Abstract: The invention relates to a method and apparatus for adjusting the width of the bending jaws in a bending machine. The total width (L) of the bending jaws is formed by using jaw parts and edge pieces in the following manner:a first set (R.sub.1) is elected to form a group of jaw parts of different widths for so-called fine adjustment, one at a time (R.sub.1n) being at the operational point (T) of the bending jaws, a second set (R.sub.2) is elected to form a group of jaw parts with identical width and to be separate from the edge pieces (RK.sub.1, RK.sub.2) for so-called coarse adjustment, wherein the width of the bending jaws required at a time is elected according to the equation L=R.sub.1n +N * R.sub.2i +C, wherein L=the width of the bending jaws, R.sub.1n =the width of the jaw part (n=0 . . . M) elected from the first set (R.sub.1), N=the width of the jaw parts of the second set (R.sub.2), i.e. a constant, R.sub.2i =the number (i=0 . . . k) of jaw parts of the second set (R.sub.2) at the operational point (T) of the bending jaws, and C=a constant, comprising the parts with a constant width included in the total width of the bending jaws, i.e. preferably at least the total width (C.sub.R) of the edge pieces (RK.sub.1, RK.sub.2) and the total width (C.sub.L) of the locking parts (LO) between the first and second sets.

Abstract: Machine used for folding, profiling and cutting metal sheets includes a fixed support structure (1) holding a lower presser element (3), on which the sheet (4) rests, and an associated upper mobile presser element (5). Together, the presser elements (3, 5) keep the sheet (4) pressed in a proper horizontal plane. The machine further includes a mobile structure (7) having a C-shaped cross section which defines a channel (2) of longitudinal orientation. This C-shaped structure holds a pair of holding blades (8-9) which perform the folding of the sheet (4) when the same C-shaped structure is raised and lowered or made to advance or withdraw with respect to the sheet (4). In the interior of the channel (2) at least one removable tool holding group (10-11) is situated. This permits repositioning of the tool holding group along the longitudinal course of the channel (2). The tools used are provided for the execution of profiling and/or cutting operations on the sheet (4) held in position by the upper (5) and lower (3) presser elements.

Abstract: A bending machine designed to bend and shape sheet metal comprises a blade-holder unit (10) with a “C” shaped cross-section, mobile along two mutually orthogonal directions with respect to a fixed bed, and on which one or more bending blades are fixed. This machine comprises a kinematic system for driving the operating units, in which servomotors (15, 21, 22) and epicyclical reduction gears are used for the movement of the blade-holder unit (10). Moreover, the blade-holder unit (10) of the bending machine uses an articulated mechanism consisting of two mechanical units (13, 14) which form a closed kinematic chain with five members connected by five kinematic turning pairs.
