Description

Technical Field

[0001] This utility model relates to the field of steel bar processing in construction, specifically to a high-efficiency steel bar bending machine for building construction. Background Technology

[0002] With the continuous development of construction engineering, steel bars, as the skeleton of concrete, constitute reinforced concrete and have become the main material widely used and in large quantities in building structures. Steel bar bending machines play an important role in the steel bar processing process during construction, but they also have some drawbacks. For example, existing steel bar bending machines require a large degree of manual assistance, and bending is mostly done manually by hand. Since steel bars are generally strong, hand-held bending machines affect work efficiency and thus construction progress. Moreover, the bending angle is not precise enough, resulting in substandard quality of the bent steel bar products, which affects subsequent use.

[0003] Chinese Patent Publication No. CN219074202U discloses a rebar bending machine, including a machine platform and a turntable mounted on the machine platform. A central rotating shaft is located in the center of the turntable, and a bending pin is eccentrically mounted on the turntable. The turntable is driven to rotate horizontally by a rotating drive device. The machine platform also includes a limiting block, a fixing frame, and a support assembly for limiting the rebar. At least one roller is mounted on the fixing frame. The limiting block has a limiting portion for the side of the rebar to abut against, and the limiting portion is eccentrically mounted relative to the central rotating shaft. The limiting portion is located between the bending pin and the roller, forming a gap for rebar insertion between the limiting portion and the central rotating shaft. This design and coordination of the turntable, central rotating shaft, bending pin, limiting block, fixing frame, and support assembly ensures that the limiting block and roller are in close contact with the rebar, thus fixing it in place. The rotation of the turntable causes the central rotating shaft and bending pin to cooperate in bending the rebar, making bending quick and convenient.

[0004] However, existing rebar bending machines are still not efficient enough in use. They usually cannot bend multiple rebars at the same time, nor can they clamp and adjust rebars of different sizes accordingly. If multiple rebars are forced to bend at the same time, the stability and safety of the operation cannot be guaranteed. In addition, existing rebar bending machines still require manual intervention for most of the auxiliary material feeding work, which reduces the efficiency of rebar processing and increases the input of labor costs. Utility Model Content

[0005] To address the aforementioned issues, a high-efficiency rebar bending machine for building construction is provided. By adding adjustable clamping components, protective structures, and pushing components, the machine solves problems such as insufficient efficiency, poor safety, and excessive manual assistance required for rebar bending.

[0006] To address the problems of existing technologies, this utility model provides a high-efficiency steel bar bending machine for building construction, comprising a housing and a working panel. The working panel is located at the opening of the housing. It also includes a clamping assembly for clamping and fixing the steel bars to be bent. The clamping assembly includes two semi-circular clamping columns, symmetrically installed in the housing, facing each other with one side of their planes opposite each other. The clamping assembly also includes a protective structure located on the top of the semi-circular clamping columns. The protective structure includes a rotating screw sleeve rotatably connected to the top of one of the semi-circular clamping columns. An adjusting screw is fitted onto the inner wall of the rotating screw sleeve, with the thread on the surface of the adjusting screw matching the thread on the inner wall of the rotating screw sleeve. One end of the adjusting screw is threadedly connected to an adjusting buckle. A limiting rod is provided on the top of the other semi-circular clamping column, matching the adjusting buckle.

[0007] Preferably, a sliding base is fixed to the bottom of the semi-circular clamping column, and several cylindrical rollers are installed on both sides of the sliding base. A propulsion cylinder is installed on one side of the sliding base to control the two sliding bases to move closer to each other or further apart.

[0008] Preferably, the high-efficiency rebar bending machine also includes a pushing component to assist the rebar in feeding into the clamping component. The pushing component includes two symmetrical feeding rollers, which are mounted on a working panel on one side of the clamping component. The surface of the feeding rollers is fitted with flexible wheel rims.

[0009] Preferably, the pushing assembly further includes an end-effector for pushing the end of the rebar. The end-effector is installed on the side of the feed roller away from the clamping assembly and includes a pusher for driving the movement of the end-effector. A tilting rod is rotatably connected to the top of the pusher. The tilting rod can rotate at an angle of 0°-90°. A servo motor is also installed behind the surface of the pusher. A brake rod is installed on the output shaft of the servo motor. The brake rod is used to provide rotational drive for the tilting rod.

