Abstract
Description
Technical Field
[0001] This application relates to the field of materials processing equipment technology, and in particular to a laser cladding device with a circulating cooling mechanism. Background Technology
[0002] In modern manufacturing, laser cladding technology, as an important surface modification and repair technique, is widely used in many fields such as aerospace, machinery manufacturing, and the automotive industry. Laser cladding uses a high-energy-density laser beam to fuse alloy powders or other coating materials with specific properties onto the surface of a substrate, thereby obtaining a cladding layer with excellent wear resistance, corrosion resistance, and high-temperature resistance.
[0003] A search revealed Chinese Patent Publication No. CN209537627U, which discloses a laser cladding device with a circulating cooling mechanism. The device includes a machine tool and a transverse moving axis. The transverse moving axis is positioned above the machine tool, with a storage bin on its upper side. A laser beam lamp is mounted on the transverse moving axis, and a feeding pipe is located on one side of the laser beam lamp. A speed regulator is located on the upper side of the feeding pipe, and a water cooling mechanism is located on one side of the feeding pipe. A longitudinal moving axis is located within the water cooling mechanism, and a temperature sensor is located within the longitudinal moving axis. A cooling plate is located below the longitudinal moving axis, and a circulating water pipe is mounted on the cooling plate.
[0004] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: The coolant circulation path design of the aforementioned devices is simple, relying solely on cooling plates and circulating water pipes. The coolant flow lacks an effective guidance and acceleration mechanism, making it difficult to fully utilize the coolant's heat dissipation potential, resulting in low cooling efficiency. Simultaneously, the heat dissipation structure is relatively simple, failing to effectively conduct and dissipate the high heat generated by the laser cladding gun head. It cannot promptly transfer heat from critical components, easily causing heat accumulation, affecting the stable operation and lifespan of the device, and failing to meet the stringent requirements of high-efficiency heat dissipation for laser cladding.

[0029] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0030] This application discloses a laser cladding device with a circulating cooling mechanism.
[0031] Please see Figure 1 A laser cladding device with a circulating cooling mechanism includes a cooling chamber shell 1, a cooling component 2 is disposed inside the cooling chamber shell 1, and a laser cladding gun head 3 is disposed on one side of the cooling component 2;
[0032] Please see Figures 2 to 6 Cooling assembly 2 includes a sealing top cover 201, an inlet pipe 202, an outlet pipe 203, a drain chamber housing 204, turbine blades 205, a turbine ring 206, a turntable 207, a heat sink 208, and heat sink fins 209. The sealing top cover 201 is fixedly installed on the top of the cooling chamber housing 1. The inlet pipe 202 is fixedly connected to the top of the sealing top cover 201, and a one-way valve is fixedly installed inside the inlet pipe 202. The sealing top cover 201 is located away from the inlet pipe 202. A liquid outlet pipe 203 is fixedly connected to one side of the sealing top cover 201. A drain chamber shell 204 is fixedly connected to the bottom of the sealing top cover 201. A turbine ring 206 is movably installed at the bottom of the drain chamber shell 204. Turbine blades 205 are fixedly connected to one side of the turbine ring 206. A turntable 207 is fixedly installed at the bottom of the turbine ring 206 by bolts. A heat sink 208 is fixedly connected to the bottom of the turbine ring 206. Heat sink fins 209 are fixedly connected to one side of the heat sink 208.
[0033] The cooling assembly 2 also includes a heat pipe positioning ring 210, a sealing base plate 211, and a heat-conducting plate 212. The heat pipe positioning ring 210 is fixedly installed at the bottom of the heat dissipation cylinder 208 by bolts. A heat-conducting plate 212 is fixedly connected to one side of the heat pipe positioning ring 210. The heat-conducting plate 212 is movably connected to one side of the laser cladding gun head 3. A sealing base plate 211 is provided at the bottom of the heat-conducting plate 212. The sealing base plate 211 is fixedly installed on one side of the laser cladding gun head 3. The sealing base plate 211, the cooling chamber shell 1, and the sealing top cover 201 together form a sealed cavity.
[0034] The one-way valve inside the inlet pipe 202 only allows coolant to enter the sealed cavity formed by the sealing base plate 211, the cooling chamber shell 1, and the sealing top cover 201, while the one-way valve inside the outlet pipe 203 only allows coolant to exit the sealed cavity.
