Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for PVD coating furnaces, and in particular to an automatic feeding and discharging mechanism for a PVD coating furnace for cutting tools. Background Technology

[0002] PVD coating furnaces utilize phenomena such as thermal evaporation of materials or sputtering generated by bombarding surface atoms with ion beams to form plasma, creating single or multiple layers of coating material on the surface of cutting tools. This improves the tool's hardness, wear resistance, high-temperature oxidation resistance, and high-temperature stability.

[0003] Before entering the PVD coating furnace, all tools need to be clamped onto the rack, and then the rack is pushed into the PVD coating furnace to begin the coating process. Traditionally, the rack is pushed into the PVD coating furnace manually, which is time-consuming and labor-intensive. Workers are also prone to being crushed by the rack during the pushing process, posing a safety hazard. Utility Model Content
