Process for producing suspension type disc type porcelain insulator by isostatic pressing dry method
The invention discloses a process for producing a suspension type disc type porcelain insulator by an isostatic pressing dry method. The process comprises the following steps of filling powder into alower die made of a metal material in an isostatic pressing die; sealing the lower die by using an upper die made of a rubber material; mounting an inner die with a water inlet guide pipe on the upperdie; putting a forming die into a vibration table for vibrating until the inner die and the water inlet guide pipe penetrate into the lower die; hoisting the forming die into a pressure container cylinder of an isostatic pressing machine; pumping a pressurizing medium into the pressure container cylinder; pressing the powder to the lower die at the lower part by applying pressure outside the upper die to obtain a blank of the required shape; turning the inner and outer surfaces of the pressurized blank by adopting a cutter with a diamond cutter head; immersing the turned blank into a glaze slurry tank for glazing; after transferring the blank out of the glaze slurry tank, carrying out drying by hot air; and after drying, putting the blank into a sintering tray and putting the sintering tray into a kiln to be sintered. According to the process disclosed by the invention, the process time before sintering is shortened to one day, the production period is shortened and the production cost is saved.
本发明公开了一种等静压干法生产悬型盘式瓷绝缘子的工艺，粉料灌入等静压模具中的金属材质的下模具内，用橡胶材质的上模具封住下模具，在上模具装上具有进水导管的内模，将成型模具放入振动台振动，直至内模和进水导管深入下模具内，将成型模具吊入等静压机的压力容器缸内，向压力容器缸内泵入加压介质，通过施压在上模具外的压力把粉料压向下部的下模具，得到所需形状的坯件；加压制成后的坯件采用具有金刚石刀头的刀具对坯件的内、外表面进行车削；车削好的坯件浸入釉浆池上釉；坯件转出釉浆池后用热风干燥；干燥后坯件放入烧成托盘，装入窑炉进行烧成。本发明将烧成前的工艺时间缩短成一天，缩短了生产周期，节省生产成本。
