Description

Technical Field

[0001] The utility model relates to a heat treatment tooling, in particular to a heat treatment tooling for assisting in loading rolling elements. Background Art

[0002] For the heat treatment of rolling elements, the current operation method is to stand the rolling elements vertically in a wire mesh frame. During the movement of the tooling, the products will shake and fit together, affecting the heat treatment quality. Even worse, they may fall over and roll inside the tooling, causing knocking and bruising. To solve the above problems, the existing solution is to separate the rolling elements with thin iron rods. The existing solution has the following problems:

[0003] 1), The operation is cumbersome. It is necessary to control the number of rolling elements separated by the thin iron rods. If the number of rolling elements is small, there will be too much gap between the thin iron rods. During the subsequent movement of the tooling, the products may still fall over, and it is necessary to fill the gaps separately. Attention also needs to be paid to the spacing between the rolling elements.

[0004] Secondly, the disassembly and assembly of the thin iron rods require additional operations to fix them on the wire mesh frame, such as wire bundling, welding or snap fixation.

[0005] 2), The thin iron rods are deformed greatly. The thin iron rods have a certain length, and there is no additional fixation and support in the middle part of the thin iron rods. During the subsequent movement of the tooling, the shaking and extrusion of the rolling elements will cause the thin iron rods to deform, especially in the middle section of the thin iron rods. At the same time, the more the number of rolling elements, the greater the deformation of the thin iron rods.

[0006] 3), The thin iron rods are not durable. Due to the large deformation problem of the thin iron rods, frequent deformation will cause metal fatigue and fracture, or the thin iron rods will remain deformed after participating in the heat treatment and cannot be restored. Summary of the Utility Model

[0007] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, to provide a heat treatment tooling for assisting in loading rolling elements.

[0008] The technical solution adopted by the utility model to solve its technical problem is: a heat treatment tooling for assisting in loading rolling elements, including a wire mesh frame, and further including a plurality of gratings arranged in cooperation with the wire mesh frame. Rolling elements are arranged between adjacent two gratings.

[0009] A number of small holes are equidistantly spaced on the grating. Grooves are provided on the frames of the grating at the upper and lower ends of each small hole. The grooves between adjacent two gratings cooperate with each other to form a limiting structure for limiting the rolling elements.

[0010] Further, the grating is strip-shaped, and the small holes opened on the grating are rectangular small holes.

[0011] Further, the rolling elements are cylindrical and are vertically standing in the limiting structure between the two gratings.

[0012] Further, both sides of the grating are provided with hooks which are cooperatively arranged with the frame of the mesh frame.

[0013] The beneficial effects of the present utility model are as follows: The heat treatment tooling for assisting in loading rolling elements of the present utility model has the characteristics of simple operation, small deformation and durability. Specifically:

[0014] Simple operation: By limiting each rolling element through the limiting structure, the problems of the products sticking to each other, shaking and toppling are solved. The limiting structure ensures that the distance between two adjacent rolling elements is equal, improving the quality and consistency of the rolling elements in the same batch. At the same time, the loading is neat, the rolling elements are stably fixed and will not displace; Secondly, there are hooks on both sides of the grating, and the grating can be quickly disassembled and assembled by clamping the hooks on the frame of the mesh frame.

[0015] Small deformation and durability: There are small holes equidistantly spaced on the grating. Compared with the thin iron rod changing from a strip structure to a frame structure, the anti-deformation ability is improved. Secondly, the limiting structure ensures that there will be no situation where the rolling elements squeeze each other, solving the deformation of the thin iron rod caused by the mutual extrusion of the rolling elements, thereby improving the durability of the grating.

Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model.

[0024] Figures 1 to 5 A heat treatment tooling for assisting in loading rolling elements is shown, including a frame 1 and a grille 2. The number of grilles 2 is multiple, and a number of small holes 3 are equidistantly spaced on each grille 2. To improve the anti-deformation ability of the grille 2, the small holes 3 are usually processed into rectangles. Grooves 4 are provided on the frame edges of the grille 2 at both the upper and lower ends of each small hole 3. The grooves 4 between two adjacent grilles 2 cooperate with each other to form a limiting structure for limiting the rolling element 5. The rolling element 5 is cylindrical and is vertically placed in the limiting structure between the two grilles 2. To facilitate the installation of the grille 2 and the frame 1, hooks 6 are provided on both sides of the grille 2, and the hooks 6 are arranged in cooperation with the frame edges of the frame 1.

[0025] The small holes 3 are processed into rectangles. The grille 2 can be regarded as a frame structure composed of multiple rectangles connected together. The frame structure has a higher anti-deformation ability compared to general strip-shaped bodies. The grooves 4 can be regarded as clamping parts. The two C-shaped grooves 4 on both sides form a limiting structure that clamps the outside of the rolling element 5. The limiting structure and the rolling element 5 are in line contact and will not affect the quality of the rolling element 5.

[0026] According to the heat treatment requirements, two adjacent rolling elements 5 can be placed with multiple limiting structures spaced as shown in the figure, or one rolling element 5 can be placed in each limiting structure.

[0027] During actual use

[0028] The first layer of grille is clamped to one side of the frame edge of the frame 1 through the hook 6. The rolling elements 5 are arranged in the grooves 4 as required. The second layer of grille and the first layer of grille are installed and loaded in the same operation. Repeat this process until the last layer of grille is installed in place. The adjacent two layers of grilles firmly limit the rolling elements 5 in the limiting structure. During the movement of the entire tooling, the rolling elements 5 always remain vertically standing at equal intervals in the frame 1.

[0029] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
