In the utility model, the alignment pin 801 of bending mechanism also can adopt cylinder 21 to drive, and as shown in Figure 4, does not pass through actuated by cams.Cam mechanism can adopt other conventionally form, and as shown in Figure 9, employing arranges fork 22 and coordinates with cam 5 on hollow pipe 10; As shown in figure 10, fork 22 being set on hollow pipe 10 coordinates with cam 5 etc. by establishing the connecting rod 23 of roller 24.

Operation principle:

Referring to Fig. 1, Fig. 2, reinforcing bar 13 enters into each bending unit a automatically, b, c, after bending mechanism in d, between the pin bent 802 and alignment pin 801 of bending mechanism, motor 4 drives the cam 5 in each cam mechanism to rotate by driving shaft 2, protuberance 502 on cam 5 and the arc protuberance 501 of side coordinate with tooth bar 10 and connecting rod 6 respectively, drive their actions, by tooth bar 10 and connecting rod 6, drive respectively hollow pipe 15 rotations and alignment pin 801 in bending mechanism flexible, when hollow pipe 15 rotates, pin bent 802 is by reinforcing bar 13 bending angles (referring to Fig. 5).Because the angle of installing on driving shaft 2 from each bending unit a, b, c, cam 5 that d is corresponding is different, bending mechanism bending reinforcing steel bar in each bending unit a, b, c, d is to carry out according to the order of sequence opportunity according to the rotation of bending mechanism, the bending mechanism of the first step in bending unit a, d bends, as shown in Figure 7; The bending mechanism of second step in bending unit b, c bends, as shown in Figure 8.After completing first step bending, in bending unit a, d, the alignment pin 801 of bending mechanism coordinates with the arc protuberance 501 of cam 5 in retraction hollow pipe 15 (referring to Fig. 6) by connecting rod 6, so that reinforcing bar 13 is not stopped when second step bends, after reinforcing bar 13 second step bendings, the alignment pin 801 of bending mechanism return (referring to Fig. 2) under the effect of return spring 20 in bending unit a, d.

The rotational angle of bending mechanism determines the bending angle of reinforcing bar 13, the rotational angle of bending mechanism can be by selecting the cam of different cams hub diameter far away, the protuberance 502 that is about to cam 5 arranges different radial heights and realizes, the height of the protuberance 502 of cam 5 can make tooth bar 10 have different strokes, and then the rotational angle of decision hollow pipe 15, the rotational angle that certainly also can realize by the gear 16 of different-diameter is set on hollow pipe 15 each bending mechanism meets the angle of the each needs bending of reinforcing bar 13.

The length of reinforcing bar 13 bendings can be determined by the distance between mobile each bending unit a, b, c, d.

The number that the number of bending unit need to bend according to reinforcing bar is determined, as the reinforcing bar of two bendings needs two bending units (referring to Figure 11), the reinforcing bar of four bendings needs four bending units (referring to Figure 12), the reinforcing bar of five bendings needs five bending units (referring to Figure 13), and the reinforcing bar of six bendings needs six bending units (referring to Figure 14).

The orientation determination that the direction of reinforcing bar bending drives bending mechanism to rotate according to cam mechanism, can process the reinforcing bar as shown in Figure 11,13,14 as the bending mechanism that adopts different directions to rotate, and the bending mechanism that adopts equidirectional to rotate can be processed the reinforcing bar shown in Figure 12.
