Description

Technical Field

[0001] The utility model relates to the technical field of metal workpiece processing, and more specifically, to a cutting device for metal workpiece processing. Background Art

[0002] Under the current technological background, cutting devices used for metal workpiece processing usually face a series of technical and safety challenges. First of all, the structure of these devices is relatively simple, and they often rely on manual operation to push the workpiece for cutting. This manual pushing method not only increases the labor intensity of the operator, but also has significant safety hazards. During the cutting process, due to the lack of effective mechanical control, the operator may face risks such as workpiece slippage, improper cutting, and even saw blade breakage, all of which may lead to serious personal safety accidents.

[0003] Secondly, the saw blade used in the cutting device will wear out after long-term use. The wear of the saw blade will not only affect the quality and accuracy of the cutting, but may also increase the difficulty and danger of workpiece processing. In order to maintain the cutting effect and ensure safety, the saw blade needs to be replaced regularly. However, in the existing technology, the disassembly and assembly process of the saw blade is relatively complicated, which not only consumes a lot of time and labor, but also requires specific skills and tools. In addition, different types of saw blades may need to be replaced according to different process requirements, which further increases the complexity of the operation.

[0004] In addition, although some cutting devices are designed with sliding components to achieve the movement of the equipment, these components are also prone to wear during long-term use. The wear of the sliding components will not only affect the operating efficiency of the equipment, but may also lead to a decrease in accuracy and even damage to the equipment. Therefore, these components need to be lubricated and maintained regularly to maintain their good working condition. However, in the prior art, this lubrication and maintenance is usually performed manually, which not only increases the maintenance workload, but may also affect the normal operation of the equipment due to uneven or untimely lubrication.

[0033] A knob 17 is provided at one end of the limiting rod 8 , and the knob 17 is fixedly mounted at one end of the limiting rod 8 .

[0034] A clamping plate 18 is disposed on the outside of the flexible board 11 , and a clamping groove 19 is provided at a corresponding position on the inside of the clamping sleeve 10 .

[0035] A first spring 20 is disposed inside the limiting rod 8 , a ball 21 is disposed at one end of the first spring 20 , and a positioning groove 22 is correspondingly provided on one side of the clamping plate 9 , in which the ball 21 can be movably installed.

[0036] A fixing plate 23 is provided on one side of the flexible plate 11 , a sliding block 24 is provided on the outer side of the supporting plate 12 , a sliding groove 25 is provided at a corresponding position on the inner side of the fixing plate 23 , and the sliding block 24 is slidably installed in the sliding groove 25 .

[0037] In this embodiment, when using the device, first turn on the first motor 2, the first motor 2 drives the saw blade 7 connected to the output end to rotate, and then fix the workpiece to be cut on the top of the fixing frame 1 through an external fixing device, and then turn on the second motor 3, the second motor 3 drives the lead screw 4 connected to the output end to rotate on the support seat 5. Since the bottom end of the mounting frame 6 and the lead screw 4 rotate through threads, the mounting frame 6 will follow the rotation of the lead screw 4 and make corresponding movements. At the same time, the slider 16 set at the bottom end of the mounting frame 6 will slide on the slide rail 15 to ensure the stable movement of the cutting machine. When the saw blade 7 needs to be replaced, first turn the knob 17 in the corresponding direction to rotate the limit rod 8. The ball 21 set on the inner side of the limit rod 8 will slide out of the original positioning groove 22 and compress the first spring 20 connected on one side.

Since the sliding block 24 and the sliding groove 25 are mutually limited, and due to the special structural design of the guide groove 14, the support plate 12 slides in the flexible plate 11. When the sliding block 24 moves from one end of the sliding groove 25 to the other end of the sliding groove 25, the support plate 12 is just at the other end of the inner side of the flexible plate 11, and then the first spring 20 is automatically reset and the ball 21 is pushed up. The limit rod 8 is inserted into the corresponding positioning groove 22, thereby realizing self-locking of the limit rod 8. Thereafter, the limit rod 8 is pulled outward, thereby causing the flexible plate 11 to deform in the clamping sleeve 10. Then the clamping plate 18 will be disengaged from the clamping groove 19, so that the two clamping plates 9 no longer clamp the saw blade 7, thereby realizing rapid disassembly of the saw blade 7. Then, a new saw blade 7 is taken out and installed on one side of the clamping sleeve 10. Then, according to the above operation, the two clamping plates 9 clamp the new saw blade 7.

