Description
Technical field
The utility model relates to field of plastics processing, and in particular to a kind of online double-wall bellow flare device.
Background technique
Hard PVC double-wall corrugated pipe abbreviation PVC-U double-wall corrugated pipe is the new production of German late nineteen seventies exploitation
Product, acquirement patent in 1979.This tubing can replace traditional metal tube, pipe of cement, ceramic tube and plastic tube etc., for leading to
News, municipal administration, irrigation and water conservancy etc..Double-wall PVC bellows, which removes, has the corrosion-resistant of common plastics tube, good insulating, inner wall light
Also have following unique technical performance other than the features such as cunning, long service life: 1, structure Special Ring is rigidly strong, 2, unit self weight
It is gently, 3, flexible that connect leakproofness strong.
Being laid with Double-wall PVC bellows, method is simple.Single tube is continuously extremely easy, only need to be by socket end third wave
Line puts on rubber ring, and insertion female end applies external force in the other end of continuous pipe, joint rubber ring is entered in bellmouth.
The flared part of offline processing PVC-U double-wall corrugated pipe remains main processing method at this stage, using flaring machinery to even
After continuous tubing carries out reheating, inside swell after processing using expansion mechanism, then the mode of cooling and shaping produces
Double-wall corrugated pipe with flaring.
The production method of present PVC-U double-wall bellow flare existing on the market has difference completely, domestic at present raw
The PVC-U double-wall bellow flare part of production is that completion is manufactured by two-step method.Continuous tubing is first produced into six meter one
The straight tube of root, one end of straight tube, which is then carried out heating, again makes its softening, then the flaring die of flaring machinery is recycled to be inserted into
The inside of tubing, flaring die will expand together after swelling inside and outside tubing to become larger, finally in utilization air to its cooling and shaping.It is this
Method the shortcomings that: 1, the temperature and time length of tubing secondary heating need stringent control, 2 heating have to keep tubing whole
A circumference internal/external heating uniformly, 3, phenomenon that tearing or breakage are had in tubing expansion process, 4, outer wall meeting after tubing expansion
There is the place collapsed.
Utility model content
The purpose of the utility model is to overcome above-mentioned the problems of the prior art, provide a kind of online double-wall corrugated pipe
Expanding device.
What the purpose of this utility model was achieved by the following technical programs:
A kind of online double-wall bellow flare device, including injection molding module, flare formation module and vacuum cooled system
System, the flare formation module are connected with injection molding module, and the vacuum cooling system is arranged in the flare formation mould
On block, the flare formation module includes pipe outer wall stream cavity, inner air vent cavity, inside pipe wall stream cavity, outer gas hole cavity
And vacuum suction device, outer gas hole cavity are arranged between pipe outer wall stream material cavity and inside pipe wall stream cavity, it is described interior
The inside of inside pipe wall stream cavity is arranged in stomata cavity, and the vacuum suction device is connected with pipe outer wall stream cavity.
Flare formation module is assumed in one end of the injection molding module of processing double-wall corrugated pipe, so as to realize injection molding
One production line of molding and flaring is completed at the same time, and there is no need in addition carry out reheating to tube body again to be flared again.Expanding
It is additionally provided with vacuum cooling system on mouth device, the cooling for being more advantageous to tube body after being flared is conducive to the molding of tube body flaring.
Vacuum suction device is hollow being pumped into outer wall stream cavity, is adsorbed on ripple pipe outer wall under the action of vacuum
In flare formation module, while bellows external wall material can also be held up and blow to flare formation mould by the gas in the cavity of outer gas hole
Block.Then the vent valve of outer gas hole cavity is opened, and increases the air pressure of inner air vent cavity, inner wall drains while sticking outer wall
Gas in the cavity of outer gas hole, so that inside and outside wall, which is adhesively-bonded together to form, thickeies single layer flaring.
Preferably, the vacuum suction device includes multiple vacuum suction slots.
Preferably, the flare formation module is connected with injection molding module by extrusion die.
The utility model has following technical effect that compared with prior art
A kind of online double-wall bellow flare device, including injection molding module, flare formation module and vacuum cooled system
System, the flare formation module are connected with injection molding module, and the vacuum cooling system is arranged in the flare formation mould
On block, in production, the picking-up of bellows external wall material is blowed to by flare formation module by inside and outside wall interbedded gas, later by outer gas
It runs through exhaust valve gas is discharged, is then adsorbed on the outer wall of bellows using the vacuum plant in flare formation module
In flare formation module, at the same internal layer gas by the inner wall of bellows blow afloat patch on the outer wall, enable two layers of inside and outside wall it is close
Be adhesively-bonded together to form one it is complete whole, ripple inside pipe wall and outer wall form seal cavity, and interbed gas vent valve is beaten
It opens, and increases internal layer gas, inner wall venting interbed gas while sticking outer wall.Online molding flared part is thus reached
Effect, so that the time is greatly saved in the production of tubing.
