Punching Force Calculation Formula. If you punch round holes or square holes, or some other forms of holes through a given thickness of metal, you just want to know the force required to punch a hole in steel. You can calculate the punching tonnage been required with the help of the following punching force calculation formula (blanking force formula):
deflection of a standard press will be approx. 1.5 times more than the bed deflection. As shown below, the E2H has been designed with extremely low deflection providing the ability to run tighter punch-to-die clearance, as well as the flexibility to run small, full tonnage dies on a large press while maintaining part quality and die life.

Jan 08, 2015· Assume about 8 ton per square inch to forge mild steel and triple that for carbon stainless. Thinner metal needs more tonnage as the dies bleed the heat. You can use up a lot of tonnage if you just stick the material under the die and go. Creative die design can overcome many issue with a hyd press, but in the end I prefer big and fast.

This information is valuable when determining which of the Conway Press C-Series hydraulic presses will best suit your needs. Additional information regarding the differences about the C-Series models is available on the C-Series product page. Please let us know if we can help you use this calculator or in selecting a Conway Hydraulic Press.
Press brake tonnage can be calculated using material type, the vee dies opening, bend length and material thickness. To give you an idea of scope, a 30-ton press is fairly small and may be good for starting, while a 600-ton hydraulic CNC press brake can handle steel so large it requires fork-lift loading.
Nov 21, 2002· Negative tonnage, often referred to as reverse or snap-through tonnage, is the undesirable result of cutting operations. Basically, when a punch breaks through the metal during a cutting or piercing operation, a negative force results that pulls down both the cutting punch and the top portion of the press assembly.
Working With Punch Press Tonnage Last month, we wrote an article on tonnage and provided some ... Material type, material thickness, punch geometry, machine type, and machine speed all play a role in determining what the true "maximum tonnage" ... Too big or too small of a clearance affects the punching tonnage, stripping pressure and ...
Jun 30, 2017· In reality, however, most progressive dies will have spring pads, lifters, or stripper springs that get compressed during the stamping process, so your press tonnage will have to be adjusted to include them. A good way to determine the exact press tonnage required is to cycle the tool in the press with no material and measure the tonnage.

Rated press capacity is the tonnage pressure the slide can safely exert at the bottom of the stroke. Mechanical press capacity is typically based on the bending capacity of the main shaft (crank, toggle, or eccentric shaft). It is important to know and understand 1.) Tonnage Curve based on rating point ABDC / above bottom dead center and 2.)
