The utility model is further arranged: the spacing between the adjacent through-hole is 3-5 millimeters.
By adopting the above technical scheme, the spacing between adjacent through-holes is limited, the diameter of through-hole can be made more reasonable, with
It is actual to need more to match, further increase uniformity of the clad by adsorption capacity.
The utility model is further arranged: the ring block close to extruder is equipped with external screw thread, and the discharging with extruder
It is threadedly coupled at mouthful.
By adopting the above technical scheme, it will be threadedly coupled at calibration tube and extruder discharging mouth, it can very firm calibration tube
It is fixed on extruder, can be convenient the installation and removal of calibration tube, convenient for replacement of the calibration tube in damage.
The utility model is further arranged: being equipped with arcwall face at the ring block inner wall edge.
By adopting the above technical scheme, the arcwall face of setting can be in contact with cover surface, it is possible to reduce with clad
Between frictional force so that clad during transportation can be more smoothly.
The utility model is further arranged: the diameter of the ring block is greater than the outer diameter of sizing tube body.
By adopting the above technical scheme, the outer diameter of limitation sizing tube body, the ring block being relatively large in diameter can increase entire sizing
The intensity of pipe, meanwhile, when manpower holds calibration tube, ring block can play the role of limitation to manpower, it is possible to reduce take
When putting calibration tube, the case where calibration tube slides from hand.
In conclusion the utility model has the following beneficial effects:
Calibration tube is installed by the discharge outlet in extruder, through-hole is opened up on calibration tube, when clad is from calibration tube
It is interior by when, can use vacuum device to calibration tube carry out pumping process so that clad is bonded with the inner wall of calibration tube
Together, so that cladding layer cross section after molding is rounded, the product quality and property of clad then can be improved
Energy；
By the way that through-hole uniform crossover to be distributed on calibration tube, then the adsorption capacity that clad can be made to be subject to is more equal
It is even, be conducive to clad and be closely bonded with sizing inside pipe wall, so as to further increase the circle of molding sizing tube section
Whole degree.
