Description

Technical Field

[0001] This invention relates to the fields of turning and thermal spraying technology, and more specifically, to a tool holder that simultaneously performs turning and thermal spraying. Background Technology

[0002] Thermal spraying, an advanced surface treatment process, heats metal powder or wire to a molten or semi-molten state using a heat source and then sprays it onto the surface of a substrate to form a robust coating. This technology plays a crucial role in various fields such as industry, aerospace, and energy, aiming to repair, protect, and optimize material properties.

[0003] Thermal spraying technology is mostly used on critical components of high-end equipment. This requires machining the components first, followed by thermal spraying. This method is not only inefficient, but the rapid cooling and shrinkage during thermal spraying can also cause tensile stress within the coating. Once this stress exceeds the coating's tolerance limit, cracks will form. Although existing solutions such as substrate preheating and careful selection of spraying materials have achieved some success, they have not completely solved the cracking problem and often increase production costs and time consumption.

[0004] Currently, preheating of the substrate is often required during thermal spraying. However, this not only consumes a lot of energy, but also causes the thermal spray coating to fail to adhere well to the workpiece surface due to oxidation, making it easy to peel off or partially peel off, resulting in coating cracking.

[0005] To address this challenge, there is an urgent need to develop a novel thermal spraying apparatus / method aimed at achieving crack-free and uniform coatings. Therefore, the applicant hereby submits this application after reviewing existing technologies. Summary of the Invention

[0048] Specifically, the bottom center of the inverted conical structure of the main tank 12 is connected to the second end of the tool holder 13 through the flexible tube 8, and the air inlet tube 7 is arranged on the flexible tube 8. Inert gas is input into the air inlet tube 7 to assist the powder to quickly pass through the flexible tube 8 to the spray head 15 of the tool, so as to improve the smoothness of the powder flow during the whole conveying process. In other embodiments, the main tank 12 can be directly pressurized instead of blowing air into the flexible tube 8 through the air inlet tube 7.

[0049] On the basis of the above-mentioned embodiments, one of the alternative embodiments of the present application is shown in Figure 1 and Figure 2 The powder feeding assembly comprises at least two powder feeding barrels 2. The at least two powder feeding barrels 2 are connected to the upper part of the main tank 12.

[0050] Specifically, the powder feeding barrel 2 is filled with powder for cladding.

The discharge pipe 103 is a rigid pipe made of steel or other metal materials, which can support the powder feeding barrel 2 and does not need to additionally provide a support frame for the powder feeding barrel 2. The powder feeding barrel 2 is also provided with a barrel cover, which can be opened to add powder to the powder feeding barrel 2, and a switch valve on the discharge pipe 103 is used to control the discharge amount of the powder.

[0051] In the embodiment, the top of the main box body 12 is provided with two powder feeding barrels 2, which are placed at the center symmetric positions of the main box body 12.

[0052] In an alternative embodiment, as shown in Figure 2 The upper end of the powder conveying pipeline 3 is configured as a funnel structure, and the circular tube portion is connected to the upper end. Preferably, the lower end of the powder conveying pipeline 3 is configured as a disc structure to be connected to the inner wall of the main box body 12.

[0053] Specifically, the upper end of the powder conveying pipeline 3 is in an inverted conical structure, and the powder discharged from the powder feeding barrel 2 into the main box body 12 can be concentrated in the middle structure of the powder conveying pipeline 3, thereby improving the utilization rate of the powder.

[0054] Based on the above embodiment, in an alternative embodiment of the present application, as shown in Figure 1 and Figure 2 The synchronous turning and thermal spraying further comprises a stirring assembly connected to the powder feeding assembly. The stirring assembly comprises a rotatable stirring shaft 11 and a stirring motor 1 connected to the stirring shaft 11. The stirring shaft 11 extends into the circular tube portion, and at least a portion of the stirring shaft 11 extending into the circular tube portion is fixed with a plurality of stirring blades 4. The stirring blades 4 are in a spiral structure. At least two of the powder feeding barrels 2 are symmetrically arranged with respect to the center of the stirring shaft 11.

[0055] Specifically, the stirring assembly comprises a stirring motor 1 placed on the upper surface of the top wall of the main box body 12, the stirring motor 1 is connected to the top end of the stirring shaft 11, the bottom of the stirring shaft 11 extends into the middle end of the powder conveying pipeline 3, and a plurality of stirring blades 4 are fixed to the stirring shaft 11 extending into the middle end of the powder conveying pipeline 3.

