Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum heat treatment furnaces, in particular to a vacuum heat treatment furnace which is convenient for feeding and discharging materials. Background Art

[0002] Vacuum heat treatment refers to the heat treatment process that is carried out in whole or in part under a vacuum state. It has the advantages of fast heating and cooling, no surface oxidation, decarburization and carburization, etc. When the vacuum heat treatment furnace works, the internal air pressure is reduced before heat treatment. Therefore, the outside of the furnace body is usually connected to a vacuum equipment, etc., which leads to its loading and unloading usually relying on automated equipment. The existing vacuum heat treatment feeding and unloading mechanism, such as the vacuum heat treatment furnace disclosed in application number CN202320098702.2, which is convenient for loading and unloading, can realize that when one storage slot is in the furnace body for heat treatment, another storage slot can be loaded and unloaded, thereby improving the heat treatment efficiency of the furnace body.

[0003] However, in actual use, since a vertical support plate is usually provided in the vacuum heat treatment furnace to prevent the inner wall of the heat treatment furnace from contacting with the workpiece and the pallet and being damaged, different pallets are needed for loading, and the sizes of the material holding pallets required for different products are also different. The structure of the existing feeding and unloading mechanism of the vacuum heat treatment furnace is fixed and cannot be adjusted, and the scope of application is small. It cannot meet the lifting requirements of different pallets. In particular, it cannot be raised or lowered, which further narrows the scope of application scenarios. In addition, the direct sliding out of the pallet can easily cause the vertical plate to wear or deform. For this reason, we propose a vacuum heat treatment furnace that is easy to feed and unload to solve the above problems. Utility Model Content
