How to bend sheet metal without a brake.

How to strengthen thin sheet metal.

Rolling sheet metal edges with wire strengthens the panel in two ways that ordinary sheet metal bending doesn t. Wire edge this is done by putting a small piece of metal wire near the edge of the panel. The metal in the areas where holes and slots are punched gets stretched and become more tensile which gives more structural rigidity to the sheet metal. In addition to strengthening sheet metal panel this method helps in enhancing the finish of the panel edges.

To create bends you can utilize a body hammer dolly or a metal brake. Try rivets or brazing. To setup the punch first drill a pilot hole into a piece of sheet metal with a step drill bit. Preparing to bend sheet metal with a vise.

This also gives a nice finished look to an edge of a panel. Place the die over the draw stud before inserting the stud through the pilot hole. The punch is then. The second is it benefits from the structural integrity that the wire hidden inside gives.

Another way of strengthening the sheet metal is by punching holes and slots. When spot welding for instance each spot weld causes the sheet to expand 360 degrees around the weld. Heat causes metal to expand and warp if you re not careful. One is that by metal being folded over itself it has doubled in thickness.

Part 1 of 3. That is they essentially allow a thin part to behave like a. Beads or flared holes in the sheet metal add material in planes that are aligned with an axis in which the part would otherwise be weak. Welding sheet metal isn t always the ideal way to join sheet especially thin or non ferrous sheet.

Now fold the edge of the metal over the metal wire.
