Description
Technical field
The present invention relates to processing molds, more particularly to a kind of mold and processing unit (plant) of processing pipe internal thread.
Background technology
Planet ball mould spinning process by steel ball and the cooperation of spinning ring is the main stream approach of current forming of internal thread copper pipes.State
Interior application planet ball mould spinning process production inner screw thread copper pipe nearly more than 20 years, bearing steel ball and spinning ring are always planet ball mould
The fixed Combination of spinning process production, with shaping speed height, molding energy consumption is small, and die cost is low, easy to install and dismounting, technique
Many advantages, such as simple is adjusted, therefore obtains universal approval.But during producing inner screw thread copper pipe using bearing steel ball
Simultaneously it has also been found that its apparent disadvantage：The steel ball service life is low, and copper pipe surface unstable quality, surface flower steel ball even often occur and break
Damage leads to the generation of copper pipe surface evident regularity spot defect, influences product lumber recovery, this phenomenon can cause the generation secretly split from
And the service life of client's copper pipe can be influenced.
The main assembly method of production inner screw thread copper pipe at present, steel ball and spinning ring is auxiliarily fixed mode for nothing and assembles, i.e.,
Steel ball coordinates by spinning ring and motor revolving sleeve.Such as Fig. 1, the structure of existing mold, upper spinning ring 11 and backspin pressure ring 12
Relative engagement, then sphere 13 be placed between two spinning rings, this fit system, upper spinning ring 11 and backspin pressure ring 12 it
Between can relatively move and rotate, sphere 13 can also and rotation mobile relative to two spinning rings.This fit system is no auxiliary
Fixed form is assembled, and mold is assembled and then by its entire assembly in motor revolving sleeve, is turned together with motor revolving sleeve
It is dynamic.In addition also there is part of the manufacturer to separate steel ball using retainer, steel ball is avoided to be in direct contact with spinning ring, but not because of effect
It is good and do not obtain high-volume promote.Being assembled without the mode that is auxiliarily fixed has many advantages, such as that installation is simple, easy to adjust, but its disadvantage
Have：Gap between spinning ring and steel ball is uncontrollable, and the cooperation of pairs of spinning ring and revolving sleeve is uncontrollable, uncontrollable in the above
In the case of, in high-speed rotation process, dynamic balancing cannot be completely secured motor, while be easy to cause spinning ring because assembly is bad
Track and steel ball Impact direction change, and accelerate the abrasion of steel ball and spinning loop orbit, and it is of poor quality to eventually lead to copper pipe surface,
Surface regularity is whitened, and surface wave and naked eyes are invisible but the case where signal is obviously got higher after eddy current inspection.
As air conditioner industry further seeks for brilliance, Copper fabrication industry also follows continuous development, to quality, cost and effect
Rate requires to be increasingly stringenter.Steel ball because itself material and processing technology limitation, there are the service life is low in copper pipe production application,
The disadvantage of quality stability difference, therefore, the sphere material for seeking higher precision, high-wearing feature and high performance-price ratio are certainty

Part is widely used in the support shaft of the rotating members such as high-speed electric main shaft, aero-engine, precision machinery motor and high speed surbine
It holds.The combination of steel ball and spinning ring is actually from bearing type differentiation, and therefore, it is always that copper adds to substitute steel ball using Ceramic Balls
The potential trend of industrial and commercial bank's industry.
The common used material for making Ceramic Balls is silicon nitride (Si3N4), silicon carbide (SiC), aluminium oxide (Al2O3) and zirconium oxide
(ZrO2).In these four ceramic material bearing balls, the comprehensive performance of Si3N4 is best.Si3N4 has high temperature resistant, corrosion-resistant, electric
The performances such as insulation, nonmagnetic, high intensity, density is small.Silicon nitride ceramic ball is the accurate pottery being sintered in nonoxidizing atmosphere high temperature
Porcelain, have high intensity, high-wearing feature, high temperature resistant, it is corrosion-resistant, acidproof, alkaline-resisting, can be used for a long time in the seawater, and have insulation
The superperformance of exhausted magnetic.At 800 DEG C, intensity, hardness are almost unchanged, and centrifugal force is small when rotation, may be implemented to run at high speed.Also
With self lubricity, it can be used in the environment of unlubricated medium high pollution, be ceramic bearing, hybrid ceramic ball bearing
Preferred ball.
But existing mold cannot use silicon nitride ball as sphere, due to the architectural characteristic of existing mold, easily
So that silicon nitride ball is damaged in the rotation, under such structure, the service life of silicon nitride ball is not grown, and cannot preferably be replaced
For steel ball.
