A cup of 5o mm diameter and 20 mm height is to be
produced by drawing from a 1.5 mm thick sheet metal.
What is the maximum drawing force ? If ultimate tensile
strength of metal is 650 MPa.
Circles of a metal are being punched that will be later stamped into coins. The metal has a shear strength of 32,575 psi. The sheets are 2.1 mm thick. The coin blanks are to be 16.5 mm in diameter. If sheet of metal is expected to produce 50 coin blanks, how much force is required to punch the sheets?
A compound die will be used to blank and
punch a large washer out of 6061ST
aluminum alloy sheet stock 3.50 mm
thick. The outside diameter of the washer
is 50.0 mm and the inside diameter is
15.0 mm. if The aluminum sheet metal
has a tensile strength = 310 MPa, a
strength coefficient of 350 MPa, and a
strain-hardening exponent of 0.12. (a)
Assume that blanking and punching occur
simultaneously. (b) Assume the punches
are staggered so that punching occurs
first, then blanking. Determine (1) the
punch and die sizes for the blanking
operation, and (2) the punch and die sizes
for the punching operation.(3) the
minimum tonnage press to perform the
blanking and punching operation
