Description

Technical Field

A blanking plate 14 matching the lower mold 11 is installed on the upper side of the base 1, and the blanking plate 14 is fixedly installed on the upper side of the plurality of hydraulic rods 13. A lifting plate 15 is slidably assembled on the upper side of the base 1. , a plurality of linearly distributed arc plates 16 are provided on the upper side of the lifting plate 15, and a plurality of suction columns 17 matching the blanking plate 14 are installed on the upper side of the arc plates 16. A circular groove 18 is provided on the upper side of the suction column 17, and a circular hole connected to the circular groove 18 is provided on the lower side of the suction column 17. A top block 19 matching the circular groove 18 is slidably assembled in the suction column 17, and a top rod 20 matching the circular hole is fixed on the lower side of the top block 19. A control component matching the suction column 17 is provided on the upper side of the arc plates 16. A rotating part matching the plurality of arc plates 16 is provided on the upper side of the lifting plate 15, and a lifting part matching the lifting plate 15 is provided on the upper side of the base 1;

[0026] The control assembly includes an annular cavity 25 formed inside the suction column 17. A plurality of positioning holes communicating with the annular cavity 25 are formed on the lower side of the suction column 17. A plurality of positioning rods 26 matching the positioning holes are fixed on the upper side of the arc plate 16. An annular block 27 matching the annular cavity 25 is fixed on the upper side of the plurality of positioning rods 26. A first spring 28 is fixed between the upper side wall of the arc plate 16 and the lower side wall of the suction column 17. The first spring 28 matches the plurality of positioning rods 26.

[0027] The rotating parts include circular shafts 30 fixed to the left and right sides of the arc-shaped plate 16, and gears 31 are concentrically fixed to the circular shafts 30. The left and right sides of the lifting plate 15 are slidably equipped with toothed plates 32 that mesh with the gears 31. The rear sides of the two toothed plates 32 are jointly fixed with a connecting plate 33. The rear side of the lifting plate 15 is equipped with an electric telescopic rod 34, and the output end of the electric telescopic rod 34 is fixedly connected to the connecting plate 33.

[0028] The lifting member includes four support rods 40 fixed on the upper side of the base 1 and distributed symmetrically on the left and right. An elliptical rod 41 is installed between two adjacent support rods 40 for common rotation. The lower side of the elliptical rod 41 is hinged to the upper side of the lifting plate 15. Two vertical rods 42 matching the elliptical rods 41 are fixed on the lower side of the upper mold 10. The vertical rods 42 are hinged to the elliptical rods 41 respectively.

[0029] 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 device;

[0030] When the present invention is used, the user places the plate on the upper side of the lower mold 11, and then starts the hydraulic cylinder 12. The output end of the hydraulic cylinder 12 drives the upper mold 10 to descend, and the upper mold 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 simultaneously drives the plurality of arc plates 16 and the plurality of suction columns 17 to rise, so that the upper side of the suction columns 17 extends out of the upper side of the blanking plate 14. The blanking plate 14 fixes and limits the suction columns 17, thereby ensuring that the suction columns 17 are aligned with the lower mold 11. The upper mold 10 moves downward, causing the plate and the lower mold 11 to descend synchronously, causing the output end of the hydraulic rod 13 to contract. When the lower mold 11 abuts against the blanking plate 14, as the upper mold 10 continues to descend, the plate is punched and cut. The upper mold 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, causing the top block 19 to rise, thereby discharging the air between the top block 19 and the valve plate, forming a negative pressure, so that the valve plate is adsorbed on the suction column 17. On the upper side, the output end of the hydraulic cylinder 12 extends and drives the upper mold 10 to rise. Under the elastic action of the first spring 28, the suction column 17 is reset, and the lifting plate 15 drives the arc 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 downward to separate from the blanking plate 14. Subsequently, the push rod 20 abuts against the base 1. As the lifting plate 15 drives the suction column 17 to descend, the push rod 20 drives the top block 19 to extend upward from the suction column 17, so that the valve plate is separated from the suction column 17. At the same time, the electric telescopic rod 34 The output end of the valve is extended, and the connecting plate 33 drives the two tooth plates 32 to slide synchronously. The tooth plate 32 drives the gear 31 to rotate, and the gear 31 drives the arc plate 16 to rotate. The arc plate 16 drives several suction columns 17 to rotate synchronously. The suction columns 17 drive the ejector rod 20, the ejector block 19 and the valve plate to rotate synchronously, so that the valve plate is separated from the upper side of the suction columns 17 and falls, thereby completing a stamping production process, ensuring the normal discharge of the valve plate after stamping, without manual intervention, and improving the production efficiency of the valve plate.

