Abstract
The utility model provides a cone-shaped sliced assembly type wire-drawing die which comprises a die core, a die core base sleeved on the outer contour of the die core, and an upper die core cover connected with the die core base and used for locking the die core. The wire-drawing die is characterized in that the die core is formed by tightly gluing at least two pieces of fan-shaped sub-die cores; the outer counter of the die core is in a cone frustum shape; the inner chamber of the die core base is in a conical bore shape which corresponds to the shape of the outer counter of the die core; and the inner side of the upper die core cover props against the large diameter end of the cone-frustum-shaped die core when being locked. According to the wire-drawing die, the outer counter of the die core and the inner chamber of the die core base adopt the cone shape design, and the gap between sliced dire cores is reduced, so that the die core is uneasy to crack, the wire-drawing die is stable in hole shape and convenient to maintain and process; and the wire-drawing die needs no thermal bushing, so that the energy is saved and the emission is reduced.
Description
Technical field
It is the mould of various cross sectional shapes that the utility model relates to the tinsel drawing deformation, refers to particularly a kind of taper burst assembly type wire-drawing die.
Background technology
Wire-drawing die is most important a kind of instrument in the tinsel process, and its Main Function is that tinsel is passed through nib under external force by force, makes compressed diameter or the shape that is deformed into expection of tinsel sectional area.Wire-drawing die mainly adopts high rigidity, the high abrasion resisting materials such as diamond, tungalloy to make, but this material rareness and price are high.And, the general fragility of this material is higher, therefore also to carry out certain processing to it: high rigidity, the general core rod that manufactures in batches of high abrasion resisting material, then with its hot embedding or cold pressing and be embedded in the carbon steel overcoat that turning processes, so both can allow the carbon steel overcoat solve easily crisp broken defective of core rod to the certain compression of core rod, can save again the cost of high rigidity, high abrasion resisting material reduction wire-drawing die.Core rod also can adopt the burst package assembly, and its center nib part is then according to drawable material and the processing of shape specialized designs thereof.
Yet core rod adopts the wire-drawing die of burst package assembly to produce easily following problem: one, carbon steel overcoat are not easy to the core rod compression, cause the crisp broken probability of core rod to strengthen; Its two, can give the core rod external support force during tinsel drawing deformation, the burst assembling core rod gap of combining closely is strengthened; Its three, the core rod of burst assembling produces vertically dislocation easily in drawing process, cause the wire-drawing die pass to change, and then mould was lost efficacy; Its four, stop up easily nib in the soft metal coating steel wire drawing process, unitary mould must be cut off processing in this case, silk thread is cut off and is caused wire length not enough, causes waste.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of core rod to be difficult for crisp broken, processing is stablized, is convenient to safeguard to die draft taper burst assembly type wire-drawing die.
For achieving the above object, the taper burst assembly type wire-drawing die that the utility model is designed, comprise core rod, be set in the core rod base on the core rod outline and link to each other with the core rod base and be used for the core rod loam cake of locking core rod, its special character is: described core rod is fitted tightly by at least two fan-shaped submodule cores and forms, and its outline is truncated cone; The inner chamber of described core rod base is the circular cone hole shape, and is corresponding with the outer contour shape of core rod; The inboard of described core rod loam cake is connected to the larger diameter end of truncated cone core rod under locking state.
As preferred version, the cone angle B=15 of the truncated cone outline of described core rod ~ 20 °, the cone angle of the circular cone hole shape inner chamber of described core rod base is complementary with it.Cone angle is 15 ~ 20 °, and this angle is the self-locking angle, and under the effect of pulling capacity, base is to add main trend to the compression of core rod.
As preferred version, link to each other by the locating dowel that is arranged in its locating hole between the described fan-shaped submodule core, can avoid the multi-disc core rod to produce vertically dislocation.
Further, link to each other by internal and external threads between described core rod loam cake and the core rod base.
Further, be respectively arranged with the erecting tools jack on described core rod loam cake and the core rod base, available rod tool utilizes the erecting tools hole that loam cake is thoroughly compressed core rod.
The utility model has the advantage of: core rod profile of the present utility model adopts conical design, and the gap that conical design has reduced between the burst core rod adds Risks; The special-shaped mould that is difficult to whole processing adopts the burst attrition process more convenient; Mould does not need to carry out heat edge cover, energy-saving and emission-reduction; In addition, the utility model is intended repairing in the property drawing process at zinc-coated wire and is used, be conducive to that the die entrance end piles up that zinc sticks together and nib in silt zinc up cleaning, the steel wire of breaking when avoiding above-mentioned situation occurring causes the short chi of steel wire.

Fig. 2 is the A-A sectional structure schematic diagram of Fig. 1.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the utility model comprises core rod 2, be set in the core rod base 1 on core rod 2 outlines and link to each other with core rod base 1 and be used for the core rod loam cake 3 of locking core rod 2, described core rod 2 is fitted tightly by two fan-shaped submodule core 2a and forms, and its outline is truncated cone; The inner chamber of described core rod base 1 is the circular cone hole shape, and is corresponding with the outer contour shape of core rod 2; The inboard of described core rod loam cake 3 is connected to the larger diameter end of truncated cone core rod 2 under locking state.The cone angle B=15 of the truncated cone outline of described core rod 2 ~ 20 °, the cone angle of the circular cone hole shape inner chamber of described core rod base 1 is complementary with it.Cone angle is 15 ~ 20 °, and this angle is the self-locking angle, and under the effect of pulling capacity, it is to add main trend that core rod base 1 is given the compression of core rod 2.Link to each other by the locating dowel 4 that is arranged in its locating hole between the described fan-shaped submodule core 2a, can avoid fan-shaped submodule core 2a to produce vertically dislocation.Link to each other by internal and external threads between described core rod loam cake 3 and the core rod base 1.Be respectively arranged with erecting tools jack 5 on described core rod loam cake 3 and the core rod base 1, available rod tool is inserted in it core rod 2 is compressed.
Need to be under the prerequisite of not cutting off steel wire in the drawing process Steel Wire Surface be processed or when changing core rod 2; shut down first; afterwards a little reversing of drawing reel drum is made the silk thread of drawing lax; afterwards mould is proposed in the lump together with steel wire in diaphragm capsule; unclamp the assembling mould and can carry out the Steel Wire Surface processing or change core rod 2, again mould is assembled afterwards postposition and entered diaphragm capsule continuation drawing.
