Description

The wire-drawing die and die sleeve of anti-dropout

Technical field

The utility model relates to the manufacturing fields of wire-drawing die, and in particular to a kind of wire-drawing die and die sleeve of anti-dropout.

Background technique

Currently, the core bore of conventional diamond wire-drawing die stainless steel or brass die sleeve is the cylindrical empty of smooth-sided compression candles Gap, this wire-drawing die is in cracking wire drawing speed of production or very hard wire drawing metal material, since die sleeve is to burning The package scarce capacity of knot body often will appear the phenomenon that sintered body falls off from die sleeve core bore, lead to scrapping for mold.

Utility model content

The main purpose of the utility model is to provide a kind of wire-drawing die of anti-dropout and die sleeves, solve wire-drawing die and exist The phenomenon that die sleeve is to the package scarce capacity of sintered body during production, and caused die sleeve core bore falls off.

A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: wire drawing die cover of anti-dropout, Die sleeve mould material is one of medium carbon steel, carbon tool steel or high-carbon iron, and die sleeve is open inner wall equipped with groove.

In preferred embodiment, groove is helicla flute, or is annular groove.

In preferred embodiment, trench cross section shape is rectangular, triangle, trapezoidal or semicircle.

In preferred embodiment, groove number arrives multiple for 1.

In preferred embodiment, the ratio between trench depth and die sleeve outer circle ring thickness are 1 ~ 10:20.

In preferred embodiment, it is equipped with mold core in die sleeve, sintered powder is filled between mold core and die sleeve, in mold core, powder The wire drawing mouth of perforation is equipped in the middle part of sintered body and die sleeve, mold core material is diamond, artificial diamond, PCD diamond, CVD monocrystalline gold One of hard rock or polycrystalline diamond, the outer wall inclination of mold core, die sleeve Way in are relatively large in diameter, and die sleeve export direction is straight Diameter is smaller, and die sleeve mould material is one of medium carbon steel, carbon tool steel or high-carbon iron, and die sleeve is open inner wall equipped with groove.

In preferred embodiment, groove is helicla flute, or is annular groove.

In preferred embodiment, groove number arrives multiple for 1.

The utility model provides the wire-drawing die and die sleeve of a kind of anti-dropout, is provided with by using on die sleeve opening inner wall Multiple grooves, increase with the contact area of sintered powder, improve die sleeve to the package ability of sintered powder, prevent mold core from The phenomenon that falling off in sintered body increases contact area in mold core outlet by the way of bevel edge, when wire-drawing die is using When, bevel edge structure can bear higher impact force, improve the service life of wire-drawing die.

Specific embodiment

As shown in Fig. 1 ~ 6, a kind of wire drawing die cover of anti-dropout, die sleeve (1) mould material is medium carbon steel, carbon tool steel or height One of carbon iron, die sleeve (1) are open inner wall equipped with groove (5), and thus structure, die sleeve (1) opening inner wall are equipped with groove (5), The phenomenon that die sleeve 1 is improved to the package ability of sintered powder 4, prevents mold core 2 from falling off out of sintered body 4.

In preferred embodiment, groove (5) is helicla flute, or is annular groove, thus structure, a variety of preferred embodiments, according to making Difference selects then groove (5).

In preferred embodiment, groove (5) cross sectional shape is rectangular, triangle, trapezoidal or semicircle, and thus structure, a variety of Preferred embodiment selects the shape of then groove (5) according to the difference used, as shown in Fig. 4 ~ 6.

In preferred embodiment, groove (5) quantity is 1 to multiple, and thus structure, then groove is selected according to the difference used (5) quantity.

In preferred embodiment, the ratio between groove (5) depth and die sleeve (1) outer circle ring thickness are 1 ~ 10:20, and thus structure, most deep Depth be outer circle ring thickness half.

In preferred embodiment, mold core (2) are equipped in die sleeve (1), sintered powder is filled between mold core (2) and die sleeve (1) (4), the wire drawing mouth of perforation is equipped in the middle part of mold core (2), sintered powder (4) and die sleeve (1), mold core (2) material is diamond, people One of work diamond, PCD diamond, CVD single-crystal diamond or polycrystalline diamond, the outer wall inclination of mold core (2), die sleeve entrance (3) direction is relatively large in diameter, and it is smaller that die sleeve exports (7) orient diameter, die sleeve (1) mould material be medium carbon steel, carbon tool steel or One of high-carbon iron, die sleeve (1) are open inner wall equipped with groove (5).

In preferred embodiment, groove (5) is helicla flute, or is annular groove.

In preferred embodiment, groove (5) cross sectional shape is rectangular, triangle, trapezoidal or semicircle.

In preferred embodiment, groove (5) quantity arrives multiple for 1.

In preferred embodiment, the ratio between groove (5) depth and die sleeve (1) outer circle ring thickness are 1 ~ 10:20.
