Sheet Metal Brake Bending

brake is a metalworking machine that allows the bending of sheet metal brake. The cornice brake allows only simple bends and folds, while the box and panorama brake also allows box and panorama shapes to be shaped. It is also known as a bender or brake bender and in the UK as a sheet metal bender or simply as a press brake.


Description


The brake consists of a flat surface on which the material is laid and a clamping bar that lowers and firmly holds the material during bending. This clamping action can be manual, automatic or pedal operated. The machine’s gate-like faceplate is hinged and can be lifted, causing the material, laid out on a straight edge, to flex to follow the slab.


Bends can be at any angle up to a practical limit of about 120 degrees, slightly more in the case of a press brake. If the fold is narrow enough, you can make a tighter fold (eg for a hem) by inserting the fold under the clamp bar and lowering it.


Box and plate brake


In a box brake (also known as a pin brake [1]), the retaining bar includes several removable blocks that can be removed and repositioned to allow bending of limited areas of a sheet metal part or parts already in use. , partially formed pieces.
Once bent, the shape of the box or tray is completed using screws, welding, rivets, or other metal fastening process.


Bar folder


This is a simplified brake, usually much smaller than eaves or box and plate brakes. As a rule, one handle clamps the workpiece and bends it in one motion, but the depth is often much less than a shoulder or a box brake can handle.


brake press


This is a more complex tool that forms predetermined curves by clamping the workpiece between the appropriate punch and die.


dimensions


Brakes come in sizes suitable for lightweight aluminum or brass for small boxes, and manual to industrial size, balanced hydraulic or manual machines suitable for large steel sheets.
