[0038] This utility model provides a novel rebar bending machine device through improvements. The technical solution of this utility model is as follows:

[0039] like Figure 1-11 As shown, a novel rebar bending machine device includes a workbench 1, a central pin 101 fixedly installed at the top center of the workbench 1, and an installation plate 102 fixedly installed on the inner side of the workbench 1, which provides an auxiliary function for the subsequent operation of the device. It also includes a bending component 2, a fixing component 4 and a positioning component 5.

[0040] Limiting plate 3 is set on one side of the top of workbench 1. A fixing block 301 is fixedly installed on the top of workbench 1. The fixing block 301 is set on one side of limiting plate 3, so that the reinforcing bar runs in a predetermined position.

[0041] The bending component 2 includes a first U-shaped frame 201 fixedly installed at the bottom of the mounting plate 102. A rotating shaft 202 is rotatably connected to the surface of the first U-shaped frame 201 to control the degree of bending of the steel bars and achieve the ideal construction state.

[0042] The fixing component 4 includes a fixing plate 401 fixedly installed on one side of the outer wall of the workbench 1. A first threaded rod 404 is rotatably connected inside the groove of the fixing plate 401 to fix the reinforcing bar and prevent bending errors.

[0043] The positioning component 5 includes a second U-shaped frame 501 fixedly installed on the other side of the outer wall of the workbench 1. Mounting frames 505 are fixedly installed on both sides of the second U-shaped frame 501, and the bending position can be adjusted according to different construction requirements, thereby improving the flexibility of the device.

[0044] Furthermore, a motor frame 211 is fixedly installed at the bottom of the first U-shaped frame 201, and a drive motor 203 is fixedly installed on the first U-shaped frame 201 through the motor frame 211. The top end of the rotating shaft 202 passes through the mounting plate 102, and a driven gear 208 is sleeved on the bottom of the rotating shaft 202. The driven gear 208 is set on the first U-shaped frame 201. A collar 209 is sleeved on the outer wall of the rotating shaft 202, and a connecting block 210 is welded on the collar 209. A movable column 204 is welded to one end of the connecting block 210. By utilizing the driving action of the gear, the transmission of force is made more stable and faster, thus accelerating the construction speed.

[0045] Furthermore, a mounting block 205 is fixedly installed on the top of the movable column 204, and a pair of first fixing rods 213 are fixedly installed on the top of the mounting block 205. Each first fixing rod 213 has a first fastening nut 214 threaded on its top. The first fastening nut 214 is set on the surface of the movable block 206. The movable block 206 is fixedly installed on the top of the mounting block 205. A first L-shaped frame 215 is fixedly installed on the movable block 206. A bending sleeve 207 is rotatably connected inside the first L-shaped frame 215. The output shaft of the drive motor 203 passes through the first U-shaped frame 201 and is fitted with a drive gear 212. The drive gear 212 meshes with the driven gear 208. The automatic bending of multiple steel bars is achieved by the rotation of the bending sleeve 207 in conjunction with the action of the central pin 101.

[0046] Furthermore, a front clamping plate 402 is fixedly installed on the fixed plate 401, a sliding rod 409 is fixedly installed on the sliding groove of the surface of the fixed plate 401, a rear clamping plate 403 is movably installed on one side of the surface of the fixed plate 401, a first handwheel 414 is fixedly installed at one end of the first threaded rod 404, a first slider 412 is installed on the external thread of the first threaded rod 404, the first slider 412 is fixedly installed at the middle position of the bottom of the movable plate 405, a third slider 416 is slidably installed on the sliding groove of the movable plate 405, an upper clamping plate 408 is fixedly installed at one end of the third slider 416, and a second L-shaped frame 407 is fixedly installed at the other end of the third slider 416. The second L-shaped frame 407 is located on one side of the movable plate 405. Through the cooperative action of the front clamping plate 402, the rear clamping plate 403 and the upper clamping plate 408, multiple steel bars are stacked and fixed, solving the problem that it is inconvenient to bend multiple steel bars at the same time.

