Description

Technical Field

[0001] The utility model relates to a processing device, in particular to a fin processing device. Background Art

[0002] Heat sink fins are a common heat dissipation component, typically made of metal (such as aluminum or copper). They are used to increase the heat exchange area, thereby improving heat dissipation efficiency. They are commonly used in electronic devices, automotive engines, and other applications requiring efficient heat dissipation.

[0003] Existing stamping machines usually process the fins and then polish the fins as a whole. During the stamping process, the deformation of various parts of the fins will accumulate, resulting in an increased risk of overall deformation. After the overall deformation, additional processes are required to correct the fins, and the correction is difficult, which increases production time and production costs. Utility Model Content

The guide rail 201 is symmetrically arranged on the front and back of the inner side of the support frame 101. The top of the support frame 101 is provided with a hydraulic cylinder 3. The bottom of the piston rod on the hydraulic cylinder 3 is connected to the mobile frame 4. The bottom of the mobile frame 4 A punching tool 17 is provided, and guide rods 15 are provided on the front and rear sides of the top of the movable frame 4. The guide rods 15 slide through the support frame 101, and the two guide rods 15 are respectively located on the front and rear sides of the hydraulic cylinder 3. Slide blocks 16 are provided at the front and rear ends of the movable frame 4. The slide blocks 16 are slidably connected to the guide rail 201.

[0025] like Figure 2 and Figure 3 As shown, the polishing jet mechanism includes a frame 5, a rodless cylinder 6, a jet block 7, an air pump 8, a first gear 901, a second gear 902, a rack 903, an electric slide rail 701, a polishing rod 9 and a control panel 22. A frame 5 is provided on the left side of the movable frame 4, a rodless cylinder 6 is provided in the frame 5, an air pump 8 is provided at the front end of the frame 5, and a control panel 22 is provided at the rear end of the frame 5. The jet block 7 is connected to the movable part of the rodless cylinder 6. Several through holes are provided at the bottom of the jet block 7, and a jet head is installed on each through hole. The air pump 8 is connected to the jet block 7 through an air pipe. Several polishing rods 9 are connected to the bottom of the jet block 7. The number, size and shape of the polishing rods 9 are consistent with the blade of the stamping tool 17 to ensure that the fin 20 corresponding to each blade can be fully polished. Thereby, the uniformity of grinding and the surface quality of the fin 20 are improved, and the bottom of the grinding rod 9 is higher than the stamping tool 17, which avoids the grinding rod 9 from colliding with the fin 20 during the stamping process and causing damage; the top of the grinding rod 9 is connected to a first gear 901, and a second gear 902 is connected between every two first gears 901, and the second gear 902 and the first gear 901 are meshed with each other. An electric slide rail 701 is provided in the jet block 7, and a rack 903 is connected to the moving part of the electric slide rail 701. The rack 903 is located on the side of the second gear 902 away from the first gear 901, and the rack 903 is meshed with the second gear 902. The electric slide rail 701, the photoelectric sensor 21, the conveyor belt 2, the hydraulic cylinder 3, the air pump 8 and the rodless cylinder 6 are all electrically connected to the control panel 22.

[0026] like Figure 1 As shown, a collection frame 801 is also included. The top of the base 1 is provided with a collection frame 801, and the collection frame 801 is used to collect debris generated after grinding.

[0027] like Figure 5 and Figure 6 As shown, it also includes a fixed seat 10, an L-shaped plate 11, a sleeve 12, an elastic member 13, a contact block 14, a contact rod 141 and a slide rod 18. A fixed seat 10 is provided on the right side of the top of the base 1. There are two fixed seats 10 and they are respectively located on the front and rear sides of the conveyor belt 2. A groove 19 is opened on the top of the fixed seat 10. The tops of the two fixed seats 10 are slidably connected to the L-shaped plate 11 through the groove 19. The side of the L-shaped plate 11 away from the conveyor belt 2 is provided with a slide rod 18. The outer side of the slide rod 18 is slidably connected with the sleeve 12. The elastic member 13 is connected between the sleeve 12 and the L-shaped plate 11. The end of the sleeve 12 away from the slide rod 18 is provided with a contact block 14. Two contact rods 141 are provided on the right side of the movable frame 4. The two contact rods 141 are respectively located directly above the two contact blocks 14, and the height of the contact rod 141 is lower than the stamping tool 17. The two contact blocks 14 are designed as inclined surfaces with a height gradually decreasing from the middle to both sides.

[0028] like Figure 7 As shown, nylon patches 111 are also included. Nylon patches 111 are provided on the inner sides of the two L-shaped plates 11. The nylon patches 111 can reduce the friction between the L-shaped plates 11 and the fins 20 and reduce the wear of the fins 20.

[0029] Pull open the L-shaped plate 11, place the fin 20 between the two L-shaped plates 11, start the conveyor belt 2, and the conveyor belt 2 moves the fin 20 to the left. When the fin 20 moves between the two photoelectric sensors 21, the light emitted by the generator in the photoelectric sensor 21 is blocked by the fin 20. The receiver does not receive the light emitted by the transmitter and waits for the first predetermined time (the first predetermined time is the ratio of the blade length of the punching tool 17 to the running speed of the conveyor belt 2). Then, an electrical signal is sent to the control panel 22, and the control panel 22 sends a stop signal to the conveyor belt 2, and the conveyor belt 2 stops running. At the same time, the control panel 22 sends a start signal to the hydraulic cylinder 3, and the hydraulic cylinder 3 performs a punching action. The piston rod on the hydraulic cylinder 3 drives the punching tool 17 to move vertically downward to punch the fin 20. After the punching is completed, the piston rod on the hydraulic cylinder 3 moves upward. Move and lift the stamping tool 17 to its original position, the control panel 22 starts the conveyor belt 2 and after the second predetermined time (the second predetermined time is the ratio of the length of the entire stamping tool 17 to the running speed of the conveyor belt 2), the conveyor belt 2 is closed and the hydraulic cylinder 3, the electric slide 701, the air pump 8 and the rodless cylinder 6 are started. While the hydraulic cylinder 3 is stamping, the rodless cylinder 6 drives the jet block 7 to move back and forth in the frame 5, the electric slide 701 drives the rack 903 to move back and forth, and the rack 903 drives the first gear 901 to rotate through the second gear 902, thereby rotating the polishing rod 9 to complete the polishing of the fin 20 after the previous impact, and the air pump 8 supplies air to the jet block 7 through the air pipe, causing the jet block 7 to spray gas and blow the debris generated after polishing into the collection frame 801. Repeat the above steps to finally complete the processing of the fin 20.
