Technical Field

[0001] This utility model relates to the field of CNC metal cutting technology, specifically to a CNC metal band saw. Background Technology

[0002] There are two common types of band saws: horizontal band saws and vertical band saws. By connecting to a CNC system, they can achieve fully automatic CNC cutting. After the raw material is fed in according to the set cutting angle, thickness and trajectory, the saw wheel drives the saw band to cut large steel band saws. However, the horizontal metal CNC band saws on the market still have various shortcomings and cannot meet the needs of production.

[0003] A search revealed Chinese Patent Publication No. CN201920891733.7, which discloses a novel CNC metal band saw. By setting up a fixed baffle frame and a conveyor belt, the material can be transported to the cutting position via the conveyor belt. The fixed baffle frame can effectively protect the material from deviation during material transport, thus ensuring error-free cutting. However, when cutting materials of different sizes, the fixed baffle frame is difficult to guide the materials well. Therefore, it is necessary to design a novel CNC metal band saw with high precision to solve the above-mentioned technical problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A CNC metal band saw includes a mounting base 1, a positioning component 2 on the top of the mounting base 1, a cutting frame 3 rotatably connected to the top of the mounting base 1 and above the positioning component 2 via a connecting shaft, a feeding mechanism 4 on the front of the mounting base 1, and a unloading frame 5 on the back of the mounting base 1.

[0025] In this embodiment, a support frame 101 is fixedly connected to the back of the mounting base 1, and a first driving component 102 is installed at the bottom of the support frame 101. In this embodiment, the first driving component 102 is preferably a hydraulic cylinder, a pneumatic cylinder, etc. The first driving component 102 passes through the support frame 101 and is connected to a connecting column 103 through a hinge seat. The connecting column 103 is fixedly connected to the cutting frame 3.

[0026] As a preferred embodiment of this invention, the mounting base 1 is first placed at a designated position, the feeding mechanism 4 is installed in front of the mounting base 1, and the unloading rack 5 is installed behind the mounting base 1. The feeding mechanism 4 drives the CNC metal to move and transport the CNC metal to the inside of the positioning component 2. The positioning component 2 clamps and fixes the pipe. Then, the CNC metal is cut by the cutting rack 3. After the cutting is completed, the unloading rack 5 unloads the material.

[0027] In this embodiment, please refer to Figure 1 The top of the mounting base 1 is provided with a positioning component 2. The top of the mounting base 1 and above the positioning component 2 are rotatably connected to the cutting frame 3 via a connecting shaft. The positioning component 2 and the cutting frame 3 are used to stably cut CNC metal. The specific structure of the positioning component 2 is as follows:

[0028] The positioning component 2 includes two sets of support blocks 201, a second driving member 202, a pressure plate 203, and a positioning clamp 204. Both sets of support blocks 201 are fixedly connected to the top of the mounting base 1 and located below the cutting frame 3. Both sets of support blocks 201 are connected to the pressure plate 203 through the second driving member 202. In this embodiment, the second driving member 202 is preferably a hydraulic cylinder, a pneumatic cylinder, etc. The positioning clamp 204 is provided below the cutting frame 3 and at the corresponding positions of the two sets of pressure plates 203.

[0029] A cutting cover 301 is installed on the top of the cutting frame 3. A cutting blade 302 is rotatably connected inside the cutting cover 301. A cutting motor 303 is installed on the right side of the cutting frame 3 at the position corresponding to the cutting blade 302. The cutting motor 303 passes through the cutting cover 301 and is connected to the cutting blade 302.

[0030] In a preferred embodiment of this invention, the CNC metal is conveyed to the lower part of the cutting frame 3 by the feeding mechanism 4, and the CNC metal is limited and fixed by the positioning component 2. The second driving component 202 drives the pressure plate 203 to move, and then the pressure plate 203 squeezes the CNC metal onto the support block 201. Then, the positioning clamp 204 limits the upper part of the CNC metal, improving the clamping effect. At this time, the cutting motor 303 drives the cutting blade 302 to rotate inside the cutting cover 301, and the cutting cover 301 protects the cutting blade 302.

[0031] In this embodiment, please refer to Figure 1 The mounting base 1 has a feeding mechanism 4 on its front and a unloading rack 5 on its back. The feeding mechanism 4 and the unloading rack 5 are used for rapid loading and unloading of CNC metal. The specific structure of the feeding mechanism 4 and the unloading rack 5 is as follows:

[0032] The feeding mechanism 4 includes a feeding frame 401, a feeding conveyor belt 402, a third driving component 403, a first limiting plate 404, rollers 405, and anti-slip protrusions 406. The feeding frame 401 is located on the front of the mounting base 1. The feeding conveyor belt 402 is rotatably connected inside the feeding frame 401. The feeding frame 401 is connected to two sets of first limiting plates 404 through four sets of third driving components 403. In this embodiment, the third driving component 403 is preferably a hydraulic cylinder, a pneumatic cylinder, etc. Several rollers 405 are rotatably connected inside the two sets of first limiting plates 404. Several rubber anti-slip protrusions 406 are fixedly connected to the outer side of the feeding conveyor belt 402. A drive motor is installed on the right side of the feeding frame 401 at a position corresponding to the feeding conveyor belt 402.

[0033] The top left and right sides of the unloading rack 5 are fixedly connected with second limiting plates 501. The top of the unloading rack 5 and the inner side of the two sets of second limiting plates 501 are provided with several rolling wheels 502. The top of the unloading rack 5 and the rear of the several rolling wheels 502 are fixedly connected with a fixing plate 503. The fixing plate 503 is connected to a buffer plate 505 through two sets of buffer springs 504.

[0034] In a preferred embodiment of this invention, the CNC metal is fed by the feeding mechanism 4. A drive motor drives the feeding conveyor belt 402 to rotate within the feeding rack 401, thereby moving the CNC metal. A third drive component 403 moves the first limiting plate 404 along the feeding conveyor belt 402. After adjusting the length between the two sets of first limiting plates 404, they limit the CNC metal, preventing it from shifting during transport. The roller 405 reduces the friction between the first limiting plate 404 and the CNC metal, while the anti-slip protrusion 406 improves... The friction between the feeding conveyor belt 402 and the CNC metal is reduced, and the CNC metal is transported to the bottom of the cutting frame 3. The cutting frame 3 then cuts the CNC metal. After the CNC metal is cut, it is transported to the top of the unloading frame 5 and slides down to the position of the buffer plate 505. The rolling wheel 502 reduces the friction between the CNC metal and the unloading frame 5. The impact force generated during unloading is compressed by the buffer plate 505 to squeeze the buffer spring 504, and the buffer spring 504 is compressed to squeeze the fixed plate 503, which plays a buffering role on the CNC metal. During the unloading process of the CNC metal, the second limit plate 501 plays a limiting role on the CNC metal to prevent the CNC metal from sliding off the unloading frame 5.

[0035] In this embodiment, the specific implementation scenario is as follows: In actual use, the mounting base 1 is first placed at the designated position, the feeding mechanism 4 is installed in front of the mounting base 1, and the unloading rack 5 is installed behind the mounting base 1. The feeding mechanism 4 drives the CNC metal to move and transport the CNC metal to the inside of the positioning component 2. The positioning component 2 clamps and fixes the pipe. Then, the CNC metal is cut by the cutting rack 3. After the cutting is completed, the unloading rack 5 unloads the material. Compared with the existing CNC metal band saw with high precision sawing, this utility model can improve the overall practicality of the CNC metal band saw with high precision sawing through design.
