Description

Technical Field

[0001] The invention relates to the technical field of numerical control electric machining, and in particular to a protective structure and a graphite machining device having the same. Background Art

[0002] In the field of mold manufacturing and precision machining, CNC EDM machine tools play an indispensable role. With the continuous advancement of materials science, graphite has become the preferred material for manufacturing electrodes due to its excellent physical and chemical properties, such as good electrical conductivity, stable high-temperature performance, low thermal expansion coefficient and easy cutting. This not only improves processing efficiency, but also reduces costs, resulting in a surge in demand for graphite processing machine tools, making it a popular product on the market.

[0003] However, the processing of graphite is accompanied by a series of challenges. Graphite is a brittle material that is prone to cracks and breaks during the cutting process, which not only affects the processing accuracy but also increases the frequency of machine tool maintenance. More importantly, a large amount of dust is generated during the graphite processing process. These fine graphite particles not only cause serious pollution to the environment, but may also cause significant harm to the health of operators, especially the upper respiratory tract. In addition, graphite dust is conductive. Once it enters the electrical components of the machine tool, it may cause a short circuit, resulting in equipment failure or damage, affecting production safety.

[0004] At present, the main methods for dust protection of graphite processing machine tools are water curtain dust prevention, vacuum dust collection and sheet metal with sealing rings. Although water curtain dust prevention can intercept dust to a certain extent, its filtering technology is relatively backward and the filtering accuracy is limited, making it difficult to continuously and effectively keep the inside of the machine tool clean; although the vacuum dust collection system can capture most of the dust, it is difficult to completely prevent the penetration of very small amounts of dust, especially when the workbench moves and creates gaps; the sheet metal with sealing ring method requires extremely high processing accuracy of the sheet metal, is costly, and has a complex structure and is inconvenient to maintain.

[0040] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] In the field of mold manufacturing and precision machining, CNC EDM machine tools play an indispensable role. With the continuous advancement of materials science, graphite has become the preferred material for manufacturing electrodes due to its excellent physical and chemical properties, such as good electrical conductivity, stable high-temperature performance, low thermal expansion coefficient and easy cutting. This not only improves processing efficiency, but also reduces costs, resulting in a surge in demand for graphite processing machine tools, making it a popular product on the market.

[0042] However, the processing of graphite is accompanied by a series of challenges. Graphite is a brittle material that is prone to cracks and breaks during the cutting process, which not only affects the processing accuracy but also increases the frequency of machine tool maintenance. More importantly, a large amount of dust is generated during the graphite processing process. These fine graphite particles not only cause serious pollution to the environment, but may also cause significant harm to the health of operators, especially the upper respiratory tract. In addition, graphite dust is conductive. Once it enters the electrical components of the machine tool, it may cause a short circuit, resulting in equipment failure or damage, affecting production safety.

[0043] At present, the main methods for dust protection of graphite processing machine tools are water curtain dust prevention, vacuum dust collection and sheet metal with sealing rings. Although water curtain dust prevention can intercept dust to a certain extent, its filtering technology is relatively backward and the filtering accuracy is limited, making it difficult to continuously and effectively keep the inside of the machine tool clean; although the vacuum dust collection system can capture most of the dust, it is difficult to completely prevent the penetration of very small amounts of dust, especially when the workbench moves and creates gaps; the sheet metal with sealing ring method requires extremely high processing accuracy of the sheet metal, is costly, and has a complex structure and is inconvenient to maintain.

[0044] The main purpose of the present invention is to provide a protective structure and a graphite processing device having the same, so as to solve the problem in the prior art that dust enters into the interior of the machine tool during the graphite processing process.

[0045] The present application first provides a protection structure, including a protection unit 4, the protection unit 4 includes:

[0046] A protective cover 100, the protective cover 100 is used to cover the outside of the component to be protected;

[0047] A protective plate 300, at least part of which is disposed in the protective cover 100, a protective groove 200 is provided at one end of the protective plate 300 away from the protective cover 100, at least part of which is in the protective groove 200, and the bottom of the protective groove 200 is used to connect with the base to be installed to prevent dust from entering the interior of the protective cover 100 from the gap between the component to be protected and the base to be installed.

