Abstract

The invention provides an electromagnetic induction annular heating laser cladding nozzle device and a laser cladding device. The nozzle device comprises a connecting part, an induction coil fixing part, a ceramic inner ring, induction heating coils, an induction heating power supply, a thermocouple and a thermocouple power supply; the induction heating coils are arranged in the induction coil fixing part and is connected to the induction heating power supply; the ceramic inner ring is arranged in the induction coil fixing part, a powder flow channel is formed between the ceramic inner ring and the induction coil fixing part, a thermocouple mounting hole is formed in the ceramic inner ring, and a thermocouple is mounted in the thermocouple mounting hole and connected to the thermocouple power supply; and the connecting part is connected to the ceramic inner ring and the induction coil fixing part, a powder inlet channel communicated with the powder flow channel is formed in the connecting part, and a laser beam channel is formed in the center of the connecting part and the ceramic inner ring. According to the electromagnetic induction annular heating laser cladding nozzle device and the laser cladding device, laser cladding powder is preheated before the powder is converged into a laser beam focus area, and the laser cladding efficiency is improved.

Description

technical field [0001] The invention belongs to the field of advanced manufacturing technology, and relates to an electromagnetic induction annular heating laser cladding nozzle device and a laser cladding device. Background technique [0002] As an advanced manufacturing technology featuring high precision, high performance, small heat-affected zone, low dilution rate and high degree of automation, powder laser cladding technology is widely used in the strengthening or modification of the surface properties of metal parts, surface repair and Metal additive manufacturing and other fields. [0003] The existing powder laser cladding technology uses metal powder and laser beam as the cladding material and heat source. The laser beam melts the powder and the substrate to form a molten pool, and at the same time scans synchronously according to the predetermined route to make the molten pool and the substrate move relative to each other. , so as to form a cladding layer that me...
