Description

Technical Field

[0001] The utility model belongs to the field of heat treatment material frames, in particular to a heat treatment material frame with a layer height adjustment structure. Background Art

[0002] Many parts in industry need to be heat treated so that they can obtain the desired performance. In the heat treatment industry, the parts that need to be heat treated are generally loaded into the heat treatment tooling, and then the heat treatment tooling with the parts is placed in the heat treatment furnace for high temperature treatment. Heat treatment tooling generally includes material frames, material trays, material racks, and a combination of material frames and material racks.

[0003] The patent application with publication number CN208794998U discloses a combined material frame for heat treatment, including: a material frame, multiple separation cylinders and multiple material trays, wherein the material frame, multiple separation cylinders and multiple material trays are split structures; the material frame includes a base and five columns, and the interior of the base is provided with multiple circular holes and multiple rectangular holes, which helps to enhance the permeability; the five columns are respectively fixed at the four corners and the middle of the base, and multiple separation cylinders and multiple material trays are layered and spaced on the five columns; each separation cylinder is provided with a first through hole inside, and multiple separation cylinders are used to separate and support multiple material trays; each material tray is provided with five second through holes and multiple discharge units, and the five second through holes are respectively provided at the four corners and the center of the material tray, which are used to set the material tray on the five columns; the multiple discharge units are honeycomb-shaped. The utility model helps to enhance the permeability of parts during heat treatment and improve the heat treatment quality of parts.

[0004] However, the above technology has the following disadvantages when used:

[0005] It is described in paragraph 0027 of the above-mentioned document that "when in use, the parts that need to be heat treated are placed on multiple trays, and separation cylinders are respectively mounted on the five columns of the material frame, and then the trays with the placed parts are mounted; if multiple layers of trays are required, the separation cylinders and the trays are layered and spaced on the five columns to ensure that the parts have sufficient permeability during heat treatment and improve the quality of heat treatment of the parts." It can be seen that multiple separation cylinders are used to separate multiple trays. Although it can enhance the permeability of parts during heat treatment and improve the quality of heat treatment of parts, due to the different specifications of parts, the distance between the two trays during heat treatment will be different. Since the length of the separation cylinder cannot be adjusted, the distance between the two trays cannot be adjusted, and then the position of the tray cannot be adjusted according to the specifications of the parts.

[0006] Therefore, a heat treatment material frame with a layer height adjustment structure is proposed to solve the above-mentioned drawbacks. Utility Model Content
