A fine-blanking device for medium and high carbon steel based on ultrasonic waves

Abstract

The invention discloses an ultrasonic-wave-based medium-high carbon steel fine blanking forming device. According to the ultrasonic-wave-based medium-high carbon steel fine blanking forming device, on one hand, an ultrasonic generation system is added, dislocation density of materials is increased and internal frictional force of the materials is reduced during a forming process due to the fact that ultrasonic waves are transmitted to a die and blank, and the resistance to deformation of a to-be-machined machine part is remarkably reduced under a coupling function of alternating stress fields generated through the ultrasonic waves and stress fields generated through elasticoplastic deformation and on the other hand, a temperature feedback adjusting system is added and a centralized control mode through a microcomputer control system is adopted to keep a best vibrational frequency of the ultrasonic waves during a fine blanking process and improve the forming efficiency and accuracy. The ultrasonic-wave-based medium-high carbon steel fine blanking forming device has the advantages of being high in machining and forming accuracy and low in noise, enabling the service life of a stamping device to be long and being applicable for fine blanking and forming of various medium-high carbon steel materials.
