Description

Technical Field

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

[0002] A rebar bending machine, also known as a rebar bending machine, is mainly used for the precise bending of rebar. It is widely used in various engineering scenarios such as construction, bridges, and tunnels. It can bend straight rebar into specific angles and shapes according to engineering requirements, thereby meeting the rebar configuration requirements of different structural components and greatly improving construction efficiency and rebar processing quality.

[0003] A search revealed Chinese patent publication number CN210450713U, which discloses a rebar bending machine. This invention relates to the technical field of rebar bending and solves the problem of rebars easily bouncing off the rotating disc and injuring people during bending. The key technical points include a worktable, a rotating disc rotatably connected to the top of the worktable and driven by a motor within the worktable, a column fixedly connected to the center of the rotating disc, a clamping block located on one side of the rotating disc on the worktable, and a push rod located near the outer periphery of the rotating disc and rotating with it. The horizontally positioned pressure plate on the side of the clamping block near the column, the guide tubes fixedly connected to both sides of the top of the column and the top of the push rod, and the pressure rod set between the two guide tubes at the top of the column, together with the pressure plate on the clamping block and the pressure rods on the column and push rod, limit the movement of the reinforcing bar. This prevents the reinforcing bar from bouncing off the rotating plate during bending, thus reducing the risk of injury to the operator. However, due to the setting of the pressure plate on the clamping block and the pressure rods on the column and push rod, the size of the reinforcing bar is relatively fixed when limiting its movement, making it difficult to accommodate reinforcing bars of various sizes.

[0004] Different engineering projects use a variety of steel bars with varying thicknesses. The existing limiting structure of this bending machine cannot be flexibly adjusted to match steel bars of different sizes. When dealing with thicker steel bars, it may not be able to fix them effectively due to insufficient limiting space. For thinner steel bars, the limiting may be too loose, causing the steel bar position to be unstable during bending, affecting bending accuracy, and even potentially posing safety hazards. This limits the applicability of the steel bar bending machine to a certain extent and reduces its practicality in diverse construction scenarios. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rebar bending machine, which aims to improve the problem that the existing technology is difficult to adapt to rebars of various sizes.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rebar bending machine, comprising a workbench, a rebar conveying box fixedly connected to the top rear side of the workbench, multiple conveying rollers rotatably connected at equal intervals to the bottom rear side of the rebar conveying box, a fixing block fixedly connected to the top front side of the workbench, hydraulic rods fixedly connected to the left and right rear ends of the fixing block, the output ends of the two hydraulic rods penetrating through the interior of the rebar conveying box and fixedly connected to a C-shaped plate, multiple adjusting rollers rotatably connected at equal intervals inside the C-shaped plate, a rotating disk fixedly installed at the top right rear end of the workbench, a working roller fixedly connected to the center of the top wall of the rotating disk, a bending roller fixedly connected to the top front side of the rotating disk, a rebar pushing assembly provided on the top left side of the workbench, and a rebar locking mechanism provided on the top of the rebar conveying box.

[0007] The above technical solution automatically pushes the steel bars to the bending area using a steel bar pushing component. The hydraulic rod drives the C-shaped plate and adjusting rollers to clamp and position the ends of the steel bars. The rotating disc drives the working roller and bending roller to apply bending force to the steel bars, achieving efficient, precise and safe bending processing of steel bars. It eliminates the need for direct manual contact, greatly improving safety, and can adapt to steel bars of different sizes to meet diverse processing needs.

[0008] As a further description of the above technical solution:

[0009] The rebar locking mechanism includes a pressure plate, which is set on the top of the rebar conveying box. Handles are fixedly connected to the left and right sides of the top of the pressure plate. Hexagonal cone heads are fixedly connected at equal intervals to the bottom of the pressure plate. Multiple insertion holes are equally spaced on the top of the rebar conveying box. Hexagonal cone grooves are formed on the top of multiple conveying rollers. The bottom of the multiple hexagonal cone grooves is a regular hexagonal groove, and the top is a hexagonal cone groove. The size of the multiple hexagonal cone heads matches the size inside the multiple hexagonal cone grooves.

