[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for production and processing of aluminum substrates. Background Art

[0002] Aluminum substrate is a metal-based copper-clad laminate with good heat dissipation function. Generally, a single-sided board consists of three layers, namely the circuit layer (copper foil), the insulation layer and the metal base layer. It is commonly used in LED lighting products. There are two sides, the white side is for welding LED pins, and the other side is the original color of aluminum. Generally, thermal conductive slurry is applied to contact the thermal conductive part. There are also ceramic substrates, etc. Often in the process of producing aluminum substrates, it is often necessary to punch the produced aluminum substrates for easy installation.

[0003] When the punching device is punching, when the pressure head moves down, the outer side of the pressure head will pull the aluminum substrate to a certain extent, which will cause burrs to appear on the edge of the punching hole, which will affect the subsequent installation work and reduce the punching effect.

[0010] Preferably, the upper end of the contact block is arranged in an arc shape.

[0011] Preferably, the upper end of the air pipe is inclined and aligned with the pressure hole.

[0012] Beneficial effects of the utility model:

[0022] like Figure 1-3 As shown, the utility model provides a punching device for aluminum substrate production and processing, including a workbench 1, the aluminum substrate to be punched is placed on the upper end of the workbench 1 for processing, the upper end of the workbench 1 is provided with a pressing hole 18, the upper end of the workbench 1 is fixedly connected with a top plate 2, both sides of the lower end of the top plate 2 are fixedly connected with hydraulic rods 4, the lower end of the hydraulic rod 4 is fixedly connected with a support plate 3, the hydraulic rod 4 moves downward, driving the support plate 3 to move downward, the lower end of the support plate 3 is movably connected with a pressure head 6, and a grinding mechanism is provided inside the workbench 1;

[0023] The grinding mechanism includes a grinding block 5 fixedly connected to the surface of the pressure head 6, and the filled hole can be ground by the provided grinding block 5. The upper end of the pressure head 6 is rotatably connected to the lower end of the support plate 3. A cavity 7 is provided inside the workbench 1, and a support column 12 is fixedly connected inside the cavity 7. A threaded rod 13 is connected to the internal thread of the support column 12. When the threaded rod 13 moves up and down, the threaded rod 13 rotates under the action of the support column 12. The upper end of the threaded rod 13 is fixedly connected to the contact block 17, and the rotation of the threaded rod 13 drives the contact block 17 to rotate. A spring 11 is sleeved on the outer side of the support column 12, and the spring 11 is used to reset the contact block 17. The lower end of the contact block 17 is rotatably connected to a rotating block 16, and the lower end of the rotating block 16 is fixedly connected to the upper end of the spring 11. The provided rotating block 16 can avoid direct contact between the spring 11 and the rotating block 16, thereby reducing friction. The upper end of the contact block 17 is arranged in an arc shape, and the arc shape is convenient for discharging waste.

[0024] When working, the aluminum substrate that needs to be punched is placed on the upper end of the workbench 1. At this time, the hydraulic rod 4 drives the support plate 3 to move downward, and the support plate 3 drives the pressure head 6 to move downward. Punching is achieved under the action of the pressure hole 18. When the pressure head 6 moves downward, it contacts the contact block 17, so that the contact block 17 drives the threaded rod 13 to move downward, and at the same time compresses the spring 11. When the threaded rod 13 moves downward, under the action of the support column 12, the contact block 17 is driven to rotate. The upper end of the contact block 17 is provided with rubber, which can increase the friction between the contact block 17 and the pressure head 6, and then the contact block 17 drives the pressure head 6 to rotate, and the pressure head 6 drives the grinding block 5 to rotate. Under the action of the spring 11, the contact block 17 can always be in contact when the pressure head 6 moves up and down, thereby realizing grinding of the punched hole and improving the quality of the punched hole.

[0025] like Figure 1-3 As shown, both sides of the cavity 7 are fixedly connected with a gas cylinder 8, the inner wall of the gas cylinder 8 is slidably connected with a piston plate 9, the piston plate 9 and the inner wall of the gas cylinder 8 are in a sealed state, the upper end of the piston plate 9 is fixedly connected with an L-shaped support rod 14, the L-shaped support rod 14 moves up and down to drive the piston plate 9 to move up and down, the L-shaped support rod 14 is fixedly connected to the rotating block 16, the inside of the piston plate 9 is fixedly connected with a one-way valve 10, the one-way valve 10 can only flow gas in one direction, the upper end of the gas cylinder 8 is fixedly connected with an air pipe 15, the air pipe 15 is used to conduct gas, the upper end of the air pipe 15 is inclined, and the upper end is aligned with the pressure hole 18;

[0026] When the rotating block 16 moves up and down, it drives the L-shaped support rod 14 to move up and down, and the L-shaped support rod 14 drives the piston plate 9 to move up and down. Under the action of the one-way valve 10, when the piston plate 9 moves up, the gas at the upper end of the piston plate 9 is squeezed into the inside of the air pipe 15, and the debris generated during grinding is blown away by the gas, thereby further improving the punching effect.

[0027] like Figure 1-3 As shown, rectangular openings are provided on both sides of the lower end of the cavity 7, and the rectangular openings are inclined so that waste can be easily discharged through the rectangular openings.

[0028] Working principle: When working, the aluminum substrate to be punched is placed on the upper end of the workbench 1. At this time, the hydraulic rod 4 drives the support plate 3 to move downward, and the support plate 3 drives the pressure head 6 to move downward. Punching is achieved under the action of the pressure hole 18. When the pressure head 6 moves downward, it contacts the contact block 17, so that the contact block 17 drives the threaded rod 13 to move downward, and at the same time compresses the spring 11. When the threaded rod 13 moves downward, under the action of the support column 12, the contact block 17 is driven to rotate. The upper end of the contact block 17 is provided with rubber, which can increase the friction between the contact block 17 and the pressure head 6, and then the contact block 17 drives the pressure head 6 to rotate, and the pressure head 6 drives the grinding block 5 to rotate. Under the action of the spring 11, the contact block 17 can always be in contact when the pressure head 6 moves up and down, thereby realizing grinding of the punched hole and improving the quality of the punched hole.

[0029] Furthermore, when the rotating block 16 moves up and down, it drives the L-shaped support rod 14 to move up and down, and the L-shaped support rod 14 drives the piston plate 9 to move up and down. Under the action of the one-way valve 10, when the piston plate 9 moves up, the gas at the upper end of the piston plate 9 is squeezed into the interior of the air pipe 15, and the gas is used to blow away the debris generated during grinding, thereby further improving the punching effect.
