Guardrail bending equipment is a type of machinery used to bend guardrail panels (commonly found in safety protection facilities in road traffic, railways, and other fields). Its main function is to shape metal guardrail panels into the desired form through a precisely controlled bending process. This equipment is typically suitable for processing steel or aluminum guardrail panels.

[0003] For example, patent CN219335472U discloses a bending machine for processing road guardrail panels. Its features include an installation platform, a bending assembly mounted on the installation platform for bending guardrail panel raw materials, a material stop assembly mounted on the bending assembly to prevent the guardrail panel raw materials from shifting during bending, and a cleaning assembly mounted on the bending assembly.

The connecting rod is slidably connected inside the bending assembly, and multiple cleaning pipes are fixedly connected to the bottom end of the connecting rod. A motor is fixedly installed at both the left and right ends of the connecting rod. Therefore, compared with existing technologies, this bending machine for processing road guardrail panels can clean the mold and scrape off material residue adhering to the mold.

[0004] However, the bending machine for processing road guardrail panels according to this application cannot position and rotate the guardrail panels inside the bending machine, making it difficult to meet processing requirements when the guardrail panels need to be bent in multiple directions. Utility Model Content

[0005] The purpose of this utility model is to provide a guardrail bending device to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a guardrail bending device, including an upper base, a side frame fixedly connected to the lower end of the upper base, a lower base installed on the inner end of the side frame, a positioning platform fixedly connected to the surface side of the lower base, an adjusting ruler slidably connected inside the positioning platform, a lifting groove opened inside the lower base, an electric telescopic rod installed at the bottom of the lifting groove, a lifting platform fixedly connected to the top of the electric telescopic rod, a turntable seat rotatably connected to the upper end of the lifting platform, a material conveying groove opened inside the lower base and on both sides of the lifting groove, a material conveying seat slidably connected inside the material conveying groove, a plurality of suction cup seats installed at the top of the material conveying seat, a guardrail plate provided on the surface of the suction cup seats, a front pressure platform slidably connected to the rear end of the upper base, a rotating seat rotatably connected to the rear end of the side frame, and a bending table installed at the front end of the rotating seat.

[0007] According to the above technical solution, a motor platform is fixedly connected to the surface of the lifting platform, and a turntable base is installed on the upper end of the motor platform.

[0008] According to the above technical solution, the upper end of the positioning platform is threadedly connected to a limit screw.

[0009] According to the above technical solution, an electric lead screw is rotatably connected inside the material conveying trough, and a material conveying seat is threadedly connected to the surface of the electric lead screw.

[0010] According to the above technical solution, a second hydraulic rod is fixedly connected to the top of the upper base, a front pressure platform is fixedly connected to the lower end of the second hydraulic rod, and a trapezoidal pressure seat is fixedly connected to the bottom end of the front pressure platform.

[0011] According to the above technical solution, the rotating seat has an adjustment groove inside, and a first hydraulic rod is fixedly installed inside the adjustment groove. A template seat is fixedly connected to the top of the first hydraulic rod inside the adjustment groove.

[0012] According to the above technical solution, the front end of the template base is threadedly connected to a connecting screw, and a bending table is installed on the front end of the template base through the connecting screw.

[0013] According to the above technical solution, a motor housing is installed on the side end of the side frame.

[0014] Compared with existing technologies, the beneficial effects achieved by this utility model are as follows: In use, the guardrail panel can be placed on the surface of the lower machine base and positioned using an adjusting ruler. Then, the material conveyor is used to transport the guardrail panel to the rear end of the lower machine base for bending. After bending one side of the guardrail panel, it can be returned to the upper position of the lifting slot. The electric telescopic rod is then activated to move the lifting platform upwards. The turntable is used to lift the guardrail panel, and the angle of the guardrail panel is adjusted using the rotating turntable. The guardrail panel is then reset and transported again to the bending point for further processing using the material conveyor. The equipment can be operated in conjunction with a CNC machine tool and a control console. Before placing the guardrail panel, its length and width dimensions can be input at the control console to facilitate calculation of the center point of the guardrail panel using the transport device. Before rotating the guardrail panel, its center position is then transported to the turntable. In practice, the rear end of the guardrail can be placed at the front end of the lower base for alignment. First, use the adjusting rulers on both sides to align it, and then use the pre-entered dimensional data at the control console to control the transport device to move the guardrail.

[0015] When the guardrail panel is sent to the rear end of the lower base for bending, the second hydraulic rod can be used to move the front pressure table and trapezoidal pressure seat downwards, pressing down on the surface of the guardrail panel. After bending, the first hydraulic rod can be activated to move the template seat and bending table towards the rear end of the rotating seat, moving the bending table away from the guardrail panel. Then, the rotating seat is rotated to reset, and the first hydraulic rod is activated again to reset the template seat and bending table. When the bending table is moved away from the guardrail panel and the rotating seat is rotated, the bending table can be seen touching the bent guardrail panel during rotation. The bending table is detachable and can be disassembled and installed before processing using connecting screws. Different sizes of bending tables can be customized or replaced according to production needs. This device is equipped with an auxiliary positioning device, which allows for rotational adjustment of the guardrail panel angle and enables bending processing on multiple sides of the guardrail panel.

