Description

Technical Field

[0001] The utility model relates to the field of heat treatment, in particular to a vacuum heat treatment box for die steel. Background Art

[0002] Die steel is a type of steel specifically used for manufacturing molds, such as cold blanking dies, cold stamping dies, cold drawing dies, hot forging dies, hot extrusion dies, and die-casting dies. It exhibits high hardness, strength, wear resistance, and corrosion resistance. Die steel is widely used in various fields, including automotive, electronics, home appliances, aerospace, medical devices, and construction. For example, in automotive manufacturing, die steel is used to manufacture various components, including vehicle bodies, doors, roofs, and windows. In electronics manufacturing, die steel is used to manufacture components such as housings, keyboards, and connectors for mobile phones, computers, and flat-screen TVs.

[0003] Heat treatment of mold steel is a key process. It promotes changes in the internal structure of mold steel through heating, insulation and cooling, thereby obtaining the required mechanical properties such as strength, toughness, wear resistance, etc. The vacuum heat treatment box is a device specially designed for heat treatment of mold steel in a vacuum environment. It can form and maintain a high vacuum degree in the furnace, which helps to reduce oxidation and decarburization during the heat treatment process and protect the surface quality of the mold steel.

[0004] The process of taking out the treated mold steel from the existing heat treatment box is inconvenient. After opening the cover, the clamp needs to be inserted into the heat treatment chamber to clamp the surface of the mold steel, and then drag it to the opening of the heat treatment chamber. Finally, the mold steel is taken away by a crane, etc. When dragging the mold steel to the opening of the heat treatment chamber, due to the relatively large weight of the mold steel, a lot of force is required for dragging, and it is also easy to cause unstable clamping and detachment. The same is true when placing the mold steel into the heat treatment chamber. Utility Model Content
