Abstract
The invention discloses a manufacturing process of a wire drawing die. The manufacturing process comprises the following steps of: S101, placing a die core in a die sleeve through hole; S102, filling metal powder between the die core and a die sleeve and at the two ends; S103, forming metal powder in a molten state at high temperature and under high pressure; S104, performing pressure-maintaining cooling treatment on the metal powder in the molten state to produce a metal powder layer; S105, machining the metal powder layer to form two groups of pores which axially run through the die core at the two ends respectively; and S106, forming a wire drawing hole in the die core. According to the manufacturing process of the wire drawing die, less energy consumption can be realized, and the wire drawing die with longer service life and higher accuracy can be produced.
Description
Technical field
The present invention relates to a kind of wire drawing die manufacturing process.
Background technology
Wire drawing die is to produce mould wiry; The processing of itself also is a difficult problem, if can not design an optimal scheme, it not only can more consume energy in process of production; And the accuracy of the wire drawing die of producing is not high yet; Directly having influence on the service life of final production wiry and wire drawing die, how to obtain a kind of technology of production wire drawing die of the best, is a difficult problem that needs to be resolved hurrily.
Summary of the invention
Problem to the prior art existence; The objective of the invention is to propose a kind of wire drawing die manufacturing process; Through a kind of wire drawing die manufacturing process that adopts the present invention to propose, can accomplish power consumption still less, and produce the wire drawing die that service life is higher and accuracy is higher.
For reaching this purpose, the present invention adopts following technical scheme:
A kind of wire drawing die manufacturing process comprises the steps:
S101, core rod is put into the die sleeve through hole;
S102, between core rod and die sleeve and two ends fill metal dust;
S103, HTHP form the metal dust of molten condition;
S104, pressurize cooling are handled the metal dust of molten condition to generate metal powder layer;
S105, processing metal powder bed form two groups of axially holes of through core rod respectively at two ends;
S106, in core rod, form the wire drawing hole.
Between S103 and S104, also comprise:
Heat-insulation pressure keeping makes metal dust in 3～5 minutes, keep molten condition.
Between S102 and S103, also comprise: adopt end cap to compress metal dust;
Between S104 and S105, also comprise: take off end cap.
S101 is specially: core rod is put into die sleeve through hole center.
Core rod adopts diamond or corundum to process.
In S103, need metal dust be heated to 850 ℃～900 ℃.
S106 is specially: adopt laser in core rod, to form the wire drawing hole.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
A kind of wire drawing die manufacturing process that the present invention proposes can be accomplished power consumption still less, and produced the wire drawing die that service life is higher and accuracy is higher.
Description of drawings
Fig. 1 is wherein a kind of view of the wire drawing die of the embodiment of the invention 1 processing:
Fig. 2 is the another kind of view of the wire drawing die of the embodiment of the invention 1 processing:
Wherein:
1, die sleeve; 2, metal dust; 3, core rod; 4, hole; 5, end cap; 6, wire drawing hole; 7, through hole; 8, metal powder layer.
The specific embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through the specific embodiment:
Embodiment 1
Propose a kind of wire drawing die manufacturing process, comprise the steps:
S101, core rod 3 is put into die sleeve 1 through hole 7 centers.
Die sleeve 1 adopts the chromium nickel stainless steel material to process; Core rod 3 adopts diamonds or corundum to process, and at first, on die sleeve 1, processes the through hole 7 with the spigot shaft coaxle of die sleeve 1; Then core rod 3 is placed the center of through hole 7; Leaving gap between core rod 3 and through hole 7, the axial length of core rod 3 is shorter than die sleeve 1, and does not all emerge in through hole 7 in core rod 3 two ends.
S102, between core rod 3 and die sleeve 1, fill metal dust 2, and adopt end cap 5 to compress metal dust 2.
Under S103, the high pressure conditions metal dust 2 is heated to 850 ℃～900 ℃, forms the metal dust 2 of molten condition, heat-insulation pressure keeping makes metal dust 2 in 3～5 minutes, keep molten condition.
Because metal dust 2 has certain fusing point; Metal dust 2 is heated to 850 ℃～900 ℃ melts metal dust 2; With metal dust 2 heat-insulation pressure keepings that melt; Make metal dust 2 in 3～5 minutes, keep molten condition, heat-insulation pressure keeping can make the internal state of the metal dust 2 under the molten condition even more, stable in 3～5 minutes, and was evenly distributed in more between end cap 5, core rod 3, the die sleeve 1 always.
S104, pressurize cooling are handled the metal dust 2 of molten condition with generation metal powder layer 8, and take off end cap 5.
Through reducing temperature, make that the metal dust 2 under the molten condition cools off gradually, form hard metal powder layer 8 gradually, metal powder layer 8 will be fixed on core rod 3 in the through hole 7 of die sleeve 1 tightly, takes off end cap 5.
S105, processing metal powder bed 8 form two groups of axially holes 4 of through core rod 3 respectively at two ends.
Through machining or other means, on the metal powder layer 8 that is in core rod 3 two ends, process the hole 4 of a through core rod 3, from outside to inside, the radius of this hole 4 reduces gradually.
S106, in core rod 3, form wire drawing hole 6.
Can adopt such as means such as laser, on core rod 3, form wire drawing hole 6, wire drawing hole 6 is coaxial with core rod 3.
The above; Be merely the preferable specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technical staff who is familiar with the present technique field is equal to replacement or change according to technical scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
