Description
Technical field
The invention belongs to mechanical manufacturing field, particularly a kind of mechnical servo that is applied to NC turret punch machine drives main drive.
Background technology
Mechanical servo numerical control turret punching machine be automatic replacing and the sheet material of a kind of automatic transport of accomplishing plate, punch die the high efficiency Precision Machining, be suitable for the pressing equipment of the servo Punching Technology of thin plate continuous high speed; But high-efficiency and precision is processed various sheet-metal press working parts; Its essential characteristic is high efficiency, high accuracy, energy-saving and environmental protection and automation, has represented the developing direction of NC turret punch machine.Key technologies such as thermal balance technology under mechanical servo numerical control turret punching machine collection complete machine structure optimisation technique, servo-drive main transmission technology, servo-drive punching press control technology, feeding Mechanism Design and control technology, servo main transmission run up and digital control system integrated intelligence technology are one; Possess automatically, at a high speed, accurate three essential characteristics; Being widely used in high-tech areas such as Aero-Space, automobile, generating equipment, information, household electrical appliances, is one of great equipment for guaranteeing the necessary independent research of economy and national defense safety.
At present; High-speed hydraulic punch systems or the main transmission of common electric machine machinery are adopted in the punching press main transmission of NC turret punch machine more; The NC turret punch machine of hydraulic pressure main transmission or the main transmission of common electric machine machinery needs only start, the running that main motor will not stop a moment, and the dry run consumed power is more.The servo valve of hydraulic system control oil circuit is high to the requirement of oil product, and hydraulic oil needs periodic replacement, will guarantee also that in maintenance process oil circuit is not contaminated.During lathe work, the impact noise when the high-pressure oil passage valve commutates at a high speed is bigger.
Compare with hydraulic pressure main transmission NC turret punch machine, mechanical servo numerical control turret punching machine has energy-saving and environmental protection and safeguards simple, reliability advantages of higher.The external punch press producer hydraulic pressure main transmission NC turret punch machine that progressively stops production, then the NC turret punch machine of mechnical servo main transmission only is provided.Compare with the main transmission of common electric machine machinery, the main transmission of servomotor machinery has absolute predominances such as high speed, high accuracy, high energy saving and stroke be variable, is that the upgrading in the epoch of striding is technological.
Commercialization manufacturing machine servo digital control rotating tower punch producer mainly contains the field, Tian Tianhe village of Japan, the fragrant treasured of Finland in the world, and wherein the sales volume in day field is maximum, description is also more.The frame for movement of the servo main transmission punch press of EM series mechanical in it field is the simplest, and the mechanical transmission structure with traditional bent axle, connecting rod, vertical slipper is identical basically.With the high-power servo principal axis motor of customization, common electric machine and flywheel in the traditional mechanical structure have been replaced at crankshaft two end.Its shortcoming is that the servo principal axis motor cost of customization is very high, and the electrical control that the forward and reverse rotation of low-angle drives requires high (journey contrast in a state of excitement of identical step, the motor corner of EM is less).In view of the foregoing; It field company has developed the relatively punch press of the economic servo main transmission of AC series mechanical again; Wherein servomotor has adopted the high-power servomotor of little inertia of digital control system manufacturer standard configuration, and motor directly drives great lead ball lead screw through safety coupling; Leading screw drives cross sliding clock and makes horizontal reciprocating movement; Cross sliding clock is made the reciprocally swinging of certain angle through hinge coupling bar driven rotary lever; Rotating lever drives the ramming motion that vertical slipper is realized above-below direction.This has also brought new problem: the motor transformational relation calculation of complex that moves up and down with vertical slipper that rotatablely moves, and that electrical control requires is high, difficulty is big, and stroke is little at full capacity.
The mechnical servo main transmission structure in field, village has adopted the other toggle rod type reinforcement drive mechanism of putting crank, and servomotor drives the crank rotation through high-power reduction box; Crank drivening rod, connecting rod drive the toggle link swing; Toggle link drives the ramming motion that vertical slipper produces above-below direction.Its shortcoming is: crank adds the transformational relation calculation of complex that moves up and down of the dual stack generation vertical slipper of toggle link, and frame for movement is complicated, and the desired height size is bigger.
The servo main transmission structure of fragrant precious E series has adopted the ball-screw of big helical pitch to promote the horizontal movement that cross sliding clock is made prime, and the back level is transformed into vertical slipper when moving up and down, and fragrant treasured has adopted more simple voussoir, roll shaft structure.Therefore, required motor power is bigger, and the dynamic characteristic of motor is had relatively high expectations.
