Description
чими полост ми, н выбрасываетс через верхний торец формы в атмосферу.through the upper end of the mold into the atmosphere.
При разъеме формы вентил торный воздух не поступает на ее охлаждение. В этот период времени соленоидный клапан 7 открываетс и через трубки 6 подаетс сжатый воздух, который проходит в воздухозаборную воронку 4 с достаточно высокой скоростью м/с н создает эжектирующий эффект, за счет чего в диффузор 5 и воронку 4 засасываетс воздух из окружающей среды. Сечение трубок 6 и давление сжатого воздуха подобраны таким образом, что коэффициент эжекции равен -- 3, при этом скорость воздуха в фасонном канале 3 - --20 м/с (т. е. така же, как и при закрытой форме). Таким образом, в течение всего цикла формовани перемычка охлал даетс воздухом с посто нным расходом.When the connector of the form fan air is not supplied to its cooling. During this period of time, the solenoid valve 7 opens and compressed air is supplied through the tubes 6, which passes into the air intake funnel 4 at a sufficiently high speed m / s and creates an ejecting effect, due to which air from the environment is sucked into the diffuser 5 and the funnel 4. The cross-section of the tubes 6 and the pressure of compressed air are chosen in such a way that the ejection coefficient is -3, while the air velocity in the shaped channel 3 is -20 m / s (i.e., the same as with the closed form). Thus, during the entire molding cycle, the jumper is cooled with air at a constant rate.
Использование формы с предлагаемой комбинированной системой охлаждени в практике производства стеклоизделий позвол ет увеличить производительность стеклоформующего автомата, стабилизировать температурный режим работы формы, создавать изотермичность на рабочих поверхност х , т. е. увеличить срок ее эксплуатации и повысить качество стеклоизделий.The use of the mold with the proposed combined cooling system in glassware manufacturing practice allows increasing the productivity of the glass forming automat, stabilizing the temperature mode of the mold, creating isothermality on the working surfaces, i.e., increasing its service life and improving the quality of glassware.
Опробывание стеклоформ с комбинированной системой охлаждени на автомате ВВ-12 показало, что тепловой режим работы форм вл етс стабильным, отсутствует перегрев отдельных участков. В результате этого долговечность стеклоформ увеличилась более чем в 3 раза, а производительность автомата - на 5-10%.Testing the glass molds with the combined cooling system on the BB-12 automatic machine showed that the thermal mode of operation of the molds is stable, there is no overheating of individual sections. As a result, the durability of glass forms increased by more than 3 times, and the performance of the machine - by 5-10%.
