DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figures 1 to 3The utility model provides a technical solution: a metal casting heat treatment mechanism, comprising a heating box 1, a first heating tube 3 fixed to the inner bottom wall of the heating box 1, and a second heating tube 4 fixed to the inner circumferential side wall of the heating box 1. A vertically movable placement basket 2 is arranged inside the heating box 1, and the bottom wall of the placement basket 2 is provided with a circumferentially distributed second strip openings 202, and the circumferential side wall of the placement basket 2 is provided with equidistantly distributed first strip openings 201, and a through opening 101 is opened on the top of the heating box 1, and at least two connecting rods 5 are fixedly connected to the top of the placement basket 2, and a cover plate 6 is fixedly connected to the upper ends of the connecting rods 5, and the cover plate 6 seals the through opening 101 from the top of the heating box 1 to minimize the loss of heat inside the heating box 1 through the through opening 101, thereby improving the heat treatment effect and reducing the heat treatment time.

[0023] The metal casting that needs heat treatment is placed inside the placement basket 2, and then the placement basket 2 is driven down to enter the heating box 1. At this time, the first heating tube 3 and the second heating tube 4 are started to heat treat the metal casting. Since the first strip opening 201 and the second strip opening 202 are arranged on the surface of the placement basket 2, the heat can be fully conducted on the surface of the metal casting.

[0024] In this solution, a cylinder 9 is fixedly installed on the top of the heating box 1, a support plate 8 is fixedly connected to the output end of the cylinder 9, a motor 7 is fixedly installed on the top of the support plate 8, and the output end of the motor 7 is fixedly connected to the cover plate 6.

[0025] By starting the cylinder 9, the support plate 8 is driven to descend, the support plate 8 drives the cover plate 6 to descend, and the cover plate 6 drives the placement basket 2 to descend through the connecting rod 5, so that the placement basket 2 enters the interior of the heating box 1;

[0026] The motor 7 is started to drive the cover plate 6 to rotate, and the cover plate 6 drives the placement basket 2 to rotate through the connecting rod 5, so that the metal casting can be fully and evenly heated to improve the heat treatment effect; and the metal casting is located inside the placement basket 2, Figure 1 It can be seen that, since the placement basket 2 has a circle of circular baffles, it is ensured that the metal casting will not fall off the placement basket 2 during the rotation process, and the first strip-shaped opening 201 is arranged on the baffle of the placement basket 2.

[0027] The through opening 101 is a circular structure, and the diameter of the through opening 101 is larger than the diameter of the placement basket 2 , so as to ensure that the placement basket 2 can smoothly pass through the through opening 101 into the interior of the heating box 1 .

[0028] A plurality of circumferentially distributed transparent windows 10 are embedded on the top of the heating box 1, which facilitate observation of the metal casting inside the heating box 1 and clearly observe the changes and states of the metal casting during the heating process, such as color changes, possible deformation, etc.; the transparent window 10 needs to be made of high-temperature resistant material, such as quartz glass, which has excellent transparency and high-temperature resistance, and can withstand temperature changes inside the high-temperature heating box 1.

[0029] In addition, the transparent window 10 is in a fan-shaped structure, and the fan-shaped design can provide a wider field of view, especially when observing or inspecting the metal castings inside the placement basket 2, the metal castings can be more fully covered.

[0030] The first heating tube 3 has a vortex structure, and the second heating tube 4 has a spiral structure. The vortex and spiral structures can effectively increase the surface area of ​​the heating tubes, thereby enhancing heat transfer with the surrounding medium; this means that heat can be transferred to the metal casting inside the heating box 1 more quickly.
