However, the operation is cumbersome and time-consuming, which greatly reduces work efficiency. The blanked sheet cannot be removed well. The blanked material is easily stuck in the middle of the sheet, which requires additional steps to remove, making it inconvenient to use. When the punching die needs to be replaced, the disassembly and assembly of the cutting die is not convenient enough, the disassembly and assembly space is small, it is not convenient for workers to operate, and the operation is difficult; When punching is required at different positions of the plate, the mold needs to be replaced due to the different positions, which increases the cost; Therefore, those skilled in the art provide a punching device for producing and processing a DC power supply panel to solve the problems raised in the above background technology.

[0026] In particular, a strip groove 40 is provided on one side of the second sleeve 29, and side holes 41 connected to the strip groove 40 are provided at both ends of one side of the second sleeve 29. A side rod 34 is slidably penetrated inside the side hole 41, and one end of the two side rods 34 is fixedly connected to the same front rod 38, and the front rod 38 is used in conjunction with the strip groove 40. The other ends of the two side rods 34 are fixedly connected to the same back rod 37, and one side of the back rod 37 is fixedly connected to a block 36, and one end of the block 36 slides through the second sleeve 29, and one side of the second inner rod 28 is provided with a card block engaged with the card block 36. Slot 42, one side of the back rod 37 and one side of the second sleeve 29 are fixedly connected with two symmetrically arranged first tension springs 35. When the plate needs to be punched, one side of the plate is used to press against the second sleeve 29. At this time, the plate will push the front rod 38, and the front rod 38 drives the two side rods 34 to move laterally. The front rod 38 enters the interior of the strip groove 40. At this time, the side rod 34 drives the back rod 37 to move laterally. The back rod 37 stretches the first tension spring 35 and drives the block 36 to move laterally. The block 36 moves out from the inside of the slot 42. At this time, the braking state of the fixed screw 2 can be released.

[0027] In particular, a nut 46 is threadedly sleeved on the outer wall of the fixing screw rod 2 , and the top of the nut 46 abuts against the bottom of the top plate 3 .

[0028] Working principle: When the sheet needs to be punched, one side of the sheet is pressed against the second sleeve 29, and the sheet pushes the front rod 38, which drives the two side rods 34 to move laterally, and the front rod 38 enters the interior of the strip groove 40. At this time, the side rod 34 drives the back rod 37 to move laterally, and the back rod 37 stretches the first tension spring 35 and drives the block 36 to move laterally, and the block 36 moves out of the interior of the groove 42, and the braking state of the fixed screw 2 can be released at this time; At this time, the second inner rod 28 moves downward under the tension of the fourth tension spring 39, and the second inner rod 28 drives the first pressure plate 11 to move downward. The first pressure plate 11 presses one side of the plate tightly and pushes the plate forward. The plate drives the second sleeve 29 to move forward. At this time, the second sleeve 29 drives the two arc blocks 33 to move horizontally and squeeze the first spring 16. The arc blocks 33 no longer conflict with the two first sleeves 18; At this time, the first sleeve 18 moves laterally under the elastic force of the compression spring 31, and the two first sleeves 18 approach each other and clamp the two sides of the plate. Since the bottom of one side of the second pressure plate 13 is set in an arc shape, the second pressure plate 13 and the first inner rod 17 will move up slightly to adapt to the thickness of the plate. After the plate is released, the second sleeve 29 is reset to a certain distance under the elastic force of the first spring 16. At this time, the side of the plate fed in conflicts with the side of the stopper 7, ensuring the stability of the plate and facilitating the subsequent punching process. The electric push rod 5 is started, and the piston rod of the electric push rod 5 drives the nut 46 to move downward, and the nut 46 drives the blanking frame 9 to move downward. The blanking frame 9 first drives the upper support plate 52 to move downward. When the bottom of the upper support plate 52 contacts the top of the plate, the upper support plate 52 no longer continues to descend, and the blanking frame 9 continues to move downward, thereby driving the plurality of second round rods 60 to move downward, which can ensure the stability of the movement of the blanking frame 9. Since the redundant outer part of the plate is cut off around the punching frame 9, and multiple punching blocks 57 are punching holes at appropriate positions of the plate, the back rod 37 is installed inside the threaded groove 58 through the threaded block 56. The size and shape of the punched hole can be adjusted by changing the size and shape of the back rod 37, which makes the operation more convenient. The sliding circular plate 54 is pressed against the top inner wall of the punching frame 9, and the fifth spring 53 is squeezed. The setting of the mounting screw 55 can prevent the upper support plate 52 from being offset. The setting of multiple threaded grooves 58 can also facilitate the change of the position of the punching block 57, reduce the use cost, and improve the application range of the device. When the multiple punching blocks 57 inside need to be replaced, the piston rod of the electric push rod 5 is retracted, the push block 45 is moved out from the inside of the third rectangular hole 51, and the top of the push block 45 pushes the extension rod 47 to move upward, and the extension rod 47 drives the sliding L-shaped plate 44 to move upward and squeeze the fourth spring 48, and the sliding L-shaped plate 44 is moved out from the inside of the rectangular groove 30, thereby releasing the braking state of the mounting plate 6; The mounting plate 6 is pulled out horizontally, and the mounting plate 6 drives the two side rectangular blocks 62 to move horizontally inside the slide groove 49. At this time, since the positioning rod 69 is always located inside the positioning groove 68, the mounting plate 6 cannot rotate. When the side rectangular block 62 moves to the inner wall of one side of the slide groove 49, the push rod 61 is resisted by the inner wall of the slide groove 49, and the push rod 61 drives the side block 64 to move horizontally. At this time, the side block 64 drives the positioning rod 69 to move horizontally, and the positioning rod 69 moves out of the interior of the positioning groove 68, which can release the braking state of the rotating shaft 63. At this time, the mounting plate 6 can be rotated. After the mounting plate 6 is turned over, the internal punching frame 9 can be leaked, thereby increasing the operating space, facilitating the replacement and movement of the punching block 57, greatly improving the work efficiency, and reducing the difficulty of operation; When the sheet metal is punched, the operating block 14 can be pressed, and the operating block 14 drives the stopper 7 to move downward, and the stopper 7 drives the first round rod 24 on one side to move downward, and through the connection of the rotating plate 22, the first round rod 24 on the other side can be driven to move upward, and then the connecting block 25 is driven to move upward, and the connecting block 25 drives the sliding block 26 and the lower support plate 8 to move upward, and the lower support plate 8 pushes out the punched sheet metal inside, which is convenient for users to take it out, and at the same time, the stopper 7 is retracted to the inside of the working platform 1, and the remaining frame outside can be directly pushed out by the elastic force of the first spring 16. At this time, the outer frame and the finished product inside are separated, which is convenient for next use.
