Abstract
The correcting latch structure with discharging axis being used on stepping punching mould of the utility model, including pilot pin and discharging axis, the pilot pin includes the taper bolt of lower part and the cylinder on top, there is symmetrical axis hole in the lower cone pin both sides of cylinder, discharging axis is fitted in axis hole, the lower end of discharging axis is extended downwardly from axis hole, lead screw is equipped in cylinder, the lower end of lead screw is threadedly coupled with the internal thread hole in taper bolt centre, spring is set on lead screw, one end of spring acts against the axle cap end of discharging axis upper end, the other end acts against on the nut of lead screw upper end.It with compact-sized, occupies little space, pilot pin and discharging axis relative close ensure that material strip is indeformable, the repair and replacement time reduced, the advantages of improving work efficiency.
Description
Technical field
The utility model is related to a kind of correcting latch structures with discharging axis on stepping punching mould.
Background technology
Stepping punching mould includes the upper padding plate being connected with upper die holder, and cope plate, lower die are fixedly connected with below upper padding plate
Plate is fixed on lower die holder, and pilot pin is housed on cope plate.It is located to be equipped on cope plate in the both sides of pilot pin and symmetrically unloads
Expect axis.It when punching press, is rushed workpiece and is moved forward under the drive of material strip, often moved primary rear pilot pin and need to be inserted on material strip
In pin hole, then punching press, when punching press, the lower end of pilot pin be inserted into lower die it is corresponding inserting in the hole, when rushing Bi Kaimo, discharging
Axis abuts against material strip, and pilot pin is made to be extracted from the hole on material strip, and then material strip moves forward once again, and so on.This structure
Pilot pin and the cooperation of discharging axis are easy that material strip is made to be deformed, mainly since pilot pin and discharging axis are separate structure, relatively
There is a certain distance, and the pilot pin of this structure and discharging axis also need to enough spaces and can just be arranged.
Invention content
The purpose of this utility model be to provide it is a kind of it is simple in structure, occupy little space, pilot pin and discharging wheelbase from it is relatively close,
The on-deformable correcting latch structure with discharging axis on stepping punching mould of compact overall structure, material strip.
The correcting latch structure with discharging axis being used on stepping punching mould of the utility model, including pilot pin and discharging
Axis, the pilot pin include the taper bolt of lower part and the cylinder on top, have symmetrical axis in the lower cone pin both sides of cylinder
Hole is fitted with discharging axis in axis hole, and the lower end of discharging axis is extended downwardly from axis hole, is equipped with lead screw in cylinder, under lead screw
End is threadedly coupled with the internal thread hole in taper bolt centre, spring is set on lead screw, one end of spring acts against discharging axis
The axle cap end of upper end, the other end act against on the nut of lead screw upper end.
The correcting latch structure with discharging axis being used on stepping punching mould of the utility model, due to pilot pin and discharging
Axis is set as an entirety, compact-sized, occupies little space, and pilot pin and discharging axis relative close ensure that material strip is indeformable, subtract
It few repair and replacement time, improves work efficiency.
Description of the drawings
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is the structural schematic diagram of pilot pin shown in FIG. 1；
Fig. 3 is the structural schematic diagram of the utility model installation in a mold.
Specific implementation mode
As shown in Figure 1, 2：The correcting latch structure with discharging axis being used on stepping punching mould of the utility model, including
Pilot pin 1 and discharging axis 6.Pilot pin 1 includes the cylinder of the taper bolt and top of lower part.Have in the lower cone pin both sides of cylinder
Symmetrical axis hole 10 is fitted with discharging axis 6 in axis hole 10, and the lower end of discharging axis 6 is extended downwardly from axis hole 10.It is set in cylinder
There are lead screw 7, the lower end of lead screw 7 to be threadedly coupled with the internal thread hole in taper bolt centre, spring 8, spring are set on lead screw 7
8 one end acts against the axle cap end of 6 upper end of discharging axis, and the other end acts against on the nut 9 of 7 upper end of lead screw.
As shown in Figure 3：When installation, this pilot pin structure setting between upper padding plate 4 and cope plate 3, have in lower template 5 with
Pilot pin is inserted into hole accordingly, and 2 be the material strip forward by workpiece is rushed of the drive between cope plate 3 and lower template 5.Punching press
When, the lower end of pilot pin 1 is inserted into accordingly inserting in the hole in lower die 5, and when rushing Bi Kaimo, discharging axis 6 abuts against material strip 2, makes to lead
Hole of the positive pin 1 from material strip is extracted, and then material strip 2 moves forward once again, and so on.With compact-sized, occupy little space,
Pilot pin and discharging axis relative close ensure that material strip is indeformable, the repair and replacement time are reduced, the advantages of improving work efficiency.
