At present, the manufacture method with the outer ripple plastic winding structural wall tube of hollow reinforced rib has three kinds usually.
The first, first have the first extruder to extrude melting bar plastic sheet material, on the circular forming cylinder then making this sheet material be spirally wound on side by side regularly continuously many little roller bearings of active rotation are housed.Simultaneously, trapezoidal tubular strengthening ribs is extruded by an other extruder, with the overlapping the slot position of same spiral winding mode cross-pressure each threaded plastic sheet material neighboring edge on tube wall after water-cooled vacuum sizing, trapezoidal tubular strengthening ribs bottom surface is through suitably heating, simultaneously because plastic sheet is in semi-molten state, after the rolling of pinch roller, the bar plastic sheet material of tubular strengthening ribs and two-layer mutual overlap joint fuses together, and forms the outer ripple plastic winding structure wall pipe with hollow reinforced rib.But this technique exists following defect: (1) is wound around after cooling and shaping due to stiffening rib, determining its height can not be too large, so the tube wall moment of inertia after shaping is less; (2) the bonding very difficult control of stiffening rib and tube wall, as too low in threaded plastic sheet temperature, then bonding difference; As temperature is too high, it is shaping that bar plastic sheet material then can be difficult to control from forming cylinder tenesmus; (3) complete bonding after, slot is left all the time in the side of stiffening rib, causes stress to concentrate, ambient temperature alternately change time face of weld progressively can be ftractureed by slot, easily cause tube wall be separated with stiffening rib and collapse.
The second, what first extruded by the first extruder is that both sides, ground are respectively with the special-shaped rectangular tube of the suitable shape fin of a mutual welding, this special-shaped rectangular tube is after vacuum cooling sizing, be spirally wound on forming cylinder, constantly extruded the melten gel of melting again by the second extruder to the fin connection part of the adjacent correspondence of the special-shaped rectangular tube of spiral winding side by side, be welded together through pinch roller rolloff.There is following shortcoming in this technique: this welding position is at the most weak part of tubing, and face of weld is little, melten gel amount is few, thus reduces tubing integral bending.
The third, first extrude by the first extruder the plastic shaped band that continuous print both sides have the tubular lobes including hollow cavity, this plastic shaped band is spirally wound on the forming cylinder of rotation continuously side by side, space is formed between two tubular lobes making adjacent plastic shaped band close to each other, in space, the plastisol of melting is clamp-oned again continuously by the second extruder, one is closely fused into through latter two tubular lobes of pinch roller rolloff, two tubular lobes weldings form the hollow reinforced rib of pipe outer wall, the fusion position, side of two tubular lobes is formed and strengthens internal-rib.There is following shortcoming in this technique: this hollow reinforced rib is all formed by plastic shaped band, and like this, the outer ripple shape plastic pipe structure-wall pipe material after shaping has very large weight, is not easy to transport.
And the following shortcoming of ubiquity in common winding bellows: 1) because bellows is softer, at the parcel melten gel after being rolled by pinch roller that is heated, the cross section of bellows becomes oval, the ratio between the width of hollow reinforced rib and height is caused to be greater than 1, reduce the ring stiffness of outer ripple plastic winding structure wall pipe, reduce the integral bending of wall pipe; 2) being heated and rolling rear distortion due to bellows, the height of the hollow reinforced rib of this wall pipe can only reach 6 ~ 8% of wall pipe diameter.
Therefore, be necessary to provide a kind of outer ripple shape plastic pipe structure-wall pipe material with hollow reinforced rib, to overcome above-mentioned technique and structural various shortcoming.
