Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0027] Please see Figures 1-3 This utility model provides a technical solution: a protective device for a CNC horizontal metal band saw, including a CNC horizontal metal band saw body 1, with placement slots opened on the outer side of the CNC horizontal metal band saw body 1, a protective mechanism 2 provided on the outer side of the CNC horizontal metal band saw body 1, and a buffer mechanism 3 provided on the bottom surface of the CNC horizontal metal band saw body 1.

[0028] The protective mechanism 2 includes a drive unit 21 and a protective unit 22;

[0029] The protective part 22 is located on the left side of the drive part 21;

[0030] The buffer mechanism 3 includes a sliding part 31 and a buffer part 32;

[0031] The buffer part 32 is located on the inner side of the sliding part 31.

[0032] The drive unit 21 includes a fixed base 211, with two fixed bases 211 arranged at the front and rear. A motor 212 is provided on the top surface of each fixed base 211. The motor 212 is fixedly connected to the fixed base 211. A U-shaped plate 213 is provided on the front side of each motor 212. The U-shaped plate 213 is fixedly connected to the right side of the CNC horizontal metal band saw body 1. The rear side of the U-shaped plate 213 is fixedly connected to the front side of the fixed base 211. The motor 212 extends through to the inner side of the U-shaped plate 213. The output end face of the motor 212 is rotatably connected to the inner side of the U-shaped plate 213 through a bearing seat.

[0033] Worm gears 214 are provided on the inner side of the U-shaped plate 213. The worm gears 214 are fixedly connected to the output end face of the motor 212. The front end face of the worm gears 214 is rotatably connected to the inner side of the U-shaped plate 213 through the bearing seat 2. A fixing plate 215 is provided above the worm gears 214. The fixing plate 215 is fixedly connected to the top surface of the U-shaped plate 213.

[0034] The protective part 22 includes a gear column 221. There are two gear columns 221 arranged at the front and rear. The right end face of the gear column 221 is rotatably connected to the left side face of the fixed plate 215 through the bearing seat 3. The left end face of the gear column 221 is provided with a worm gear 222. The worm gear 222 is fixedly connected to the gear column 221 and meshes with the worm 214.

[0035] Each worm gear 222 has a rotating rod 223 on its left end face. The rotating rod 223 is fixedly connected to the worm gear 222. The rotating rod 223 extends through to the inner side of the placement groove. The surface of the rotating rod 223 is rotatably connected to the inner wall of the CNC horizontal metal band saw body 1 through bearing seat four. The left end face of the rotating rod 223 is rotatably connected to the inner side of the placement groove through bearing seat five.

[0036] Rotating plates 224 are fitted on the surface of rotating rod 223. Rotating plates 224 are fixedly connected to rotating rod 223. Protective plates 225 are provided on the top surface of rotating plates 224. Protective plates 225 are fixedly connected to rotating plates 224.

[0037] Furthermore, in this embodiment, through the protective mechanism 2, the motor 212 in the drive unit 21 starts when the CNC horizontal metal band saw body 1 begins processing. The rotational power of the motor 212 is transmitted to the worm gear 214, causing the worm gear 214 to start rotating. The rotation of the worm gear 214 drives the rotation of the worm wheel 222, which in turn drives the rotation of the rotating rod 223 connected to it. The rotation of the rotating rod 223 causes the rotating plate 224 and the protective plate 225 fixed to it to rotate together. As the process proceeds, the protective plate 225 gradually rotates from its initial position to a vertical position, effectively blocking the flying of chips that may be generated during the band sawing process. When the CNC horizontal metal band saw body 1 completes the processing task, the motor 212 will rotate in the opposite direction. Through the same transmission mechanism of worm 214 and worm wheel 222, the rotating rod 223, rotating plate 224 and protective plate 225 will rotate in the opposite direction, gradually rotating back to their original position from the vertical position. At this time, the protective plate 225 is matched with the placement groove, maintaining the original state of the protective mechanism 2.

