Qu Danyuan is constituted, and bar bending unit includes:Bending unit support body;Power-driven mechanism, power-driven mechanism includes:Motor;
Decelerator, the motor drives the retarder operation, and drive sprocket, the drive sprocket is arranged on the output of the decelerator
End;Driven sprocket, the driven sprocket is connected with the drive sprocket by chain;Bending mechanism, for being by bar bending
Predetermined angular;Reinforcing bar clamping device, for steel bar clamping to be prevented into reinforcing bar is shifted in bar bending;Angle of bend is adjusted
Mechanism, the angle of bend adjustment mechanism is used to set the predetermined angular, and controlled motor is stopped when bar bending is predetermined angular
Only run, decelerator and the sprocket wheel of the device angle-bender are directly connected to and carry out bending transmission, reduce transmission mechanism zero
Part, reduces main screw lift, with simple in construction, and assembly precision is low, the advantage of difficulty of processing is reduced, however, said apparatus
Must be by electric power as power source, once to arrive more complicated area, such as electric power is difficult to the area entered, just can not make
With in addition, the device is required for consuming substantial amounts of electric power per task, comparing waste.
China patent No. CN201610127070.2 discloses a kind of setting of angle-bender unit, and it includes many steel
Muscle bending machine, at least one is the moveable angle-bender of surrounding;The structure of the moveable angle-bender of described surrounding
It is such:It includes angle-bender body, and angle-bender body has frame, is the biography that motor drives inside frame
Motivation structure, is bending disk on frame, transmission mechanism is by rotating shaft connecting bending koji tray, and bending on disk has bool, bool
Including moving bool and determining bool, determine bool and be arranged in the middle of bending disk, move bool around bending disk, it is curved in reinforcing bar
Also having below bent machine body below a pallet, angle-bender body has universal wheel and on pallet, curved in reinforcing bar
There are spring connecting trays around bent machine body;The many angle-benders arrangement is on the ground.Such angle-bender
Being arranged on when bending some reinforcing bars for unit has the advantages that production efficiency height, labor intensity are small.
Above two device, it is necessary to by electric power as power source, once to arrive more complicated area, such as electric power is difficult
It with the area of entrance, just can not use, in addition, the device is required for consuming substantial amounts of electric power per task, compare waste.

Carry out spacing bending.
Specifically used mode:In present invention work, reinforcing bar is placed between two groups of limited blocks 19, and causes reinforcing bar
Limited block 19 is stretched out in one end, now, repeatedly presses moulded rod 8, in the presence of lever principle, piston 6 is moved up and down repeatedly, in sky
In the presence of atmospheric pressure, the hydraulic oil inside hydraulic pressure chamber 2 is inhaled into the inside of piston chamber 5, due to depositing for the first check valve 4
, when piston 6 is moved down, hydraulic oil will not enter hydraulic pressure chamber 2 in, enter on the contrary in the first pipeline 11, in piston 6
, can be more into the hydraulic oil in the first pipeline 11 under constantly promoting, and due to the presence of the second check valve 12, these hydraulic oil
Will not reflux to piston chamber 5, and then flow into circulating line 16, powerful hydraulic oil extruding baffle plate 21 so that baffle plate 21 occurs
Displacement, and the continuous movement of circular rod 17, when gag lever post 18 is contradicted in reinforcing bar, due to constantly exerting a force, in the He of gag lever post 18
In the presence of limited block 19, reinforcing bar bends, when bending to proper angle, stops the pressing body of rod 8, reinforcing bar is taken out, lead to
Cross opening control valve 14 so that the hydraulic oil in the first pipeline 11 and circulating line 16 is back to by second pipe 13
In hydraulic pressure chamber 2, you can.
