COMBINED HYDRAULIC PRESS FOR SHEET MATERIAL CUTTING AND BENDING model ИНП4.40

A principal peculiarity of the development is defined by means of the structural union of the sheet bending press and the shears for list material cutting, comprising the single machine, whereof the combined operating body is moved by the same actuator, and it performs the bending operation while moving upwards, and the cutting operation while moving downwards, without additional readjustment.
Bending of complex parts by one passage, bending by radius, hole punching and die stamping can be fulfilled in special press tools to be supplied for individual payment.
The working body actuator is hydraulic, via the lever providing the synchronous operation of hydraulic cylinders and excluding the misalignment.
Rear rests, which are different for cutting and bending make it possible to manufacture the parts of the required precision.
Back support drive and slide adjusting device are managed by the electric motors.
The magnitude of adjustment of the rests is controlled on devices of digital indication (DDU).
