HYDRAULIC SHEET-BENDING PRESSES

The presses are intended for making the parts of the rolled sheets and strips by means of bending.
Bending of a big number of various parts is possible in the universal V-shaped die-stamp supplied as the complete set with the press.
The presses having the big table length (ИП 1426В, ИГ 1428) are provided with the compensation mechanism of table and slider flexure by ensuring the high quality of bending in relation to long sheets having the essential thickness at the rated force.
The electric circuit provides operation of the presses at single travels and in the adjustment mode.
The presses have two-hand and pedal control.
The presses have the manual control.
