Description
Technical field
The utility model relates to a kind of mechanical press servo driving device, belongs to electromechanical integration technology area.
Background technology
In the punching machine of extensive use at present both at home and abroad, generally adopt common AC asynchronous motor that can not speed governing to drive, motor is connected with flywheel by the V belt transmission.In punching machine, flywheel plays the key effect of storage power, forging instantaneous towards workpiece, mainly release energy, after forging is finished towards work by flywheel, the motor drives flywheel quickens rotation, making it return to original angular speed in forging before next workpiece, thereby store enough energy, is not directly to be supplied with by motor, but mainly supply with by flywheel, so power of electric motor just can reduce greatly.This type of drive is simple, cost is lower, but because Rotary Inertia of Flywheel is very big, AC asynchronous 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, thereby the transmission system of wanting directly to drive the punching machine that have flywheel by motor speed adjusting realizes that the speed change difficulty is very big.
Development along with Power Electronic Technique, ac variable speed technology has obtained constantly improving and improving, on forcing press, adopt frequency converter that the ac motor stator winding is carried out frequency conversion, transformation control, promptly on forcing press, adopt the associating type of drive of adjustable speed AC asynchronous motor-flywheel, can obtain the following constant torque characteristic of basic rotating speed, the basic above regulating frequency of rotating speed can also obtain constant output characteristic.But because the transmission system of band flywheel mainly relies on flywheel that workpiece deformation institute energy requirement is provided, and frequency control way reduces the steady running speed of flywheel, the energy that this workpiece deformation is required may cause being out of shape required energy shortage, thereby still there is deficiency in industrial practicality owing to reduce.
Summary of the invention
The purpose of this utility model is the deficiency that can't directly drive the transmission system realization speed change of the punching machine that has flywheel by motor speed adjusting that exists at the forcing press that existing AC asynchronous motor drives, frequency control way may cause the required energy shortage of workpiece deformation, both provided and can export constant torque in the range of speeds, rotating speed has a kind of mechanical press servo driving device of good controllability again.
The purpose of this utility model is achieved through the following technical solutions, a kind of mechanical press servo driving device, the linkage and the slide block that comprise punching machine, it is characterized in that described device is made up of symmetrically arranged AC servomotor and transmission mechanism, the linkage that each transmission mechanism drives the punching machine respective side promotes slide block.
Transmission mechanism can be made of small flywheel, leading screw and elbow-bar mechanism, and small flywheel is fixed on an end of leading screw, and is connected with AC servomotor, and the other end of leading screw connects elbow-bar mechanism.
The utility model 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 can save clutch and brake on the existing machinery forcing press rapidly.
Description of drawings
Fig. 1 is installed in structural representation on the punching machine for the utility model;
The specific embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is made up of symmetrically arranged AC servomotor 3 and transmission mechanism, each transmission mechanism can be by small flywheel 4, leading screw 5 and elbow-bar mechanism 6 constitute, small flywheel 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 small flywheel 4, the linkage 1 that promotes punching machine through elbow-bar mechanism 6 moves, and makes slide block 2 finish press work.
