Specific embodiments
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the mechanical type bars and tubes material blanking machine that a kind of a plurality of alternating current servo motor directs drive, complete machine adopts three-plate type structure, and along circumferential uniform three covers identical forge mechanism in order to realize fast precise blanking.
The mechanical type bars and tubes material blanking machine that a kind of a plurality of alternating current servo motor direct drives, comprise main frame body 15, main frame body 15 and two side plates 16 link together by pin 14, the large servomotor 17 being equipped with on side plate 16 is connected with bent axle 10 by decelerator, on bent axle 10, cover has Large lining 9 and connecting rod 8, connecting rod 8 is connected with jacking block 7 with bearing pin 12 by little lining 11, jacking block 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, adjustment nut 4 overlaps 6 external mode transfer worm gears 5 by mode transfer simultaneously, mode transfer worm gear 5 coordinates with worm screw 13, worm screw 13 is driven by the little servomotor 18 being loaded on side plate 16.
Operation principle of the present invention is:
The large servomotor 17 band dynamic crankshafts 10 that are arranged on side plate 16 rotate, thereby the axially reciprocating that the rotation of bent axle 10 is converted into tup 2 by connecting rod 8, jacking block 7 and adjustment nut 4 drives blanking mold 1 to do axial reciprocating motion, to realize the object that bars and tubes material is radially forged to blanking.
The little servomotor 18 being arranged on side plate 16 drives worm gear 5 to rotate by worm screw 13, because gib block 3 constraints make to only have axial freedom and the circumferential free degree of nothing 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.
As shown in Figure 5 and Figure 6, first three bent axles 10 are all forwarded to maximum phase place separately and make three cover blanking molds 1 all in upper dead center position separately before initialization, the regions in the middle of such three cover blanking molds 1 are also relatively large, are beneficial to the bars and tubes material that is installed.After installing material, control first respectively three large servomotors 17 and turn an angle, make motor Rotate 180 ° No. one, now a mould is in its lower dead point position, and the active force that blank is applied is maximum; Make 60 ° of No. two motor rotations, now No. two moulds are just crossed its upper dead center position and are about to past bottom dead centre motion; Make 300 ° of No. three motor rotations, now No. three moulds have been crossed its bottom dead centre just toward top dead-centre motion.Mix up after the initial angle of three large servomotors 17, then allow three large servomotor 17 synchronous same-speeds turn round, such three tups just apply certain moment of flexure to blank respectively in turn, thereby realize the axial object that reaches precise blanking of hitting in turn to bars and tubes material.
