ARC-SNUG ANGULAR UNITS
To notch tubes to fit another tube at a specific angle, for a snug gap-free fit up.Specify notched tube OD & gauge, mating tube OD and angle of intersection. A drainhole may also be notched at the same time, if desired. You can purchase multiple punch & die assemblies and swap them in our Arc-Snug Housings to accomodate additional angles or material sizes.
Arc Snug angular units are designed to produce a "snug" fitting angular or 90° joint on medium and thin walled tubing.
The resulting gap-free notch is suitable for silver soldering, brazing or mig welding. (If stick welding heavy walls, the weld may have to be ground down for appearance purposes. If so, the Arc-Fit Angular units are recommended.)
Each Arc Snug assembly consists of a two station punch and die assembly that requires two strokes to complete the operation. (Note: if two parts are inserted, one part can be produced in each press stroke.)
The first notch is identical to the Arc Fit Angular unit producing a deep notch with an elliptical end.
In the second station the tube rotated upside down, so the first station notch is on the top of the tube. The tube is put in at the required angle of intersection (for example, the unit pictures at left is designed for a 45° notch).
The second station punch gauges on the first notch and carves a radius through the side wall and out the bottom.
Arc-Snug tooling is designed to be sharpenable for long life. Many customers order replacement parts first, then when received, send the old parts in for sharpening. This avoids any downtime and eliminates any expense for rush processing, overnight shipping, etc. Please contact us to obtain replacement part costs. |
