FORGING PROCESS EMPLOYING SUPERIMPOSITION OF VIBRATORY FORCES CONCURRENTLY WITH NORMAL FORGING FORCES

Abstract

INVESTIGATION OF THE EFFECT OF SUPERIMPOSED VIBRATORY FORCES OVER STATIC FORGING PRESS FORCES ON METAL DEFORMATION SHOW THAT SUPERIMPOSED PULSATING LOADS OF FREQUENCIES OF 120AND 180 CPS EXHIBIT DIFFERENT METAL DISPLACEMENT EFFECTS THAN STATIC FORCES OF EQUAL MAGNITUDE. An electromagnetic vibrator, used with both a 1,000-ton press and a 1,000-ton hydraulic jack, proved to be a feasible means of generating pulsating forces at 120 and 180 cps. A low range force frequency of 60 cps with sufficient force magnitude could not be produced by this vibrator. (Author)
