Abstract
The invention discloses an under-drive punch press which comprises a rack, an upper working platform, a servo drive mechanism, a crankshaft connecting rod mechanism and a toggle rod mechanism, wherein the rack comprises a bottom plate and four upright posts; the upper working platform slides along the upright posts; the servo drive mechanism, the crankshaft connecting rod mechanism and the toggle rod mechanism are arranged at the lower part of the upper working platform; the toggle rod mechanism comprises an upper toggle rod, a lower toggle rod and a toggle shaft; one ends of the upper toggle rod and the lower toggle rod are connected by virtue of the toggle shaft; the servo drive mechanism drives the crankshaft connecting rod mechanism; the other end of the connecting rod of the crankshaft connecting rod mechanism is connected to the toggle shaft of the toggle rod mechanism in a sleeving manner; the other end, namely the upper end, of the upper toggle rod is hung onto a mounting shaft below the upper working platform; the other end, namely the lower end, of the lower toggle rod is fixed on the bottom plate by virtue of a second mounting shaft; and four corners of the upper working platform are arranged on the upright posts in a sleeving manner, and the upper working platform moves up and down along with the upright posts.
Description
One, technical field
The present invention relates to motion or the transmission mechanism of servo-pressing machine (punch press), especially the motion of underdrive punch press or transmission mechanism.
Two, background technology
Servo-pressing machine is by the pressing machine of driven by servomotor (punch press), and servo-pressing machine can accurate controlled pressure stroke, and press again can Real-Time Monitoring press-mounting stroke and pressure assembling force with pressure assembling force sensor simultaneously; Servomotor can Direct driver punch press.
Chinese patent discloses 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 underdrive punch press of prior art and drive motion mechanism thereof, underdrive punch press has original structure and using function.
Three, summary of the invention
The present invention seeks to, propose a kind of underdrive punch press and drive motion mechanism thereof, underdrive punch press has original structure and using function.Underdrive, workbench is positioned at top, and definitely all without oil pollution from theory to reality, without the need to electroplating after non-ferrous metal pieces punching press, the terminal that punching press is good, lead frame directly assemble, and stamping parts is follow-up scraps and disposal cost in reduction.
Technical scheme of the present invention is: a kind of underdrive punch press, comprises frame, upper workbench, servo-actuating device, crankshaft connecting rod system and elbow-bar mechanism, and described frame comprises base plate, four root posts, upper workbench slides along column, upper workbench bottom is servo-actuating device, crankshaft connecting rod system and 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 servo-actuating device driving crank linkage, the connecting rod other end of crankshaft connecting rod system 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 below workbench, the other end of lower elbow lever and lower end are fixed by the second installation shaft and base plate, upper workbench corner is placed on column and moves up and down along column.
Bed die is installed on workbench, and upper workbench top is provided with top shoe, and counterdie is installed in the bottom of top shoe.
Operation principle of the present invention is: when servo-actuating device driving crank rotates, drivening rod seesaws, the elbow axle that the other end of connecting rod is socketed in elbow-bar mechanism drives the motion of elbow-bar mechanism, and the other end of upper elbow lever and upper end make workbench slip and mold movement; The press work of driven mold.
Beneficial effect of the present invention, the present invention easily drives punch press with high speed stamping.Underdrive, workbench top is definitely all without oil pollution from theory to reality, and without the need to electroplating after non-ferrous metal pieces punching press, the terminal that punching press is good, lead frame directly assemble, and stamping parts is follow-up scraps and disposal cost in reduction; Four angle down push-and-pulls when workbench slides.Most edge can uniform stressed, and offset load resistance is stronger, and deflection is minimum.Can prepare the punch press of all size as the Multiple Type of 20-3000T, volume is little, highly low.The present invention can simplify and reduce drive mechanism, noise is less, reliable operation.
Four, accompanying drawing explanation

Five, detailed description of the invention
As shown in the figure, top shoe 1, four root post 2, working plate 3, upper workbench 4, lower elbow lever 5, installation shaft 6, upper elbow lever 7, elbow axle 8, servo-actuating device 9, connecting rod 10, base plate 11.
Underdrive punch press of the present invention comprises frame, described frame comprises base plate, the orthogonal distribution of four root posts, also the framework of whole machine is formed, along the upper workbench that column slides, upper workbench bottom is servo-actuating device, crankshaft connecting rod system and 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 servo-actuating device driving crank linkage, 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 below workbench, the other end of lower elbow lever and lower end are fixed by the second installation shaft and base plate, upper workbench corner is placed on column and moves up and down (under the drive of crankshaft connecting rod system and elbow-bar mechanism) along column.
Bed die is installed on workbench, and upper workbench top is provided with top shoe, and counterdie erecting bed is installed in the bottom of top shoe.
When servo-actuating device driving crank rotates, drivening rod seesaws, and the elbow axle that the other end of connecting rod is socketed in elbow-bar mechanism drives the motion of elbow-bar mechanism, and the other end of upper elbow lever and upper end make workbench slip and mold movement; The press work of driven mold, top shoe 1 upper platen and upper workbench 4 and working plate 3 are for installing clamping mold.
