[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a precision casting uniform heat treatment device, including a box 1, which is made of heat-insulating material to provide a closed space environment for the heat treatment process, protecting the internal components from external interference. A box door 2 is provided on the front side of the box 1 for easy opening or closing by the operator. It is mainly used to put the casting into the box 1 or take out the heat-treated casting from the box 1. Heating tubes 8 are provided on the inner wall of the box 1, which convert electrical energy into heat energy to provide the heat required for the heat treatment process. Cavities are opened on the left, right and upper inner walls of the box 1. Multiple sets of heating tubes 8 are provided, which are respectively arranged on the inner wall of the cavity. The reasonable distribution of multiple sets of heating tubes 8 in the cavity ensures that the box 1 can obtain sufficient and uniform heat supply in a short time, meeting the temperature requirements of precision casting heat treatment. This technology is prior art, so it will not be described in detail.
[0031] Furthermore, the inner wall of the housing 1 is provided with a heat outlet groove 3, which provides a specific outlet channel for the heat generated by the heating tube 8. The inner wall of the housing 1 is provided with a swing assembly, which includes a connecting assembly and a driving assembly. The connecting assembly includes a swing frame 41, which can swing at a certain angle to change the direction of the heat flow, initially dispersing the originally concentrated heat flow and causing the heat to begin to diffuse in different directions. The swing frame 41 is rotatably connected to the inner wall of the heat outlet groove 3. A connecting rod 42 is fixedly connected to the top of the swing frame 41, which cooperates with the moving plate 5. When the moving plate 5 moves, it drives the connecting rod 42 to slide on the inner wall of the guide groove 45, thereby driving the swing frame 41 to rotate. The upper inner wall of the housing 1 is rotatably connected with a swing frame 43, which changes the direction of the heat flow generated by the heating tube 8 on the upper side. A connecting rod 44 is fixedly connected to the outer side of the swing frame 43, which cooperates with the limiting groove 46, and can drive the swing frame 43 to swing back and forth. The upper inner wall of the housing 1 is slidably connected with the moving plate 5.
[0032] Reference Figure 2 and Figure 3 The movable plate 5 is U-shaped and can simultaneously drive multiple sets of swing frames 41 and 43. A guide groove 45 is provided through the outer side of the movable plate 5, which provides a precise path for the sliding of the connecting rod 42. The connecting rod 42 slides on the inner wall of the guide groove 45. A limit groove 46 is provided on the upper side of the movable plate 5, which restricts and guides the connecting rod 44, ensuring that the swing frame 43 rotates on the predetermined trajectory. The connecting rod 44 slides on the inner wall of the limit groove 46.
[0033] Reference Figure 2 and Figure 3 A bracket 6 is fixedly connected to the rear top of the housing 1, providing a stable mounting position for the drive motor 61. The drive assembly includes the drive motor 61, which serves as the power source for the entire swing assembly. It drives the turntable 62 to rotate through the output shaft, providing continuous and stable power for the swing of the swing frame 41 and the swing frame 43. The turntable 62 is fixedly connected to the lower side of the output shaft of the drive motor 61. The rotation of the turntable 62 converts the circular motion of the motor into the reciprocating motion of the slide rod 64, thereby driving the moving plate 5 to move. The slide rod 64 is fixedly connected to the lower side of the turntable 62 off-center. A slide groove 63 is opened on the rear side of the moving plate 5. The slide rod 64 slides on the inner wall of the slide groove 63, converting the rotation of the turntable 62 into the horizontal reciprocating motion of the moving plate 5. The heat outlet grooves 3 are respectively opened on the upper inner wall and the left and right inner walls of the housing 1. Multiple sets of swing frames 41 and connecting rods 42 are provided, and the multiple sets of swing frames 41 and connecting rods 42 are symmetrically arranged with the center line of the housing 1 as the axis of symmetry.
[0034] Reference Figure 1 and Figure 4The inner wall of the housing 1 is provided with a support assembly, which includes a placement plate 71 for placing the precision casting to be heat-treated. The placement plate 71 is hollow, which can reduce its own weight and at the same time ensure the smooth flow of heat in the lower space of the housing 1, so that all surfaces of the casting can be fully heated. The number of placement plates 71 can be easily added or adjusted according to the number and specifications of the casting, which improves the adaptability of the device to different production needs. The placement plate 71 slides on the lower inner wall of the housing 1. There are multiple sets of placement plates 71, and a connecting column 72 is inserted between two sets of placement plates 71. There are multiple sets of connecting columns 72 to enhance the stability between the placement plates 71.
[0035] Working principle: When in use, start the drive motor 61, and its output shaft drives the turntable 62 to rotate. Since the slide rod 64 is fixedly connected to the lower side of the turntable 62 off-center, the rotational motion of the turntable 62 is converted into the horizontal reciprocating motion of the moving plate 5 on the inner wall of the slide groove 63 on the rear side of the moving plate 5.
[0036] When the moving plate 5 moves, the connecting rod 42 fixed at the top of the multiple sets of swing frames 41 slides on the inner wall of the guide groove 45, causing the swing frame 41 to rotate on the inner wall of the heat outlet groove 3, thereby changing the direction of the heat flow from the heat outlet groove 3, initially dispersing the relatively concentrated heat flow, and causing the heat to diffuse in different directions.
[0037] Meanwhile, the connecting rod 44 fixed on the outside of the swing frame 43 slides on the inner wall of the limiting groove 46, causing the swing frame 43 to swing back and forth, changing the direction of the heat flow generated by the upper heating pipe 8. In this way, the coordinated movement of the swing frame 41 and the swing frame 43 achieves the uniform distribution of heat in all parts of the box 1, ensuring that the heat is evenly distributed in the entire space of the box 1.
[0038] Depending on the quantity and specifications of the castings to be processed, the number of placement plates 71 can be easily added or adjusted through multiple sets of movable connecting columns 72, ensuring that the castings are in a stable position during the heat treatment process and that each casting can complete the heat treatment in a uniform heat environment.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
