Description

Technical Field

[0001] This utility model relates to the field of rebar bending technology, and in particular to an adjustable rebar bending machine. Background Technology

[0002] A rebar bending machine is a specialized piece of machinery used for bending rebar. It is widely used in construction, bridge, tunnel and other engineering fields. Driven by a motor, it bends and shapes rebar, and can efficiently complete tasks such as prestressed rebar processing, column rebar and beam rebar fabrication. It features rapid rebar forming, high processing accuracy and high degree of automation, significantly improving production efficiency and reducing labor intensity. It is an important piece of equipment in the modern rebar processing industry.

[0003] Existing rebar bending machines have difficulty adjusting the gap between the placed rebars. When bending rebars of different diameters, operators simply place them directly into the gap and then drive the rebar bending machine to bend them. This bending method prevents the gap from being close to the radial surface of the rebar, resulting in a large deviation in the bent rebar. Furthermore, when bending multiple stacked rebars, the rebars stacked along the height direction are prone to tipping over, causing poor rebar bending. Utility Model Content

[0004] In order to overcome the problem that existing rebar bending machines are not easy to adjust the gap between rebars, and are prone to tipping over when bending multiple stacked rebars, resulting in poor bending, the following measures are needed.

Plate three is located on the rear side of the rotating block. The front side of plate three has a circular groove into which a push rod can be inserted. The rear side of plate three has a bolt that meshes with the rotating block.

[0008] Preferably, the front side of the push rod in the axial direction can be fitted with an insert block, and the top of the rotating block is provided with a slot corresponding to the insert block.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5This utility model provides an embodiment: an adjustable rebar bending machine, including a worktable 1, a pad 5 installed on the left side of the top of the worktable 1, a rotatable rotating block 2 on the right side of the pad 5, a limiting post 62 installed on the top of the rotating block 2, the rotating block 2 rotating around the axis of the limiting post 62, a plate 453 on the rear side of the top of the rotating block 2 corresponding to the limiting post 62, the rotating block 2 and the plate 453 being connected by a second adjustment assembly, the second adjustment assembly including a top rod 211, a rearwardly protruding plate 452 on the rear side of the plate 453, a downwardly protruding plate 451 at the bottom of the plate 452, and a top... The rear side of rod 211 in the axial direction can abut against plate 3 451 to prevent plate 3 451 from moving forward. A plate 6 44 that can move back and forth is provided on the left side of plate 5 453. The top of plate 6 44 and the top of plate 5 453 are jointly provided with a first adjusting assembly. The first adjusting assembly includes a U-shaped groove 1 441 on the top of plate 6 44, and a U-shaped groove 2 4531 on the top of plate 5 453. The position of plate 3 451 can be adjusted by the top rod 211 of the second adjusting assembly, thereby adjusting the position of plate 5 453, so that the radial surface of the limiting column 2 62 and the front side of plate 5 453 can clamp the reinforcing bar that needs to be bent. The tightness allows the reinforcing bars to be stacked along the height direction without collapsing. Different lengths of top rods 211 can accommodate reinforcing bars of different diameters, increasing applicability. The first adjusting component allows plate six 44 and plate five 453 to move together, ensuring the front side of plate six 44 is flush with the front side of plate five 453, facilitating the radial surface of the reinforcing bars to be flat. Positioning blocks can be inserted into U-shaped groove one 441 and U-shaped groove two 4531. When the positioning blocks are inserted into U-shaped groove one 441 and U-shaped groove two 4531, the front surface of plate six 44 is flush with the front surface of plate five 453. The positioning blocks, inserted into U-shaped groove one 441 and U-shaped groove two 4531, effectively... The joint movement of plate 644 and plate 5453 requires the positioning block to be pulled out when bending the reinforcing bars. The right side of the rotating block 2 is a rectangular block structure with a through-hole 21 on the front side. The bottom of plate 452 can fit against the top of the rotating block 2. Plate 3451 is located behind the rotating block 2. The front side of plate 3451 has a circular groove 4511 into which the top rod 211 can be inserted. The rear side of plate 3451 is fitted with a bolt 4512 that meshes with the rotating block 2. By inserting the top rod 211 into the circular groove 4511, the top rod 211 and the bolt 4512 jointly bear the reverse force during the bending process of the reinforcing bars, increasing the strength.

