Referring to accompanying drawing 1-7, basic functional principle of the present invention is: reinforcing bar 21 passes in the middle of the piston rod of hydraulic cylinder 10 forward from back folder 11, pass chuck 9 and hydraulic jack 7 front end to anchor clamps 6 again, by self-lock force clamping reinforcing bar, reinforcing bar was then loosened in motion backward when wherein anchor clamps 6 and 9 travelled forward.This moment is when pressing manual cold drawn knob, motor 20 drives the liquid pump fuel feeding and gives back folder oil cylinder 25 and hydraulic jack 7, reinforcing bar is by the front and back clamp and travel forward stretching, first section reinforcing bar after stretching is pushed into front end shearing device place through counter wheel 2, non-return folder 12, after the type that operating computer keyboard input simultaneously need be processed, processing quantity, the length of side, cold drawn length etc. have related parameter, but press the just complete operation program of button of carrying out.

In the concrete operations (is example with the stirrup), the program of operation electronic computer input processing stirrup, send instruction and make motor start-up, oil pump is started working, hydraulic oil is connected by solenoid directional control valve and is drawn the oil circuit of feeding oil cylinder 7 and 10, drive anchor clamps 6,9 alternately feedings forward, the realization of oil cylinder 7,10 alternating movements is to send corresponding instruction by computer by the signal that detects chucking position sensor 42 to control solenoid directional control valve.Feeding speed is between 0.05 meter~0.8 meter of per second, and feeding speed can increase by a cover governing system in hydraulic system controls, and also can also carry out high low velocity control by two oil pumps by the variable oil pump control of flow.Reinforcing bar travels forward under the clamping of self-locking anchor clamps 6,9, compress sensor 27 countings that drive counter wheel 2 lower ends by roller, computer is judged according to the data of sensor input, after judging the length that first segment length reaches regulation, computer sends instruction and stops feeding, drives oil cylinder 17 actions that hydraulic valve makes brake forming simultaneously, rotates through rack drives scratch diskette 14, reinforcing bar is influenced along with rotation by block 13, and scratch diskette drives angular transducer 27 rotations again simultaneously.Computer judges that according to the signal of angular transducer input after turning cylinder 22 forwarded predetermined angular to, reinforcing bar was bent moulding, and computer sends instruction resets curved cylinder.Simultaneous computer sends again to instruct to make and draws feeding oil cylinder action and alternately feeding forward, repeat the working procedure of above feeding and brake forming, after finishing five feeding brake forming work, send after one section computer just to send again forward and stop the instruction that rupturing operation is carried out in feeding.After this, because the effect of sequence valve 41 in the hydraulic system (seeing accompanying drawing 5), cutter head 15 is stretched out in vertical cut cutter oil cylinder 18 action earlier, and with bar diameter sustained height processed on the table top, revolving knife oil cylinder 1 moves and revolving knife 16 is laterally advanced bar cutting.So far, a rectangle hoop completes.

By above operation sequence as can be known, the present invention is by cold drawn (feeding) brake forming, and the order of final cutting is finished three process, is different from other machinery processing apparatus.In addition, the set oil cylinder 7 of the present invention plays two kinds of effects simultaneously, is cold drawn effect, is again feeding effect oil cylinder.When back folder oil cylinder 25 actions made rear jig 11 clamp reinforcing bar, the action of oil cylinder 7 travelled forward anchor clamps 6 clamping reinforcing bars, and reinforcing bar is again feeding by cold drawn simultaneously at this moment.After cold drawn percentage elongation reached specific length, oil cylinder 25 resetted, and after back folder 11 loosened, cold drawn effect was removed.Be failure to actuate as if back folder oil cylinder 25, when back folder 11 was in relaxation state, when oil cylinder 7 drive anchor clamps 6 travelled forward, 7 of oil cylinders played the feeding effect.

On the work top of the present invention processed reinforcing bar one side and above topped skewback 28, the effect of skewback is after reinforcing bar is bent moulding, be guided in the top of undressed reinforcing bar, thereby be hooked in the mechanisms such as counter wheel flexual center axle can avoid being pushed to the place ahead the time.

The present invention to reinforcing bar cold drawn, send to by anchor clamps 6,9 and 11 actings in conjunction of back folder and realize down.The back folder is made up of a fixed chuck and a moving chuck that is connected on folder oil cylinder 25 piston rods of back, and they can parallelly clamp reinforcing bar by back folder oil cylinder control.Wherein anchor clamps 6 are consistent with 9 structural principles but jaw quantity can be different, jaw 30 more than 2 pairs all will be arranged, when jaw is advanced by the piston rod drive at whole anchor clamps, owing on jaw and the straight line one 3 °~15 ° angle is arranged perpendicular to reinforcing bar, jaw is when travelling forward passively, can under the effect of extension spring 32, tighten reinforcing bar 21, and drag reinforcing bar and travel forward, then unclamp reinforcing bar backward.The quantity of jaw is many more, and chucking power is big more, and is more little to the damage of rebar surface, more little to the clamped reinforcing bar glacing flatness influence of loosening again after stressed.If only use a pair of jaw, make easily by distortion of the reinforcing bar after the jaw action and surface damage.Jaw connecting rod 31 is hinged with steel pin with the jaw close end more than two pairs, make a plurality of jaw interlocks on each limit, like this when swing toward front and back the end of each limit jaw, all the time point-blank, under the effect of extension spring, jaw can equidistantly be pressed to reinforcing bar equably.Jaw is when clamping reinforcing bar, and the end of jaw connecting rod and housing 29 inner edges should be gapped, and this gap is advisable at 2~6 millimeters.
