[0022] In a preferred embodiment, the top of the cutting frame 1 is provided with a sliding groove 22, and the inner wall of the sliding groove 22 is slidably connected with the side of the sliding block 9. Through the provision of the sliding groove 22, the number of the sliding grooves 22 is four, and the four sliding grooves 22 are all provided on the top of the cutting frame 1, so that the inner walls of the four sliding grooves 22 assist in limiting the movement path of the four sliding blocks 9.

[0023] In a preferred embodiment, a spring 10 is fixedly connected to the bottom of the inner wall of the slider 9, and the top of the spring 10 is fixedly connected to the bottom of the round rod 11. A top plate 17 is fixedly mounted on the top of the round rod 11, and a positioning plate 18 is fixedly mounted on the bottom of the top plate 17. A rubber pad 19 is fixedly mounted on the bottom of the positioning plate 18. Through the cooperation of the spring 10 and the round rod 11, the spring 10 pushes the round rod 11 upward in the inner wall of the slider 9, thereby driving the top plate 17 upward, and the top plate 17 drives the rubber pad 19 upward through the positioning plate 18, thereby assisting the top of the metal material to separate from the rubber pad 19, and assisting the stable removal and placement of the metal material.

[0024] In a preferred embodiment, a connecting pipe 12 is fixedly sleeved on the inner wall of the slider 9, and a solenoid valve air inlet pipe 13 is fixedly sleeved on the inner wall of the connecting pipe 12.

An air extraction pump 16 is fixedly mounted on the side of the cutting frame 1, and the air extraction port of the air extraction pump 16 is fixedly sleeved on the inner wall of the air extraction pipe 15. Through the cooperation of the connecting pipe 12 and the solenoid valve air inlet pipe 13, the air extraction pump 16 is used to stably extract the gas inside the slider 9 by using the connecting pipe 12, the exhaust pipe 14 and the air extraction pipe 15 to assist the air extraction pump 16. Air is introduced into the connecting pipe 12 by the solenoid valve air inlet pipe 13, thereby supplying air to the inside of the slider 9. The auxiliary round rod 11 moves upward and resets under the push of the spring 10.

[0025] In a preferred embodiment, a transmission belt 21 is movably sleeved on the outer edge of the drive wheel 4, and a transmission wheel 20 is movably sleeved on the inner wall of the transmission belt 21. The side of the transmission wheel 20 is rotatably connected to the side of the cutting frame 1.

There are four sliders 9, and the inner walls of the four sliders 9 are threadedly connected to the outer edges of the two positive thread rods 6 and the two negative thread rods 8, respectively. With the addition of the four sliders 9, the four sliders 9 move in opposite directions in pairs under the rotation of the two positive thread rods 6 and the negative thread rods 8, thereby driving the two positioning plates 18 to move, which is convenient for adjustment according to the size of the metal raw material.

[0027] Working principle: When the device is in use, the motor 3 drives the drive wheel 4 to rotate, which in turn drives the transmission wheel 20 to rotate via the transmission belt 21. The transmission wheel 20 and the drive wheel 4 then drive the two positive thread rods 6 and the two negative thread rods 8 to rotate, thereby causing the four sliders 9 to move towards each other. The four sliders 9 also drive the two positioning plates 18 to move towards each other, thus facilitating adaptive adjustment according to the size of the metal material. After that, the solenoid valve air inlet pipe 13 is closed, and the air pump 16 guides the gas inside the slider 9 to be discharged through the air extraction pipe 15 and the exhaust pipe 14 auxiliary connecting pipe 12, thereby assisting the round rod 11 to move down on the inner wall of the slider 9. The round rod 11 then drives the positioning plate 18 to move down via the top plate 17, and the positioning plate 18 drives the rubber pad 19 to stably clamp the metal material. By opening the solenoid valve air inlet pipe 13, the solenoid valve air inlet pipe 13 assists in the intake of air into the slider 9, and the spring 10 pushes the round rod 11 up, thus facilitating the placement and removal of the metal material.
