Description

Technical Field

[0001] The utility model relates to the technical field of material hanging tooling structures, in particular to a material hanging tooling used for products with a center hole. Background Art

[0002] For products with a center hole in the heat treatment process, the existing hanging method is to hang the material through the center hole of the product with a 40mm wide hanging rod. The hanging rod is welded and smooth. After the product is loaded, it will shake during the transfer process and slide together and overlap, causing increased deformation and instability during the heat treatment process. Secondly, the overlap of products leads to a decrease in the fluidity and cooling capacity of the heat treatment atmosphere, resulting in large dispersion of metallurgical indicators or even failure.

[0005] The partition includes raised portions at the same heights at the front and rear ends of the tooling plate; the front and rear ends of the groove are provided with chamfered portions matching the center hole of the product to be hung, and when the product to be hung is hung in the groove, the left and right contact force-bearing surfaces in the center hole thereof fit with the chamfered portions;

[0006] By adopting the above technical solution, the groove group structure evenly divides the distance between each product, and the products will not slide together and overlap during movement, thereby ensuring the product spacing; ensuring the circulation of atmosphere during heat treatment and the uniformity of quenching cooling; the chamfered surface can be specifically contoured according to the contact surface shape of the product center hole to achieve a good fit when the product is hung, increase the contact width and force area, reduce the degree of product deformation, and improve the qualified rate.

[0007] Furthermore, the retaining groove group structure of the utility model is symmetrically arranged on the front and back sides of the tooling plate;

[0008] By adopting the above technical solution, both the front and back sides can be used, and the spare side can achieve self-shaping to increase the service life.

[0009] Furthermore, one end of the tooling plate of the utility model is provided with a snap-on structure, and the other end is a plug-in portion, which facilitates the overlapping installation of the tooling and the equipment;

[0010] Furthermore, the tooling plate described in the utility model is also provided with process holes, which reduces weight and is more beautiful.

[0011] The beneficial effects of the utility model are as follows: the defects existing in the background technology are solved, uniform barriers are made in the hanging rod, the spacing between each product is evenly divided, the products will not slide together and overlap during the movement, and the product spacing is guaranteed; the circulation of the atmosphere during heat treatment and the uniformity of quenching and cooling are guaranteed, and the dispersion of metallurgical indicators is reduced; the width of the center hole hanging rod is increased, and the contact position between the tooling and the product is made into a copy shape, thereby increasing the contact width of the product, increasing the force-bearing area, and reducing deformation.

[0017] Process hole DETAILED DESCRIPTION

[0018] Now the utility model is further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] like Figure 1 to Figure 4 The tooling for hanging products with center holes shown in the figure comprises a long strip tooling plate 1, on which at least one section of a groove group structure is arranged, and the groove group structure comprises spacers 2 and grooves 3 arranged alternately in the transverse direction; the spacers 2 comprise raised portions arranged at the same height at the front and rear ends of the tooling plate 1; the front and rear ends of the grooves 3 are provided with chamfered portions 6 matching the center hole 5 of the product 4 to be hung, and when the product 4 to be hung is hung in the groove 3, the left and right contact force-bearing surfaces in the center hole 5 thereof are in contact with the chamfered portions 6;

[0020] The retaining groove group structure is symmetrically arranged on the front and back sides of the tooling plate 1; both sides can be used, and the spare side can achieve self-shaping to increase the service life.

[0021] One end of the tooling plate 1 is provided with a snap-fit ​​structure 7, and the other end is a plug-in portion 8, which facilitates the overlapping installation of the tooling and the equipment; the tooling plate 1 is also provided with a process hole 9, which reduces weight and is more beautiful.

[0022] Working principle:

[0023] Hang several products to be heat treated with center holes in the grooves on the tooling plate. The products are blocked by partitions, and the product spacing is uniform to prevent sliding, thereby ensuring the circulation of the heat treatment atmosphere and the uniformity of cooling. The contact force surfaces at the left and right ends of the center hole of the product fit with the chamfered surface in the groove, which has a larger contact area than traditional hanging rods and can minimize the deformation of the center hole.

[0024] After the product is hung, it can be installed on the matching equipment tooling through the buckle structure and plug-in part of the tooling board. The tooling board can also be used on both sides, and the spare side can be self-shaped during heat treatment to increase its service life.

[0025] The above description only describes the specific implementation methods of the utility model. Various examples do not limit the essential content of the utility model. Ordinary technicians in the relevant technical field can modify or deform the specific implementation methods described above after reading the description without departing from the essence and scope of the utility model.
