Description
Technical field
The utility model is related to wool felt collar field, and in particular to a kind of wool felt collar cutting tool.
Background technology
Felt collar is HM, HHM, the strength member of a dust-proof damping in HHFM reinforced concrete sealed door hinge pages.It is enclosed
Dust-proof effect is can be only achieved with the cylindrical tight fit of hinge.But the soft bad processing of the material of wool；Per boring, door needs number
Amount is more, so of large quantities.
Existing processing method is shearing and two kinds of punching by hand, and inside and outside circle is irregular during shearing, and plane is into shape of cleaving, effect
It is low；When rushing by hand, inside and outside circle decentraction, Life of Punch Die is short.For the neat zero defect of felt collar inside and outside circle, coplanar flat is together without recessed
It is convex.Cutting tool of the present utility model can be smooth neat with rapid processing inner hole outer circularity, the felt collar of coplanar flat no concave-convex.
Utility model content
In view of the shortcomings of the prior art, the purpose of this utility model smooth neat, the plane that is to provide a kind of inner hole outer circularity
Smooth no concave-convex, it is ensured that the axiality of inside and outside circle, fully meets the wool felt collar cutting tool of product quality requirement.
The technical problem that the utility model is solved can be realized using following technical scheme：A kind of wool felt collar cuts work
Dress, including blanking punch, wherein the blanking punch includes cut surface, cutting external mold and the circle centre position of cutting internal model, wherein cut surface
Provided with positioning hole, cutting external mold is connected with cutting internal model with the lower surface of cut surface, and cutting external mold is located at respectively with cutting internal model
At the outer rim and positioning hole of cut surface, cut surface is provided with the blanking of some annular spreads between cutting external mold and cutting internal model
Hole, cut surface is provided with positioning sleeve in the top of positioning hole, and positioning sleeve includes connecting rod and locating rod, wherein connecting rod successively from top to bottom
It is connected in drill chuck, locating rod is located in positioning hole.
It is preferred that, the cutting internal model and the surface of the cutting external mold are provided with some heat emission holes.
It is preferred that, the center of the positioning sleeve is provided with the slug hole of vertical insertion.
It is preferred that, the lower surface of the cutting internal model is lower than the lower surface of the cutting external mold.
It is preferred that, the positioning sleeve is provided with limiting plate between connecting rod and location-plate, and the lower surface of limiting plate is cut with described
The upper surface of face is overlapped.
Beneficial effect is：The product that this wool felt collar cutting tool is processed, inner hole outer circularity is smooth neat, coplanar flat
No concave-convex, it is ensured that the axiality of inside and outside circle, fully meets product quality requirement.The processing method of this cutting tool is simple, easily
Operation, one time-completion shaping；Outward appearance and size all meet drawing requirement, it is ensured that product quality：Effect is improved, is reduced into
This, present qualification rate is improved, and reduces the raw material originally wasted, and can make full use of material space, improves product
Utilization rate.
