APPARATUS FOR MEASURING REAL TIME TO STRAIN MATERIAL BY DIELESS INCREMENTAL FORMING

摘要

A device for measuring a deformation of progressive forming in real time is provided to prevent a forming defectiveness of a product and to observe a deformation of a grid rapidly and accurately. In a device for measuring a deformation of progressive forming in real time forming a material(30) into a product with a desired shape by transferring upper and lower jigs and a stylus(12) when contacting an end portion of the stylus on the material fixed by the upper and lower jigs, a high-resolution camera(40) with a high-magnification lens is mounted at a lower surface of an upper end plate(10) to picture a contact portion between the stylus and the material in real time. The camera is connected with a computer to display a pictured image on a monitor in real time. A grid(32) is indicated at a surface of the material to observe a rupture and an excessive deformation of the material when processing the stylus, accurately through the monitor.
