ACCU-BENDTM To protect your Accu-Bend and for optimal performance, please remember the following: .. Use light oil before the first start-up. .. Oil the unit every 50K cycles. .. Clean and inspect the unit every 200K cycles. .. Clean the setscrew and use Loctite® 222 when reinstalling the set screw. .. Don’t distort the saddle pocket and spring hole when machining the saddle. .. Provide backup key to saddle. .. Use the proper method to modify a rocker for more over-bend. .. Provide over-bend back taper allowance in anvil. .. The groove in the anvil for the dart must allow for material...

Shorter lengths or segmenting are possible. Pressure pads can be ordered with Accu- BendTM units. OVERBEND by 3° Bending action continues to form the material around the anvil until desired angle is completed. The anvil should have 5° relief to allow for the 3° overbend.* 3. MATERIAL SPRINGBACK Rocker bends past 90° to counteract material springback, leaving a 90° bent part (±1/2°). 4. START POSITION...

6 www.danly.com .. Use the formula for setting the “K” dimension for a 90° bend using a standard 87° rocker. Proper setting of the rocker centerline in relation to the anvil radius centerline is important for dimensioning the key slots needed to hold the backup key. The "K" dimension for over bend or under bend applications is best determined by doing a CAD layout. Bender Design Information Bender Location The smooth rotary action of a bender requires a greater bend allowance than is typical with a coining or wipe bending operation. The formula for the bend allowance is: Important:...

7 Modified Bends www.danly.com Large Radius .. A bend radius exceeding 3 times part thickness is considered a large radius bend. .. Large radius bends can be accomplished by using a larger size rocker. .. Adding a few extra degrees of over bend is required to compensate for material spring back. .. The rocker inside radius can be specially matched to the part radius. Channel Bend and Hat Bends – Paired Units .. Channel bends can be accomplished in one press stroke by pairing two benders face-to-face. .. In order to use standard benders, the spread or part channel must be greater than 2...

8 www.danly.com Modified Bends (continued) Short Leg .. Short leg bends require a recessed step in the bending lobe of the rocker to accommodate the shorter part height. .. Tonnage requirements will increase as compared to a standard bend. .. The formula to determine the shortest leg possible is: 2.6 x (part thickness) + (part radius). Zee Bend .. A true 90º rocker is used in Zee Bend applications. .. A pressure pad is usually required to make up the difference between the part height and the (I) dimension of the rocker. .. A slight modification to the bending lobe at the time of production...

11 Available Options (continued) www.danly.com Composite Rocker and Insert .. The composite material is a hard, low-friction polymer used as a contact material for stainless or pre-painted steel where slight tool marks are not acceptable. .. Tool marks can be eliminated by using a composite insert in combination with a pressure pad positioned between the part surface and the bending lobe of the rocker. .. Composite inserts are not available in the MB-20 and CMB-20 models. However, we could provide a solid composite rocker as a special. .. A solid composite rocker is used in low production...
