Method and equipment for manufacturing gradient functional structure

Abstract

The invention relates to a method and equipment for manufacturing a gradient functional structure through arc welding and quick forming. By adopting the technology of outer-field compounding, molding, forcible temperature control, sequential growth, and whole welding forming, a double metal gradient material is subjected to in-situ alloying, and the gradient functional structure is manufactured in a near net way; and in the method, an electromagnetic stirring action, an electromagnetic metallurgical action and an ultrasonic welding action are adopted, the large-volume welding pool liquid metal solidification process is comprehensively controlled, and the gradient functional structure is manufactured by matching a high-speed wire feed system, a mould forcible temperature control system, a near net forcible sequential growth whole forming system, and an in-situ alloying gradient material. The equipment is formed by integrating and combining an electromagnetic welding system, an ultrasonic welding system, and an efficient welding system. By the method and the equipment for quickly manufacturing the gradient functional structure by a non-layered welding structure in a low-cost way, a manufacturing period is reduced, production efficiency is improved, and the high reliability and the long service life of the gradient functional structure are guaranteed.

[0002] How to give full play to the manufacturing advantages of welding technology and the performance of modern structural materials, and quickly manufacture new high-performance special structural parts / parts / components / devices / systems with high torque, low noise, low energy consumption, and pollution-free (such as special drive shafts, piston rod, high-speed and heavy-duty gears, special rotors and blades, special hub shafts, guide rails, gear rollers, rolls, molds, etc.), especially to solve extreme and special circumstances, lightweight, long life, high reliability, high performance new The problems of high energy consumption, high material consumption, long processing cycle and short service life of special components and their systems are key technologies in the field of important equipment in mechanical engineering

[0003] Under extreme service conditions, the high-performance special parts of the key basic parts of machinery are mainly manufactured from a single overall structural part (such as forging parts, casting parts) after machining, and the consumption of raw materials, energy, manpower and other resources is relatively high. Large, long processing time, extremely high equipment requirements, high cost investment, low yield rate, high manufacturing cost
