Example four

A stamping method based on a medium-pressure die device in the third embodiment is different from the stamping method in the second embodiment in that:

in the first step, the feeding vibration tray 14 conveys the raw material 20 to the conveying rail 15 in order, and when the raw material 20 reaches the second discharging through hole of the conveying rail 15, the raw material 20 falls into the charging barrel 16. The fourth driving device 17 drives the discharging barrel 16 to move between the pressing cavity 5 and the pressing rod 23, and then drives the discharging barrel 16 to move downwards. After the base of the discharge barrel 16 enters the flange member 18, the arcuate blades 1315 of the rotating shutter base 1614 open toward the rotating disc 1611 to deliver the feedstock 20 into the die cavity 5. The second driving device 22 drives the mounting plate 21 to move towards the lower molding die 3, and the press rod 23 extends into the compression cavity 5 to press the raw material 20.

And step two, after the raw materials 20 are pressed into a product, the second driving device 22 drives the mounting plate 21 to reset, so that the compression bar 23 extends out of the pressing cavity 5. The charging barrel 16 is reset to the lower end of the second discharging through hole of the conveying guide rail 15. The first driving device 4 drives the lower forming die 3 to move horizontally, so that the die cavity 5 located on the pressing area 12 moves to the discharging area 11, and the die cavity 5 located on the discharging area 11 moves to the pressing area 12.

And step three, after the charging barrel 16 conveys the new raw material 20 into the compression cavity 5 on the compression area 12 again, the second driving device 22 drives the mounting plate 21 to move towards the lower molding die 3, the pressing rod 23 and the push rod 24 simultaneously extend into the corresponding compression cavity 5, and the pressing rod 23 presses the raw material 20. The push rod 24 pushes the product pressed and formed in the step two out of the through hole and enters the discharging channel 7, and the third driving device 21 of the discharging device 26 drives the second push rod 22 to push the formed product out of the discharging channel 7.

And step four, after the raw material 20 in the step three is pressed into a product, resetting the output end of the first driving device 4, so that the compression cavity 5 positioned on the discharging area 11 moves to the pressing area 12, the compression cavity 5 positioned on the pressing area 12 moves to the discharging area 11, and then starting the operation of the step two.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
