The fundamental feature of the development is determined by the structural combination of the press brake and shears for cutting sheet material into a single machine, the combined working body of which receives movement from the same drive and performs the bending operation when moving up, and the cutting operation when moving down without additional readjustment.<br>
In the universal V-shaped die supplied with the press it is possible to bend parts of various profiles.
In special dies, available for a fee, it’s possible to perform bending complex parts in one step, radius bending, hole punching and stamping.
The drive of the working body is hydraulic, through a lever which ensures the synchronous operation of the hydraulic cylinders and eliminates distortions; the hydraulic station is built-in, which reduces the vibration and acoustic load on the operator and the environment, and also ensures the technical aesthetics of the entire structure.
Separate for bending and for cutting backgauges make it possible to produce parts of the required accuracy degree.
The backgauges and slide adjustment mechanism are driven by electric motors.
The amount of adjustment of the stops is controlled by a D-Range Optimizer (DRO).
The press INP4.40 ensures that all safety and ergonomic requirements for forging and pressing equipment are met.