[0047] As a further embodiment of this utility model, a second threaded rod 406 is threadedly installed between the second L-shaped frame 407 and the sliding groove of the fixed plate 401. A second handwheel 415 is fixedly installed at the top of the second threaded rod 406. Multiple protrusions 410 are welded to the bottom of the rear clamping plate 403. Each protrusion 410 is movably connected inside the groove of the fixed plate 401. A second slider 413 is movably sleeved on the outside of the sliding rod 409. The top of the second slider 413 is fixedly installed on both sides of the bottom of the moving plate 405, which improves the bending efficiency of the reinforcing bars and meets the construction requirements.

[0048] Furthermore, the top of the limiting plate 3 and the rear clamping plate 403 are jointly provided with a connecting strip 411. A pair of second fixing rods 302 are welded to one side of the limiting plate 3. One end of each second fixing rod 302 passes through the side of the fixing block 301. Multiple second fastening nuts 303 are threaded on the outside of the second fixing rod 302. A third fixing rod 304 is fixedly installed on the surface of the limiting plate 3 and the rear clamping plate 403. The top of the third fixing rod 304 passes through the connecting strip 411 and is threaded with a third fastening nut 305. The third fastening nut 305 is set on the surface of the connecting strip 411, which is conducive to tight structural connection and makes the steel bar stable during bending.

[0049] Furthermore, a third threaded rod 502 is threaded inside the second U-shaped frame 501, and a triangular plate 507 is fixedly connected to the bottom of the second U-shaped frame 501. A third handwheel 509 is fixedly installed at one end of the third threaded rod 502, which rotates through one end of the second U-shaped frame 501. A fourth slider 510 is slidably installed outside the third threaded rod 502. A third L-shaped frame 503 is movably connected above the second U-shaped frame 501 via the third threaded rod 502. A positioning plate 504 is fixedly installed on one side of the third L-shaped frame 503. A fifth slider 512 is movably connected inside the mounting frame 505. A distance scale line 511 is engraved on the top of the mounting frame 505. The positioning plate 504 is driven by the third frame to position the length of the reinforcing bar on the workbench 1, which facilitates the adjustment of the bending position of the reinforcing bar.

[0050] Furthermore, the top of the fourth slider 510 is fixedly installed on the bottom of the third L-shaped frame 503, and a positioning block 506 is fixedly installed on one side of the fifth slider 512. A fourth fixing rod 513 is fixedly installed on the bottom of the fifth slider 512. The bottom end of the fourth fixing rod 513 passes through the mounting frame 505 and is threaded with a fourth fastening nut 514. A connecting plate 508 is welded to one side of the triangular plate 507. One side of the connecting plate 508 is fixedly installed on the outer wall of the workbench 1. An L-shaped pointer 515 is fixedly installed on the other side of the fifth slider 512, which improves the positioning accuracy and ensures the work quality.

[0051] The specific working method is as follows: First, stack the reinforcing bars between the front clamping plate 402 and the rear clamping plate 403, and rotate the first handwheel 414. The first handwheel 414 drives the first threaded rod 404 to move. The first threaded rod 404 drives the upper clamping plate 408 to move longitudinally through the first slider 412 and the moving plate 405, so that the upper clamping plate 408 is positioned above the reinforcing bars. Then, rotate the second handwheel 415. The second handwheel 415 drives the second threaded rod 406 to rotate. The second threaded rod 406 drives the upper clamping plate 408 to move vertically through the second L-shaped frame 407, so that the upper clamping plate 408 abuts against the top of the uppermost reinforcing bar, realizing the stacking of multiple reinforcing bars. Finally, start the drive motor 203. The output shaft of the drive motor 203 drives the moving column 204 and the bending sleeve 207 to rotate through the rotating shaft 202. The rotation of the bending sleeve 207 cooperates with the center pin 101. The function enables automatic bending of multiple steel bars. For steel bar adjustment, tightening the fourth fastening nut 514 separates it from the mounting frame 505 and pushes the positioning block 506, causing it to move laterally in a straight line. Through the coordination of the distance scale line 511 and the L-shaped pointer 515, the positioning block 506 moves to the designated position. Tightening the fourth fastening nut 514 again brings it into contact with the bottom of the mounting frame 505. Then, rotating the third handwheel 509 drives the third threaded rod 502, which in turn drives the third L-shaped frame 503 and the positioning plate 504 via the fourth slider 510. The fourth slider 510 stops moving when it contacts the positioning block 506, at which point the positioning plate 504 moves to the designated position on the top of the worktable 1, facilitating the adjustment of the steel bar length on the worktable 1.
