Because the heating, cooling and other operations of metal workpieces need dozens or even dozens of actions to complete. These actions are carried out in the vacuum heat treatment furnace, which is inaccessible to the operators. Therefore, the automation level of the vacuum heat treatment furnace is required to be high. At the same time, some actions, such as after the completion of heating and heat preservation, the quenching process of metal workpiece must be six or seven actions and completed within 15 seconds. Such agile conditions to complete many actions, it is easy to cause the operator's tension and constitute misoperation. Therefore, only higher automation can coordinate accurately and timely according to the procedures.
The vacuum heat treatment of metal parts is carried out in a closed vacuum furnace, and the strict vacuum sealing is well known. Therefore, it is of great significance to obtain and adhere to the original air leakage rate of the furnace and ensure the working vacuum of the vacuum furnace to ensure the quality of vacuum heat treatment of parts. So a key problem of vacuum heat treatment furnace is to have a reliable vacuum sealing structure. In order to ensure the vacuum performance of the vacuum furnace, a basic principle must be followed in the structural design of the vacuum heat treatment furnace, that is, the furnace body should adopt airtight welding, and at the same time, the furnace body should be opened or not, and the dynamic sealing structure should be used or avoided, so as to minimize the opportunity of vacuum leakage. The components and accessories installed on the vacuum furnace body, such as water-cooled electrode and thermocouple export device, must also be designed with sealing structure.
