Embodiment Construction

[0012] As shown in Figure 1, the servo motor 12 installed at the bottom of the fuselage 13 transmits power to the reduction box 7 installed on the fuselage 13 through the pulley 11, the pulley 8 and the belt 9. The coupling 14 of 6 transmits the power to the gear shaft 16, and the gear shaft 16 is coaxially installed on the fuselage through the bearing housings 15 and 17. The gear shaft 16 and the gear 2 are meshed to realize the second stage of deceleration to drive the crankshaft 1 to rotate. The crankshaft drives the slider to move up and down to complete the stamping function. The end of the crankshaft 1 is coaxially fixed to the encoder output shaft 3, which is connected with the resolver 5 installed in the resolver seat 4 on the fuselage, and the resolver 5 inputs the rotation signal of the crankshaft to the encoder 18 through the signal line 19, After being processed by the encoder 18, the signal is input to the servo motor 12 to control the start and stop of the servo ...

Abstract

A power transmitting and braking apparatus for a press driven directly by servo motor is disclosed. The gear and the slide block of crankshaft are driven by a servo motor via speed reducer and gear axle. The encoding output axle fixed to external end of crankshaft is synchronous with a rotary transformer. The rotation speed signal of crankshaft is sent to a programming device by said rotary transformer, where it is processed and then output to servo motor for controlling the servo motor. Its braking unit has an improved structure consisting of braking wheel, spring, braking cylinder, crank-connecting rod mechanism and drum brake, and features high response speed and low noise.

Description

technical field [0001] The invention relates to a press, in particular to a power transmission and braking device for a servo motor directly driving the press. Background technique [0002] At present, the working power motor of ordinary crankshaft presses has been running continuously after starting up. A huge flywheel is installed outside the fuselage. The reduction box drives the flywheel to rotate. The block moves up and down to realize the stamping function. Idling of the motor and flywheel produces a large amount of reactive power consumption. The brake system of the currently used press adopts a pneumatic brake, which is composed of electromagnetic clutches, friction plates, hydraulic valves and other components. . Contents of the invention [0003] The purpose of the present invention is to provide a power transmission and braking device for a press directly driven by a servo motor, which eliminates the large...
