The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail, but not as to restriction of the present utility model.
Embodiment one
As shown in Figure 1 to Figure 3, the angle-bender of an embodiment of the present utility model comprises:
Be positioned at the stand 11 on the pedestal 1, stand 11 is located between described preceding support roller 21 and the back support roller 22, and the front and back end of stand 11 (from the angle of reinforcing bar turnover) is equipped with the opening that passes through for reinforcing bar;
The driving mechanism 4 that support roller 21 and back support roller 22 rotate before driving.
During use, the horizontal rocking bar 301 of hand control is transmitted to nut screw mechanism 3 by horizontal rocking bar 301 with driving force (moment of torsion), and this nut screw mechanism 3 turns to down-pressure roller 23 with torque axis and acts on the normal pressure for the treatment of crooked reinforcing bar top.According to the bending curvature requirement of reinforcing bar, control the speed that presses down of down-pressure roller 23 and always press down height.Owing to have normal pressure between reinforcing bar and preceding support roller 21 and the back support roller 22, under the drive of driving mechanism 4, produce frictional force between the preceding support roller 21 that rotates and/or back support roller 22 and the reinforcing bar, the drive reinforcing bar advances, advancing reinforcing bar and down-pressure roller 23 contacted positions are bent downwardly, along with advancing of reinforcing bar, realized the continuous bend reinforcing bar.If wish to change the curvature of bar bending, as long as change pressing down height and pressing down speed of down-pressure roller 23.Concrete pressing down highly can be determined by experiment according to construction requirement with the speed of pressing down.When reinforcing bar moves horizontally, keep pressing down of down-pressure roller 23 highly constant, but can be processed into the reinforcing bar of the identical continuous bend of degree of crook.If wish to change the degree of crook of reinforcing bar, can appropriate change down-pressure roller 23 press down height.
About the setting of support roller, embodiment that can be as shown in Figure 1 is the same, and two support rollers only are set, and also more support roller can be set.A rotation before driving mechanism 4 can be set to only drive in support roller 21 and the back support roller 22 also can be set to drive their synchronous rotations; Be provided with under the situation of more support roller, driving mechanism 4 can be set to only drive a support roller and rotate, and also can drive their synchronous rotations.Driving mechanism 4 can adopt motor-driven, also can adopt hydraulic motor or air motor to drive.
As shown in Figure 1, in the present embodiment, the fixedly connected installing rack 33 that down-pressure roller 23 is installed that is useful in the lower end of leading screw 31, the rotating shaft of down-pressure roller 23 is installed on the installing rack 33 by bearing or axle sleeve.Particularly, installing rack 33 can be set to the front-back opening, and the also rectangular shape of opening of bottom surface, is convenient to reinforcing bar and passes through after down-pressure roller 23 is installed.
As Fig. 3, the side 112 of stand 11 is provided with vertical stopper slot 115, and installing rack 33 is provided with the slide block 63 that cooperates with stopper slot 115.Slide block 63 is positioned at stopper slot 115, the direction non-migration the when cooperation of slide block 63 and vertical stopper slot 115 can guarantee that down-pressure roller 23 presses down.In order further to control the height that presses down of down-pressure roller 23, the side 112 of stand 11 is provided with along the graduation mark (not shown) at the edge of stopper slot 115, has guaranteed the bending curvature of each point.
Continuation illustrates the angle-bender of this enforcement in conjunction with Fig. 1 and Fig. 2, and particularly, driving mechanism 4 comprises motor 40, reductor 43, first driving chain 42 and second driving chain 44.Motor 40 rotates by the runner 41 on the power shaft of belt 46 driving reductors 43.Reductor 43 drives first rotating shaft 61 that preceding support roller 21 is installed by first driving chain 42 and rotates; Reductor 43 drives second rotating shaft 62 that back support roller 22 is installed by second driving chain 44 and rotates.And, for support roller before guaranteeing 21 and back support roller 22 rotate synchronously, the output shaft of reductor 43 is provided with two identical driving gears, is respectively equipped with the number of teeth identical preceding driven gear and the back driven gear that are driven by described driving gear respectively in the rotating shaft of preceding support roller 21 and back support roller 22.Adopt motor 40 to give reductor 43 as power source with transmission of power, reductor 43 can reduce velocity of rotation and bigger moment of torsion is provided, and advances thereby make preceding support roller 21 and back support roller 22 drive reinforcing bar.On another direction, because horizontal rocking bar 301 plays the effect of lever, only need less power just can obtain bigger moment, the leading screw 31 of drive nut screw mechanism 3 rotates and the lifting of drive down-pressure roller 23, makes this mechanism more laborsaving.Nut screw mechanism 3 can realize auto-lock function in addition, and down-pressure roller 23 can not rise automatically, is easy to guarantee the requirement of reinforcing bar curvature.
As Fig. 2-shown in Figure 4, the centre of pedestal 1 is connected with vertical dividing plate 15, and driving mechanism 4 is positioned at a side of dividing plate 16, and stand 11, support roller 21, back support roller 22 and nut screw mechanism 3 are positioned at the opposite side of dividing plate 15.Dividing plate 15 separates driving mechanism 4 and miscellaneous part, avoids reinforcing bar to add the operation that has influence on associated components man-hour.In addition, as shown in Figure 2, the shift knob 51 of all right fixed electrical machinery 40 in the upper end of dividing plate 15.The axle that dividing plate 15 is provided with for preceding support roller 21 and back support roller 22 passes and hard-wired hole.In addition, dividing plate 15 can also use forms such as guardrail, as long as avoid reinforcing bar to add man-hour to the influence of driving mechanism.
Embodiment two
Embodiment two with the difference of embodiment one is, mechanism makes ball screw framework into nut screw, can reduce the active force of the horizontal rocking bar of artificial rotation, and ball screw framework is operated more laborsaving convenience compared with nut screw mechanism.As long as down-pressure roller 23 needs had the requirement of bigger axial normal pressure when less power just can satisfy bar bending.
Among above-described embodiment one and the embodiment two, adopt nut screw mechanism and ball screw framework as elevating mechanism, drive the down-pressure roller lifting, make its bending thereby compress reinforcing bar from the top of reinforcing bar, reach the purpose of bar bending.In addition, adopt other forms of elevating mechanism to drive the down-pressure roller lifting and also can realize the purpose of this utility model.
Certainly; the above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