[0056] The stirring motor 1 can drive the stirring shaft 11 to rotate around its own axis, and the stirring blades 4 are used to stir the powders in the circular tube part, so that different powders can be stirred and mixed uniformly in the circular tube part. The stirring and heating are carried out at the same time, which can ensure the dryness of the powders and prevent the powders from being accumulated, and the powders can be smoothly dropped into the vibrating screen 6 at the bottom of the main box body 12 through the stirring.

[0057] It should be noted that the stirring and heating of the powders are carried out at the same time, which can prevent the powders from being accumulated while dehumidifying the powders. The powders are transported to the powder spraying device together with the inert gas of the air inlet pipe 7, and then the scale knob 18 is rotated to control the angle of the spray head 15, so that the thermal spraying on the machined surface of the workpiece 102 in the hard turning process is realized. Through this synchronous thermal spraying mode, the alloy powders are cladded on the surface of the substrate by using cutting heat, the substrate can be preheated, the temperature difference between the substrate and the powders is reduced, the generation of coating cracks is inhibited, the surface activity is improved, the bonding force with the coating is increased, the newly generated cutting surface has no oxide layer, the crack sensitivity of the coating is reduced, and the workpiece 102 does not need to be stopped and disassembled in this process, so that the modification of the surface of the workpiece 102 is realized efficiently.

[0058] On the basis of the above embodiment, an alternative embodiment of the present application is shown in Figure 2 The powder supply assembly further includes a vibrating screen 6 engaged with the inside of the main box body 12, and a vibrating motor 9 engaged with the vibrating screen 6.

[0059] Specifically, the vibrating screen 6 is connected with a screen support, and the screen support is fixed to the inner wall of the main box body 12. The vibrating motor 9 generates vibration to screen the powders, so that the powders meeting the particle size requirements can pass through the vibrating screen 6, and the powders that are accumulated or have a particle size that is too large are left on the vibrating screen 6. The powders meeting the requirements can enter the flexible pipe 8 through the inverted conical structure at the bottom of the main box body 12. The flexible pipe 8 is made of flexible materials, such as rubber pipes and corrugated pipes, to adapt to the movement of the tool.

[0060] On the basis of the above embodiment, an alternative embodiment of the present application is shown in Figure 2 The heater 10 includes an electric heating pipe 5 sleeved on the powder conveying pipeline 3.

[0061] Specifically, the electric heating pipe 5 is installed on the outer wall of the middle part of the powder conveying pipe 3. The electric heating pipe 5 outputs energy through the heater 10, and the set temperature is 95-120 DEG C. At the same time, in order to prevent the heat generated by the electric heater 10 from being transmitted to the wall of the main box 12 and causing a threat to the safety of the staff, heat insulation material is arranged between the main box 12 and the electric heating pipe 5, or the inner side wall or the outer side wall of the main box (12) is coated with heat insulation material.

[0062] It should be noted that the thermal sprayed powder is some common coating wear-resistant nano-alloy powder, such as nickel-based nano-alloy powder with a melting point of about 850-1000 DEG C, cobalt-based nano-alloy powder with a melting point of about 900-1000 DEG C, aluminum-based nano-alloy powder with a melting point of about 800-950 DEG C, and zinc-based nano-alloy powder with a melting point of about 800-1000 DEG C.

[0063] The turning tool generates a large amount of heat during the hard turning process of the workpiece 102, and the cutting temperature can exceed 1000 DEG C. This not only enables common wear-resistant nano-alloy powder, such as nickel-based nano-alloy powder with a melting point of 850-1000 DEG C, cobalt-based nano-alloy powder with a melting point of 900-1000 DEG C, aluminum-based nano-alloy powder with a melting point of 800-950 DEG C, and zinc-based nano-alloy powder with a melting point of 800-1000 DEG C, to be fused on the surface of the base material, but also effectively preheats the base material and reduces the temperature difference between the coating and the base material.

[0064] The turning and spraying synchronous forming tool bar of the embodiment of the present application melts the powder by using the cutting temperature. At the same time, the heat generated during the turning process can also preheat the base material, reduce the temperature difference between the base material and the powder, and inhibit the generation of coating cracks. The cutting heat can also increase the surface activity and increase the bonding force with the coating, and the newly generated cutting surface has no oxide layer, which reduces the crack sensitivity of the coating. Moreover, the workpiece 102 does not need to be stopped and disassembled during the process, so that the modification of the surface of the workpiece 102 is efficiently realized, the work efficiency is greatly improved, and the automation production and industrial innovation and upgrading are promoted.
