Description
Technical field
It is processed the present invention relates to steel pipe processing technique field more particularly to composite steel tube organisation of working, using the mechanism
Structure enhanced type drainpipe.
Background technique
The drainpipe of the prior art mostly uses two kinds of forms of steel pipe or plastic tube.Wherein, steel pipe has good intensity,
But its anticorrosive property needs to be improved；Though plastic tube such as PP pipe, pvc pipe or PE pipe have with good anticorrosive property, strong
Degree is insufficient, and the tube breaking phenomenons such as cracking often occur.
In order to improve the intensity of plastic tube, currently, mostly using the mode squeezed out after plurality of raw materials mixing in the market to improve
Enhancing auxiliary material is added that is, in conventional resins master batch to improve the intensity of tube body entirety in intensity.Such as patent application
201410199700.8 disclosed Fiberglass-reinforcepolypropylene polypropylene plastic and preparation method thereof, patent application 201410199325.7
Disclosed activeness and quietness polypropylene plastics.However, since the substrate that above-mentioned tubular body uses remains as resin, intensity amplification range
It is limited, it is unable to get and is significantly promoted.
Compound reinforcement tubulation is the multilayer pipe structure for forming steel pipe in conjunction with plastic tube, attached in traditional steel tube surface
One layer of resin layer, the integral strength of tube body is on the one hand improved using steel pipe layer, on the other hand utilize resin layer corrosion resistant
Corrosion improves tube body corrosion resistance.The mode for adhering to resin layer includes spraying and coating etc..Wherein spraying and loading is difficult to protect
It demonstrate,proves the homogeneity of feeding and interface cohesion between the bed of material and inner wall of the pipe is not sufficiently effective, the bed of material is easy to fall off；In addition, feeding
Thickness is not easy to control, leads to the deficiency of tube body inner thickness homogeneity difference.Coat feeding such as patent application 201420411896.8
A kind of disclosed anti-corrosive steel tube realizes the feeding in outside in tube body using the technique that multilayer continuously coats.Multilayer continuously coats work
Although skill makes moderate progress on expecting the binding strength with pipe compared to spraying process, there are the deficiencies more than complex process, process.
Tubing needs to carry out cooling and solidifying processing after extrusion molding.The type of cooling of the prior art include air it is cooling with
And two kinds of water cooling.Air is cooling to have good stationarity, and after cooling, the stress concentration phenomenon of tube body is unobvious, but exists
The long deficiency of cooling route.Although water cooling is able to achieve rapid cooling, but abrupt temperature drop, may influence the intensity of tubing.
It is well known that the industrialized realization of tubular object extruding flowing water is based on multiple working procedures such as feeding, molding, cutting, coolings
Work continuously.And the cooperation between each workshop section of the prior art is mostly manual operation, and is mutual between different production lines
It is independent, cause equipment investment big, place occupied area is also to be improved.

And two kinds of water cooling.Air is cooling to have good stationarity, and after cooling, the stress concentration phenomenon of tube body is unobvious, but exists
The long deficiency of cooling route.Although water cooling is able to achieve rapid cooling, but abrupt temperature drop, may influence the intensity of tubing.This hair
It is bright that tube body is precooled in advance by conveyer belt 66, enters back into water and cools down, cooling efficiency can be improved but also had
The phenomenon that effect prevents tube body stress from concentrating.Tube body of the invention can be passed through into guiding cantilever 63, this hair after the extrusion of die head 4
When bright guiding cantilever 63 is in a horizontal state, it can assign tube body certain support positioning action, be cut convenient for cutting machine 65；
When guiding cantilever 63 is in heeling condition, it can be slid into sink 61 for tube body and play guiding role, guarantee that tube body is gentle, accurate
Blanking.