[0038] Furthermore, in this embodiment, the protective mechanism 2 utilizes the motor 212 in the drive unit 21. The motor 212 drives the worm gear 214, which in turn drives the worm wheel 222. The worm wheel 222 then drives the rotating rod 223, which in turn drives the rotating plate 224 and the protective plate 225, thus rotating them into a vertical position for protection. When the CNC horizontal metal band saw body 1 is no longer processing, it rotates in the opposite direction, allowing the protective plate 225 to fit into the placement groove and maintain its original state. This facilitates protection for the operator during processing and prevents debris from flying. Example

[0039] Please see Figure 1 Figure 2 , Figure 4 Furthermore, based on Embodiment 1, the sliding part 31 includes a placement sleeve 311, with two sets of placement sleeves 311 arranged on the left and right sides. Each placement sleeve 311 has a through groove on its inner side. The top surface of the placement sleeve 311 is fixedly connected to the bottom surface of the CNC horizontal metal band saw body 1. Each through groove has a sliding rod 312, which is fixedly connected to the through groove. Each sliding rod 312 has a moving plate 313 on its inner side, which is sleeved on the surface of the sliding rod 312 and slidably connected to the sliding rod 312.

[0040] The buffer section 32 includes a damper 321. The top end of the damper 321 is fixedly connected to the inner side of the placement sleeve 311, and the bottom end of the damper 321 is fixedly connected to the top surface of the moving plate 313. A support rod 322 is provided below each damper 321. The support rod 322 is fixedly connected to the bottom surface of the moving plate 313. The support rod 322 extends through to the bottom of the placement sleeve 311 and is slidably connected to the inner wall of the placement sleeve 311. A shock-absorbing pad 323 is fixedly provided on the bottom surface of the support rod 322.

[0041] Furthermore, in this embodiment, through the buffer mechanism 3, the placement sleeve 311 in the sliding part 31 is used. When the CNC horizontal metal band saw body 1 is processing, the placement sleeve 311 will first sense the vibration generated by the sawing operation. As a medium for vibration transmission, the placement sleeve 311 transmits the vibration to the moving plate 313 connected to it. After receiving the vibration, the moving plate 313 will slide along its surface under the constraint of the sliding rod 312. At the same time, as the moving plate 313 slides, the placement sleeve 311 will also slide relative to the receiving rod 322. In this sliding process, the damper 321 plays a key role. The damper 321 dampens the sliding motion through its internal damping medium, further consuming the vibration energy.

[0042] Furthermore, in this embodiment, through the buffer mechanism 3, the placement sleeve 311 in the sliding part 31 is used. When the CNC horizontal metal band saw body 1 is processing, the vibration is applied to the placement sleeve 311, which in turn acts on the moving plate 313, causing the moving plate 313 to slide on the surface of the slide rod 312. This allows the placement sleeve 311 to slide with the receiving rod 322, thereby using the damper 321 to reduce shock and buffer, improving the safety and efficiency of the band saw operation, while protecting the workpiece and the band saw itself from damage.

[0043] In use, the motor 212 in the drive unit 21 is activated by the protective mechanism 2. When the CNC horizontal metal band saw body 1 starts processing, the motor 212 is activated and the rotational power of the motor 212 is transmitted to the worm 214, causing the worm 214 to start rotating. The rotation of the worm 214 drives the rotation of the worm wheel 222, and the rotation of the worm wheel 222 further drives the rotation of the rotating rod 223 connected to it. The rotation of the rotating rod 223 causes the rotating plate 224 and the protective plate 225, which are fixed to it, to rotate together. As the rotation proceeds, the protective plate 225 gradually rotates from its initial position to a vertical position, effectively blocking the flying debris that may be generated during the band sawing process. When the CNC horizontal metal band saw body 1 completes the processing task, the motor 212 will rotate in the opposite direction. Through the same transmission mechanism of the worm 214 and worm wheel 222, the rotating rod 223, the rotating plate 224, and the protective plate 225 will rotate in the opposite direction, gradually rotating from the vertical position back to their original position. At this time, the protective plate 225 is adapted to the placement groove, maintaining the original state of the protective mechanism 2. Through the buffer mechanism 3, the sliding part 31... When the CNC horizontal metal band saw body 1 is processing, the placement sleeve 311 will first sense the vibration generated by the sawing operation. As a medium for vibration transmission, the placement sleeve 311 transmits these vibrations to the moving plate 313 connected to it. After receiving the vibration, the moving plate 313 will slide along its surface under the constraint of the slide rod 312. At the same time, as the moving plate 313 slides, the placement sleeve 311 will also slide relative to the receiving rod 322. In this sliding process, the damper 321 plays a key role. The damper 321 dampens the sliding motion through its internal damping medium, further consuming the vibration energy.

[0044] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
