Used press brake operation

Precise shapes using a bending punch and bending die

A press brake is used to form bits of sheet metal through bending. Through the use of a bending punch and a bending die, this press transforms the workpiece into machine components, casings or containers. These machines can also be called bending machines or brake presses. Through the lowering of the punch, the sheet metal takes on the form of the casting that it is pressed into.

Complex forms can be incorporated onto the sheet metal (without having to switch work tools) by repositioning the workpiece and lowering the punch each time it is in a new position. The process of air bending is used most often. It can be used to incorporate various angles onto the workpiece without having to switch the work tools. Coining is used to gain very precise results, as it only used to bend one specific angle. Three-point bending is even more precise, and depending on the set-up, the switching of work tools for different angles during this process is not always necessary. Creating a fold is done in two stages, where air bending is first used followed by a pressing process.

More power also requires higher safety levels

The rolling of sheet metal was first discovered at the end of the 17th century through the discovery of effecting rolling processes. Bending machines for sheet metal processing were manually operated using a very high expenditure of energy. The work was made easier, but also more risky, through development of the automatic version of this machine. Machines built before 2002 were operated using a two handed switch. This switch was designed for safety, as it ensured that both hands of the operator were out of the way during the closing of the press. However, the disadvantage of this was that the sheet metal construction could not be held or guided since both hands of the operator were occupied. In addition to the holding arms, modern press brakes also have an optical surveillance system (usually a laser) on the underside of the press. If something comes in the way of the laser, an emergency stop kicks in.

Applications

Used press brake workplace
Press brakes are available in a variety of forms, corresponding to the workpieces that they will process. These machines are used for furniture, shelves and doors made out of sheet metal, as well as the manufacturing of containers for electric machines and covers for machines. Press brakes can also be used for the furnishing of kitchens and restaurants as well as medical facilities. Other uses include the building of roofs and facades, the production of partitioning walls and the manufacturing of lifts and escalators.

Many suppliers

Used press brakes from leading suppliers at low prices are available. Surplex provides machines from AMADA, LUTHER and the Hungarian machine manufacturer DIGEP.
