Индукционный термоусадочный фитинг алюминиевый корпус насоса часть
Цель
This is a Shrink fit Part Removal application. The customer’s current process uses a press to push the inserted part out. However, this requires significant force and time. By applying heat, the housing can expand just enough to allow for the easy removal of the inserted part with minimal force. The customer’s time requirement is to complete the Shrinkfit Part Removal within 7 minutes.
Оборудование
DW-HF-6KW induction heating system
Материалы
- Алюминиевый корпус насоса Наружный диаметр 2,885" (73,279 мм), стенка 0,021" (533 мм)
Основные параметры
Температура: Приблизительно 400°F (204°C)
Power: 5kW
Время: 100 секунд
Процесс:
- Чтобы завершить снятие термоусадочной детали, поместите деталь в катушку так, чтобы верхняя часть корпуса находилась как можно ближе к верхней части катушки.
- Чтобы определить идеальное время и мощность, потребовались некоторые эксперименты. Мы обнаружили, что для извлечения детали идеально подходит 100 секунд, что значительно ниже установленного заказчиком предела в 7 минут.
Результаты/выгоды:
The tested assembly can be heated to the required temperature in less than 7 minutes using the DW-HF-6KW induction heating system and custom designed coil. Heat time for the Custom Coil was 100 seconds, Temperature needed to be close to 400°F (204°C) in order to expand the part sufficiently for removal. The part was removed with some pulling force applied to it as the pump housing was reaching 400°F (204°C).
This Shrink Fit application was further reviewed to determine if a lower power induction system could be used. In this case, the customer’s requirement was 7 minutes, and we achieved the part removal in 100 seconds. Could a lower power system remove the part at a lower cost? A lower power system would be acceptable if our goal is part insertion. For Shrink Fit – Part Insertion, a slower heating rate would still result in a successful process. However, with Shrink Fit – Part Removal, it is important to heat rapidly. A slower heat rate would result in the inserted part also heating, and also expanding. The inserted part potentially would remain “stuck”. By heating rapidly, we avoid this issue. The customer in this case has decided to both use a system for part insertion AND part removal. A 2 kW system is fine for the Shrink Fit – Part Insertion; and the DW-HF-6KW induction heater will be used for the Shrink Fit – Part Removal
