[0021] 2. The metal cutting device used for door and window manufacturing has a clamping assembly that is set up. When the first rotating shaft rotates, the first pulley will rotate at the same time. The first pulley rotates the second pulley through the cooperation of the belt, thereby driving the second rotating shaft to rotate. The second rotating shaft drives the second gear to rotate. The rotation of the second gear will drive the second rack to move downward, thereby moving the first fixed block and the second clamping block downward. When the metal moves to the bottom of the cutting body, the second clamping block just clamps the metal, so that the metal is clamped and fixed, which can ensure that the metal remains stable during the cutting process and prevent cutting deviations caused by movement or vibration.

[0022] 3. The metal cutting device used for door and window manufacturing clamps and fixes the metal through the provided cutting mechanism, and then starts the second motor to rotate the worm, which drives the worm wheel to rotate, thereby rotating the screw. Since the rectangular frame is rotated by two limit rods and the rectangular frame is threadedly connected to the surface of the screw, the rotation of the screw will drive the rectangular frame to move downward, thereby moving the cutting body downward to cut the clamped metal.

[0023] 4. The metal cutting device used for door and window manufacturing, through the provided shielding mechanism, when the rectangular frame moves downward, it will drive the two protective covers to move downward. The downward movement of the protective cover will cause the pressure plate to contact the top of the base. When the protective cover continues to move downward, its two first hinged frames move toward each other on the surface of the guide rod, thereby squeezing the spring. The protective cover will be buffered by the spring elastic force, so that the bottom of the protective cover will not contact the top of the base. The two-grid protective cover will protect the staff, so that the staff will not be splashed with high temperature, high pressure, high speed metal chips, sparks and other splashes generated during the cutting process, causing corrosion damage to the skin of the staff. The protective cover can effectively block these splashes and reduce the risk of injury to the operator. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Furthermore, a groove matching the rectangular frame 46 is provided at the bottom of the base 1 near the back, and the surface of the rectangular frame 46 penetrates and is slidably connected in the groove.

[0050] Embodiment 3

[0051] See also Figure 8-9 , and on the basis of the first embodiment, a shielding mechanism 5 is further obtained.

[0052] Furthermore, the shielding mechanism 5 includes a second fixed block 51, which is fixedly connected to the left side of the rectangular frame 46 near the top, a protective cover 52 is fixedly connected to the left side of the second fixed block 51, a fourth fixed frame 53 is fixedly connected to the left bottom of the protective cover 52, a guide rod 54 is fixedly connected to the front and rear of the fourth fixed frame 53, a first hinged frame 55 is symmetrically slidably connected to the surface of the guide rod 54, a hinged rod 56 is hinged in the first hinged frame 55, and a second hinged frame 57 is hinged at the other end of the hinged rod 56, a pressure plate 58 is fixedly connected to the bottom of the second hinged frame 57, a spring 59 is sleeved on the surface of the guide rod 54 between the inner side of the fourth fixed frame 53 and the first hinged frame 55, a slider 512 is fixedly connected to the top of the first hinged frame 55, and a slide groove 511 is provided at the top of the fourth fixed frame 53.

[0054] Furthermore, a groove matching with the first clamping block 319 is opened on the left side of the bottom of the protective cover 52 , and there are two sets of shielding mechanisms 5 , which are symmetrically arranged on the left and right sides of the rectangular frame 46 .

[0055] In actual operation, when the device is used, metal is placed in the two first blocks 319 at the top of the moving plate 318, and then the first motor 314 is started to rotate the first shaft 312. The rotation of the first shaft 312 drives the two first gears 315 to rotate, so that the first rack 3111 moves backward, and the first rack 3111 drives the cross block 317 to move backward in the cross groove 316, and further drives the moving plate 318 and the two first blocks 319 at the top thereof to move backward, thereby driving the metal in the first blocks 319 to move backward, until the metal is moved to the bottom of the cutting body 48, and then the operation of the first motor 314 can be stopped. The process of moving the metal can replace manual transportation of the metal to the bottom of the cutting body 48, without manual intervention, thereby greatly improving the transportation efficiency;

[0056] The rotation of the first shaft 312 will cause the first pulley 323 to rotate at the same time. The first pulley 323 rotates the second pulley 324 through the cooperation of the belt 325, thereby driving the second shaft 322 to rotate. The second shaft 322 drives the second gear 326 to rotate. The rotation of the second gear 326 drives the second rack 328 to move downward, thereby causing the first fixing block 329 and the second clamping block 3211 to move downward. When the metal moves to the bottom of the cutting body 48, the second clamping block 3211 just clamps the metal, thereby clamping and fixing the metal, which can ensure that the metal remains stable during the cutting process and prevent cutting deviations caused by movement or vibration.

[0057] After the metal is clamped and fixed, the second motor 42 is started to rotate the worm 43, and the worm 43 drives the worm wheel 45 to rotate, so that the screw 44 rotates. Since the rectangular frame 46 is rotated by the two limit rods 47, and the rectangular frame 46 is threadedly connected to the surface of the screw 44, the rotation of the screw 44 drives the rectangular frame 46 to move downward, so that the cutting body 48 moves downward to cut the clamped metal;

[0058] When the rectangular frame 46 moves downward, it will drive the two protective covers 52 to move downward. The downward movement of the protective covers 52 will cause the pressure plate 58 to contact the top of the base 1. When the protective cover 52 continues to move downward, its two first hinge frames 55 move toward each other on the surface of the guide rod 54, thereby squeezing the spring 59. The protective cover 52 will be buffered by the elastic force of the spring 59, so that the bottom of the protective cover 52 will not contact the top of the base 1. The two-grid protective covers 52 will protect the staff, so that the staff will not be splashed with high temperature, high pressure, high speed metal chips, sparks and other splashes generated during the cutting process, causing corrosion damage to the skin of the staff. The protective cover 52 can effectively block these splashes and reduce the risk of injury to the operator.
