Description

Technical Field

[0001] The invention relates to the technical field of numerically controlled machine tools, in particular to an iron chip recovery device in a numerically controlled machine tool with an iron chip pretreatment function. Background Art

[0002] CNC machine tools (Computer Numerical Control Machine Tools, referred to as CNC machine tools) are automated machine tools controlled by computers. They receive input program instructions through the numerical control system. CNC machine tools are modern machine tools that integrate computer technology, precision machinery, automatic control, and detection and sensing technologies. The computer in the numerical control device processes the information recorded by the input device in digital and character encoding, and then issues instructions to the machine tool spindle and feed actuators through the servo system and programmable controller. The machine tool body completes the processing of the workpiece according to these instructions.

[0003] As one of the core equipment in modern manufacturing, CNC machine tools have excellent performance characteristics - high precision, high efficiency, high reliability and high flexibility, which not only profoundly affect the operation mode of traditional manufacturing, but also play an indispensable role in promoting the transformation of manufacturing to intelligence and refinement. Under the current wave of Industry 4.0, the potential and value of CNC machine tools are further explored and released. With the rapid development of science and technology, CNC machine tools are gradually moving towards a new era of intelligence. By integrating advanced sensor technology, artificial intelligence algorithms and big data analysis, CNC machine tools can realize functions such as self-diagnosis, predictive maintenance and intelligent path planning, thereby significantly improving production efficiency and processing quality, and reducing human errors and downtime. At the same time, intelligent CNC machine tools can also be flexibly adjusted according to production needs, realize rapid production change and customized production, and meet the increasingly diversified product needs of the market.

[0004] When CNC machine tools are working, they will generate a lot of iron chips, which may get stuck in the transmission parts of the machine tools, causing the parts to wear more during operation. Long-term accumulation may cause machine tool failures, affecting production efficiency and machine tool life. In addition, the accumulation of iron chips increases the difficulty of cleaning and maintenance of machine tools, requiring regular shutdown for cleaning, which reduces the utilization rate of machine tools.

[0005] Moreover, the iron chips are sharp and easy to splash, which can easily pierce the skin or injure the eyes, causing trauma or infection risks to the operator. The accumulation of iron chips will make the working environment dirty and increase the labor intensity and psychological burden of the operator.

[0006] Therefore, we propose an iron chip recovery device in a CNC machine tool with an iron chip pretreatment function to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide an iron chip recycling device in a numerically controlled machine tool with an iron chip pretreatment function, so as to solve the problems put forward in the above-mentioned background technology.

[0008] To achieve the above object, the present invention provides the following technical solution: An iron chip recycling device in a numerically controlled machine tool with an iron chip pretreatment function, including a numerically controlled machine tool body and a processing seat arranged on one side of the numerically controlled machine tool body. A recycling groove is opened on the surface of the processing seat, and a plurality of crushing rollers are arranged in the inner cavity of the recycling groove. A plurality of exhaust fans are fixedly connected to the top of the recycling groove. A pushing groove is opened on one side of the inner wall of the recycling groove, and a processing groove is opened on the other side of the inner wall of the recycling groove, and a part of the processing groove penetrates through the bottom of the processing seat;

[0009] A plurality of telescopic cylinders are fixedly connected to the inner wall of the pushing groove, and the other ends of the plurality of telescopic cylinders are fixedly connected to a pushing plate;

[0010] A hydraulic rod is fixedly connected to the inner cavity of the processing groove, and the other ends of the hydraulic rods are fixedly connected to a compression plate;

[0011] The surfaces of the exhaust fans are fixedly connected with guiding pipes, and the other ends of the guiding pipes are inserted into the numerically controlled machine tool body and penetrate through the recycling groove.

[0012] In a further embodiment, a discharge valve plate is arranged in the inner cavity of the processing groove, and the discharge valve plate covers the part of the processing groove that penetrates through the bottom of the processing seat.

