[0024] In this embodiment, when in use, the personnel places the tungsten steel milling cutter to be heated in the placement groove 13 of the mounting circular plate 9 and inside the mounting groove 17 of the mounting ring 8, and the personnel starts the motor 5, and the motor 5 drives the adjacent pulleys 15 to rotate. Through the transmission of the belt 16, the two pulleys 15 rotate together, driving the two support rods 6 to rotate. Under the rotation of the pulley 15, one of the support rods 6 drives the infrared heater 11 to rotate through the fixed round seat 12, and the infrared heater 11 will rotate around the tungsten steel milling cutter, and the infrared heater 11 emits infrared radiation to evenly heat the tungsten steel milling cutter. Uniform heating. Through structural design, the infrared heater 11 rotates around the tungsten steel milling cutter, ensuring uniform heating of the tungsten steel milling cutter and avoiding local overheating or insufficient heating. The rotation of the infrared heater 11 can improve the heating efficiency, shorten the heating time, and ensure that the infrared radiation of the infrared heater 11 can evenly cover the surface of the tungsten steel milling cutter, thereby achieving a more uniform heating effect. Uniform heating maintains the structural stability and performance of the tungsten steel milling cutter and ensures the processing quality. It not only saves time and improves heating efficiency, but also reduces energy waste.

[0025] Embodiment 2, as Figure 1 - Figure 4 As shown, one end of the other support rod 6 is fixedly connected to a gear 2 18, and the outer ring of the mounting circular plate 9 is sleeved with a gear 1 7.

[0026] The outer ring of the damper 10 is sleeved with a spring 14 , the top of the spring 14 is fixedly connected to the bottom of the mounting ring 8 , and the bottom of the spring 14 is fixedly connected to the top of the corresponding mounting circular plate 9 .

[0027] The extended end of the support rod 6 is fixedly connected to one side of the adjacent fixed round seat 12 .

[0028] The two pulleys 15 are connected by a belt 16 .

[0029] Gear 1 7 and gear 2 18 are meshed with each other through the latching teeth.

[0030] A motor 5 is fixedly mounted on the bottom of the protective shell 1 , and an output shaft of the motor 5 is drivingly connected to one end of an adjacent pulley 15 .

[0032] In this embodiment, when in use, the two pulleys 15 rotate together, driving the two support rods 6 to rotate. When one of the support rods 6 rotates, it drives gear 2 18 to rotate, and gear 2 18 rotates the transmission gear 1 7 to rotate. Gear 2 18 rotates the transmission gear 1 7 in reverse, and rotates in the opposite direction to the rotation of the infrared heater 11, so that the rotation of the mounting circular plate 9 drives the mounting ring 8 to rotate together. With the rotation of the mounting circular plate 9 and the mounting ring 8, the tungsten steel milling cutter placed in the inner cavity of the placement groove 13 and the mounting groove 17 will also rotate. Through the structural design, the rotation of the tungsten steel milling cutter ensures that its surface can be evenly exposed to the radiation of the infrared heater 11, so that the surface of the tungsten steel milling cutter can evenly receive the infrared heating of the infrared heater 11, and different parts of the tungsten steel milling cutter can be exposed to the radiation of the infrared heater 11 in turn, thereby ensuring that the entire milling cutter surface can evenly receive heat, and the rotation coordination with the infrared heater 11 further improves the heating quality and processing effect of the milling cutter.

[0033] How it works

[0034] When in use, personnel place the tungsten steel milling cutter to be heated in the placement groove 13 of the mounting circular plate 9 and inside the mounting groove 17 of the mounting ring 8, and start the motor 5. The motor 5 drives the adjacent pulleys 15 to rotate. Through the transmission of the belt 16, the two pulleys 15 rotate together, driving the two support rods 6 to rotate. Under the rotation of the pulley 15, one of the support rods 6 drives the infrared heater 11 to rotate through the fixed round seat 12. The infrared heater 11 will rotate around the tungsten steel milling cutter, and the infrared heater 11 will emit infrared radiation to evenly heat the tungsten steel milling cutter. Through the structural design, the infrared heater 11 rotates around the tungsten steel milling cutter, ensuring uniform heating of the tungsten steel milling cutter and avoiding the problem of local overheating or insufficient heating. The rotation of the infrared heater 11 can improve the heating efficiency, shorten the heating time, and ensure that the infrared radiation of the infrared heater 11 can evenly cover the surface of the tungsten steel milling cutter, thereby achieving a more uniform heating effect. The uniform heating maintains the structural stability and performance of the tungsten steel milling cutter and ensures the processing quality. It not only saves time and improves the heating efficiency, but also reduces energy waste. Since the infrared heater 11 usually emits directional radiant heat, when the milling cutter is heated, the surface of the milling cutter cannot be fully exposed to the radiation of the infrared heater 11, and the various parts of its surface cannot be heated in turn, which will lead to the problem that the local part cannot be exposed to the infrared heat source. If the effect of driving the milling cutter to rotate is to be achieved, it is necessary to increase the driving source. The increase in the driving source will increase the energy consumption of the device and cause the cost to rise. The two pulleys 15 rotate together, driving the two support rods 6 to rotate. When one of the support rods 6 rotates, it drives the gear 2 18 to rotate, and the gear 2 18 rotates the transmission gear 1 7 to rotate. The gear 2 18 rotates the transmission gear 1 7 in reverse, which is opposite to the rotation of the infrared heater 11. The mounting plate 9 rotates in the same direction, driving the mounting ring 8 to rotate together. With the rotation of the mounting plate 9 and the mounting ring 8, the tungsten steel milling cutter placed in the inner cavity of the placement groove 13 and the mounting groove 17 will also rotate. Through the structural design, the rotation of the tungsten steel milling cutter ensures that its surface can be evenly exposed to the radiation of the infrared heater 11, so that the surface of the tungsten steel milling cutter can evenly receive the infrared heating of the infrared heater 11, and different parts of the tungsten steel milling cutter can be exposed to the radiation of the infrared heater 11 in turn, thereby ensuring that the entire surface of the milling cutter can evenly receive heat, and the rotation of the infrared heater 11 further improves the heating quality and processing effect of the milling cutter.
