Description

Technical Field

[0001] This utility model belongs to the field of graphite crucible processing technology, specifically relating to a graphite crucible end cutting and shaping mechanism. Background Technology

[0002] Graphite crucibles, with their excellent high-temperature resistance, corrosion resistance, and good thermal conductivity, have been widely used in many fields such as metallurgy, chemical industry, and semiconductor industry. With the continuous development of related industries, the requirements for the quality and precision of graphite crucibles are also increasing, and the cutting and shaping of the ends is one of the key factors determining the quality of graphite crucibles.

[0003] Traditional graphite crucible end-cutting and shaping processes face two major challenges. First, the cutting process generates a large amount of graphite debris of varying sizes. In the rough grinding stage, the debris size is typically between 50-200 micrometers, appearing as granules or flakes; in the fine grinding stage, the debris size can be as small as 1-50 micrometers, even producing nanoscale dust. These graphite debris pose numerous hazards. From a human health perspective, long-term inhalation of graphite dust can lead to "graphite pneumoconiosis," causing lung inflammation, fibrosis, and other diseases, severely affecting respiratory function. Simultaneously, the dust can irritate the eyes and skin, causing conjunctivitis, dry and itchy skin, and other problems. For processing equipment, fine graphite dust can easily enter precision components such as machine tool guideways and bearings, accelerating mechanical wear and reducing equipment precision and lifespan. Furthermore, graphite dust is conductive, and its accumulation on electrical components can cause short circuits and other malfunctions. In terms of product quality, residual debris can roughen the surface of the crucible, creating pits or impurities. This not only affects the crucible's appearance but also reduces its high-temperature resistance and chemical stability, leading to dimensional deviations and failing to meet the high-precision requirements of the product. Furthermore, graphite dust emissions can pollute the workshop air, failing to meet occupational health and safety and environmental regulations, and even posing a potential risk of dust explosion.

[0004] Secondly, existing graphite crucible end-cutting and shaping equipment has shortcomings in structural design and functional implementation. Some equipment lacks an effective debris collection device, or the collection device is poorly designed, failing to efficiently collect graphite debris of different particle sizes. For example, some equipment uses a simple dust suction hood, but due to the unreasonable position and structure of the hood, it cannot form a uniform negative pressure in the cutting area, resulting in a large amount of debris escaping. Other equipment has an inadequate filtration system, failing to effectively filter the collected debris, easily causing secondary pollution, and the filter elements are inconvenient to replace, affecting the continuous operation of the equipment. Furthermore, the stability and reliability of the equipment need improvement. During the cutting process, the lack of effective control over cutting force and vibration may lead to a decrease in end-cutting accuracy, affecting the overall quality of the graphite crucible. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a graphite crucible end cutting and shaping mechanism, which solves the problem of significant graphite debris hazards in traditional graphite crucible end cutting and shaping technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a graphite crucible end cutting and shaping mechanism, comprising a milling machine frame, on which a cross slide module and a linear module are mounted. A centering fixture is mounted on the cross slide module. A motor, a spindle mechanism, and an air suction assembly are mounted on the slide of the linear module. The air suction assembly includes a main support, on which a motor and a centrifugal fan are mounted. The motor is driven by the centrifugal fan. The air inlet of the centrifugal fan is connected to one end of an air inlet pipe. The other end of the air inlet pipe is connected to a filter. The filter includes a housing. An internally threaded cap is threaded to the bottom of the housing. A filter cylinder is clamped between the internally threaded cap and the housing. A slot connecting the air inlet pipe is opened at the top of the housing inside the filter cylinder. One end of a suction pipe is connected to the side of the housing. The other end of the suction pipe is connected to the side of a dust suction head. The dust suction head is located outside the spindle of the motor and spindle mechanism.

[0007] The beneficial effects of this utility model are as follows: by using a motor, a spindle mechanism, and a filter, graphite debris generated during the cutting process can be collected, thus preventing graphite debris from escaping into the air, polluting the environment, and harming human health.

