Description
Technical field
It the utility model is related to hard alloy technical field, and in particular to a kind of high-performance with multilayered and graded structure is hard
Matter alloy screw nut mould.
Background technology
Hard alloy is high rigidity, high intensity, the material of high abrasion, is obtained for extensively in the various fields of modern industry
Using.The processing of the handwares such as screw nut, usually using the mould of hard alloy material, punching press is carried out to metal wire rod, obtained
Obtain hardware.The wearability of hard alloy screw nut die-face determines the whole mold use life-span.Traditional is hard
Matter alloy screw nut mould integrally uses the Hardmetal materials of high-wearing feature, after die life terminates, the material of whole mould
Material is all scrapped, but damage in fact be only mould punching face superficial layer, mold material abandoned together,
Cause the waste of resource.
Using the technical scheme of gradient hard alloy mould, substantial amounts of hard alloy resource can be saved.Only rushed in mould
The superficial layer of pressure surface uses the Hardmetal materials of more high-wearing feature, and mold material uses the Hardmetal materials of high tenacity,
Mould stress surface hardness is high, and wearability is good, destroys toughness（Kic）Improve, and wearing layer is to the frame mode of ductile layers and hard
Spend state in gradient.Mold material has good impact flexibility.The wearability and toughness for making alloy are coordinated well,
So as to improve the combination property of hard alloy and service life, preferably solves wearability in traditional single structure hard alloy
Contradiction between toughness.But toughness material and two kinds of different material characteristics for making material base of wear-resisting compound are big, how will
Toughness material and wear-resisting compound are pressed into screw nut mould material base, it is necessary to which effective forming method could be realized.
Chinese patent CN103817150, which discloses a kind of gradient-structure type carbide roll ring, includes collars outer layer and collars
Core, the configuration of collars outer layer is in the outer surface of collars core, in collars outer layer with there is mutual crucible zone between collars core, outside collars
The composition of forming component gradient between layer and collars core, collars outer layer and collars core is different, will mix the dried collars of wax
Outer layer ball mill mixing and the dried collars core ball mill mixing place Min layers closed assembly powder of wax is mixed, cold moudling be collars blank, is passed through
Sintering obtains final products.It only has component gradient the disadvantage is that, the collars structure of the technical scheme in the radial direction of collars,
Collars upper and lower surface does not have wearing layer, and face up cut shear when collars uses can apply release effect to the interface of radial direction composition,
Cause collars restricted lifetime.In consideration of it, this patent proposes a kind of high-performance carbide screw spiral shell with multilayered and graded structure
Hat cone has.
Utility model content
The purpose of this utility model is to provide a kind of high-performance carbide screw nut with multilayered and graded structure
Mould, concrete technical scheme are：
A kind of high-performance carbide screw nut mould with multilayered and graded structure, comprising toughness material matrix and wear-resisting
The bed of material, the toughness material matrix have central through hole structure, and the wear-resisting bed of material is arranged at the surface of the through-hole structure, described
The wear-resisting bed of material is also disposed on the upper surface of the toughness material matrix.
The wear-resisting bed of material for being arranged at central through hole body structure surface, its thickness are no more than the central through hole structure radius
Half.
The technical solution of the utility model has the following advantages that：
Toughness material matrix has good impact flexibility, and wear-resisting bed of material hardness is high, and wearability is good, leads to by the center of being arranged at
The wear-resisting bed of material on pore structure surface, realizes the machining function of screw nut mould, while is arranged at the resistance to of toughness material matrix surface
Abrasive material plays a protective role to interface between layers below, has the Talide screw spiral shell of sandwich construction
Hat cone tool saves wear-resistant material layer material, long lifespan.
Brief description of the drawings
The high-performance carbide screw nut mould that Fig. 1 the utility model embodiments have multilayered and graded structure is illustrated
Figure.
Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Fig. 1 is refer to, a kind of high-performance carbide screw nut mould with multilayered and graded structure, includes toughness material
Matrix 4 and the wear-resisting bed of material, the toughness material matrix 4 have central through hole structure 10, and the wear-resisting bed of material 92 is arranged at described logical
The surface of pore structure 10, the wear-resisting bed of material 91 are also disposed on the upper surface of the toughness material matrix 4, the wear-resisting bed of material 92 and
To the hardness distribution gradient of the toughness material matrix 4, i.e. hardness is distributed the hardness of the wear-resisting bed of material 91 from high to lower.
The wear-resisting bed of material 92 for being arranged at the surface of central through hole structure 10, its thickness are no more than the central through hole structure
The half of 10 radiuses.
The wear-resisting bed of material 91 for being arranged at the upper surface of toughness material matrix 4, its thickness, which is more than, is arranged at the table of through-hole structure 10
The thickness of the wear-resisting bed of material 92 in face.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
