[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a bending device for zinc-aluminum alloy accessories, including: a workbench 2, the top of the workbench 2 is rotatably connected to a rotating seat 16, the top of the rotating seat 16 is fixedly connected to a turntable 5, the top of the turntable 5 is equidistantly fixedly connected to a plurality of lower molds 4, the outer surfaces of the plurality of lower molds 4 are all fixedly connected to infrared receivers 3, the top of the workbench 2 is fixedly connected to a bracket 6 near the rear side, the inner top of the bracket 6 is fixedly connected to an infrared transmitter 13, the inner surfaces of the plurality of lower molds 4 are all symmetrically fixedly connected to telescopic rods 10, the inner surfaces of the plurality of lower molds 4 are all movably connected to top plates 12, the outer surfaces of the plurality of telescopic rods 10 are all sleeved with springs 11, the inner surface of the workbench 2 A motor 15 is fixedly connected to the surface, and the output end of the motor 15 movably penetrates the inner top of the workbench 2. The output end of the motor 15 is fixedly connected to the driving gear 1. The outer surface of the rotating seat 16 is fixedly connected to the driven gear 14. The outer surface of the driven gear 14 is meshed with the outer surface of the driving gear 1. The position of the infrared transmitter 13 matches the positions of the multiple infrared receivers 3. The top of the bracket 6 is fixedly connected to the hydraulic rod 9, and the driving end of the hydraulic rod 9 movably penetrates the top of the bracket 6. The tops of the multiple telescopic rods 10 are respectively fixedly connected to the bottoms of the multiple top plates 12, and the driving end of the hydraulic rod 9 is fixedly connected to the upper mold 7. The position of the lower mold 4 matches the positions of the multiple upper molds 7.

[0023] The effect achieved by the entire embodiment 1 is that the electrical components on the bending device are electrically connected by a PLC controller. When the zinc-aluminum alloy accessories are bent, the material to be processed is placed on the lower mold 4, and then the motor 15 is started to drive the driving gear 1 to rotate. The driving gear 1 is meshed with the driven gear 14, so that the driving gear 1 will drive the driven gear 14 to rotate when it rotates, thereby driving the rotating seat 16 to rotate, and the turntable 5 is rotated. When the turntable 5 is rotating, the infrared transmitter 13 will always emit an infrared light signal downward. When the turntable 5 rotates to a certain extent, the infrared light signal emitted by the infrared transmitter 13 will be received by the infrared receiver 3 and converted into an electrical signal, and then transmitted to the controller. The controller receives and processes the electrical signal of the infrared receiver 3, and then controls the motor 15 to stop rotating, so that the turntable 5 stops rotating, so that the corresponding lower mold 4 stops accurately above the upper mold 7, and then starts the hydraulic rod 9 to move its driving end downward. The upper mold 7 is driven to move downward, so that the lower mold 4 and the upper mold 7 are used in conjunction with each other to bend the material to be processed. During bending, the upper mold 7 will simultaneously apply downward pressure to the top plate 12 when bending the material, so that the spring 11 and the telescopic rod 10 are compressed. When the bending is completed, the hydraulic rod 9 is started to move the upper mold 7 upward, and then the motor 15 is started again to rotate, and with the cooperation of the infrared transmitter 13 and the infrared receiver 3, the material on the other lower mold 4 is bent. At the same time, during the bending work, the lower mold 4 after the material is bent will rotate to the outside. At this time, the top plate 12 is no longer subjected to the pressure of the upper mold 7, so that the top plate 12 will be driven to move upward under the action of the rebound force of the spring 11, and the formed accessories will be pushed out of the lower mold 4, so that it is convenient for the staff to take out and replace the new material to be processed. After a lower mold 4 completes stamping, the turntable 5 can be rotated to move the next lower mold 4 to the stamping position, thereby realizing continuous stamping, which greatly improves the production efficiency.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, guide rods 8 are symmetrically and movably penetrated through the top of the bracket 6 , and the bottoms of the two guide rods 8 are fixedly connected to the top of the upper mold 7 .

[0025] The effect achieved by the entire embodiment 2 is that when the upper mold 7 moves downward, the two guide rods 8 will slide along the bracket 6 to limit the moving path of the upper mold 7, ensure the moving direction of the upper mold 7, and ensure subsequent stamping work.

[0026] Working principle: When bending zinc-aluminum alloy accessories, place the material to be processed on the lower mold 4, and then start the motor 15 to drive the driving gear 1 to rotate. The driving gear 1 is meshed with the driven gear 14, so that the driving gear 1 will drive the driven gear 14 to rotate when it rotates, thereby driving the rotating seat 16 to rotate and causing the turntable 5 to rotate. When the turntable 5 is rotating, the infrared transmitter 13 will always send out an infrared light signal downward. When the turntable 5 rotates to a certain extent, the infrared light signal sent by the infrared transmitter 13 will be received by the infrared receiver 3 and converted into an electrical signal, which will then be transmitted to the controller. The controller receives the electrical signal from the infrared receiver 3 and processes it, and then controls the motor 15 to stop rotating, so that the turntable 5 stops rotating, so that the corresponding lower mold 4 stops accurately above the upper mold 7, and then starts the hydraulic rod 9 to move its driving end downward, driving the upper mold 7 to move downward, and limit the position with the cooperation of the guide rod 8. , so that the material to be processed is bent by the cooperation of the lower mold 4 and the upper mold 7. During bending, the upper mold 7 will simultaneously apply downward pressure to the top plate 12 when bending the material, so that the spring 11 and the telescopic rod 10 are compressed. When the bending is completed, the hydraulic rod 9 is started to move the upper mold 7 upward, and then the motor 15 is started again to rotate, and with the cooperation of the infrared transmitter 13 and the infrared receiver 3, the material on the other lower mold 4 is bent. At the same time, during the bending work, the lower mold 4 after the material is bent will rotate to the outside. At this time, the top plate 12 is no longer subjected to the pressure of the upper mold 7, so that the top plate 12 will be driven to move upward under the action of the rebound force of the spring 11, and the formed accessories will be pushed out of the lower mold 4, so that it is convenient for the staff to take out and replace the new material to be processed. After a lower mold 4 completes stamping, the turntable 5 can be rotated to move the next lower mold 4 to the stamping position, thereby realizing continuous stamping, which greatly improves the production efficiency.

[0027] The wiring diagram of the infrared receiver 3, hydraulic rod 9, infrared transmitter 13 and motor 15 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the infrared receiver 3, hydraulic rod 9, infrared transmitter 13 and motor 15 are no longer explained in detail.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