[0013] In a further embodiment, a plurality of crushing rollers are distributed at equal intervals in the recycling groove, and the crushing rollers are rotationally connected in the recycling groove through a conductive slip ring.

[0014] In a further embodiment, the pushing plate and the compression plate are made of tungsten alloy.

[0015] In a further embodiment, the compression plate is adapted to the processing groove, and the compression plate can be displaced in the inner cavity of the processing groove.

[0016] In a further embodiment, the pushing plate is adapted to the pushing groove, and the pushing plate can be displaced in the inner cavity of the pushing groove.

[0017] In a further embodiment, a plurality of filter net plates corresponding to the guiding pipes are fixedly connected to the inner wall of the recycling groove, and the filter net plates cover the openings of the guiding pipes.

[0018] In a further embodiment, the shape of the recycling groove is "凵", and the notch faces the numerically controlled machine tool body.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. Start the exhaust fan fixedly connected to the top of the CNC machine tool body. The exhaust fan conducts the air extraction work. Under the guidance of the guiding pipe, the suction generated sucks the iron filings accumulated on the surface of the CNC machine tool body into the recovery groove opened on the surface of the processing seat. The shape of the recovery groove is "凵", and the notch faces the CNC machine tool body, ensuring that the iron filings can smoothly fall into the recovery groove, avoiding the residue of iron filings on the surface of the CNC machine tool body or falling to the outside, and preventing the problem that the sharp iron filings are prone to splashing, posing a safety threat to the operator, increasing the labor intensity and mental burden;

[0021] 2. The rotation of the crushing roller uniformly and thoroughly crushes the sucked iron filings. In this process, under the action of a strong crushing force, the iron filings are gradually refined into smaller particles or flakes. This crushing treatment not only reduces the volume of the iron filings but also makes their shape more regular, facilitating subsequent storage, transportation, and reuse. After the crushing treatment, due to the action of its own gravity, the iron filings begin to slowly fall to the bottom of the inner cavity of the recovery groove. The entire iron filing recovery process realizes the automation and high efficiency from suction, crushing to collection, not only greatly improving the efficiency and quality of iron filing recovery but also effectively reducing the complexity of manual operation and potential safety hazards;

[0022] 3. With the continuous pushing of the pushing plate, the iron filing fragments will be sent into the processing groove one by one. The processing groove, as the core area for iron filing collection and preliminary processing, has a large enough internal space to accommodate a large amount of iron filings. When the number of iron filings in the processing groove reaches the preset threshold, start the hydraulic rod in the inner cavity of the processing groove. The hydraulic rod pushes the compression plate to make a stable displacement in the inner cavity of the processing groove. The compression plate is made of a high-strength material, tungsten alloy, to ensure that it can uniformly and effectively compact the iron filing fragments into blocks during the extrusion process. This step not only significantly reduces the volume of the iron filings but also improves their overall density and stability, bringing great convenience to subsequent storage and transportation.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-4 , the present invention provides a technical solution: a chip recycling device in a numerically controlled machine tool with a chip pretreatment function, including a numerically controlled machine tool body 1 and a processing seat 2 arranged on one side of the numerically controlled machine tool body 1. When the numerically controlled machine tool body 1 is working for production and processing, the generated chips accumulate on the surface of the numerically controlled machine tool body 1, and then multiple suction fans 4 are started. Their strong suction force is transmitted to the surface of the numerically controlled machine tool body 1 through the guiding pipe 11. The multiple suction fans 4 and the guiding pipe 11 ensure the uniform distribution of the suction force, and also enable the chips to be quickly and accurately sucked into the recycling tank 12. The recycling tank 12 is in a "U" shape, and its notch directly faces the numerically controlled machine tool body 1. Such a layout greatly improves the chip collection efficiency. Under the action of the suction force, the chips can fall into the recycling tank 12 without any hindrance, thus avoiding the residue of the chips on the machine tool surface or scattering into the surrounding environment. The filter screen plate 14 is located at the entrance of the guiding pipe 11, which can effectively intercept the sucked chips and prevent them from entering the inside of the guiding pipe 11, thereby blocking the pipeline or damaging the suction fan 4, extending the service life of the system and reducing the maintenance cost.

