DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, purposes and effects realized by the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0030] As Figures 1 to 7 shown, the cutting device for processing of the electric heating alloy according to the embodiment of the present application comprises a power box 1 capable of translation, two parallel processing grooves 13 are formed in the front end of the power box 1, a circular saw blade 5 capable of rotation is arranged in the processing groove 13, two electric telescopic rods 7 capable of translation are arranged at the front end of the power box 1, a clamping arm 24 is fixedly connected to the moving end of the electric telescopic rod 7, a pressing block 25 is arranged at the front end of the clamping arm 24, a clamping seat 21 horizontally arranged is fixedly connected between the bottom of the clamping arm 24 and the pressing block 25, a cutting groove 27 is formed in the middle part of the clamping arm 24 and the pressing block 25, a sealing cover 6 capable of rotation is arranged outside the processing groove 13, an electrode target material 18 is arranged inside the processing groove 13, a power supply box 10 for transmitting power to the electrode target material 18 and the circular saw blade 5 is fixedly connected to the outside of the power box 1;

[0031] The electrothermal alloy workpiece 8 to be processed is placed above the two clamping seats 21. The clamping arm 24 is extended by controlling the electric telescopic rod 7, and the workpiece 8 is fixed in place with the pressing block 25. The power box 1 is moved towards the workpiece 8, and one of the circular saw blades 5 is started to rotate. As the circular saw blade 5 approaches the workpiece 8, the part of the workpiece 8 that is exposed above the pressing block 25 can be cut to prepare the raw material of the required thickness. After cutting, the electric telescopic rod 7 near the end of the workpiece 8 is kept fixed, and the other electric telescopic rod 7 is moved away from the first electric telescopic rod. 7. Then, the clamping arm 24 is controlled to fix the workpiece 8. At this time, the electric telescopic rod 7 near the end of the workpiece 8 controls the clamping arm 24 to shorten, releasing the fixation of the workpiece 8. The electric telescopic rod 7 away from the end of the workpiece 8 moves horizontally, thereby extending the end of the workpiece 8 outward by a predetermined length. Then, the end of the workpiece 8 is fixed by the clamping arm 24 again, ready for the next cutting operation. Through the cooperation of the two electric telescopic rods 7, the workpiece 8 can be adjusted to move arbitrarily. The circular saw blade 5 can be made of cemented carbide, and its hardness must be greater than that of the electrothermal alloy. After that, a coating treatment is performed. The coating layer can be divided into three layers.

[0032] From the inside out, the layers are: bottom layer; the bottom layer can use a Ti metal layer, which can improve the affinity, compatibility and wettability between the composite coating and the circular saw blade 5 substrate, help reduce the surface energy at the interface, enhance the bonding force of the composite coating, and at the same time, the bottom layer can also reduce the internal stress between the composite coating and the circular saw blade 5 substrate, and improve the toughness and strength of the composite coating.

[0033] Buffer layer; The buffer layer can be a TiN layer, which can smoothly transition and attenuate the stress inside the composite coating from the inside to the outside. In addition, the presence of the TiN buffer layer improves the compatibility between the bottom layer and the reinforcing layer, and avoids the influence of abrupt changes in composition on the bonding strength between the layers.

[0034] Reinforcing layer; The reinforcing layer can be a single layer of TiCrN or TiAlN; This type of coating has high hardness and significantly improved wear resistance, making it suitable for processing high-hardness materials;

[0055] By setting such a composite layer on the surface of the circular saw blade 5, not only the service life of the circular saw blade 5 is effectively prolonged, but also the polishing effect is increased. However, with the continuous work of the circular saw blade 5, the plated layer on the surface of the circular saw blade 5 will gradually be consumed. By incorporating bright pigments into the buffer layer, when the reinforcing layer is consumed, the exposure of the buffer layer will exhibit the inherent color. At this time, the circular saw blade 5 can be disassembled and replaced, and the consumed reinforcing layer can be supplemented for repeated use, which can ensure the super-long service life of the circular saw blade 5. In order to realize non-stop operation, two circular saw blades 5 can be used. One of the two circular saw blades 5 is used for cutting work first. When the inherent color on the surface of the circular saw blade 5 is exposed, during the next cutting work of the workpiece 8, the sealing cover 6 corresponding to the circular saw blade 5 is controlled to rotate and fold, so that the circular saw blade 5 is sealed in the machining groove 13 and the sealing cover 6.

After switching the circular saw blade 5, the cutting work of the workpiece 8 continues, and after the circular saw blade 5 with the consumed reinforcing layer is in a sealed state, it is first filled with protective gas, which can be argon and nitrogen. Through the power supply box 10, power is input to the electrode target material 18 and the circular saw blade 5. The power supply box 10 provides a high-current, low-voltage power supply for generating an electric arc. The electrode target material 18 forms the negative electrode of the electric arc discharge, and the circular saw blade 5 forms the positive electrode of the electric arc discharge. In the mixed atmosphere of argon and nitrogen, the metal vapor generated by the electric arc discharge reacts with nitrogen to form a TiCrN coating and deposit on the surface of the saw blade. During the coating deposition process, titanium, chromium and nitrogen atoms in TiCrN will form chemical bonds with atoms on the surface of the substrate. Due to the presence of the buffer layer, the atoms in the buffer layer will form stable chemical bonds with the atoms of the substrate and the coating, thereby enhancing the adhesion, thereby forming a reinforcing layer. The thickness of the reinforcing layer is below three microns, which will not affect the cutting. The coating time is basically maintained below two hours, and the coating work can be completed in full.

[0060] After cleaning, drying gas flow can be introduced, and protective gas and reaction gas can also be input into the machining groove 13 through the transmission valve 11, the optical detection module is used for observing the color of the surface of the circular saw blade 5, so as to obtain the wear state, and the air pressure detection module is used for detecting whether air leakage occurs in the machining groove 13.

[0061] By driving the motor 12 to rotate the transmission arm 17, and then drive the sealing cover 6 to rotate upward, until the oblique edge of the sealing cover 6 is attached to the top surface of the power box 1, so as not to affect the normal working process of the circular saw blade 5; it can also be based on the increase of new driving parts, such as the outside of the sealing cover 6 is provided with a winding cable, the power source of the cable is located at the top of the power box 1, providing the power for the stable rotation of the sealing cover 6.

[0062] The cleaning liquid will leak at the bottom, under the action of gravity, fall into the drain groove 15, and finally from the drain valve 9 to the outside, the independent valve is to keep the inside of the processing tank 13 closed.

[0063] Through the connection valve 22 to connect the cooling lubricant, through the nozzle 26 to continuously spray the cooling lubricant to the workpiece 8 and the circular saw blade 5 in the cutting process, to ensure the smooth progress of the processing process.

[0064] The inner recess and the setting of the nozzle 26 can not only avoid the direct contact with the circular saw blade 5, but also can smoothly spray the cooling lubricant to the circular saw blade 5 and the workpiece 8, to ensure the smooth progress of the cutting process.
