When in use, place the workpiece 260 to be punched on the punching table 240, start the clamping member 250, and make the clamping member 250 press against the workpiece 260 to be punched. According to the need of punching, start the telescopic table 230 to adjust the inclination angle of the workpiece 260 to be punched. Then, according to the need of punching, adjust the movable mounting seat 210, and the punching member 220 to punch, and the punching can be completed. When the workpiece 260 to be punched requires multiple punchings in different directions and angles, the telescopic height of the four telescopic tables 230 can be directly adjusted to freely adjust the direction of the workpiece 260 to be punched, and the infinite direction of inclination rotation can be achieved, so that the sheet metal material can be compressed and freely changed in direction for inclination punching, thereby solving the problem of the prior art that when the same sheet metal material needs to perform multiple inclined punchings in different directions, the sheet metal material needs to be turned to the corresponding direction and then re-compressed and punched, which is very inconvenient and reduces work efficiency.

[0032] Please refer to Figure 3The movable mounting seat 210 includes a fixed seat 211, a first electric push rod 212 and a mounting block 213. The fixed seat 211 is fixedly connected to one side of the top of the support frame 120, the first electric push rod 212 is fixedly connected to the fixed seat 211, and the mounting block 213 is fixedly connected to the output end of the first electric push rod 212. The first electric push rod 212 is started to drive the mounting block 213 to move, thereby driving the punching member 220 to move. The punching member 220 includes a connecting column 221 and a punching rod 222. A moving groove 121 is provided at the top of the support frame 120. One end of the connecting column 221 is fixedly connected to the mounting block 213, and the other end of the connecting column 221 passes through the moving groove 121 and extends into the support frame 120, and the punching rod 222 is fixedly connected to the other end of the connecting column 221. The punching rod 222 is a telescopic punching rod. When started, the punching rod 222 moves toward the punching table 240 to punch the part 260 to be punched.

[0033] In some embodiments, the pressing member 250 includes a second electric push rod 251, a fixed long plate 252 and a pressing plate 253. The second electric push rod 251 is symmetrically connected to the punching table 240.

Start the telescopic cylinder 231 to move the connecting plate 232 up and down, thereby driving the corners of the punching table 240 to tilt. By starting four different telescopic cylinders 231, they move up and down differently, thereby driving the connecting plate 232 to move up and down differently, so that the four corners of the punching table 240 rise and fall to different degrees, so that the punching table 240 is tilted to different angles. According to this phenomenon, the punching table 240 is tilted in a free direction, so that the part to be punched 260 can be tilted in any direction in space.

[0035] Please refer to Figure 5, a circular positioning light 223 is installed on the punching rod 222. The circular positioning light 223 can directly shine on the punching part 260 to be punched, so that the worker can accurately judge the punching hole.

[0036] Please refer to Figure 6 The pressing plate 253 includes a pressing horizontal plate 2531 and a pressing vertical plate 2532. The pressing horizontal plate 2531 is fixedly connected to the lower end of the fixed long plate 252, and the pressing vertical plate 2532 is fixedly connected to the outer side of the pressing horizontal plate 2531. The pressing horizontal plate 2531 is pressed against the top surface of the part to be stamped 260, and the pressing vertical plate 2532 abuts against the side of the part to be stamped 260. The pressing horizontal plate 2531 is used to press the part to be stamped 260, and the pressing vertical plate 2532 abuts against the side of the part to be stamped 260 to prevent the part to be stamped 260 from moving during stamping. A wear-resistant pad 254 is laid on the pressing plate 253. The wear-resistant pad 254 is used to protect the part to be stamped 260 and increase the friction between the part to be stamped 260 and the pressing plate 253.

[0037] Please refer to Figure 7 A collecting groove 270 is provided in the middle of the punching table 240, and a collecting box 280 is placed below the collecting groove 270. When the punching piece 260 is punched, the punching waste falls into the collecting box 280 through the collecting groove 270. A lifting handle 290 is fixedly connected to the side of the collecting box 280. The lifting handle 290 facilitates pulling out the collecting box 280.

[0038] In summary, the working principle of a punching die for sheet metal stamping parts in an embodiment of the utility model is as follows: when in use, the workpiece 260 to be punched is placed on the punching table 240, and the second electric push rod 251 is started to move the fixed long plate 252 toward the punching table 240, so that the clamping plate 253 abuts against the workpiece 260 to be punched, so that the workpiece 260 to be punched is pressed against the punching table 240, and according to the needs of punching, the telescopic cylinder 231 is started to move the connecting plate 232 up and down, thereby driving the corner of the punching table 240 to tilt, and by starting four different telescopic cylinders 231, they are moved up and down differently, thereby driving the connecting plate 232 to move up and down differently, so that the four corners of the punching table 240 rise and fall to different degrees, so that the punching table 240 is tilted to the required angle, and then according to the needs of punching, the telescopic cylinder 231 is started to move the connecting plate 232 up and down differently. When a hole is needed, the first electric push rod 212 is started to drive the mounting block 213 to move, thereby driving the punching rod 222 to move to the corresponding position, and the punching rod 222 punches the hole to complete the punching. When the part 260 to be punched needs multiple punching holes in different directions and angles, the punching table 240 can be tilted to different angles by directly adjusting the telescopic height of the four telescopic cylinders 231, so that the part 260 to be punched can be tilted in any direction in the space, realizing infinite directional inclination rotation, so that the sheet metal material can be pressed while freely changing the direction for tilting and punching, thereby solving the problem of the prior art that when the same sheet metal material needs to be punched with multiple inclined holes in different directions, the sheet metal material needs to be turned to the corresponding direction and then re-pressed and punched, which is very inconvenient and reduces work efficiency.
