When working, the punch rod 1 is installed to the specified position, and then The punch rod 1 drives the punch output end 12 to work. At this time, the workpiece to be processed can be allowed to contact the punch output end 12, and then the workpiece is processed. At this time, the top of the workpiece contacts the second fixed plate 14, and the second fixed plate 14 slides in the middle of the punch rod 1, allowing the workpiece to push the second fixed plate 14 upward. Under the influence of the thrust, the two springs 15 will shrink inward, and at the same time, the two telescopic rods 16 can be driven to retract. At this time, the workpiece to be processed will be restricted due to the work of the springs 15 and the telescopic rods 16, and thus cannot rise quickly. Through such a structure, the workpiece and the punch output end 12 can be reduced from contacting too quickly, resulting in excessive impact on the workpiece, thereby causing the workpiece to be damaged or torn. At the same time, the spring 15 can be protected by arranging a telescopic rod 16 on the outside of the spring 15.

[0025] like Figure 3As shown, the middle part of the punch rod 1 is rotatably connected with a collar 2; a groove 21 is provided on a side wall of the collar 2 close to the punch rod 1; two first water holes 22 are provided on the side wall of the collar 2; the first water holes 22 are symmetrically arranged; a through hole 24 is provided in the middle part of the punch rod 1; two first water inlet holes 23 are provided in the middle part of the punch rod 1; the two first water inlet holes 23 are symmetrically arranged; the positions of the first water inlet hole 23 and the first water through hole 22 correspond, and the radius of the first water inlet hole 23 is smaller than the groove 21, and two water outlet holes 25 are provided in the middle part of the punch rod 1; the two water outlet holes 25 are symmetrically arranged; the water outlet holes 25 are located in the middle part of the punch rod 1 near the bottom When working, pipes are connected to the ends of the two grooves 21, and the inside of the ring 2 is flushed at the same time. At this time, as the punch rod 1 rotates, the water filled into the ring 2 will remain in the groove 21. At this time, the grip of the punch rod 1 will drive the water to rotate. At this time, water will pass through the first water inlet hole 23 and enter the inside of the punch rod 1. At this time, the inside of the punch rod 1 will be filled with liquid. At the same time, the liquid inside the punch rod 1 will flow to the outside of the punch rod 1 through multiple water outlet holes 25. Through such a structure, the inside of the punch rod 1 can be filled with liquid, and the liquid can be used to flush the workpiece debris on the surface of the second fixed plate 14. At the same time, the liquid can lubricate the workpiece processing part to reduce the occurrence of debris splashing.

[0026] like Figures 2 to 5 As shown, two second water holes 3 are provided at the bottom of the collar 2; the two second water holes 3 are symmetrically arranged; two through holes 32 are provided at the top of the first fixing plate 13; the two through holes 32 are symmetrically arranged; a second water inlet hole 33 is provided in the middle of the output end of the telescopic rod 16; the end of the second water hole 3 is connected to a water pipe 31; the water pipe 31 passes through the through hole 32 and extends to the output end of the telescopic rod 16, and extends to the inside of the output end of the telescopic rod 16 through the second water inlet hole 33; two leakage holes 34 are provided on the top of the second fixing plate 14; the two leakage holes 34 is symmetrically arranged. When working, the liquid inside the groove 21 can enter the output end of the telescopic rod 16 through the water pipe 31. At this time, the liquid is allowed to enter the output end of the telescopic rod 16 and then flow in through the leakage hole 34 on the surface of the second fixed plate 14, and contact the punch output end 12, and at the same time contact the workpiece being processed. Through such a structure, the surface of the punch output end 12 can be more lubricated, and the outflowing liquid can drip onto the workpiece, reducing the friction between the punch output end 12 and the workpiece, and reducing the damage to the spring 15 caused by splashing of debris during workpiece processing.

[0027] like Figure 1 and Figure 2As shown, two guide plates 4 are fixedly connected to the side wall of the second fixed plate 14; the two guide plates 4 are symmetrically arranged; the guide plates 4 are located on both sides of the punch output end 12. During operation, when the liquid flows to the punch output end 12 through the leakage hole 34, the liquid will be driven to rotate with the rotation of the punch rod 1. At this time, the rotating liquid is thrown away and cannot accurately flow to the punch output end 12. At this time, the guide plates 4 are installed on the side walls of the second fixed plate 14. Through such a structure, the thrown liquid can be blocked, allowing the liquid to flow to the surface of the punch output end 12 more accurately, thereby further increasing the lubrication of the punch output end 12.