[0010] The above technical solution achieves precise positioning of the reinforcing bars during conveying and bending by pressing the pressure plate to embed the hexagonal cone head into the hexagonal cone groove, thus restricting the rotation of the conveying rollers. This ensures the accuracy of the bending angle and shape, improves processing quality, facilitates operation, and enhances processing efficiency and safety.

[0011] As a further description of the above technical solution:

[0012] The rebar pushing assembly includes a moving groove, which is located on the top left side of the workbench. An L-shaped support plate is provided inside the moving groove. A U-shaped groove is provided on the top of the L-shaped support plate. A drive motor is fixedly installed at the bottom of the L-shaped support plate. A transmission gear is fixedly connected to the output end of the drive motor. An L-shaped rack is fixedly connected to the bottom front side of the workbench. The transmission gear and the L-shaped rack are meshed with each other.

[0013] The above technical solution involves an L-shaped support plate inside the moving trough, with a U-shaped groove at the top. The drive motor installed at the bottom meshes with the L-shaped rack through the transmission gear at the output end, accurately conveying the steel bars to the bending processing position. This eliminates the need for manual operation, improving work efficiency and accuracy, and ensuring consistency in each push.

[0014] As a further description of the above technical solution:

[0015] A controller is fixedly installed on the top front right end of the workbench. The controller is electrically connected to two hydraulic rods, a rotating disk, and a drive motor.

[0016] Through the above technical solution, the controller is electrically connected to two hydraulic rods, a rotating disk, and a drive motor, which can precisely coordinate the action sequence and timing of each component. This ensures that the extension and retraction of the hydraulic rods, the rotation of the rotating disk, and the driving of the drive motor work in coordination, thereby achieving automation and precision in steel bar bending processing and improving processing quality and production efficiency.

[0017] As a further description of the above technical solution:

[0018] Two supports are fixedly connected to the top right side of the workbench, and tempered glass baffles are fixedly connected to the rear side of each of the two supports.

[0019] Through the above technical solution, the tempered glass baffles fixed to the rear of the two supports can play a protective role during the processing, protecting the safety of the operators.

[0020] As a further description of the above technical solution:

[0021] Multiple material stop bars are fixedly connected to the top left front end of the workbench, and diagonal braces are fixedly connected to the outer walls of the multiple material stop bars on the side away from each other.

[0022] The above technical solution involves multiple material stops and diagonal braces on the front left side of the top of the workbench, which mainly limit the position of the reinforcing steel materials to prevent them from shifting or tipping over during storage.

[0023] As a further description of the above technical solution:

[0024] Anti-slip pads are fixedly connected to the four corners of the bottom of the workbench, and the bottoms of the multiple anti-slip pads are all designed to be anti-slip.

[0025] The above technical solution involves using anti-slip pads at the four corners of the workbench, which effectively increases the friction between the equipment and the ground, ensuring that the equipment remains stable during operation and does not slide or shake.

[0026] As a further description of the above technical solution:

[0027] The outer walls of the multiple conveying rollers and multiple adjusting rollers are all designed with an arc shape and are made of hard rubber.

[0028] The above technical solution involves multiple conveying rollers and adjusting rollers with an arc-shaped outer wall and made of hard rubber, which can better fit the surface of the steel bar. The hard rubber material reduces friction with the steel bar and provides sufficient clamping force to ensure the smooth conveying and precise bending of the steel bar.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, the steel bar is automatically pushed to the bending area by the steel bar pushing component. The hydraulic rod drives the C-shaped plate and the adjusting roller to clamp and position the end of the steel bar. The rotating disk drives the working roller and the bending roller to apply bending force to the steel bar, realizing efficient, accurate and safe bending processing of the steel bar. No direct manual contact is required, which greatly improves safety and can adapt to steel bars of different sizes to meet diverse processing needs.

