Power mechanism for large-tonnage mechanical servo numerical control turret punch press

Abstract

A power mechanism for a large-tonnage mechanical servo numerical control turret punch press relates to improvement of a punch power mechanism for a large-tonnage mechanical servo numerical control turret punch press. Power is increased, and machining precision is ensured to the maximum extent. The power mechanism comprises a servo motor, a lead screw, a sliding nut, an inclined block, a hitting head, a second servo motor and a second lead screw, wherein the sliding nut is arranged on a body and connected with the lead screw through a screw hole, the inclined block and the hitting head are fixedly connected with the sliding nut, the sliding nut is provided with a second screw hole, and the second lead screw is connected with the sliding nut through the second screw hole. The power mechanism uses a main transmission mechanism with the double servo motors for tonnage expansion, on one hand, the punch press can obtain satisfactory punching speed and precision after tonnage expansion, and on the other hand, cost budgeting and spatial size utilization are reasonable.

Description

technical field [0001] The invention relates to the improvement of the punch power mechanism of a large-tonnage mechanical servo numerical control turret punch press. Background technique [0002] At present, when the tonnage of the mechanical servo CNC turret punch press is expanded, it is generally realized by increasing the specification of the servo motor. For high-power servo motors, the increase in output power is disproportionate to the increase in energy consumption on the one hand, showing a steep rise; on the other hand, the greater the power, the greater the inertia of the motor, and when it is applied to a punching machine, the walking accuracy of the punching machine will decrease. . Contents of the invention [0003] Aiming at the above problems, the present invention provides a power mechanism for a large-tonnage mechanical servo numerical control turret punching machine that maximizes machining accuracy while increasing power. [0004] The technical solut...

Problems solved by technology

For high-power servo motors, the increase in output power, on the one hand, is not proportional to the increase in energy consumption, showing a steep rise; on the other hand, the greater the power, the greater the inertia of the motor, and when it is applied to a punching machine, it will lead to a decrease in the walking accuracy of the punching machine
