Problems solved by technology
[0002] The traditional heat treatment turnover tray has a mesh structure. When the metal mechanical parts are placed on the tray to heat and quench as a whole, the thermal conductivity of the mesh structure is low, and the quality of the produced product is not high. In this case, the tray produced by non-casting It is prone to cracks and has a high damage rate

Abstract
The invention discloses a novel thermal treatment turnover material disc, and belongs to the technical field of mechanical thermal processing treatment. The novel thermal treatment turnover material disc is characterized in that a disc body is of a hexagonal structure. The novel thermal treatment turnover material disc is simple and practical in structure, and is reasonably designed, enough heat exchange between a quenching medium and a workpiece is guaranteed in a quenching process by utilizing the stability and enough pores of the hexagon, accordingly quenching deformation is reduced, the material disc does not need to be subjected to turnover quenching, the service life of the material disc is prolonged to a large extent, and meanwhile, compared with the prior art, the defects of the material disc are reduced by adopting an integral casting structure. The novel thermal treatment turnover material disc is simple and reasonable in structure, can resist oxidation, is not prone to deforming, and is good in diathermancy and long in service life.
Description
technical field [0001] The invention relates to a revolving tray for heat treatment of metal mechanical parts, which can be used for heat treatment of forgings similar to differential gear front shells and the like. Background technique [0002] The traditional heat treatment turnover tray has a mesh structure. When the metal mechanical parts are placed on the tray to heat and quench as a whole, the thermal conductivity of the mesh structure is low, and the quality of the produced product is not high. In this case, the tray produced by non-casting It is prone to cracks and has a high damage rate. Contents of the invention [0003] The purpose of the present invention is to address the shortcomings of the above-mentioned technologies, to provide a heat treatment of metal mechanical parts with high thermal conductivity and heat dissipation rate, which can meet the uniform heating of large parts, and to use casting technology to produce the material tray. [0004] The techni...
