[0021] Embodiment 1

[0022] A precision compound punching die for hardware processing, as Figures 1-3 shown, includes a base 1. Guide cylinders 2 are connected to the four corners at the top of the base 1. A female die seat 3 is slidably connected between the guide cylinders 2. Four first springs 4 are connected between the female die seat 3 and the guide cylinders 2. Guide posts 5 are connected to the four corners at the top of the female die seat 3. A male die seat 6 is slidably arranged between the guide posts 5. The male die seat 6 and the female die seat 3 cooperate to punch the hardware parts. A transfer seat is connected to the top of the male die seat 6, and the transfer seat is used to connect with the telescopic end of a hydraulic cylinder or a cylinder. A top ejection mechanism 7 for ejecting the hardware parts after punching is arranged on the base 1.

[0023] As Figure 1 、 Figure 2 and Figure 4 The ejection mechanism 7 includes a pushing cylinder 71. The pushing cylinder 71 is installed on the rear side of the base 1 by bolts. The telescopic rod of the pushing cylinder 71 is arranged upward. Mounting brackets 72 are connected to both the left and right sides of the base 1. Rotating plates 73 are connected to the mounting brackets 72. The rotating plates 73 are embedded in the female die seat 3. Rotating groove plates 74 are connected to both the front and rear sides of the rotating plates 73. Two torsion springs 75 are connected between the rotating plates 73 and the adjacent mounting brackets 72. The top of the telescopic rod of the pushing cylinder 71 is connected with a first connecting rod 76, and the first connecting rod 76 is slidably and rotatably connected with the corresponding rotating groove plate 74.

[0024] It should be noted that when punching hardware parts, this device can be used to achieve auxiliary operations. First, place the hardware parts to be punched on the female die seat 3. Then, connect the adapter seat to the telescopic end of the cylinder or hydraulic cylinder. Next, start the cylinder or hydraulic cylinder to make the male die seat 6 move downward along the guide post 5, so that the male die seat 6 can engage with the female die seat 3, thereby completing the punching operation on the hardware parts. During the punching process, the first spring 4 can effectively buffer the extrusion force received by the female die seat 3. After punching is completed, control the male die seat 6 to reset. At this time, start the pushing cylinder 71. The downward contraction movement of the telescopic rod of the pushing cylinder 71 will drive the first connecting rod 76 to move downward, thereby making the rotating groove plate 74 rotate downward, and then making the rotating plate 73 flip upward, and the torsion springs 75 are all deformed by force. As the rotating plate 73 flips upward, it will push the hardware parts that have completed punching upward, so as to separate from the female die seat 3, which is convenient for the operator to quickly take out. After that, as the first connecting rod 76 is driven by the pushing cylinder 71 to reset, under the action of the torsion spring 75, the rotating plate 73 will drive the corresponding rotating groove plate 74 to reset.

[0025] Embodiment 2

[0026] Based on Embodiment 1, as Figure 1 , Figure 2 , Figure 4 and Figure 5 shown, it further includes a waste discharge mechanism 8. The waste discharge mechanism 8 includes a guide groove plate 81. The middle part inside the base 1 is connected with a guide groove plate 81, and the guide groove plate 81 is used to guide the discharge of the waste generated by punching. The guide groove plate 81 is a downward inclined structure. The middle part inside the base 1 is connected with a mounting frame 82. A knocking member 83 for knocking the bottom of the guide groove plate 81 is rotatably connected to the mounting frame 82. Three second springs 84 are connected between the knocking member 83 and the mounting frame 82. A wedge-shaped guide frame 87 is connected to the rear side of the base 1. A sliding pressing block 86 is slidably connected to the wedge-shaped guide frame 87, and the sliding pressing block 86 is used to squeeze and push the knocking member 83. A guide groove frame 85 is connected to the telescopic rod of the pushing cylinder 71, and the guide groove frame 85 is slidably connected to the sliding pressing block 86.

[0027] It should be noted that as the telescopic rod of the driving cylinder 71 moves downward and contracts, the guide groove frame 85 will move downward synchronously and push the sliding pressing block 86 downward, thereby squeezing the knocking member 83, causing the knocking member 83 to flip downward, and the second spring 84 will be compressed under force. At the same time, when the sliding pressing block 86 slides downward, it will be guided by the wedge-shaped guide frame 87 and start to slide backward, and gradually disengage from the knocking member 83 during the sliding process. When the sliding pressing block 86 disengages from the knocking member 83, under the action of the second spring 84, the knocking member 83 will quickly flip upward and reset, and under the action of elastic potential energy, it will knock on the bottom of the guide groove plate 81, preventing the waste generated by punching from accumulating on the upper part of the guide groove plate 81 and causing blockage to the subsequent discharge of waste.

[0028] The above are only examples of the implementation of the present utility model and are not intended to limit the present utility model. Any equivalent replacement made within the principle of the present utility model shall be included within the protection scope of the present utility model. The content not elaborated in detail in the present utility model belongs to the known prior art of those skilled in the art.
