DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0032] Example

[0033] First, a cutting box 2 is constructed. An observation window with soundproof glass is provided on the side of the cutting box 2. This glass reduces noise levels and protects the operator's hearing. A loading and unloading port is located at one end of the cutting box, and a closed door 1 is installed at the port to ensure a closed and safe metal cutting process. An inclined guide plate 21 is installed at the bottom of the cutting box 2. The end of the guide plate 21 is connected to a waste outlet, which is connected to a waste storage bin 23 for convenient waste collection and storage.

[0034] Slide rails 19 are fixed on both sides of the cutting box 2, and a material loading plate 6 is slidably connected to the slide rails 19. A plurality of clamps 7 for fixing materials are installed on the material loading plate 6, thereby ensuring the stability and cutting accuracy of the material during the cutting process.

[0035] A cutting wheel 9 is secured to the inside of the cutting box 2 by a mounting bracket 10. A gravity sensor is located between the mounting bracket 10 and the cutting box 2. This gravity sensor monitors the force exerted by the material on the cutting wheel during cutting, adjusting the material's feed rate based on the force exerted on the wheel. This increases the wheel's service life and ensures cutting efficiency while preventing excessive force from causing an uneven cut surface.

[0036] An adjustment device is provided below the cutting wheel 9 for adjusting the advancement speed of the carrier plate 6. The adjustment device includes a stop plate 18, a connecting rod 17 of which extends into the adjustment chamber 11 and is fixedly connected to the push block 16. The adjustment chamber 11 contains a non-Newtonian fluid and includes a horizontal cavity 13 and a vertical cavity 12. An adjustment switch is provided between the horizontal cavity 13 and the vertical cavity 12. The adjustment switch includes a chute, in which a baffle 15 is slidably connected. One end of the baffle 15 is fixedly connected to the end of the chute via a spring. An electromagnet 4 is fixed to the upper portion of the adjustment chamber 11. A magnetic block is provided on the baffle 15 relative to the electromagnet 4. A strip groove is provided on the upper portion of the adjustment chamber 11 for the magnetic block to slide. A return spring is fixed between the push block 16 and the inner wall of the adjustment chamber 11 near one end of the stop block. The return spring can automatically return the push block 16 to its original position when no external force is applied.

[0037] Positioning members are fixed on both sides of the cutting box 2 to limit the advance distance of the carrier plate 6. These positioning members comprise a threaded sleeve 22 fixed to the sidewall of the cutting box 2. A threaded tube 4 is rotatably connected to the sleeve 22. An operating disk 3 is fixed to the front end of the threaded tube 4, and a position-limiting disc 20 is fixed to the rear end of the threaded tube 4. The position of the position-limiting disc 20 can be adjusted using the operating disk 3, thereby controlling the advance distance of the carrier plate 6.

[0038] The fixture 7 includes a movable base, atop which is secured a first gas cylinder 701. Inside the first gas cylinder 701 is a piston and a piston rod extending vertically downward, the end of which is connected to a pressure plate 702. A spring is positioned between the piston and the lower portion of the first gas cylinder 701. A first one-way valve 703 is positioned at the top of the first gas cylinder 701, along with multiple second one-way valves 704 positioned on its sidewalls. A third one-way valve 705 is positioned at its lower end. The loading plate is driven back and forth by the second gas cylinder 5. A fourth one-way valve 501 and a pressure relief valve 504 are positioned at the end of the second gas cylinder 5 away from the output rod. A fifth one-way valve 502 is positioned on its sidewalls. The fourth one-way valve 501 is connected to the second one-way valve 704, while the fifth one-way valve 502 is connected to the fourth one-way valve 501. A sixth one-way valve 503 is positioned at the end of the second gas cylinder 5 near the output rod.

[0039] The first one-way valve 703 and the sixth one-way valve 503 are connected to the gas outlet pipe of the gas generating device.

[0040] The gravity sensor is connected to the controller, the electromagnet 4 is connected to the controller, and the gas generator is connected to the controller. The controller is responsible for regulating the operation of each component to ensure the efficiency and accuracy of the entire metal cutting production system.

[0041] The cutting path of the carrier plate 6 is provided with a hollow structure, within which a motor-driven fan blade 8 is mounted. The top and bottom of the hollow structure are provided with leak holes. The fan blade 8 exhausts air from top to bottom, helping to dissipate heat generated during the metal cutting process. The negative pressure also facilitates chip removal, and the wind force further blows the waste into the waste storage bin 23, thus ensuring stable operation and cutting quality of the metal cutting production system.

[0042] The working principle of this application is:

[0043] After the material is manually positioned on the carrier plate 6, the gas generating device is started, the controller first connects the first one-way valve 703, and the output shaft of the first gas cylinder 701 extends downward. When the piston moves to the preset second one-way valve 704, the elastic telescopic rod is in a compressed state, and the pressure plate 702 is pressed on the material to fix the material, and the pressure force of the pressure plate 702 is the weight of the pressure plate 702 and the elastic force of the elastic telescopic rod; the gas is discharged from the second one-way valve 704, and the gas enters the second gas cylinder 5 through the fourth one-way valve 501, thereby driving the output shaft of the second gas cylinder 5 to extend, thereby pushing the carrier plate 6 to move toward the cutting wheel 9, so that the material is cut;

[0044] During the cutting process, when the material contacts the cutting wheel 9, the air pressure in the second air cylinder 5 remains constant, and excess pressure is released through the pressure relief valve 504. A pressure sensor is installed in the second air cylinder 5 to monitor the pressure in real time. The sensor transmits pressure data to the control system, allowing for real-time adjustments to the pumping and pressure relief rates. The controller receives the data from the pressure sensor and adjusts the pumping and pressure relief rates based on a preset pressure range. This can be a microcontroller, PLC, or computer control system.

[0045] Under the action of constant pressure, the material plate is pushed forward, and the material carrier plate 6 contacts the abutment plate 18. In the process of pushing the abutment plate 18, the force of the non-Newtonian fluid needs to be overcome. The elastic coefficient of the spring is small compared to the non-Newtonian fluid and can be ignored. The force of the cutting wheel 9 changes the magnetic force of the electromagnet 14, thereby changing the passage openings of the vertical cavity 12 and the horizontal cavity 13, thereby changing the flow rate of the non-Newtonian fluid flowing upward, thereby fine-tuning the propulsion speed of the material carrier plate 6, so that the force of the cutting wheel 9 is within an acceptable range;

[0046] After the cutting is completed, the controller controls the disconnection of the air intake of the first one-way valve 703, and instead supplies air to the sixth one-way valve 503 to drive the piston of the second air cylinder 5 to retreat, and at the same time, the air is pumped out and the pressure is relieved through the pressure relief valve 504. When the piston of the second air cylinder 5 retreats to the end, the pressure relief valve 504 is closed, and part of the gas enters the first air cylinder 701 through the fifth one-way valve 502 and the third one-way valve 705. The piston in the first air cylinder 701 returns to its position, thereby fixing the material with the contact clamp 7.

All technical solutions based on the concept of the present invention are within the scope of protection of the present invention.
