Move powder swivel nut top and the bottom and be provided with locknut and following locknut, the adjustment screw rod stretches out from moving in the powder swivel nut, moves powder swivel nut and following locknut and matches with the big end nut of adjusting screw rod, and the little end nut of last locknut and adjustment screw rod matches.
The invention has the beneficial effects as follows: 1) symmetry be installed in side before and after the mould bases, utilize cylinder to control powder transferring, it is reliable and stable to transfer strength; 2) be arranged on the mould bases outside, adjust move the powder time and move powder apart from the time simple and convenient, the convenient installation and debugging; 3) the present invention utilizes the locknut locking swivel nut of different-diameter and pitch, thereby guarantees to move the stable of powder time and distance.
Description of drawings
Among the figure 1 for cope match-plate pattern, 2 for move powder cylinder support, 3 for move the powder cylinder, 4 for adjust screw rod, 5 for last locknut, 6 for move the powder swivel nut, 7 for locknut down, 8 for move the powder bolt, 9 for move the powder limit base, 10 for bolt, 11 for the cylinder support, 12 for unsteady punching, 13 be that reset cylinder, 14 is a fixing punching under cylinder block, 15 is.
The specific embodiment
Symmetry of the present invention be arranged on side before and after the mould bases, every side comprises by moving powder cylinder support 2 and is connected and moves powder cylinder 3 on the cope match-plate pattern 1, the underpart of the piston rod that moves powder cylinder 3 connects adjusts screw rod 4, adjust screw rod 4 outer being arranged with and move powder swivel nut 6, move in the powder swivel nut 6 under extend and move powder bolt 8, move powder swivel nut 6 below be provided with that restriction moves 6 times line displacements of powder swivel nut move powder limit base 9, move the bolt 10 that upwards extends in the powder limit base 9 and move 8 cooperations of powder bolt, moving powder limit base 9 bottoms is connected with and the reset cylinder 13 of fixedlying connected with following fixedly punching 15, the piston rod of reset cylinder 13 extends to and moves in the powder limit base 9, and piston rod is connected with the unsteady punching 12 of make-up machine by bolt 10.
Move powder swivel nut 6 top and the bottom and be provided with locknut 5 and following locknut 7, adjustment screw rod 4 stretches out from moving in the powder swivel nut 6, moves powder swivel nut 6 and following locknut 7 and matches with the big end nut of adjusting screw rod 4, and the little end nut of last locknut 5 and adjustment screw rod 4 matches.
The big end screw thread of adjustment screw rod 4 of the present invention is connected with last locknut 5, the small end screw thread with move powder swivel nut 6, down locknut 7 links to each other, can guarantee like this to move the position of powder swivel nut 6 in case determine, can be effectively by last locknut 5 and 7 lockings of following locknut, prevent loosening displacement, move powder cylinder 3 epicoeles and keep normal ventilation, move the powder cylinder piston rod and be in the state of stretching out.The present invention moves powder limit base 9 and is bridge-type structure, is installed on the cylinder body of reset cylinder 13, and the cylinder body of reset cylinder 13 is fixed on down fixedly on the punching 15 by cylinder block 14, and the piston rod of cylinder 13 passes through bolt 10 and links to each other with unsteady punching 12 with cylinder support 11.Reset cylinder 13 cavity of resorptions of the present invention keep normal ventilation, and to guarantee the quick condition of unsteady punching 12, the epicoele of reset cylinder 13 in needs, to the inflation of reset cylinder 13 epicoeles, satisfies the action needs by solenoid control.
