Embodiment
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.
It is a kind of to make pinpoint device, including upper mould and lower mould, institute to the step pitch of progressive press tool referring to figs. 1 to Fig. 2
Mould is stated including upper clamping plate and the drift 10 of upper clamping plate lower surface is fixed on, the lower mould 20 include die shoe plate 210 and
The core rod 220 on die shoe plate is arranged at, is left between the core rod 220 and die shoe plate 210 between treating that slug sheet material passes through
There is the through hole 30 being correspondingly arranged for inserting for drift, core rod 220 goes out along sheet material in the middle part of gap, the core rod and die shoe plate
Material direction side has locating piece 40；
The middle part of locating piece 40 is by a backing pin 401 and core rod hinge connection, and the side of locating piece 40 towards the through hole is
Preceding toe 410, is rear heel 420 away from through hole side, and the core rod 220 has towards the one end in the discharging of sheet material 100 direction to be inserted
Enter the alignment pin 50 in core rod, the one end that the alignment pin 50 stretches into core rod is tapered, and the rear heel has and alignment pin
50 bellmouths 421 coordinated, the outside of alignment pin 50, which has, oppresses the elastic component that the conical end portion of alignment pin 50 supports rear heel,
The upper mould, which is provided with to hit, makes locating piece depart from the bump bolt 60 that alignment pin is rotated around hinged place on rear side of locating piece.
In the present embodiment, when the lower edge of the preceding toe 410 is contacted with die shoe plate, the described lower edge of rear heel 420 with
Leave to treat gap that slug sheet material 100 passes through between die shoe plate 210.
In the present embodiment, the elastic component is leaf spring 510, and the upper and lower ends of the leaf spring 510 are fixedly connected in core rod, plate
Alignment pin is supported in the middle part of spring.
During work,
