ejecting mechanism 2 leans against reinforcing bar 3 outwards ejects, when this reinforcing bar 3 and the strong point 11 produce and slide, promptly by rotatable roller 11a with minimizing friction therebetween, so be minimized the output energy of oil pressure ejecting mechanism 2.

Moreover when bending owing to this reinforcing bar 3, this reinforcing bar 3 is because of bridging on roller 11a, and this roller 11a is rolled, therefore can reduce friction therebetween in a large number, be avoided reinforcing bar 3 in the bending process, to produce the situation of beating and take place, so have preferable safety in utilization with the strong point 11.

In sum, the disclosed structure of the utility model does not in the past have, and can reach above-mentioned effect really, because of possessing the important document of novel patent, so file an application in accordance with the law.

Claims

1, a kind of hydraulic type bender is equiped with an oil pressure ejecting mechanism in the middle part of one V-type seat, and a reinforcing bar bridges on the strong point at V-type seat two ends, it is characterized in that: respectively be provided with a roller on the strong point at these V-type seat two ends.
