Since the connection between the push block 19 and the inner backrest 06 is stable and easy to disassemble, when the push block 19 needs to be replaced or repaired, it can be completed quickly and efficiently, greatly reducing maintenance costs and time costs.

[0025] The worm gear 05 is provided with a product positioning block 08. Through precise design dimensions and positions, the product positioning block 08 helps the worm gear 05 achieve accurate positioning inside the machine.

The product positioning block 08 and the push block 19 are provided with grooves, and the groove positions correspond to each other. Such a design can ensure the precise docking between the worm gear 05 and the push block 19, thereby further improving the operating efficiency and stability of the entire mechanical system. When the machine is running, this precise docking can reduce friction and vibration, extend the service life, and also improve work efficiency and product quality.

[0026] Above the workbench 1, there is a cylinder 11. To ensure the stability and reliability of the cylinder 11, a cylinder fixing seat 12 is arranged vertically below the cylinder 11. This fixing seat not only provides a solid foundation for the cylinder 11 but also ensures the precise position of the cylinder 11 during operation. Below the cylinder fixing seat 12, there is a cylinder piston rod 23, and a product hook 22 is located on the cylinder piston rod 23, which can precisely grasp the lining strip.

[0027] The outer roller 09 is fixed to the worm gear 05 through the lower outer roller fixing block 10, and the outer roller fixing block 10 closely adheres to the worm gear 05. Such a design not only enhances the connection strength between the outer roller 09 and the worm gear 05 but also improves the stability and reliability of the entire system. When the machine is running, even in the face of high-intensity friction and vibration, the outer roller fixing block 10 can ensure the stable connection between the outer roller 09 and the worm gear 05 without loosening or falling off.

[0028] The workbench 1 is composed of a bottom plate one 01 and a bottom plate two 02. The bottom plate one 01 and the bottom plate two 02 are assembled symmetrically, and symmetric worm gears 03 and corresponding structures on the worm gears are respectively provided on the two bottom plates.

[0029] The workbench 1 is fixedly connected through a bottom plate connection block 15. The bottom plate connection block 15 is located on both sides of the reducer 13. To ensure the stable position of the workbench 1 during machine operation, positioning connection blocks 16 are also provided on both sides of the workbench 1. These positioning connection blocks 16 work together with the bottom plate connection block 15 to form a stable support structure, effectively avoiding performance degradation or safety hazards caused by the displacement or inclination of the workbench 1.

[0030] Below the speed reducer 13, there is an electric control box 20. Both ends of the electric control box 20 are fixed to the sides of the first base plate 01 and the second base plate 02. This fixing method not only ensures the stable placement of the electric control box 20, effectively avoiding displacement or damage caused by vibration or external impact, but also enhances the overall structural stability of the system, thereby further ensuring the efficient and safe operation of the entire mechanical system.

[0031] The utility model discloses a special bending device, and the specific working principle and process are as follows:

[0032] Stably move the special product bending device to the designated position in the production workshop, which is the basis for ensuring the smooth progress of subsequent work. After selecting the position, use appropriate tools and equipment to fix the special machine firmly to ensure its stability and immobility.

[0033] Connect the air source to the air cylinder 11. The air source is the key for the air cylinder to work properly. Therefore, it is necessary to ensure that the air source connection is firm, without leakage, and the air pressure is stable. In this way, when the air cylinder needs to act, it can respond quickly and accurately.

[0034] To ensure the stability and reliability of the air cylinder 11, the air cylinder fixing seat 12 is arranged vertically below the air cylinder 11. This fixing seat not only provides a solid foundation for the air cylinder 11, but also ensures the accurate position of the air cylinder 11 during operation. Below the air cylinder fixing seat 12, there is an air cylinder piston rod 23, and the product hook 22 is located on the air cylinder piston rod 23, which can accurately grasp the lining strip. Through such a design, the entire system can complete tasks efficiently and accurately, thereby greatly improving work efficiency and automation. At the same time, such a design also ensures the safety and stability of the product during processing.

