[0002] The core function of tungsten carbide cutting tools is to perform precision cutting on parts made of various metals or cemented carbide (such as lightweight alloy computer casings). Its high hardness and high wear resistance make it suitable for the high-precision and high-speed machining requirements of equipment such as CNC centers.

[0003] In related technologies, traditional tungsten carbide tool processing mainly relies on manual operation or semi-automated equipment. Currently, the common tungsten carbide tool processing solutions in the industry mainly include the following two types: one is to use a traditional lathe combined with manual grinding, which has the advantage of low equipment cost, but the disadvantages of poor processing accuracy and low efficiency; the other is to use a general-purpose CNC milling machine for processing, which improves accuracy, but the programming is complex, tool changes are frequent, and processing efficiency is affected.

[0004] The existing tungsten carbide tool processing has the following problems: manual operation has low processing efficiency, and the processing accuracy is greatly affected by human factors, resulting in poor consistency; general CNC milling machine programming is complicated and requires frequent tool changes, which requires high technical skills from operators and makes it difficult to meet the high-efficiency production needs of customized tools. Summary of the Invention

[0006] The tungsten carbide tool precision machining center for processing lightweight alloy computer casings provided in this application adopts the following technical solution: A precision machining center for processing lightweight alloy computer casings using tungsten carbide tools includes a support mechanism, a cutting execution mechanism, a feed drive mechanism, a CNC system, and auxiliary support mechanisms. The support mechanism supports other mechanisms and provides an installation reference, and includes a machine tool and a column mounted on the ground. The auxiliary support mechanisms include a cooling assembly and a chip blowing assembly. The CNC system communicates with other mechanisms via a bus interface and can recognize externally input tool shape drawings through a built-in algorithm program, and control other mechanisms to collaboratively complete the milling process of the tungsten carbide blank.

[0007] By adopting the above technical solutions, relying on the intelligent path planning and multi-mechanism bus collaborative control of the CNC system, the automated high-precision milling and forming of tungsten steel tool blanks has been realized. It can accurately reproduce the design outline of the tool shape drawing, ensure the tool size and position accuracy, effectively reduce manual intervention, improve processing efficiency, and provide reliable equipment support for the batch and stable production of tungsten steel tools for processing lightweight alloy computer shells.

[0008] Preferably, the CNC system includes an analytical algorithm unit, a path planning unit, and a closed-loop control unit; the analytical algorithm unit supports parsing tool shape drawings in various formats such as DXF and STEP, and can convert the geometric features of the drawings into a digital coordinate set; the milling path planning unit can automatically generate layered milling paths and cutting parameter sequences based on the digital coordinate set and the mechanical properties of the tungsten steel blank; the closed-loop control unit can convert the instructions output by the path planning unit into action signals for other mechanisms.

[0009] By adopting the above technical solution, and relying on the collaborative operation of multiple units of the CNC system, efficient parsing and digital conversion of multi-format tool drawings are achieved. Furthermore, it can generate customized layered milling paths and cutting parameters by combining the mechanical properties of tungsten steel blanks, and ensure the precise synchronization of the actions of each actuator, effectively improving the forming accuracy and contour reproduction of tungsten steel tools.

[0010] Preferably, the cutting actuator includes a clamping table and a spindle unit arranged opposite to each other; the spindle unit is slidably mounted on the column via a Z-axis linear module, and the clamping table is located in the working area of ​​the machine tool to fix the tungsten steel billet and to achieve X / Y axis movement through the feed drive mechanism.

[0011] By adopting the above technical solution, the X / Y axis movement of the clamping table and the Z axis sliding of the spindle unit form a coordinated cutting motion, which can complete the complex curved surface machining of tungsten steel blanks through multi-axis linkage control, and has both repeatability and stability.

[0012] Preferably, the spindle unit is an electric spindle, the main body of which is integrally machined from a high-rigidity alloy material and has an axially extending mounting cavity; the mounting cavity is fitted with a high-precision combined bearing and an internal cooling channel; the output end of the spindle unit is connected to a cylindrical tool holder, and multiple annular tool discs with different outer diameters and thicknesses are inserted and fixed on the tool holder at intervals.

