Abstract:

In view of the large-scale underground mining cost, lack of spare parts, repair costs, once the interruption of the damage production line, this paper focuses on the 3D print laser forming repair technology in the application scope of repair machine vulnerable equipment and application prospect in the application of 3D based on, the laser repair technology feasibility of direct printing works, mining equipment vulnerable parts of structure type, transmission system of three types of equipment, and parts of machine equipment used in laser cladding surface strengthening technology of difference and advantage, the 3D print laser repairing mine equipment parts, can avoid or reduce the mechanical processing after repair, to copying precisely repair, improve mine the equipment and the service life of wearing parts, in mining equipment repair with technological advantages and application prospects.

Key words: 3D print, Laser Repair, Copying Precisely Repair, Chine Vulnerable Equipment, Direct Work Pieces, Structure Type, Transmission System
