Tooling for Portable Machines

The Cleveland Punch & Die Company would like to welcome you back!! We hope you had a very safe and happy holiday!


Just recently, The Cleveland Punch & Die Company has experienced an abundance of incoming calls with customers inquiring about our stock tooling for portable machines. Cleveland Punch & Die does have stock punches and dies for many of the portable machines and non-stock tooling can be shipped in as little as 24 hours. We have provided you with a few catalog pages below to get you started!

Center Punches

Center Punches

A center punch is a hand-held punch which consists of a steel rod that tapers down into a point which will be hammered into the material, indicating where the hole is to be punched or drilled. Center punches are typically used in several different applications. Some of our customers use the center punches to mark the material that they wish to punch. These marks act as targets when lining up the punch and die. Some customers also use the center punches to make a dimple in their material to serve as a guide for drilling. In this case, most of the drill bits tend to have a mind of their own unless they have a recess to start in. Center punches are known throughout the industry for their reliability and durability.

Transfer Punches

A transfer punch is a hand-held punch that consists of a steel rod that tapers down to a particular outer diameter size and has a crowned center point. It is used to tightly fit the tolerances of an existing hole in a template and when hit with a hammer, it transfers the center of that hole to another piece of material. It is commonly used to precisely set locations for threaded holes, (created by drilling and tapping), to bolt an object to a surface.

The Cleveland Punch & Die Company carries many center and transfer punches in stock! For additional information please contact one of our experienced “Green Team” members at (888)451-4342 from 7am-6pm Monday through Friday.

Tonnage

Does my machine have enough tonnage to be able to punch the hole that I need to punch?

Let’s say for instance, you have a 50 ton machine and you want to punch a 5/8” round hole through 1/2” A-36 mild steel. Do you have enough tonnage? Using the formula in the chart: LTS/2000 we calculate

                           1.9635 x .500 x 60,000 =29.45 tons

                                        2,000

This means that 29.45 tons of pressure is required to punch a 5/8” hole in 1/2” material. Your machine is 50 tons, so you will have enough tonnage to punch that hole.

For punching materials with a different shear strength than 60,000 PSI as listed in the tonnage charts, it is necessary to use a multiplier for calculating the proper amount of force required to punch the hole.

EXAMPLE: From our previous example, to punch a 5/8” round hole through ½” A-36 mild steel, the force required is 29.45 tons. If this material is stainless steel, with a shear strength of 70,000 PSI, (according to the chart below), the correct multiplier to use is 1.17 therefore;

29.45 tons x 1.17 = 34.46 tons, actual force required.

If you have any questions please contact our "Green Team" for assistance. We can be reached at 888-451-4342 from 7am to 6pm EST.

Punch and Die Set of The Week!

Every week we have exciting things happening at The Cleveland Punch & Die Company! This week we completed manufacturing a Half Lattice and Punch Set. This punch and die set shears a radius on a piece of flat bar and punches a hole at the same time. It’s as easy as 1, 2, 3! First, load the punch and die into your machine. Second, place the material on top of the die, then simply cycle the machine. This application has a bolt-on mechanical stripper/back gauge which acts as a guide for the material while also assisting in stripping the punch out of the die, making this application very user friendly.

This punch and die set is commonly used in the manufacturing process of handles or brackets. The customer using this particular set is shearing and punching both ends of a piece of 1-3/16” wide flat bar. The customer will then use their press brake attachment on their ironworker to bend the material into a handle or bracket.

The Cleveland Punch & Die Company is ready and eager to help you with all your special projects! We love coming up with creative solutions for all your punching needs. If you have a punching application you want to do, but are not sure how or if it can be accomplished, give us a call and we will use our 130 years of experience to design a punch and die set that will work best for you.

Remember to Check Your Diagonals!

You must check the diagonal of your square sizes to ensure that the punches will pass through the bore of your coupling nut without interference. The diagonal of a square can be determined by multiplying the size of the square by 1.414, or refer to our diagonal table.

There may also be occasions when it is necessary to check the diagonal of your hexagon size to ensure that the punch will pass through the bore of your coupling nut without interference. The diagonal of a hexagon can be determined by multiplying the size of the hex by 1.1547, or refer to the hexagon diagonal table below.

You must also check the diagonal of your rectangle punches. The diagonal of a rectangle can be determined by the Pythagorean Theorem: A²+B ²=C². The "A" dimension and "B" dimension are the two sizes of the rectangle and "C" equals the diagonal of the rectangle.

You could also refer to the rectangle diagonal table below.

 
Example:  You need to punch 13/16” square holes.  Suppose your  machine requires that you use F-16 punches and your coupling nut is a CN-16.  You first need to turn to the coupling nut pages in your Cleveland Punch & Die Core Catalog.  On the left side of the page, locate the CN-16 coupling nut.  Run your finger to the right to determine the bore size.  The bore size measures 1.070.

   

Using the diagonal formula: 13/16” x 1.414 = 1.148. This diagonal exceeds the 1.070 bore of the coupling nut which means that the corners of the square will not pass through the nut. In this case, there are two options that we have to proceed with this application. You can file out the corners of your coupling nut to allow the 13/16 square to pass through or we can make you a coupling nut with a special square bore. This can be done for rectangle and hexagons as well.
