Sealing device for part surface treatment

Abstract

The invention provides a sealing device for part surface treatment, and belongs to the field of part processing equipment; the sealing device for part surface treatment includes a furnace body arranged at the outermost; the inner wall of the furnace body is provided with a thermal insulation layer, the thermal insulating layer is made of a foam material, and a sealing door is arranged on one sideof the furnace body; a silicone rubber seal ring is arranged between the sealing door and the furnace body, is fixed at the periphery of the sealing door and has an arc shape outwardly raised; the silicone rubber seal ring is arranged in a manner of protruding the height of the sealing door. The sealing device has good sealing performance and high degree of automation.

Description

technical field [0001] The invention belongs to the field of part processing equipment and relates to a sealing device for part surface treatment. Background technique [0002] There are many kinds of hydraulic power generation parts, and the application environment of hydraulic discovery parts is relatively diverse, and they need to be immersed in water for a long time. Therefore, the anti-corrosion performance of the parts is particularly high. Each part needs to be heat treated after processing to eliminate Oxidation and decarburization of the surface of the workpiece can obtain a clean surface without a metamorphic layer and improve the performance of the parts. Multiple vacuum functional chambers, vacuum pre-evacuation chamber, vacuum welding chamber, vacuum annealing chamber, cooling chamber, etc., the parts to be processed need to be transferred between each functional chamber. During the transfer process, if manual transfer is used, otherwise the efficiency will be r...

[0002] There are many kinds of hydraulic power generation parts, and the application environment of hydraulic discovery parts is relatively diverse, and they need to be immersed in water for a long time. Therefore, the anti-corrosion performance of the parts is particularly high. Each part needs to be heat treated after processing to eliminate Oxidation and decarburization of the surface of the workpiece can obtain a clean surface without a metamorphic layer and improve the performance of the parts. Multiple vacuum functional chambers, vacuum pre-evacuation chamber, vacuum welding chamber, vacuum annealing chamber, cooling chamber, etc., the parts to be processed need to be transferred between each functional chamber. During the transfer process, if manual transfer is used, otherwise the efficiency will be reduced. Slow, and the parts are in contact with the external environment, which affects the subsequent heat treatment process of the parts. Therefore, the continuous heat treatment process can achieve better efficiency. It is necessary to set up a mobile device to realize the conversion between functional rooms. At the same time, it is necessary to ensure that the heat treatment furnace tightness
