Urethane V-Pads for Scratch-Free Forming

The most economical urethane die-inserts, for forming Scratch-free V-bends and small radius bends on press brakes.
V-Pads are triangular shaped die inserts designed to fit in standard steel V-dies.
Stock sizes are for ½", 1" and 2" opening V-dies.
Lengths: Up to 8'.

The most economical press brake forming method, for polished stainless steel, Aluminum and Pre-finished surfaces (Painted, vinyl-coated surfaces). Triangular shaped pads are used on steel V-dies. Bending starts at the line of contact of Punch and sheet metal, and tangentially moves outwards. There is no sliding or dragging of sheet metal, as in steel dies.

Bends precisely conform to the sharpness or radius and angle of the punch, with minimum or no spring back. Forming stars from the point of contact, with no blank slippage. Forming of blanks with cu-outs or uneven ends is possible. On very long bends with close tolerances, as long as the punch is precise, accurate bends can be made. (We have customers that have used the V-pads for making bend 16' long with good results). Even on older machines with uneven or non-parallel beds and rams, precise bends are possible without shimming.

Precise radii can be bent with the same V-pad, without the need of matching expensive die sets. The inside radius of a given bend can be machined on the punch and the V-pad functions s a universal die.

"Short Bend Legs" (bend legs of three to four times metal thickness) are possible.

Existing steel punches, and dies (1/2", 1", 2", openings, 85 degrees or 90 degrees can be used. Set up is simple. Just place the V-Pads in the corresponding size to steel V-dies, and without the need for expensive die alignment or shimming, you are set to go.

For bends longer than the V-pad length, just butt them end to end, making sure that the ends are square and prevent lateral movements by using double faced tape (P.P.C part no. P. T. -2000). Depth of punch penetration, into the V-pad should be as least as possible to make a given bend, for maximizing the pad life.
Never penetrate more than half the pad height. Width of punch penetration, into the V-pad should be limited to half the pad width.
Gauge of Metal
For press brake forming: Maximum recommended gauges for M.S. and Aluminum.
½" pad: 18 GA., 1" Pad: -16 GA, 2" Pad:-14 GA.
For Stainless Steel: Use the next lower Gauge.
Tonnage
(Approximate tons per foot length for V-bends): 20 GA. - 4tons, 16 GA.- 6tons, 14 GA.- 9 tons.
Lengths
PV-200=4' (48" ), PV-200H=4' (48" );
PV050& PV-100=96".

For longer lengths, butt them end to end and use double face tape under the pad.
