Moreover, the described specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0028] Referring to Figures 1 to 5The application provides an automatic bending device, which comprises a feeding mechanism 100, a cutting mechanism 200 connected with the feeding mechanism 100, a bending mechanism 300 connected with the cutting mechanism 200 through a first conveying mechanism 400, a material collecting mechanism 500 connected with the cutting mechanism 200 through a second conveying mechanism 600 and a control mechanism comprising a controller 700 connected with the feeding mechanism 100, the cutting mechanism 200, the bending mechanism 300 and the material collecting mechanism 500.

[0029] The automatic bending device can simultaneously realize cutting and bending of the support 110, avoids surface abrasion and pollution of the support 110 during transfer, does not need manual operation, reduces labor intensity, guarantees safety of workers and improves work efficiency.

[0030] The bending mechanism 300 is provided with a timer connected with the punch 330 and the controller 700. Specifically, when the punch 330 is lowered to cooperate with the die 320 to bend the support 110, the timer starts timing, and when the timer reaches the set time, the punch 330 is raised to move away from the die 320. Through the above structure, the cooperation time of the punch 330 and the die 320 can be prolonged, so as to ensure the stability of the bending size of the support 110 and improve the product quality.

[0031] Reference Figure 1 and Figure 2Further, the base 310 is provided with a first trigger switch 360 for sensing the rising height of the male die 330, the first trigger switch 360 being connected with the air nozzle 340 and the controller 700 respectively, when the male die 330 reaches the height corresponding to the first trigger switch 360, the material ejection pin 350 is just away from the bottom of the bracket 110. Specifically, after the bracket 110 is bent after the cooperation of the male die 330 and the female die 320, the male die 330 rises to be away from the female die 320, when the male die 330 rises to the height corresponding to the first trigger switch 360, at this time the first trigger switch 360 is triggered, then the air nozzle 340 works to blow the bracket 110 into the second conveying mechanism 600, so as to realize the output of the bracket 110. Since the male die 330 rises to the height corresponding to the first trigger switch 360, the material ejection pin 350 is just away from the bottom of the bracket 110 at this time, the material ejection pin 350 has the function of keeping the direction, so as to avoid the bracket 110 from being stuck due to the deviation in the blowing process, thereby ensuring the stability of the work. The air nozzle 340 is arranged at the end of the first conveying mechanism 400, at this time the direction of the air nozzle 340 is consistent with the output direction of the bracket 110, which is convenient for the installation of the air nozzle 340 and can ensure the smooth blowing of the bracket 110 out of the female die 320.

[0032] Referring to Figures 1 to 3 In some embodiments of the present application, the control mechanism further comprises an alarm 710, the feeding end of the second conveying mechanism 600 is provided with a second trigger switch 610, the second trigger switch 610 being connected with the alarm 710 and the controller 700 respectively. Specifically, when the bracket 110 enters the second conveying mechanism 600 and passes through the second trigger switch 610, the second trigger switch 610 is triggered, at this time it is indicated that the bending mechanism 300 can normally eject material, then the alarm 710 does not work, and the bracket 110 continues to be conveyed under the action of the second conveying mechanism 600; if the bending is completed, but no bracket 110 enters the second conveying mechanism 600 and passes through the second trigger switch 610, the second trigger switch 610 is not triggered, at this time it is indicated that the bending mechanism 300 fails to eject material, then the alarm 710 works, and all mechanisms stop working to wait for the staff to handle, and after the staff handle, all mechanisms start working again. Through the above structure, the detection and prompt of work abnormality can be realized, and the stability and safety of the smooth work can be ensured. The alarm 710 is arranged as an audible and visual alarm 710, so as to simultaneously perform sound prompt and light prompt, thereby improving the stability and safety.

[0033] It is conceivable that the discharge end of the second conveying mechanism 600 is provided with a third trigger switch 620, which is connected with the material collecting mechanism 500 and the controller 700 respectively. Specifically, when the support 110 reaches the third trigger switch 620, the third trigger switch 620 is triggered to drive the material collecting mechanism 500 to work for a delay time, so that the support 110 can also have time to enter the material collecting mechanism 500, and then the material collecting mechanism 500 works to realize the material collection of the support 110. Wherein, the material collecting mechanism 500 comprises a material receiving plate 510 and a material pushing block 520, the material receiving plate 510 is provided with a material receiving area 530 and a material collecting area 540, the material receiving area 530 is located at the end of the second conveying mechanism 600, the material collecting area 540 is arranged at one side of the material receiving area 530, and the material pushing block 520 is arranged at the side of the material receiving area 530 away from the material collecting area 540, and the material pushing block 520 is used to push the support 110 from the material receiving area 530 to the material collecting area 540. The support 110 enters the material collecting mechanism 500 and falls into the material receiving area 530, at this time the material pushing block 520 moves to push the support 110 from the material receiving area 530 to the material collecting area 540, so as to empty the material receiving area 530 to facilitate the material collection of the next support 110. In the embodiment, the material pushing block 520 is connected with a pneumatic cylinder, and the pneumatic cylinder drives the material pushing block 520 to move, so that the structure is simple and the work is stable.