[0035] The turbine ring 206 and turbine blade 205 rotate around the laser cladding gun head 3, and the movement trajectory of the turbine blade 205 is located directly below the liquid inlet pipe 202.
[0036] The heat-conducting plate 212 includes an arc-shaped heat-conducting plate attached to one side of the laser cladding gun head 3 and a heat pipe fixedly connected between the arc-shaped heat-conducting plate and the heat sink 208, and the heat pipe is fixedly connected to the heat sink 209.
[0037] The turbine ring 206, the drain chamber housing 204, and the sealing top cover 201 together constitute the coolant drain chamber, and the coolant drain chamber is connected to the outlet pipe 203.
[0038] Further explanation is needed: Cooling component 2 plays a crucial role in the entire laser cladding device. Coolant is injected through the inlet pipe 202, directly impacting the turbine blades 205. The turbine blades 205, under pressure, drive the turbine ring 206 to rotate. The turbine ring 206 is tightly connected to the heat sink 208 and heat sink 209. Therefore, as the turbine ring 206 rotates, the heat sink 208 and heat sink 209 also rotate. This ingenious design utilizes the kinetic energy of the coolant to drive the turbine rotation, thereby achieving rotational cooling of the heat sink 208 and heat sink 209. Compared to traditional static cooling methods, rotational cooling significantly increases the heat dissipation area and airflow, effectively improving heat dissipation efficiency and ensuring the entire cooling system can quickly and effectively dissipate heat. The heat pipe positioning ring 210 effectively dissipates heat, providing a good heat dissipation guarantee for the stable operation of the laser cladding device. The heat pipe positioning ring 210 firmly fixes the heat-conducting plate 212. One end of the heat-conducting plate 212 is tightly attached to the laser cladding gun head 3, and the other end is connected to the heat sink 208 and heat sink 209 through the heat pipe. When the laser cladding gun head 3 generates a lot of heat during operation, the heat can be quickly conducted through the heat-conducting plate 212 to the heat pipe, and then transferred by the heat pipe to the heat sink 208 and heat sink 209. In this way, the heat-conducting plate 212 acts as a bridge for heat transfer, effectively dissipating the heat generated by the laser cladding gun head 3, keeping the gun head at a suitable working temperature, avoiding performance degradation or failure due to overheating, and effectively ensuring the stable operation of the laser cladding device.
[0039] The implementation principle of a laser cladding device with a circulating cooling mechanism in this application embodiment is as follows:
[0040] First, coolant is injected into the entire cooling system through inlet pipe 202. The one-way valve installed inside inlet pipe 202 ensures that the coolant can only flow in one direction and smoothly enter the sealed cavity formed by the sealing base plate 211, the cooling chamber shell 1, and the sealing top cover 201.
[0041] Secondly, the injected coolant directly impacts the turbine blades 205. Since the turbine blades 205 are fixedly connected to the turbine ring 206, under the impact force of the coolant, the turbine blades 205 drive the turbine ring 206 to start rotating. Because the turbine ring 206 is tightly connected to the heat sink 208 and the heat sink 209, the heat sink 208 and the heat sink 209 also rotate together.
[0042] Next, when the laser cladding gun head 3 starts working and generates a lot of heat, the heat-conducting plate 212 attached to one side of the gun head begins to play its role. One end of the heat-conducting plate 212 is tightly attached to the gun head and can quickly absorb the heat generated by the gun head. The other end is connected to the heat sink 208 and the heat sink 209 through the heat pipe, and conducts the absorbed heat to the heat pipe.
[0043] Next, the heat pipe will transfer the heat obtained from the heat-conducting plate 212 to the heat sink 208 and the heat sink 209. The rotating heat sink 208 and the heat sink 209 greatly increase the contact area with the air, promote air flow, and quickly dissipate the heat to the surrounding environment to achieve efficient heat dissipation.
[0044] Finally, after the coolant impacts the turbine blades 205, it enters the coolant discharge chamber, which is composed of the turbine ring 206, the drain chamber shell 204, and the sealing top cover 201. Then it is discharged through the outlet pipe 203. The one-way valve inside the outlet pipe 203 ensures that the coolant can only flow out, realizing the circulation of the coolant and continuously providing heat dissipation power for the entire cooling system, maintaining the stable operation of the laser cladding device.
[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
