<p>There is described a new bending and squeezing blade for sheet metal bending machine. The blade (5) comprises a bending tooth (9) provided with a head surface (10) that is suitable to engage the edge of a sheet metal to carry out its bending at 90 DEG and with a foot surface (11) that is suitable to engage the 90 DEG folded edge of the sheet metal to carry out its additional bending at an angle greater than 90 DEG and its possible squeezing on the remaining part of the sheet metal up to an angle substantially equal to 180 DEG . In order to assure the locking of the sheet metal during the operation of squeezing the machine preferably comprises a blank holder (2) provided with a pressing member (14), that can be controlled so as to project from the support foot (13) of the blank holder in order to lock the sheet metal on a fixed counter blade (1). <IMAGE></p> |
