Description

Technical Field

[0001] This utility model belongs to the field of sleeve processing technology, specifically relating to an annealing device for hexagonal sleeve processing. Background Technology

[0002] The hexagonal socket in a hexagonal wrench has a regular hexagonal interior and a generally circular exterior. Depending on the manufacturing process, the exterior of the hexagonal socket may require drilling, grooving, or other machining. After machining, the socket may retain residual stress, necessitating annealing. Although hexagonal sockets are small, they come in various sizes. While annealing a large number of hexagonal sockets simultaneously in an existing annealing furnace can increase efficiency, the overall weight of a large number of sockets makes loading and unloading them inconvenient and easily leads to confusion between different sizes.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0013] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] like Figure 1-2As shown, the hexagonal sleeve processing annealing device includes an annealing furnace 1. The annealing furnace 1 has an opening on one side, covered by a furnace cover 2. A slide rail 3 is installed inside the annealing furnace 1, with one end pointing towards and close to the furnace cover 2. Several trolleys 4 are sequentially connected on the slide rail 3, and each trolley 4 holds several workpiece boxes 5 stacked sequentially from bottom to top. Each workpiece box 5 includes a perforated base plate 6, on which the hexagonal sleeves are placed. The hexagonal sleeves to be annealed are placed in the workpiece boxes 5, and multiple workpiece boxes 5 are stacked and placed on the trolleys 4. The trolleys 4 are pushed into the furnace sequentially, connecting adjacent trolleys 4. After annealing, the workpiece boxes 5 on the trolley 4 closest to the furnace opening are removed one by one, and then the empty trolley 4 is pulled out, causing the subsequent trolleys 4 to approach the furnace opening for unloading.

[0016] Furthermore, each end of the trolley 4 is provided with a horizontal tube 7, and two adjacent trolleys 4 are connected by two U-shaped rods 8, with both ends of the U-shaped rods 8 inserted into the horizontal tubes 7. The two sides of adjacent trolleys 4 can be quickly connected or disassembled through the U-shaped rods 8, which facilitates the movement of the trolleys 4 in the annealing furnace 1 and makes it easy for the trolleys 4 to enter and exit the annealing furnace 1.

[0017] Furthermore, the trolley 4 is provided with insertion tubes 9 at its four corners, and the workpiece box 5 is fixed with support columns 10 at its four lower corners. The workpiece box 5 is provided with slots 11 at its four upper corners. The support columns 10 at the four lower corners of the workpiece box 5 are inserted into the insertion tubes 9 or slots 11 respectively. The cooperation of the support columns 10, insertion tubes 9, and slots 11 ensures that the workpiece box 5 remains stable on the trolley 4, preventing it from slipping during trolley movement and ensuring production safety.

[0018] Furthermore, the height of the support column 10 is greater than the depth of the insertion tube 9 and the depth of the slot 11. This ensures sufficient spacing between the upper and lower workpiece boxes 5, allowing for uniform heating of the workpiece boxes 5 and guaranteeing that all hexagonal sleeves can be annealed according to the set annealing process.

[0019] Furthermore, the annealing furnace 1 includes an outer furnace body 12 and an inner furnace body 13. The inner furnace body 13 is located inside the outer furnace body 12, and an insulation layer 14 is provided on the outer side of the inner furnace body 13. The furnace cover 2 is hinged to the outer furnace body 12, and an inner cover 15 is installed on the inner furnace body 13. The slide rail 3 is located in the inner furnace body 13. This multi-layer furnace structure provides better insulation and more stable furnace temperature.

[0020] Furthermore, a limiting plate 16 is provided at the end of the slide rail 3 away from the furnace cover 2. The limiting plate 16 restricts the position of the trolley 4 to prevent the trolley 4 from damaging the annealing furnace 1 during movement.

[0021] It is worth mentioning that the technical features such as the annealing furnace involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0022] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