[0048] Specifically, Figures 1 to 3 As shown, the protection structure provided by the present application includes a plurality of protection units 4, each protection unit 4 includes a protection cover 100 arranged outside the component to be protected, and also includes a protection plate 300 at least partially arranged inside the protection cover 100, and a protection groove 200 is provided at one end of the protection plate 300 away from the protection cover 100, at least part of the protection cover 100 is located in the protection groove 200, and the bottom of the protection groove 200 is used to connect with the base to be installed, so as to prevent dust from entering the interior of the protection cover 100 through the gap between the component to be protected and the base to be installed.

[0049] It also includes an air delivery unit and an oil delivery unit for delivering compressed gas and oil into the protective groove 200 respectively, so as to achieve oil sealing and air sealing in these two ways.

[0050] The coordinated design of the protective groove 200 and the protective cover 100 forms a unique labyrinth sealing structure, which greatly limits the path of dust entering the interior of the protective cover 100 from the gap between the component to be protected and the base to be installed. Even if tiny gaps are generated during the movement of the workbench or the operation of the machine tool, it can effectively block the intrusion of graphite dust and protect the internal core components from contamination.

[0051] The bottom of the protective groove 200 is firmly connected to the foundation to be installed, which not only improves the overall stability of the protective structure, reduces the sealing failure caused by vibration or movement, and avoids the dust leakage problem caused by excessive side gaps.

[0052] By implementing oil seal and air seal in the protection groove 200, double protection of oil seal and air seal is achieved. The oil seal can effectively block large dust particles, while the air seal can further prevent the penetration of small particles, ensuring the cleanliness of the internal environment of the workbench and improving the long-term operation stability and processing accuracy of the machine tool.

[0053] The design of the protection groove 200 simplifies the matching structure between the protection cover 100 and the protection plate 300, reduces the stringent requirements for sheet metal processing accuracy, and makes the overall structure simpler and easier to maintain. The maintenance work of the oil seal and the air seal is relatively independent, which is easy for local maintenance and adjustment, reducing the maintenance cycle and cost and improving production efficiency.

[0054] It effectively prevents graphite dust from entering the workbench, reduces the wear and corrosion of precision parts such as the screw pair and the guide pair, thereby extending the service life of the graphite processing machine tools, reducing equipment downtime caused by component damage, and providing a guarantee for continuous and efficient production.

[0055] Further, the protective cover 100 includes: a top plate 101;

[0056] At least two side panels 102, wherein the at least two side panels 102 are respectively disposed on both sides of the top panel 101;

[0057] At least two bottom plates 103, wherein the at least two bottom plates 103 are respectively disposed on the at least two side plates 102;

[0058] The horizontal planes where at least two bottom plates 103 are located are parallel to the horizontal plane where the top plate 101 is located.

[0059] Further, the protection groove 200 is arranged in one-to-one correspondence with at least two bottom plates 103;

[0060] The width of the protection groove 200 is greater than the width of the corresponding bottom plate 103 along the first direction, and the depth of the protection groove 200 is greater than the distance between at least two bottom plates 103 and the bottom of the protection groove 200 .

[0061] By providing the protective grooves 200 in one-to-one correspondence with at least two bottom plates 103, and the groove width of the protective grooves 200 is greater than the width of the bottom plate 103 along the first direction, and the groove depth is greater than the distance between the bottom plate 103 and the groove bottom, a tighter sealing structure is formed. This design ensures that the bottom plate 103 of the protective cover 100 can slide smoothly in the protective grooves 200 when moving, while minimizing the possibility of dust entering through the gaps, thereby improving the overall dustproof effect.

[0062] The protective cover 100 is composed of a top plate 101, a side plate 102 and a bottom plate 103, wherein the top plate 101 is parallel to the horizontal plane where at least two bottom plates 103 are located, which not only ensures the structural stability of the protective cover 100, but also improves its adaptability to parts to be protected of different shapes and sizes. The size matching design of the protective groove 200 and the bottom plate 103 enables the protective structure to be flexibly applied to various processing machine tools, thereby enhancing versatility and compatibility.

[0063] The matching structural design between the protective cover 100 and the protective groove 200 makes maintenance more convenient. The protective groove 200 can be cleaned or adjusted without completely disassembling the protective cover 100, which reduces maintenance costs and time, and reduces the impact on production efficiency.

