[0022] like Figures 1 to 4As shown, the present invention provides an FRP-steel composite reinforcement bending processing equipment, comprising: a workbench 1, a through hole 101 axially passing through the workbench 1 is provided on the workbench 1, a fixing frame 3 for placing the first end of the FRP reinforcement 2 is fixedly installed on the workbench 1, one end of the fixing frame 3 extends into the through hole 101 and is provided with an inflection point 301 for bending the FRP reinforcement, a first support plate 4 for supporting the first end of the FRP reinforcement 2 is slidably installed on the fixing frame 3, a rotating frame 5 for placing the second end of the FRP reinforcement is rotatably installed on the workbench 1, the rotating frame 5 can rotate circumferentially along the through hole 101, a second slot 501 for placing the FRP reinforcement is provided on the rotating frame 5, an arc groove 502 is provided on the rotating frame 5 on one side of the FRP reinforcement 2 along the bending direction, a second support plate 503 capable of sliding along the arc groove 502 is provided in the arc groove 502, and the second support plate A first elastic member 504 is fixedly connected between 503 and the inner wall of the arc groove 502, and a first tooth shape 505 is provided on the outer diameter side of the second support plate 503, and a gear 506 meshing with the first tooth shape 505 is rotatably installed in the arc groove 502, and the gear 506 extends out of the arc groove 502. A discharge position 102 is provided on the workbench 1, and a second tooth shape 507 meshing with the side of the gear 506 extending out of the arc groove 502 is provided on the discharge position 102. The rotating frame 5 rotates circumferentially along the through hole 101 to the discharge position 102, so that the gear 506 can roll along the second tooth shape 507 so that the second support plate 503 provided with the first tooth shape 505 slides along the arc groove 502 to disengage from the second slot 501; the first support plate 4 and the second support plate 503 are synchronously moved by the transmission mechanism to make the first support plate 4 disengage from the FRP rib 2, so that the FRP rib 2 falls from the discharge position 102.

[0023] In this solution, in the initial state, the two ends of the FRP rib 2 are placed on the first support plate 4 and the second support plate 503 respectively. When bending, the rotating frame 5 is rotated along the circumferential direction of the through hole 101 to move the rotating frame 5 toward the discharge position 102, wherein the end of the fixed frame 3 extending into the through hole 101 serves as the inflection point 301, thereby bending the FRP rib 2. Before the rotating frame 5 moves to the discharge position 102, the second support plate 503 and the gear 506 remain stable. When the rotating frame moves to the discharge position 102, the gear 506 and the second gear 506 are in contact. The second tooth profile 507 is engaged, so that the gear 506 rolls along the second tooth profile 507, thereby driving the second support plate 503 to slide along the arc groove 502, so that the second support plate 503 is separated from the FRP rib 2. The second support plate 503 causes the first support plate 4 to move synchronously through the transmission mechanism, so that the first support plate 4 is separated from the FRP rib 2, and the FRP rib 2 falls from the unloading position 102. Then, the rotating frame 5 is rotated back to its original position, and the two ends of the new FRP rib 2 are placed on the first support plate 4 and the second support plate 503 respectively, and the above steps are repeated to bend.

[0024] Through the design of the above structure, this solution can automatically open the support plate used to support the FRP bar after the FRP bar is bent to a preset angle, allowing the FRP bar to fall from the unloading position, reducing manual picking and placing and improving the bending efficiency of the FRP bar.

[0025] In one embodiment of the present invention, the transmission mechanism includes a gear ring 6 rotatably mounted on the workbench 1, the gear ring 6 is linked to the first support plate 4, the inner ring of the gear ring 6 is provided with a tooth shape, the unloading position 102 is provided with a fixed plate 601 fixed to the workbench 1, the fixed plate 601 is provided with a slide plate 602 that can slide along the circumferential direction of the through hole 101, a second elastic member 603 is fixedly connected between the slide plate 602 and the fixed plate 601, and an arc-shaped gear plate 604 that can slide radially along the through hole 101 is slidably mounted on the slide plate 602 The arc-shaped tooth plate 604 is provided with a tooth shape that meshes with the gear ring 6, and a third elastic member 605 is fixedly connected between the arc-shaped tooth plate 604 and the slide plate 602. The inner ring of the arc-shaped tooth plate 604 is provided with a first inclined edge 606, and a push plate 607 is fixedly connected to the second support plate 503. One end of the push plate 607 is provided with a second inclined edge 608 that cooperates with the first inclined edge 606. Moving the push plate 607 can cause the second inclined edge 608 to squeeze the first inclined edge 606 to make the arc-shaped tooth plate 604 move radially along the through hole 101 to mesh with the gear ring 6.

[0026] In this solution, before the rotating frame 5 moves to the unloading position 102, the arcuate tooth plate 604 is disengaged from the gear ring 6. When the rotating frame 5 moves to the unloading position 102, the gear 506 drives the second support plate 503 to move, thereby driving the push plate 607 to move, so as to squeeze the arcuate tooth plate 604 so that the arcuate tooth plate 604 engages with the gear ring 6, so that the push plate 607 continues to move, driving the gear ring 6 to rotate, thereby causing the first support plate 4 to disengage from the FRP rib 2; so as to increase the falling rate of the FRP rib 2.

[0027] In one embodiment of the present invention, a first slot 302 for placing the FRP rib 2 is provided on the fixing frame 3, the first support plate 4 is provided in the first slot 302 to support the FRP rib 2, the first support plate 4 is fixedly connected to the gear ring 6, and rotating the gear ring 6 can make the first support plate 4 be located in the first slot 302 or detached from the first slot 302.

[0028] In one embodiment of the present invention, an annular frame 7 rotatably connected to the workbench 1 is provided in the through hole 101, the fixed plate 601 is fixedly connected to the annular frame 7, an annular groove 701 is provided on the annular frame 7, and the rotating frame 5 is slidably installed in the annular groove 701.

[0029] In this solution, the rotation of the rotating frame 5 and the annular frame 7 do not interfere with each other. Before bending the FRP rib 2, the annular frame 7 is rotated to rotate the fixed plate 601 to a preset position, and then the annular frame 7 and the workbench 1 are fixed by bolts to adapt to the bending angle of the FRP rib 2; then the rotating frame 5 is rotated to bend the FRP rib 2.

[0030] In one embodiment of the present invention, a limiting sliding groove 609 is provided on the fixed plate 601 and the rotating frame 5 , and the push plate 607 is slidably provided in the limiting sliding groove 609 .

[0031] In one embodiment of the present invention, a baffle 610 is fixedly provided on the side of the fixing plate 601 away from the FRP ribs. When the rotating frame 5 abuts against the baffle 610 , the second supporting plate 503 is separated from the second slot 501 .

[0032] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
