The invention discloses compound linear friction welding equipment which has different vibration force and vibration frequencies in different welding stages and on different materials and is wide in adjustable frequency range. The equipment comprises an upper rack, a lower rack, an upper pressure driving mechanism, a lower pressure driving mechanism, an upper fixture and a lower fixture. During welding, the upper pressure driving mechanism and the lower pressure driving mechanism output opposite acting force; and the compound linear friction welding equipment further comprises a mechanical vibrating device and an electromagnetic vibrating device, the mechanical vibrating device is in transmission connection with the upper fixture or the upper pressure driving mechanism, the electromagneticvibrating device is connected with the lower fixture or the lower pressure driving mechanism, and the directions of vibration generated by the mechanical vibrating device and the electromagnetic driving device are perpendicular to the direction of the acting force output by the upper pressure driving mechanism or the lower pressure driving mechanism. The equipment is applied to the technical field of linear friction welding.
Description
technical field [0001] The invention relates to a linear friction welding device, in particular to a composite linear friction welding device. Background technique [0002] Friction welding is to use the heat generated by the relative frictional motion between the contact surfaces of the weldment under the action of external force to make the contact surface and its adjacent metal reach a viscoplastic state and produce appropriate macroscopic plastic deformation. Welding is accomplished by interdiffusion and dynamic recrystallization. [0003] After years of research, until 1985, Allwood, Searle@Timney Company was responsible for research and design, Blacks Equipment Company was responsible for machine manufacturing, and Rolls-Royce Company provided technical cooperation. Several companies jointly developed the world's first linear friction welding machine. Machine, the frequency of the reciprocating mechanism of this equipment can reach 75Hz, and the displacement range is ...
