Abstract
The invention provides a vacuum pressure infiltration device and system for a pantograph metal-impregnated carbon sliding plate. The vacuum pressure infiltration device comprises a furnace body, a rotating mechanism is arranged on the lower hem of the furnace body, and the furnace body can rotate anticlockwise and anticlockwise through the rotating mechanism. The furnace body is provided with a furnace door and a hearth, a graphite boat is arranged in the hearth and is provided with two crucibles used for containing different raw materials, and the raw materials in the two crucibles are mixed after the furnace body rotates. The system comprises the vacuum pressure infiltration device and a forklift device used for feeding the graphite boat into the furnace body, and the overall system is placed in a nitrogen environment. The vacuum pressure infiltration device and system overcome the shortcomings that an existing vacuum pressure infiltration technological device is high in requirement and limited in automatic degree, and high-efficiency, low-energy, automatic and continuous production of the pantograph metal-impregnated carbon sliding plate is achieved; near net shaping is achieved, the product density is high, the size accuracy is high, the process is simple, and the controllability is good.
Description
technical field [0001] The invention belongs to the technical field of preparation of pantograph slide plates, and in particular relates to a vacuum pressure impregnation device and system for impregnating metal-carbon slide plates of pantographs. Background technique [0002] Improving the quality of metal-impregnated carbon skateboards for pantographs, accelerating the realization of localization, and breaking through foreign technology blockades are important contents of the current pantograph skateboard industry. Over the years, France, Germany, Japan and other countries have vigorously carried out research on the preparation process of pantograph slides. The preparation methods of pantograph carbon slides mainly include powder metallurgy, high-pressure sintering, vacuum pressure infiltration, etc. At present, the leading products in the market are metal-impregnated carbon slides made by vacuum pressure infiltration, and pure carbon slides occupy a small market. The tra...
