When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0057] Please refer to Figures 1 to 7,, The present invention discloses a metal cutting device for facilitating chip cleaning, which includes a cutting platform 1, a tool driving mechanism 2 and a chip processing system 3. It can be understood that through its chip processing system 3, the problem that chips fly randomly and are not easy to clean during the cutting process of metal tools at present can be effectively improved.

[0058] Specifically, the workpiece to be cut is located on the cutting platform 1, and metal cutting of the tool is achieved through the tool driving mechanism 2. It should be noted that the tool driving mechanism 2 can be a multi-axis linkage machine tool or a vertical servo cutting machine table, but is not limited thereto, and can be determined according to actual needs. In this embodiment, the tool driving mechanism 2 is a vertical numerical control machine tool.

[0059] In some embodiments, the chip processing system 3 includes a blowing device 31 and a negative pressure collection device 33 symmetrically arranged on both sides of the processing area of the cutting platform 1. Among them, during the process of the tool driving mechanism 2 cutting the workpiece, the chips can be blown into the negative pressure collection device 33 through the blowing device 31.

[0060] Furthermore, the blowing device 31 can include a main air flow nozzle 310 and a swing driving mechanism 320. The main air flow nozzle 310 realizes periodic swinging in the horizontal direction through the swing driving mechanism 320, with a swing frequency of 5 - 20 Hz and a swing angle range of ±15° - ±45°.

[0061] Specifically, the blowing device 31 further includes a housing 301, which is located on one side of the cutting platform 1. The main air flow nozzle 310 and the swing driving mechanism 320 are located inside the housing 301 to blow away the waste chips on the cutting platform 1 through the main air flow nozzle 310.

[0062] Furthermore, the swing driving mechanism 320 includes a first base 321, a second base 323, a driving vane 326 and a driving pipeline 327. Specifically, the first base 321 is fixedly connected to the housing 301 of the blowing device 31. A rotating block 322 is rotatably connected to the first base 321, and an arc-shaped limiting guide rail 3220 is provided on the rotating block 322. The second base 323 is located on one side of the first base 321 and is fixedly connected to the housing 301 of the blowing device 31. A driving block 324 is rotatably connected to the second base 323. The driving block 324 includes an extension portion 3240, and a limiting rod 325 is fixedly connected to the extension portion 3240, and the limiting rod 325 is slidably connected in the limiting guide rail 3220. Therefore, when the driving block 324 rotates, the rotating block 322 can be driven to rotate through the limiting rod 325. The main air flow nozzle 310 is connected to the rotating block 322 and swings reciprocally with the driving block 324.

[0063] Further, the driving blade 326 is fixedly connected to the driving block 324; and the driving pipeline 327 includes an opening for jetting gas, and the gas jetted from the opening can drive the driving block 324 to rotate through the driving blade 326. The driving blade 326 is rotated by the blowing of the gas to provide the power for the rotation of the rotating block 322. The gas that drives the rotation of the driving blade 326 can also be used to blow the cutting debris on the cutting platform 1.

[0064] Auxiliary air holes 311 are provided on both sides of the air flow channel of the main air flow nozzle 310. The jetting direction of the auxiliary air holes 311 forms an angle of 30° - 60° with the main air flow and inclines towards the surface of the cutting platform 1, forming an anti-splash air curtain covering both sides of the main air flow. Moreover, the center line of the swinging trajectory of the main air flow nozzle 310 coincides with the axis of the suction port of the negative pressure collecting device 33, and the swinging air flow and the negative pressure suction cooperate to form a dynamic sweeping gas-solid transmission channel. Through the cooperation of the 30° - 60° angle air curtain formed by the auxiliary air holes 311 and the main air flow, a double-layer protection barrier is constructed above the cutting area, effectively blocking the splashing and spreading of the cutting debris in all directions. The inclined jetting angle enables the air flow to form a directional purging effect, controlling the splashed objects within the range of the surface of the cutting platform 1.

[0065] Further, a sandwich layer 3011 is provided on the housing 301 of the blowing device 31, and the auxiliary air holes 311 are located within the sandwich layer 3011. Among them, the air flow pressure of the auxiliary air holes 311 is 1 / 3 - 1 / 5 of the pressure of the main air flow nozzle 310, and a vortex generator 3110 is provided inside the auxiliary air holes 311 to cause the air curtain air flow to generate a radial vortex motion, and the vortex angular velocity is 50 - 150 rad / s.

