Abstract
The invention relates to a structure of a servo drive press. The structure comprises alternating current servo motors and transmission mechanisms, which are symmetrically arranged, wherein each transmission mechanism can comprise a belt wheel, a screw rod and a toggle rod; each belt wheel is fixed at one end of the corresponding screw rod and connected with the corresponding alternating current servo motor; the other end of each screw rod is connected with a toggle rod mechanism; and each toggle rod mechanism is connected with connecting rod mechanisms and a slide block of a mechanical press. When the servo drive press works, the alternating current servo motors drive the screw rods to rotate through the belt wheels, the toggle rod mechanisms push the connecting rod mechanisms of the mechanical press to move, and the movement velocity and the position of the slide block are fed back to the serve motors through a signal output by a displacement sensor so that the motion property of the slide block can be adjusted in time.
Description
Technical field
The present invention relates to the structure of a kind of structure of forcing press, particularly a kind of servo drive press machine, belong to electromechanical integration technology area.
Background technology
At present in the punching machine of extensive use both at home and abroad, general adopt common AC asynchronous motor that can not speed governing to drive, motor is connected with flywheel by the V-belt transmission, and flywheel plays the key effect of stored energy, forging instantaneous towards workpiece, flywheel releases energy, after forging was finished towards work, the motor drives flywheel quickened rotation, made it return to original speed in forging before next workpiece, store enough energy, so that use in next working cycles.This type of drive is simple, cost is lower, but because Rotary Inertia of Flywheel is very big, AC induction motor rated slip rate is very little in addition, therefore, the rotating speed that is arranged in the rotary system after the flywheel is approximate constant a work period, and the transmission system of directly to drive the punching machine that have flywheel by motor speed adjusting realizes that the speed change difficulty is very big.
At present, can obtain constant torque characteristic below the basic rotating speed though variable-frequency control technique also occurs in some forcing presses, the basic above regulating frequency of rotating speed can also obtain constant output characteristic.But because forcing press mainly relies on flywheel that workpiece deformation institute energy requirement is provided, and frequency control way reduces the steady running speed of flywheel, may cause being out of shape required energy shortage, thereby the scope of application is subjected to certain restriction.
Summary of the invention
The structure that the purpose of this invention is to provide a kind of servo drive press machine overcome the deficiency that can't directly drive flywheel realization speed change by motor speed adjusting that existing forcing press exists, and frequency control way may cause the required energy shortage of workpiece deformation.This forcing press can be exported constant torque in the range of speeds, rotating speed has good controllability again, adapts to the requirement of the flow of metal speed of different Sheet Metal Forming Technologies.
The objective of the invention is to be achieved through the following technical solutions, the present invention is made up of symmetrically arranged AC servo motor and transmission mechanism, each transmission mechanism can be taken turns by belt pulley, leading screw, constitute with toggle link, belt pulley is fixed on an end of leading screw, and be connected with AC servomotor, the other end of leading screw connects elbow-bar mechanism, elbow-bar mechanism connects the linkage and the slide block of punching machine, during work, AC servomotor drives the leading screw rotation through belt pulley, promote the connecting rod mechanism movement of punching machine through elbow-bar mechanism, the movement velocity of slide block and the position signal feedback by displacement transducer output is to servomotor, and the kinetic characteristic of slide block is in time adjusted.
Beneficial effect: utilize AC servomotor because of be subjected to input signal control and make fast response, control accuracy height, characteristic stably turns round, it is applied on the punching machine, drive source as punching machine, rotating speed has good controllability, the constant torque of output in the range of speeds has good low speed and forges towards quickreturn characteristics, and the speed governing amplitude is big and convenient, response speed can save clutch and brake on the existing machinery forcing press.
