Description
Technical Field
The utility model relates to a metal carburization heat treatment frock field, concretely relates to combination charging tray frock that bearing rolling element carburization heat treatment used.
Background
In the carburizing heat treatment process of the bearing rolling element, the rolling element is generally placed in a tray and then subjected to heat treatment. The existing common material tray is easy to deform after being frequently used for a period of time in a high-temperature and high-carbon environment, the bottom of the material tray directly leads to the fact that the rolling bodies cannot be placed at vertical intervals after deformation, the rolling bodies are placed in disordered contact, the heat treatment charging amount can be reduced, and carburization indentation is generated to cause the phenomenon that a matrix carburization layer is not uniform.
Consequently, can produce and realize that the orderly vertical interval of rolling element is put, and guarantee that difficult deformation under the operating mode of long-time use in high temperature, high carbon potential environment to the heat treatment charging tray frock of increase charge volume as far as possible is the problem that needs solve in the bearing heat treatment process urgently.
Based on this, chinese patent application No. 201920348244.7 provides a large-sized spherical bearing roller heating tray. The heating tray for the large-size spherical bearing roller is provided with a square frame, wherein the bottom surface of the square frame is provided with a plurality of horizontally arranged heat-resistant steel wires I and a plurality of vertically arranged heat-resistant steel wires II; a plurality of heat-resistant steel wires I and heat-resistant steel wires II are interwoven into a material tray net with a plurality of square meshes; the heat-resistant steel wire I and the heat-resistant steel wire II are both in a wave shape formed by bending; a plurality of wavy heat-resistant steel wires I and a plurality of wavy square-hole meshes are interwoven into a whole; the wave crest of the wave-shaped square hole meshes forms a contact point with the spherical bearing roller, and a multi-point contact structure is formed between the heating tray and the spherical bearing roller. Although the problem of uniformity of a bearing layer at the bottom of the material tray and a carburized layer of a large-size spherical bearing is solved, the heating material tray occupies a large area, cannot be suitable for a heating furnace with a partition plate in the middle, and cannot flexibly adapt to the specification of rolling bodies, so that the waste of space in the heating furnace is caused.
Disclosure of Invention
The utility model aims at providing a bearing rolling element carburization heat treatment combination charging tray frock for the charging tray can use and stack the combination from top to bottom by the individual layer combination, and the charging tray uses also indeformable for a long time, has improved production efficiency, has solved the problem of mentioning in the background art.
In order to achieve the above object, the present invention is realized by:
a combined material tray tool for carburizing bearing rolling elements comprises 42 mutually independent combined material trays, wherein each material tray comprises a material tray wall, a material tray bottom, two pillars, and clamping strips and clamping grooves at the edges of the material tray wall; the combined material tray can be combined by a plurality of material trays in a single layer or combined by being overlapped up and down.
In a further improvement, the 6 fan-shaped combined material trays can form a single-layer circular material tray station.
Further improved, the positions of the clamping strips and the clamping grooves on the upper part and the lower part of the tray wall are in one-to-one correspondence.
In a further improvement, the cross sections of the two pillars are hollow in a shape like a Chinese character 'pin'.
In a further improvement, the combined tray can be stacked into seven layers at most.
Preferably, the combined material tray is made of Cr25Ni20 material manufactured through a casting process.
The utility model has the advantages that: the combination form of the fan-shaped material discs can be used in a single layer or in a multi-layer overlapping manner, so that the charging amount of heat treatment is increased, the ordered vertical interval arrangement of the rolling elements is realized, and the consistency of the thickness of the carburized layer of the rolling elements is ensured through different combination forms; the regular octagonal reticular structure of the material tray ensures the gas circulation in the carburizing heat treatment process, so that the matrix carburized layer is more uniform, and the bottom plane of the material tray is kept flat and is not easy to deform in the long-term use process of the material tray in a high-temperature and high-carbon potential environment; and the material of this design is few, can be according to the actual independent assortment of production to polygonal pillar is littleer than cylindrical pillar occupation space, can improve the charge volume of rolling element, can adapt to multiple operating mode.
