Sep 1, 2017 · Previous columns have addressed draw-reduction ratios, forming speeds, and punch-and-die radii. Other data, such as die clearances and blankholder pressure, can be better understood by examining the anatomy of a deep-drawn cup.

Sep 5, 2017 · Let’s explore the step-by-step process of deep drawing an axial symmetrical round cup out of 0.062-inch material. The cup is 2 in. in diameter and 8 in. tall with no radius on top. To process a deep-drawn part, you must first know three basic things: the metal thickness, the metal type, and the blank size.

PUNCH LENGTH AND CUP DEPTH Using rotary tablet press punches of consistent length is critical because their length directly relates to the uniformity of the hardness, weight, and thickness of compressed tablets. If you don’t understand how length and cup depth affect tablet quality, you may attribute tablet defects to the wrong source.

punch press, machine that changes the size or shape of a piece of material, usually sheet metal, by applying pressure to a die in which the workpiece is held. The form and construction of the die determine the shape produced on the workpiece.

In this Exercise we analyze a manufacturing process which stamps a steel cup. This example problem illustrates the use of multiple steps to model a complicated manufacturing procedure. A flat sheet of steel is loosely secured over a die and plastically deformed with a punch to form a …

Jun 20, 2008 · Experimental and numerical cup thickness in different directions for a hydromechanical deep drawn cup with chamfered punch geometry. Material: DC04 ( D 0 = 280 mm, t 0 = 0.8 mm), draw depth: 170 mm, drawing ratio: β …

Oct 6, 2016 · This study investigated the copper cylindrical cup multistage deep drawing process by using a microridge punch to reduce the number of stages. During the deep drawing process, the microridges are pressed into the blanks to generate the drawing force.

As shown in Figure 1, the basic elements of deep drawing are punch, blank holder or stripper, die and blank. When the blank holder force is low, the compressive stress can exceed the...

Knowing the importance of and how to calculate critical punch measurements is key to consistent tablets manufacturing. Learn more about the importance of working length, cup depth and overall length, and how to use these measurements in this FREE whitepaper.

Cup punches are strong, solid steel punches that use a spherical shape to cut, compress and remove the slug. They are often used in place of a tube with spring combination and offer accurate concentricity from the cut to base. Standard cup punch sizes range from 1/32 to 31/64.
