Adjusting A Sheet Metal Brake

Once again place the sheet metal strip 0 50mm from previous step between bender and bed but this time a little higher from the surface of bed bender.

Adjusting a sheet metal brake.

When hemming and flattening material where double or triple thickness is. If you are having a hard time with the bending action first check to see if a smaller piece of scrap metal can be easily bent. Step 1 check clamping pressure by clamping test strips in the brake approximately 3 or 4 inches away from each end of the brake. Set the clamping pressure so that it is enough to keep the material from slipping during a bend.

Place another piece from the same sheet metal strip 0 50mm vertically onto the bed and between the brake and the first one. It is recommended that this adjustment be made for each thickness of material. There must be adequate area around the brake for free movement of the operator and the handling of large sheets of metal. Check end to end clamp alignment by placing a test strip.

Use test strips of metal approximately 3 inches by 3 inches each of the thickness you will be forming for the following adjustments. Operate the brake and bend some material first before attempting any major adjustment. However if you are using large sheets of sheet metal it may not bend easily. Radius set back refers to the distance between the leading edge of the clamp and the inside edge of the apron.

Do this on both sides of the brake. Check clamping pressure by placing test strips in the brake about 3 or 4 inches away from each end of the brake. For the following adjustment use test strips of metal each approximately 3 inches by 3 inches of the thickness being formed. Adjust the brake so as to be adjoined to metal strip tightly.

A sheet metal brake should bend sheet metal with much more ease than trying to do it by hand.
