A number of suction columns 17 matching the blanking plate 14 are installed on the upper sides of the arc-shaped plates 16. Circular grooves 18 are provided on the upper sides of the suction columns 17, and circular holes communicating with the circular grooves 18 are provided on the lower sides of the suction columns 17. A top block 19 matching the circular groove 18 is slidably assembled in the suction column 17. A top rod 20 matching the circular hole is fixedly provided on the lower side of the top block 19. Control components matching the suction columns 17 are provided on the upper sides of the arc-shaped plates 16. A rotating member matching the number of arc-shaped plates 16 is provided on the upper side of the lifting plate 15. A lifting member matching the lifting plate 15 is provided on the upper side of the base 1; The control component includes an annular cavity 25 provided inside the suction column 17. A number of positioning holes communicating with the annular cavity 25 are provided on the lower side of the suction column 17. A number of positioning rods 26 matching the positioning holes are fixedly provided on the upper side of the arc-shaped plate 16. An annular block 27 matching the annular cavity 25 is fixedly provided on the upper sides of the number of positioning rods 26 together. A first spring 28 is fixedly provided between the upper side wall of the arc-shaped plate 16 and the lower side wall of the suction column 17, and the first spring 28 matches the number of positioning rods 26; The rotating member includes a circular shaft 30 fixedly provided on the left and right sides of the arc-shaped plate 16. A gear 31 is concentrically fixedly provided on the circular shaft 30. A toothed plate 32 meshing with the number of gears 31 is slidably assembled on the left and right sides of the lifting plate 15. A connecting plate 33 is fixedly provided on the rear sides of the two toothed plates 32 together. An electric telescopic rod 34 is installed on the rear side of the lifting plate 15, and the output end of the electric telescopic rod 34 is fixedly connected to the connecting plate 33; The lifting member includes four support rods 40 fixedly provided on the upper side of the base 1 and distributed symmetrically left and right. An elliptical rod 41 is rotatably assembled between two adjacent support rods 40. The lower side of the elliptical rod 41 and the upper side of the lifting plate 15 are hinged to each other. Two vertical rods 42 matching the elliptical rod 41 are fixedly provided on the lower side of the upper die 10, and the vertical rods 42 are respectively hinged to the elliptical rod 41; In the present invention, a sealing member is provided on the side wall of the top block 19 to ensure the adsorption of the top block 19 to the valve plate, thereby ensuring the smooth use of the present device; When the present invention is applied, the user places the plate on the upper side of the lower die 11, and then starts the hydraulic cylinder 12. The output end of the hydraulic cylinder 12 drives the upper die 10 to descend. The upper die 10 drives the elliptical rod 41 to rotate through the vertical rod 42. The elliptical rod 41 drives the lifting plate 15 to rise. The lifting plate 15 synchronously drives a plurality of arc-shaped plates 16 and a plurality of suction columns 17 to rise, so that the upper side of the suction column 17 extends out of the upper side of the blanking plate 14. The blanking plate 14 fixes and limits the suction column 17, thereby ensuring that the suction column 17 is aligned with the lower die 11. The upper die 10 moves downward, causing the plate and the lower die 11 to descend synchronously, and causing the output end of the hydraulic rod 13 to contract. When the lower die 11 abuts against the blanking plate 14, as the upper die 10 continues to descend, the plate is stamped and cut. The upper die 10 drives the valve plate to descend, causing the valve plate to abut against the upper side of the suction column 17, causing the suction column 17 to descend, causing the first spring 28 to contract, and causing the top block 19 to rise, thereby discharging the air between the top block 19 and the valve plate to form a negative pressure, so that the valve plate is adsorbed on the upper side of the suction column 17. The output end of the hydraulic cylinder 12 extends to drive the upper die 10 to rise. Under the elastic action of the first spring 28, the suction column 17 is reset. The lifting plate 15 drives the arc-shaped plate 16 and the suction column 17 to descend. As the output end of the hydraulic cylinder 12 extends, the suction column 17 drives the valve plate to disengage from the blanking plate 14 downward. Subsequently, the ejector rod 20 abuts against the base 1. As the lifting plate 15 drives the suction column 17 to descend, the ejector rod 20 drives the top block 19 to extend upward out of the suction column 17, causing the valve plate to disengage from the suction column 17. At the same time, the output end of the electric telescopic rod 34 extends, driving the two rack plates 32 to slide synchronously through the connecting plate 33. The rack plate 32 drives the gear 31 to rotate. The gear 31 drives the arc-shaped plate 16 to rotate. The arc-shaped plate 16 drives a plurality of suction columns 17 to rotate synchronously. The suction column 17 drives the ejector rod 20, the top block 19 and the valve plate to rotate synchronously, so that the valve plate disengages from the upper side of the suction column 17 and drops, thus completing a stamping production process, ensuring the normal discharging of the valve plate after stamping, without manual intervention, and improving the production efficiency of the valve plate; Further, a plurality of rotation holes matching the round shaft 30 are formed on the upper side of the lifting plate 15, so as to limit the arc-shaped plate 16 and ensure that the arc-shaped plate 16 always fits with the lifting plate 15, thereby ensuring the smooth stamping production of the valve plate by the present device; The present invention drives a plurality of suction columns to rise through the lifting plate. When the upper die and the lower die stamp the plate, the upper die and the lower die descend simultaneously, so that the suction column adsorbs the stamped valve plate. The lifting member drives the lifting plate to descend, and the valve plate on the upper side of the suction column is ejected through the ejector rod and the top block, thereby ensuring the normal collection of the valve plate and improving the production efficiency.

