[0026] Reference Figure 1-4 A punching die for a door lock hole comprises a lower die 1 and an upper die 3. The door lock 6 is placed above the lower die 1. The four corners of the upper end of the lower die 1 are fixedly connected to guide rods 2. The upper die 3 is movably mounted on the outside of the four guide rods 2. A punching part 4 is connected to the bottom of the upper die 3. The upper die 3 is connected to an external driving mechanism to drive the upper die 3 to move longitudinally, so that the punching part 4 moves downward to perform the punching operation.

[0027] Specifically, the door lock 6 on the market is as follows Figure 2As shown, two mounting holes 7 will be opened on the surface and a through-hole 8 will be opened on the top. This device needs to punch a hole at the bottom of the door lock 6. The hole position and the through-hole 8 need to be coaxially designed, and the two mounting holes 7 are symmetrically distributed with the through-hole 8 as the center.

[0028] Specifically, such as Figure 2 As shown, the lower mold 1 is internally rotatably connected to a bidirectional screw rod 9, one side of the bidirectional screw rod 9 is connected to an adjusting knob 18, and the adjusting knob 18 is rotatably installed on the outside of the lower mold 1. The external thread of the bidirectional screw rod 9 is connected to two threaded sleeves 10, and the two threaded sleeves 10 are symmetrically distributed around the center of the bidirectional screw rod 9. Positioning columns 12 are fixed above the two threaded sleeves 10.

[0029] In this embodiment, the bidirectional screw 9 is rotated by rotating the adjusting knob 18, thereby causing the two threaded sleeves 10 connected to the external thread of the bidirectional screw 9 to move in opposite directions, causing the two positioning columns 12 to move in opposite directions. The spacing between the two positioning columns 12 can be adjusted according to the spacing between the two mounting holes 7 on the surface of the door lock 6.

[0030] Furthermore, threaded columns 13 are fixedly connected above the positioning columns 12. When the two positioning columns 12 are inserted into the mounting holes 7, the threaded columns 13 will be exposed from the mounting holes 7. Then, by connecting the locking nuts 14 to the outside of the threaded columns 13 and rotating the locking nuts 14 until they abut against the surface of the door lock 6, the door lock 6 can be quickly fixed.

[0031] At the same time, a second perforation 15 is opened above the lower mold 1. When the punching member 4 moves downward, it will first pass through the first perforation 8 above the door lock 6, and then punch a hole to the bottom of the door lock 6. After punching, it will continue to move downward and enter the second perforation 15.

[0032] For details, please refer to Figure 4 A base 5 is fixedly installed at the bottom of the lower mold 1, and a waste collection box 17 is installed inside the base 5. The waste inside the perforation 15 will enter the waste collection box 17 through the material guide port 16 above the base 5, which is convenient for centralized collection and processing of punching waste.

[0033] Working principle: When using the present invention, the bidirectional screw rod 9 is rotated by rotating the adjusting knob 18, and then the two threaded sleeves 10 connected to the external thread of the bidirectional screw rod 9 move in opposite directions, so that the two positioning columns 12 move in opposite directions. The spacing between the two positioning columns 12 can be adjusted according to the spacing between the two mounting holes 7 on the surface of the door lock catch 6. Threaded columns 13 are fixedly connected above the positioning columns 12. When the two positioning columns 12 are inserted into the mounting holes 7, the threaded columns 13 will be exposed from the mounting holes 7. Then, by connecting the locking nut 14 to the outside of the threaded column 13 and rotating the locking nut 14 until it abuts against the surface of the door lock catch 6, the door lock catch 6 can be quickly fixed.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