[0013] By adopting the above technical solutions, the high-rigidity alloy body of the electric spindle ensures load-bearing and vibration resistance, and the high-precision combined bearing components in its mounting cavity ensure the spindle rotation accuracy; the internal cooling channel synchronously delivers cooling medium to reduce the risk of high-temperature deformation or tool breakage; the multi-specification annular cutter head on the output end tool holder can perform layered milling of tungsten steel billets according to parameter requirements without frequent tool changes.

[0014] Preferably, the feed drive mechanism adopts a cross feed slide, which is composed of X-axis and Y-axis linear modules in a cross combination; the clamping table is fixed on the worktable of the cross feed slide, and the nozzles of the cooling component and the chip blowing component are respectively facing the clamping area at the front end of the clamping table and the upper surface of the worktable.

[0015] By adopting the above technical solution, the clamping table can achieve high-precision and smooth X / Y axis linkage displacement, which, together with the sliding of the spindle unit in the Z-axis direction, forms a stable three-axis coordinated cutting motion. The cooling component and the chip blowing component respectively deliver cooling medium and chip removal airflow to directionally cool the cutting area and the tool, and quickly remove residual impurities such as machining chips, reducing the occurrence of chips scratching the surface of the workpiece or affecting the feed accuracy of the slide table.

[0016] Preferably, it also includes an automatic loading and unloading assembly, which includes a robotic arm and a conveyor belt. The robotic arm is disposed outside the support mechanism, and the conveyor belt is connected to the clamping table and the gripping end of the robotic arm.

[0017] By adopting the above technical solution, the traditional manual loading and unloading operation is replaced, realizing the automated flow of tungsten steel billet loading and finished product unloading. This reduces the labor intensity of operators and the positioning deviations and collision damage that may occur during manual clamping and unloading, indirectly improving the consistency of billet clamping and the surface quality of finished cutting tools.

[0018] Preferably, it also includes an online measurement component, which includes a three-dimensional sensor and a compensation module. The three-dimensional sensor is located near the cutting actuator and faces the machining surface of the tungsten steel billet. The compensation module is connected to the CNC system signal to correct machining deviations.

[0019] By adopting the above technical solution, the three-dimensional sensor can perform real-time three-dimensional detection of the tungsten steel machining surface during the processing, so as to accurately capture the machining errors such as the size deviation and contour deformation of the blank. The detection deviation data is quickly converted into machining correction instructions through the compensation module, thereby adjusting the milling path or cutting parameters in real time, realizing dynamic compensation of machining errors, and ensuring that the tool form and position tolerance strictly conforms to the design standards.

[0020] Preferably, it also includes a protective cabin for enclosing the processing area, with a door movably installed on its side wall. The door is equipped with an observation window and a handle. The observation window is made of a splash-proof, rigid, transparent material, and its visible range covers the processing area.

[0021] By adopting the above technical solutions, the protective cabin can form a fully enclosed protection for the processing area, effectively blocking the splashing of metal chips and cooling media during the milling process; the observation window allows operators to monitor the milling status of the tool and the progress of the blank forming in real time, and the handle assists in the convenient opening and closing of the cabin door, which together improves the workshop working environment and creates a safe and standardized processing area.

[0022] Preferably, the inner wall of the protective cabin is covered with a sound insulation layer, which is made of sound-absorbing cotton or damping sound insulation board.

[0023] By adopting the above technical solutions, the sound insulation layer can effectively absorb and weaken the high-frequency noise generated by the cutting tool cutting the tungsten steel billet during the milling process, reduce noise pollution, and improve the safety protection and environmental adaptability of the whole machine.