[0010] Preferably, the high-efficiency rebar bending machine also includes a bending assembly for providing the power required to bend the rebar. The bending assembly includes a bending motor and a main turntable. The bending motor meshes with the tooth grooves of the main turntable around one circumference through a gear mounted on its output shaft. A bending column is fixed on the top of the main turntable, and a contact roller is sleeved on the bending column. The contact roller is used to make direct contact with the rebar.

[0011] Preferably, the working panel has an adjustment groove in the middle for placing a semi-circular clamping column, an arc-shaped groove on one side for placing a bending column, and an end groove on the other side for placing a flipping rod.

[0012] The advantages of this utility model compared to the prior art are:

[0013] 1. This utility model head achieves the effect of bending multiple steel bars simultaneously by adding two semi-circular clamping columns with adjustable spacing and installing a protective structure on the semi-circular clamping columns. The protective structure ensures that multiple steel bars are bent stably and safely. In addition, it can also provide limit protection when steel bars are fed, reduce the control range of steel bars popping out and detaching from the clamping components, improve the safety and continuity of the steel bar bending device, and protect the personal safety of the operator.

[0014] 2. This utility model adds a pushing component, which uses the rotation of the feeding wheel to push the steel bars to move continuously towards the clamping component. It can provide a stable feeding auxiliary component, help multiple steel bars to be fed stably at the same time, reduce manual intervention, save labor costs, and improve feeding efficiency.

[0015] 3. By adding an end-effector, this utility model pushes the end of the steel bar to the set bending position by pushing the tilting rod with a pusher, which can provide stable feeding and pushing for the end of the steel bar. This allows the device to save manpower to the maximum extent, further protect the safety of operators, and improve the intelligence level of the device. Attached Figure Description

[0025] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figures 1-8 As shown, a high-efficiency rebar bending machine for building construction includes a housing 1 and a work panel 2. The work panel 2 is located at the opening of the housing 1. It also includes a clamping assembly 3 for clamping and fixing the rebar to be bent. The clamping assembly 3 includes two semi-circular clamping columns 31, symmetrically installed in the housing 1, with the two semi-circular clamping columns 31 facing each other on one side of their planes. The clamping assembly 3 also includes a protective structure 35. The protective structure 35 is located at... The top of the semi-circular clamping column 31 has a protective structure 35 including a rotating screw sleeve 351. The rotating screw sleeve 351 is rotatably connected to the top of one of the semi-circular clamping columns 31. An adjusting screw 352 is sleeved on the inner wall of the rotating screw sleeve 351. The thread on the surface of the adjusting screw 352 is adapted to the thread on the inner wall of the rotating screw sleeve 351. One end of the adjusting screw 352 is threadedly connected to an adjusting buckle 353. The top of the other semi-circular clamping column 31 is provided with a limiting rod 354, which is adapted to the adjusting buckle 353.

[0027] During operation, the device clamps and fixes the steel bars to be bent using semi-circular clamping posts 31. To bend the steel bars more efficiently, the device can clamp multiple steel bars simultaneously and perform bending operations at the same time. To prevent the steel bars from popping out during the simultaneous bending of multiple steel bars, a protective structure 35 is provided on the clamping assembly 3. The protective structure 35 can quickly lock the clamped steel bars. Specifically, the adjusting screw 352 and adjusting buckle 353 on one semi-circular clamping post 31 are rotated so that the adjusting buckle 353 is positioned to fit the limiting rod 354 on the other semi-circular clamping post 31. The screw sleeve 351 is then rotated so that the adjusting screw 352 drives the adjusting buckle 353 to engage with the limiting rod 354. The adjusting buckle 353 and adjusting screw 352 provide a quick protective structure 35 for the top of the two semi-circular clamping posts 31, limiting the possible popping and jumping of the steel bars during the bending process. The protective structure 35 can also provide a limiting function during subsequent steel bar feeding, so that the steel bar will not come out of the clamping range of the semi-circular clamp 31 during feeding.

[0028] like Figures 4-6 As shown, a sliding base 32 is fixed to the bottom of the semi-circular clamping column 31. Several cylindrical rollers 33 are installed on both sides of the sliding base 32. A propulsion cylinder 34 is installed on one side of the sliding base 32 to control the two sliding bases 32 to move closer to each other or further apart.

[0029] This structure can push the two sliding bases 32 and the semi-circular clamping column 31 closer or further apart by the action of the propulsion cylinder 34. This can provide necessary convenience when placing steel bars, and can also adjust the distance between the two semi-circular clamping columns 31 according to the diameter of different steel bars, so as to ensure a more fitting clamping effect on the steel bars to be bent.