[0028] like Figure 1 and Figure 2 As shown, two baffles 5 are fixedly connected to the end of the first fixed plate 13; the two baffles 5 are symmetrically arranged; the bottom of the baffle 5 is located at the same horizontal plane as the side wall of the second fixed plate 14. During operation, when the punch output end 12 contacts the workpiece, a lot of workpiece debris will be generated, and most of these debris are made of metal. At this time, the metal debris contacts the spring 15, the telescopic rod 16 and the water pipe 31, which may cause damage. At this time, symmetrical baffles 5 are installed on the side wall of the first fixed plate 13. Through such a structure, the debris splashed onto the surface of the spring 15, the telescopic rod 16 and the water pipe 31 can be blocked, thereby protecting the spring 15, the telescopic rod 16 and the water pipe 31 and increasing the service life of the device.

[0029] like Figure 5 As shown, a connecting rod 6 is fixedly connected to the middle of the water pipe 31; a fixing ring 61 is fixedly connected to the side wall of the connecting rod 6; the end of the fixing ring 61 is fixedly connected to the side wall of the telescopic rod 16; the fixing ring 61 is located below the spring 15. When working, the liquid inside the water pipe 31 flows all the way to the output end of the telescopic rod 16. At this time, the water pipe 31 is fixed below the first fixing plate 13 by installing the connecting rod 6 and the fixing ring 61, so that the water pipe 31 does not fall off when working. Through such a structure, the water pipe 31 can be fixed, thereby reducing the situation where there is no liquid in the output end of the telescopic rod 16 caused by the water pipe 31 falling off.

[0030] like Figure 3 As shown, the radii of the first water hole 22 and the first water inlet hole 23 are equal. Through such an arrangement, a portion of the liquid entering the groove 21 can directly enter the interior of the punch rod 1 through the first water inlet hole 23.

[0031] During operation, the punch rod 1 is installed to the specified position, and then the punch rod 1 drives the punch output end 12 to work. At this time, the workpiece to be processed can be allowed to contact the punch output end 12, and then the workpiece is processed. At this time, the top of the workpiece contacts the second fixed plate 14, and the second fixed plate 14 slides in the middle of the punch rod 1, allowing the workpiece to push the second fixed plate 14 upward. Under the influence of the thrust, the two springs 15 will shrink inward, and at the same time, the two telescopic rods 16 can be driven to retract. At this time, the workpiece to be processed will be due to the spring 1 5 and the telescopic rod 16 are restricted, so that they cannot rise quickly, and pipes are connected to the ends of the two grooves 21, and the inside of the ring 2 is flushed at the same time. At this time, as the punch rod 1 rotates, the water filled into the ring 2 will remain in the inside of the groove 21. At this time, the grip of the punch rod 1 will drive the water to rotate. At this time, the water will pass through the first water inlet hole 23 and enter the inside of the punch rod 1. At this time, the inside of the punch rod 1 will be filled with liquid. At the same time, the liquid inside the punch rod 1 will flow to the outside of the punch rod 1 through multiple water outlet holes 25. The liquid inside the groove 21 can enter the output end of the telescopic rod 16 through the water pipe 31. At this time, the liquid is allowed to enter the output end of the telescopic rod 16 and then flow in through the leakage hole 34 on the surface of the second fixed plate 14, and contacts the punch output end 12 and the workpiece being processed. When the liquid flows to the punch output end 12 through the leakage hole 34, the liquid will rotate with the rotation of the punch rod 1. At this time, the rotating liquid is thrown away, so that it cannot accurately flow to the punch output end 12. At this time, the liquid is passed through the second fixed plate 14. A guide plate 4 is installed on the side wall. When the punch output end 12 contacts the workpiece, a lot of workpiece debris will be generated, and most of these debris are made of metal. At this time, the metal debris contacts the spring 15, the telescopic rod 16 and the water pipe 31, which may cause damage. At this time, a symmetrical baffle 5 is installed on the side wall of the first fixed plate 13 so that the liquid inside the water pipe 31 flows all the way to the output end of the telescopic rod 16. At this time, the water pipe 31 is fixed under the first fixed plate 13 by installing a connecting rod 6 and a fixing ring 61, so that the water pipe 31 does not fall off when working.
