Description

Technical Field

[0001] The present invention relates to the technical field of guide vane processing, and particularly to an arc cutting device for guide vanes. Background Art

[0002] A guide vane is a common component in hydrodynamic applications, and its main function is to guide and control the flow direction of a fluid (such as air or water). A guide vane is a blade with a specific shape and structure, used to guide the fluid along the expected path, preventing problems such as the generation of vortices, poor air flow, energy loss, and noise at sharp turns. The main functions of the guide vane are: ensuring that the fluid flows in a predetermined direction, and improving the efficiency and accuracy of fluid transmission. For example, in a ventilation duct system, the guide vane can enable air to smoothly pass through components such as elbows, reducing wind resistance and energy loss; creating a group of air outlets of a limited size, increasing the flow rate and lift of the fluid, ensuring the normal operating state of related equipment, and maintaining the stability of environmental parameters; a reasonably designed and arranged guide vane can make the fluid flow more smoothly, reducing the formation of vortices and turbulence, reducing the impact on the system, and improving the stability and reliability of the system; in a heating, ventilation, and air conditioning (HVAC) system, the guide vane can effectively reduce the noise generated by air flow, improving the comfort of the living or working environment.

[0003] Currently, in the process of processing guide vanes, arc cutting is usually adopted. This can not only precisely control the cutting path and depth, making the cutting size of the guide vane more accurate, enabling precise cutting of complex shapes, ensuring that the shape of the guide vane meets the design requirements, and the cutting surface generated by arc cutting is relatively smooth, reducing the surface roughness of the guide vane. Compared with some traditional cutting methods, such as flame cutting, the heat affected zone of arc cutting is smaller. However, the arc cutting in the existing technology has the following defects:

[0004] 1) Large heat affected zone (HAZ): High temperature causes material oxidation and phase change, reducing mechanical properties;

[0005] 2) Low cutting accuracy: Unstable arc leads to rough cut edges, requiring secondary processing;

[0006] 3) Poor material adaptability: Composite materials are easily ablated, and the cutting efficiency of superalloys is low; Therefore, we propose an arc cutting device for guide vanes to solve this problem. Summary of the Invention

[0051] Two groups of positioning mechanisms are provided. The two slide rails 2 are respectively fixedly installed on one side of the corresponding support frames 302.

[0052] In this embodiment, a guiding rod is fixedly installed inside the fixed frame 301. The sliding seat 307 is slidably sleeved on the outer side of the corresponding guiding rod.

[0053] In this embodiment, the guide vane to be cut is placed between the four positioning frames 201, and then the cylinders 202 are started to drive the four positioning frames 201 to approach the guide vane to achieve positioning. The graphene-boron nitride composite coating is introduced into the cavity by opening the control valve 503, and then the control valve 503 is closed, and the spraying pump 14 is started. The graphene-boron nitride composite coating is drawn out through the feed pipe and sprayed onto the surface of the guide vane through the spraying pipe 1401 to form a coating. The first servo motor 305, the second servo motor 308, and the electric push rod 310 are started by the controller 10. The first servo motor 305 drives the first lead screw 306 to rotate, and drives the translation frame 303 to move back and forth through the threaded cooperation with the sliding seat 307. The second servo motor 308 drives the second lead screw 309 to rotate, and the second lead screw 309 drives the translation plate 304 to move left and right through the threaded cooperation with the translation plate 304. The electric push rod 310 drives the lifting frame 4 to move up and down, so as to drive the lifting frame 4 and the rotating seat 5 to perform three-dimensional movement along the cutting track of the guide vane, and the coating formed on the surface of the guide vane covers the cutting track.

[0054] During the left - right movement of the translation plate 304, it drives the horizontal movement of the outer screw cylinder 902. The rack 901 drives the rotation of the outer screw cylinder 902 through meshing with the gear 905. When the lifting frame 4 remains relatively stationary with respect to the translation plate 304, the outer screw cylinder 902 drives the inner screw cylinder 903 to rotate synchronously and drives the linkage shaft 904 to rotate. When the lifting frame 4 moves up and down relative to the translation plate 304, it can drive the inner screw cylinder 903 to move up and down within the outer screw cylinder 902 and rotate relative to the outer screw cylinder 902, causing the linkage shaft 904 to rotate further. The linkage shaft 904 drives the rotation of the mixing shaft 601 through the cooperation of the one - word plug connector 906 and the socket 603. The mixing shaft 601 drives the mixing paddle 602 to rotate, and the mixing paddle 602 mixes the composite coating;

[0055] The rotation of the mixing shaft 601 drives the rotation of the rotating disk 805 and the first permanent magnet 804. After the first permanent magnet 804 rotates half a turn, the magnetic pole positions at both ends are reversed, thus changing the direction of the magnetic force acting on the two second permanent magnets 802. During the rapid rotation of the rotating disk 805, the magnetic pole positions of the first permanent magnet 804 are constantly reversed, so that the second permanent magnets 802 can be driven to reciprocate through the magnetic attraction cooperation with the first permanent magnet 804, and the vibrating rod 801 is driven to reciprocate, causing the vibrating rod 801 to vibrate the coating on the surface of the guide vane, so that the coating distribution is more compact and fills the micropores on the surface of the guide vane;

[0056] By activating the electromagnet 705 to magnetically attract the iron sheet 704 and drive the locking column 702 to move upward, compressing the compression spring 703, so that the locking column 702 disengages from the card slot. Then start the third servo - motor 501 to drive the mounting shaft 502 and the rotating seat 5 to rotate, making the integrated fiber laser 12 face directly downward. At this time, the locking column 702 aligns with another card slot. Control the electromagnet 705 to power off through the controller 10, so that the locking column 702 moves downward under the action of the compression spring 703 and snaps into the card slot to lock the locking disk 701 and the rotating seat 5. Then start the first servo - motor 305, the second servo - motor 308 and the electric push - rod 310 again to drive the rotating seat 5 and the integrated fiber laser 12 to move along the cutting track of the guide vane, adjust the integrated fiber laser 12 to a wavelength of 1064 nm and a power of 500 - 2000 W, thereby preheating the cutting position of the guide vane and the composite coating. Detect the preheating temperature through the infrared thermometer 13, and control the operating speeds of the first servo - motor 305, the second servo - motor 308 and the electric push - rod 310 in real - time through the controller 10 to adjust the preheating temperature to an appropriate range;

[0057] The electromagnet 705 is activated to magnetically attract the iron sheet 704, causing the locking column 702 to disengage from the card slot. Then, the third servo motor 501 is activated to drive the mounting shaft 502 and the rotating seat 5 to rotate, so that the plasma arc generator 11 faces directly downward. Then, the electromagnet 705 is controlled to power off, causing the locking column 702 to move downward under the action of the compression spring 703 and engage with the card slot to lock the locking disc 701 and the rotating seat 5.