[0024] Preferably, the tungsten carbide tool precision machining center for machining lightweight alloy computer casings described above is characterized by comprising the following machining steps: S1: Ensure the tungsten carbide billet is securely clamped; S2: Import the tool shape drawing into the CNC system or input the machining parameters; S3: The CNC system automatically generates a machining program and simulates the machining path; S4: Start machining; the CNC system, in coordination with each mechanism, automatically executes the machining program. S5: The machine will automatically stop after processing and the finished tungsten carbide tool will be removed.

[0025] By adopting the above technical solutions, the standardized processing steps are deeply adapted to the equipment hardware structure, which not only ensures the processing accuracy and quality stability of a single tool, but also improves the standardization and efficiency of batch processing. At the same time, it lowers the technical threshold for operators, providing a reliable process guarantee for the large-scale and standardized production of tungsten steel tools for processing lightweight alloy computer shells.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. This device relies on the intelligent path planning and multi-mechanism bus collaborative control of the CNC system to realize the automated high-precision milling and forming of tungsten carbide tool blanks. It can accurately reproduce the design outline of the tool shape drawing, ensure the tool size and position accuracy, effectively reduce manual intervention, improve processing efficiency, and provide reliable equipment support for the batch and stable production of tungsten carbide tools for processing lightweight alloy computer shells. 2.

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0033] This application discloses a tungsten carbide tool precision machining center for processing lightweight alloy computer casings. (Refer to...) Figure 1 A precision machining center for tungsten steel tools used in the processing of lightweight alloy computer casings includes a support mechanism 2, a cutting execution mechanism 4, a feed drive mechanism 3, a CNC system, and an auxiliary support mechanism 5. The support mechanism 2 is used to support other mechanisms and provide an installation reference. It includes a machine tool 21 mounted on the ground and a column 22. The auxiliary support mechanism 5 includes a cooling assembly 51 and a chip blowing assembly 52. ​​The CNC system (not shown in the figure) communicates with other mechanisms through a bus interface. It can recognize externally input tool shape drawings through built-in algorithm programs and control other mechanisms to collaboratively complete the milling process of tungsten steel blanks.

[0034] Correspondingly, the workflow of this device is centered on the CNC system as the core command unit. First, the operator imports the shape drawing of the target tungsten carbide tool into the CNC system. The system completes the drawing information recognition and milling path planning through the built-in algorithm, and then sends collaborative instructions to each actuator through the bus interface. The machine tool 21 and column 22 provide a stable installation benchmark and bearing platform for processing, ensuring that each mechanism maintains the preset spatial posture. At the same time, the tungsten carbide blank to be processed is fixed at the designated station of the machine tool 21, completing the positioning preparation before processing.

[0035] Furthermore, after the tungsten steel blank is fixed, the feed drive mechanism 3 drives the cutting actuator 4 to complete the spatial displacement and attitude control according to the instructions, and simultaneously drives the cutting actuator 4 to carry out high-precision milling operations, gradually forming the tool profile that meets the requirements of the drawing; throughout the machining process, the cooling component 51 continuously cools the cutting area and the tool, and the chip blowing component 52 removes metal chips in real time; after the milling operation is completed, the CNC system controls each mechanism to reset, and finally completes the machining and forming of the tungsten steel tool.

[0036] Therefore, relying on the intelligent path planning and multi-mechanism bus collaborative control of the CNC system, automated and high-precision milling of tungsten carbide tool blanks is achieved. This accurately reproduces the design outline of the tool shape drawing, ensuring the tool's dimensional and positional accuracy. The auxiliary support mechanism 5 effectively reduces the risk of tool and blank deformation due to high temperatures during processing, and reduces scratches on the machined surface from metal chips and abnormal tool wear. This improves the processing pass rate and forming quality of tungsten carbide tools, and extends the service life of key equipment components such as tools. This device comprehensively reduces manual intervention and improves processing efficiency, providing reliable equipment support for the batch and stable production of tungsten carbide tools used for processing lightweight alloy computer casings (not limited to such accessories).

