Ultrasonic vibration assisted foil plate precision micro-blanking forming device and method

Abstract

The invention relates to a micro blanking forming device and method, in particular to a supersonic vibration auxiliary foil plate precision micro blanking forming device and method. The problems that existing precision foil plate common blanking forming quality is not high enough, the section quality and the form and location tolerance cannot meet needs, a mould is abraded seriously, and the service life is short are solved, and meanwhile the problems that in the large component vibration auxiliary forming process, energy is hard to transmit, and a vibration system is hard to achieve are solved. An upper mould plate, an upper cushion plate, a stripper plate, a female mould fixing plate, a lower cushion plate and a lower mould plate are sequentially overlapped from top to bottom, an upper cavity is formed by a through hole in the middle of the upper mould plate and a through hole in the middle of the upper cushion plate, piezoelectric ceramics, an oscillator, a male mould fixing block and a puncher pin are sequentially inserted into the upper cavity from top to bottom, a female mould is embedded in the middle of the upper surface of the lower cushion plate, and the lower portion of the puncher pin is inserted into a discharging hole in the middle of the upper surface of the stripper plate. The micro blanking forming device and method are used for the field of machining.

Description

technical field [0001] The invention relates to a micro-blanking forming device and method, in particular to an ultrasonic vibration-assisted precision micro-blanking forming device and method of a foil plate, belonging to the field of mechanical processing. Background technique [0002] The rapid development of microsystem technology and microelectromechanical systems in modern technology has higher and higher requirements for foil plate micro components. Not only the scope of application is expanded, the demand is increasing, but the forming quality of foil plate micro-components also needs to be improved. For example, foil plate micro-components require good punching section quality and high shape and position accuracy while ensuring high geometrical and dimensional accuracy. Wait. Generally, the thickness of these foil micro-components is small, generally less than 0.2mm, and the overall size is only a few millimeters, so it is difficult to carry out secondary processin...
