Having a hole, location, it coordinates piercing punch to realize punching；
Piercing punch 6, piercing punch 6 is the column construction matched with hole, location, and piercing punch 6 hangs down and is located at fixed block 5
Bottom and just to location hole arrange.A few font parts match with punching concave die, and upper bolster drives piercing punch to transport downwards
Dynamic, piercing punch 6 sequentially passes through and is punched 10 and hole, location, it is achieved the punching to a few font parts.The letter of this apparatus structure
Single, easy to use.
It addition, combine shown in Fig. 2 and Fig. 3, also setting up a feeding pressure mechanism on piercing punch, it includes being placed in lower fixing
The binder block 8 at block 12 top, offers via in the middle part of binder block 8, piercing punch 6 freely passes along via, in the present embodiment, and pressure
The bottom surface of material block 8 is its lower binder surface；On piercing punch 6 between upper fixed block 5 and binder block 12, pretension is provided with a bullet
Spring 7, the contact of binder block 8 lower surface is punched part 10, and spring 7 coordinates binder block 8 to play binder effect so that punch side is tightr
Fit with punching concave die 9, improve the accuracy of punching.If there being shape binder block to need conformal to process on part.Wherein,
Spring 7 is connected with binder block 8 so that while upper bolster 1 drives piercing punch 6 punching, give acting force of the spring, and then spring
It is applied on binder block 8 realize binder.
So that during punching, the relative motion between upper bolster and die shoe is steady, at die shoe towards upper bolster one
Side is provided with multiple lead 3, offers the pilot hole matched with lead 3 at the top of die shoe 2, is provided with in pilot hole
Guide pin bushing 4.The motion guide of upper and lower mould is realized by coordinating of lead 3 and pilot hole.
In the present embodiment, being provided with a flange on the top of piercing punch 6, the middle part of upper fixed block offers installing hole, peace
The top in dress hole communicates with the first stopper slot 51 of a upward opening, and upper fixed block is stretched out along installing hole in the bottom of piercing punch,
The flange of piercing punch is fastened in the first stopper slot 51；Realize piercing punch 6 with this to be connected with upper the fixing of fixed block 5, its
On in, fixed block can use welding or screw connecting mode to be fixed on upper bolster.
It addition, be provided with a second downwardly open stopper slot 52 along the edge of installing hole in the bottom surface of upper fixed block 5, its