[0037] Specifically, refer to Figure 2 The CNC system includes an analytical algorithm unit, a path planning unit, and a closed-loop control unit. The analytical algorithm unit supports the analysis of tool shape drawings in various formats such as DXF and STEP, and can convert the geometric features of the drawings into a digital coordinate set. The milling path planning unit can automatically generate layered milling paths and cutting parameter sequences based on the digital coordinate set and the mechanical properties of tungsten steel blanks. The closed-loop control unit can convert the instructions output by the path planning unit into action signals for other mechanisms.

[0038] Therefore, the analytical algorithm unit can efficiently analyze and digitize multi-format tool shape drawings; the path planning unit, by combining the mechanical properties of tungsten carbide blanks, generates customized layered milling paths and cutting parameters, which can reduce idle travel time by 30%-50% and supports various optimized paths such as contour cutting and helical cutting; the closed-loop control unit is used to ensure the precise synchronization of the actions of each actuator. Through the coordinated operation of these three core units, the system achieves seamless conversion from design drawings to finished parts, effectively improving the forming accuracy and contour reproduction of tungsten carbide tools, and providing reliable technical support for precision machining.

[0039] On the other hand, refer to Figure 3-4The cutting actuator 4 includes a clamping table 41 and a spindle unit 42 mounted opposite each other. The spindle unit 42 is slidably connected to the column 22 via a Z-axis linear module. The clamping table 41 is located in the working area of ​​the machine tool 21 and is used to fix the tungsten steel billet. It moves along the X / Y axes through the feed drive mechanism 3.

[0040] Therefore, the spindle unit 42 is directly integrated onto the column 22, shortening the force transmission path and enhancing system rigidity. Axial feed is achieved through vertical movement along the column 22 via the Z-axis module. Simultaneously, the high-speed rotation of the spindle unit 42 precisely adjusts the cutting depth. The tungsten steel billet is securely fixed by the clamping table 41, resisting cutting vibrations during the machining of high-hardness materials and ensuring machining stability. It also achieves bidirectional movement in the horizontal plane via the feed drive mechanism 3, thus forming a three-dimensional machining path. The X / Y axis movement of the clamping table 41 and the Z-axis sliding of the spindle unit 42 form a coordinated cutting motion, enabling the machining of complex curved surfaces of the tungsten steel billet through multi-axis linkage control, combining repeatability and stability.

[0041] Specifically, the spindle unit 42 is an electric spindle, the main body of which is integrally machined from high-rigidity alloy material and has an axially through-hole for mounting cavity; the mounting cavity is fitted with high-precision combined bearing components and an internal cooling channel (not shown in the attached figure); the output end of the spindle unit 42 is connected to a cylindrical tool holder 421, and multiple annular tool discs 422 with different outer diameters and thicknesses are inserted and fixed on the tool holder 421 at intervals.

[0042] Correspondingly, the electric spindle integrates the motor and spindle into one unit, providing high-speed rotation. Combined with high-precision combined bearing components (such as angular contact ball bearings or ceramic bearings), it ensures smooth operation at the output end, reduces vibration, and achieves micron-level machining accuracy. The one-piece body made of high-rigidity alloy material enhances the overall torsional rigidity and resists cutting force deformation, making it suitable for efficient cutting of high-hardness materials such as tungsten steel. The internal cooling channel uses circulating coolant (such as oil or water-based coolant) for forced heat dissipation, quickly removing the heat generated by the high-speed operation of the spindle, reducing accuracy drift caused by thermal expansion, and ensuring the reliability of long-term continuous machining. The multi-specification annular cutter head 422 on the tool holder 421 at the output end can perform layered milling of tungsten steel blanks according to parameter requirements, without frequent tool changes, and allows multiple processes to be completed in one clamping. It is suitable for continuous operation of roughing, finishing, or complex contours, further improving machining efficiency and process adaptability.

[0043] On the other hand, the feed drive mechanism 3 adopts a cross feed slide, which is composed of X-axis and Y-axis linear modules in a cross combination; the clamping table 41 is fixed on the worktable of the cross feed slide, and the nozzles of the cooling component 51 and the chip blowing component 52 are respectively facing the clamping area at the front end of the clamping table 41 and the upper surface of the worktable.

