Description

Technical Field

[0001] This utility model belongs to the field of heat sink fin punching and flanging technology, and particularly relates to a heat sink fin punching and flanging device. Background Technology

[0002] A radiator is assembled from dozens to hundreds of heat dissipation fins. During the processing of the radiator fins, punching and flanging are required. However, with existing punching and flanging dies, the waste material after punching and flanging is not easy to clean up. Utility Model Content

[0003] In view of the shortcomings of the prior art, the present invention provides a punching and flanging device for radiator fins, which solves the technical problem that the waste material after punching and flanging is not easy to clean after punching and flanging the radiator fins by the existing punching and flanging mold.

[0004] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0005] A punching and flanging device for radiator fins includes a stationary die and a moving die. It further includes a machine body. The stationary die is fixedly mounted on the upper surface of the machine body, and a through hole is formed within the stationary die, communicating with the interior of the machine body. A punch is fixedly mounted on the bottom of the moving die. A pair of third guide rods are fixedly mounted inside the machine body. A slider is slidably mounted on the pair of third guide rods. A support frame is fixedly mounted on the top surface of the slider. A groove is formed within the support frame. A pair of first guide rods are fixedly mounted within the groove. An L-shaped clamping plate is slidably mounted on the pair of first guide rods. A first spring is sleeved on the first guide rod, pressing against the right surface of the L-shaped clamping plate. A fixed clamping plate is fixedly mounted on the left side of the upper surface of the support frame. A waste box is clamped between the fixed clamping plate and the L-shaped clamping plate. A brake reduction motor is fixedly mounted on the bottom surface of the slider. A gear is fixedly mounted on the drive shaft of the brake reduction motor. A rack is fixedly mounted on the bottom surface of the machine body, meshing with the gear. A buffer device is provided on the right wall of the machine body.

[0006] Furthermore, the buffer device includes a pair of second guide rods, which are slidably connected to the right wall of the machine body. A buffer plate is fixedly provided on the left end of the pair of second guide rods. A second buffer pad is fixedly provided on the left end of the buffer plate. A second spring is sleeved on the second guide rod, and the second spring presses against the buffer plate. A limiting plate is fixedly provided on the right end of the pair of second guide rods.

[0007] Furthermore, a bell is installed on the right surface of the limiting plate.

[0008] Furthermore, a plurality of support columns are fixedly provided on the upper surface of the machine body, and a movable plate is slidably provided on the side surfaces of the plurality of support columns. The movable plate is fixedly provided with the moving mold, and a cross frame is fixedly provided on the upper ends of the plurality of support columns. A hydraulic cylinder is fixedly installed on the bottom surface of the cross frame, and the telescopic end of the hydraulic cylinder is fixedly connected to the movable plate.

[0009] Furthermore, anti-slip pads are fixedly provided at the opposing ends of both the fixed clamping plate and the L-shaped clamping plate.

[0010] Furthermore, a first buffer pad is fixedly provided on the lower left surface of the L-shaped clamp.

[0011] The beneficial effects of this utility model are:

[0012] 1. The moving plate descends, driving the moving mold and punch to descend, punching and flanging the workpiece. Scrap material falls from the through hole into the scrap box. The slider moves to the left, causing the scrap box to pass through the through opening. When the first buffer pad contacts the left wall of the machine body, the L-shaped clamping plate compresses the first spring, causing the L-shaped clamping plate to move away from the fixed clamping plate, thus allowing the scrap box to be removed and the scrap material inside to be cleaned.

[0013] 2. After cleaning, place the waste box between the fixed clamp and the L-shaped clamp. The clockwise rotation of the gear will move the slider to the right. The push force of the first spring on the L-shaped clamp will make the L-shaped clamp and the fixed clamp clamp the waste box.

[0014] 3. When the support frame contacts the second buffer pad, the bell will shake and make a sound. When the operator hears the bell, he / she will turn off the brake reduction motor. At this time, the waste box is located below the through hole. Attached Figure Description

Remove and clean the waste in the waste box 23. After cleaning, place the waste box 23 between the fixed clamping plate 22 and the L-shaped clamping plate 18. The reverse rotation of the brake reduction motor 14 can drive the gear 15 to rotate clockwise. The clockwise rotation of the gear 15 can drive the slider 13 to move to the right. The push force of the first spring 21 on the L-shaped clamping plate 18 can make the L-shaped clamping plate 18 and the fixed clamping plate 22 clamp the waste box 23. When the support frame 12 contacts the second buffer pad 24, the second buffer plate 25 drives the limit plate 28 to move. The movement of the limit plate 28 can drive the bell 29 to shake. The bell 29 shakes and makes a sound. When the operator hears the bell, turn off the brake reduction motor 14. At this time, the waste box 23 is located below the through hole 10.
