Selected according to tube OD(outside diameter) and CLR (center line radius) requirements.
Manufactured of hardened steel and with the fixed clamp jaw welded or screwed into the bending die to obtain best possible transition between the radius and the straight part.
The bending die should be a good fit onto the machined register on the bend head, and must always be securely fastened down.
Selected according to tube OD and match the Bend Die.
Manufactured of hardened steel. Recommended clamping length: three times the tube diameter. For shorter clamping lengths the groove can be fluted to obtain a better grip. In other cases the groove can be milled for bend in bend confi gurations. The clamp die should be adjustable for vertical alignment and parallel contact along its length.
Selected according to tube OD and match the CLR (centre line radius) of the Bend Die.
Manufactured of hardened steel,pressure die length is critical and is determined by bending radius,bending degree and tube OD.Formula:assuming that full 180 degree bends are required:
CLR x 3.14 ÷ 180 x 195 + 3 x tube OD
Example: 1" OD tube x 4" CLR
Selected according to tube OD,tube thickness, bending angle and bending radius.Recommended for small radii and thinner wall thickness.
Manufactured of hardened steel or Ampco Bronze.
When setting up Ball Mandrels it is important to ensure that the leading end of the shank is on Centre Line when bending.The Balls should be forward of this point.
IMPORTANT: Setting of the Mandrel should be carried out with the Mandrel fully forward not retracted.
Selected according to tube OD,bending rdius for use with a ball mandrel. Recommended for small radii and thinner wall thickness.
Manufactured of hardened steel or Ampco Bronze. The purpose of a wiper die is to stop wrinkles from forming on the inside of the bend at the tangent point.
Selected according to tube OD. Collet only used on CNC machine.
Manufactured of hardened steel.
