The specific embodiment
Fig. 1 is the disclosed embodiment of the utility model.The main shaft 21 terminal splines of double stirrup mold reinforcing bar bending machine cooperate with the spline housing 11 of decelerator 7, and bending hoop rotating disk 2 usefulness screws 24 are fixed on the end of main shaft 21 front ends; Two stirrup moulds 1 are fixed on the stop collar 20 by screw, between two stirrup moulds 1 and the stop collar 20 copper sheathing 23 are arranged, and the outer shroud of copper sheathing 23 has shoulder.The centre bore that bending hoop rotating disk 2 is installed two stirrup moulds 1 also has shoulder, and this shoulder matches with copper sheathing 23 outer shroud shoulders and prevents two stirrup mould 1 axial floats.The left side afterbody of two stirrup moulds 1 is embedded in the chute 29 of frame, and two stirrup moulds 1 can only move left and right can not be rotated.With screw 28 fixed guides 25, use fixedly bending hoop axle 3 of square nut 27 in the guide rail 25 on the bending hoop rotating disk 2, the pivoted housing 26 on the bending hoop axle 3 is replaceable, changes the back and is fixed by screw.The cylinder body of cylinder 10 is connected with the fixedly otic placode 6 of frame with bearing pin 9, the piston rod of cylinder 10 links together with eccentric shaft 17 by joint 13, bearing pin 14, connecting rod 15, eccentric shaft 17 is installed within the eccentric a set of cups 18, and eccentric shaft 17 lower end axles match with roller 19.
Two stirrup mould 1 front surface butterfly structures have medial launder, and both sides, the left side boss of medial launder has 15 ° gradient, and there is circular-arc boss on the both sides, right side, and the diameter of circular arc boss is 7 times of moment reinforcement diameter.
When crooked clockwise, bending hoop axle 3 initial positions are parked in the reinforcing bar top, and bending hoop rotating disk 2 turns clockwise under the drive of main shaft 21, and reinforcing bar is crooked clockwise under the effect of the bending force that bending hoop axle 3 applies.The rotation of main shaft 21 simultaneously is by servomotor 4 controls, and servomotor 4 is by angular transducer control, and up to the desired angle of bending, bending hoop rotating disk 2 returns initial position.When crooked counterclockwise, bending hoop rotating disk 2 contracts earlier under the drive of main shaft 21 backward, is driven by servomotor 4 then to turn clockwise, and around arriving the reinforcing bar below, bending hoop rotating disk 2 stretches out again, realizes commutation up to bending hoop axle 3.
Servomotor 4 drives main shafts 21 and 2 rotations of bending hoop rotating disk, and at this moment two stirrup moulds 1 can not rotate owing to be embedded in the chute 29 of frame.
On the bending hoop rotating disk 2 indentation is arranged, be used for measuring the radial position of bending hoop axle 3, increase the friction between bending hoop axle 3 and the bending hoop rotating disk 2 simultaneously.The gradient of two stirrup mould 2 afterbodys is feedings of reinforcing bar for convenience.
