Abstract
The invention discloses a rubidium, iron and boron magnetic steel forming mold which comprises an upper mold and a lower mold. The upper mold and the lower mold are arranged among an upper pressure bar, a lower pressure bar and a forming female mold, and both the upper mold and the lower mold are made of hard alloy materials. Compared with the prior art, the rubidium, iron and boron magnetic steel forming mold has the advantage that problems of high cost, short service life, long shutdown mold changing time, low product percent of pass, low production efficiency and the like of an existing rubidium, iron and boron magnetic steel forming mold can be solved.
Description
Technical field
The present invention relates to the Machining Technology field, especially a kind of mould of processing rubidium iron boron magnet steel.
Background technology
Existing rubidium iron boron magnetic material or the multiplex nonmagnetic steel mould of bar magnet are compressing; the hardness of this mould is lower; wearability is relatively poor; under operating pressure; easily distortion; the problems such as easily wearing and tearing, thereby die cost are high, service life is short, shut down that mould replacing time is long, product percent of pass is low and production efficiency is low.
Summary of the invention
The problems such as problem to be solved by this invention provides a kind of rubidium iron boron magnet steel mould, and it can improve, and existing rubidium iron boron magnet steel mould cost is high, service life is short, shut down that mould replacing time is long, product percent of pass is low and production efficiency is low.
In order to address the above problem, technical scheme of the present invention is: this rubidium iron boron magnet steel mould comprises the upper die and lower die that are arranged between upperpush rod and down-pressed pole and the shaping female mold, and the material of described patrix and described counterdie is carbide alloy.
In the technique scheme, more specifically scheme can be: described carbide alloy is made by the percentage by weight of following component: the nickel powder 18.5%～20% of 2.5～3 μ m, surplus are the tungsten carbide of 3～5 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 19.5% of 2.5～3 μ m, surplus are the tungsten carbide of 3～5 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 15%～18% of 2.5～3 μ m, surplus are the tungsten carbide of 1～3 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 17.5% of 2.5～3 μ m, surplus are the tungsten carbide of 1～3 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 24%～25.5% of 2.5～3 μ m, surplus are the tungsten carbide of 4～5 μ m.
Further: described Hardmetal materials is made by the percentage by weight of following component: the nickel powder 25% of 2.5～3 μ m, surplus are the tungsten carbide of 4～5 μ m.
Owing to adopted technique scheme, the present invention compared with prior art has following beneficial effect:
The upper die and lower die of this rubidium iron boron magnet steel mould adopt carbide alloy to make, hardness, the intensity index of mould are improved, make under the pressure that rubidium iron boron magnet steel continued in whole forming process, the characteristic that magnetic steel die is wear-resisting has improved the working (machining) efficiency of magnet steel; Rubidium iron boron magnet steel qualification rate after the moulding is significantly improved, has also improved the compactness of magnet steel simultaneously, make magnet steel in use be difficult for bursting apart, and the fineness on magnet steel surface also significantly improves, guaranteed the performance requirement of rubidium iron boron magnet steel.For example: the mould that originally used general nonmagnetic steel material to make, its hardness are about HRC40～50, and wearability is relatively poor, and in about 5～6 days of service life, product percent of pass is 80%, and goes up easily magnetic; After using the present invention, the mould that the non-magnesium hard alloy of low Binder Phase is made, its hardness is greater than HRA87, and wearability spy is good, and fragility is bigger than normal, can not go up magnetic, extends to service life about 15 days, and product percent of pass is 90%; The mould that the non-magnesium hard alloy of high Binder Phase is made, its hardness is greater than HRA79, and wearability is fine, and toughness is high, and can reach about 10 months service life, can not go up magnetic, and product percent of pass is 95%.
