Abstract
The invention discloses a concave accessory, which is a cylinder structure. One end of the cylinder is a smooth plane structure. The other end of the cylinder is a concave structure with two ends which are warped up. The center of the concave accessory is a hollowed-out structure. The concave accessory is an integral structure which is molded in one step. The concave accessory disclosed by the invention has the advantages that since the concave accessory is in close fit with other parts which are matched with the circular-arc-shaped concave structure of the concave accessory, the occupied space is small and the effect is good; since the product is formed by adopting a powder metallurgy one-step molding technique, the concave accessory is convenient to process, the product performance is stable, the mechanical strength is high and the cost is low.
Description
Technical field
The present invention relates to field of powder metallurgy, particularly relate to a kind of female fitting.
Background technique
Punch press is carried out repeatedly in man-hour requirement to general female fitting, car die worker combines adding, and has so just increased the fussy degree of work, in addition, because being repeatedly processes and combine, easily causes the situation of the lower even fracture of pressing plate compressive strength to occur.Middle Comparision is many, and material and electric resources have also been caused to unnecessary waste, has increased financial burden to enterprise simultaneously, has limited the benefit of enterprise, is unfavorable for the development of enterprise.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of female fitting, and this female fitting has laminating closely, easy to process, and product performance are stable, and mechanical strength is high, the feature that cost is low.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of female fitting is provided, described female fitting is a cylindrical structure, described cylindrical one end is smooth flat structure, the described cylindrical the other end is the concave structure that two ends upwarp, described female fitting center is a Pierced structure, and described female fitting is one-time formed integrative-structure.
In a preferred embodiment of the present invention, described cylindrical body is provided with screw thread at Pierced structure place.
In a preferred embodiment of the present invention, described concave structure is an arc-shaped concave structure.
In a preferred embodiment of the present invention, described smooth flat structure and Pierced structure connecting part are provided with a chamfering one, and chamfer radius is 1mm.
In a preferred embodiment of the present invention, described concave structure and Pierced structure connecting part are provided with a chamfering two, and chamfer radius is 3mm.
In a preferred embodiment of the present invention, described chamfering two two ends are also respectively arranged with a circular arc tangent plane.
In a preferred embodiment of the present invention, described female fitting is a symmetrical structural member.
The invention has the beneficial effects as follows: female fitting of the present invention by arc-shaped concave structure and other with it the component of arc-shaped concave structure matching fit tightly, occupy little space, effective, this product adopts powder metallurgy one-shaping technique, easy to process, product performance are stable, and mechanical strength is high, and cost is low.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the embodiment of the present invention, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also according to these accompanying drawings, obtain other accompanying drawing, wherein:

Fig. 2 is the plan view of a preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, cylindrical body, 2, smooth flat structure, 3, concave structure, 4, Pierced structure.
Embodiment
Below the technological scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Embodiment based in the present invention, those of ordinary skills, not making all other embodiments that obtain under creative work prerequisite, belong to the scope of protection of the invention.
A kind of female fitting, as depicted in figs. 1 and 2, described female fitting is cylindrical body 1 structure, one end of described cylindrical body 1 is smooth flat structure 2, the other end of described cylindrical body 1 is the concave structure 3 that two ends upwarp, described female fitting center is a Pierced structure 4, and described female fitting is one-time formed integrative-structure.
Further, described cylindrical body 1 is provided with screw thread at Pierced structure 4 places.
Further, described concave structure 3 is an arc-shaped concave structure.
Further, described smooth flat structure and Pierced structure connecting part are provided with a chamfering one, and chamfer radius is 1mm.
Further, described concave structure and Pierced structure connecting part are provided with a chamfering two, and chamfer radius is 3mm.
Further, described chamfering two two ends are also respectively arranged with a circular arc tangent plane.
Further, described female fitting is a symmetrical structural member.
This female fitting is by the component laminating of arc-shaped concave structure matching is fixing with it with other, and is fixed by screw thread.
The beneficial effect of female fitting of the present invention is: female fitting of the present invention by arc-shaped concave structure and other with it the component of arc-shaped concave structure matching fit tightly, occupy little space, effective, this product adopts powder metallurgy one-shaping technique, easy to process, product performance are stable, and mechanical strength is high, and cost is low.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
