Description
Technical field
The utility model belongs to crusher cutter technical field, and in particular to a kind of titanium alloy titanium sponge crushing cutter.
Background technique
Currently, crusher most common problem in crushing sponge titanium is: 1, steel cutter unavoidably causes steel cutter
In iron pollution titanium sponge, cause in titanium sponge finished product that ferro element is exceeded, the plasticity of titanium processing finished product caused to be deteriorated；2, due to knife
It is complicated to have service condition, common steel cutter easily corrodes, and causes decreased tool life, and often repair and change the outfit cutter,
Cause equipment downtime, can not normal use, to reduce equipment service efficiency；3, blade local damage leads to entire cutter report
It is useless, increase maintenance cost.Moreover, the cutter head of existing crusher cutter is easy passivation after use, also increase
Machine utilization causes unnecessary energy loss.
Utility model content
The utility model solves the deficiencies in the prior art, provides that a kind of service life is long, a kind of titanium alloy of highly corrosion resistant
Titanium sponge crushing cutter, removable installation blade, easy to change on titanium alloy cutter head, further extends the use of the stage property
Service life.
The technical scheme adopted by the utility model is a kind of titanium alloy titanium sponge crushing cutter, including cutter body, institute
Stating cutter body is cylindrical structure, and it is made of titanium alloy material, and described cutter body one end is provided centrally with positive six side
Shape cavity, the other end are provided with titanium alloy cutter head, and the titanium alloy cutter head is hemispherical dome structure, are provided in the cutter body
U-shaped deflector hole is equidistantly equipped with several removable blades on the titanium alloy cutter head.
Preferably, the blade is made of integrally formed titanium alloy bit and screw rod, and the blade passes through its screw rod
It is arranged in titanium alloy cutter head.
It is further preferred that the titanium alloy bit is circular cone structure, surface is provided with semi-circular recesses, described
Semi-circular recesses spiral is set to titanium alloy blade head surface.
Compared to the prior art, the utility model has the advantages that the utility model cutter body using high temperature resistant
The titanium alloy material of property and corrosion resistance is made, and deflector hole is provided in titanium alloy cutter head, plays the role of cooling to cutter head, is made
Cutter head works within the scope of a stationary temperature, further extends the service life of its cutter, removable on titanium alloy cutter head
Blade is installed, it is convenient to change, and can replace when single breaks down, service work is not only alleviated, but also improve work efficiency,
Also reduce cost.
Detailed description of the invention
Fig. 1 is the utility model cutter structure cross-sectional view；
Fig. 2 is the utility model cutter right view；
Fig. 3 is the utility model blade structure schematic diagram.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of titanium alloy titanium sponge crushing cutter, refering to fig. 1, Fig. 2 and Fig. 3, including cutter body 4, the cutter body 4
For cylindrical structure, and it is made of titanium alloy material, has good heat-resisting quantity and corrosion resistance, the cutter body 4
One end is provided centrally with regular hexagon cavity 5, and the other end is provided with titanium alloy cutter head 2, and the titanium alloy cutter head 2 is hemispherical junction
Structure is provided with U-shaped deflector hole 3 in the cutter body 4, in order to not only alleviate service work, but also improves work efficiency, also drop
Low cost is equidistantly equipped with several removable blades 1 on the titanium alloy cutter head 2.Currently, being used in crushing sponge titanium
Steel cutter unavoidably causes the iron pollution titanium sponge in steel cutter, causes ferro element in titanium sponge finished product exceeded, to make
It is deteriorated at the plasticity of titanium processing finished product；If the tensile strength of special titanium alloy is more than or equal to special titanium alloy cutter
500MPa, elongation percentage are more than or equal to 20%, and hardness HRC is less than or equal to 35, and titanium sponge production producer is in broken bulk sponge at present
Steel cutter when titanium is generally high-speed steel, its tensile strength is more than or equal to 1000MPa, and elongation percentage is more than or equal to 15%,
Hardness HRC is less than or equal to 53, and its wearability is very poor, it is clear that does cutter material and is not suitable for；So a kind of its cooperation of titanium alloy
Than as follows: Ti surplus, AL3.5-4.4%, V3.5-4.5%, Mo7.2-8.2%, Cr4.5-5.6%, Zr0.8-1.2%,
Nb0.7-1.8%, Si0.2-0.35%, C0.08%, N0.06%, O0.2%, H0.015%) afterwards tensile strength be more than or equal to
1500MPa, elongation percentage are more than or equal to 10%, and hardness HRC is less than or equal to 55, it is clear that making cutter with the titanium alloy is optimal selection.
Refering to fig. 1 and Fig. 3, the blade 1 are made of integrally formed titanium alloy bit 6 and screw rod 8, the blade 1
It is arranged in titanium alloy cutter head 2 by its screw rod 8.This blade with screw rod greatly facilitates the replacement of cutter head.
Refering to Fig. 3, the titanium alloy bit 6 is circular cone structure, and surface is provided with semi-circular recesses 7, described half
7 spiral of circular groove is set to 6 surface of titanium alloy bit.The groove blade of spiral setting, increases the corner angle area of blade,
Keep stock-removing efficiency better.
The titanium alloy preparation method: by melting out spindle in vacuum melting furnace after above-mentioned nominal composition ingredient, then titanium
Alloy pig forges above-mentioned specification on forging machine, then keeps the temperature 5 hours by 430 degree of air-cooled annealing in heat preservation 16 hours and 460 degree
Quenching heat treatment reaches good comprehensive energy.
Above-described embodiment, the only preferred embodiment of the utility model not are used to limit the implementation model of the utility model
It encloses, therefore all equivalent variationss done with content described in the utility model claims, the utility model right should all be included in and wanted
Within the scope of asking.