[0031] 2. In this utility model, by pressing the pressure plate to embed the hexagonal cone head into the hexagonal cone groove to restrict the rotation of the conveying roller, the position of the steel bar is accurately fixed during the conveying and bending process, ensuring the accuracy of the bending angle and shape, improving the processing quality, and at the same time facilitating operation, improving processing efficiency and safety.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a rebar bending machine, including a workbench 1, a rebar conveying box 3 fixedly connected to the top rear side of the workbench 1, multiple conveying rollers 4 equidistantly rotatably connected to the bottom rear side of the rebar conveying box 3, a fixing block 5 fixedly connected to the top front side of the workbench 1, hydraulic rods 6 fixedly connected to the left and right rear ends of the fixing block 5, the output ends of the two hydraulic rods 6 passing through the inside of the rebar conveying box 3 and fixedly connected to a C-shaped plate 7, multiple adjusting rollers 8 equidistantly rotatably connected inside the C-shaped plate 7, a rotating disk 9 fixedly installed at the top right rear end of the workbench 1, a working roller 10 fixedly connected to the center of the top wall of the rotating disk 9, a bending roller 11 fixedly connected to the top front side of the rotating disk 9, a rebar pushing assembly provided on the top left side of the workbench 1, and a rebar locking mechanism 2 provided on the top of the rebar conveying box 3.

[0041] Specifically, the steel bars to be processed are placed on the workbench 1. Multiple conveying rollers 4, equidistantly rotatable at the rear bottom of the steel bar conveying box 3 at the top, reduce friction between the steel bars and the conveying box, allowing the steel bars to move smoothly to the right within the box. The steel bar pushing assembly automatically pushes the steel bars to the bending position. When the steel bars reach the predetermined position, the hydraulic rods 6 at the left and right rear ends of the fixing block 5 begin to operate. The output ends of the hydraulic rods 6 penetrate the interior of the steel bar conveying box 3 and drive the C-shaped plate 7 to move. Multiple adjusting rollers 8, equidistantly rotatable inside the C-shaped plate 7, rotate with the movement of the steel bars upon contact, thereby clamping and positioning the ends of the steel bars. The adjusting rollers 8 can adaptively adjust according to the size of the steel bars, ensuring stable operation for steel bars of different sizes. With the clamping force of the steel bar, after the steel bar is firmly clamped, the rotating disk 9 at the rear right side of the top of the workbench 1 begins to rotate. The working roller 10 in the center of the top wall of the rotating disk 9 and the bending roller 11 on the front side of the top contact the steel bar. The working roller 10, as the main support and positioning component, provides a reference point for bending the steel bar. The bending roller 11, driven by the rotating disk 9, applies bending force to the steel bar, causing the steel bar to bend according to a predetermined angle and shape. In the entire bending process, the pushing, clamping and bending of the steel bar are all completed automatically. The operator does not need to directly contact the steel bar being processed, which greatly improves the safety of the work. At the same time, because the hydraulic rod 6 drives the adjusting roller 8 to move, it can adapt to steel bars of different sizes, meet diverse processing needs, and realize efficient, accurate and safe steel bar bending processing.

[0042] Reference Figure 1 , Figure 3 and Figure 4 The rebar locking mechanism 2 includes a pressure plate 201, which is set on the top of the rebar conveying box 3. The pressure plate 201 is fixedly connected to the left and right sides of the top of the pressure plate 201. The bottom of the pressure plate 201 is fixedly connected to hexagonal cone heads 203 at equal intervals. The top of the rebar conveying box 3 is provided with multiple insertion holes 204 at equal intervals. The top of multiple conveying rollers 4 is provided with hexagonal cone grooves 205. The bottom of the multiple hexagonal cone grooves 205 is a regular hexagonal groove and the top is a hexagonal cone groove. The size of the multiple hexagonal cone heads 203 matches the size inside the multiple hexagonal cone grooves 205 respectively.

