Therefore, be necessary that the technical scheme proposing a kind of improvement solves the problems referred to above.
Utility model content
The purpose of this utility model is to provide a kind of cold extrusion mould of abnormity band reinforcement shape pick, by using the patrix of existing general pick mould as counterdie, not only convenient location, the easily material returned, and make the stud that is shaped full, not easily produces turned-down edge.
In order to solve the problem, the utility model provides a kind of cold extrusion mould of abnormity band reinforcement shape pick, and it carries out cold extrusion for aligning the blank extruding stud, and it comprises:
Counterdie, it is formed with the first lower mode cavity and the second lower mode cavity, and described first lower mode cavity is communicated with described second lower mode cavity, and the counterdie accent at the interior described counterdie top without leave of described first lower mode cavity successively decreases to the second lower mode cavity;
Patrix, it is positioned at the top of described counterdie, and described patrix comprises drift and is positioned at the drift cover outside described drift,
During extruding, described drift is descending, and described blank is contacted completely with described ram bottom, and described drift continues to move downward to extrude blank and makes the stud of blank be full of described first lower mode cavity, the blank thick in the middle of being shaped, two ends are thin; The pick that one end has special-shaped stud, the other end has cylindrical form;
After pick is shaped, described drift is up, by stripping attachment, blank is ejected described counterdie, completes and once extrude.
As the utility model one preferred embodiment, one end of described pick is special-shaped stud structure, the other end is tubular construction, and size thick portion in the middle of described blank of described special-shaped stud structure one end reduces gradually to end.
As the utility model one preferred embodiment, the quantity of described special-shaped stud is four, and these four special-shaped studs are axially evenly distributed around it.
The beneficial effects of the utility model: compared with prior art, the utility model first utilizes positive extruding mold just to extrude stud, when being convenient to be shaped, stud is full, then the pick after just squeezing is positioned over cold extrusion mould and extrudes, structure not only convenient location, the easily material returned of the utility model cold extrusion mould, and make the stud of shaping full, not easily produce turned-down edge, not easily make head muscle class and patrix adhesion.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.Wherein:

Detailed description of the invention
For enabling above-mentioned purpose of the present utility model, feature and advantage become apparent more, are described in further detail the utility model below in conjunction with the drawings and specific embodiments.
Alleged herein " embodiment " or " embodiment " refers to special characteristic, structure or the characteristic that can be contained at least one implementation of the utility model.Different local in this manual " in one embodiment " occurred not all refers to same embodiment, neither be independent or optionally mutually exclusive with other embodiments embodiment.
Refer to Fig. 2 to Fig. 3, Fig. 2 is the forming technology figure of the utility model abnormity band reinforcement shape pick; Fig. 3 is the structural representation of the utility model abnormity band reinforcement shape pick die assembly.As shown in Fig. 2 to 3, the manufacturing process of described abnormity band reinforcement shape pick, is characterized in that: it comprises the steps:
S1, provide a cylindrical bar.Refer to Fig. 2 (a).
S2, base is carried out to bar obtain the bevelled blank of two ends tool, refer to Fig. 2 (b).
S3, adopt positive extruding mold to blank just squeezing to one end, there is stud, blank that the other end is tubular construction; Refer to Fig. 2 (c).
S4, blank is inverted in shaping dies and carries out cold extrusion and obtain abnormity band reinforcement shape pick 100, refer to Fig. 2 (d).
In one embodiment, after described step S1, also annealing process is comprised before S2.
In one embodiment, after described step S2, ball blast, phospholeum metallization processes is also comprised before S3.
In above-mentioned steps S3, the quantity of described stud is four.Described four studs longitudinally extend along blank from one end of described blank in the middle of blank.Described four studs are evenly distributed around the radial direction of blank.
The utility model also comprises the mould for cold-extruded in step S4, and described mould comprises counterdie 2 and patrix 3.
Described counterdie 2, it is formed with the first lower mode cavity 21 and the second lower mode cavity 22, and described first lower mode cavity 21 is communicated with described second lower mode cavity 22, and the counterdie accent at interior described counterdie 2 top without leave of described first lower mode cavity 21 successively decreases to the second lower mode cavity 22;