[0030] After the chips are successfully sucked into the recycling tank 12, the crushing roller 3 in the inner cavity of the recycling tank 12 is quickly started. The surface of the crushing roller 3 is covered with a special wear-resistant material, ensuring that when rotating at high speed and colliding with the chips, it can not only effectively crush the chips but also maintain its own long-term durability. As the crushing roller 3 rotates, the sucked chips are uniformly and thoroughly crushed. During this process, under the action of the strong crushing force, the chips are gradually refined into smaller particles or flakes. This crushing treatment not only reduces the volume of the chips but also makes their shapes more regular, facilitating subsequent storage, transportation, and reuse. After the crushing treatment, due to the action of its own gravity, the chips begin to slowly fall to the bottom of the inner cavity of the recycling tank 12. The entire chip recycling process realizes automation and high efficiency from suction, crushing to collection, which not only greatly improves the efficiency and quality of chip recycling but also effectively reduces the cumbersome manual operation and potential safety hazards;

[0031] When the iron filings are crushed successfully, the iron filings will naturally fall into the recovery tank 12 below. At this time, the space inside the recovery tank 12 will be gradually filled with iron filings. In order to further optimize the subsequent processing flow, the system will promptly start the telescopic cylinder 7 preset in the push tank 5, and the telescopic cylinder 7 will jointly push the push plate 8 to move in the inner cavity of the push tank 5.

[0032] After receiving the thrust from the telescopic cylinder 7, the push plate 8 will start to move along the preset trajectory. The bottom of the push plate 8 can fit closely to the bottom of the recovery tank 12, so as to effectively push the iron filings accumulated at the bottom during the movement. The iron filings can be smoothly exported from the recovery tank 12, and it can also ensure that the iron filings maintain a certain degree of compactness during the pushing process, laying the foundation for the subsequent compaction treatment. With the continuous pushing of the push plate 8, the iron filings will be sent into the processing tank 6 one by one. The processing tank 6 is the core area for collecting and preliminarily treating the iron filings, and its internal space is large enough to accommodate a large amount of iron filings. When the number of iron filings in the processing tank 6 reaches the preset threshold, the hydraulic rod 9 in the inner cavity of the processing tank 6 is started, and the hydraulic rod 9 pushes the compression plate 10 to stably displace in the inner cavity of the processing tank 6. The compression plate 10 is made of high-strength tungsten alloy to ensure that the iron filings can be evenly and effectively compacted into blocks during the extrusion process. This step not only significantly reduces the volume of the iron filings, but also improves its overall density and stability, which brings great convenience to subsequent storage and transportation.

[0033] When the iron scraps are successfully compacted into blocks, the discharge valve plate 13 is activated. The discharge valve plate 13 covers the portion of the processing tank 6 that passes through the bottom of the processing seat 2. The opening and closing of the discharge valve plate 13 is controlled by a precise mechanical device. After receiving the command, the discharge valve plate 13 will open quickly, allowing the iron scraps that have been compacted into blocks to be smoothly discharged from the processing tank 6. This process not only improves the overall storage and processing efficiency of the scrap iron, but also ensures the smoothness and efficiency of the entire processing process.