[0064] The combined design of the protective cover 100 and the protective plate 300 not only provides effective protection, but also optimizes the appearance of the machine tool, making it neater and more beautiful. More importantly, it increases the working safety of the operator and avoids safety hazards caused by exposed parts or dust accumulation.

[0065] By effectively preventing the intrusion of graphite dust and other particles, the wear of key components such as screw pairs and guide rail pairs is reduced, thereby extending the service life of the processing machine. Especially for graphite processing machine tools, the design of this protective structure can significantly reduce the maintenance frequency, reduce unplanned downtime caused by component damage, and improve the operating efficiency and economic benefits of the equipment.

[0066] Further, the protection groove 200 includes: a first matching portion 201, the first matching portion 201 extends along a first direction;

[0067] A second matching portion 202, the second matching portion 202 extends along a second direction;

[0068] The first end of the second matching portion 202 is connected to the first end of the first matching portion 201 , and the first direction is perpendicular to the second direction.

[0069] The protection groove 200 forms an L-shaped structure through the design of the first matching portion 201 and the second matching portion 202, wherein the first matching portion 201 extends along a first direction, and the second matching portion 202 extends along a second direction perpendicular to the first direction. This structure can closely fit the bottom plate 103 of the protection cover 100, realize multi-directional sealing, effectively prevent graphite dust from entering the interior of the workbench from different angles, and greatly enhance the accuracy and comprehensiveness of protection.

[0070] The L-shaped protection groove 200 not only increases the contact area with the bottom plate 103 of the protection cover 100, but also improves the strength and stability of the overall structure by changing the force transmission path. Even under extreme conditions or high-frequency movements, a good sealing effect can be maintained to avoid sealing failure caused by insufficient structural strength.

[0071] The smooth transition between the first mating portion 201 and the second mating portion 202 ensures the smoothness of the bottom plate 103 of the protective cover 100 during sliding, reduces friction and wear, and prolongs the service life of the protective structure. At the same time, this design also improves the response speed of the protective cover 100 with the movement of the workbench and enhances the overall performance of the system.

[0072] The structural design of the L-shaped protective groove 200 facilitates local maintenance and adjustment. The interior of the groove can be cleaned or the sealing material can be replaced without completely disassembling the protective cover 100, which reduces the complexity and cost of maintenance, reduces downtime, and improves production efficiency.

[0073] The design of the first mating portion 201 and the second mating portion 202 places higher requirements on the manufacturing accuracy of the protective plate 300, but also provides more precise dimensional control to ensure tightness during assembly. By optimizing the design and manufacturing process, the manufacturing accuracy and performance of the protective structure can be greatly improved while controlling costs.

[0074] Further, the protection plate 300 includes: a first section 301, the first section 301 extends along the second direction;

[0075] A second subdivision 302, wherein a first end of the second subdivision 302 is connected to a first end of the first subdivision 301, and the second subdivision 302 extends along a first direction;

[0076] The third section 303 extends along the second direction, a first end of the third section 303 is connected to the second end of the second section 302 , and an end of the third section 303 away from the second section 302 is connected to the first matching portion 201 .

[0077] Specifically, the protection plate 300 forms a more complex three-dimensional protection structure through the design of the first sub-section 301, the second sub-section 302 and the third sub-section 303, which can prevent the graphite dust and other particles from entering the machine tool from all angles. The extension of the first sub-section 301 along the second direction, the extension of the second sub-section 302 along the first direction perpendicular to the first sub-section, and the connection of the third sub-section 303 together constitute a more stable protection frame, which improves the tightness and reliability of the protection.

[0078] The segmented design of the protective plate 300 not only increases the contact area with the protective cover 100, but more importantly, this L-shaped and extended structure effectively disperses the force when the workbench moves, and enhances the strength and stability of the overall structure. This means that in an environment with high load or frequent movement, the protective structure can maintain good sealing performance and avoid protection failure caused by structural deformation or damage.

[0079] Through the precise design and connection of the first section 301, the second section 302 and the third section 303, the smoothness of the protective cover 100 during sliding is ensured, the sliding friction is reduced, the wear of the protective groove 200 and the bottom plate 103 of the protective cover 100 is effectively reduced, the service life of the entire protective structure is extended, and the maintenance frequency is reduced.

