SAFETY

  • Always wear approved safety glasses or face shield while operating the equipment.
  • Before operating equipment, remove tie, rings, watches and other jewelry, and roll sleeves up past the elbows. Remove all loose clothing and confine long hair.
  • Non-slip footwear or anti-skid floor strips are recommended.
  • Closed toe shoes are required when working in a shop area.
  • Wear gloves while operating the equipment.

PROCEDURE

Di-Acro Manual Benders are for bending wire, solid stock, tubing, flat stock, etc. and to accurately form and duplicate simple, compound, and reverse bends. The operator is also able to quickly change over tooling from one bending operation to another.

Bender is for the heavier operations for materials as heavy as 1/2” round steel bar and 3/4” diameter steel tubing. Radius Capacity is 9”.

Detailed illustrations below show procedure for cold forming a standard bend in solid material.

Review the ART OF BENDING to gain insight into the machine’s bending versatility for the following types of bends:

Quick Lok

1. Remove nose and replace with Forming Roller

2. Mount grooved Radius Collar as shown below

3. Set Quik-Lok to match up with flat side of Radius

4. Locate two 3/8” diameter bolts in Quik-Lok base and tighten.

5. Make sure handle locks in forward position.

TROUBLESHOOTING

  • A Forming Nose is to set the exact material thickness and this adjustment is necessary when bending centered eyes as the Forming Nose must be in close contact with the material when the eye centering bend.
  • Forming Nose must be grooved to fit material.
  • Lubricating the forming Nose also reduces marking.
  • When the material to be formed is sufficiently rigid and the required bend is somewhat less than 360°, it is often desirable to leave considerable clearance between the material and the Forming Nose, as this reduces the bending effort.
  • Under these conditions it is also possible to use a Forming Roller and its use is especially recommended when it is desirably to reduce work marking.
  • Flattening on the inside of a bend, which occurs when round materials are formed to a small radius, can be eliminated by grooving the Radius Pin or Collar to exactly fit the Bar.
  • If the bend is in excess of 180°, the Grooved Pin or Collar must be split horizontally so the formed material can be removed.
