DEVICE TO BRAZE PARTS Russian patent published in 1996 - IPC

FIELD: welding. SUBSTANCE: device to braze parts has inductor anchored on plate of table and connected to induction current power supply unit and water cooling system, clamping fixture for parts placed outside of inductor and mechanism feeding parts into inductor. Spring-loaded centering catcher is placed on plate above inductor. Device is also supplemented with electric air-operated valve coupled to pneumatic actuator to feed compressed air to parts in inductor, power supply source, time relay, limit switch interacting with mechanism feeding parts into inductor and sensor of relative position of parts which mobile contact is rigidly coupled to spring-loaded centering catcher and is electrically connected through limit switch to one of terminals of power supply source, time relay and electric air-operated valve are intercoupled electrically and connected to second terminal of power supply source. Immobile contact of sensor of relative position of parts is connected to time relay. Induction current power supply unit operates on medium frequency. Device is equipped with warning lamps for visual control of start of melting of spelter and finish of brazing process, one of them is placed in electric circuit in parallel to time relay and second one is connected in parallel to electric air-operated valve. EFFECT: increased operational efficiency and reliability. 2 dwg
