Description
Technical field
The present invention relates to the technical fields of the process units of PPR water-feeding pipes, and it is cooling to be more particularly to a kind of novel PPR pipe
Shaping equipment.
Background technique
Currently, the common sizing mode of PPR pipe is outer diameter sizing method.Outer diameter sizing method is to make outer pipe wall and shaping cover
The method that inner wall contacts and obtains tube outer diameter sizing is mainly vacuum method.
Vacuum shaping mode is a kind of plastic tube sizing mode most widely used, also most being praised highly at present.By traditional
Idea, usually only the PPR drainage pipe less than 3 inches, the mode that just will use Vacuum shaping manufacture.Because of this plastic tube
Wall than relatively thin, Vacuum shaping device is structurally and operationally all fairly simple in addition, easy to operate and control；Not necessarily like operating and make
It is such with compressed air shaping device, worry that the chain for holding vent plug breaks suddenly.Vacuum shaping device is usually fixedly placed in cooling
The front end of case, 2 inches of PPR pipes below generally use dipping bath formula cooling.Water in cabinet is both cooling medium and plastic tube
The lubricating action for reducing friction is played between calibrator.Therefore, using Vacuum shaping, the PPR pipe of cooling, outer surface is very
It is bright and clean.Simultaneously as friction is small, pulling equipment is also corresponding smaller.Another additional feature of Vacuum shaping mode
It is that, since tubing generates concussion in cutting, PPR pipe dipping bath in water, can play the role of damping, avoids therefore influencing just
Ripple is generated in the PPR heat pipe embryo surface squeezed out.Especially when the cutting that planet cutter is carried out around heavy caliber, thick-walled pipe
The moment soon completed is acted, the vibration of generation is maximum.Because the structure for cooling water tank of being formed is can to carry out forward and backward movement,
And adjust above and below, although the design of such mechanism facilitates operation, the stability of its framework seems very not good.PPR
The Vacuum shaping of pipe is under the hot plastic state of 190 ~ 210C, by the vacuum suction window and dragger of calibrator outer surface
Longitudinal stretching under quickly complete, while the physical property of tubing also basically forms.The control pressure one in Vacuum shaping stage
As be in -0.03 ~ -0.05MPa range, mainly depending on plastics variety, pipe diameter size and tube wall thickness.We often pass through control
The size of vacuum pressure value processed, to reach the percent thermal shrinkage and impact strength of control PPR pipe.In fact, working as the inner hole of calibrator
When becoming larger because of abrasion, the outer diameter of pipe can also be made to reach standard regulation by being slightly reduced vacuum pressure, to increase percent thermal shrinkage
Requirement.But, vacuum pressure is typically no less than -2500Pa.The water temperature of sizing cooling water tank should be maintained at 25 ~ 28 as far as possible
°C, effectively the percent thermal shrinkage of UPVC drainpipe could be controlled in 3 % ~ 5%.After water temperature is more than 28 °C, the heat of PPR pipe
Shrinking percentage will become larger.Furthermore, it is contemplated that " buoyancy " of water acts on, the UPVC pipe greater than 2 inches is preferably cooling with fountain, especially
It is to heavy walled pressure pipe.

It is as shown in Figures 1 to 3 a kind of embodiment of novel PPR pipe cooling and shaping device of the present invention, PPR pipe cooling and shaping
Device includes water dish 2 and cooling and shaping set 4, and water dish 2 is set to the end that cooling and shaping covers 4 one end, the cooling and shaping dress
The regulating device 5 for being additionally provided with and covering the outlet diameter of 4 the other end for adjusting cooling and shaping is set, cooling and shaping set 4 is high-tensile strength copper
Material production.Main material of the present embodiment power copper as cooling and shaping device, the wearability of the shaping cover of raising increase
Thermal coefficient makes tubing in a short period of time can be with cooling and shaping.
Wherein, water dish 2 covers the end of 4 one end around cooling and shaping.Setting is in order to by cooling water peripheral jet in this way
In appearance to pipe.
In addition, cooling and shaping set 4 is equipped with several cooling water apertures 3 convenient for accelerating the cooling of PPR pipe base 1.It is arranged in this way
It is the cooling effect in order to increase shaping cover.
Wherein, regulating device 5 is tail portion rotating nuts.In this way setting be in order to bigger than normal or less than normal in the tube outer diameter arrived,
It can rotate clockwise or rotate counterclockwise to adjust the diameter of shaping cover outlet, thus directly at the tail portion rotating nuts of shaping cover
Connect the size for influencing the outer diameter of tubing.
In addition, the adjustable range that tail portion rotating nuts adjust cooling and shaping set 4 is -1mm ~ 1mm.It should be noted that this
It is a only preferred, it is not restrictive regulation.
Wherein, cooling and shaping set 4 is equipped with the vacuum window 41 for adsorbing 1 surface of PPR pipe base.In this way setting be in order to
The outer surface of pipe is attached on the interior internal surface of hole of shaping cover by vacuum window under the action of vacuum.It is this novel
