[0012] Furthermore, the linkage rod is in a "U" shape, and a connecting rod is symmetrically provided on the upper part of the recess of the linkage rod. The connecting rod is magnetically connected to the bottom connecting hole of the ejector rod that is slidably connected in the stamping base.

[0013] Furthermore, the top of the stamping top seat is fixedly connected to four connecting hooks in a rectangular array, and the connecting hooks are clamped in the connecting hanging grooves of the upper connecting frame. The bottom and middle of the two ejector rods slidingly connected in the stamping top seat are fixedly connected to the ejector plate, and a return spring is provided on the upper side of the ejector plate in the middle of the ejector rod and connected to the stamping top seat.

Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0029] Example 1: Please refer to Figures 1 to 8 As shown: The present invention provides an intelligent CNC part stamping device, comprising a device base 1, a stamping base 2 is inserted in the upper end surface of the bottom of the device base 1, an ejector rod 3 is symmetrically slidably connected in the top end surface of the stamping base 2, a hydraulic cylinder 6 is fixedly installed on the top of the device base 1, an upper connecting frame 7 is fixedly connected to the bottom of the telescopic end of the hydraulic cylinder 6, a stamping top seat 10 is clamped at the bottom of the upper connecting frame 7, the ejector rod 3 is symmetrically slidably connected in the bottom end surface of the stamping top seat 10, a linkage rod 5 is slidably connected in the middle of the left and right side walls of the upper connecting frame 7, and a limiting component is hinged on the front side wall of the upper connecting frame 7.

[0030] Among them, an inward-concave sliding guide groove 101 is opened in the upper end surface of the bottom of the device base 1, and two connecting sockets 102 are symmetrically opened in the upper end surface of the bottom of the device base 1 on the front and rear sides of the sliding guide groove 101. A mounting seat 103 is fixedly connected to the top of the front side of the rear wall of the device base 1, and a hydraulic cylinder 6 is fixedly installed in the middle of the top end surface of the mounting seat 103.

[0031] Among them, the four end corners of the bottom end face of the stamping base 2 are fixedly connected with connecting rods 201, and the connecting rods 201 are inserted into the connecting sockets 102 of the device base 1. Two inner hidden grooves 202 are symmetrically opened in the top concave end face of the stamping base 2. The upper and lower ends of the slidingly connected ejector rod 3 in the stamping base 2 are fixedly connected with ejector plates 301. The ejector plate 301 at the upper end of the ejector rod 3 is slidably connected in the inner hidden groove 202. A connecting hole 302 is opened in the middle of the bottom end face of the ejector rod 3, and a reset spring 4 is provided on the upper side of the ejector plate 301 at the lower end of the ejector rod 3 and connected to the bottom of the stamping base 2.

[0032] Among them, a hydraulic cylinder 6 is fixedly installed in the middle of the rear side wall of the device base 1, and the telescopic front end of the hydraulic cylinder 6 is fixedly connected to a discharge push plate 601. The discharge push plate 601 is embedded in the middle of the front side of the rear wall of the device base 1, and the discharge push plate 601 is located on the upper side of the stamping base 2.

[0033] By adopting the above technical solution, the connection rod 201 cooperates with the connection socket 102 to realize the rapid installation and disassembly of the stamping base 2 and the device base 1, which is convenient for maintenance or replacement of the stamping base 2. The connection hook 1001 cooperates with the connection hanging groove 701 to realize the rapid connection and disassembly of the stamping top seat 10 and the upper connecting frame 7, which is convenient for replacing different stamping top seats 10 to adapt to different stamping requirements. The linkage rod 5 is connected by magnetic attraction. After the stamping is completed, it rises with the upper connecting frame 7 to drive the ejector rod 3 in the stamping base 2 to move upward synchronously. To achieve automatic ejection of stamped parts, the ejector rod 3 in the stamping ejector seat 10 cooperates with the reset spring 4 to eject the parts after stamping is completed to assist in demoulding. The reset spring 4 at the lower end of the ejector rod 3 in the stamping base 2 automatically resets the ejector rod 3 after completing the ejection action, thereby improving the continuity and efficiency of the stamping operation. The hydraulic cylinder 6 on the rear side wall of the device base 1 drives the discharge push plate 601, which automatically pushes the parts out of the stamping base 2 after the parts are stamped, thereby achieving automatic discharge, reducing manual operation, and avoiding safety hazards of manual material retrieving.

[0034] Among them, two "U"-shaped connecting hanging grooves 701 are symmetrically opened on the front side wall and the front side of the rear wall of the upper connecting frame 7, and sliding ears 702 are provided in the middle of the left and right side walls of the upper connecting frame 7. The sliding ears 702 are slidably connected to the top of the linkage rod 5. Therefore, the connecting hanging grooves 701 are convenient for cooperating with the connecting hooks 1001 of the stamping top seat 10, so as to realize the rapid connection and disassembly of the upper connecting frame 7 and the stamping top seat 10, and facilitate the replacement of different stamping top seats 10 to adapt to different stamping requirements. The sliding connection between the sliding ears 702 and the linkage rod 5 provides guidance and support for the movement of the linkage rod 5, thereby ensuring the stability of the linkage rod 5 during the transmission process.

