[0001] This utility model relates to the field of steel bar processing equipment, and in particular to a multi-functional steel bar bending machine. Background Technology

[0002] Reinforcing bars are widely used in construction projects such as bridges, houses, and roads. When using reinforcing bars, they often need to be bent to facilitate their positioning and fixation with other components. Therefore, bending machines are used to bend the reinforcing bars into the required shapes and sizes.

[0003] A search revealed, for example, a utility model with publication number CN211331085U, which describes a rebar bending machine. The machine includes a body, a working disc rotatably connected to the body, a mandrel at the center of the working disc, a bending shaft on the working disc, and a support shaft on the body. However, this utility model relies on manual judgment to bend the rebar, which can easily lead to errors in the bending angle. Furthermore, when the rebar is under stress, the end of the rebar tends to tilt vertically, affecting the degree of bending and the quality of the bending. Therefore, to address these shortcomings, the inventor proposes a multi-functional rebar bending machine. Utility Model Content

[0004] The main purpose of this utility model is to provide a multi-functional rebar bending machine, which can effectively solve the problems of errors easily generated during the bending process of existing bending machines and the rebar ends easily tilting in the vertical direction.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A multi-functional rebar bending machine includes a worktable, a work plate rotatably connected to the top surface of the worktable, and a placement block fixedly connected to the top surface of the worktable. The top surface of the work plate has a central shaft in the middle, and multiple placement holes are opened on the top surface of the work plate. Limiting shafts are provided inside the placement holes. The top surface of the worktable has scale lines. A guide plate is fixedly installed on the side of the work plate. A circular guide rail is fixedly installed on the top surface of the worktable, and a slider is slidably connected to the outer surface of the circular guide rail. A stop bar is fixedly installed on the top surface of the slider, and limit bolts are threaded to both sides of the outer surface of the slider. A limit component is provided on the top surface of the limit shaft.

[0006] Preferably, the limiting component includes a telescopic sleeve fixedly installed on the top of the limiting shaft, a movable plate slidably connected inside the telescopic sleeve, an adjustment hole on the outer top surface of the telescopic sleeve, and a plurality of equally spaced fixing holes on the top surface of the movable plate.

[0007] Preferably, the top surface of the movable plate is threadedly connected to a first threaded rod, the bottom end of the first threaded rod is rotatably connected to a limit plate, and the top end of the first threaded rod is fixedly installed with a rotating handle. A telescopic rod is fixedly installed on one side of the bottom surface of the movable plate, and the telescopic rod is fixedly connected to the limit plate.

[0008] Preferably, the bottom surface of the limiting plate is provided with multiple ball bearings.

[0009] Preferably, a movable block is fixedly installed on one side of the top surface of the workbench, a second threaded rod is rotatably connected to one side of the inner surface of the movable block, and a slide rod is fixedly installed on the other side of the inner surface of the movable block. A support block is threadedly connected to the outer surface of the second threaded rod, and the support block is slidably connected to the slide rod.

[0010] Preferably, a fixing frame is fixedly installed on the top surface of the support block, and a fastening bolt is threadedly connected to the top surface of the fixing frame.

[0011] Preferably, one end of the second threaded rod extends to the outside of the moving block and is fixedly fitted with a handle.

[0012] Preferably, the circular guide rail is located on the outside of the working disk, and the circular guide rail coincides with the center of the working disk.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This utility model discloses a multi-functional rebar bending machine, which, by setting up a worktable, enables the following in actual work: 1. The worker passes the reinforcing bar through the fixed frame and extends it between the central axis and the limiting axis. Then, the worker pushes the slider to move it along the circular guide rail. The worker observes the angle between the guide plate and the stop bar according to the scale lines. When the working disc rotates, causing the central axis and the limiting axis to bend the reinforcing bar, the working disc will drive the guide plate to rotate. When the guide plate contacts the stop bar, the worker can manually control the machine to stop. By pre-setting the required rotation angle of the working disc, the bending angle error caused by manual judgment during the bending process can be effectively reduced.

[0014] 2. Once the reinforcing bar extends between the central axis and the limiting axis, the handle can be rotated to rotate the first threaded rod. As the first threaded rod rotates, it will push the limiting plate down until the ball bearings on the bottom surface of the limiting plate contact the reinforcing bar. When the end of the reinforcing bar tends to curl upwards, the limiting plate will abut against the reinforcing bar, which can play a good limiting role, thereby effectively reducing the possibility of the end of the reinforcing bar curling upwards and improving the bending quality of the reinforcing bar.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] This utility model discloses a multifunctional rebar bending machine, such as Figure 1-8 As shown, the device includes a workbench 1, a work plate 2 rotatably connected to the top surface of the workbench 1, and a placement block 3 fixedly connected to the top surface of the workbench 1. A central shaft 4 is provided in the center of the top surface of the work plate 2, and multiple placement holes 6 are opened on the top surface of the work plate 2. A limiting shaft 5 is provided inside the placement hole 6. After the workbench 1 is started, the motor inside the workbench 1 will provide rotational power, which will be transmitted to the work plate 2 through the gearbox and pulley, causing the work plate 2 to rotate. When the work plate 2 rotates, the central shaft 4 and the limiting shaft 5 can bend the steel bar. The above operation method and the required components are all existing technologies, and therefore will not be described in detail here.

[0019] The top surface of the workbench 1 is provided with scale lines 201, and the side of the work plate 2 is fixedly installed with a guide plate 202. When the work plate 2 rotates, the guide plate 202 will point to different positions of the scale lines 201 as the work plate 2 rotates, so that the staff can intuitively see the angle of rotation of the work plate 2.

