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): results for this questionWhat is clearance in punching?What is clearance in punching?Determine what size die you need for your punching application.Clearance is the amount of extra space required in the hole of the die to allow the punch to pass through to punch a hole in the material.Clearance is determined by the type and thickness of the material being punched.Die Clearance Calculator Cleveland Steel Tool results for this questionWhat is hole punching?What is hole punching?Metal Supermarkets provides hole punching services in a variety of metal types and shapes.Punched holes are typically created using a punch press or ironworker and are frequently used in baseplates,racking and steel structures.Cost effectiveness.Hole punching is fairly inexpensive compared to other fabrication methods.Variety.Hole Punching Metal Supermarkets

But what if youre processing carbon steel between 0.25 and 0.375 inch thick? You could call this thickness range thin plate. Servo-electric machines usually are rated up to only about 33 tons of punching force.When youre punching 0.375 in.,you move beyond the capacities of the electric servo punchHole Punching Metal SupermarketsWe provide hole punching services in sheet metal or thin bar stock.Metal Supermarkets provides hole punching services in a variety of metal types and shapes.Punched holes are typically created using a punch press or ironworker and are frequently used in baseplates,racking and steel structures.The benefits of hole punching include:

The formula is Perimeter times thickness times shear.For round holes in steel this is Diameter * PI * 30.Thirty tons being the approximate shear strength of mild steel plus an allowance for friction.Tons are used to aid in press selection and rating.The practical limit for depth of punchingPunching metals : metal fabricating processThe punching process forces a steel punch,made of hardened steel,into and through a workpiece.The punch diameter determines the size of the hole created in the workpiece.The illustration that follows provides a two-dimensional look at a typical punching process.Sheet Metal Punching Company Dallas,TX Metal Punching Sheet Metal Punching Defined.Sheet metal punching in metal fabrication is the process of using a machine to press a shape through a sheet of metal and into a die to create the desired shape in the metal.This is most commonly done by use of a turret,a computer numerical controlled machine that houses tools and their corresponding dies in a revolving indexed turret.
Another way is to use a punch with a hole drilled in the center and a spring-loaded steel or urethane pin inserted into it.When ejector pins fail,you can try pulling them out to create a kind of ported punch; the empty hole by itself can help break some suction
