Manufacturing method and equipment of unequal-section bimetal transmission part

Abstract

The invention relates to a manufacturing method and equipment of an unequal-section bimetal transmission part. The unequal-section bimetal transmission part is manufactured in a near net way by adopting an external-field composite band model forcing temperature control sequence growth integer welding forming technology and in-situ alloying bimetal gradient materials. With the method, electromagnetic stirring action, electromagnetic metallurgy action and ultrasonic welding action are generated; the solidifying process of liquid metal inside a large-size welding pool is integrally controlled; and the manufacturing method of the unequal-section bimetal transmission part is realized under the matching of a high-speed wire feed system, a band model forcing temperature control system, a near net forcing sequence growth integer forming system and the in-situ alloying bimetal gradient materials. The device is formed by integrally assembling an electromagnetic welding system, an ultrasonic welding system and a high-efficiency welding system; according to the method and equipment for fast welding and manufacturing the unequal-section bimetal transmission part by adopting a non-layered welding line structure in a low-cost manner, the manufacturing period is reduced, the reduction efficiency is increased and high reliability and long service life of the unequal-section bimetal transmission part are ensured.