[0034] Working principle: When the numerical control machine tool body 1 is in production and processing, the iron filings generated accumulate on the surface of the numerical control machine tool body 1. Then, multiple groups of exhaust fans 4 are immediately started, and their powerful suction force is transmitted to the surface of the numerical control machine tool body 1 through the guiding pipe 11. The multiple groups of exhaust fans 4 and the guiding pipe 11 ensure the uniform distribution of the suction force and enable the iron filings to be quickly and accurately sucked into the recovery tank 12. The recovery tank 12 is in a "U" shape, and its notch directly faces the numerical control machine tool body 1. Such a layout greatly improves the collection efficiency of the iron filings. Under the action of the suction force, the iron filings can fall into the recovery tank 12 unobstructed, thus avoiding the residue of the iron filings on the machine tool surface or their scattering into the surrounding environment. The filter screen plate 14 is located at the entrance of the guiding pipe 11 and can effectively intercept the sucked iron filings to prevent them from entering the inside of the guiding pipe 11, thereby blocking the pipeline or damaging the exhaust fan 4, extending the service life of the system, and reducing the maintenance cost. After the iron filings are successfully sucked into the recovery tank 12, the crushing rollers 3 in the inner cavity of the recovery tank 12 are immediately started. The surface of the crushing rollers 3 is covered with special wear-resistant materials to ensure that when rotating at high speed and colliding with the iron filings, they can not only effectively crush the iron filings but also maintain their own long-term durability. As the crushing rollers 3 rotate, the sucked iron filings are evenly and thoroughly crushed. During this process, under the action of the powerful crushing force, the iron filings are gradually refined into smaller particles or flakes. This crushing treatment not only reduces the volume of the iron filings but also makes their shape more regular, facilitating subsequent storage, transportation, and reuse. After the crushing treatment of the iron filings, due to the action of their own gravity, they begin to slowly fall to the bottom of the inner cavity of the recovery tank 12. The entire iron filing recovery process realizes the automation and high efficiency from suction, crushing to collection, which not only greatly improves the efficiency and quality of iron filing recovery but also effectively reduces the cumbersome manual operation and potential safety hazards. When the iron filing crushing process is successfully completed, the generated iron filings will naturally fall into the lower recovery tank 12. At this time, the internal space of the recovery tank 12 will be gradually filled with iron filings. To further optimize the subsequent processing flow, the system will promptly start the telescopic cylinders 7 preset in the pushing tank 5. The telescopic cylinders 7 jointly push the pushing plate 8 to move in the inner cavity of the pushing tank 5. After receiving the thrust from the telescopic cylinders 7, the pushing plate 8 will start to move along the preset trajectory. The bottom of the pushing plate 8 can closely fit the bottom of the recovery tank 12, so as to effectively push the iron filing fragments accumulated at the bottom during the movement. The iron filings are smoothly exported from the recovery tank 12, and it can also ensure that the iron filings maintain a certain density during the pushing process, laying a foundation for subsequent compaction treatment. With the continuous pushing of the pushing plate 8, the iron filing fragments will be sent into the processing tank 6 one by one. The processing tank 6, as the core area for iron filing collection and preliminary processing, has a large enough internal space to accommodate a large amount of iron filings. When the number of iron filings in the processing tank 6 reaches the preset threshold, the hydraulic rod 9 in the inner cavity of the processing tank 6 is started. The hydraulic rod 9 pushes the compression plate 10 to move stably in the inner cavity of the processing tank 6.The compression plate 10 is made of high-strength tungsten alloy to ensure that the iron filings can be compacted into blocks evenly and effectively during the extrusion process. This step not only significantly reduces the volume of the iron filings, but also improves its overall density and stability, which greatly facilitates subsequent storage and transportation. When the iron filings are successfully compacted into blocks, the discharge valve plate 13 is started. The discharge valve plate 13 covers the part of the processing tank 6 that passes through the bottom of the processing seat 2, and the opening and closing actions of the discharge valve plate 13 are controlled by a precise mechanical device. After receiving the instruction, the discharge valve plate 13 will open quickly, allowing the iron filings that have been compacted into blocks to be discharged smoothly from the processing tank 6. This process not only improves the overall storage and processing efficiency of waste iron filings, but also ensures the smoothness and efficiency of the entire processing process, and solves the problem that a large amount of iron filings will be generated when the machine tool is running, which is easy to jam the transmission parts, aggravate wear, and cause long-term or failures, affecting efficiency and life. The accumulation of iron filings also increases the difficulty of cleaning, requiring regular shutdown and cleaning, and reducing the utilization rate. The need for regular shutdown and cleaning is reduced, thereby improving the overall utilization rate of the machine tool.