[0043] Specifically, when the steel bars to be processed are placed in the steel bar conveying box 3, the operator places them inside. At this time, the steel bars come into contact with the conveying rollers 4. The conveying rollers 4 reduce the friction between the steel bars and the conveying box by their own rotation, allowing the steel bars to move relatively smoothly within the conveying box. After the steel bars are in place, the operator holds the handle 202 and presses the pressure plate 201 downwards. As the pressure plate 201 is pressed down, the hexagonal cone head 203 at its bottom accurately inserts into the insertion hole 204 at the top of the steel bar conveying box 3. The hexagonal cone head 203 continues to move downwards until it is completely embedded in the hexagonal cone groove 205 at the top of the conveying rollers 4. Since the size of the hexagonal cone head 203 matches the internal size of the multiple hexagonal cone grooves 205, when the hexagonal cone head 203 is inserted into the hexagonal cone groove 205, it restricts the rotation of the conveying rollers 4. This restriction effectively prevents the steel bars from being bent during conveying and subsequent bending processes. In the event of an unexpected movement, the hexagonal conical groove 205 on the top of the conveying roller 4, with its bottom being a regular hexagonal groove and its top being a hexagonal conical groove, not only provides accurate guidance for the insertion of the hexagonal conical head 203, but also allows the hexagonal conical head 203 to fit tightly, increasing the stability and reliability of the locking. During the bending process of the rebar, the hydraulic rod 6 drives the C-shaped plate 7 to move, and the adjusting roller 8 clamps and positions the end of the rebar. At the same time, the rotating disk 9 drives the working roller 10 and the bending roller 11 to apply bending force to the rebar. Due to the action of the rebar locking mechanism 2, the rebar remains in the predetermined position throughout the bending process without slipping or shifting, thus ensuring the accuracy of the bending angle and shape. After the rebar bending is completed, the operator holds the handle 202 again to lift the pressure plate 201 upward, causing the hexagonal conical head 203 to be pulled out of the hexagonal conical groove 205, releasing the locking of the rebar and facilitating the removal of the processed rebar.

[0044] Reference Figure 1 , Figure 3 and Figure 5The rebar pushing assembly includes a moving groove 12, which is located on the top left side of the workbench 1. An L-shaped support plate 13 is installed inside the moving groove 12. A U-shaped groove 14 is formed at the top of the L-shaped support plate 13. A drive motor 15 is fixedly installed at the bottom of the L-shaped support plate 13. A transmission gear 16 is fixedly connected to the output end of the drive motor 15. An L-shaped rack 17 is fixedly connected to the front bottom of the workbench 1, and the transmission gear 16 and the L-shaped rack 17 mesh with each other. A controller 18 is fixedly installed at the right front top of the workbench 1. The controller 18 is connected to two hydraulic rods 6 and a rotary... The moving plate 9 and the drive motor 15 are electrically connected; two brackets 19 are fixedly connected to the top right side of the worktable 1, and tempered glass baffles 20 are fixedly connected to the rear side of each bracket 19; multiple material stop bars 21 are fixedly connected to the front left side of the top of the worktable 1, and diagonal braces 22 are fixedly connected to the outer walls of the multiple material stop bars 21 on the side away from each other; anti-slip pads 23 are fixedly connected to the four corners of the bottom of the worktable 1, and the bottom of the multiple anti-slip pads 23 are all designed to be anti-slip; the outer walls of the multiple conveying rollers 4 and the multiple adjusting rollers 8 are all designed with arc shape and are made of hard rubber.

[0045] Specifically, the moving groove 12 in the rebar pushing assembly is equipped with an L-shaped abutment 13, with a U-shaped groove 14 at its top. The drive motor 15 installed at the bottom meshes with the L-shaped rack 17 through the transmission gear 16 at its output end, accurately conveying the rebar to the bending processing position. This eliminates the need for manual operation, improving work efficiency and precision, and ensuring consistency in each push. The controller 18 is electrically connected to the two hydraulic rods 6, the rotating disk 9, and the drive motor 15, respectively, and can precisely coordinate the action sequence and timing of each component. This ensures that the extension and retraction of the hydraulic rods 6, the rotation of the rotating disk 9, and the pushing work of the drive motor 15 work together to achieve automation and precision in rebar bending processing, improving processing quality and production efficiency. The two supports 19 are located behind... The side-fixed tempered glass baffle 20 provides protection during processing, ensuring the safety of operators. Multiple material stops 21 and diagonal braces 22 on the front left side of the top of the workbench 1 mainly limit the position of the reinforcing steel, preventing it from shifting or tipping over during storage. The anti-slip pads 23 at the four corners of the bottom of the workbench 1 have an anti-slip design, which can effectively increase the friction between the equipment and the ground, ensuring that the equipment remains stable during operation and does not slip or shake. The outer walls of the multiple conveying rollers 4 and adjusting rollers 8 are made of arc-shaped material and hard rubber, which can better fit the surface of the reinforcing steel. The hard rubber material reduces friction with the reinforcing steel while providing sufficient clamping force to ensure smooth conveying and precise bending of the reinforcing steel.

