Punching Angle


Punching holes in angle can be quite challenging if the die block on your machine is nonadjustable. Luckily for you, we have the solution!

Offset punches with matching offset dies solve this problem and allow you to punch closer to the inside leg of angle iron. The punch is machined offset based on the body diameter of the punch and size of the hole. For example, if you're using a F-16 punch (1-1/16 body) and punching a 1/2" offset hole, the offset will be .281". (See drawing). The die will be offset .281" as well to match the punch. The tooling is inserted in the machine the same as a standard punch and die.

We manufacture offset punches and dies for every ironworker to make your job easier. Have questions? Contact us anytime to see how offset punches and dies can help your production! We can be reached at sales@clevelandpunch.com or by phone at

Lancing Punch

video
In this application, the customer required an elongated D lancing punch. Lancing is defined as a process where material is sheared and bent to make tabs, vents and louvers. During the process, there's no material removed, it is formed into the shape required. The customer requested a 13/32" x 1-19/32" tab to be generated. We machined a blend radius on the rectangle end of the die to prevent the material from shearing. The angle of the tab varies depending on the stroke of the punch. 

Check out the pictures and video to see how the tooling and finished product were used!

Custom Gum Drop Punch

Our customer needed to manufacture gum drop shaped tabs with ½” holes using their Marvel MSIW60D ironworker. Our engineering team determined a two-step operation would be necessary to produce these tabs.

The first operation included manufacturing gum drop shaped tooling to fit the oversize attachment. The punch was machined with a flat face and we used .028” clearance to ensure each tab would be free of any distortions. Lastly, it was critical to machine a 1/4“x1/8” keyway on the punch and whistle notches on the die to provide proper alignment during the punching process.

To begin the second operation, we replaced the oversize attachment with the standard attachment for punching the ½” round holes. This is an easy switch and tooling is more cost effective. We designed a die with 3 alignment pins to guarantee the hole would be punched in the same position on each tab.

The customer will weld these onto their product and utilize the round holes for bolts.

Ripping Punch

The requirement to punch oblong/slotted holes beyond the capacity of an ironworker is a common occurrence and we have a solution!

Ripping punches allow an ironworker to punch holes of any length with a continued cycle. First, punch a round hole in the same size as the width of your desired oblong hole. Next, insert the guide of the ripping punch through the pre-punched hole and begin cycling the machine while feeding the material into the guide. Continue this process until you achieve the length of oblong/slot desired.
When ordering please provide the following information: figure number of punch and die, material thickness and dimensions indicated in the diagram below.


**SAFETY WARNING** Do not punch with the guide!

Example:


  • Machine: Peddinghaus 1100G
  • Punch: F-20
  • Die: F-59
  • ‘A’ Dimension: 13/16”
  • ‘L’ Dimension: 1-1/4”
  • Material Thickness: 3/8” Mild Steel