[0020] A circular guide rail 203 is fixedly installed on the top surface of the workbench 1. The circular guide rail 203 is located on the outside of the work plate 2, and the center of the circular guide rail 203 coincides with that of the work plate 2.

[0021] Furthermore, a slider 2031 is slidably connected to the outer surface of the circular guide rail 203, a stop bar 2033 is fixedly installed on the top surface of the slider 2031, and limit bolts 2032 are threadedly connected to both sides of the outer surface of the slider 2031, allowing the slider 2031 to move along the circular guide.

[0022] The worker places the steel bar between the central shaft 4 and the limiting shaft 5, and pushes the slider 2031 to move it along the circular guide rail 203. According to the scale line 201 set therein, the worker observes the angle between the indicator plate 202 and the stop bar 2033 until the angle between the indicator plate 202 and the stop bar 2033 is the required angle.

[0023] When the working disc 2 rotates, causing the central shaft 4 and the limiting shaft 5 to bend the steel bar, the working disc 2 will drive the guide plate 202 to rotate. When the guide plate 202 contacts the stop bar 2033, the operator can manually control the machine to stop. By pre-setting the required rotation angle of the working disc 2, the bending angle error caused by manual judgment during the bending process can be effectively reduced.

[0024] A telescopic sleeve 501 is fixedly installed at the top of the limiting shaft 5. A movable plate 502 is slidably connected inside the telescopic sleeve 501. An adjustment hole 504 is opened on the outer top surface of the telescopic sleeve 501. A plurality of equally spaced fixing holes 503 are opened on the top surface of the movable plate 502. When the movable plate 502 moves inside the telescopic sleeve 501, the plurality of fixing holes 503 will coincide with the adjustment hole 504 in sequence. The movable plate 502 can be fixed by inserting bolts into the overlapping adjustment hole 504 and fixing hole 503.

[0025] The top surface of the movable plate 502 is threadedly connected to a first threaded rod 506. The bottom end of the first threaded rod 506 is rotatably connected to a limit plate 508, and a handle 505 is fixedly installed at the top end of the first threaded rod 506. A telescopic rod 507 is fixedly installed on one side of the bottom surface of the movable plate 502, and the telescopic rod 507 is fixedly connected to the limit plate 508. When the operator holds and rotates the handle 505, the first threaded rod 506 can be rotated. As the first threaded rod 506 rotates, the limit plate 508 will rise and fall. When the limit plate 508 rises and falls, it will drive the telescopic rod 507 to extend and retract. The telescopic rod 507 can guide the rise and fall of the limit plate 508.

[0026] The bottom surface of the limiting plate 508 is provided with multiple balls 509. When the reinforcing bar extends between the central shaft 4 and the limiting shaft 5, the operator can rotate the handle 505 to rotate the first threaded rod 506. As the first threaded rod 506 rotates, it will push the limiting plate 508 down until the balls 509 on the bottom surface of the limiting plate 508 contact the reinforcing bar. When the reinforcing bar is bent and its end tends to curl upwards, the limiting plate 508 will abut against the reinforcing bar, which can play a good limiting role, thereby effectively reducing the possibility of the end of the reinforcing bar curling upwards and improving the bending quality of the reinforcing bar.

[0027] A movable block 101 is fixedly installed on one side of the top surface of the workbench 1. A second threaded rod 102 is rotatably connected to one side of the interior of the movable block 101, and a slide rod 103 is fixedly installed on the other side of the interior of the movable block 101. A support block 104 is threadedly connected to the outer surface of the second threaded rod 102, and the support block 104 is slidably connected to the slide rod 103. One end of the second threaded rod 102 extends to the outside of the movable block 101 and is fixedly installed with a handle. When the operator manually rotates the handle, the second threaded rod 102 can be rotated, and the support block 104 will move along the slide rod 103 due to the rotation of the second threaded rod 102.

[0028] A fixing frame 105 is fixedly installed on the top surface of the support block 104. A fastening bolt 1051 is threadedly connected to the top surface of the fixing frame 105. The reinforcing bar is inserted into the fixing frame 105 and the fastening bolt 1051 is rotated to hold the reinforcing bar in the fixing frame 105 in place, so as to effectively prevent the reinforcing bar from bending at a position inconsistent with the pre-design due to axial movement when bending.

[0029] The working principle of this utility model is as follows: the worker passes the steel bar through the fixed frame 105 and rotates the fastening bolt 1051 to hold the steel bar in the fixed frame 105 in place until the steel bar extends between the central shaft 4 and the limiting shaft 5. Then, as needed, the slider 2031 is pushed to move along the circular guide rail 203. The angle between the indicator plate 202 and the stop bar 2033 is observed according to the scale line 201 provided thereon until the angle between the indicator plate 202 and the stop bar 2033 is the required angle.

[0030] Once the reinforcing bar extends between the central shaft 4 and the limiting shaft 5, the handle 505 can be rotated to rotate the first threaded rod 506. As the first threaded rod 506 rotates, it will push the limiting plate 508 down until the ball bearing 509 on the bottom surface of the limiting plate 508 contacts the reinforcing bar. Then, the working disc 2 rotates, causing the central shaft 4 and the limiting shaft 5 to bend the reinforcing bar. The working disc 2 will then drive the guide plate 202 to rotate. When the guide plate 202 contacts the stop bar 2033, the operator can manually control the machine to stop and remove the reinforcing bar.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
