Specific embodiments
Below in conjunction with accompanying drawing, the present invention is described in detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, a kind of bars and tubes material blanking machine of AC servo machinery driving edge cam, comprise that the identical edge cam of circumferential symmetrical expression layout three cover forges mechanism, in order to realize fast precise blanking, each mechanism that forges comprises an AC servo synchronous motor 9 being loaded on main frame body 10, AC servo synchronous motor 9 is connected with the upper axle of cam 8 by decelerator, match with the top of push rod 7 in the lower surface of cam 8, between the middle part of push rod 7 and main frame body 10, back-moving spring 12 is housed, the lower end of push rod 7 is connected with adjustment nut 4 by gib block 3, adjustment nut 4 is by connecing tup 2 in screw thread, blanking mold 1 is housed on tup 2, between three moulds 1, bars and tubes material to be processed 15 is set, adjustment nut 4 overlaps 6 external mode transfer worm gears 5 by mode transfer simultaneously, mode transfer worm gear 5 coordinates with worm screw 11, worm screw 11 provides power by the little servomotor 13 being loaded on main frame body 10,
Cam 8 and push rod 7 form edge cam, three rollers 14 fixing with respect to push rod 7 positions are housed on push rod 7, the impulse stroke of push rod 7 is promoted to realize by three rollers 14 by cam 8, can only axially move because push rod 7 is subject to the constraint of its spigot surface, realize with this straight-line conversion that rotatablely moves.
As shown in Figure 6 and Figure 7, problem for convenience of description, cam 8 is expanded into planar graph along its bus, because designed cam curve is circumferential symmetrical structure, get its half and carry out analytic explanation, before initialization, first rotating three cams 8 makes three molds 1 all in upper dead center position separately, after installing material, first controlling respectively three AC servo synchronous motors 9 drives three cams 8 to turn an angle, make an AC servo synchronous motor 9 drive a cam 8 to rotate 60 °, now a mould 1 is in its lower dead point position, the active force maximum that bars and tubes material 15 is applied, make No. two AC servo synchronous motors 9 drive No. two cams 8 to rotate 140 °, now No. two moulds 1 are just crossed its upper dead center position and are about to past bottom dead centre motion, make No. three AC servo synchronous motors 9 drive No. three cams 8 to rotate 100 °, now No. three moulds 1 have been crossed its bottom dead centre just toward top dead-centre motion, mix up after the initial angle of three cams 8, allow three AC servo synchronous motors, 9 synchronous same-speeds turn round.
Operation principle of the present invention is:
The AC servo synchronous motor 9 being arranged on main frame body 10 is with moving cam 8 to rotate, thereby the axially-movable that the rotation of cam 8 is converted into tup 2 by push rod 7 and adjustment nut 4 drives blanking mold 1 to do axial feed motion, to realize the object that bars and tubes material 15 is radially forged, the backhaul of tup 2 is to apply reaction force by back-moving spring 12 to push rod 7, thereby promotion push rod 7 runs back, driven mold 1 turns back to its top dead-centre.
The little servomotor 13 being arranged on main frame body 10 drives mode transfer worm gear 5 to rotate by worm screw 11, because gib block 3 constraints make to only have axial freedom there is no the circumferential free degree between mode transfer worm gear 5 and adjustment nut 4, thereby make mode transfer worm gear 5 drive adjustment nut 4 to rotate, adjustment nut 4 is connected with tup 2 by screw thread, thereby tup 2 is moved up and down, thereby reach the object that regulates mold height.
Before initialization, first three cams 8 are forwarded to zero phase place and make three cover blanking molds 1 all in upper dead center position separately, the region in the middle of such three molds 1 is also relatively large, is beneficial to the bars and tubes material 15 that is installed.After installing material, first controlling respectively three AC servo synchronous motors 9 drives three cams 8 to turn an angle, make an AC servo synchronous motor 9 drive a cam 8 to rotate 60 °, now a mould 1 is in its lower dead point position, the active force maximum that bars and tubes material 15 is applied; Make No. two AC servo synchronous motors 9 drive No. two cams 8 to rotate 140 °, now No. two moulds 1 are just crossed its upper dead center position and are about to past bottom dead centre motion; Make No. three AC servo synchronous motors 9 drive No. three cams 8 to rotate 100 °, now No. three moulds 1 have been crossed its bottom dead centre just toward top dead-centre motion, mix up after the initial angle of three cams 8, allow three AC servo synchronous motors, 9 synchronous same-speeds turn round, such three tups 2 apply certain moment of flexure just in turn respectively bars and tubes material 15, thereby realize the axial object that reaches precise blanking of hitting in turn to bars and tubes material 15.
