Abstract

The invention discloses a restrictive mold pressing mold for ultrasonic vibration auxiliary demolding and a grain refinement method, and relates to mold machining and manufacturing and an applicationmethod thereof, in particular to a mold capable of enabling workpieces to obtain large accumulation strains and a process method for refining material grain sizes. The restrictive mold pressing mold comprises a mold frame, an ultrasonic auxiliary demolding device and a mold cavity. The ultrasonic auxiliary demolding device and the mold cavity are mounted in the mold frame together. The novel restrictive mold pressing mold for ultrasonic vibration auxiliary demolding and the grain refinement method have the beneficial effects of being novel in structure, easy and convenient to machine and operate, good in workpiece adaptability, uniform in strain distribution and small in wear, facilitating demolding and the like, and integrating economic performance and practicality.

Description

Technical field [0001] The restrictive molding die for assisted demolding by ultrasonic vibration and the method of grain refinement according to the present invention relate to die processing and manufacturing and methods of use thereof, specifically a die capable of obtaining a large accumulated strain of a workpiece, and a material crystal grain Dimensional process method. Background technique [0002] With the rapid development of the automotive, aerospace, and nuclear energy industries, materials with superior mechanical and processing properties have received extensive attention. Reducing the average grain size of metal or alloy materials to the ultra-fine grain range (submicron and below) is an important method to improve its mechanical and processing properties. The specific strength of ultra-fine-grained metal or alloy materials at room temperature Significantly improved, and has high strain rate superplastic properties, which is conducive to precision processing and pl...
