It is more highly preferred to, bending mandrel 133 is arranged concentrically by the present embodiment with bending main shaft 131, situation about so arranging relative to non-concentric, it is arranged concentrically the arm of force enabled between bending main shaft 131 and bending mandrel 133 minimum, and then the revolving force that bending mandrel 133 obtains can be bigger, contribute to better realizing the bending of reinforcing bar 6.
In the present embodiment, guide pillar 14 is set to two, and inside the U-shape structure being arranged on frame 11 of its level and symmetry, bent support 12 is not provided with one end of bending apparatus 13 and is set on guide pillar 14, and slides along guide pillar 14.Preferably, frame 11 is provided with cylinder 15 along guide pillar 14 length direction, the outfan of this cylinder 15 is connected to bent support 12 and is not provided with one end of bending apparatus 13, that is, stretching by cylinder 15, bent support 12 can be driven to slide along guide pillar 14, and then drive bending apparatus 13 thereon to slide.
With reference to Fig. 4-7, this three-dimensional bending mechanism 1 above-mentioned of the present embodiment is arranged at the side (being specially the right side shown in Fig. 4) of the plain bending mechanism 2 of plain bending equipment, it is by being used in combination with plain bending equipment, the three-dimensional bending of reinforcing bar 6 can be realized, automatically produce the three-dimensional stirrup needed in architectural engineering.
In the present embodiment, above-mentioned plain bending equipment includes plain bending mechanism 2, haulage gear 3, straightening mechanism 4 and cutting mechanism 5, wherein plain bending mechanism 2 is positioned at cutting mechanism 5 side, after reinforcing bar 6 sequentially passes through haulage gear 3, straightening mechanism 4 and cutting mechanism 5, it is delivered to plain bending mechanism 2 to be curved, carry out three-dimensional bending being delivered to three-dimensional bending mechanism 1 subsequently, to form 3 D stereo reinforcing bar.
Concrete, as shown in Figure 9, plain bending mechanism 2 includes plain bending and supports 21, the plain bending that is located in that is scalable and that rotate supports the plain bending main shaft 22 on 21, it is fixed in second connecting plate 23 of plain bending main shaft 22 one end, be installed in the plain bending axle 24 on the second connecting plate 23, and be arranged on the second connecting plate 23 and with the plane bend bent axle 25 of plain bending axle 24 eccentric setting.Plain bending mechanism 2 and the plain bending mechanism 2 that differs only in of three-dimensional bending mechanism 1 in the present embodiment are directly anchored on the support body of plain bending equipment, it cannot slide, all the other structures are essentially identical with the structure of three-dimensional bending mechanism 1, its bending principle is consistent with the bending principle of three-dimensional bending mechanism 1, does not repeat them here.
In the present embodiment, when the bending apparatus 13 of three-dimensional bending mechanism 1 is curved reinforcing bar, it is formed with the first plane of bending (not shown), the second plane of bending (not shown) it is formed with during plain bending mechanism 2 moment reinforcement, above-mentioned first plane of bending and the angled setting of the second plane of bending, and then ensure that the reinforcing bar after final bending is stereochemical structure.Preferably, first plane of bending of the present embodiment and the second plane of bending are arranged at an angle of 90.
Below the three-dimensional bending mechanism of the present invention is illustrated with the use of the three-dimensional bending process completing reinforcing bar 6 with plain bending equipment:
First, as shown in Figure 4, reinforcing bar 6 is delivered to place of plain bending mechanism 2 under the drive of haulage gear 3 and straightening mechanism 4, the plain bending main shaft 22 of plain bending mechanism 2 rotates and drives plain bending axle 24 and plane bend bent axle 25 to rotate, by reinforcing bar 6 bending on the second plane of bending formed, Fig. 4 show and has bent two angles on the second plane of bending.Now three-dimensional bending mechanism 1 does not have action, and haulage gear 3 continues to drive reinforcing bar 6 to move to three-dimensional bending mechanism 1.
Subsequently, as shown in Figure 5, haulage gear 3 drives reinforcing bar 6 to move to place of three-dimensional bending mechanism 1, three-dimensional bending mechanism 1 drives bending apparatus 13 to move above reinforcing bar 6 by cylinder 15, bending main shaft 131 moves down under the drive of driving mechanism subsequently, and make reinforcing bar 6 be placed between bending mandrel 133 and bending axis 134, now three-dimensional bending mechanism 1 prepares to proceed by the bending of reinforcing bar 6.
As shown in Figure 6, the bending main shaft 131 of three-dimensional bending mechanism 1 turns an angle under the drive of driving mechanism, and make bending mandrel 133 and bending axis 134 also concomitant rotation certain angle, reinforcing bar 6 is curved by bending axis 134 on the first plane of bending formed, due to the first plane of bending and the angled setting of the second plane of bending of the present embodiment three-dimensional bending mechanism 1 and plain bending mechanism 2, therefore the reinforcing bar 6 after three-dimensional bending mechanism 1 bending is rendered as 3 D stereo state.
After three-dimensional bending mechanism 1 moment reinforcement 6 completes, as shown in Figure 7, its bending main shaft 131 retracts (now bending main shaft 131 stops operating) under the drive of driving mechanism, reinforcing bar 6 under the drive of haulage gear 3 in the opposite direction (left side shown in Fig. 7) move to required length, now plain bending mechanism 2 can continue, on the second plane of bending, reinforcing bar 6 is curved action, Fig. 7 midplane bending mechanism 2 is not curved again, now completed the shearing to reinforcing bar 6 by cutting mechanism 5, produce finished product solid stirrup as shown in Figure 8.
It should be noted that when carrying out plain bending action and working without three-dimensional bending mechanism 1, bent support 12 can be retracted under the drive of cylinder 15, and then ensure that plain bending will not be interfered by bending apparatus 13.Three-dimensional bending mechanism 1 and plane bending mechanism 2 are used in conjunction with each other, it is possible to by the change of differently curved angle, and reinforcing bar 6 is bent the various 3D shapes of generation.
Obviously, the above embodiment of the present invention is only used to the clear example of the present invention that illustrates, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here without also cannot all of embodiment be given exhaustive.All any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within the protection domain of the claims in the present invention.
