Multi-physical field auxiliary laser cladding device

Abstract

The invention relates to a multi-physical field auxiliary laser cladding device which comprises a rack, a magnetic field generating device, an ultrasonic generating device, a stress tensioning deviceand an electric field generating device. The rack is composed of a bottom plate, L-shaped arm supports and a sliding rail, the sliding rail is fixed to the middle of the bottom plate and can be fixedand locked, one end of each of the two L-shaped arm supports is assembled on the sliding rail, and the other ends of the two L-shaped arm supports are connected with the stress tensioning device; thestress tensioning device is composed of a clamp, an insulating spacer and a hydraulic cylinder, after the clamp clamps a sample, the hydraulic cylinder applies tension, and the insulating spacer is arranged between the sample and the clamp to isolate current; the magnetic field generating device is formed by welding three pairs of coils which are similar in size and perpendicular to one another, and an adjustable magnetic field can be formed in the X direction, the Y direction and the Z direction; the ultrasonic generating device is composed of an ultrasonic generator, an energy converter anda Y-shaped connecting rod, the ultrasonic generator is arranged on the bottom plate and is sequentially connected with the energy converter, the Y-shaped connecting rod and the sample, and a groove coated with an insulating layer is formed in the upper part of the Y-shaped connecting rod, and the groove is fastened with the sample through a screw and a pressing plate; and the electric field generating device is composed of a power source and a wire connected with the two ends of the sample. The device has the advantages of being simple in structure, practical, stable and adjustable in force-electricity-magnetism-sound multi-parameter.

Description

Technical field: [0001] The invention belongs to the field of advanced manufacturing technology, and in particular relates to an adjustable force-electricity-magnetism-acoustic multi-physical field generating device suitable for laser cladding. Background technique: [0002] Laser cladding is a laser processing method that increases the surface hardness of the substrate and improves the wear resistance, corrosion resistance, high temperature resistance, oxidation resistance and electrical properties of the substrate surface. It refers to placing the alloy powder on the surface of the substrate to be clad with a specific filler, and irradiating with a certain intensity of the laser beam, so that the powder and a small part of the surface of the substrate are simultaneously melted on the surface of the part, and rapidly solidified with the substrate. Form a cladding layer in a metallurgical bonded state. Compared with other remanufacturing technologies, laser cladding technol...

AI Technical Summary

Problems solved by technology

Strength, frequency, amplitude, and direction cannot be adjusted freely, and the universality is poor, so it cannot meet the production requirements with various parameter requirements

However, the method of electromagnetic induction and ultrasonic vibration used in this device is also accompanied by the defect of excessive heat generation.