[0046] Working principle: The steel bars to be processed are placed on the workbench 1. Multiple conveying rollers 4, equidistantly rotatable at the bottom rear side of the steel bar conveying box 3 at the top, reduce friction between the steel bar and the conveying box, allowing the steel bar to move smoothly to the right within the conveying box. The steel bar pushing assembly automatically pushes the steel bar to the bending processing position. When the steel bar reaches the predetermined position, the hydraulic rods 6 at the left and right ends of the rear side of the fixing block 5 begin to work. The output end of the hydraulic rod 6 penetrates the interior of the steel bar conveying box 3 and drives the C-shaped plate 7 to move. Multiple adjusting rollers 8, equidistantly rotatable inside the C-shaped plate 7, move in tandem with the steel bar when they come into contact with it. The movement and rotation clamp and position the end of the reinforcing bar. The adjusting roller 8 can be adaptively adjusted according to the size of the reinforcing bar to ensure that a stable clamping force can be provided for reinforcing bars of different sizes. After the reinforcing bar is firmly clamped, the rotating disk 9 at the rear right side of the top of the worktable 1 begins to rotate. The working roller 10 in the center of the top wall of the rotating disk 9 and the bending roller 11 on the front side of the top contact the reinforcing bar. The working roller 10, as the main support and positioning component, provides a reference point for bending the reinforcing bar. The bending roller 11, driven by the rotating disk 9, applies bending force to the reinforcing bar, causing the reinforcing bar to bend according to a predetermined angle and shape.

[0047] Furthermore, the operator places the steel bars to be processed inside the steel bar conveying box 3. At this time, the steel bars are in contact with the conveying rollers 4. The conveying rollers 4 reduce the friction between the steel bars and the conveying box by their own rotation, allowing the steel bars to move relatively smoothly inside the conveying box. After the steel bars are placed in place, the operator holds the handle 202 and presses the pressure plate 201 downwards. As the pressure plate 201 is pressed down, the hexagonal cone head 203 at its bottom accurately inserts into the insertion hole 204 opened at the top of the steel bar conveying box 3. The hexagonal cone head 203 continues to move downwards until it is completely embedded in the hexagonal cone groove 205 opened at the top of the conveying rollers 4. Since the size of the hexagonal cone head 203 matches the size of the multiple hexagonal cone grooves 205, when the hexagonal cone head 203 is inserted into the hexagonal cone groove 205, it will affect the rotation of the conveying rollers 4. The limiting mechanism effectively prevents accidental movement of the reinforcing bars during transport and subsequent bending. The hexagonal conical groove 205 on the top of the transport roller 4, with a regular hexagonal groove at the bottom and a hexagonal conical groove at the top, not only provides accurate guidance for the insertion of the hexagonal conical head 203, but also allows the hexagonal conical head 203 to fit tightly, increasing the stability and reliability of the locking. During the bending process of the reinforcing bars, the hydraulic rod 6 drives the C-shaped plate 7 to move, and the adjusting roller 8 clamps and positions the end of the reinforcing bar. At the same time, the rotating disk 9 drives the working roller 10 and the bending roller 11 to apply bending force to the reinforcing bars. Due to the action of the reinforcing bar locking mechanism 2, the reinforcing bars always remain in the predetermined position throughout the bending process without slipping or deviating, thus ensuring the accuracy of the bending angle and shape.
