Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing die coatings, and more specifically, to a vacuum furnace for processing wire drawing die coatings. Background Art

[0002] Wire drawing die coating is a special coating applied to the surface of the wire drawing die. Wire drawing die coating plays a vital role in the wire drawing process. During the wire drawing process, the coating can significantly reduce the friction coefficient between the die and the wire, which makes the drawing process smoother and reduces the drawing force, thereby reducing the load requirements on the equipment and also reducing energy consumption.

[0003] At present, traditional heat treatment or coating processing methods are carried out in air, which can easily cause oxidation and decarburization on the surface of the wire drawing die substrate, resulting in a decrease in the hardness, strength and other properties of the substrate. However, vacuum furnaces are used for processing in a vacuum environment, and there is almost no problem of oxidation and decarburization, which can well protect the original properties of the wire drawing die substrate.

[0004] However, when using a vacuum furnace to coat the wire drawing die, the shapes and sizes of the wire drawing dies are different. If the same vacuum furnace is used to process the wire drawing dies, the coating effect cannot be guaranteed. A vacuum furnace for wire drawing die coating processing is now proposed to improve the existing problems. Utility Model Content
