Abstract
The invention provides metal powder which can be melted and filled between a die core and a jacket to fix the die core and the jacket. The structure stability is ensured, the usage amount of diamond or corundum can be reduced, and the cost is saved.
Description
Technical field
The present invention relates to a kind of metal-powder that is used to make wortle.
Background technology
Wortle is to produce mould wiry, and the principle of work of wortle is to let thicker metal wire by force through thinner wire drawing hole, and metal wire is when passing through thinner wire drawing hole, and resistance is very big; The frictional force in metal wire and wire drawing hole is also very big, causes wortle to damage easily, for improving the work-ing life of wortle, so adopt the material of extreme hardness to process wortle; Such as diamond or corundum etc., yet these material costs are higher; For practicing thrift cost, a kind of wortle is proposed, its structure is as shown in Figure 1; Comprise: overcoat 1, wire drawing hole 2, core rod 3, coating layer 4, wherein, core rod 3 adopts diamond or corundum to process.In drawing process; When core rod 3 wall thickness are not enough, possibly cause core rod 3 to break, existing way adopts coating power material extremely strong and that toughness is extremely strong to process 4 pairs of core rods 3 of coating layer and coats; Coating layer 4 outer socket overcoats 1 are fixed; Wherein, how to select a kind of suitable material coating layer 4, very big at metal wire to wire drawing hole 2 radial pressures; And under the also very big situation of the axial friction between metal wire and the wire drawing hole 2, guarantee that are problem demanding prompt solutions the work-ing life of core rod 3.
Summary of the invention
Problem to the prior art existence; The objective of the invention is to propose a kind of metal-powder that is used to make wortle; Through a kind of metal-powder that is used to make wortle that adopts the present invention to propose; Can accomplish power consumption still less, and produce the wortle that work-ing life is higher and tolerance range is higher.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of metal-powder that is used to make wortle by weight percentage, comprises nickel 30～34%, copper 38～42%, iron 20～23%, tungsten 2～4%, tin 1～2%, molybdenum 1～2%, silver 2～3%, magnesium 1～2% and phosphorus 1～2%.
Comprise nickel 31%, copper 40%, iron 21%, tungsten 2%, tin 1%, molybdenum 1%, silver 2%, magnesium 1% and phosphorus 1%.
A kind of method of use that is used to make the metal-powder of wortle comprises the steps:
S101, between core rod and overcoat and two ends fill said metal-powder;
S102, high pressure and heat to 850 ℃～900 ℃ are to form the said metal-powder of molten state;
S103, pressurize cooling are handled the metal-powder of molten state to form metal powder layer;
S104, process said metal powder layer, form two groups of axially holes 4 of through core rods at two ends respectively;
S105, in said core rod, form the wire drawing hole.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
The metal-powder that the present invention proposes through fusing the present invention and be filled in core rod and overcoat between, can core rod and overcoat be fixed, not only guarantee structural stability, can also reduce the consumption of diamond or corundum, the saving cost.