[0044] Therefore, the cross slide adopts an integrated base and linear guide rail, which can effectively resist the vibration caused by cutting force and ensure smooth movement during heavy-duty cutting. It drives the ball screw through a servo motor to drive the clamping table 41 to achieve high-precision and smooth X / Y axis linkage displacement, and supports linear, circular and curved path interpolation. Combined with the sliding of the spindle unit 42 in the Z-axis direction, it forms a stable three-axis coordinated cutting motion to meet the multi-face processing requirements of tungsten steel billets (such as contour milling, drilling, etc.) and reduce repeated clamping errors.

[0045] Meanwhile, the cooling component 51 and the chip blowing component 52 are used to deliver cooling medium (such as cutting fluid) and chip removal airflow to specific points, respectively. By rapidly cooling the cutting area and the tool, the risk of high-temperature deformation or tool breakage is reduced, and the machining debris in the clamping area and residual impurities on the worktable are efficiently removed, reducing the occurrence of debris scratching the workpiece surface or affecting the feed accuracy of the slide table.

[0046] In addition, an automatic loading and unloading assembly 6 is included. The automatic loading and unloading assembly 6 comprises a robotic arm 61 and a conveyor belt 62. The robotic arm 61 is mounted on the outside of the support mechanism 2, and the conveyor belt 62 connects the clamping table 41 and the gripping end of the robotic arm 61. Through coordinated operation, the two components replace traditional manual loading and unloading operations, achieving automated flow of tungsten steel billet loading and finished product unloading. This reduces the labor intensity of operators and the potential positioning deviations and collision damage that may occur during manual clamping and unloading, indirectly improving the consistency of billet clamping and the surface quality of the finished cutting tools.

[0047] Furthermore, the conveyor belt 62 precisely connects the clamping table 41 with the robot gripping end, ensuring smooth material flow, reducing the waiting time for manual handling, effectively shortening the overall processing cycle of a single tool, and improving the continuous operation capability and batch production efficiency of the equipment.

[0048] In summary, the automatic loading and unloading component 6 works in synergy with the existing three-axis linkage cutting, directional cooling chip removal, and CNC precision control mechanisms to construct a fully automated closed loop from blank entry to finished product exit. This further improves the overall stability and finished product qualification rate of tungsten carbide tool processing, while reducing direct contact between manual labor and the processing area, optimizing operational safety in the production process, and providing comprehensive equipment support for the large-scale, unmanned production of tungsten carbide tools for lightweight alloy computer casings.

[0049] Specifically, it also includes an online measurement component 7, which includes a three-dimensional sensor and a compensation module. The three-dimensional sensor is installed near the cutting actuator 4 and faces the machining surface of the tungsten steel billet. The compensation module is connected to the CNC system signal to correct machining deviations.

[0050] Correspondingly, the 3D sensor can perform real-time 3D detection of the tungsten carbide machining surface during the processing to accurately capture machining errors such as dimensional deviations and contour deformation of the blank. Compared with the traditional offline sampling inspection mode, it effectively reduces the waste of materials and time caused by discovering substandard accuracy only after the machining is completed. The compensation module and the CNC system achieve signal linkage, which can quickly convert the deviation data detected by the 3D sensor into machining correction instructions, adjust the milling path or cutting parameters in real time, realize dynamic compensation of machining errors, thereby improving the dimensional accuracy and contour consistency of the finished tungsten carbide tool, and ensuring that the tool's form and position tolerances strictly meet the design standards.

[0051] Corresponding to the above process, a protective cabin 1 is also included. The protective cabin 1 is used to enclose the processing area. A door 11 is movably installed on its side wall. The door 11 is equipped with an observation window 111 and a handle 12. The observation window 111 is made of a splash-proof hard transparent material, and its visible range covers the processing area.

[0052] Therefore, the protective chamber 1 can form a fully enclosed protection for the processing area, effectively blocking the splashing of metal chips and cooling media during the milling process, reducing personal injury to operators from chips and media, effectively improving the workshop working environment, constructing a safe and standardized processing area, and providing a reliable protective barrier for the safety and stability of the overall production process.