[0021] Please see Figure 2 - Figure 5In this embodiment, the front side of the top rod 211 in the axial direction can be fitted with the insert block 221. The top of the rotating block 2 is provided with a slot 22 corresponding to the insert block 221. By inserting the insert block 221 into the slot 22, the front side of the top rod 211 in the axial direction is blocked, so that the bolt 4512 can fix the plate 3 451. A motor 23 is installed at the bottom of the worktable 1 at the position corresponding to the position of the limiting post 2 62. A limiting post 1 61 is installed on the left side of the top of the worktable 1 corresponding to the position of the limiting post 2 62. The motor 23 can drive the rotating block 2 to rotate, so that the limiting post 2 62 and the plate 5 453 drive one side of the reinforcing bar to bend. A plate 1 41 is provided on the rear side of the top of the worktable 1 corresponding to the plate 6 44. A plate 2 42 is provided on the top of the plate 1. A guide rod 431 is inserted in the plate 2 42. The front side of the guide rod 431 in the axial direction is fixedly connected to the rear side of the plate 6 44. The rear side of the plate 6 44 A threaded rod 432 passing through plate 2 42 is also fixed on the side. The front side of plate 2 42 is provided with a through hole corresponding to the threaded rod 432. Clamping nuts 4321 are attached to the front and rear sides of the threaded rod 432 corresponding to plate 2 42. The threaded rod 432 can move back and forth without being turned through the through hole, which facilitates the adjustment and movement of plate 6 44. The two clamping nuts 4321 can fix the threaded rod 432, so that plate 6 44 can withstand the reverse force generated by the bending of the steel bar. The top of the limiting post 1 61 is provided with a hexagonal hole 1 611, and the top of the limiting post 2 62 is provided with a hexagonal hole 2 621. The bottom of the worktable 1 is provided with a support leg 11 for support. The bottom of the limiting post 1 61 and the limiting post 2 62 are respectively provided with studs. The hexagonal hole 1 611 can fix the limiting post 1 61 on the worktable 1, and the hexagonal hole 2 621 can fix the limiting post 2 62 on the rotating block 2.

[0022] During operation, different lengths of top rods 211 are selected according to the different diameters of the reinforcing bars to ensure that the limiting column 2 62 and plate 5 453 are in contact with the radial surface of the reinforcing bars. The operator tightens the clamping nut 4321 to move it away from plate 2 42. Then, the positioning block is inserted into U-shaped groove 1 441 and U-shaped groove 2 4531. Next, the top rod 211 is inserted into the insertion hole 21, and the insertion block 221 is inserted into the slot 22. Then, the front side of the top rod 211 is in contact with the rear side of the insertion block 221 to prevent the top rod 211 from moving forward. Then, the bolt 4512 is tightened to make the front side of plate 3 451 contact the top rod 211. When positioning plate 3 451, the plate Plate 453 moves along with the positioning block, and Plate 64 also moves simultaneously. After the position of Plate 5453 is adjusted, the position of Plate 64 is also adjusted. The operator directly rotates the clamping nut 4321 so that the clamping nuts 4321 on both sides are in close contact with Plate 242. The operator takes the steel bar and places it on top of the pad 5 and the rotating block 2, so that the limiting post 1 61 and Plate 64 fit and limit the steel bar. The limiting post 2 62 and Plate 5453 also limit the steel bar at the same time. Here, steel bars can continue to be stacked along the height direction, but no more than five bars. Remove the positioning block from U-shaped groove 1 441, and then drive the motor 23 to make the rotating block 2 rotate. This completes the bending of the steel bar.

[0023] Through the above steps, the top rod 211 of the second adjusting component can adjust the position of plate three 451, and then adjust the position of plate five 453, so that the radial surface of the limiting column two 62 and the front side of plate five 453 can clamp the steel bar that needs to be bent. The top rods 211 of different lengths can correspond to steel bars of different diameters. The first adjusting component can make plate six 44 and plate five 453 move together, which can ensure that the front side of plate six 44 is flush with the front side of plate five 453, so as to solve the problem that the steel bar bending machine in the prior art is not easy to adjust the gap between steel bars, and is prone to tipping over when bending multiple steel bars stacked together, resulting in poor bending.
