[0031] In this embodiment, in order to prevent the punching hole 3 inside the lower die 2 from being deformed, when the die is in use, the upper die assembly moves downward, and the punching head 5 in the upper die assembly punches the steel plate by cooperating with the punching hole 3. When the punching head 5 moves downward, it drives the punched waste material to slide inside the punching hole 3. At the same time, the punching head 5 pushes the protective die head 13 to move downward along the punching hole 3 through the waste material, so that the inside of the punching hole 3 is filled and supported by the punching head 5 and the protective die head 13 during the punching process of the steel plate, preventing the punching hole 3 from being deformed due to insufficient bearing capacity, protecting the punching hole 3 in the lower die 2, and improving the service life.

[0032] Among them, in order to achieve the purpose of not affecting the discharge of waste under punching, the present device is implemented by the following technical scheme: the upper die assembly includes an upper die 4, the upper die 4 is arranged on the top of the lower die 2, and a punch head 5 is fixedly arranged at the bottom of the upper die 4, the punch head 5 passes through the punching hole 3 and is slidably connected to the punching hole 3, the reset assembly includes a fixed plate 15, the fixed plate 15 is fixedly arranged on the top of the support plate 10, and two reset units are arranged on one side of the fixed plate 15, and the reset unit includes a guide rod 16, one end of the guide rod 16 is fixedly connected to the fixed plate 15, the guide rod 16 passes through the protective template 12 and is slidably connected to the protective template 12, and the other end of the guide rod 16 is fixedly provided with a baffle 17, and a spring 18 is sleeved on the outside of the guide rod 16, and one end of the spring 18 is fixedly connected to the fixed plate 15, and the spring 1 The other end of 8 is fixedly connected to the protection template 12. When the protection die head 13 moves downward, the support plate 10 moves downward through the protection template 12. The movement of the support plate 10 causes the spring 19 to contract. At the same time, when the protection template 12 moves, the sliding column 14 cooperates with the track groove 9 to control the trajectory of the protection template 12 when it moves. When the sliding column 14 moves to the inclined end of the track groove 9, the protection die head 13 is separated from the inside of the punching hole 3. At this time, the protection template 12 continues to descend and the protection template 12 moves to the left through the cooperation of the sliding column 14 and the track groove 9. The movement of the protection template 12 causes the spring 18 to contract. At the same time, the protection die head 13 is misaligned with the punch head 5, which is convenient for waste to fall between the punch head 5 and the protection die head 13 without affecting the normal discharge of waste.

[0033] In order to achieve the purpose of resetting the protection die head 13 after the punch head 5 is reset, the device adopts the following technical solutions: the support plate 10 is arranged between the two side plates 8 and is slidably connected to the two side plates 8, the connecting ring 11 is sleeved on the outside of the support column 6 and is slidably connected to the support column 6, the protection template 12 is arranged on the top of the support plate 10 and is slidably connected to the top of the support plate 10, the top of the protection die head 13 extends into the inside of the punch hole 3 and is slidably connected to the punch hole 3, the sliding column 14 extends into the inside of the track groove 9 and is slidably connected to the track groove 9, and the spring 12 is arranged on the outside of the support column 6 and is slidably connected to the support column 6. The top of 9 is fixedly connected to the bottom of the support plate 10, and the bottom of the spring second 19 is fixedly connected to the top of the bottom plate 7. When the upper die 4 drives the punch head 5 to reset upward, the contracted spring one 18 resets the protection template 12 through elastic force, and the baffle 17 prevents the protection template 12 from shaking left and right when it is reset. At the same time, the contracted spring two 19 uses elastic force to make the support plate 10 drive the protection template 12 to reset upward, so that the protection die head 13 can be inserted into the punching hole 3, so that the protection die head 13 is reset, which is convenient for the next punching operation.

[0034] The use process of the utility model is as follows: when using the utility model, it is connected with the stamping equipment to control the opening and closing of the lower die 2 and the upper die 4. When punching the steel plate mesh, first put the steel plate on the lower die 2 so that the area to be punched is located directly above the lower die 2 and directly below the punching head 5. When in use, the upper die 4 drives the punching head 5 to move downward, and the punching head 5 punches the steel plate by cooperating with the punching hole 3. When the punching head 5 moves downward, it drives the punched waste to slide inside the punching hole 3. At the same time, the punching head 5 pushes the protective die head 13 to move downward along the punching hole 3 through the waste material, so that the inside of the punching hole 3 is filled and supported by the punching head 5 and the protective die head 13 during the punching process of the steel plate, preventing the punching hole 3 from being deformed due to insufficient bearing capacity, protecting the punching hole 3 in the lower die 2, and improving the service life. When the protective die head 13 moves downward, the support plate 10 moves downward through the protective template 12. The movement of the support plate 10 causes the spring 2 19 to contract, and at the same time, the protective die head 13 When the template 12 moves, the trajectory of the protection template 12 is controlled by the cooperation between the sliding column 14 and the track groove 9. When the sliding column 14 moves to the inclined end of the track groove 9, the protection die head 13 is separated from the inside of the punching hole 3. At this time, the protection template 12 continues to descend and the cooperation between the sliding column 14 and the track groove 9 makes the protection template 12 move to the left. The movement of the protection template 12 causes the spring 18 to contract. At the same time, the protection die head 13 is misaligned with the punching head 5, which is convenient for the waste to fall from between the punching head 5 and the protection die head 13 without affecting the normal discharge of the waste. When the upper mold 4 drives the punching head 5 to reset upward, the contracted spring 18 resets the protection template 12 through elastic force, and the baffle 17 prevents the protection template 12 from shaking left and right when it is reset. At the same time, the contracted spring 2 19 uses elastic force to make the support plate 10 drive the protection template 12 to reset upward, so that the protection die head 13 can be inserted into the inside of the punching hole 3, so that the protection die head 13 is reset, which is convenient for the next punching operation.
