[0026] The clamping mechanism 2, the number of the clamping mechanisms 2 is two groups. The clamping mechanism 2 includes a square base 24 fixed on the workbench 1 and a cylinder 25 fixed inside the workbench 1. The number of the square bases 24 is four, and the front and rear two square bases 24 are in a group. A first piston 23 is movably connected inside the square base 24. A piston rod 22 is fixed on the side of the first piston 23. A chuck 21 for clamping a blank is fixed at the end of the piston rod 22. The piston rod 22 is used for connecting and fixing the chuck 21 and the first piston 23. Each group of the clamping mechanisms 2 has two chucks 21 aligned front and back. A second piston 26 is movably connected inside the cylinder 25. The cylinder 25 is communicated with the square base 24, and hydraulic oil is filled in both the cylinder 25 and the square base 24. The hydraulic oil is filled between the first piston 23 and the second piston 26. A connecting rod 27 that moves up and down along the inner wall of the cylinder 25 is fixed at the bottom of the second piston 26. A square bar 28 is fixed at the bottom of the connecting rod 27. A driving member 29 is fixed at the top of the inner wall of the workbench 1. The square bar 28 is used for connecting and fixing two connecting rods 27 on the same side. The square bar 28 is fixedly connected to the telescopic end of the driving member 29. The driving member 29 can be a hydraulic cylinder or an electric push rod;

[0027] The cutting saw blade 3. There is a notch at the position corresponding to the cutting saw blade 3 on the workbench 1. A lifting assembly 5 is arranged on the square base 24. The lifting assembly 5 is used to drive the motor 4 and the cutting saw blade 3 to move up and down. The workbench 1 is connected with a motor 4 through the lifting assembly 5. The cutting saw blade 3 is fixed at the output end of the motor 4.

[0028] Specifically, a guide post 6 is fixed on the side of the chuck 21. The guide post 6 is slidably connected with the inner wall of the guide groove opened on the side of the square base 24.

[0029] In this embodiment, please refer to Figure 5 . When the chuck 21 moves, it drives the guide post 6 to move along the inner wall of the guide groove. The guide post 6 guides the chuck 21 to make the movement of the chuck 21 smoother and more stable.

[0030] Specifically, the guide post 6 is circular and parallel to the piston rod 22.

[0031] In this embodiment, please refer to Figure 4 . The guide post 6 is parallel to the piston rod 22, so as to prevent the guide post 6 from affecting the normal movement of the chuck 21.

[0032] Specifically, a recessed portion is arranged on the surface of the guide post 6, and a protruding portion is arranged at the position corresponding to the recessed portion in the guide groove opened on the side of the square base 24.

[0033] In this embodiment, please refer to Figure 4 . The recessed portion fits with the protruding portion to improve the guiding ability of the guide groove for the guide post 6, and thus improve the guiding ability for the chuck 21.

[0034] Specifically, a rubber pad 7 is fixed on the surface of the chuck 21 to stably clamp the blank.

[0035] In this embodiment, please refer to Figure 2 , the rubber pad 7 is used to increase the friction between the blank and the chuck 21, so as to stably clamp the blank.

[0036] Specifically, the lifting assembly 5 includes a bracket 51 fixed on the square seat 24 and a hydraulic cylinder 52 fixed on the bracket 51. A square block 54 is fixed at the telescopic end of the hydraulic cylinder 52. The square block 54 is fixed at the bottom feet of the motor 4, and a slider 53 that moves up and down along the inner wall of the bracket 51 is fixed on the side of the square block 54.

[0037] In this embodiment, please refer to Figure 1 and Figure 3 , the bracket 51 is used to fix the hydraulic cylinder 52. After the hydraulic cylinder 52 is started, it drives the slider 53 and the motor 4 to move downward through the square block 54, and the motor 4 drives the rotating cutting saw blade 3 to move downward to cut the blank.

[0038] Specifically, the slider 53 is in an isosceles trapezoid shape to improve the guiding ability for the motor 4.

[0039] In this embodiment, please refer to Figure 3 , the isosceles trapezoid-shaped slider 53 is used to prevent itself from separating from the bracket 51 and can improve the guiding ability for the square block 54, thereby improving the guiding ability for the motor 4.

[0040] The working principle and usage process of the present utility model: Place the blank between the front and rear chucks 21, start the driving member 29 to make the square bar 28 drive the connecting rod 27 to move upward, the connecting rod 27 drives the piston two 26 to move upward along the inner wall of the cylinder 25 and squeeze the hydraulic oil, so that the hydraulic oil drives the piston one 23 to move, and the piston one 23 drives the piston rod 22 to move, thereby driving the front and rear chucks 21 to clamp each other to clamp the blank;

[0041] After the clamping is completed, start the motor 4 to make the motor 4 drive the cutting saw blade 3 to rotate at a high speed, and then start the hydraulic cylinder 52 to make the piston rod 22 of the hydraulic cylinder 52 drive the square block 54 to move downward. The square block 54 drives the slider 53 to move downward along the inner wall of the bracket 51 and drives the motor 4 to move downward at the same time. The motor 4 drives the rotating cutting saw blade 3 to move downward to cut the blank;

[0042] After cutting is completed, the hydraulic cylinder 52 drives the motor 4 and the cutting saw blade 3 to move upward. After the cutting saw blade 3 is separated from the blank, the motor 4 can be turned off. Then, the piston rod 22 of the driving member 29 extends to drive the square bar 28 to move downward. The square bar 28 drives the second piston 26 to move downward through the connecting rod 27. The second piston 26 no longer presses the hydraulic oil and forms a negative pressure inside the cylinder 25 and the square seat 24. The chuck 21 moves reversely under the action of the external atmospheric pressure and is separated from the blank. After separation, the blank can be removed from the workbench 1.
