[0022] like Figures 1 to 4As shown, the present invention provides an FRP-steel composite rib bending processing equipment, comprising: a workbench 1, the workbench 1 is provided with a through hole 101 axially penetrating the workbench 1, a fixing frame 3 for placing the first end of the FRP rib 2 is fixedly installed on the workbench 1, one end of the fixing frame 3 extends to the through hole 101 and is provided with an inflection point 301 for bending the FRP rib, a first support plate 4 for supporting the first end of the FRP rib 2 is slidably installed on the fixing frame 3, a rotating frame 5 for placing the second end of the FRP rib 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 rib is provided on the rotating frame 5, an arc groove 502 is provided on the rotating frame 5 on one side of the FRP rib 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, a first tooth shape 505 is provided on the outer diameter side of the second support plate 503, a gear 506 meshing with the first tooth shape 505 is rotatably installed in the arc groove 502, the gear 506 extends out of the arc groove 502, a material discharge position 102 is provided on the workbench 1, a second tooth shape 507 meshing with the side of the gear 506 extending out of the arc groove 502 is provided on the material discharge position 102, the rotating frame 5 rotates circumferentially along the through hole 101 to the material discharge position 102, and the gear 506 can roll along the second tooth shape 507 to make the second support plate 503 provided with the first tooth shape 505 slide 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 through a transmission mechanism to make the first support plate 4 disengage from the FRP rib 2, so that the FRP rib 2 falls from the material 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 direction close to the material discharge position 102, wherein the end of the fixed frame 3 extending into the through hole 101 is used as the inflection point 301, so that the FRP rib 2 is bent. Before the rotating frame 5 moves to the material discharge position 102, the second support plate 503 and the gear 506 remain stable. When the rotating frame moves to the material discharge position 102, the gear 506 and the second gear 506 are in contact with each other. The second tooth shape 507 is meshed, so that the gear 506 rolls along the second tooth shape 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, and 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, so that the FRP rib 2 falls from the unloading position 102, and then the rotating frame 5 is rotated back to its original position, and then 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, so that the FRP bar falls 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 with 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 capable of sliding 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 capable of sliding 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 meshing with the gear ring 6, 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, a push plate 607 is fixedly connected to the second support plate 503, and one end of the push plate 607 is provided with a second inclined edge 608 matching the first inclined edge 606, and moving the push plate 607 can make the second inclined edge 608 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 is engaged 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, the fixing frame 3 is provided with a first slot 302 for placing the FRP rib 2, the first support plate 4 is arranged 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.

[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.