[0035] Connect the speed reducer 13 to the power supply. The operation of the speed reducer 13 requires the drive of electric energy. Therefore, it is necessary to ensure that the power supply connection is correct and the voltage is stable. After connecting the power supply, we also need to check the operation status of the speed reducer to ensure its normal operation.

[0036] There are base plate connection blocks 15 on both sides of the speed reducer 13. To ensure the stable position of the workbench 1 during the operation of the machine, there are also positioning connection blocks 16 on both sides of the workbench 1. These positioning connection blocks 16 work together with the base plate connection blocks 15 to form a stable support structure, effectively avoiding performance degradation or safety hazards caused by the displacement or inclination of the workbench 1. This design not only enhances the overall stability of the mechanical system, but also improves the service life and safety of the machine, providing users with more reliable and efficient mechanical equipment.

[0037] After the preparation work is completed, start the operation of the special machine. First, pass the lining strip through one end of the product and accurately place it inside the hollow of the product to provide support and protection during the product bending process. Then, place the product in the grooves of the product positioning block 08 and the pushing block 19 of the special machine to ensure that the product is placed stably and in the correct position.

[0038] The product positioning block 08, through its precise design dimensions and positions, helps the worm gear 05 achieve accurate positioning inside the machine. This positioning not only ensures the smooth operation of the worm gear but also avoids performance degradation or failures caused by position deviations; the product positioning block 08 and the pushing block 19 are provided with grooves, and the groove positions correspond to each other. Such a design can ensure the precise docking between the worm gear 05 and the pushing block 19, thereby further improving the operating efficiency and stability of the entire mechanical system. When the machine is running, this precise docking can reduce friction and vibration, extend the service life, and also improve the work efficiency and product quality.

[0039] Press down the handle of the quick clamp 18 to tightly press the pushing block 19 upward through the quick clamp 18, thereby fixing the product. The clamping force of the clamp should be moderate, ensuring that the product does not move while avoiding damage to the product. Then, operate the connecting rod 07 to rotate it downward, and the opening part of the connecting rod 07 is clamped with the central axis of the outer roller 09 to lock the product and ensure its stability during the bending process.

[0040] The upper end of the quick clamp 18 is connected to the pushing block 19 and is closely connected to the pushing block 19. This connection method ensures the close cooperation and efficient collaboration between the two; the pushing block 19 abuts against one end of the inner backrest 06, not only ensuring the precise position of the docking between the pushing block 19 and the inner backrest 06 but also greatly enhancing the stability between the two. Even when the machine is running at high speed or is subjected to strong vibrations, it can ensure the stability and reliability of the mechanical structure, providing a solid guarantee for the stable operation of the entire system. In addition, this design also takes into account the convenience of maintenance and replacement. Since the pushing block 19 is easy to disassemble, when it is necessary to replace or repair the pushing block 19, it can be completed quickly and efficiently, greatly reducing the maintenance cost and time cost.

[0041] Press the start button, the worm 03 is driven by the reducer 13, the worm 03 drives the worm wheel 05 to rotate, the inner backing 06 on the worm wheel 05 rotates accordingly, and the outer roller 09 also rotates simultaneously. When the part of the inner backing 06 with a circular right angle rotates with the worm wheel 05, it will squeeze the product together with the outer roller 09, and the product is bent according to the circular right angle shape of the inner backing 06. While the product is being bent, the hole of the inner lining strip of the product will be hooked on the product hook 22, and the cylinder 11 moves upward to pull out the lining strip, that is, the entire bending action is completed. With this structural design, the reducer 13 is directly used as the power transmission component, and the internal components of the special machine can be adjusted relatively to complete the work. The structure is simple and convenient, the overall development cost is low, the occupied space is relatively small, it is flexible to move, and it is convenient to use and place.
