Another object of the present invention is to provide a kind of production method that adopts the double-walled spiral pipe of production equipment of the present invention.
In order to reach the foregoing invention purpose, the technical scheme that the production equipment of double-walled spiral pipe of the present invention adopts is:
A kind of production equipment of double-walled spiral pipe is connected to form successively by extruder, shaped device, cooling device, auxiliary hitch, cutter sweep and pipe discharging device, it is characterized in that described shaped device comprises spiral calibration sleeve and water jacket.
In the technique scheme, described spiral calibration sleeve is placed on the periphery of water jacket, and the spiral calibration sleeve is provided with ripple groove, and is provided with through hole on groove.
The technical scheme that the production method of double-walled spiral pipe of the present invention adopts is:
A kind of production method of double-walled spiral pipe is extruded pipe, shaped device shaping pipe structure, cooling, traction by extruder and is collected the production process of finishing pipeline, it is characterized in that the structure by spiral calibration sleeve and water jacket shaping pipe.
In the technique scheme, the helicitic texture of the outer surface by spiral calibration sleeve shaping pipe.Described spiral calibration sleeve is by the helicitic texture of vacuum adsorption molding pipe outer surface.
The production method of double-walled spiral pipe of the present invention is by the slippery inner surface of water jacket cooling forming tubing.
Operation principle of the present invention is:
Plastics are extruded through the extruder die head, the extruder die head is divided into two-layer, the outer pipe of outer extruding pipe material, the internal layer pipe of internal layer extruding pipe material, be provided with the space between skin and the internal layer, be used for blowing at extrusion, to cut apart internal layer pipe and outer pipe, outer pipe is by spiral calibration sleeve moulding helical corrugation shape outer wall, this is the through hole that has on the crest by the spiral calibration sleeve, adopt vacuum suction to be used for realizing, the internal layer pipe is by cooling jacket cooling forming smooth inner wall, and the ectonexine pipe merges at the trough place of helical corrugation shape.Enter cutter sweep and pipe discharging device by the traction through auxiliary hitch after the cooling device cooling behind the tube forming, after reaching the length that needs, cut, just finish the production process of a tubing after collecting by pipe discharging device by cutter sweep.
The contrast prior art, the present invention has following advantage:
The present invention is in conjunction with the advantage of solid wall pipe and winding pipe, main pipeline moulding is finished by spiral calibration sleeve and water jacket, its helical corrugation shape outer wall directly forms by the spiral calibration sleeve when the extruder extruding is produced, can realize continuous production, contrast existing direct extrusion molding solid wall pipe and utilize module moulding bellows, it is simpler that the present invention has structure, the reliable advantage of more convenient operation; Compare with the pipe intermediate adhesion tack coat that the ripple forming of existing winding corrugated pipe is extruded by two extruders, have according to the invention provides tubing that production method produces that ring stiffness is higher, the higher advantage of better, the anti-fracture strength of cross directional stretch performance.
