The utility model overcomes the defects that a die core of the existing diamond die is easy to slide off from a hard alloy die sleeve in the process of wiredrawing, improves the service life of a wiredrawing die, and is suitable for metal wiredrawing industry.
Description
Technical field
The utility model relates to the diamond wire-drawing die that is used for metal wire drawing, especially relates to a kind of carbide alloy that has that can prevent effectively that polycrystalline diamond comes off in the drawing process and supports polycrystalline diamond mould base.
Background technology
Diamond wire-drawing die is a kind of metal wire rod is drawn into the size homogeneous, is met the mould of the filament of productive life demand by size and crin blank in irregular shape.Its major part is the diamond wire drawing die blank in centre, is processed with the aperture with certain physical dimension at this mould base center and is used for the drawing metal wire rod.As required, polycrystalline diamond wire drawing die mould base comprises that no carbide alloy supports polycrystalline diamond mould base and has carbide alloy support polycrystalline diamond mould base.The latter can bear bigger pulling force, is used for making the large aperture wire drawing die more, the wire rod that the drawing diameter is thicker.At present, traditional polycrystalline diamond core rod that has in the carbide alloy support polycrystalline diamond mould base is a cylindrical product synthetic under HTHP, this cylindrical polycrystalline diamond core rod is mounted to and just can obtains having carbide alloy in the carbide alloy die sleeve and support polycrystalline diamond mould base, carries out following process again and obtains the polycrystalline diamond wire drawing die tool.This cylindrical polycrystalline diamond core rod not only can improve withstand load power, and stress distribution is even, even at abominable condition of work counterdie base also easy fracture not.But the cylindrical polycrystalline diamond mold insert structure of this kind makes that in drawing process the polycrystalline diamond core rod in the diamond wire drawing die blank is subjected to the external carbuncle effect and landing from the carbide alloy die sleeve easily, to cause the life-span reduction of diamond wire-drawing die.
The utility model content
In order to overcome existing diamond wire-drawing mold core is easy to landing from the carbide alloy die sleeve in drawing process deficiency, the utility model provides a kind of carbide alloy that has with new structure to support polycrystalline diamond mould base, this mould base has effectively stoped the landing of diamond wire drawing die core, the life-span of having improved wire-drawing die.
For achieving the above object, the utility model by the following technical solutions:
Diamond wire drawing die blank of the present utility model, the polycrystalline diamond core rod that comprises carbide alloy die sleeve and this die sleeve of embedding, the wire drawing through hole is set on the core rod, has at least a cross section not overlap in the arbitrary section perpendicular to wire-drawing direction of described core rod in projection perpendicular to the projection on the plane of wire-drawing direction and other cross section.
Further, described core rod is a cylinder, and the wire drawing through hole is arranged on the cylinder center; This cylinder is the circle drum cylinder of side evagination, perhaps is the cylinder of side indent, perhaps is the scraggly cylinder in side.
Further, described core rod is a bullet, and the wire drawing through hole is arranged on the center of bullet, and the big end of this bullet surface area is as wire inlet end, and the other end is as wire outlet end.
Further, the end face of described bullet is a kind of shape in triangle, quadrangle, pentagon, hexagon or the octagonal, and its side is an antiparallelogram.
The beneficial effects of the utility model are: diamond core rod of the present utility model can directly obtain by the sintering of diamond particles under the HTHP (diadust) and binding agent (being generally the Co powder).Afterwards, the diamond core rod that these is had a given shape structure is embedded in and obtains having carbide alloy in the carbide alloy die sleeve and support polycrystalline diamond mould base.Subsequently, on the diamond wire drawing die blank material, bore technologies such as wire drawing hole, sizing, polishing with processing methods such as laser, electric sparks again, obtain needed polycrystalline diamond wire drawing die tool.The cross section of core rod with the requirement of the utility model ad hoc structure is not of uniform size, and core rod can be embedded in the carbide alloy die sleeve firmly, therefore is difficult for deviating from from the carbide alloy die sleeve.For example, for the polycrystalline diamond wire drawing die core rod of bullet, big one of diameter is the direction of silk into during use, and little one of diameter is the direction of wire vent.Carrying out along with drawing process, because carbide alloy die sleeve side and wire-drawing direction are angled, core rod is subjected to the obstruction of carbide alloy die sleeve side action power, core rod can not be drawn out from the direction of wire vent, so can be embedded in securely in the carbide alloy die sleeve, improve the service life of wire-drawing die effectively.For the polycrystalline diamond wire drawing die core rod of the similar hyperbola structure of the circle drum of side evagination, side indent, prevented the landing of diamond wire drawing die core equally owing to be subjected to the obstruction of carbide alloy die sleeve side action power, improved service life.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As embodiment contrast of the present utility model, at first introduce the structure of traditional diamond wire drawing die blank.Fig. 1 is the cutaway view with traditional diamond wire drawing die blank of cylindrical polycrystalline diamond core rod.As seen from Figure 1, traditional diamond wire drawing die blank is embedded in the carbide alloy die sleeve 3 by polycrystalline diamond core rod 2 to be formed, be equipped with centre bore 1 at the middle part of diamond core rod 2, traditional diamond wire-drawing die has cylindrical polycrystalline diamond core rod, during use, the landing from die sleeve 3 easily of described core rod 2 is to cause the life-span reduction of diamond wire-drawing die.
Below be embodiment of the present utility model.
Embodiment 1,
Fig. 2 is the cutaway view of the polycrystalline diamond wire drawing die mould base with bullet core rod in the present embodiment.As seen from Figure 2, the diamond wire drawing die blank of present embodiment is made up of carbide alloy die sleeve 3 and the polycrystalline diamond core rod 2 that is embedded in this die sleeve 3, is equipped with centre bore 1 at the middle part of diamond core rod 2, and this centre bore 1 is the wire drawing through hole.Diamond core rod 2 be bullet, this bullet is that cone is clipped the remaining frustoconical configuration of the vertex of a cone, i.e. truncated cone shape.When using, the one side that core rod 2 areas of section are bigger, is wire vent one end when the less one side of area of section is used for advancing silk one end.Core rod 2 just is not easy slippage from die sleeve 3 when using like this.Obviously, for reaching same invention effect, the core rod 2 of the frustum structure that this area of section is different can be triangular frustum, tetragonous cone table, pentagonal pyramid platform, hexagonal pyramid platform and eight frustum of a pyramids, be that its cross section is respectively triangle, quadrangle, pentagon, hexagon and octagonal, its side is antiparallelogram.
