Method for forming plates on basis of vibration by aid of flexible male die

Abstract

The invention discloses a method for forming plates on the basis of vibration by the aid of a flexible male die. Machining equipment for implementing the method mainly comprises a lower die holder, a female die, a blank holder, granular media, a blank holder force applying device, a vibration device, a punch, an upper die holder, guide columns, guide sleeves and the like. The method includes placing a metal plate between the female die and the blank holder when the metal plate is about to be machined and formed, enabling the blank holder to apply blank holder force, then adding the granular media into a barrel formed by the blank holder and the metal plate, enabling a pressure head to compress the media under the effect of pressure, applying the pressure to the plate and performing deep drawing forming on the plate by the aid of the flexible male die; enabling the vibration device to apply vibration on the punch, the blank holder and the female die individually or jointly. The method has the advantages that friction and deformation resistance among the plate and the dies can be reduced under the effect of vibration excitation, the flowability and the force transfer property of the granular media can be promoted, plate forming limit can be upgraded, and the method is favorable for machining and forming components in complicated shapes; the granular media can be reused, accordingly, the die machining cost and energy consumption can be reduced, and the method is favorable for environmental protection.

Description

technical field [0001] The invention relates to a method for forming metal sheets. Background technique [0002] With the rapid development of my country's automobile, aerospace, military and other industries and the requirements for energy saving and consumption reduction, there is an increasing demand for some high-precision, complex-shaped lightweight alloy or high-strength alloy sheet metal parts. However, it is difficult to form these materials by conventional deformation methods, which becomes the bottleneck of their processing and forming. Therefore, the plastic processing technology of such difficult-to-form materials has become a research hotspot. In order to solve the processing problems of such difficult-to-form materials, the current processing methods have problems such as numerous processing passes, complex forming equipment, and high input costs. Contents of the invention [0003] The invention aims to provide a vibration-based sheet material soft punch fo...
