Adjusting A Sheet Metal Brake

Use 1 8 in allen wrench to push the pin out of the hole.

Adjusting a sheet metal brake. 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. 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. A sheet metal brake should bend sheet metal with much more ease than trying to do it by hand. Place another piece from the same sheet metal strip 0 50mm vertically onto the bed and between the brake and the first one.

To tighten clamping pressure release the top nut and tighten the bottom nut. Adjust by means of clamping handle adjusting nuts as shown. Set the clamping pressure so that it is enough to keep the material from slipping during a bend. Allow 4 to 6 feet behind the brake 6 to 8 feet in front of the brake and 3 feet on either end of the brake.

Radius set back refers to the distance between the leading edge of the clamp and the inside edge of the apron. Adjust the brake so as to be adjoined to metal strip tightly. When hemming and flattening material where double or triple thickness is. Check clamping pressure by placing test strips in the brake about 3 or 4 inches away from each end of the brake.

There must be adequate area around the brake for free movement of the operator and the handling of large sheets of metal. However if you are using large sheets of sheet metal it may not bend easily. Check end to end clamp alignment by placing a test strip. Step 1 check clamping pressure by clamping test strips in the brake approximately 3 or 4 inches away from each end of the brake.

The 1 8 in size is easy to slip in through the casting and if it is stubborn you can tap it with a hammer to knock it out. It is recommended that this adjustment be made for each thickness of material.