[0008] To ensure the stability of the filter installation;

[0009] As a further improvement to the above technical solution: a side support is provided on the outside of the air inlet pipe. The side support includes a pipe clamp and a support plate. The pipe clamp is clamped on the outside of the air inlet pipe, and the support plate is fixed to one end of the pipe clamp. The support plate is connected to the slide seat of the cross slide module by bolts.

[0010] The beneficial effects of this improvement are: the air inlet pipe is stably installed on the slide of the cross slide module under the action of the side bracket, thereby providing a stable support for the filter and ensuring the stability of the filter installation.

[0011] To ensure the effectiveness of cartridge filtration;

[0012] As a further improvement to the above technical solution: rubber rings are bonded to both the upper and lower ends of the filter cartridge.

[0013] The beneficial effects of this improvement are: the rubber rings bonded to the upper and lower ends of the filter cartridge undergo elastic deformation after being squeezed by the inner threaded cover, the outer shell and the filter cartridge, effectively sealing the gaps at the connection between the filter cartridge and the outer shell and the inner threaded cover, thus ensuring the effectiveness of the filter cartridge filtration.

[0014] In order for the vacuum head to effectively extract the debris generated during the cutting process;

[0015] As a further improvement to the above technical solution: the suction head is an annular groove structure with an open bottom, and the axis of the suction head is collinear with the axis of the motor and the main shaft of the main shaft mechanism.

[0016] The beneficial effects of this improvement are: when the motor is working, the bottom of the suction head forms a uniform negative pressure around the motor and the main shaft of the main shaft mechanism, effectively sucking up the debris generated during the cutting process.

[0017] To further increase the pressure at the nozzle of the vacuum head;

[0018] As a further improvement to the above technical solution: the inner wall of the vacuum head is a tapered plate structure that is narrow at the top and wide at the bottom.

[0019] The beneficial effect of this improvement is that by reducing the width of the slot at the vacuum head, the airflow velocity at the slot can be effectively increased, thereby improving the suction power of the vacuum head.

[0020] To further improve the suction effect of the motor and spindle mechanism;

[0021] As a further improvement to the above technical solution: the motor is a dual-shaft motor, and the number of centrifugal fans is two, which are arranged opposite to each other on both sides of the motor.

[0022] The beneficial effects of this improvement are: the two sets of centrifugal fans and the filters connected to them can work together to efficiently extract the debris generated during the cutting process.

[0023] To avoid the centrifugal fan's exhaust air affecting the collection of graphite cutting debris;

[0024] As a further improvement to the above technical solution: the air outlet of the centrifugal fan is set vertically upward.

[0025] The beneficial effects of this improvement are: the air outlet of the centrifugal fan is set in the opposite direction to the air inlet of the dust collection head, which effectively avoids the air outlet of the centrifugal fan affecting the collection of graphite cutting debris.

[0026] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0034] Example 1:

[0035] like Figure 1—5 shows a graphite crucible port cutting and shaping mechanism, including a milling machine frame 1. A cross slide module 2 and a linear module 3 are mounted on the milling machine frame 1. A centering fixture 4 is mounted on the cross slide module 2. A motor, spindle mechanism 5, and suction assembly 6 are mounted on the slide of the linear module 3. The suction assembly 6 includes a main support 7. A motor 8 and a centrifugal fan 9 are mounted on the main support 7. The motor 8 is driven by the centrifugal fan 9. The air inlet of the centrifugal fan 9 is connected to one end of an air inlet pipe 10. The other end of the air inlet pipe 10 is connected to a filter 12. The filter 12 includes a housing 121. An internal threaded cover 123 is threadedly connected to the bottom end of the housing 121. The internal threaded cover 123 is connected to the outer... A filter cartridge 122 is sandwiched between housings 121. The top of the outer housing 121 inside the filter cartridge 122 has a slot for connecting to the air inlet pipe 10. One end of the suction pipe 13 is connected to the side of the outer housing 121, and the other end of the suction pipe 13 is connected to the side of the suction head 14. The suction head 14 is located outside the main shaft of the motor and main shaft mechanism 5. Through the use of the motor and main shaft mechanism 5 and the filter 12, graphite debris generated during the cutting process is collected, preventing graphite debris from escaping into the air and polluting the environment and harming human health. A side support 11 is provided on the outside of the air inlet pipe 10. The side support 11 includes a pipe clamp 111 and a support plate 112. The pipe clamp 111 is clamped on the outside of the air inlet pipe 10, and the support plate 112... The support plate 112 is fixed to one end of the pipe clamp 111. The support plate 112 is connected to the slide of the cross slide module 2 by bolts. The air inlet pipe 10 is stably installed on the slide of the cross slide module 2 under the action of the side bracket 11, thereby providing a stable support for the filter 12 and ensuring the stability of the filter 12 installation. Rubber rings are glued to both the upper and lower ends of the filter cartridge 122. After being squeezed by the inner threaded cover 123, the outer shell 121 and the filter cartridge 122, the rubber rings glued to the upper and lower ends of the filter cartridge 122 produce elastic deformation, effectively sealing the gap at the connection between the filter cartridge 122 and the outer shell 121 and the inner threaded cover 123, ensuring the filtration effectiveness of the filter cartridge 122. The dust suction head 14 is an annular groove structure with an open bottom. The axis of the suction head 14 is collinear with the axis of the motor and the main shaft of the main shaft mechanism 5. When the motor 8 is working, the bottom end of the suction head 14 forms a uniform negative pressure around the main shaft of the motor and the main shaft mechanism 5, effectively sucking up the debris generated during the cutting process. The inner wall of the suction head 14 is a tapered plate structure that is narrow at the top and wide at the bottom. By reducing the width of the groove at the suction head 14, the airflow velocity at the groove at the suction head 14 can be effectively increased, thereby increasing the suction power of the suction head 14. The motor 8 is a dual-output shaft motor. There are two centrifugal fans 9, which are arranged opposite each other on both sides of the motor 8. The two sets of centrifugal fans 9 and the filter 12 connected to them can work together to efficiently suck up the debris generated during the cutting process. The air outlet of the centrifugal fan 9 is set vertically upward.The air outlet of the centrifugal fan 9 is positioned opposite to the air inlet of the dust collection head 14, effectively preventing the airflow from the centrifugal fan 9 from affecting the collection of graphite cutting debris.

[0036] The working principle of this technical solution is as follows: The graphite crucible to be processed is placed on the centering fixture 4. Through the operation control panel, the motion parameters of the cross slide module 2 and the linear module 3 are set, such as feed rate and depth of cut. At the same time, according to the cutting process requirements, the spindle speed of the motor and spindle mechanism 5 is set to ensure that the tool can process the crucible port at a suitable cutting speed. The motor 8 is started, driving the centrifugal fan 9 to operate, so that the suction component 6 starts to work. At this time, the centrifugal fan 9 forms a negative pressure around the spindle of the motor and spindle mechanism 5 through the air inlet pipe 10, filter 12, suction pipe 13 and dust suction head 14, forming a high air velocity at the slot opening. The filter 12 uses suction to effectively extract graphite debris generated during the cutting process. The motor and spindle mechanism 5 are started, and the spindle drives the tool to rotate, beginning the cutting and shaping of the graphite crucible port. During the cutting process, the cross slide module 2 and the linear module 3 move according to preset parameters, allowing the tool to precisely cut along the contour of the crucible port. During the cutting process, a large amount of graphite debris is intercepted by the filter 12. After prolonged use, the filter cartridge 122 will become clogged, affecting the dust collection effect. At this time, unscrew the inner threaded cap 123, remove the filter cartridge 122, and clean the graphite debris from the surface and inside of the filter cartridge. If the filter cartridge 122 is damaged or the filtration effect decreases significantly, replace it with a new filter cartridge promptly.
