Order, 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 by this
The embodiment person of ordinary skill in the field of utility model is understood.
As shown in figure 1, the utility model provides a kind of tube extrusion former, including for being connected to spiral squeezing
Current divider 5 is provided with handpiece body 4 and porous plate 3 on the extruder head 1 of machine, the handpiece body 4, as described in Figure 2, the shunting
It is disposed with device 5 on plug 7, support 8 and spreader 9, the handpiece body 4 and is provided with mouth mold 6, the plug 7 stretches into mouth
In mould 6, the cone of the spreader 9 is set towards the porous plate 3, axially disposed fluted on the outer wall of the plug 7
10；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 passes through the rectification of porous plate 3, is flowed into head, spreader 9 is divided 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 with the groove 10, the structural strength of tubing has very big compared to conventional tubing
Lifting, especially greatly improves 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；It is described 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.
The extruder head 1 that porous plate 3 is installed in extruser is exported, 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 grade of current divider 5 position, porous plate 3 can carry out rectification to plastic liquid.Fluidised form
Plastic liquid is flowed into cushion chamber 11 by charging hole 12, passes through first step rectification, plastics by plastic liquid during charging hole 12
Fluid streamline has tended to the state of laminar flow, and the flow velocity on each streamline reaches unanimity, and is buffered by cushion chamber 11, will be thorough
The spiral of plastic liquid flows to and improves state turbulent in plastic liquid after elimination spiral squeezing.
After cushion chamber 11 is buffered, plastic liquid flow on the left of discharge opening 13 and flowed out by left side discharge opening 13, enter
And can enter in current divider 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, plastic liquid each is put in subsequent handling density and thickness can
Keep always, the consistent finished product tubing of wall thickness being obtained.
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 viscosity inside plastic liquid to become big because temperature drop, flow velocity slow down etc., through-current capability declines
Situation.
Region at the nearly center of porous plate 3, the sparse arrangement of charging hole 12 and 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 close to 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, close arrangement；So doing can
To adjust through-flow ability so that the through-current capability by the central area of porous plate 3 dies down, hence it is evident that lower passing through for unit interval
Amount, the through-current capability away from the central area of porous plate 3 becomes strong, hence it is evident that increase the throughput of unit interval, intentionally will be along plastics stream
The flow velocity adjustment of each position in body cross-sectional direction is close.
