[0002] CNC horizontal metal band saw is a device used for sawing different metal materials. It can achieve precise automatic operation, including the design with CNC system, which can be operated by program to improve production efficiency and accuracy. The device is usually composed of motor, gear, guide rail, etc., and can be cut in a variety of ways, such as horizontal, vertical, 45 degree bevel, etc.

[0003] When using a traditional CNC horizontal metal band saw, the material is cut and separated by rotating the metal band saw. However, due to the high-speed rotation and friction between the metal band saw and the material, debris will be generated, which may cause harm to the operator. Therefore, the operator places the cover on the top of the saw. This operation is convenient and quick, but the traditional cover requires the release of multiple sets of bolts for combined fixing. It is very laborious when replacing original parts and repairing the saw.

[0004] Therefore, it is particularly important to improve the protective device of the existing CNC horizontal metal band saw machine, design a new CNC horizontal metal band saw machine protective device to solve the above technical defects, and improve the practicality of the overall CNC horizontal metal band saw machine protective device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Example:

[0023] See also Figure 1-Figure 5 , the utility model provides a technical solution:

[0024] A protective device for a CNC horizontal metal band sawing machine comprises a cover 1, the cover 1 comprises a first shell 2 and a second shell 3, protective plates 4 are symmetrically mounted on the outside of the first shell 2 and the second shell 3, reinforcing rods 5 are mounted between the protective plates 4, and a disassembly assembly 6 is mounted between the first shell 2 and the second shell 3;

[0025] The disassembly assembly 6 is used for quickly connecting the first shell 2 and the second shell 3 .

[0026] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4In this embodiment, the disassembly assembly 6 includes a connecting frame 601, a linkage rod 602, a driven rod 603, a driving rod 604, a first hook 605 and a second hook 606. The connecting frame 601 is installed at the top of the outer side of the first shell 2, the linkage rod 602 and the driven rod 603 are respectively installed inside the connecting frame 601, the driving rod 604 is installed between the linkage rod 602 and the driven rod 603, the first hook 605 is installed at one end of the driven rod 603 away from the driving rod 604, and the second hook 606 is installed at a position corresponding to the first hook 605 inside the second shell 3. When the CNC horizontal metal band saw is in use, the material is cut and separated by the rotation of the metal band saw, but the high-speed rotation friction between the metal band saw and the material will produce fragments. The first shell 2 and the second shell 3 are used to wrap the outside of the metal band saw, and the first shell 2 and the second shell 3 are combined, so that the bottom roller of the first shell 2 is inserted into the placement groove at the bottom of the second shell 3, and the first hook 605 and the second hook 606 are driven to fit each other, and then the linkage rod 602 is turned 90 degrees, so that the driving rod 604 is bent, and then the driven rod 603 is pressed to move the driven rod 603 away from the first shell 2, so that the first hook 605 follows the movement, and the first hook 605 and the second hook 606 are fitted together, and the first shell 2 and the second shell 3 are combined into a whole, so that the debris is blocked.

[0027] Among them, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a receiving groove 607 is provided inside the linkage rod 602 and the driven rod 603. The driving rod 604 is respectively connected to the linkage rod 602 and the driven rod 603 through the receiving groove 607. A handle 608 is installed at the end of the linkage rod 602 away from the driving rod 604. Through the design of the receiving groove 607, when the driving rod 604 rotates, its protruding part will squeeze the receiving groove 607, thereby realizing the outward movement of the driven rod 603.

[0028] Furthermore, please see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a waist groove 609 is opened at the top of the driven rod 603, a limiting rod 610 is installed inside the waist groove 609, and a limiting plate is installed on the top of the limiting rod 610. When the driven rod 603 moves outward, the position and distance of the driven rod 603 are limited by the design of the waist groove 609 and the limiting rod 610, which effectively prevents it from being offset.

[0029] For further information, see Figure 1 , Figure 2 , Figure 3 and Figure 4 In this embodiment, a through groove is opened inside the second shell 3, and the second hook 606 is connected to the second shell 3 through the through groove. A telescopic spring 611 is installed at the end of the second hook 606 away from the first shell 2. The telescopic spring 611 is extended by the mutual fit of the first hook 605 and the second hook 606. At the same time, the telescopic spring 611 will generate a pulling force on the second hook 606, so that the first hook 605 and the second hook 606 can fit more closely.

[0030] For further information, see Figure 2 In this embodiment, a suction fan is installed on the outside of the second shell 3, a dust collecting frame 7 is installed in the middle of the inner side of the second shell 3, and a connecting pipe 8 is installed inside the dust collecting frame 7. When the metal band saw comes into contact with the material, the suction fan is started to generate suction inside the dust collecting frame 7. Through the design of the connecting pipe 8, the contact area between the dust collecting frame 7 and the inside of the cover shell 1 is reduced, thereby further improving the suction force and collecting the debris inside the cover shell 1.

[0031] For further information, see Figure 1 , Figure 2 and Figure 5 In this embodiment, a fixing frame 9 is installed in the middle of the outside of the first shell 2, and multiple groups of folding doors 10 are installed inside the fixing frame 9. Conversion heads 11 are installed at the top and bottom ends between the multiple groups of folding doors 10. A sliding rod 12 is installed on the side of the conversion head 11 away from the folding door 10. By toggling the folding door 10 and the design of the conversion head 11, the folding door 10 is retracted to present a W-shaped structure design. At the same time, the sliding rod 12 slides on the fixing frame 9 to realize the retraction of the folding door 10 to one side of the fixing frame 9. The fixing frame 9 makes the interior of the first shell 2 open, so as to better observe the cutting situation inside the metal band saw.

[0032] In this embodiment, the implementation scenario is specifically as follows: when the CNC horizontal metal band saw is in use, the material is cut and separated by rotating the metal band saw. However, due to the high-speed rotation and friction between the metal band saw and the material, debris will be generated, which may cause harm to the operator. The first shell 2 and the second shell 3 are used to wrap the outside of the metal band saw, and the first shell 2 and the second shell 3 are merged, so that the bottom end roller of the first shell 2 is inserted into the inside of the placement groove at the bottom end of the second shell 3, and at the same time, the first hook 605 and the second hook 606 are driven to fit each other. By holding the handle 608 and pulling it, the linkage rod 602 is rotated 90 degrees, thereby driving the driving rod 604 to bend, and its protruding part squeezes the accommodating groove 607, so that the driven rod 603 moves outward, so that the first hook 605 makes a following movement, and the first hook 605 and The second hooks 606 fit together to extend the telescopic spring 611. At the same time, the telescopic spring 611 will generate a pulling force on the second hook 606, so that the first hook 605 and the second hook 606 fit more closely, and the first shell 2 and the second shell 3 are merged into a whole, so that the debris is blocked, and the suction fan is started to generate suction inside the dust collecting frame 7. Through the design of the connecting pipe 8, the contact area between the dust collecting frame 7 and the inside of the cover shell 1 is reduced, so that the suction is further improved, and the debris inside the cover shell 1 is collected. By turning the folding door 10 and the design of the conversion head 11, the folding door 10 is retracted to present a W-shaped structure design. At the same time, the sliding rod 12 slides on the fixing frame 9 to realize the retraction of the folding door 10 to one side of the fixing frame 9. The fixing frame 9 makes the interior of the first shell 2 open, so as to better observe the cutting situation inside the metal band saw.
