For use in your own punch press.
For dimple-free cutting of tubing, these dies are designed for use in your punch press. Our design was originally patented in 1941, and is in use throughout the U.S.A. and the world. Our two-blade method produces cuts on round tubing with no deformation and minimal burr. A slug, (not chips), is produced, from .06" to .125 " thick depending on the blades used.
Since no chips are produced, and burr is typically 10% of the tube's wall thickness or less, most parts can be cut and are ready for the next operation such as expanding or mandrel bending without deburring or chip removal, drastically slashing handling and final piece part costs.
Die blocks move with cams to completely encircle the tube and prevent OD bulging during cut off, as well as provide a sharp cutting edge for the blades to cut against. A horizontal blade is cammed tangentially across the top of the tube to remove enough wall material for the vertical shear blade to enter and complete the cut without deforming the tube.
This method is best used with mild steel tubing, but can be used on other materials, such as aluminum, stainless, half-hard copper, etc. Vogel Cut Off Dies are designed for offline recutting of tubing, (not "flying" as used when cutting tubes during manufacture on a tube mill).
Square tubing is cut with the horizontal blade mechanism removed, with the tube in the corner-over-corner orientation, also resulting in a dimple-free cut. Die blocks are interchangeable to accept a wide range of shapes and sizes up to maximum capacity of the die. Die blocks and blades can be changed without removing the cut off die from your press and all cutting members are designed to be sharpenable.
All dies are shipped with a (not shown) drip-feed lubrication system and a 24" long end-stop and micro-switch stop assembly which signals your press to cycle. This allows material to be cut as fast as the stock can be fed.
