Description
Известные способы изготовлени штампов дл листовой штамповки обт жкой -с использованием схватывающего вещества, затаолн ющего мастер-форму, требуют больших затрат времени.The known methods for producing stamping dies for sheet metal stamping using a grasping agent that tarnishes the master mold are time consuming.
Описываемый способ упрощает и ускор ет процесс их изготовлени . Он отличаетс тем, что в качестве схватывающего вещества используют воду, заливаемую в резиновую оболочку, которую помещают в мастерформу и замораживают.The described method simplifies and accelerates the process of their manufacture. It is characterized in that water which is poured into a rubber casing, which is placed in a master mold and frozen, is used as a grasping substance.
На фиг. 1 схематически изображена мастер-форма в поперечном разрезе; на фиг. 2-то же, в продольном разрезе.FIG. 1 shows schematically a master form in cross section; in fig. 2 is the same in longitudinal section.
Мастер-форма представл ет собой легкий металлический корпус / сварной конструкции, внутри которого помещен резиновый мешок 2. Внутри резинового мешка 2 устанавливаетс холодильный коллектор 3 и термоэлектрические нагреватели 4, укрепленные на стенках корпуса /. Описываемый способ изготовлени щтампов дл листовой щтамповки обт жкой заключаетс в том, что резиновый мещок 2 корпуса 1 предварительно наполн ют через отверстие 5 водой.The master form is a light metal case / welded structure, inside of which a rubber bag 2 is placed. Inside the rubber bag 2 is installed a cooling manifold 3 and thermoelectric heaters 4 fixed to the walls of the case /. The described method for producing sheet scrapers for scraping is that the rubber aperture 2 of the housing 1 is pre-filled through the opening 5 with water.
В узлах 6 фиксируетс эталонна деталь 7 или шаблон. После этого в мещок 2 подкачиваетс вода до тех пор, пока верхн часть мещка 2 не примет форму внутренней поверхности эталонной детали 7. Затем через отверсти 8 холодильното коллектора 3 пропускаетс охлаждающа жидкость, например раствор аммиака, и вода в мещке 2 замораживаетс до твердого состо ни . Эталонна деталь снимаетс .Nodes 6 fixes the reference part 7 or pattern. Thereafter, water is pumped into the cell 2 until the upper portion of the cell 2 takes the form of the inner surface of the reference part 7. Then a cooling liquid, such as ammonia solution, is passed through the openings 8 of the cooling tower of the collector 3, and the water in the cell 2 is frozen to solid state . The reference part is removed.
Дл уменьщени коэффициента трени внешн поверхность натираетс графитным порошком, после чего мастер-форма готова дл листовой щтамповки обт жкой.To reduce the coefficient of friction, the external surface is rubbed with a graphite powder, after which the master form is ready for sheet wrapping.
После использовани мастер-формы с замороженной поверхностью данной конфигурации в холодильный коллектор 3 прекращаетс подача охлаждающей жидкости. При помощи термоэлектрических нагревателей 4 лед в мещке 2 превращаетс в воду. Вода из мещка 2 выкачиваетс , и мастер-форма принимает первоначальный вид.After using the master mold with the frozen surface of this configuration, the coolant supply is stopped in the cooling manifold 3. With the help of thermoelectric heaters 4, the ice in the cell 2 is turned into water. The water from room 2 is pumped out and the master shape takes on its original appearance.