[0035] Among them, the linkage rod 5 is in a "U" shape, and a connecting rod 501 is symmetrically provided on the upper part of the recess of the linkage rod 5. The connecting rod 501 is magnetically connected to the bottom connecting hole 302 of the ejector rod 3 slidably connected in the stamping base 2. The two top ends of the linkage rod 5 are fixedly connected to the limiting plate 502, and the limiting plate 502 is located on the upper side of the sliding ear 702 of the upper connecting frame 7. Therefore, the linkage rod 5 can be connected by magnetic attraction to drive the ejector rod 3 in the stamping base 2 to move upward synchronously with the rise of the upper connecting frame 7 after the stamping process is completed, thereby realizing the automatic ejection function of the stamping parts in the stamping base 2. The limiting plate 502 limits the movement range of the linkage rod 5 to prevent the linkage rod 5 from disengaging from the sliding ear 702 during movement, and when the upper connecting frame 7 rises, the limiting plate 502 is pressed against the upper side of the sliding ear 702 for follow-up movement, thereby ensuring the stability and reliability of the linkage mechanism.

[0036] By adopting the above technical solution, the sliding ear 702 is slidably connected to the linkage rod 5 to provide guidance and support for the movement of the linkage rod 5, ensuring transmission stability. The limit plate 502 limits the movement range of the linkage rod 5 to prevent it from detaching from the sliding ear 702, thereby ensuring the stability and reliability of the linkage mechanism.

[0037] Among them, a hinge seat 703 is provided on the left side of the front side wall of the upper connecting frame 7, and a locking rod 8 is connected to the hinge seat 703. The bottom of the right end of the locking rod 8 is concave, and a connecting protrusion 704 is provided on the bottom right side of the front side wall of the upper connecting frame 7. The right end of the locking rod 8 matches the connecting protrusion 704, and a fixing pin 9 is inserted at the connection between the right end of the locking rod 8 and the connecting protrusion 704. Therefore, through the cooperation of the locking rod 8, the connecting protrusion 704 and the fixing pin 9, the stamping top seat 10 can be locked and fixed after it is clamped on the upper connecting frame 7, preventing the stamping top seat 10 from loosening or falling off during the stamping process, thereby enhancing the safety and stability of the stamping operation.

[0038] Among them, the top of the stamping top seat 10 is fixedly connected with four connecting hooks 1001 in a rectangular array, and the connecting hooks 1001 are clamped in the connecting hanging groove 701 of the upper connecting frame 7. The bottom and the middle of the two ejector rods 3 slidingly connected in the stamping top seat 10 are fixedly connected with the ejector plate 301. The upper side of the ejector plate 301 in the middle of the ejector rod 3 is provided with a return spring 4 connected to the stamping top seat 10. Therefore, the clamping connection between the connecting hooks 1001 and the connecting hanging groove 701 realizes the rapid installation and disassembly of the stamping top seat 10 and the upper connecting frame 7. The ejector rod 3 in the stamping top seat 10 cooperates with the return spring 4 to perform the ejection operation on the parts after the stamping is completed, assist in completing the demoulding of the parts, and improve the quality and efficiency of part production.

[0039] By adopting the above technical solution, the locking rod 8, the connecting protrusion 704 and the fixing pin 9 cooperate to lock and fix the stamping top seat 10 after it is clamped on the upper connecting frame 7, thereby preventing the stamping top seat 10 from loosening or falling off during the stamping process, thereby enhancing the safety and stability of the stamping operation.

[0040] Specific usage and function of this embodiment: In the present invention, first, the connecting rods 201 at the four end corners of the bottom of the stamping base 2 are correspondingly inserted into the connecting sockets 102 on the upper end surface of the bottom of the device base 1. The stamping base 2 and the device base 1 are quickly installed and fixed by the cooperation of the connecting rods 201 and the connecting sockets 102. If the stamping base 2 needs to be maintained or replaced, it can be pulled out in the reverse direction. Then, the four connecting hooks 1001 distributed in a rectangular array on the top of the stamping top seat 10 are aligned with the "U"-shaped connecting hanging grooves 701 on the front and rear walls of the upper connecting frame 7 and snapped in. Then, through The locking rod 8 on the left hinged seat 703 of the front side wall of the upper connecting frame 7 is buckled with the concave part of its right end on the right connecting protrusion 704, and then the fixing pin 9 is inserted to lock it to prevent the stamping top seat 10 from loosening and falling off during operation. When the device is started, the hydraulic cylinder 6 on the mounting seat 103 on the rear wall of the device base 1 starts to work, and its telescopic end drives the upper connecting frame 7 to move downward, driving the stamping top seat 10 to stamp the parts placed on the stamping base 2. After the stamping is completed, the hydraulic cylinder 6 contracts and drives the upper connecting frame 7 to rise. At this time, the "U"-shaped linkage rod 5 passes through the top limit The positioning plate 502 is pressed against the upper side of the sliding ear 702 and moves with it. The connecting rod 501 in the recess is connected to the connecting hole 302 at the bottom of the ejector rod 3 in the stamping base 2 by magnetic attraction, and the ejector rod 3 is driven to move upward synchronously, so that the ejector plate 301 at the upper end of the ejector rod 3 pops out from the hidden groove 202 in the stamping base 2 to eject the stamped part. At the same time, the ejector rod 3 inside the stamping top seat 10 extends downward under the action of the return spring 4 to further eject the part and assist in demoulding. After the ejection action is completed, the stamping base 2 and the return spring 4 in the stamping top seat 10 respectively push the corresponding ejector The rod 3 is reset to prepare for the next stamping. Finally, the hydraulic cylinder 6 in the middle of the rear side wall of the device base 1 drives the discharge push plate 601 to extend forward, and the parts that have been stamped and ejected are pushed out from the upper surface of the stamping base 2, realizing automatic discharge and avoiding the safety hazards of manual material removal. During the whole process, the linkage rod 5 is guided and supported by the sliding ear 702, and the limit plate 502 limits its range of motion to ensure that the ejection mechanism is stable and reliable, and the quick clamping structure facilitates the replacement of the stamping base 2 and the stamping top seat 10 according to different stamping requirements, thereby improving the practicality and operating efficiency of the device.
