Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, and in particular to a gear heat treatment quenching transfer frame. Background Technology

[0002] Quenching is a process in which castings are heated to above the critical temperature in a furnace, held at that temperature for a certain time, and then cooled in a quenching furnace at a rate greater than the critical cooling rate. When castings enter the furnace, they need to be placed on suitable supports. After holding at that temperature, quenching is performed by transferring batches of castings into the quenching furnace simultaneously using a transfer support. Existing small-volume single-layer supports can only hold a small number of castings. For large-scale production, multiple manual transfers are required. Furthermore, single-layer supports have low space utilization within the furnace, failing to achieve optimal heat utilization. Public technical document CN223061023U – "A Batch Transfer Support for Heat Treatment of Small Castings" – provides a multi-layer transport frame, but it also has significant drawbacks. This is because the support can only be arranged in multiple layers vertically, resulting in differences in heating between the outer and inner layers. Additionally, it is fixed and cannot be flexibly assembled as needed.

[0003] To solve the above problems, a gear heat treatment quenching transfer frame is provided. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a gear heat treatment quenching transfer frame, which effectively solves the problems of the existing heat treatment transfer brackets having a single form, narrow application range, and uneven heating caused by insufficient permeability between inner and outer layers.

[0005] The technical solution includes a central rod, multiple base plates, and multiple arc-shaped plates. The central rod penetrates through the base plates, and multiple horizontal load-bearing rods are provided at the lower end of the central rod. The base plates are disc-shaped, with multiple first arc-shaped grooves on the outer edge of the base plates. The first arc-shaped grooves are concentric with the disc plates, and the base plates have multiple second arc-shaped grooves. One end of the second arc-shaped groove is close to the center of the base plate, and the other end gradually moves away from the center of the base plate. The first arc-shaped grooves and the second arc-shaped grooves are of equal size. Arc-shaped protrusions matching the first arc-shaped grooves and the second arc-shaped grooves are provided at the upper and lower ends of the arc-shaped plates.

[0006] Furthermore, the first arc-shaped groove and the second arc-shaped groove are vertically connected to the bottom plate.

[0007] Furthermore, a hook is provided at the upper end of the central rod.

[0008] This utility model has an ingenious structure that can achieve multiple forms of transformation. It can be designed in multiple layers on the horizontal plane, so that the heating of each layer tends to be consistent. It can also be assembled into a traditional cylindrical frame to achieve heat treatment of ordinary components. In addition, it can also be assembled into a multi-layer structure in the vertical direction. It is flexible and versatile and has a wide range of applications. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0016] Depend on Figures 1 to 6 The present invention comprises a central rod 1, multiple base plates 2, and multiple arc-shaped plates 3. The central rod 1 penetrates through the base plate 2. Multiple horizontal load-bearing rods 4 are provided at the lower end of the central rod 1. The base plate 2 is disc-shaped and has multiple first arc-shaped grooves 5 on its outer edge. The first arc-shaped grooves 5 are concentric with the disc. The base plate 2 has multiple second arc-shaped grooves 6. One end of the second arc-shaped groove 6 is close to the center of the base plate 2, and the other end of the second arc-shaped groove 6 gradually moves away from the center of the base plate 2. The first arc-shaped grooves 5 and the second arc-shaped grooves 6 are of equal size. The upper and lower ends of the arc-shaped plates 3 are provided with arc-shaped protrusions that match the first arc-shaped grooves 5 and the second arc-shaped grooves 6.

[0017] In order to enable vertical multi-layer assembly, the first arc-shaped groove 5 and the second arc-shaped groove 6 are vertically connected to the bottom plate 2.

[0018] In order to enable batch transportation, a hook is provided at the upper end of the central rod 1.

[0019] It is worth noting that the base plate 2, the arc plate 3, and the center rod 1 mentioned above are all made of materials commonly used in heat treatment transfer frames, and the support is a porous mesh structure, which facilitates air permeability. For components such as gears or small shafts, they can be fixed to the side wall of the arc plate 3 using special clamps and fixtures to achieve the greatest possible uniform heating.

[0020] This solution can be assembled into multiple states. The first state is as follows: Figure 1 , 2 As shown, at this time, the arc-shaped plate 3 is inserted into multiple first arc-shaped grooves 5, forming a cylindrical structure that can handle some small, fragmented parts, such as bolts and nuts; the second state, as Figure 3 , 4 As shown, multiple arc-shaped plates 3 are inserted into the second arc-shaped groove 6, forming an impeller-like shape. At this point, special fixtures can be installed on the sidewalls of the arc-shaped plates 3 to hold parts such as small gears and rollers, maximizing uniform and efficient heating of all parts; the third state, as... Figure 5 , 6 As shown, this allows multiple small spaces to be formed, each capable of holding different parts, thus enabling the processing of multiple parts together.

[0021] This utility model has an ingenious structure that can achieve multiple forms of transformation. It can be designed in multiple layers on the horizontal plane, so that the heating of each layer tends to be consistent. It can also be assembled into a traditional cylindrical frame to achieve heat treatment of ordinary components. In addition, it can also be assembled into a multi-layer structure in the vertical direction. It is flexible and versatile and has a wide range of applications.
