Embodiment
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
A Steel Skeleton polyethylene spirally enwound structure-wall tubular product, consists of inner wall layer 3 and outer wall layer 4, and inner wall layer is for to be spirally wound on drum die by sheet polyethylene band, and each adjacent ribbons edge continuous solid wall pipe that overlap joint fusion forms mutually successively.
Its innovation is: described outer wall layer becomes the steel band 2 of cross section Ω type to do skeleton by bending surely, polyethylene band is coated on this steel band outer surface and spiral winding forms in the formed evagination stiffening rib of inner wall layer outer surface, and this evagination stiffening rib spiral cross-pressure melts commissure in the overlap joint of each adjacent sheet shaped polyethylene strip edge of inner wall layer.Inner wall layer two ends are spirally wound on and on drum die, are formed respectively bellmouth 1 and socket 5 by sheet polyethylene band.
The crooked steel band that surely becomes cross section Ω type, on its base, both sides 6, be all shaped with the boring of continuous layout, when the polyethylene band of outer wall layer is coated on steel band outer surface, the polyethylene material of outer wall layer polyethylene band enters in the made boring 7 in bottom surface, steel band both sides, form one with the polyethylene material of the sheet polyethylene band of inner wall layer, stop strip deformation.The crooked steel belt framework that surely becomes cross section Ω type, surface uniform is coated with binding resin film outside, and this binding resin film makes strong bonded between the polyethylene band of outer wall layer and inner wall layer and steel strip surface.
Above-mentioned Steel Skeleton polyethylene spirally enwound structure-wall tubular product production method, the step of its production method is:
The utility model processing device used, as shown in Figure 4.
(1). take high-density polyethylene resin as main raw material(s), raw material is delivered in the first extruder 9 through vacuum feeder heat, plasticizing, homogenizing, through the first extruder runner and die extrusion sheet polyethylene band, and be equidistantly wound in drum die 10 surfaces, and each adjacent ribbons edge is overlap joint fusion mutually successively, form the inner wall layer of continuous solid wall pipe structure.
(2). in step sheet polyethylene band winding process (1), each adjacent sheet shaped polyethylene strip edge lap-joint by the first pressing wheel mechanism in the setting of drum die periphery after to the winding of inner wall layer carries out roll extrusion successively, makes its mutual melting and keeps continuous strand suitable.The first pressing wheel mechanism 11 and the fixed installation of the first extruder, the two synchronously moves axially along drum die 10.
(3). pretreatment bending becomes the steel belt framework of Ω type surely, continuous drilling on two bases of steel band, the outer surface of steel band evenly applies binding resin film, is delivered on drum die; Be specially: steel band first processes boring by punch press in steel band both sides, and bore diameter is 5mm～10mm, and the spacing of boring is 3～6mm, then molds cross section Ω type by milling train, makes it have the circular arc of base, both sides and epirelief, square, trapezoidal or triangular hill.
(4). adopt the second extruder 8 to squeeze out polyethylene band, with bending, surely become the steel band of cross section Ω type to do skeleton, polyethylene band is coated on steel band outer surface and spiral winding forms evagination stiffening rib in inner wall layer outer surface, and evagination stiffening rib spiral cross-pressure melts commissure in the overlap joint of each adjacent sheet shaped polyethylene strip edge, form the outer wall layer of body; When the polyethylene band of outer wall layer is coated on steel band outer surface, the polyethylene material of outer wall layer polyethylene band enters in the made boring in bottom surface, steel band both sides, forms one with the polyethylene material of the sheet polyethylene band of inner wall layer, stops strip deformation; Binding resin film makes strong bonded between the polyethylene band of outer wall layer and inner wall layer and steel strip surface.Steel band is to be synchronizeed and sent by the mouth mould of the second extruder with polyethylene band, makes its two combination; Or first steel band is wound in outside inner wall layer, polyethylene band covers steel band after being extruded by the second extruder again, makes its two combination.
(5). by the evagination stiffening rib after the 12 pairs of windings of the second pressing wheel mechanism in the setting of drum die periphery, carry out roll extrusion, make its each adjacent sheet shaped polyethylene strip edge overlap joint that blends into inner wall layer outer surface melt commissure.This second pressing wheel mechanism and the fixed installation of the second extruder, the two synchronously moves axially along drum die 10.
(6). employing the first extruder squeezes out sheet polyethylene band, and is equidistantly wound in drum die bellmouth and socket outer surface in rolling-operation, and the overlap joint fusion mutually successively of each adjacent ribbons edge, forms bellmouth and the socket of continuous solid wall pipe.
(7). after cooling and shaping, the demoulding, forms pipe finished.
Although disclose for the purpose of illustration embodiment of the present utility model and accompanying drawing, but it will be appreciated by those skilled in the art that: within not departing from the spirit and scope of the utility model and claims, various replacements, variation and modification are all possible, therefore, scope of the present utility model is not limited to embodiment and the disclosed content of accompanying drawing.