The upper base 1 houses the limiting clamping device for installing the guardrail plate 18. The upper base 1 is supported by the side frame 2, the rear end of which is used to install the bending processing device for the guardrail plate 18.

[0024] The lower base 3 is located below the upper base 1 and inside the side frame 2. A device for transporting, positioning, and adjusting the guardrail panel 18 is installed inside the lower base 3. Positioning platforms 19 are installed on both the left and right ends of the lower base 3 surface. When the guardrail panel 18 is placed on the surface of the lower base 3, the side ends of the guardrail panel 18 can be positioned using adjustable rulers 21 on both sides, allowing the center of the guardrail panel 18 to be positioned close to the center of the lower base 3. This allows for quick positioning of guardrail panels 18 of different sizes. Two material conveying seats 16 for transporting the guardrail panel 18 are installed inside the lower base 3. These two material conveying seats 16 can move back and forth inside the lower base 3, using suction cup seats 17 on the surface of the material conveying seats 16 to transport the guardrail panel 18 back and forth. In use, the guardrail panel 18 can be placed on the surface of the lower base 3 and positioned using the adjusting ruler 21. Then, the material conveyor 16 is used to transport the guardrail panel 18 to the rear end of the lower base 3 for bending. After bending one side of the guardrail panel 18, it can be returned to the upper position of the lifting slot 22. The electric telescopic rod 25 is then activated to move the lifting platform 26 upwards. The turntable 23 is used to lift the guardrail panel 18, and the angle of the guardrail panel 18 is adjusted using the rotating turntable 23. The guardrail panel 18 is then reset and transported again to the bending point for further processing using the material conveyor 16. The equipment can be operated in conjunction with a CNC machine tool and a control console. Before placing the guardrail panel 18, its length and width dimensions can be input at the control console to facilitate calculation of the center point of the guardrail panel 18 using the transport device. Before rotating the guardrail panel 18, its center position is sent to the turntable 23. In specific operation, the rear end of the guardrail 18 can be placed at the front end of the lower base 3 for alignment. First, the adjustment rulers 21 on both sides are used for alignment. Then, the transport device is controlled to move the guardrail 18 by using the size data input in advance at the control console.

[0025] Please see Figure 1-3 A motor platform 24 is fixedly connected to the surface of the lifting platform 26, and a turntable seat 23 is installed on the upper end of the motor platform 24. When the motor platform 24 is started, it can drive the turntable seat 23 to rotate. When it affects the adjustment of the guardrail 18 angle, the lifting platform 26 can be used to drive the turntable seat 23 to move upward, so that the guardrail 18 is lifted away from the surface of the lower base 3 before it can be rotated.

[0026] Please see Figure 1-2 The upper end of the positioning table 19 is threadedly connected to a limit screw 20. When adjusting the adjusting ruler 21, the rotating limit screw 20 can be used to limit its movement. When the limit screw 20 is tightened, the limit rod at the lower end of the limit screw 20 can be used to press against the surface of the adjusting ruler 21.

[0027] Please see Figure 1-4An electric lead screw 15 is rotatably connected inside the material conveying trough 14, and a material conveying seat 16 is threadedly connected to the surface of the electric lead screw 15. The electric lead screw 15 is driven by a motor. When the electric lead screw 15 rotates, it can drive the material conveying seat 16 inside the material conveying trough 14 to move back and forth. The guardrail 18 can be transported back and forth through the material conveying seat 16 and the suction cup seat 17.

[0028] Please see Figure 1-4 A second hydraulic rod 12 is fixedly connected to the top of the upper base 1. A front pressure table 5 is fixedly connected to the lower end of the second hydraulic rod 12. A trapezoidal pressure seat 13 is fixedly connected to the bottom end of the front pressure table 5. When the guardrail plate 18 is sent to the rear end of the lower base 3 for bending, the second hydraulic rod 12 can be used to drive the front pressure table 5 and the trapezoidal pressure seat 13 to move downwards, and the trapezoidal pressure seat 13 presses down on the surface of the guardrail plate 18.

[0029] Please see Figure 1 The rotating seat 6 has an adjustment groove 7 inside, and a first hydraulic rod 8 is fixedly installed inside the adjustment groove 7. A template seat 9 is fixedly connected to the top of the first hydraulic rod 8 inside the adjustment groove 7. When the rotating seat 6 rotates, it can drive the template seat 9 to rotate, and finally drive the bending table 11 to rotate, which can bend the guardrail panel 18. After the bending process is completed, the first hydraulic rod 8 can be activated to move the template seat 9 and the bending table 11 to the rear end of the rotating seat 6, so that the bending table 11 is away from the side of the guardrail panel 18. Then the rotating seat 6 is rotated to reset, and the first hydraulic rod 8 is activated again to reset the template seat 9 and the bending table 11. When the bending table 11 is away from the guardrail panel 18 and the rotating seat 6 is rotated again, it can be seen that the bending table 11 touches the bent guardrail panel 18 during rotation.
