The handle 20 is fixed on one end of the rotating shaft 17 extending to the outside of the base 1. When in use, the operator drives the rotating shaft 17 by rotating the handle 20 according to the size of the mold 9, thereby driving the worm 18 to rotate and drive the slide 6 to adjust the angle, so that the angle between the inclined wall of the mold 9 and the stamping mold 9 assembly meets the needs of the stamping work.

[0026] The punching seat 7 is tilted and fixed on the slide 6 and is located directly below the punching die 9. A through hole 21 is opened on the punching seat 7, and a bearing 22 is arranged in the through hole 21. A connecting shaft 23 is fixed on the turntable 8, and the connecting shaft 23 is inserted into the bearing 22; a groove is opened on the slide 6 and located below the punching seat 7, and the driving assembly includes a servo motor 24, a driving wheel 25 and a driven wheel 26.

A plurality of mounting holes 31 are provided in a circular shape at the upper edge of the mold 9, and the mold 9 and the T-slots 30 are fixedly connected by bolts and nuts. When in use, the operator first puts the bolts into the corresponding positions in the T-slots 30 according to the size of the mold 9, then puts the mold 9 on the rotating disk and passes the bolts through the mounting holes 31 of the mold 9, and finally screws the nuts on the bolts to fix the mold 9.

[0029] Working principle of the present invention:

[0030] When in use, the operator selects the corresponding mold 9 according to the pot rack that needs to be patterned, and puts bolts into the corresponding number of T-slots 30 on the turntable 8 according to the number of mounting holes 31 on the mold 9, then places the mold 9 on the turntable 8 and inserts multiple bolts into the corresponding mounting holes 31, and finally screws nuts on the multiple bolts to fix the mold 9.

[0031] After fixing the mold 9, the operator sets the parameters of the frequency, time and start-stop interval of the servo motor 24, and the start-stop time interval of the cylinder 15 on the PLC module of the control box 12, and then places the basin stand on the mold 9, and starts the drive motor 10 through the control box 12 to start the pattern making work.

[0032] After the driving motor 10 is started, it drives the synchronous belt 11 to rotate. The cylinder 15 retracts through the setting parameters of the PLC module to pull the pull rod 14 downward to drive the clutch device 13, so that the synchronous belt 11 drives the rotating shaft 17 to rotate. The rotating shaft 17 rotates to drive the stamping die 4 to move downward along the guide block 5 to stamp the basin frame to complete a pattern punching work. When the stamping die 4 moves upward, the servo motor 24 starts to drive the mold 9 through the parameters set by the PLC module to drive the basin frame to rotate one grid, and then the servo motor 24 stops. After the crankshaft 3 rotates one circle, the stamping die 4 moves downward again, so that the work of punching multiple pattern gears on the basin frame can be automatically performed. After the stamping of multiple pattern gears on the basin frame is completed, the cylinder 15 extends out to push the pull rod 14 to drive the clutch device 13 again, so that the clutch device 13 clamps the crankshaft 3, which is convenient for the operator to replace the basin frame.

Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.
