Description
Technical field
The present invention relates to steel-plastics composite pipe pipe end seal technical fields, refer to specifically a kind of certainly molten fill-type steel plastic compount
Pipe pipe end seal machine and its mouth-sealing method.
Background technology
After continuously shaped steel-plastics composite pipe is blocked by certain length, truncation surface the phenomenon that there are steel wire leakages, to ensure
The performance of steel-plastics composite pipe, it is necessary to truncation surface is sealed, it is so-called to steel-plastics composite pipe pipe end seal in the industry at once,
Steel wire to be enclosed in modeling layer.
Currently, the sealing for steel-plastics composite pipe pipe end, is mainly the following sealing mode：1, by injection molding machine to pipe
Material end carries out injection molding sealing；2, it is sealed by the way of butt welding；3, it squeezes and heats using the interior outer mold of sealing machine
Pipe inner and outer surfaces make the plastics of pipe inner and outer surfaces flow to tube end face and carry out heating sealing.
Gradually replaced by other manner since the big efficiency of injection molding sealing investment is low in the first sealing mode.And it uses
Butt welding mode is sealed, and since there are steel wires in steel-plastics composite pipe, the sealing effect of pipe end is also bad, and also right after sealing
The interior external welding crimping that pipe end seal position occurs carries out machining.And the interior outer mold of sealing machine is used to squeeze simultaneously heating tube
The sealing mode of material surfaces externally and internally makes the steel-plastics composite pipe seal due to the position wall thickness reduction that pipe end is extruded after sealing
Warp, the weft of mouth position cause sealing to fail it is easy to appear phenomenon is exposed, and since its tubing seals end wall thickness quilt
After being thinned, when the tubing is connect with standard tubing or pipe fitting, connection will appear larger gap, thus directly affect pipe
The connection of material and using effect.And when heating sealing, although being provided with the structure heated to pipe end on sealing machine, envelope
It after mouthful, when being cooled down to having sealed pipe end, then need to be cooled down by the cooling equipment in periphery, and sealing machine cannot be passed through
Realize heating cooling integration, that is to say, that existing sealing machine does not have both heating and cooling function.
