Description
A bending brake is a metalworking machine that allows the bending of sheet metal. The brake is a Chicago W31 steel box and pan brake. The max material thickness capacity of this machine is 16 gauge mild steel. In a box-and-pan brake (also known as a finger brake), the clamping bar includes several removable blocks, which may be removed and rearranged to permit bending of restricted areas of a piece of sheet metal or of already partially formed pieces. After bending, a box or pan form is then completed by screw, solder, weld, rivet, or other metal fixing process.
Here is an example of this piece of equipment being used.

Demonstration
To demonstrate competency on the Bending brake you will be required to bend a piece of sheet metal to a 90 degree angle.
General Procedure
Bending Steps
- Ensure that your sheet metal is thinner or equivalent to 16-gauge sheet metal, and ensure that it is less than 48" in width.
- If making a bend for a box or a pan, adjust the fingers so that the equivalent width of the fingers is just shorter than your sheet metal.
- Adjust the clamping force and the clamping handle to allow room to insert your work piece.
- Insert your work piece to the line you want to bend, centered in the brake, and clamp your piece securely.
- Pull up on the bending handle of the leaf slowly until your piece is bent to the desired angle, and slowly lower the leaf.
- If the piece does not bend straight, unclamp the handle on the over-bent side and adjust the top leaf.
- Adjust the clamp handle, and remove your piece.
- Put back any fingers if adjusted, and deburr if any rough edges are left.
Safety
Safety First
- Always make sure your hands are out of the way of the fingers and all moving parts.
- Be aware of your surroundings to ensure that you do not bump others with the counterweight.
- If bending a small piece of metal, place it in the center of the brake.
- Do not attempt to bend material thicker than 16 gauge.
- Only use sheet metal with the brake. Don't try to bend round material!
- You may not use the sheet metal machines without safety glasses!! (Should be obvious if you are following the rules of the shop)
Reset the Space
If you removed or adjusted any fingers, put them back where they belong.
