Description

Technical Field

[0001] This utility model relates to the field of casting heat treatment technology, and in particular to a heat treatment device for a small planetary carrier casting. Background Technology

[0002] Planetary carrier products are core components in wind turbine gearboxes, requiring high performance of castings. The material requirement is EN-GJS700-2U, and normalizing heat treatment is generally required. Heat treatment is a key process to ensure its mechanical properties. During the heat treatment process, the planetary carrier castings are often supported and secured by a fixed frame before being placed in a heating device for uniform heating. However, rapid cooling is required after heating. Conventional clamps can easily cause slight deformation of the castings when removing them, and the removal and placement speed is slow. In addition, the castings may be squeezed and deformed at the clamping point due to thermal expansion on the fixed frame. If the clamping is loosened, the castings may easily detach from the fixed frame, resulting in the risk of falling and collision, which affects the integrity of the castings. Utility Model Content

[0003] The purpose of this invention is to provide a heat treatment device for planetary carrier castings, which avoids the problem of extrusion deformation caused by hard contact fixing while also preventing the casting from detaching, ensuring the safety and stability of the casting during transfer and cooling. In addition, after heat treatment, the casting can be directly and quickly transferred for cooling, thereby improving the heat treatment efficiency of the casting.

[0004] To achieve the above objectives, a heat treatment device for asteroid carrier casting is provided, comprising: a base, an electric heating seat fixedly connected to the top center of the base, a heating cavity formed on the top of the electric heating seat, a casting body mounted at the center of the heating cavity, a suspension rod vertically mounted at the center of the inner side of the casting body, a sleeve engaged and fixed to the outer side of the top of the suspension rod, an I-shaped connector fitted and fixed to the top of the sleeve, the I-shaped connector corresponding to and engaging with the boom of a crane, a threaded sleeve threadedly connected to the outer side of the bottom end of the suspension rod, and a ring washer fixedly connected to the bottom end of the threaded sleeve. Several pads are symmetrically fixed on the side cross. Utilizing the hollow structure of the planetary carrier casting, a suspension rod is installed vertically. Through the screw sleeve, ring washer, and symmetrically distributed pads on its outer side, the planetary carrier casting is inserted, limited, and supported. This avoids the squeezing deformation caused by hard contact fixing, while also preventing the casting from detaching. This ensures the safety and stability of the casting during transfer and cooling. In addition, the suspension rod can extend upward to assemble a clamp and I-type joint to cooperate with the boom of a conventional crane. This allows the casting to be directly and quickly transferred for cooling after heat treatment, improving the heat treatment efficiency of the casting.

[0005] According to the aforementioned heat treatment device for asteroid carrier casting, a plurality of heat-insulating feet are symmetrically fixed to the bottom of the base in a cross shape, and the bottom of each heat-insulating foot is fitted with an anti-slip rubber pad to maintain the overall stability of the placement.

[0006] According to the aforementioned heat treatment apparatus for a small planetary carrier casting, a threaded groove is provided at the center of the top of the I-shaped joint. Multiple docking methods are provided for docking with different booms.

[0007] According to the aforementioned heat treatment apparatus for a small planetary carrier casting, several wear-resistant pads are uniformly fixed to the top of the pad plate, and the top ends of the wear-resistant pads are in close contact with the bottom of the casting body. This multi-point positioning and support improves heating uniformity.

[0008] According to the aforementioned heat treatment apparatus for asteroid carrier casting, a plurality of top blocks are fixed in a circular array at the top outer edge of the ring pad. Each top block has a gasket attached to its top, and all gaskets are microporous frosted gaskets. This reduces the contact area while maintaining its anti-slip properties.

[0009] According to the aforementioned heat treatment device for asteroid carrier casting, a sealing cover is fixedly connected to the outer side of the middle portion of the suspension rod. The sealing cover slides downwards and seals against the heating chamber. This reduces heat loss while assisting the suspension rod in positioning and supporting the casting body.

[0010] According to the aforementioned heat treatment apparatus for asteroid carrier casting, a gas valve is fixedly connected to the top front side of the sealing cover to balance the gas pressure within the heating chamber.

[0011] According to the aforementioned heat treatment apparatus for asteroid carrier castings, the suspension rod is made of a high-temperature resistant alloy material. This ensures that the rod remains vertically stable when suspending the casting, thereby ensuring that the casting is positioned at the center of the electric heating chamber for comprehensive and uniform heating.

[0012] The above-mentioned solution has the following beneficial effects: In this invention, the hollow structure of the planetary carrier casting is utilized to install a suspension rod running vertically through the casting. This suspension rod, along with threaded sleeves, ring washers, and symmetrically distributed pads on its outer side, provides insertion, limiting, and support for the planetary carrier casting. This avoids the compression deformation caused by hard contact fixing and prevents the casting from detaching, ensuring safety and stability during the casting transfer and cooling process. Furthermore, the suspension rod can extend upwards to assemble a clamp and I-joint for use with a conventional crane boom. This allows for direct and rapid transfer of the casting for cooling after heat treatment, improving the heat treatment efficiency of the casting.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description
