[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figure 1 and Figure 2 As shown, in this embodiment, a high-efficiency heat treatment device for improving the hardness of a casting comprises a machine body 1, a door panel 2 is arranged at the feed inlet of the machine body 1, a mounting cover 5 is fixed on the top of the feed inlet of the machine body 1, a material frame 3 is arranged on the top of one end of the machine body 1, rollers 15 are symmetrically and equidistantly installed on the bottom end surface of the material frame 3, a slide rail 4 for the rollers 15 to move is symmetrically fixed on the top surface of one end of the machine body 1, an electric control box 6 is installed in the middle of the surface of one end of the machine body 1, the mounting cover 5 is hollow, and a functional component is arranged at the bottom of the mounting cover 5, and the functional component comprises an air supply pipe 7 arranged at the bottom of the mounting cover 5, one end of the air supply pipe 7 is connected to an external cooling unit, and the bottom end surface edge of the mounting cover 5 is symmetrically fixed. A fixing plate 8 is provided, and a limiting groove 11 for the air supply pipe 7 to engage is provided on the outer surface of the bottom of the fixing plate 8. An air outlet pipe 9 is installed at an equal distance on the bottom of the surface of the air supply pipe 7. A condenser 12 is arranged inside the other end of the air supply pipe 7. A fixing ring 13 for the condenser 12 to engage is fixed at an equal distance on the inner surface of the other end of the air supply pipe 7. A through groove 14 for the end of the condenser 12 to penetrate is symmetrically provided on the surface of the other end of the air supply pipe 7, which is convenient for achieving the purpose of rapid cooling of the casting after heat treatment, so that the surface temperature of the casting can be quickly reduced, which is convenient for workers to take the casting out from the inside of the material frame 3, can improve the work efficiency of workers, improve functionality, and have a better practical effect.

[0021] like Figure 1 As shown, a heat insulation board 10 is installed on the inner surface of the two fixed plates 8. The surface width of the heat insulation board 10 is larger than the outer diameter of the end of the air supply pipe 7, which is convenient for protecting the air supply pipe 7, making it difficult for the internal temperature of the air supply pipe 7 to rise, and the protection effect is better.

[0022] like Figure 3 and Figure 4As shown, a limiting assembly is provided at the edge of the bottom end surface of the material frame 3, and the limiting assembly includes a limiting plate 16 installed on the adjacent edges of both sides of the roller 15. The surface of the slide rail 4 is symmetrically provided with moving grooves 17 for the limiting plate 16 to move. The inner bottom surface of the moving groove 17 is equidistantly provided with fixed grooves 19. The fixed groove 19 is provided with a ball 18 inside. The surface of the ball 18 is rollingly fitted with the bottom end surface of the limiting plate 16. The limiting plate 16 is arranged in an inclined shape.

[0023] The utility model provides a high-efficiency heat treatment device for improving the hardness of castings. The specific working principle is as follows: when the functional components are installed in the early stage of the utility model, the heat insulation board 10 is first pushed to move toward the bottom of the installation cover 5, so that the inner surfaces of the two ends of the heat insulation board 10 are welded and fixed to the surface of the fixing plate 8, and then the air supply pipe 7 is pushed to move toward the surface of the fixing plate 8, so that the air supply pipe 7 can be limitedly engaged to the inside of the limiting card groove 11 on the surface of the fixing plate 8, and then one end of the body 1 is connected to the external cooling unit. At this time, the air outlet pipe 9 needs to be installed on the surface of the air supply pipe 7 at an equal distance, so that the opening of the air outlet pipe 9 faces the inside of the material frame 3, and then the condensation pipe 12 is pushed to move toward the inside of the other end of the air supply pipe 7, so that the condensation pipe 12 can be limitedly engaged to the inside of the other end of the air supply pipe 7 through the fixing clamp ring 13, and then the two ends of the condensation pipe 12 are passed through the inside of the through groove 14 on the surface of the other end of the air supply pipe 7, so that the two ends of the through groove 14 are connected to the external condenser. When the casting is heated After processing, the casting in the material frame 3 will be transported to the outside of the machine body 1. At this time, the wind in the air supply pipe 7 will blow to the surface of the casting through the air outlet pipe 9, so that the temperature of the casting surface can be reduced. At the same time, the condenser 12 can further reduce the temperature inside the air supply pipe 7, so that the wind can be blown to the casting. Rapid cooling can be achieved, which is convenient for workers to subsequently take out the casting from the inside of the material frame 3, which can improve the work efficiency of workers, improve functionality, and have a better practical effect; when the material frame 3 drives the casting to move to the outside of the machine body 1, the material frame 3 will move to the outside of the machine body 1. At this time, the roller 15 will move on the inner side of the slide rail 4, and the limit plate 16 will also move inside the moving groove 17 during the movement of the material frame 3, and the bottom end surface of the limit plate 16 will roll and fit with the surface of the ball 18 inside the fixed groove 19, reducing the friction generated when the limit plate 16 moves, and also makes the material frame 3 not easy to shake left and right during rapid movement, and has better practicality.
