Abstract

Secondo l'invenzione si realizza una cesoia comprendente un telaio (2), provvisto di un piano (3) di appoggio della lamiera (4) da tranciare, al quale sono applicati almeno una matrice (7) ed almeno una coppia di lame inferiori (6) disposte ad angolo, ognuna applicata ad un portalama inferiore (12) e di un montante (5), insistente sul piano di appoggio (3), al quale sono applicate una testa (10) provvista di almeno un punzone (9) ed almeno una coppia di lame inferiori (8), ognuna applicata ad un portalama superiore (19), disposte ad angolo. L'angolo fra dette lame superiori (8) e l'angolo fra dette lame inferiori (6) è reso concordemente ed ugualmente variabile tramite mezzi noti di movimentazione e di guida dei portalama (13, 12).According to the invention, a shears comprising a frame (2), provided with a plane (3) for supporting the sheet metal (4) to be cut, to which at least one die (7) and at least a pair of lower blades are applied ( 6) arranged at an angle, each applied to a lower blade holder (12) and to an upright (5), insistent on the support surface (3), to which are applied a head (10) provided with at least one punch (9) and at least a pair of lower blades (8), each applied to an upper blade holder (19), arranged at an angle. The angle between said upper blades (8) and the angle between said lower blades (6) is made in accordance with and equally variable by known means for moving and guiding the blade holders (13, 12).
