Abstract

An amplitude modulation type vibration mold device comprises a vibration mold frame, a forming mold frame connected with the vibration mold frame, an amplitude modulation mechanism and a vibration mechanism. The vibration mechanism comprises an ejection rod and an eccentric wheel, wherein the two ends of the ejection rod are connected with the eccentric wheel and the vibration mold frame respectively. The amplitude modulation mechanism is connected with the eccentric wheel so that the eccentric wheel can move. The mechanical vibration mechanism is used for driving the vibration mold frame and transmitting vibration to the forming mold frame, and the vibration frequency and vibration amplitude are controllable and adjustable. A large-area mold plate and a high-accuracy guide pillar guide sleeve are adopted and effectively guarantee the stability of vibration transmission. Compared with hydraulic vibration, the risk of oil leakage is avoided, and the reliability is improved. In addition, the forming mold frame is connected with forming equipment through the vibration mold frame, and the machining capacity of the forming equipment is not affected.

Description

technical field [0001] The invention relates to a technology in the field of material processing, in particular to an amplitude modulation 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 pub...
