The invention has the beneficial effects as follows: due to adopting extrusion process, difference using the plasticity and toughness under bi-material room temperature or hot conditionss and comprcssive strength, a kind of material is made to enter the method in another kind of material matrix by pressure, simultaneously under the guarantee of pressure, consistency within matrix material is continuously increased, another kind of material of press-in can closely be wrapped, not only eliminate cavity, the defects such as crackle, eliminate potential Problem of Failure, and refinement matrix grain degree is played a role, intensity for improving matrix material simultaneously is played an important role with plasticity and toughness；Bulged-in material especially hard material is due to there being the protection of matrix material; in the case of running into chilling or anxious heat; it is slow intensification or cooling that temperature is directed into when being pressed into material; so effectively avoid the cracking of hard material it is ensured that its original physical property (as wearability)；It is achieved thereby that complex abrasion-proof product can realize various heat treatment modes, improve the wearability of matrix material, thus the overall wearability improving complex abrasion-proof product, be integrally improved the service life of final products；There is high abrasion, high impact-resistant, be applied to the complex working conditions such as high abrasion using the wear resistant products of this method manufacture, and the manufacture of the wear-resisting finished product of all kinds of shapes and specification can be realized by technology controlling and process, its Comprehensive service life can be improved for relatively conventional wear resistant products.
【Specific embodiment】
The present invention relates to a kind of extrusion molding production method of the complex abrasion-proof product of metallic matrix and hard material, comprise the steps:
A. metal matrix material prepares: the metal matrix material with build-up member is ready to, is heated to plastic temperature stand-by；This step is intended to make metal matrix material obtain preferable plasticity and toughness, possesses preferable plastic deformation and soft condition.Placement region can be provided for the cloth of hard material, can forge, by controlling the size of profile or build-up member to meet, the significant degree that hard material enters metallic matrix simultaneously.
B. hard material cloth: hard material is put into build-up member, obtains the semi-finished product of cloth honest material；Hard material refers mainly to intensity, hardness is far above the hard material of metal matrix material, and must possess anti-wear performance, the such as high-abrasive material such as diamond, pottery, cast stone, antifriction alloy.
C. molding prepares: the semi-finished product of cloth honest material are warming up to, by mode of heating, the plastic temperature that metal matrix material has plastically deformable；The forming temperature of hard material is far above the forming temperature of metal material, so the intensity of hard material and hardness keep and room temperature identical state substantially when metal material softens.
D. extrusion forming: using press device or technique to the semi-finished product extrusion forming being heated to plastic temperature, obtain complex abrasion-proof product.Metal matrix material is made completely to wrap hard material using applying pressure；Stress control is in the range of the comprcssive strength of hard material；Can by pressurized equipment stroke control extruding force to be applied to the dynamics on semi-finished product it is ensured that hard material will not be because being crushed by larger extruding force；Can also realize by forging die that forging hammer is spacing, forge dynamics to realize controlling being applied on semi-finished product.
Metal matrix material described in step a is to carry out molding using one or more of machining, casting, forging, punching press, welding manner mode, and described assembling position is one or more of through hole, counterbore, straight hole, taper hole, straight trough or skewed slot.
E. heat treatment: extruding finished product is carried out heat treatment, obtains complex abrasion-proof product.By heat treatment, improve the performance of metallic matrix further, thus the overall performance lifting complex abrasion-proof product.
Hard material (espespecially ceramic material) key property is partially crisp, plastic-less deformation's ability, thermal coefficient of expansion (and expandable characteristic after being heated) is relatively low with shrinkage factor (shrinkage during cooling) simultaneously, so cannot rapid expanding or contraction simultaneously inside and outside hard material when by chilling or anxious heat, the easily cracking broken phenomenon when internal stress increases to marginal value, lose its serviceability, the abrasion-resistant metal product that this characteristic largely limits a lot of hard materials (espespecially ceramic material) carries out heat treatment, eventually affect the whole service life of wear resistant products.
And this technique can be by ceramic tight metallic matrix by way of pressure or forging; in heating, ceramic material can be not directly contacted with thermal source; avoid anxious thermo-contact; but progressively can heat up with during metallic matrix heat conduction; metallic matrix defines effectively anxious hot thermal insulation layer; it is achieved thereby that the mode being slowly heated, same quenching process is similarly subjected to protect and enters the process of a Slow cooling, and is slowly heated and can avoid the cracking of ceramic material with Slow cooling and crush；And, because metal matrix material is that tight has lived ceramic material under stress, microfissure and also can be wrapped gift constraint in technical ceramicses material, crackle will not be made to continue to be extended to macroscopic cracking, have no effect on macroscopical anti-wear performance of pottery.
So, this technique achieves metal matrix material ceramic material undamaged effect in heat treatment process, the wearability of metal matrix material can be increased substantially simultaneously, during actually used, metal matrix material and ceramic material all play higher wearability, so that the whole service life of wear resistant products is increased substantially.
By way of pressure processing, metal matrix material is combined with each other with hard material, metallic matrix consistency after pressure processing improves, grain size is effectively refined, and hard material can effectively be wrapped in matrix material, play the abrasionproof effect of key, can possess the performance of heat treatment, the overall service life improving wear resistant products simultaneously.
After metal is combined with nonmetallic materials, not only obtain retaining metal plasticity and toughness and the composite better than metal wear resistant material and product, simultaneously because the density of nonmetallic materials is far below metal material, so making integral product achieve light-weight design, when equipment runs can greatly reducing energy consumption, be to save energy consumption cost using enterprise.
This technique can be using in conventional fabrication processes, after certain production link carries out effective transformation of equipment, realize manufacturing the higher product of added value using current production line, for example: the technique adding pressure processing in the production link of traditional rolled plate, it is that hard material is directly entered in the sheet material of rolling, realize the batch production of wear-resisting steel plate, thus realizing for direct for general steel plate deep processing becoming wear-resisting steel plate, and the market value of wear-resisting steel plate is 5-10 times of general steel plate market value.
The consumption of high-abrasive material resource largely saved by the composite of this technique manufacture, simultaneously can be using the waste material of other industries or leftover pieces, but still keep the waste recovery of preferable wearability, be combined with this technique, realize resource reutilization energy-conserving and environment-protective circulation manufacturing industry chain.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any modification, equivalent and improvement made within the spirit and principles in the present invention etc., should be included within the scope of the present invention.
