Embodiment

[0034] As Figures 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the blowing unit 4 includes a rotating rod 41, which is rotatably connected inside the tempering furnace body 1. One end of the rotating rod 41 is fixedly connected to one end of the gear 36. A housing 42 is fixedly connected inside the rotating rod 41. A heat insulation layer 43 is provided inside the housing 42. A second motor 44 is fixedly connected to the inner side of the heat insulation layer 43. A fan blade 45 is fixedly sleeved at the output end of the second motor 44. By controlling the tempering furnace body 1 to work, the second motor 44 is controlled to drive the fan blade 45 to move forward. The rotating rod rotates while simultaneously blowing turbulent air into the heat source generated inside the tempering furnace body 1. At the same time, the outer shell 42 and the heat insulation layer 43 work together to protect the second motor 44. Meanwhile, the first motor 31 drives the first guide rod 32 to rotate. At the same time, the first guide rod 32 drives the rack 34 at one end of the second guide rod 33 to mesh with the gear 36 under the limit of the limiting groove 35. This drives the rotating rod 41 to rotate, and at the same time drives the second motor 44 and the fan blade 45 to swing inside the tempering furnace body 1, so that the hot air inside the tempering furnace body 1 is evenly mixed.

[0035] The working principle of the uniform air blowing device for the tempering furnace will be explained in detail below.

Simultaneously, the heat source generated inside the tempering furnace body 1 is turbulently blown in. The outer shell 42 and the insulation layer 43 work together to protect motor 2 44. Simultaneously, motor 1 31 drives guide rod 1 32 to rotate. Guide rod 1 32 drives the rack 34 at one end of guide rod 2 33 to mesh with gear 36 under the limiting groove 35, which in turn drives rotating rod 41 to rotate. This causes motor 2 44 and fan blade 45 to oscillate inside the tempering furnace body 1, ensuring uniform mixing of hot air inside. The workpiece is then placed inside the tempering furnace body 1. Inside the furnace, the circulating fan 21 is controlled to operate, thereby drawing in hot air from the top surface of the tempering furnace body 1 and delivering it to the inside of the air supply pipe 23. The air is then delivered to the inside of the connecting pipe 24 through the air supply pipe 23, and then blown onto the surface of the workpiece through the blower nozzle 25, thereby rapidly heating the workpiece. At the same time, the combustion-supporting gas can be delivered to the inside of the tempering furnace body 1 through the combustion-supporting gas supply pipe 22 in conjunction with the circulating fan 21 to increase the heating speed. Meanwhile, the T-shaped rod 263 is pulled out from the inside of the fixing hole 262, thereby adjusting the blowing direction of the blower nozzle 25. The T-shaped rod 263 is then placed inside the fixing hole 262, and the connecting pipe 24 is fixed by the elastic action of the spring 264.
