A punching groove 15 is provided on the top of the punching seat 6, realizing automatic adjustment of different types of punching heads 14 to meet people's needs for punching different types of holes in the steel plate 7.

[0037] To ensure the entire mold provides good cushioning during the punching process, refer to... Figures 1-2 The top outer wall of the lower mold base 1 has a groove 10, and the bottom inner wall of the groove 10 is fixedly connected to a first fixing cylinder 3. A slide rod 4 is inserted into the inside of the first fixing cylinder 3. The top end of the slide rod 4 is fixedly connected to the bottom outer wall of the upper mold base 8. A first spring 5 is sleeved on the circumferential outer wall of the slide rod 4, which can effectively extend the service life of the entire mold.

[0038] To ensure that motor 13 remains stable throughout the die punching process, refer to... Figure 2 A fixing plate 12 is fixedly connected to the bottom outer wall of the upper mold base 8. The fixing plate 12 is fixedly connected to the motor 13. There are two sets of fixing plates 12. The fixing plates 12 can play a certain role in reinforcing the motor 13.

[0039] To achieve a good balance, refer to Figures 3-4One end of the rotating rod is fixedly connected to a counterweight 17, which is rotatably connected to another fixed plate 12. A round shell 9 is fixedly connected to one side of the outer wall of the fixed plate 12. The round shell 9 is fitted outside the counterweight 17 to prevent the punching head 14 from being affected by the tilted weight during the vertical downward punching process due to the weight of the motor 13, thus reducing the punching quality.

[0040] To ensure the rotating seat 11 remains stable during punching, refer to Figure 4 A rotating seat 11 is fixedly connected to the bottom outer wall of the upper mold base 8. The rotating seat 11 is rotatably connected to the rotating rod, which provides good support for the rotating seat 11.

[0041] In order to provide a certain buffer for the punching head 14 during the punching process, refer to Figures 3-4 The outer circumference of the round shell 9 is provided with a mounting hole. A second fixing cylinder 19 is fixedly connected inside the mounting hole. A second spring 20 is fixedly connected to the top inner wall of the second fixing cylinder 19.

By inserting the locking post 21 into the inside of the locking hole 18, it can play an auxiliary locking role, ensuring that the mounting base 16 and the motor 13 can always remain stable during the punching process. This not only ensures the punching quality, but also extends the service life of the motor 13 and the punching head 14.

[0044] Working principle: When in use, the operator first places the steel plate 7 to be punched on the top of the punching seat 6. Then, as the upper die seat 8 descends rapidly, it can drive the punching head 14 to punch the steel plate 7. When the operator needs to punch holes of different specifications or types on the steel plate 7, the motor 13 can be started. The motor 13 can drive the rotating rod and the mounting seat 16 to rotate together. During the rotation of the mounting seat 16, it can drive the four sets of punching heads 14 to rotate together until the different types of punching heads 14 rotate to the vertical downward position, thereby realizing the automatic adjustment of different types of punching heads 14 to meet people's needs for punching different types of holes on the steel plate 7.

[0045] When the punch head 14 punches the steel plate 7, the counterweight 17 set at the other end of the rotating rod can play a good balancing role, avoiding the situation where the punch head 14 is affected by the tilting weight due to the weight of the motor 13 during the vertical downward punching process, which would reduce the punching quality. When the punch head 14 punches downward, the pressure plate 23 will first contact the punching seat 6. At this time, the pressure plate 23 will drive the top column 22 to rise together. The second spring 20 located in the second fixed cylinder 19 will immediately deform and compress, thereby playing a certain buffering role. During the rise of the top column 22, it can drive the locking column 21 to rise together. When the punch head 14 contacts the steel plate 7, the locking column 21 has been inserted into the locking hole 18 on the outer wall of the counterweight 17, thereby playing an auxiliary locking role. This ensures that the mounting seat 16 and the motor 13 can always remain stable during the punching process, which not only ensures the punching quality, but also extends the service life of the motor 13 and the punch head 14.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
