Abstract
Wynalazek dotyczy budowy przyłącza termoparowego do pieca próżniowego, znajdującego zastosowanie w piecach do obróbki cieplnej przedmiotów metalowych. Przyłącze termoparowe składa się z co najmniej jednej pary styków stałych (12a, 12b), zlokalizowanych w strefie gorącej (3b) komory grzejnej (3), połączonych przewodami (15a, 15b) i przedłużką termoparową (17) z urządzeniem pomiarowym (19) oraz odpowiadającej im jednej pary styków ruchomych (10a, 10b) zamocowanych do elementu nośnego (6), na którym posadowiony jest obrabiany wsad (7), połączonych przewodami (9a, 9b) z termoparą (8) zamocowaną do wsadu (7). Wprowadzenie elementu nośnego (6) z wsadem (7) do komory grzejnej (3b) i obniżenie o wartość (x) powoduje najechanie nad siebie pary styków ruchomych (10a, 10b) i ich zwarcie z odpowiednimi stykami stałymi (12a, 12b), co umożliwia dokonanie odczytów temperatury mierzonej przez termoparę (8). Każdy styk stały (12a, 12b) i styk ruchomy (10a, 10b) zbudowany jest z rdzenia ceramicznego, na który ciasno nawinięty jest drut termoparowy (15a, 15b), przy czym osie styków stałych (12a, 12b) są prostopadłe do osi styków ruchomych (10a, 10b) i są w stosunku do styków ruchomych (10a, 10b) obniżone o wartość (x), co po obniżeniu elementu nośnego (6) powoduje zwarcie styków ruchomych (10a, 10b) ze stykami stałymi (12a, 12b) i umożliwia dokonywanie pomiarów. Na wsadzie (7) może być zamocowana większa ilość termopar (8) i wówczas wystąpi również większa ilość par styków ruchomych (10a, 10b) oraz odpowiadających im styków stałych (12a, 12b), najlepiej usytuowanych we wspólnych płaszczyznach poziomych.The invention relates to the construction of a thermocouple connection for a vacuum furnace that is used in furnaces for heat treatment of metal objects. The thermocouple connection consists of at least one pair of fixed contacts (12a, 12b), located in the hot zone (3b) of the heating chamber (3), connected by wires (15a, 15b) and a thermocouple extension (17) with the measuring device (19) and corresponding to one pair of movable contacts (10a, 10b) attached to the support element (6) on which the processed charge (7) is placed, connected by conductors (9a, 9b) with a thermocouple (8) attached to the charge (7). Inserting the support element (6) with the charge (7) into the heating chamber (3b) and lowering it by (x) causes the pair of movable contacts (10a, 10b) to collide and short-circuit with the corresponding permanent contacts (12a, 12b), which enables readings of the temperature measured by the thermocouple (8). Each fixed contact (12a, 12b) and movable contact (10a, 10b) is made of a ceramic core on which a thermocouple wire (15a, 15b) is tightly wound, with the axes of the permanent contacts (12a, 12b) perpendicular to the axis of the contacts movable (10a, 10b) and are in relation to movable contacts (10a, 10b) reduced by the value (x), which after lowering the support element (6) causes shorting of movable contacts (10a, 10b) with permanent contacts (12a, 12b) and allows measurements. A larger number of thermocouples (8) can be attached to the charge (7), and then there will also be a greater number of pairs of movable contacts (10a, 10b) and their corresponding permanent contacts (12a, 12b), ideally located in common horizontal planes.
