SERVO PUNCHING MAIN TRANSMISSION APPARATUS FOR NUMERICAL CONTROL TURRET PUNCH PRESS

摘要

A servo punching main transmission apparatus for a numerical control turret punch press comprises a crankshaft (1), a connecting rod (2), a punch (3), and a servo motor (4). One end of the crankshaft (1) is mounted on a supporting plate (7) below a bottom plate (6) by means of two self-aligning roller bearings (5). An upper end of the connecting rod (2) is connected to the crankshaft (1) by means of a cylindrical roller bearing (8), and a lower end of the connecting rod (2) is connected to the punch (3) by mean of a hinge pin (9). The other end of the crankshaft (1) is connected to a rotor (11) of the servo motor (4) by means of an expanding sleeve (10). The punch (3) is located inside a guide base (12) below the supporting plate (7). The servo punching main transmission apparatus for the numerical control turret punch press has a simple and compact structure and high transmission efficiency, is convenient to dismount and mount, produces low noise, has small loss and saves energy.