[0066] It can be understood that the sandwich layer 3011 of the housing 301 forms a closed air flow channel with a thickness of 8 - 12 mm, controlling the fluctuation of the intake air pressure of the auxiliary air holes 311 within ±2%, ensuring the uniform distribution of the air curtain air flow. At the same time, by setting the air pressure of the auxiliary air holes 311 to 1 / 4 of the main air flow, it can not only avoid the air curtain air flow from strongly interfering with the direction of the main air flow, but also form a stable low-turbulence laminar flow barrier. In actual aluminum alloy cutting tests, the escape amount of debris outside the air curtain is reduced from 12 g / min in the traditional design to 0.5 g / min, and the suppression efficiency is increased by 95%.

[0067] At the same time, since the vortex generator 3110 adopts a spiral guide vane structure, it causes the air curtain air flow to generate a radial vortex and form a micro-vortex cluster with a diameter of 0.5 - 1.5 mm. Through the centripetal acceleration of the vortex air flow, a radial restraint force can be applied to the splashing debris to guide it to the main air flow area. Moreover, the centrifugal effect generated by the vortex air flow can also separate the cutting fluid attached to the surface of the debris, reducing the moisture content of the debris entering the negative pressure collecting device 33 by 60% and improving the subsequent solid-liquid separation efficiency.

[0068] Based on the core design of voltage stabilization in the interlayer 3011, vortex constraint, and low-pressure high efficiency, it breaks through the bottlenecks of traditional air curtain technology, such as high energy consumption, uneven coverage, and easy blockage, achieving a leapfrog improvement in chip control, energy efficiency ratio, and environmental friendliness, and is especially suitable for cutting processing scenarios with high precision and high cleanliness requirements.

[0069] In some embodiments, the negative pressure collection device 33 includes a cyclone separation module 331, a vibration screening module 332, and a vacuum generating mechanism 333 arranged in sequence along the airflow direction inside it.

[0070] Specifically, the cyclone separation module 331 includes a spiral guide plate 3310 and a conical aggregate hopper 3311. A solid outlet 3313 controlled by a rotary valve 3312 is connected to the bottom of the conical aggregate hopper 3311. The spiral lift angle of the spiral guide plate 3310 is 40° - 50°, and the surface roughness Ra ≤ 0.8 μm. The taper angle of the conical aggregate hopper 3311 is 55° - 65°, and the inner wall is coated with a polyurethane wear-resistant coating. Elastic sealing strips are provided at the blade gaps of the rotary valve 3312.

[0071] It can be understood that by adopting the combined structure of the spiral guide plate 3310 and the conical aggregate hopper 3311 in the cyclone separation module 331, where the spiral guide plate 3310 is set with an optimized spiral lift angle of 40° - 50° and combined with the precision machining process with a surface Ra ≤ 0.8 μm, the probability of chip adhesion is significantly reduced while ensuring the efficient rotation of the airflow. The conical aggregate hopper 3311 is designed with a taper angle of 55° - 65°. The polyurethane wear-resistant coating on the inner wall can withstand the impact of high-speed particles. Combined with the elastic sealing strip structure of the bottom rotary valve 3312, the airtightness of the system is maintained while realizing continuous discharging. This module achieves efficient separation through the spiral guide plate 3310.

[0072] During the actual cleaning process, the airflow containing metal chips enters the cyclone separation chamber tangentially and forms a downward swirl along the spiral guide plate 3310. Large particle chips are thrown towards the wall under the action of centrifugal force, descend through the conical aggregate hopper 3311, and are intermittently discharged by the rotary valve 3312.

[0073] In some embodiments, the vibration screening module 332 is internally provided with an inclined ultrasonic vibrating screen 3320. A liquid accumulation tank 3321 with a guiding slope is arranged below the ultrasonic vibrating screen 3320. The liquid accumulation tank 3321 is connected to an external recovery pipeline through a solenoid valve 3323; and a silencing and purification component 3330 is provided at the exhaust end of the vacuum generating mechanism 333, and a silencing cotton layer 3331 and an electrostatic adsorption filter element 3332 are integrated inside.

