Abstract

L'invention a pour objet une machine (1) à découper une tôle (2) par cisaillement. La machine (1) est équipée d'un outillage monté sur un bâti (3) et comprenant des jeux de lames (5a, 5b) distants (D1) l'un de l'autre entre lesquels une portion d'une tôle (2a) à découper est prévue de s'étendre. Chacun des jeux de lames (5a, 5b) comprend une lame (6a) et une contre-lame (6b) qui sont montées mobiles l'une par rapport à l'autre sur le bâti (3) entre une position d'ouverture de l'outillage et une position de fermeture de l'outillage dans laquelle la tôle (2) est cisaillée. L'outillage est équipé d'un appareil de retenue (9) de la portion de tôle (2a) contre l'une au moins des contre-lames (6b) des dits jeux de lames (5a, 5b) distants (D1) en une position intermédiaire de l'outillage entre sa position de fermeture et sa position d'ouverture, dans laquelle position intermédiaire de l'outillage les lames (6a) et les contre-lames (6b) de chacun desdits jeux de lames (5a, 5b) distants (D1) sont dégagées l'une de l'autre.The object of the invention is a machine (1) for cutting a sheet (2) by shearing. The machine (1) is equipped with tools mounted on a frame (3) and comprising sets of blades (5a, 5b) spaced apart (D1) from one another, between which a portion of a sheet (2a ) to be cut is planned to expand. Each of the sets of blades (5a, 5b) comprises a blade (6a) and a counter blade (6b) which are mounted movably relative to each other on the frame (3) between an open position of the tool and a closed position of the tool in which the sheet (2) is sheared. The tool is equipped with a device (9) for retaining the portion of sheet metal (2a) against at least one of the counter-blades (6b) of said sets of blades (5a, 5b) distant (D1) in an intermediate position of the tool between its closed position and its open position, in which intermediate position of the tool the blades (6a) and the counter-blades (6b) of each of said sets of blades (5a, 5b) ) distant (D1) are clear of each other.