[0034] With reference to Figure 1 , Figure 2 and Figure 4 , in some embodiments of the present application, the first conveying mechanism 400 is provided with a fourth trigger switch 410, which is arranged at the output end of the first conveying mechanism 400, and the fourth trigger switch 410 is connected with the air nozzle 340 and the controller 700 respectively. Specifically, when the blank reaches the fourth trigger switch 410 along the first conveying mechanism 400, the fourth trigger switch 410 is triggered to drive the air nozzle 340 to start the delay blowing, at this time the blank can enter the bending mechanism 300, and then the air nozzle 340 works to blow the bending mechanism 300 to remove the impurities on the blank, so as to ensure the product quality.

[0035] It is conceived that the first conveying mechanism 400 is provided with a fifth trigger switch 420, which is connected with the cutting-off mechanism 200 and the controller 700 respectively. When the blank reaches the fifth trigger switch 420, the fifth trigger switch 420 is triggered to drive the cutting-off mechanism 200 to stop working until the blank leaves the fifth trigger switch 420, and then the cutting-off mechanism 200 resumes working, thereby avoiding the accumulation of blanks and affecting production, and ensuring the continuity and stability of the work. Further, the first conveying mechanism 400 is provided with a sixth trigger switch 430, which is arranged on the side of the fifth trigger switch 420 close to the bending mechanism 300, and the sixth trigger switch 430 is connected with the fifth trigger switch 420 and the controller 700 respectively. When the blank leaves the fifth trigger switch 420 and reaches the sixth trigger switch 430, the sixth trigger switch 430 is triggered at this time, and then the fifth trigger switch 420 is also triggered, and at this time the cutting-off mechanism 200 stops working, and the next blank also reaches the fifth trigger switch 420, thereby improving the work efficiency and ensuring the stability and reliability of the work.

[0036] It is easy to understand that the first conveying mechanism 400 is provided with a leveling assembly 440 for leveling the blank, and the fifth trigger switch 420 is arranged behind the leveling assembly 440. By arranging the leveling assembly 440, the blank can be leveled before bending, thereby improving the product quality.

[0037] Referring to Figure 5 In some embodiments of the present application, the feeding mechanism 100 includes a support 110 and a conveying assembly, the conveying assembly including a first conveying wheel 120 and a second conveying wheel 130, the first conveying wheel 120 and the second conveying wheel 130 being rotatably arranged on the support 110, and the first conveying wheel 120 and the second conveying wheel 130 cooperating to clamp and convey the material. The first conveying wheel 120 and the second conveying wheel 130 cooperate to clamp and convey the material to the cutting-off mechanism 200 for cutting, which is simple in structure and easy to operate. Further, the feeding mechanism 100 further includes a guide frame 140 arranged at the front end of the support 110, and the guide frame 140 is rotatably provided with a guide roller 150 supporting the material. By arranging the guide frame 140, the material can be guided and supported to some extent, avoiding scratching the material and ensuring the product quality; at the same time, by rotatably arranging the guide roller 150 on the guide frame 140, the material and the guide frame 140 are rolled and rubbed, further improving the product quality.

[0038] The working process of the automatic bending device is as follows: the feeding mechanism 100 inputs the material and sends it to the cutting mechanism 200, the material is cut into a blank meeting the production requirements by the cutting mechanism 200; then the blank is transported by the first conveying mechanism 400, and is leveled by the leveling assembly 440; when the blank is transported to the sixth trigger switch 430, the next blank is also transported to the fifth trigger switch 420 at this time, the cutting mechanism 200 pauses at this time, and resumes work after the next blank leaves the fifth trigger switch 420; when the blank passes through the fourth trigger switch 410 and enters the bending mechanism 300, the air nozzle 340 works at this time to blow away the impurities on the blank; then the bending mechanism 300 works, the convex die 330 descends to cooperate with the concave die 320 to bend the blank into the bracket 110; then the convex die 330 rises to move away from the concave die 320, when the convex die 330 rises and reaches the height corresponding to the first trigger switch 360, the material ejection needle 350 just leaves the bottom of the bracket 110, at this time the air nozzle 340 works to blow the bracket 110 out of the bending mechanism 300 and into the second conveying mechanism 600; when the bracket 110 passes through the second trigger switch 610, it means that the bending mechanism 300 can normally eject material, and the alarm 710 does not work; the second conveying mechanism 600 continues to convey the bracket 110, when the bracket 110 passes through the third trigger switch 620 and enters the material collecting mechanism 500, the material collecting mechanism 500 works at this time to collect the bracket 110. After the bending mechanism 300 completes the work, but no bracket 110 passes through the second trigger switch 610, it means that the bending mechanism 300 fails to eject material, at this time the alarm 710 works to prompt, and all mechanisms stop working to wait for the worker to handle, and after the worker handles it, all mechanisms start working again.

[0039] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the purpose of the present application.