[0018] On the upper side of the arc-shaped plate 16, a number of elastic members matching the ejector rods 20 are provided. The elastic members include a limit disc 45 fixedly arranged on the side wall of the ejector rod 20, and a second spring 46 is fixedly arranged between the side wall of the limit disc 45 and the material suction column 17; During the use of the present invention, when there is no need to discharge materials, under the elastic action of the second spring 46, the limit disc 45 is always in contact with the upper side of the arc-shaped plate 16. When the ejector rod 20 abuts against the base 1 and the valve plate is pushed out by the top block 19 to be separated from the material suction column 17, the second spring 46 is compressed. As the lifting plate 15 rises, under the elastic action of the second spring 46, the ejector rod 20 and the top block 19 are reset, so as to ensure that the top block 19 adsorbs the next batch of valve plates, thus ensuring the continuous production of the device.

[0019] On the upper side of the base 1, a number of symmetrically distributed guide rods 50 are fixedly arranged. A number of third springs 51 matching the guide rods 50 are fixedly arranged between the upper side wall of the base 1 and the lower side wall of the lifting plate 15. Round rods 52 are fixedly arranged on the upper sides of the guide rods 50, and the upper die 10, the lower die 11 and the blanking plate 14 are all provided with through holes matching the round rods 52; During the use of the present invention, the third spring 51 provides support for the lifting plate 15, reducing the support strength of the elliptical rod 41 and the vertical rod 42, thereby prolonging the service life of the device. And the round rod 52 guides the upper die 10, the lower die 11 and the blanking plate 14, improving the stamping accuracy of the valve plate and ensuring the product quality.

[0020] On the upper side of the lifting plate 15, a number of arc-shaped grooves 55 matching the arc-shaped plate 16 are opened. The lifting plate 15 is provided with a number of blanking ports matching the material suction column 17. On the upper side of the base 1, a receiving plate 57 matching the number of blanking ports is provided. The receiving plate 57 is provided with a number of elliptical holes 58 matching the ejector rods 20; In the present invention, the arc-shaped grooves 55 on the upper side of the lifting plate 15 facilitate the rotation of the arc-shaped plate 16, ensuring the smooth operation of the device. The receiving plate 57 guides and discharges the dropped valve plates, and the elliptical holes 58 ensure that the ejector rods 20 and the top blocks 19 eject the valve plates uniformly, ensuring the smooth production of the device.

[0021] Hemispherical platforms 70 are fixedly arranged on the lower sides of a number of ejector rods 20; When the material suction column 17 rotates, the sliding of the ejector rod 20 is smoother, avoiding the collision and damage between the ejector rod 20 and the base 1, and ensuring the smooth use of the device.

[0022] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
