[0033] Function description of the main structural components of this solution:

[0034] Machine housing 1: As the basic framework of the device, it protects the internal structure and operating components.

[0035] Fixed block 4: Located on one side of the outer front end of the machine housing 1, it is used to install the clamping block 5 to fix the metal wire or sheet material.

[0036] Clamping block 5: Two clamping blocks 5 are installed on the fixed block 4, used to clamp the metal wire or sheet material to be tested.

[0037] Servo motor 6: Set at the front end of the outside of the fixed block 4, by controlling the rotation of the fixed plate 7, the angle adjustment of the exhaust pipe 8 is realized.

[0038] Fixed plate 7: Connects the servo motor 6 and the exhaust pipe 8, and realizes angle adjustment through the drive of the servo motor 6.

[0039] Air inlet pipe 9 and exhaust pipe 8: One end of the air inlet pipe 9 is located outside the fixed plate 7, and is hermetically fixed to the exhaust pipe 8. The airflow generated by the fan 10 enters the exhaust pipe 8 through the air inlet pipe 9 and then is discharged from the other end of the exhaust pipe 8.

[0040] Fan 10: Set inside the air inlet pipe 9, generates airflow, and drives the discharge of debris.

[0041] Display control screen 2 and bending mechanism 3: Respectively used to display device status and control bending operations, and are conventional components of the repeated bending machine.

[0042] Debris cleaning: Start the servo motor 6 to turn the exhaust pipe 8 upwards to a position close to the clamping block 5, and start the fan 10 to generate airflow. Under the action of the Bernoulli principle, a negative pressure is formed on the side of the exhaust pipe 8 close to the clamping block 5, thereby extracting the debris generated during the bending of the metal wire or sheet material.

[0043] Storage net bag 13: Through the magnetic attraction connection of the magnet ring 11 and the iron ring 12, the storage net bag 13 can be conveniently fixed to the end of the exhaust pipe 8. The debris is carried into the storage net bag 13 by the air flow, facilitating subsequent cleaning.

[0044] Brush bristles 16: A drive motor 14 is provided on one side of the upper end of the exhaust pipe 8 close to the clamping block 5. The drive motor 14 drives the fixed rod 15 and the brush bristles 16 to rotate. The brush bristles 16 can further clean the debris around the clamping block 5, improving the cleaning effect.

[0045] Workflow of this solution:

[0046] Preparation work: Clamp the metal wire or sheet to be tested in the clamping block 5, and set the bending parameters through the display control screen 2.

[0047] Start the test: Start the bending mechanism 3 to conduct repeated bending tests.

[0048] Debris cleaning: During or after the test, start the steering gear 6 and the fan 10 to clean the debris. At the same time, the drive motor 14 can be started to further clean the debris around the clamping block 5 by using the brush bristles 16.

[0049] Collect debris: Remove the storage net bag 13 from the exhaust pipe 8, pour out the debris in it, and then refix it to the exhaust pipe 8.

[0050] During use, start the steering gear 6 to make the fixed plate 7 drive the exhaust pipe 8 to turn upward. One end of the exhaust pipe 8 is close to the clamping block 5. Start the fan 10 to generate an air flow. The air flow enters the exhaust pipe 8 obliquely through the air inlet pipe 9. Subsequently, the air flow is discharged from the end of the exhaust pipe 8 away from the clamping block 5. Under the Bernoulli principle, the negative pressure is drawn on the side of the exhaust pipe 8 close to the clamping block 5, thereby discharging the debris remaining after the fracture of the metal wire or sheet. It should be noted that in order to save space and highlight the innovative elements of this patent, this solution is an improvement on the relevant structures of the non-bending mechanism 3 based on the existing repeated bending machine. Some conventional devices such as the display control screen 2, the bending mechanism 3, the steering gear 6, the fan 10, and the drive motor 14 are not described in detail in this patent.

[0051] This solution: Fix the upper end of the metal wire or sheet to the bending mechanism 3, insert the lower end between the clamping blocks 5, control the clamping blocks 5 to clamp and fix the lower end of the metal wire or sheet, start the operation of the bending mechanism 3 through the display control screen 2, and then conduct repeated bending tests on the metal wire or sheet. After the test is completed, take out the metal wire or sheet, start the servo motor 6 so that the fixing plate 7 drives the exhaust duct 8 to turn upward, one end of the exhaust duct 8 is close to the clamping blocks 5, start the fan 10 to generate air flow, the air flow enters the exhaust duct 8 obliquely through the air inlet duct 9, and then the air flow is discharged from the end of the exhaust duct 8 far from the clamping blocks 5. Under the Bernoulli principle, negative pressure air extraction is carried out on the side of the exhaust duct 8 close to the clamping blocks 5, so as to discharge the debris remaining after the fracture of the metal wire or sheet. Start the drive motor 14 to make the fixed rod 15 rotate, and then make the brush bristles 16 clean the inside of the upper end of the clamping blocks 5 to improve the cleaning effect.

[0052] The repeated bending machine provided by this solution effectively solves the problem of debris cleaning generated during the repeated bending test of metal wires or sheets by introducing components such as the fan 10, the exhaust duct 8, the magnet ring 11, the storage mesh bag 13, and the brush bristles 16, improving the cleaning efficiency and operation convenience of the equipment. At the same time, other conventional parts of the equipment, such as the display control screen 2 and the bending mechanism 3, have also been well integrated and optimized, making the entire equipment more perfect and efficient.
