Also referring to Fig. 1 to Fig. 4, now steel-plastic composite pressure pipe skirt attachment device provided by the utility model is carried out
Explanation.Steel-plastic composite pressure pipe skirt attachment device is parallel to the setting of skirt 400 for two sections of skirts 400 of connection, including main shaft
Heat-resisting axis 100, the rotation that is sheathed on the periphery at heat-resisting 100 both ends of axis and is slidably connected in a circumferential direction with heat-resisting axis 100
It disk 200, the overhanging push rod component 300 for holding out against 400 inner wall of skirt and is set between rotating disc 200 and heat-resisting axis 100
And the locked component 500 for locking rotating disc 200 Yu heat-resisting axis 100, one end of overhanging push rod component 300 and heat-resisting axis 100
Hingedly, along the connection that radially slides of rotating disc 200, rotating disc 200 is heat-resistant component for the other end and rotating disc 200.
As shown in fig. 1, in the molding of internal plastic tube 600 and gluing process, needing dragger 640 to draw skirt 400 will
Internal plastic tube 600 is pulled out from extruding machine 610, is carried out sizing sequentially through cooling sizing tank 620, is then passed through hot interior sealing rubber die
630 carry out the coating of the glue-line on the outer wall of internal plastic tube 600, due to needing to 600 He of internal plastic tube when extruding machine 610 is switched on
Skirt 400 is attached operation, so the high temperature at hot interior sealing rubber die 630 will cause the hot melt damage of skirt 400, so
Rotating disc 200 made of the heat-resisting axis 100 of the present apparatus and external heat proof material can effectively connect the skirt 400 of two sides, together
When be also avoided that hot interior sealing rubber die 630 at booting initial stage, damages the hot melt of two skirts, 400 intermediate connections.Use process
In, the rotating disc 200 of heat-resisting 100 one end of axis is rotated around heat-resisting axis 100 to overhanging push rod component 300 and 400 inner wall of skirt and is supported
After connecing, the relative position of rotating disc 200 and heat-resisting axis 100 is locked by locked component 500, is then operated using same,
It will be formed between the rotating disc 200 of the other end of heat-resisting axis 100 and the inner wall of another skirt 400 and abut and lock heat-resisting axis
100 other end and rotating disc 200 realizes effectively connecting to the skirt 400 of hot interior 630 two sides of sealing rubber die by the present apparatus
It connects, while the present apparatus can also bear the high temperature at hot interior sealing rubber die 630, avoids in the hot interior sealing rubber die of equipment initial start stage
Damage is heated caused by the skirt 400 of 630 pairs of integral forms.The heat-resisting axis 100 used in the present embodiment is the structure of nylon material
Part also has good intensity and toughness while guaranteeing good heat resistance, can generate with 400 inner wall of skirt good
Withstanding effect, while equipment investment cost can also be effectively reduced, in addition rotating disc 200 also uses nylon material component, is convenient for
Subsequent structural processing is carried out, there is good practicability.
Steel-plastic composite pressure pipe skirt attachment device provided by the utility model, compared with prior art, the utility model
The rotating disc 200 at heat-resisting 100 both ends of axis is respectively placed in skirt 400 by the steel-plastic composite pressure pipe skirt attachment device of offer
It is interior, by rotating rotating disc 200 relative to heat-resisting axis 100, realize that overhanging push rod component 300 is held out against to 400 inner wall of skirt
Effect, and then hold out against entire attachment device with 400 inner wall of two sides skirt, guarantee to be connected firmly between two sides skirt 400, keep away
Exempt to fall off, since the setting of heat-resisting axis 100 can effectively avoid hot interior glue in internal plastic tube 600 and 400 connection procedure of skirt
Mold 630 guarantees the stable traction molding of internal plastic tube 600 so having good using effect to the thermal damage of skirt 400,
Tradition is avoided by the damage of dragger crawler belt caused by hook connection two sides skirt, while under the at the uniform velocity traction of dragger
The quality stability that 600 product of internal plastic tube can also effectively be enhanced guarantees going on smoothly for production.