[0031] Furthermore, a plurality of rotating holes matching the circular shaft 30 are provided on the upper side of the lifting plate 15, thereby limiting the position of the arc plate 16 and ensuring that the arc plate 16 is always in contact with the lifting plate 15, thereby ensuring the smooth stamping production of the valve sheet by the device;

[0032] The present invention drives several suction columns to rise through the lifting plate. When the upper mold and the lower mold punch the plate, the upper mold and the lower mold descend at the same time, so that the suction columns adsorb the stamped valve plate. The lifting part drives the lifting plate to descend, and the valve plate on the upper side of the suction column is ejected by the ejector rod and the ejector block, thereby ensuring the normal collection of the valve plate and improving production efficiency.

[0033] The upper side of the arc-shaped plate 16 is provided with a plurality of elastic members matching the ejector rod 20. The elastic members include a limiting disc 45 fixed to the side wall of the ejector rod 20. A second spring 46 is fixed between the side wall of the limiting disc 45 and the suction column 17.

[0034] During the use of the present invention, when there is no need to discharge, under the elastic action of the second spring 46, the limiting disc 45 is always in contact with the upper side of the arc plate 16, and when the push rod 20 abuts against the base 1 and the valve sheet is ejected from the suction column 17 through the push block 19, the second spring 46 is compressed. As the lifting plate 15 rises, under the elastic action of the second spring 46, the push rod 20 and the push block 19 are reset, thereby ensuring that the push block 19 adsorbs the next batch of valve sheets, thereby ensuring continuous production of the device.

[0035] A plurality of symmetrically distributed guide rods 50 are fixed to the upper side of the base 1. A plurality of third springs 51 matching the guide rods 50 are fixed between the upper side wall of the base 1 and the lower side wall of the lifting plate 15. Round rods 52 are fixed to the upper side of the guide rods 50. The upper mold 10, the lower mold 11 and the blanking plate 14 are all provided with through holes matching the round rods 52.

[0036] During the use of the present invention, the third spring 51 provides support for the lifting plate 15, reducing the supporting strength of the elliptical rod 41 and the vertical rod 42, thereby extending the service life of the device, and the round rod 52 guides the upper mold 10, the lower mold 11 and the blanking plate 14, improving the stamping accuracy of the valve plate and ensuring product quality.

[0037] The upper side of the lifting plate 15 is provided with several arc grooves 55 that match the arc plate 16, and the lifting plate 15 is provided with several discharge ports that match the suction column 17. The upper side of the base 1 is provided with a receiving plate 57 that matches the several discharge ports, and the receiving plate 57 is provided with several elliptical holes 58 that match the ejector rod 20; the arc grooves 55 on the upper side of the lifting plate 15 in the present invention facilitate the rotation of the arc plate 16 to ensure the smooth operation of the device, the receiving plate 57 guides and discharges the fallen valve discs, and the elliptical holes 58 ensure that the ejector rod 20 and the ejector block 19 eject the valve discs uniformly, ensuring the smooth production of the device.

[0038] A hemispherical table 70 is fixed on the lower side of the plurality of push rods 20; when the suction column 17 rotates, the push rod 20 slides more smoothly, avoiding collision damage between the push rod 20 and the base 1, and ensuring the smooth use of the device.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