[0030] like Figures 1-3 As shown, the high-efficiency rebar bending machine also includes a pushing component 4, which is used to assist the rebar in feeding into the clamping component 3. The pushing component 4 includes two symmetrical feeding rollers 41. The feeding rollers 41 are installed on the working panel 2 on one side of the clamping component 3, and the surface of the feeding rollers 41 is fitted with flexible wheel rings 42.

[0031] During feeding, the reinforcing bar is passed through the gap between two feeding rollers 41. The rotation of the feeding rollers 41 feeds the reinforcing bar towards the semi-circular clamping column 31, requiring minimal manual assistance and improving feeding efficiency when bending the reinforcing bar. The bottom of each feeding roller 41 is directly driven by a set of motors, and the two symmetrical feeding rollers 41 rotate in opposite directions. A flexible rim 42 is attached to the surface of each feeding roller 41. The flexible rim 42 is preferably made of rubber, which has good elasticity and cushioning properties, effectively reducing the impact and noise generated during the movement or vibration of the reinforcing bar. It acts as a buffer and vibration damper between the reinforcing bars, protecting them from damage. Alternatively, fiber-reinforced composite materials and carbon fiber cloth can be used, both of which have strong cushioning and support properties, as well as a certain degree of elasticity, facilitating the passage of different reinforcing bars between the two feeding rollers 41. Simultaneously, they increase the friction between the reinforcing bar and the roller, making it easier for the feeding rollers 41 to push the reinforcing bar through the feeding operation.

[0032] like Figure 7 As shown, the pushing assembly 4 also includes an end auxiliary device 43 for pushing the end of the rebar. The end auxiliary device 43 is installed on the side of the feeding wheel 41 away from the clamping assembly 3 and includes a pusher 431 for driving the movement of the end auxiliary device 43. A flipping rod 432 is rotatably connected to the top of the pusher 431. The flipping rod 432 can rotate at an angle of 0°-90°. A servo motor 433 is also installed behind the surface of the pusher 431. A brake rod 434 is installed on the output shaft of the servo motor 433. The brake rod 434 is used to provide rotational drive for the flipping rod 432.

[0033] When the steel bar is fed to the end, the auxiliary feeding function of the feeding wheel 41 is reduced. At this time, the end auxiliary device 43 can be activated. First, the servo motor 433 is activated, and the brake lever 434 is rotated by the servo motor 433. The brake lever 434 pushes the flipping lever 432 from parallel to the working panel 2 to perpendicular to the working panel 2, and also perpendicular to the end face of the steel bar. Then, the pusher 431 is activated to push the entire end auxiliary device 43 forward. During the process, the flipping lever 432 will push the end of the steel bar to continue moving towards the clamping assembly 3 until the end of the steel bar enters the designated bending position.

[0034] like Figures 3-5 As shown, the high-efficiency rebar bending machine also includes a bending assembly 5, which provides the power required for bending rebar. The bending assembly 5 includes a bending motor 51 and a main turntable 52. The bending motor 51 meshes with the tooth groove of the main turntable 52 around the turntable through a gear mounted on its output shaft. A bending column 53 is fixed on the top of the main turntable 52, and a contact roller 54 is sleeved on the bending column 53. The contact roller 54 is used to directly contact the rebar.

[0035] The bending motor 51 drives the main turntable 52 to rotate, enabling the bending column 53 and contact roller 54 to bend the reinforcing bar on the semi-circular clamping column 31. The contact roller 54 is movably connected to the bending column 53, facilitating the replacement of the contact roller 54 and enabling bending of reinforcing bars of different diameters and shapes. It also facilitates regular maintenance and replacement of the contact roller 54, further protecting the bending column 53 from damage and extending the service life of the main structure of the device.

[0036] like Figure 8 As shown, the working panel 2 has an adjustment groove 21 in the middle of its surface for placing a semi-circular clamping column 31. An arc-shaped groove 22 is provided on one side of the adjustment groove 21 for placing a bending column 53. An end groove 23 is provided on the other side of the adjustment groove 21 for placing a flipping rod 432.

[0037] The adjusting groove 21 can accommodate two semi-circular clamping columns 31 to adjust the distance between them, making it easier to clamp more types and sizes of steel bars; the arc groove 22 makes the bending column 53 maintain a more stable path when rotating; the end groove 23 makes the flipping rod 432 remain parallel to the working panel 2 when not in operation, without affecting the normal feeding operation of steel bars.

[0038] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
