Description

Technical Field

[0001] The utility model relates to the technical field of metal heat treatment, and more specifically to a metal heat treatment device. Background Art

[0002] At present, in metal casting processes such as gravity casting and low-pressure casting, in order to make the castings have good performance, the castings are usually subjected to a solid solution aging heat treatment process, that is, the castings are placed in a solid solution furnace, kept at 500-535℃ for 4-6 hours, and then moved into water and rapidly cooled to below 100℃ (quenching time 7-8min), and then moved into an aging furnace and heated to a certain aging temperature of 150-220℃, kept for 4-6 hours, and aging stress relief treatment is performed to obtain the required mechanical properties of the castings. Solid solution aging heat treatment generally does not change the shape and The overall chemical composition is not changed by changing the internal microstructure of the workpiece, or changing the chemical composition of the workpiece surface, to give or improve the performance of the casting. Heat treatment refers to the metal material in the solid state, by means of heating, insulation and cooling, to change the surface or internal chemical composition and organization of the material to obtain the desired properties of a metal; there are many ways to cool the metal casting during the cooling stage of heat treatment. Direct water rinsing is very common, but it is not convenient to regularize the metal casting during the heat treatment process, the device is not convenient to move, it is not convenient to move the workpiece, it is not convenient to process the object, and the work efficiency is reduced.

[0003] Chinese Patent Authorization Announcement No.: CN213977776U, provides a metal heat treatment device, which clamps the lifting rod through multiple limit bolts so that it cannot move downward by gravity, thereby increasing the stability and fixity of the device, and the transport platform is connected to the transport box. The transport platform has side panels, which are connected to the transport box. The transport box has sliding columns, and the side panels have sliding grooves. The sliding grooves are connected to the sliding columns, and the sliding columns slide on the sliding grooves. Objects that need to be heat treated are placed in the transport box, and the objects can be easily and simply placed in the placement box through the slide, thereby reducing the danger of manual material discharge and increasing the ease of operation of the device. However, when heating for heat treatment, it is necessary to heat it at a constant temperature for a long time to make the chemical composition and organization of the surface or internal material of the metal. At the same time, the heating temperature and the uniformity of heating will affect the performance of the metal. The temperature difference always exists in the traditional flame heating method, which will greatly affect the metal heat treatment effect.

[0004] Therefore, a metal heat treatment device is proposed to solve the above problems. Utility Model Content
