Abstract
A manufacturing process of premould of metal wire drawing mould comprises steps: a) preparing filling materials according to a prescription; b) weighing the filling materials; disposing a diamond in the center of a metal mould sleeve, filling the filling materials, capping and sealing firmly; d) heating and pressing for certain time on the hot pressing sintering machine; e) naturally cooling to the normal temperature to obtain the premould of the diamond wire drawing mould. The invention has advantages that the intensity of the sintered filling materials is obviously enhanced compared to the prior art, because of adopting the filling materials prepared by the new prescription, the hardness HRB of the sintered filling materials can reach 108-116, so that the anti-impact force of the metal wire drawing mould manufactured thereby is reinforced, the cracking and bursting caused by insufficient intensity of the sintered filling material mixture and generated during drawing a rigid wire of the metal wire drawing mould can be avoided effectively, the service life of the metal wire drawing mould can be increased, the production cost of the wire producing manufacturer can be saved, and theproduct quality can be improved.
Description
Technical field
The invention belongs to metal material moulding and make field, particularly a kind of manufacturing process of premould of metal wire drawing mould.
Background technology
The pre-die manufacturing process of metal wire rod wire-drawing die of the prior art is so mostly: in the center of a metal die sleeve, set and do the diamond that nib is used, powder by multiple material, mix according to certain proportioning, the mixture of making is an inserts, is filled in the metal die sleeve, add a cover and secure, it is placed on the sintering machine, and the pressurization several minutes of heating can be finished after the cooling at random.But the present inserts that uses, because its contained material and proportioning thereof are improper, the pre-mould that behind oversintering, obtains, the tensile strength of the inserts mixture behind the sintering wherein is not enough, hardness HRB is roughly between 78～86, anti-impact force is very poor, make with this metal wire rod wire-drawing die of making in drawing process, the high strength extruding force that produces by drawing, make sintered body partly be out of shape, extend out easily, make mould in hard silk pulling process, cause cracking, explosion easily, can not reach the perfect condition of rigid line drawing.Like this, not only frequent output waster, and also mould therefor is fragile, has increased production cost.
Summary of the invention
Technical problem to be solved by this invention is the manufacturing process that a kind of tensile strength height, not yielding, the premould of metal wire drawing mould that is difficult for extending out are provided at above-mentioned prior art present situation.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: a kind of manufacturing process of pre-mould of metal wire rod wire-drawing die, it is characterized in that, and may further comprise the steps:
A) the inserts needed raw material is equipped with according to following prescription: below count by weight percentage: nickel 30～34%; Copper 17～20%; Manganese 7～9%; Tin 19～22%; Silver 3～5%; Tungsten 7～9%; Zinc 3～5%; Silicon 1～2%; Above-mentioned various materials are made powder, re-use mixer and carry out repeatedly stirred for several hour, make it to mix;
B), that is, weigh the inserts of obtaining among the step a that gets some that mixes in the balance according to the specification of metal die sleeve according to the specification of premould of metal wire drawing mould to be processed;
C) diamond is placed metal die sleeve center, insert inserts, add a cover and secure, obtain a premould of metal wire drawing mould to be formed;
D) with the premould of metal wire drawing mould to be formed among the step c, place in the graphite jig, add the graphite pressure head, be put on the hot pressed sintering machine, add temperature to 580～600 degree Celsius, 4～5 atmospheric pressure of plus-pressure kept 10～15 minutes;
E) the hot pressed sintering machine withdraws from the sintering program, and premould of metal wire drawing mould naturally cools to 370～390 degree Celsius at random, and the hot pressed sintering machine is finished all programs, take out graphite jig, naturally cool to normal temperature, open graphite jig, take out the pre-mould of diamond wire-drawing die of moulding.
As preferably, the basic composition of the prescription of the inserts among the manufacturing technology steps a of above-mentioned premould of metal wire drawing mould is as follows: below count by weight percentage: nickel 34%; Copper 19%; Manganese 8%; Tin 21%; Silver 4%; Tungsten 8%; Zinc 4%; Silicon 2%.
As preferably, the basic composition of the prescription of the inserts among the manufacturing technology steps a of above-mentioned premould of metal wire drawing mould is as follows: below count by weight percentage: nickel 32%; Copper 19%; Manganese 8%; Tin 20%; Silver 5%; Tungsten 9%; Zinc 5%; Silicon 2%.
As preferably, the temperature among the manufacturing technology steps d of above-mentioned premould of metal wire drawing mould is 590 degree, and pressure is 4.5 atmospheric pressure, and the retention time is 12 minutes; Temperature among the step e is 380 degree.
Compared with prior art, the invention has the advantages that, because the inserts of the new prescription that it uses, the obvious enhancing of the prior art of strength ratio behind the sintering, its hardness HRB can reach 108-116, make and strengthen with the anti-impact force of this metal wire rod wire-drawing die of making, can effectively avoid the metal wire rod wire-drawing die in the pulling process of hard silk, to produce, because the cracking that insufficient strength caused and the explosion of the inserts mixture behind the sintering, increased the service life of metal wire rod wire-drawing die greatly, producer has saved production cost for wire production, has improved the quality of its product.
