For solving above technical problem, technical scheme of the present invention is: dowel bending machine, its difference is: it comprises jack, the cylinder upper end face arranged outside of described jack has platform steel plate, described platform steel plate lower end is provided with and connects the triangular steel plate of jack cylinder body with support platform steel plate, on described platform steel plate, be provided with two pairs of mounting ears about jack symmetry, between two pairs of described mounting ears, be connected with limit stiffener, described limit stiffener can stop two pairs of mounting ears outwards to open because of stressed, between every pair of mounting ear, be flexibly connected by pin, every pair of mounting ear root is provided with the end stiffener being connected with platform steel plate for strengthening mounting ear, cylinder body one side of described jack is also provided with carrying handle.
By above technical scheme, the top cap upper surface of described jack is cambered surface, in cambered surface, is provided with U-shaped groove along circumferential direction.
By above technical scheme, the angle of described mounting ear and platform steel plate is 65 °～80 °.
Contrast prior art, beneficial features of the present invention is:
1), while laying reinforcing bar, plug pin muscle body both sides are fixed on mounting ear, then, to jack pressurization, top cap pushes up outward, makes reinforcing bar bending, can make fast and effectively reinforcing bar bending;
2), on platform steel plate, be provided with two pairs of mounting ears about jack symmetry, while laying reinforcing bar, on mounting ear, plugging pin is fixed reinforcing bar both sides, in bar bending process, do not need the hand-held dowel bending machine of workman to fix, safer, after reinforcing bar bending finishes, extract pin and can take off dowel bending machine, easy to use;
3), the top cap upper surface of jack is cambered surface, in cambered surface, is provided with U-shaped groove along circumferential direction, reinforcing bar is bent along U-shaped groove, can prevent from sliding in bar bending process, efficiency is high, safe;
4), platform steel plate lower end is provided with to be connected with between the triangular steel plate of support platform steel plate, two pairs of mounting ears and can stops two pairs of mounting ears to be provided with the end stiffener being connected with platform steel plate for strengthening mounting ear because of the stressed limit stiffener outwards opening, every pair of mounting ear root, ensure rigidity and the intensity of dowel bending machine, safe.

Detailed description of the invention
By reference to the accompanying drawings the present invention is described in further detail below by detailed description of the invention.
Please refer to Fig. 1 to Figure 10, embodiment of the present invention dowel bending machine, it comprises jack 1, the cylinder body 1-1 upper surface arranged outside of described jack 1 has platform steel plate 2, described platform steel plate 2 lower ends are provided with and connect the triangular steel plate 3 of jack cylinder body 1-1 with support platform steel plate 2, on described platform steel plate 2, be provided with two pairs of mounting ears 4 about jack 1 symmetry, between two pairs of described mounting ears 4, be connected with limit stiffener 5, described limit stiffener 5 can stop two pairs of mounting ears 4 outwards to open because of stressed, between every pair of mounting ear 4, be flexibly connected by pin 6, every pair of mounting ear 4 roots are provided with the end stiffener 7 being connected with platform steel plate 2 for strengthening mounting ear 4, cylinder body 1-1 mono-side of described jack 1 is also provided with carrying handle 8.
Concrete, the top cap 1-2 upper surface of described jack 1 is cambered surface, in cambered surface, is provided with U-shaped groove along circumferential direction.
Concrete, described mounting ear 4 is 65 °～80 ° with the angle of platform steel plate 2.
Preferably, described mounting ear 4 is 75 ° with the angle of platform steel plate 2.
Please refer to Fig. 1 to Figure 10, in the embodiment of the present invention, the effect of limit stiffener 5 is to stop the mounting ear 4 on both sides outwards to open; End stiffener 7 is in order to strengthen being connected of mounting ear 4 and platform steel plate 2, to strengthen mounting ear 4 root rigidity, because along with the bending of reinforcing bar, the outside tension force of mounting ear 4 is increasing, for the distortion of not splitting of mounting ear 4 roots, so set up end stiffener 7; The effect of triangular steel plate 3 is in order to prop up platform steel plate 2, reduces the suffered moment of flexure of platform steel plate 2, prevents that platform steel plate 2 is out of shape.
Please refer to Fig. 1 to Figure 10, in the embodiment of the present invention, jack 1 is hydraulic jack, auxiliary equipment is hydraulic oil pump, be mainly to utilize liquid to carry out work to the equal characteristic of the pressure of different directions transmission in closed container, oil pump is to conveying liquid force feed in jack cylinder, and hydraulic oil produces pressure in narrow space, now pressure increases along with increasing of hydraulic pressure oil mass, until promote piston rod 1-3 by reinforcing bar bending; When bar bending, first jack piston rod 1-3 is regained completely, by the reinforcing bar of manually carrying dowel bending machine and put anchoring, on mounting ear 4, plugging pin 6 is fixed muscle body both sides, open oil pump pressurization, jack piston rod 1-3 pushes up outward, in the time that top cap 1-2 withstands reinforcing bar, workman can unclamp dowel bending machine, reinforcing bar is folded into after specified angle, oil pump oil return, extracts pin 6, takes off dowel bending machine, greatly improve reinforcing bar bending speed, can ensure workman's personal safety, save the time, improved speed of application simultaneously.
The present invention both can carry out bending by the exposed parts of anchor bar, also can be for general bar bending, quick, safe, light solution the confined space or unfavorable construction surface anchoring Large-size rebar is carried out to a bending difficult problem.
Above content is the further description of the present invention being done in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations. For the those of ordinary skill of the technical field under the present invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
