Description
Согласно изобретению предлагаетс форма дл прессовани фарфоровых опорных изол торов из пресспорошков.According to the invention, a mold is provided for pressing porcelain support insulators from press powders.
Известны металлические формы дл двухстороннего прессовани изол торов из пресспорошков, а также резиновые формы дл гидростатического прессовани этих изделий.Metal molds are known for two-sided pressing of pressurized insulators, as well as rubber molds for hydrostatic pressing of these products.
Предлагаема конструкци представл ет собой комбинированную форму, выгодно сочетающую в себе преимущества металлических форм дл прессовани корпуса изол тора и резиновых форм дл оформлени армируемых полостей его. Изобретение дает возможность повысить качество и удещевить производство изол торов. Это достигаетс тем, что металлические пуансоны дл двухстороннего прессовани обт нуты резиновыми оболочками, которые под действием гидравлического давлени раст гиваютс и оформл ют армируемые полости изол тора.The proposed design is a combined form that advantageously combines the advantages of metal molds for pressing the insulator body and rubber molds for shaping its reinforced cavities. The invention makes it possible to improve the quality and reduce the production of insulators. This is achieved by the fact that metal punches for double-sided pressing are covered with rubber shells, which, under the action of hydraulic pressure, are stretched and form reinforced insulator cavities.
На чертеже изображено устройство формы. В пресс-форму J, помещенную в пресс-камеру 2 засыпаетс порошкообразна фарфорова .масса влажностью 9- 12Vo. Два разъемных полукольца 3 и крыщка 4 служат дл обеспечени выемки издели . Крышка закрывает пресс-камеру и герметизирует внутренний объе.м, затем через штуцер 5 в крышке отсасываетс воздух из камеры. Через определенное врем пуансоны б и 7 с по.мо-щью винтов 5 и 9 перемещаютс один вверх, другой вниз, уцлотн пресспорошок до размеров отпрессованного изол тора. В это.м положении включаетс гидронасос и жидкость под давлением 150 от поступает через штоки 10 и 11 в резиновые оболочки 12 и J3. Эти оболочки, раздува сь, прессуют изол тор. Затем снимаетс гидравлическое давление , убираетс крыщка 4с верхним пуансоном 7, снимаютс крышки М и с помощью специальных т г раздвигаютс полукольца 3. Иуансон 6, двига сь вверх, винтом 8 выталкивает отпрессованный изол тор.The drawing shows the device form. In the mold J, placed in the press chamber 2, powdered porcelain is poured. The mass of moisture is 9-12Vo. Two detachable half rings 3 and a lid 4 are used to provide a notch for the product. The lid closes the press chamber and seals the inner volume, then through the fitting 5 in the lid the air is sucked out of the chamber. After a certain time, the punches b and 7 with the help of screws 5 and 9 move one up, the other down, and press the press powder to the size of the pressed insulator. In this position, the hydraulic pump is turned on and the liquid under pressure 150 comes from the rods 10 and 11 into the rubber shells 12 and J3. These shells, puffing out, press an insulator. Then, the hydraulic pressure is removed, the lid 4c is removed with the upper punch 7, the caps M are removed and with the help of special t-ps the half-rings 3 are pushed apart.
