Specific embodiment
It is practical new below in conjunction with this to keep the objectives, technical solutions, and advantages of the embodiments of the present invention clearer
Attached drawing in type embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that is retouched
The embodiment stated is the utility model a part of the embodiment, instead of all the embodiments.Usually here in attached drawing description and
The component of the utility model embodiment shown can be arranged and be designed with a variety of different configurations.Therefore, below to attached
The detailed description of the embodiments of the present invention provided in figure is not intended to limit the range of claimed invention,
But it is merely representative of the selected embodiment of the utility model.
Referring to Figures 1 and 2, the utility model discloses a kind of pore stamping die, including dynamic model and cover half, the dynamic model pair
It answers cover half to be provided with formed punch 8 and cavity plate 4, formed punch 8 is corresponded in the cavity plate 4 and is provided with baffle plate 9 and upper de- plate 10, the backstop
Plate 9 offers the pilot hole being adapted to the bar portion of formed punch 8, and the upper corresponding pilot hole of de- plate 10 offers the red needle with formed punch 8
The perforation of adaptation, the formed punch 8 can be such that red needle is pierced by out of perforation under the guiding role of pilot hole.Further, described dynamic
Mould includes the upper die holder 1, upper padding plate 2 and upper clamp plate 3 being sequentially connected, the upper clamp plate 3 close to one end of upper padding plate 2 be provided with
The mounting hole of the shoulder adaptation of formed punch 8, the formed punch 8 are installed in mounting hole and are compressed by upper padding plate 2, the mounting hole,
Pilot hole and the coaxial arrangement of perforation.Wherein one or more is set as needed in the quantity of formed punch 8, and correspondence is opened on dynamic model and cover half
If installing hole location, cooperation hole location accordingly.
Due to traditional punching die, dynamic model only includes upper die holder 1, upper padding plate 2, upper clamp plate 3 and cavity plate 4 or upper de- plate
10, formed punch 8 is fixed by upper padding plate 2 and the installation of upper clamp plate 3, and 8 lower end of formed punch can be pierced by out of cavity plate 4 or upper de- plate 10, upper folder
The 8 longer and easy forced breakage of bar portion length of formed punch between plate 3 and cavity plate 4 or upper de- plate 10.And sheet using the above structure
Utility model increases baffle plate 9 compared with traditional structure, is oriented to, is limited, Ke Yibao by bar portion of the baffle plate 9 to formed punch 8
Card mould and die accuracy can play the role of pipe position to the tail end of formed punch 8 again, and then in punch process, will not be because of powerful punching
Power causes formed punch 8 or red needle to be broken, and advantageously reduces maintenance cost and improves production efficiency, and formed punch 8 is easily broken when aperture is rushed in solution,
Improve production efficiency and reduction repair a die time and cost the problem of, have important meaning to the popularization of punching die structure, it is practical
Property is strong.
