ABSTRACz Nine different analytical formulas for calculating the stamping force
~in metal itamping were compared with experimental results for the configuration
shown in 1'g. 1 on the Enclosure. Equations for the nine formulas are presented
and their derivati,=.c and major assumptions are briefly discussed. Three of the
formulas are semi-empiricalt three use integration of approximate equations of
equilibrium and plaelvicityp two use variational principles of mechanicsp and one-
uses the method of obn-racteriatica. The results obtained with these formulas were
compared witu experiaental results for D./N - 3.7 - 69.0. It was found that two
of the formulas gave significantly better r6sults than the rest; one derived by
Y iational mothodog the other by the method of characteristics* The latter was
derived by L. A. Shjfma (Oanovy* reacLeta. protsessov shtanpovki i pressovanlya.

TEXT.- The "closed piercing, i.e., foraing "he punch into a billet held
in a zhell (or die), Is widely used for prcduction of cupped p Z7,

of ttin-walled

Fir7s_tstage -whe-n metal fills the space, the sezond stage in which metal is
forced out from under the punch and flows upward, plastic deformation under
the. panch remaining at a certain depth, and the third stage, when all metal
under the punch tak~~.s part in plastic deformation. The calculation of efforts
ni~cessary for the operation is of practical importance. The calculation method
had been published previously (in Refs. 5,6, etc.). This article gives a prac-
tical oalculation of a problem with analysis of the second and third stage of
the process. A fornrala is derived (27) for determining the P value, i.e.,

TITLE: On the use of high-speed computers in developing die-forgLng

PIMIODICAL: Kuznechno-shtampovochnoye proizvodstvo, no. 2, 1963, 10 -13
TIM: The authors are of the opinion that for solving the problems con-
nected with the design particulars of a given component, e.:g.-dimensions,
material, surface finish etc., high-speed computers can be used. Besides in-
creasing the productivity, they wouldeliminate any subjective solution of" tech-
nological problems. Since the most simple and widespread group of forgings are
axially symmetric ones, i.e., forgings of the body-of-revolution type, this
type of forgings'Would be the first whose tec,mology could be developed by means
of high-speed computers. The authors give a detailed description of.a universal
program which is being developed at present by a team of scientists of the Sec-
tion "Metal Working" or -tLe Urallskiy politekhnicheskiy institut imeni S. M.

TITLE: Theoretical Investigations in Open and Closed Dies for

PERIODICAL: Nauchnyye doklady vysshey shkoly. Metallurglya, 1958,

ABSTRACT: The stages of annular swage blocks inNopen and closed dies
were inve~;tigated. In punching in open dies the filling
in of "~,e metal into the -.avi,ties of the dies as well as the
flow of the metal are determined by the position of the
critical surface. In stamping in closed dies an unequal
flow of the metal in the open zone is observed. This in-
fluence is explained by the different direction of the
internal friction forces in those zones. The rules governing
the flow of the metals in various stages of the stamping
of annular swage blocks were determined. A simple formula
for any moment of the depression, in the second stage
Card 1/2 of stamping was found (7). By knowing the position of the

critical surface for any moment of the depression in
the second stage of stamping the height of the metal
in cavity may be calculated at any single moment. Taking
into account the rules governing the flow of the metal
in the various cavities as well as the velocity factors
in stamping an efficient construction of the dies may be
reached. There are 5 figures and 2 reftorences, 2 of which are
Soviet.

TEXT: In order to develop methods of detdrm'ining the force in pressure
working of metals, the authors attempted the derivation of a formula to calcu-

Force and pressure are calculated -ith the use of a rough, approximate metal flow
diagram( Fig 1) where the container is divided into 3 sections, the velocity
field is.Xirtematically possible, and value "all.is the depth of deformation
spread. The following simplified formula for the necessary force in pressing
rods is derived:
