A kind of NC turret punch machine single servo motor main transmission structure disclosed in 101697437A, it comprises AC servo motor, bent axle, connecting rod and slide block, described AC servo motor is arranged on one end of bent axle, the bent axle being connect driving by alternating current servo motor direct is connected with connecting rod, connecting rod is connected with slide block again, forms a planar linkage mechanism.But rotating tower punch is applicable to plate stamping, its tonnage is very little, is generally no more than 40-50T.
The unexposed two point of prior art or multiple spot punch press connecting rod push-and-pull drive motion mechanism, and the design of the raising of the offset load resistance of punch press and stamping press is all very important.
Three, summary of the invention
The present invention seeks to, propose a kind of two point or multiple spot punch press connecting rod push-and-pull toggle link motion, offset load resistance is stronger, utilizes Dual-Servo Motor+toggle link to produce and at least produces stamping press on the both sides of work bench of punch press simultaneously, greatly can improve the tonnage of punch press.
Technical scheme of the present invention is: two point punch press connecting rod push-and-pull toggle link motion, and comprise frame, servo-actuating device, crankshaft connecting rod system and elbow-bar mechanism are overlapped in front and back two, slide block mechanism and workbench and mould erecting bed, described frame comprises column and entablature, described entablature is provided with servo-actuating device and crankcase, described crankshaft connecting rod system is arranged in crankcase, described servo-actuating device driving crank linkage is also fixed on crankcase, described elbow-bar mechanism comprises, lower elbow lever and elbow axle, on, one end of lower elbow lever is connected by elbow axle, the other end of described connecting rod is socketed on the elbow axle of elbow-bar mechanism, the other end of upper elbow lever and upper end are hanging connected in the installation shaft of entablature, the other end of lower elbow lever and lower end are fixed by the second installation shaft and slide block, described slide block mechanism is positioned at bottom entablature, the track that slide block and frame are installed coordinates and along orbital motion, described mould erecting bed is installed on the bottom of slide block, described counterdie erecting bed is fixed on frame and is positioned at the below of slide block.
Operation principle of the present invention is: when servo-actuating device driving crank 2 rotates, drivening rod 3 seesaws, the elbow axle that the other end of connecting rod is socketed in elbow-bar mechanism drives the motion of elbow-bar mechanism, described elbow-bar mechanism comprises, lower elbow lever and elbow axle, on, one end of lower elbow lever is connected by elbow axle, described, the other end of upper elbow lever and upper end are hanging connected in the installation shaft of entablature, the other end of lower elbow lever and lower end are fixed by the second installation shaft and slide block connecting axle 7-1 and slide block, on, swing between lower elbow lever installation shaft and the second installation shaft, described slide block mechanism is positioned at bottom entablature, the track that slide block and frame are installed coordinates and along orbital motion, described mould erecting bed is installed on the bottom of slide block, servo-actuating device motion direction of rotation is simultaneously contrary, when respectively to when strutting elbow-bar mechanism outward, the other end of lower elbow lever and lower end are with movable slider to move upward by the second installation shaft and slide block connecting axle 7-1, during contraction, lower elbow lever drives slide block to move downward, and due to elbow-bar mechanism leverage and the downward potential energy of quickening itself, can produce larger stamping press.Two point of the present invention or multiple spot punch press, make slide block pump to both sides push-and-pull elbow-bar mechanism and carry out punching press.
Beneficial effect of the present invention, at least front and back two are had to overlap servo-actuating device, crankshaft connecting rod system and elbow-bar mechanism simultaneously to slide block effect, three covers or more servo-actuating device, crankshaft connecting rod system and elbow-bar mechanism is not got rid of yet, the offset load resistance of punch press is stronger, servomotor is utilized to drive crankshaft rotating, connecting rod is moved up and down to both sides (front and back) push-and-pull toggle link band movable slider, and toggle link is positioned at the outermost end of slide block.The double dynamical pressure provided is more balanced, avoids single power to have difficulty on design selection and cost factor.
The present invention adopts the structure of servomotor+toggle link, namely by lever principle to slide block effect, strength is multiplied, power saving, can simplify and reduce drive mechanism, noise is less, energy transfer efficiency is high, more energy-conservation, and reliable operation is easy to maintenance.The present invention especially can be applied to large-tonnage Pressesservo, can reach the punch press of 500-2000T level.
