Impregnation device and impregnation method

Abstract

The invention discloses a dipping device used for dipping of workpieces. The dipping device comprises heating furnaces, a dipping furnace and a hoisting mechanism. The heating furnaces are used for heating of the workpieces and dipping mediums. The dipping furnace is arranged on the outer sides of the heating furnaces and used for dipping of the workpieces. The hoisting mechanism is connected on the heating furnaces and the dipping furnace and used for transferring of the workpieces and the dipping mediums. The dipping furnace comprises a furnace shell, a working cavity arranged inside the furnace shell, a dipping pot and a lifting system which are arranged in the working cavity and a vacuum system and a pressure controlling system which are connected on the working cavity. The invention further provides a dipping method. According to the provided dipping device and the dipping method, the continuous type batched treatment of the workpieces can be effectively achieved, the treatment speed of the workpieces is increased, energy loss can be effectively reduced, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of material processing equipment, more specifically, to an impregnation device and an impregnation method. Background technique [0002] The impregnation method is a method commonly used to improve the performance of carbon-based composite materials or ceramic-based composite materials. The metal ions in the impregnation impregnate the material to be treated and penetrate into its inner surface to form a material with superior performance. Among them, the impregnated metal medium generally includes aluminum, copper, titanium and high-temperature alloys. Because impregnation can greatly enhance the performance of materials, impregnation is widely used in aerospace, military and national defense, electronic information, rail transit and other fields. Specifically, when using the impregnation method to process materials, it is often necessary to rely on a special impregnation device. [0003] At present, due to some li...

Problems solved by technology

[0003] At present, due to some limitations in the structural design of the existing impregnation device, when using the existing impregnation device to impregnate workpieces, the impregnation chamber of the impregnation device must be pretreated when each batch of workpieces is processed. (such as vacuuming, heating, pressurizing), then heat the workpiece and the impregnating medium to the specified temperature in the impregnation chamber, then place the workpiece in the impregnation medium for immersion, and then completely cool the workpiece in the impregnation chamber of the impregnation device , and finally take out the cooled workpiece. In this process, the actual time spent on pressure impregnation of the workpiece only accounts for 1 / 6 to 1 / 3 of the entire workpiece impregnation cycle, while a large amount of other time is spent on the pre-heating and In the post-cooling and cooling process, it takes a very long time to impregnate each batch of workpieces, and the processing speed of workpieces is very low. When a large number of workpieces need to be processed, it takes a lot of time; in addition, the heating set in the existing impregnation device Components and insulation materials need to be heated and cooled again after the treatment of the previous batch of workpieces. At the same time, the impregnation medium set in the impregnation device also needs to be heated and cooled again. Such a large amount of heat is directly lost without acting on the impregnation of the workpieces, and the production cost very high
