The limiting telescopic sleeve assembly 4 is symmetrically distributed on both sides and its lower end is connected to the top side of the die base 6. This limiting telescopic sleeve assembly 4 is composed of a sleeve, a rod, and a spring. The limiting telescopic sleeve assembly 4 is mainly used for buffering and limiting the pressing die 11 when it is pressed down, thereby improving the stability of the pressing die 11 during the lifting and lowering process. A groove is provided on the top side of the die base 6, and a support spring 15 and a limiting rod 5 are set inside the groove. The inner plate 8 to be pressed is set inside the limiting rod 5. This structure can be pressed down by setting the support spring 15 to avoid collision during the pressing of the pressing die 11. The top of the support spring 15 is fixedly connected to the limiting rod 5. There is one set of limiting rod 5 and support spring 15 on each of the four sides of the punch 10. This structure can be controlled by the limiting rod 5. The inner plate 8 to be stamped is limited to ensure that the position of the inner plate 8 to be stamped does not shift during the pressing of the stamping die 11. A fixing frame 9 is provided at the front end of the die base 6. A slide groove is opened on the fixing frame 9, and a slider 7 is inserted in the slide groove. The top of the slider 7 is connected to the second hydraulic cylinder 3. A diverter pipe 17 is rotatably connected to one end of the slider 7. The diverter pipe 17 is connected to the rotating shaft and the rotating shaft frame and the slider 7. The diverter pipe 17 can be rotated to one side, away from the punch 10 and the stamping die 11, without affecting the stamping operation. The rotation method is manual rotation. In fully automatic equipment, it can be driven by a motor. One end of the diverter pipe 17 is connected to the conveying pipe 13. The conveying pipe 13 can be controlled by installing a valve. A conveying pump 14 is installed on the conveying pipe 13. One end of the 3 is connected to the storage tank 12. This structure can achieve stable adjustment of the height of the diversion pipe 17 by setting the slider 7 and the second hydraulic cylinder 3. By adjusting the height of the diversion pipe 17, it is convenient for the diversion pipe 17 to spray the punch 10 and the stamping die 11 evenly. The punch 10 is fixedly connected to the top of the mold base 6. The stamping die 11 is set on the top of the punch 10. The diversion pipe 17 is set on the fixed frame 9. The second hydraulic cylinder 3 is fixedly connected to the top of the fixed frame 9. One end of the second hydraulic cylinder 3 is connected to the top of the diversion pipe 17. The nozzle 16 is threadedly connected to the outer wall of the diversion pipe 17. One end of the diversion pipe 17 is connected to the storage tank 12. The storage tank 12 stores water-based stamping lubricant. Water-based stamping lubricant has the characteristics of being oil-free and environmentally friendly, and is suitable for stamping metal materials.

[0022] Working principle: When using the inner plate forming mechanism with the convex forming module, the delivery pump 14 is started first. After the delivery pump 14 is started, the lubricant inside the storage tank 12 is input into the distribution pipe 17 through the delivery pipe 13. Then, it is sprayed out from the nozzles 16 at both ends of the distribution pipe 17, and evenly sprayed onto the punch 10 and the stamping die 11. During the spraying process, the second hydraulic cylinder 3 pushes the slider 7 to drive the distribution pipe 17 to slide on the fixed frame 9, thereby adjusting the spraying height of the distribution pipe 17. After the spraying is completed, the inner plate 8 to be stamped is placed on the top of the punch 10 and is located inside the limit rod 5. Then, the first hydraulic cylinder 1 pushes the stamping die 11 down, so that the stamping die 11 contacts the inner plate 8 to be stamped and the punch 10 to achieve stamping.
