[0031] See also Figure 1-4 As shown, the utility model provides a technical solution of a steel punching device for forging high-toughness alloy steel: a steel punching device for forging high-toughness alloy steel, comprising a roller group frame 1, a movable roller group 2 is installed inside the roller group frame 1, a punching mechanism 3 is installed on the side of the roller group frame 1, and a lifting mechanism 4 for changing the moving direction of the steel is installed inside the roller group frame 1;

[0032] The lifting mechanism 4 includes a first drive motor 401, a rotating rod 402, and a second drive motor 405. The first drive motor 401 is installed on the side of the roller group frame 1, and the end of the rotating rod 402 is connected to the first drive motor 401. The two ends of the rotating rod 402 are fixedly connected to the connecting rod 403, and the other end of the connecting rod 403 is rotatably connected to the top rod 404. The second drive motor 405 is installed on the side of the roller group frame 1, and the output end of the second drive motor 405 is connected to the upper roller group 406, and the upper roller group 406 is arranged at the upper end of the mobile roller group 2. In the specific implementation process, the mobile roller group 2 and the upper roller group 406 are both composed of rollers and chain belts. The second drive motor 405 in this embodiment can be connected to any roller in the upper roller group 406. In order to prevent the flashing part of the cutting surface from damaging the knife groove 307 during the transmission of the steel, the lifting mechanism 4 is set up. During the lifting process, the first drive motor 401 drives the rotating rod 402 to rotate. At this time, the position of the push rod 404 at the end of the connecting rod 403 will also move from the middle part of the rotating roller of the moving roller group 2 to the top of the rotating roller and lift the end of the steel. When the upper and lower ends of the steel are in contact with the upper roller group 406 and the push rod 404, the cut surface of the steel is tilted and separated from the knife groove 307. At this time, the second drive motor 405 rotates to move the entire steel outward. When the cutting length is reached, the first drive motor 401 rotates, and the push rod 404 falls back to the initial position again. The steel lies flat, and the punching mechanism 3 will work again.

[0033] The punching mechanism 3 includes a punching frame 301, a cylinder 306, and a knife groove 307. The inside of the punching frame 301 is slidably connected with a pressure block 302 through a cavity. The inside of the pressure block 302 is slidably connected with a cutter 303 through a cavity. An extension portion 304 is provided on the side of the cutter 303. The extension portion 304 is restricted in the cavity inside the pressure block 302. A plurality of springs 305 are provided between the extension portion 304 and the pressure block 302. The cylinder 306 is provided on the top of the punching frame 301. The output end of the cylinder 306 is connected to the cutter 303. The knife groove 307 is provided in the inside of the punching frame 301. The knife groove 307 is located at the cutting Directly below the knife 303, during the punching process, the cylinder 306 provides power for the movement of the cutter 303 and the pressure block 302. When the steel reaches the cutting length, the roller group stops rotating, and the cylinder 306 roller group presses down the cutter 303. During the falling process, the lower end surface of the pressure block 302 will first contact the surface of the steel for positioning, and then as the cylinder 306 continues to output, the cutter 303 will cut the steel. After this process is completed, the cylinder 306 rises and the cutter 303 retracts into the pressure block 302 again. When the extension 304 of the cutter 303 is against the top of the cavity of the pressure block 302, it is lifted up, and the steel is restricted by contact and can be transmitted again.

[0034] A guide groove 5 is provided below the knife groove 307 , and the main function of the guide groove 5 is to guide and discharge metal debris generated during the punching process, thereby ensuring the cleanliness of the knife groove 307 and preventing debris accumulation from affecting the normal operation of the equipment.

[0035] A chip storage groove 6 is further configured at the outlet of the guide groove 5, and the chip storage groove 6 is specifically used to collect and store metal debris led out from the guide groove 5. The chip storage groove 6 is designed to facilitate regular cleaning of debris and prevent debris accumulation, thereby improving the maintenance efficiency and operational safety of the equipment.

[0036] The cutter 303 and its corresponding cutter groove 307 are both designed as a V-shaped structure, which not only improves the accuracy and efficiency of punching, but also helps to ensure that the punching debris is smoothly guided to the guide groove 5.

[0037] The top rod 404 is located in the middle part of the movable roller group 2, and the movable range of the top rod 404 is less than 50°. This design can ensure that the establishment of the lifting mechanism 4 will not interfere with the operation of the movable roller group 2, thereby maintaining the transmission efficiency and stability of the entire system.

[0038] The working principle of the utility model is as follows:

[0039] When the steel material punching device for forging high-toughness alloy steel of this embodiment is working, the moving roller group 2 first starts to convey the steel material and moves it to the punching mechanism 3. When the steel material reaches the cutting length, the roller group stops rotating, the cylinder 306 starts, and the cutter 303 is pressed down to cut. During the falling process of the cutter 303, the lower end surface of the pressing block 302 first contacts the surface of the steel material for precise positioning, and then the cylinder 306 continues to output and drives the cutter 303 to cut the steel material. After the cutting is completed, the cylinder 306 rises back, and the cutter 303 retracts into the pressing block 302 again. When the extension part 304 of the cutter 303 abuts against the top of the cavity of the pressing block 302, it is lifted up and the steel material is released. Then the first driving motor 401 starts, driving the rotating rod 402 to rotate, so that the connecting rod 403 moves, pushing the push rod 404 from the middle part of the rotating roller of the moving roller group 2 to the top of the rotating roller and lifting the end of the steel material. At this time, the upper and lower ends of the steel are in contact with the upper roller group 406 and the top rod 404 respectively, so that the cut surface of the steel is slightly tilted and separated from the knife groove 307. Finally, the second drive motor 405 is driven, and when the steel reaches the cutting position again, the steel is put down to avoid the influence of the cut surface flashing on the knife groove 307 during the transportation process.