[0080] The connection between the third subsection 303 and the first matching section 201 provides an additional sealing space, so that the injected oil or sealing material can be more evenly distributed, thereby improving the use efficiency of the sealing material, reducing material consumption, and lowering operating costs.

[0081] The segmented design of the protection plate 300 places higher demands on manufacturing precision, but at the same time, this modular structure also enhances assembly flexibility and assembly accuracy.

[0082] Further, the distance between the side plate 102 and the second matching portion 202 is 2 mm to 3 mm; and / or,

[0083] The distance between the side plate 102 and the bottom of the protective groove 200 is 5 mm to 6 mm; and / or,

[0084] The length of the second matching portion 202 along the second direction is 7 mm to 8 mm.

[0085] The present invention achieves strict control of the gap by precisely defining the distance between the side plate 102 and the second matching portion 202 as 2mm to 3mm, and the distance between the side plate 102 and the bottom of the protective groove 200 as 5mm to 6mm. These tiny but precise gap designs ensure effective contact between the protective cover 100 and the protective groove 200 in the moving state, while avoiding friction and wear caused by over-tight contact, thereby greatly improving the overall sealing performance and effectively preventing the intrusion of graphite dust.

[0086] The length of the second matching portion 202 along the second direction is set to 7 mm to 8 mm. The selection of this size is based on an in-depth analysis of the motion characteristics of the workbench and the stability of the protective structure. The appropriate length ensures that the protective groove 200 can firmly support the protective cover 100 without affecting the telescopic flexibility of the protective cover 100. This design can not only ensure the stability of the structure, but also adapt to the dynamic changes of the workbench, thereby improving the reliability of the protective structure.

[0087] Precise clearance and size design reduces wear and friction inside the protective structure, reduces maintenance frequency, and thus reduces maintenance costs. At the same time, these optimization measures ensure that the protective plate 300 and the protective cover 100 can still maintain a good sealing effect during long-term operation, effectively preventing graphite dust from contaminating and wearing the internal precision parts, thereby extending the service life of the machine tool.

[0088] Effectively preventing the spread of graphite dust not only protects the key components inside the machine tool, but also significantly improves the operating environment, reduces the potential harm of dust to the respiratory tract of machine tool operators, and improves the safety and health level of the workplace.

[0089] Further, a plurality of protection units 4 are arranged along the extension direction of the component to be protected;

[0090] Along the expansion and contraction direction of the component to be protected, the distance between the bottom of the protection groove 200 and the foundation to be installed gradually increases.

[0091] Further, the component to be protected includes telescopic cylinders that are telescopically arranged one by one, wherein along the extension direction of the telescopic cylinders, the distance between the top plate 101 and the bottom walls of the plurality of telescopic cylinders gradually decreases.

[0092] Furthermore, the distance between the outermost side wall of the telescopic cylinder and the inner side surface of the corresponding side plate 102 is a preset distance.

[0093] The plurality of protection units 4 are arranged along the extension direction of the protected component, forming a sealing structure that can adapt to the gradual extension of the telescopic cylinder. This design ensures that no matter what state the telescopic cylinder is in, the protection groove 200 can fit tightly, effectively preventing the intrusion of graphite dust.

[0094] As the telescopic cylinder is extended, the distance between the top plate 101 and the bottom walls of the multiple telescopic cylinders gradually decreases. This design ensures that the top plate 101 can always maintain proper contact with the telescopic cylinders, avoiding both sealing failure caused by too far a distance and friction and wear caused by too close a distance, thereby achieving a perfect balance between dynamic sealing and component protection.

[0095] A preset distance is maintained between the outermost wall of the telescopic cylinder and the corresponding inner side of the side plate 102. This design takes into account the relative movement between the telescopic cylinder and the side plate 102. By controlling this distance, the wear and friction caused by lateral movement are reduced, the service life of the telescopic cylinder and the protective cover 100 is extended, and the maintenance cost is reduced.

[0096] As the telescopic cylinder is extended and retracted, the distance between the bottom of the protective groove 200 and the foundation to be installed changes, and the preset distance between the telescopic cylinder and the side plate 102, together optimize the use efficiency of the sealing material (such as oil). When the telescopic cylinder is extended, the sealing material can be more evenly distributed to form an effective sealing barrier, and when it is retracted, the sealing material will not accumulate excessively, avoiding waste and reducing operating costs.