[0074] Specifically, the vibration screening module 332 adopts the structure of an inclined ultrasonic vibration screen 3320. By optimizing the cooperation between the inclination angle and the ultrasonic vibration at a specific frequency, the screening rate of the ultrasonic vibration screen 3320 can be increased by more than 30%, while effectively preventing material agglomeration and blockage. It should be noted that the working frequency of the ultrasonic vibration screen 3320 is 25 - 40 kHz, and the amplitude is 5 - 20 μm. Among them, the vibration direction of the ultrasonic vibration screen 3320 forms an angle of 15° - 30° with the inclination direction of the ultrasonic vibration screen 3320, and the mesh number gradient of the ultrasonic vibration screen 3320 is set as a three-layer structure of 80 meshes, 200 meshes, and 400 meshes.

[0075] The diversion slope liquid accumulation tank 3321 designed below the ultrasonic vibration screen 3320, in cooperation with the external recovery pipeline controlled by the solenoid valve 3323, can achieve the immediate separation and recovery of liquid and solid, and keep the screening environment dry and clean. Further, the diversion slope of the liquid accumulation tank 3321 is 3° - 8°, and a capacitive liquid level sensor 3322 is provided at the bottom of the tank. Therefore, when the liquid level reaches the set height, the solenoid valve 3323 automatically opens and triggers the vacuum generating mechanism 333 to decelerate to 60% - 80% of the rated speed.

[0076] The sound absorption and purification component 3330 integrated at the exhaust end of the vacuum generating mechanism 333 controls the operating noise below 75 dB through the sound absorption cotton layer 3331, and uses the electrostatic adsorption filter element 3332 to purify the discharged gas at the PM2.5 level, with a purification efficiency of 99.6%.

[0077] Further, the sound absorption cotton layer 3331 is composed of gradient density glass wool, and the density ranges from 80 kg / m at the inlet end 3 to 120 kg / m at the outlet end. Among them, the plate spacing of the electrostatic adsorption filter element 3332 is 5 - 8 mm, and the applied voltage is 8 - 12 kV.

[0078] It can be understood that through the triple design of ultrasonic anti-blocking technology, liquid-solid separation and recovery, and multi-stage purification and noise reduction, green and clean production is achieved while ensuring the screening accuracy.

[0079] In an embodiment, the metal cutting tool device for facilitating chip cleaning provided by the present invention may further include an intelligent control module. The intelligent control module can real-time monitor the pressure value in the air flow channel through a pressure sensor, and dynamically adjust the following parameters based on a preset adjustment comparison table. Specifically, the parameters that can be dynamically adjusted at least include the swing frequency and angle of the main air flow nozzle 310, the rotation speed of the vacuum generating mechanism 333, and the amplitude of the ultrasonic vibration screen 3320.

[0080] In order to improve the response effect of the intelligent control module, the adjustment response time of the intelligent control module ≤ 100 ms, and the pressure fluctuation is within ±5%.

[0081] Specifically, it is allowable to arrange three groups of piezoelectric sensors at the inlet of the air flow channel, in the middle part, and at the inlet of the negative pressure collection device 33. A vibration sensor is arranged on the ultrasonic vibration mesh 3320 to monitor the amplitude deviation. And a rotational speed encoder is installed at the end of the motor shaft of the vacuum generating mechanism 333 to provide real-time feedback on the rotational speed.

[0082] In summary, the present invention discloses a metal cutting device facilitating chip cleaning. By forming a dynamic sweeping field through the high-frequency oscillation of the main air flow nozzle and cooperating with the air curtain at an included angle of 30° - 60° of the auxiliary air holes, the chip removal coverage rate can be greatly improved. By generating micro-vortex clusters through the vortex generator and under the action of the radial binding force and centrifugal effect, the moisture content of the chips can be effectively reduced, improving the subsequent processing efficiency. At the same time, through the design that the axis of the main air flow coincides with the axis of the negative pressure suction port and cooperating with the 40° - 50° lift angle of the spiral deflector, a spiral gas-solid transmission channel is formed, greatly improving the solid-liquid separation effect to break through the local blind area of the traditional fixed suction nozzle. Therefore, it can effectively improve the problems in the current metal cutting process, such as the limited air flow coverage range, easy lateral splashing of chips, low separation efficiency, and difficulty in achieving high-efficiency solid-liquid separation.
