[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This hardware workpiece cutting device with stable clamping function is equipped with a cutting machine, a dust extraction fan, a protective shell, and a dust extraction frame. The dust extraction frame is set on both sides of the protective shell, so that when the cutting machine moves, the protective shell can move the dust extraction frame along with the cutting machine.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a hardware workpiece cutting device with stable clamping function, including a processing table 1, with mounting plates 2 symmetrically fixedly connected to the top of the processing table 1, and an electric telescopic rod 3 installed on one side of each mounting plate 2. By setting the electric telescopic rod 3, the electric telescopic rod 3 drives the movable frame 4 to move, so that the movable frame 4 can abut against both sides of hardware workpieces of different specifications, thereby achieving clamping and fixing of hardware workpieces of different specifications and improving the practicality of the device. One end of the electric telescopic rod 3 passes through the mounting plate 2 and is provided with a movable frame 4. The inner wall of the movable frame 4 is rotatably connected to a bidirectional threaded rod 5 via a bearing. Both ends of the bidirectional threaded rod 5 pass through the movable frame 4 and are fixedly connected to knobs 6. By setting the bidirectional threaded rod 5, the rotation of the bidirectional threaded rod 5 can drive the movable block 7 outside the bidirectional threaded rod 5 to move synchronously, so that the movable block 7 can drive the clamping plate 9 to clamp the hardware workpiece. The bidirectional threaded rod 5 is symmetrically threaded inside the movable frame 4 and connected to the movable block 7. The movable block 7 is slidably connected to the inner wall of the movable frame 4. Each movable block 7 has a limit block 8 fixedly connected to its upper and lower sides. The limit block 8 is slidably connected to the inner wall of the movable frame 4. A clamping plate 9 is fixedly connected to one side of the movable block 7 through the movable frame 4. By setting the limit block 8, the limit block 8 can move together with the movable block 7, so that the movable block 7 can drive the limit block 8 to slide inside the movable frame 4, thereby allowing the movable frame 4 to limit the movable block 7 through the limit block 8. The movable frame 4 is fixedly connected to the limit slide rods 10 on both sides of the electric telescopic rod 3. The limit slide rods 10 are slidably connected to the mounting plate 2. By setting the limit slide rods 10, when the electric telescopic rod 3 drives the movable frame 4 to move, the movable frame 4 can drive the limit slide rods 10 to slide within the mounting plate 2, so that the mounting plate 2 can limit the movable frame 4 through the limit slide rods 10, making the movement of the movable frame 4 more stable. A support frame 11 is fixedly installed in the middle of both sides of the processing table 1. A motor 12 is fixedly connected to the top of one side of the support frame 11. A movable threaded rod 13 is installed on one side of the motor 12 through the output shaft. The movable threaded rod 13 is rotatably connected to the inner wall of the support frame 11 through a bearing. A slider 14 is threadedly connected to the outside of the movable threaded rod 13. Connecting plates 15 are fixedly connected to both sides of the slider 14. The connecting plates 15 are slidably connected to the inner wall of the support frame 11. By setting the movable threaded rod 13, the motor 12 drives the movable threaded rod 13 to rotate through the output shaft, so that the movable threaded rod 13 drives the slider 14 to slide inside the support frame 11. This allows the slider 14 to drive the electric push rod 16 and the cutting machine 18 to move, so that the cutting machine 18 can perform cutting processing on the hardware workpiece. An electric push rod 16 is fixedly connected to the bottom of the slider 14. A lifting block 17 is installed at the bottom of the electric push rod 16. A cutting machine 18 is fixedly connected to the bottom of the lifting block 17. A protective shell 19 is installed on one side of the lifting block 17. The protective shell 19 is positioned corresponding to the cutting machine 18. Two dust collection frames 20 are fixed on both sides of the protective shell 19. The same hose 21 is installed on the top of the four dust collection frames 20. A dust collection fan 22 is installed on the top of the hose 21. By setting the electric push rod 16, the electric push rod 16 drives the lifting block 17 to move up and down. The lifting block 17 drives the cutting machine 18 and the protective shell 19 to move together, so that the cutting machine 18 can move to the top of the hardware workpiece and cut the hardware workpiece. A waste bin 23 is installed on one side of the vacuum fan 22. The waste bin 23 is fixedly connected to the top of the support frame 11. A collection box 24 is movably connected through the inside of the waste bin 23. The top of the vacuum fan 22 passes through the waste bin 23 and is connected to the inner wall of the collection box 24. By setting up the collection box 24, the collection box 24 can collect the dust and waste in a unified manner, which facilitates the unified treatment of the dust and waste.
[0014] The working principle of this utility model is as follows: In use, place the metal workpiece between the movable frames 4, activate the electric telescopic rod 3, which moves the movable frame 4 toward the metal workpiece until it abuts against both sides of the workpiece. Then, turn the knob 6, which rotates the bidirectional threaded rod 5 inside the movable frame 4. The bidirectional threaded rod 5 moves the movable block 7 relative to the workpiece, causing the movable block 7 to move the clamping plate 9 against the surface of the workpiece, thus clamping and fixing the workpiece. Activate the electric push rod 16, which moves the lifting block 17 downward, causing the lifting block 17 to move the cutting machine 18 against the top of the workpiece. At the same time, activate the dust extraction fan 22 and the cutting machine 18. While the cutting machine 18 is cutting the hardware workpiece, the dust extraction fan 22 drives the air at the bottom of the dust extraction frame 20 to flow into the dust extraction frame 20 through the hose 21, so that the dust and waste generated by the cutting machine 18 are sucked from the dust extraction frame 20 into the hose 21. The dust and waste enter the collection box 24 in the waste bin 23 through the hose 21 and the dust extraction fan 22 for collection. As the motor 12 drives the movable threaded rod 13 to rotate, the movable threaded rod 13 drives the slider 14 to move, so that the slider 14 drives the cutting machine 18 to move through the electric push rod 16, thus completing the cutting process of the hardware workpiece.
