Description
Technical field
The present invention relates to a kind of bearing mnanufacture equipment, especially a kind of ceramic bearing manufacturing equipment.
Background technology
Ceramic bearing has high temperature resistant, cold-resistant, wear-resisting, corrosion-resistant, diamagnetic electricity absolutely as a kind of important mechanical basic part
The characteristics such as edge, oil-free self lubrication, high rotating speed, environment and special operation condition available for extreme.Because it has metal bearing
Incomparable premium properties, be widely used in Aeronautics and Astronautics, navigation, oil, chemical industry, automobile, electronic equipment, metallurgical, electricity
The fields such as power, weaving, pump class, medicine equipment, scientific research and national defense and military.For special car, most of they are operated in operating mode
, it is necessary to often repair and change spare and accessory parts in rugged environment, the Fast Wearing of metal bearing and deformation are also one big
Problem.And ceramic bearing is suitable for the operation under the mal-condition for being covered with Korrosionsmedium with corrosion is not afraid of；Expanded with heat and contract with cold
Influence I allow bearing worked in the more violent environment of difference variation；The density ratio steel of rolling bead is low, and weight is more
It is light, therefore 40% can be reduced to the centrifugal action of outer ring during rotation；Modular ratio steel is high, has been unlikely to deform during stress
The advantages that beneficial to improving operating rate, and reaching degree of precision etc., it is that instead of the splendid selection of metal bearing in special car.But
It is to compare metal bearing, the impact resistance of ceramic bearing is poor, travels easily cause on the bad road of road conditions for a long time
The breakage of bead inside ceramic bearing, serious meeting causes the cracking of bead to scrap whole ceramic bearing, if ceramic bearing
It must just strengthen its impact resistance when being applied to instead of metal bearing on special car.
The manufacture method of ceramic bead mainly uses hot isostatic pressing method in present ceramic bearing, is both put into ceramic powders
In sheath material, pressurization then is heated to it and is made.
The content of the invention
The present invention is directed to deficiency of the prior art, there is provided a kind of automobile bearing manufacture device, can by the present apparatus
Produce the ceramic balls with internal frame so that the impact resistance of ceramic balls greatly strengthens, and solves ceramics rolling in the past
The problem of pearl is made up of pure ceramic powders, and shock resistance is weak.
In order to solve the above-mentioned technical problem, the present invention is addressed by following technical proposals：A kind of automobile bearing manufacture
Device, including heat isostatic apparatus, described heat isostatic apparatus includes plus-pressure furnace, pressue device and heater, described
Several reusable graphite jackets are additionally provided with plus-pressure furnace, described graphite jacket includes lower jacket lid and upper jacket

The waste material box of dismounting, the reject chute being connected with the lower half spherical cavity, described upper half spherical cavity are provided with described waste material box
Top is provided with sprue.
In above-mentioned technical proposal, it is preferred that described waste material slot cross-section is in inverted trapezoidal.
In above-mentioned technical proposal, it is preferred that described upper jacket covers the ring screw face that is provided with, described lower jacket lid
On be provided with the ring screw groove being engaged with the ring screw face.
In above-mentioned technical proposal, it is preferred that in a ring, described waste material box passes through helicitic texture and institute to described waste material box
The lower jacket lid stated is tightly connected.
In above-mentioned technical proposal, it is preferred that some evenly distributed graphite fix bars are provided with described pressurizing chamber,
Described graphite jacket can be fixed in described graphite fix bar, and it is removable that described graphite, which is wrapped in described fix bar,
Unload.
In above-mentioned technical proposal, it is preferred that described lower jacket, which covers, is provided with two symmetrical fixed ears, and described consolidates
Determine to be provided with the fixing hole being engaged with the graphite fix bar on ear.
In above-mentioned technical proposal, it is preferred that dismountable closure, described sealing are additionally provided with described sprue
Lid is connected through a screw thread with described sprue.
In above-mentioned technical proposal, it is preferred that described lower jacket lid and described upper jacket cover and be both provided with clamping face.
This automobile bearing manufacturing equipment has resistance to height mainly for the production of automobile using ceramic balls, known ceramic bearing
Warm, cold-resistant, wear-resisting, corrosion-resistant, diamagnetic electric insulation, oil-free self lubrication, high rotating speed etc. good performance, but ceramic bearing
Impact resistance is poor compared with metal bearing, is sayed for automobile, it is often necessary to is travelled in different landform, to the anti-impact of bearing
Hitting property requires very high, and existing ceramic bearing can not meet the requirement of running car substantially.For this, the application improves ceramics
The production method of ball so that ceramic bearing has the impact resistance no less than metal bearing, and ceramic bearing can be allowed to be applied to car
.
The application improves the structure and material of Ceramic Balls embryo jacket in heat isostatic apparatus, and known Ceramic Balls embryo needs
To be molded by heat isostatic apparatus, in order to allow Ceramic Balls embryo to reach good anti-impact force, it is necessary to have in ceramic balls interior
The graphite skeleton put, the lower jacket lid that can be separated and upper jacket lid are devised for this, first prints graphite in lower jacket lid
Skeleton, the material feeding of ceramic powders is being carried out to graphite jacket after then closing up lower jacket lid and upper jacket lid.Due to graphite skeleton
Outside can not being exposed to, also need to first print resin-base before graphite skeleton is printed, but tree can not be included in ceramic balls
Fat composition, it is that this also sets reject chute in lower jacket base portion, in hot isostatic pressing, low-melting resin melts first,
The resin of thawing is flowed into reject chute, while ceramic powders tie up the space of resin-base in spherical cavity, and part ceramic powder can also
Drop onto in reject chute, as long as high temperature insostatic pressing (HIP) just both can guarantee that Ceramic Balls embryo was not set after material in reject chute is sliced off after terminating
Fat composition also can guarantee that graphite skeleton forming in Ceramic Balls embryo center.
The ceramic balls that device is produced in the application have built-in graphite skeleton, can be good by graphite skeleton
Conduction and the impulsive force that is subject to of dispersed ceramic ball so that influence of the impulsive force to ceramic balls ceramic body diminishes, popular
Say and the overall elasticity of ceramic balls is added by graphite skeleton so that the anti-impact force of ceramic balls is greatly lifted, and allows pottery
Porcelain ball in the environment of jolting also can normal use do not ftracture, be not damaged, suitable for automobile use environment.
Compared with prior art, the beneficial effects of the invention are as follows：It can be produced with internal frame by the present apparatus
Ceramic balls so that the impact resistance of ceramic balls greatly strengthens, and solves conventional ceramic balls by pure ceramic powders system
Into the problem of shock resistance is weak.
