Sequence, including according to involved function by it is basic simultaneously in the way of or in the opposite order, carry out perform function, this should be of the invention
Embodiment person of ordinary skill in the field understood.
As shown in figure 1, the invention provides a kind of tube extrusion former, including for being connected to extruser
Diverter 5 is provided with handpiece body 4 and porous plate 3 on extruder head 1, the handpiece body 4, as described in Figure 2, the diverter 5
On be disposed with plug 7, support 8 and spreader 9, mouth mold 6 is provided with the handpiece body 4, the plug 7 stretches into mouth mold 6
In, the cone of the spreader 9 is arranged towards the porous plate 3, axially disposed fluted 10 on the outer wall of the plug 7；
One end of the groove 10 connects the outer face of the plug 7, and the other end connects the side of the support 8.
The plastic liquid of fluidised form is flowed in head through the rectification of porous plate 3, and spreader 9 is carried out point to plastic liquid
Stream, plug 7 and mouth mold 6 carry out the shaping of tubing.Groove 10, the inwall of the tubing after shaping are set on the outer wall of plug 7
The upper shape identical reinforcement having with the groove 10, the structural strength of tubing has very big compared to conventional tubing
Lifted, especially greatly improve anti-twisting property, while also overcoming the risk of the uneven caused intensity decreases of pipe thickness.
As shown in Figure 3 and Figure 4, the porous plate 3 has the left side and right side being parallel to each other, the porous plate 3
Left side and the gluing, sealing of the handpiece body 4, the right side of the porous plate 3 and the gluing, sealing of the extruder head 1；The porous
Cushion chamber 11 is provided with plate 3, the right side of the porous plate 3 is provided with several charging holes 12, the charging hole 12 and buffering
Chamber 11 is connected；The left side of the porous plate 3 is provided with several discharge openings 13, and the discharge opening 13 is connected with cushion chamber 11；
The axial location of the axial location of several discharge openings 13 and several charging holes 12 mutually staggers.
Porous plate 3 is installed in the extruder head 1 of extruser and exports, and the plastic liquid of fluidised form is after the extrusion of screw rod 15
By porous plate 3, then it is flowed into again on the positions such as diverter 5, porous plate 3 can carry out rectification to plastic liquid.Fluidised form
Plastic liquid is flowed in cushion chamber 11 by charging hole 12, and plastic liquid is through first step rectification, plastics when charging hole 12
Fluid streamline has tended to the state of laminar flow, and the flow velocity on each streamline reaches unanimity, and buffers through cushion chamber 11, will be thorough
The spiral for eliminating plastic liquid after spiral squeezing flows to and improves the state of turbulent flow in plastic liquid.
When cushion chamber 11 buffer after, plastic liquid flow on the left of discharge opening 13 and flowed out by left side discharge opening 13, enter
And can enter in diverter 5.Entered the further rectification of discharge opening 13, plastic liquid flow velocity slows down, and laminar flow increases, each
The flow velocity of position is basically identical.By such rectification, the density and thickness of each point can in subsequent handling for plastic liquid
Keep always, it is possible to obtain the consistent finished product tubing of wall thickness.
Heater strip 14 is provided with the porous plate 3, heater strip 14 can be heated to porous plate 3, and modeling is effectively ensured
The temperature of stream body, prevents from causing plastic liquid inside viscosity to become big because temperature drop, flow velocity slow down etc., and through-current capability declines
Situation.
In the region at the center of nearly porous plate 3, the charging hole 12 and the sparse arrangement of the discharge opening 13；Away from porous plate
The region at 3 centers, the charging hole 12 and the discharge opening 13 are closely arranged.In the region near the center of porous plate 3, plastics stream
The flow velocity of body is higher, therefore can reduce charging hole 12 and the quantity of discharge opening 13, sparse arrangement；Away from the center of porous plate 3
Region, the flow velocity of plastic liquid is relatively low, therefore can increase charging hole 12 and the quantity of discharge opening 13, closely arrangement；Do so can
To adjust through-flow ability so that die down by the through-current capability of the central area of porous plate 3, hence it is evident that lower passing through for unit interval
Amount, becomes strong, hence it is evident that increase the throughput of unit interval away from the through-current capability of the central area of porous plate 3, intentionally will be along plastics stream
The flow velocity adjustment of each position in body cross-sectional direction is close to.
