Abstract
With the use of clay ingot, the mechanism of hydraulic forging and upsetting has been investigated. The results are as follows:-
(1) In general, the inner deformation of ingot is varied according to the width of anvil and its penetration, the deformation of center (Δd) being represented by the following equation
Δd=alogL/D+bh/D+C
where, D=diameter of ingot L=width of anvil h=depth of penetration a.b.c.=constants
(2) In the upsetting, it is found that the inner deformation of ingot has the transition point at the ratio D/H=0·7 where D and H are diameter and height of ingot to be upset respectively.
