Abstract

Изобретение относитс к устройству дл электроконтактного нагрева электропроводных деталей. Цель изобретени - расширение номенклатуры обрабатываемых деталей, повышение долговечности устройства. Устройство содержит диэлектрическое основание 1 с расположенными на нем трубами (Т) 2,3 с втулками (В) 4,5 с радиально прикрепленными к ним разноплечими рычагами (Р) 6 - 9 с контактными зажимами по концам. Т 2 и 3 соединены с источником хладоагента, а между собой-Т 12. При подаче напр жени замыкаетс электроцепь: Т 2 - В 4 - Р 9 с зажимом-деталь-Р 6 с зажимом-В 5 - Т 3. За счет того что В 4,5 имеют возможность поворота и осевого перемещени по вл етс возможность устанавливать детали различной длины. Выполнение же охлаждающей системы позвол ет устранить перегрев деталей устройства и тем самым повысить долговечность устройства. 1 з.п. ф-лы, 2 ил.The invention relates to a device for electrocontact heating of electrically conductive parts. The purpose of the invention is to expand the range of workpieces, increasing the durability of the device. The device contains a dielectric base 1 with tubes (T) 2.3 located on it with bushings (B) 4.5 with different-arm levers (P) 6 - 9 radially attached to them with contact clamps at the ends. T 2 and 3 are connected to a source of refrigerant, and among themselves - T 12. When voltage is applied, the electrical circuit closes: T 2 - B 4 - P 9 with a clamp-part-P 6 with a clamp-B 5 - T 3. Due to that That the B 4,5 has the ability to rotate and the axial movement it is possible to install parts of different lengths. The implementation of the cooling system eliminates the overheating of parts of the device and thereby increase the durability of the device. 1 hp f-ly, 2 ill.
