The mechanism is simple in structure. By means of the auxiliary bearing mechanisms (4) additionally provided under left, right and rear ends of the lower mold frame (2), a uniform gap between the lower mold frame (2) and the base (1) is ensured, and thus uniformity of backlash and a smooth motion are ensured; and a servo gear motor (25) is mounted in a sliding groove of a connecting plate (26) on a rack, the pinion (6) is mounted on an output shaft of the servo gear motor (25) and can move together with the servo gear motor (25), thus facilitating a change in a centre-to-centre distance between the pinion (6) and a large gearwheel (5).
A guide pillar-guide bushing mechanism for a pendulum shear die comprises a guide base (2) arranged at the two ends of a lower die shoe (1), wherein a stepped hole is formed at the upper end inside the guide seat, a wedge type upper guide sleeve mechanism (4) is arranged in the stepped hole, a lower guide sleeve (5) is arranged at the lower end of the guide seat, an upper counterbored hole and a lower counterbored hole which extend along the axial direction are formed at the upper end and the lower end of a guide pillar (3), the upper counterbored hole and the lower counterbored hole are connected by virtue of a double-thread screw (8), a disc spring (9) sheathing the double-thread screw is arranged in the upper counterbored hole, a spring (10) sheathing the double-thread screw is arranged in the lower counterbored hole, an end shield (6) is arranged at the lower end of the guide seat, an oil drain channel (16) is formed in the side wall of the end shield and is connected with the lower counterbored hole, an oil back-leakage channel (17) is axially formed in the side wall at the lower end of the guide seat, an annular space is defined by the inner wall of the guide seat and the outer wall of the guide pillar, and the upper end of the oil return channel is communicated with the annular space through a spill port (18). The guide pillar-guide bushing mechanism is simple in structure, good in wear resistance, good in lubricity and low in friction coefficient; and by eliminating the clearance between the guide pillar and the guide bushing, guide accuracy is improved, and the service life is prolonged.
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.
A numerical control right-angled clipper comprises a machine body (1) and an upper slide rest (2). Above the upper slide rest (2), at least four driving mechanisms that drive the upper slide rest (2) to move up and down are arranged. A resulting moment of longitudinal component forces imposed by each driving mechanism on the upper slide rest (2) is zero. The driving mechanisms of the numerical control right-angled clipper are arranged with four points be symmetric. In a clipping process, a side-direction force is not completely borne by a ball linear guideway at a side of the upper slide rest, making the upper slide rest run stably. A drive structure adopts rolling friction, reducing energy loss.
