Abstract
The invention relates to a novel servo drive press machine, belonging to the technology field of the mechanical and electrical integration. The novel servo drive press machine is composed of an alternating current servo motor and a transmission mechanism which are arranged symmetrically, each transmission mechanism can be composed of a belt roller, a leading screw and a toggle rod, the belt roller is fixed at one end of the leading screw and is connected with the alternating current servo motor, the other end of the leading screw is connected with a toggle rod mechanism, the toggle rod mechanism is connected with a connecting rod mechanism of a mechanical press machine and a sliding block, when the novel servo drive press machine works, the leading screw is driven to rotate by the alternating current servo motor through the belt roller, the connecting rod mechanism of the mechanical press machine is pushed to move by the toggle rod mechanism, the moving speed and the position of the sliding block are fed back to the servo motor by the signal of a displacement sensor, and the moving characteristic of the sliding block is adjusted in time.
Description
Technical field
The present invention relates to a kind of punching machine, particularly a kind of novel 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 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 that existing forcing press exists, and frequency control way may cause the required energy shortage of workpiece deformation by motor speed adjusting.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, a kind of novel servo drive press machine, the linkage, slide block, the displacement detection system that comprise punching machine, it is characterized in that, described device is made up of symmetrically arranged AC servomotor and transmission mechanism, and the linkage that each transmission mechanism drives the punching machine respective side promotes slide block.Slide block decrease speed and position are regulated by displacement detection system control servomotor.
Transmission mechanism can be made of belt pulley, screw mandrel and elbow-bar mechanism, and belt pulley is fixed on an end of leading screw, and is connected with AC servo motor, and the other end of leading screw connects elbow-bar mechanism.
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.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
Further specify the present invention below in conjunction with drawings and Examples.
The present invention is made up of symmetrically arranged AC servo motor 3 and transmission mechanism, each transmission mechanism can take turns 4 by belt pulley, leading screw 5, constitute with toggle link 6, belt pulley 4 is fixed on an end of leading screw 5, and be connected with AC servomotor 3, the other end of leading screw 5 connects elbow-bar mechanism 6, elbow-bar mechanism 6 connects the linkage 1 and the slide block 2 of punching machine, during work, AC servomotor 3 drives leading screw 5 rotations through belt pulley 4, promote linkage 1 motion of punching machine through elbow-bar mechanism 6, the movement velocity of slide block and the position signal feedback by displacement transducer 7 output is to servomotor 3, and the kinetic characteristic of slide block is in time adjusted.
