Abstract

L'invenzione riguarda un dispositivo di supporto in una cesoia per barre di acciaio per il taglio di spezzoni di lunghezze precise da materiale in barre di acciaio e billette, per impiego come spezzoni per la deformazione plastica dal pieno, con una via a rulli motorizzata per l'avanzamento della billetta o simili attraverso il vano di lavoro della cesoia e con un premibarra per il fissaggio della billetta o simili contro un supporto antagonista del premibarra, nonché con un dispositivo di avanzamento eseguito come pinza di avanzamento spostabile assialmente. Per poter meglio adattare, per un taglio ponderalmente preciso, il dispositivo di avanzamento alla conformazione deformata del materiale in barre o billette da tagliare, il sistema di supporto delle pinze, con l'impiego di un dispositivo di avanzamento con una pinza fissa (7) e una pinza mobile (6), avviene mediante barre elastiche di richiamo (23, 24, 25, 26, 28, 29).(Fig. 1).The invention relates to a support device in a shear for steel bars for cutting pieces of precise lengths from material in steel bars and billets, for use as pieces for plastic deformation from solid, with a motorized roller path for the advancement of the billet or the like through the work space of the shears and with a bar holder for fixing the billet or the like against an antagonist support of the bar holder, as well as with a feeding device carried out as an axially movable gripper. In order to better adapt the feeding device to the deformed conformation of the material in bars or billets to be cut, the gripper support system, for a precisely weighted cut, with the use of a feeding device with a fixed gripper (7) and a movable gripper (6), takes place by means of elastic return bars (23, 24, 25, 26, 28, 29). (Fig. 1).
