Mechanical auxiliary vibration die device

Abstract

A mechanical auxiliary vibration die device comprises a vibration die frame, a forming die frame connected with the vibration die frame and a vibration mechanism. The vibration mechanism comprises an equal-width rectangular sleeve and an eccentric wheel arranged in the equal-width rectangular sleeve. One end of the equal-width rectangular sleeve is connected with the vibration die frame. The vibration die frame comprises a vibration die frame upper die plate and a vibration die frame lower die plate, and the vibration die frame upper die plate and the vibration die frame lower die plate are connected through guide column guide sleeves and springs. The forming die frame comprises a forming die frame upper die plate and a forming die frame lower die plate, and the forming die frame upper die plate and the forming die frame lower die plate are connected through a guide column guide sleeve. The vibration die frame is driven by the mechanical vibration mechanism, vibration is transmitted to the forming die frame, and the vibration transmission stability is effectively guaranteed through the large-area die plates and the high-precision guide column guide sleeves; and compared with hydraulic vibration, no oil leakage risk exists, the reliability is improved, and the forming die frame is connected with forming equipment through the vibration die frame, so that the machining capacity of the forming equipment is not influenced.

Description

technical field [0001] The invention relates to a technology in the field of material processing, in particular to a mechanical auxiliary vibration mold device. Background technique [0002] In the process of plastic processing of metal materials, in order to overcome the flow stress of the material itself during the deformation process, it is necessary to apply a large enough deformation force to it, and the corresponding mold structure needs to bear a large load, and at the same time, the surface of the mold will be subject to a relatively large force. Great friction. Severe friction, on the one hand, affects the fluidity of the metal, resulting in partial filling dissatisfaction; on the other hand, it aggravates the wear of the mold and affects the life of the mold. Vibration-assisted method can effectively improve the friction condition during plastic processing. [0003] After searching the prior art, it is found that the Chinese patent document CN104289545A, the publ...