[0038] See also Figure 5 and Figure 6 As an implementation method of a cutting device for metal workpiece processing with a lubrication mechanism: the lubrication mechanism includes a top block 26, an oil storage tank 27, a blocking block 28 and an oil outlet channel 29, the top block 26 is arranged at the top of the slide rail 15, the oil storage tank 27 is arranged on the inner side of the slider 16, the blocking block 28 can be movably installed at the output end of the oil storage tank 27, and the oil outlet channel 29 is opened on the inner side of the blocking block 28.

[0039] A second spring 30 is provided in the oil storage bin 27 , and one end of the second spring 30 is connected to the blocking block 28 .

[0040] More specifically, when the slider 16 slides on the slide rail 15 and the bottom end of the blocking block 28 contacts the top block 26, the blocking block 28 will gradually move to the top and be gradually pushed into the oil storage bin 27. At the same time, the second spring 30 connected to one side of the blocking block 28 will be compressed, and the input end of the oil outlet pipeline will be connected to the inside of the oil storage bin 27. Then, the lubricating oil stored in the oil storage bin 27 will enter from the input end of the oil outlet channel 29, and then flow out through the input end of the oil outlet channel 29 to achieve lubrication of the slide rail 15. When the blocking block 28 is no longer in contact with the top block 26, the second spring 30 will drive the blocking block 28 to reset, so that the blocking block 28 will re-close the oil storage bin 27.

[0041] In summary, when the overall equipment is in use or running: first turn on the first motor 2, the first motor 2 drives the saw blade 7 connected to the output end to rotate, and then the workpiece to be cut is fixed to the top of the fixing frame 1 through an external fixing device, and then turn on the second motor 3, the second motor 3 drives the lead screw 4 connected to the output end to rotate on the support seat 5. Since the bottom end of the mounting frame 6 and the lead screw 4 rotate through threads, the mounting frame 6 will follow the rotation of the lead screw 4 and make corresponding movements. At the same time, the slider 16 set at the bottom end of the mounting frame 6 will slide on the slide rail 15 to ensure the stable movement of the cutting machine. When the saw blade 7 needs to be replaced, first turn the knob 17 in the corresponding direction to rotate the limit rod 8. The ball 21 set on the inner side of the limit rod 8 will slide out of the original positioning groove 22 and compress the first spring 20 connected on one side. At the same time, the top rod 13 set on the inner side of the support plate 12 will move in the guide groove 14, and the outer side of the support plate 12 The sliding block 24 arranged on the side will slide in the sliding groove 25 opened on the inner side of the fixed plate 23. Since the sliding block 24 and the sliding groove 25 form a mutual limit, and due to the special structural design of the guide groove 14, the support plate 12 will slide in the flexible plate 11. When the sliding block 24 moves from one end of the sliding groove 25 to the other end of the sliding groove 25, the support plate 12 is just at the other end of the inner side of the flexible plate 11, and then the first spring 20 will automatically reset and push the ball 21 to the top The limit rod 8 is inserted into the corresponding positioning groove 22, thereby realizing self-locking of the limit rod 8. Thereafter, the limit rod 8 is pulled outward, thereby causing the flexible plate 11 to deform in the clamping sleeve 10. Then the clamping plate 18 will be disengaged from the clamping groove 19, so that the two clamping plates 9 no longer clamp the saw blade 7, thereby realizing rapid disassembly of the saw blade 7. Then, a new saw blade 7 is taken out and installed on one side of the clamping sleeve 10. Then, according to the above operation, the two clamping plates 9 clamp the new saw blade 7.

[0042] When the slider 16 slides on the slide rail 15, after the bottom end of the blocking block 28 contacts the top block 26, the blocking block 28 will gradually move to the top and be gradually pushed into the oil storage bin 27. At the same time, the second spring 30 connected to one side of the blocking block 28 will be compressed, and the input end of the oil outlet pipeline will be connected to the inside of the oil storage bin 27. Then, the lubricating oil stored in the oil storage bin 27 will enter from the input end of the oil outlet channel 29, and then flow out through the input end of the oil outlet channel 29 to achieve lubrication of the slide rail 15. When the blocking block 28 is no longer in contact with the top block 26, the second spring 30 will drive the blocking block 28 to reset, so that the blocking block 28 will re-close the oil storage bin 27.
