Abstract
The utility model discloses a mirror polycrystalline diamond wire drawing die, which is composed of a metal casing and blank for polycrystalline diamond wire drawing dies, wherein, the middle part of the metal casing is provided with holes in which the blank for polycrystalline diamond wire drawing dies is surrounded and solidified by powder sintering bodies or soft metal. The roughness of the external plane of the blank for polycrystalline diamond wire drawing dies is more than 0.2 mu mm. The wire drawing die of the utility model has the advantages that the quality of the polycrystalline diamond wire drawing dies can be conveniently detected; the quality of the polycrystalline diamond wire drawing dies can be improved.
Description
Technical field
The utility model relates to the wire drawing die of line cable industry and makes the field, particularly relates to a kind of minute surface polycrystalline diamond wire drawing die.
Background technology
Wire drawing die be a kind of with metal wire rod by size and all irregular crin blank of shape be drawn into the size uniformity, meet that people produce or the filament of living needs must use mould.Its most important part is " core rod " in centre, the processed aperture with certain geometrical shape and size and certain surface fineness in the center of core rod.Promptly become the finished product filament behind blank crin this aperture of process or a series of aperture.
The PCD wire drawing die is with the mould product of polycrystalline diamond as core rod, it is one of polycrystalline diamond product that is most widely used on the our times, our daily life and produce in used tungsten filament in the used copper, aluminum conductor, incandescent lamp bulb, make the steel wire that spring uses, the stainless iron wire of making cleaning ball for kitchen use etc., nearly all be to draw by the PCD wire-drawing die to form.
The production process route of PCD wire-drawing mold core has two at present: a kind of is to be the simple grain pressing of representative with U.S. GE company, and its advantage is compactness and the uniformity that guarantees core material easily, but cost is higher, costs an arm and a leg, so occupation rate of market is also low.Another kind is to be large stretch of pressing of representative with DeBeers, the PCD sheet be pressed and by attrition process to the regulation thickness and surface smoothness after, adopt laser or line cutting technology to cut into the core rod of granule again.Its advantage is with low cost, therefore occupies leading position in the international market.Occur local inhomogeneous or stress cracking easily but the PCD that is pressed into is large stretch of, so need quite strict quality inspection.
Present most producer all adopts ultrasonic examination and fractographic mode the PCD wire-drawing mold core to be carried out the detection of quality, and some producer of China, even the simplest microscopic examination detects the employing of all being unwilling, and only detect by an unaided eye no big crackle or other defective are promptly sold as qualified products.In fact, for the large stretch of process route that cuts into small pieces again of compacting, the product of any company all exists the inhomogeneous or local problem such as micro-crack that contains of structure more or less, and the product of China more so." the quality instability " that causes thus, even make the PCD wire-drawing mold core product quality scale of China very high, also can't be in international and domestic acquisition price preferably.
If the PCD wire-drawing mold core is carried out the mirror finish on surface, can stop internal stress product excessive, that contain other inhomogeneous material or micro-crack effectively and come into the market, thereby improve the stability of product effectively.
If do not carry out the mirror finish on surface, microscopic examination is almost powerless to the detection of the inhomogeneous of PCD structure and micro-crack defective.Adopt ultrasonic examination, also can only detect big crackle or cavity, but can't detect internal stress and other impurity of core rod, and often whole sheet is squeezed into waster, caused great waste owing to detect local defective.Behind PCD wire-drawing mold core surperficial polished, because whole surface is smooth smooth as mirror, any small inhomogeneous or micro-crack is all with high-visible, and big internal stress also will obtain discharging in polishing process.The screened rejecting of underproof part, remaining all is qualified products naturally.Quality testing with polishing introducing wire-drawing mold core will help to improve the utilization rate and the qualification rate of product, thereby improve China PCD core rod product image in the international market greatly, make the relevant enterprise of China obtain more rich profit.
In addition, mirror finish is carried out on the surface of PCD wire-drawing mold core, also can widen its range of application.Present most diameter of section must adopt the single-crystal diamond wire drawing die to draw less than the non-ferrous metal wire of 0.05mm.In fact, requiring for surface brightness is not that very high fine wire draws, and selects for use the superfine PCD wire drawing die of diamond particles degree can be competent at too.If but the PCD wire-drawing mold core of this moment does not carry out surface finish, the observation of mould outlet position will be compared difficulty, and the application of PCD wire-drawing mold core in this field has been subjected to restriction to a certain degree thus.After PCD wire-drawing mold core surface was polished, because whole surface is smooth smooth as mirror, any small vestige all can be very easy to find.
Summary of the invention
The purpose of this utility model provides a kind of minute surface polycrystalline diamond wire drawing die.
For achieving the above object, the utility model is taked following design:
The minute surface polycrystalline diamond wire drawing die is made up of metal-coating, polycrystalline diamond wire drawing die stock, the metal-coating middle part is porose, the polycrystalline diamond wire drawing die stock is surrounded by sintered powder and is solidificated in the hole of metal-coating, or is solidificated in the hole of metal-coating by the soft metal encirclement.The roughness Ra on the appearance plane of polycrystalline diamond wire drawing die stock is more than the 0.2 μ mm.
Wire drawing die of the present utility model the utility model has the advantages that: be convenient to the quality testing of polycrystalline diamond wire drawing die, will help to improve the quality of polycrystalline diamond wire drawing die.
Description of drawings:
Fig. 1 is the utility model structural representation
The specific embodiment
Embodiment: as shown in Figure 1, the minute surface polycrystalline diamond wire drawing die is made up of metal-coating 1, polycrystalline diamond wire drawing die stock 2, and the material of metal-coating 1 is stainless steel or steel.Metal-coating 1 middle part is porose 3, and polycrystalline diamond wire drawing die stock 2 is surrounded by sintered powder 4 and is solidificated in the hole of metal-coating 1, or is surrounded by soft metal 5 and to be solidificated in the hole 3 of metal-coating 1.Handle through mirror finish on the appearance plane of polycrystalline diamond wire drawing die stock 2, makes the structural change on the appearance plane of polycrystalline diamond wire drawing die stock 2, becomes smooth minute surface by the rugged plane of microcosmic, and its roughness Ra is more than the 0.2 μ mm.Soft metal 5 can be copper product, or other Cu alloy material.Polycrystalline diamond wire drawing die stock 2 is just like the circular polycrystalline diamond wire drawing die mould base of diameter (2-40) mm, or the polycrystalline diamond wire drawing die mould base of moulding, as triangular form, four jiaos of types, five jiaos of types, hexangle type, octagon etc.Because the appearance plane of polycrystalline diamond wire drawing die stock 2 is a minute surface, so polycrystalline diamond wire drawing die mould base of moulding, be solidificated in metal-coating 1 as triangular form, four jiaos of types, five jiaos of types, hexangle type, octagon etc., can not produce wire drawing die blank loosening phenomenon in metal-coating 1.Polycrystalline diamond wire drawing die stock 2 is porose, is divided into sizing area, compressional zone, lubricated district and inlet region, outlet area etc.
