[0022] A small-sized shearing machine with high-precision automatic feeding provided by the present utility model, as Figures 1-4 shown, a bracket 3 is installed on a base 2, a hydraulic cylinder 12 is installed on the top of the bracket 3, the hydraulic cylinder 12 is connected to a knife plate 15, guide slideways 25 are respectively installed on the opposite sides of the bracket 3, both sides of the knife plate 15 are respectively located in the two guide slideways 25, and the longitudinal movement of the knife plate 15 along the guide slideways 25 can be realized through the hydraulic cylinder 12 to realize the shearing of the blank plate. The hydraulic cylinder 12 is connected to a small hydraulic station 1. A feed servo motor 8 and a first ball screw guide rail 7 are installed on the base 2. The feed servo motor 8 is connected to the first ball screw guide rail 7. A rotary servo motor 10 is installed on the slider of the first ball screw guide rail 7. The rotary servo motor 10 is connected to a rotary cloud platform 9. An electromagnetic chuck 6 is installed on the rotary cloud platform 9. A photoelectric sensor 11 is installed on the electromagnetic chuck 6. A limit block 5 is installed on the knife plate 15. A guide post 13 is sleeved in the limit block 5. A limit nut 20 is installed at the upper end of the guide post 13. The lower end of the guide post 13 is connected to an auxiliary pressing plate 14. A spring 21 is sleeved on the guide post 13 and between the limit block 5 and the auxiliary pressing plate 14.
[0023] A universal ball platform 16 is installed on the base 2 above the first ball screw guide rail 7. A first guide groove 22 is provided on the universal ball platform 16 above the first ball screw guide rail 7. The electromagnetic chuck 6 is located in the first guide groove 22. A second guide groove 23 is provided on the universal ball platform 16 along the diagonal direction of the universal ball platform 16. A second ball screw guide rail 19 is installed in the second guide groove 23 on the base 2. A positioning servo motor 18 is installed on the base 2. The positioning servo motor 18 is connected to the second ball screw guide rail 19. A positioning block 17 is slidably installed on the second guide groove 23.

[0024] Working principle: Place the blank plate on the universal ball platform 16. When the blank plate moves on the universal ball platform 16, the blank plate moves on the platform through the universal balls, reducing the friction of the blank plate movement. After starting the machine, input the blank plate size and finished product size in the liquid crystal touch screen of the human-machine interaction system 4, and press the OK key. The positioning servo motor 18 drives the second ball screw guide 19 to drive the positioning block 17 to move along the second guide groove 23. The right-angle notch 24 of the positioning block 17 is clamped with the blank plate and then pushes the blank plate to move so that the electromagnetic chuck 6 adsorbs on the central part of the blank plate. The minimum size of the blank plate is 50×50mm, and the maximum size is 600×600mm; the thickness is 0.2 - 3.5mm.

The auxiliary pressing plate 14 first presses on the blank plate, and then the knife plate 15 shears the blank plate. After the shearing is completed, the knife plate 15 and the auxiliary pressing plate 14 are lifted. The rotary servo motor 10 drives the rotary cloud platform 9 to rotate, thereby rotating the blank plate and shearing the next side of the blank plate until all sides of the blank plate are sheared.