[0053] Furthermore, operators can monitor the milling status of the cutting tool and the progress of the blank forming in real time through the observation window 111 without opening the hatch 11. This ensures safety during the observation process and reduces the risk of dust and debris entering the processing area due to frequent door opening, which could affect milling accuracy. The handle 12 of the hatch 11 is ergonomically designed to allow for smooth opening and sealing, making it easy for staff to quickly enter the processing area to perform blank adjustment, tool maintenance, and other operations when the equipment is stopped.

[0054] Meanwhile, in this embodiment, the inner wall of the protective chamber 1 is lined with a sound-absorbing cotton layer, which can effectively absorb and weaken the high-frequency noise generated by the high-speed rotation of the electric spindle and the cutting of tungsten steel billets during the milling process. Combined with the closed structure of the protective chamber 1, it forms a dual sound insulation mechanism of "physical isolation + sound absorption and noise reduction", reducing the transmission of processing noise to the outside space, effectively improving the overall sound environment of the workshop, reducing the hearing damage caused by long-term high-decibel noise to operators, and improving the level of work comfort and occupational health protection. At the same time, the sound insulation layer also provides a certain degree of protection for the inner wall of the protective chamber 1, reducing the direct corrosion of the inner wall of the chamber by the cooling medium condensate or metal shavings, and extending the service life of the protective chamber 1.

[0055] Corresponding to the above process, a tungsten carbide tool precision machining center for machining lightweight alloy computer casings includes the following machining steps: S1: Ensure the tungsten carbide billet is securely clamped. In this step, it is required to securely clamp the tungsten carbide billet to lay a stable positioning foundation for subsequent high-precision milling and reduce processing deviations caused by billet loosening from the source.

[0056] S2: Import the tool shape drawing into the CNC system or input the machining parameters; this step eliminates omissions or errors in manual instruction transmission, provides accurate data support for the automatic generation of machining programs, and improves process adaptability.

[0057] S3: The CNC system automatically generates machining programs and simulates machining paths; it can verify the rationality of machining trajectories in advance, effectively avoid potential machining faults such as path conflicts and overcuts, and reduce trial cutting losses and rework costs.

[0058] S4: Start machining. The CNC system coordinates with various mechanisms to automatically execute the machining program. In this step, the CNC system combines and controls the coordinated operation of various mechanisms to accurately complete the automated forming of tungsten carbide tools, ensuring the dimensional accuracy and contour consistency of the finished product. No manual intervention is required throughout the process, which not only improves machining efficiency but also ensures that the tool dimensional accuracy and contour reproduction meet the design requirements, reducing human error.

[0059] S5: Automatic shutdown after processing, remove the tungsten carbide tool. The automatic shutdown function in this step ensures that all mechanisms are accurately reset after processing, reducing energy waste and safety risks caused by idling or malfunctions; at the same time, a smooth shutdown can also reduce the occurrence of the equipment hitting the finished product due to inertia, ensuring the good surface quality of the finished product.

[0060] The implementation principle of the tungsten carbide tool precision machining center for processing lightweight alloy computer casings in this application embodiment is as follows: This device relies on the intelligent path planning and multi-mechanism bus collaborative control of the CNC system to achieve automated, high-precision milling of tungsten carbide tool blanks. It can accurately reproduce the design outline of the tool shape drawing, ensuring the tool's dimensional and positional accuracy. The auxiliary support mechanism 5 effectively reduces the risk of tool and blank deformation caused by high temperatures during processing, and reduces scratches on the machined surface by metal chips and abnormal tool wear. This improves the processing qualification rate and forming quality of tungsten carbide tools, and extends the service life of key equipment components such as tools. Therefore, it comprehensively reduces manual intervention while improving processing efficiency, providing reliable equipment support for the batch and stable production of tungsten carbide tools used for processing lightweight alloy computer casings (not limited to such accessories).
