The utility model provides a camber strip can the spiral winding mode, presss from both sides the outer ripple type tubular product of steel ribbing plastics through fused formation of melten gel, when having guaranteed that the bellows has good ring rigidity and good pipe clay combined action, owing to the cold rolling cloth of taking has the through -hole, has strengthened the steel and has moulded the adhesive strength, has also lengthened steel band corrosion resistance greatly, has more guaranteed the ring rigidity of tubular product.
Description
Technical field
This utility model relates to corrugated tube processing technique field, specifically a kind of folder steel ribbing plastics outward corrugated tube arc band.
Background technology
There is folder steel reinforcement hollow and strengthen outer ripple plastic winding structure wall pipe, owing to having good pipeclay combined effect and stronger ring stiffness, anti-corrosive properties, and be widely used in municipal administration blowdown, during wastewater from chemical industry collection conduit is built.
The manufacture of the outer ripple plastic winding structure wall pipe at present with hollow reinforced rib generally has three kinds.
Mode one: first squeezed the melted bar plastic sheet material of plastic extrusion by first, then make this sheet material be spirally wound on side by side regularly on the circular forming cylinder equipped with many little roller bearings of active rotation continuously.Extruded the trapezoidal tubulose reinforced pipe of section by another extruding machine simultaneously, with same spiral winding mode cross-pressure overlapping the slot position of each threaded plastic sheet neighboring edge on tube wall after water cooled Vacuum shaping, trapezoidal tubulose reinforced pipe bottom surface is suitably heated, simultaneously because plastic sheet is in semi-molten state, after the rolling of pinch roller, the bar plastic sheet material that tubulose reinforced pipe muscle and two-layer overlap mutually fuses together, and is formed and has the outer ripple plastic winding structure wall pipe that hollow is strengthened.
But, there is following defect in this technique；(1) owing to being wound around after the cooled sizing of reinforcement pipe, determining its height can not be too big, so the tube wall the moment of inertia after molding is less again；(2) adhesive strength of reinforcement tube and tube wall also is difficult to ensure, as too low in threaded plastic sheet temperature, then bonding difference.As temperature is too high, bar plastic sheet then can drop from forming cylinder, crumples and is difficult to control to molding.(3) because of this technique existing defects, cause tubing complete bonding after, the two sides of reinforcement pipe leave slot all the time, stress is caused to concentrate, when ambient temperature alternate, face of weld progressively can be ftractureed by slot, easily causes tube wall and separates with reinforcement pipe and collapse.
Mode two: extruded both sides, bottom surface respectively with the mutual welding special-shaped rectangular tube with suitable concaveconvex shape fin by the first extruding machine, this profile shapes is after cold water vacuum cooled is shaped, it is spirally wound on forming cylinder, again by the adhering resin that the second extrusion is melted, roll through pinch roller and bond together.
This technique suffers from the drawback that；Pipe ring stiffness is low, and adhesive strength is not high, and tubing integral bending is poor.
Mode three: satisfactory plate-like cold-rolled strip is passed through oil removing, after cleaning, utilize extruder to be injected by melted special bonding resin and reach the particular manufacturing craft that requirement cold-rolled steel was brought into, be stained with the steel band of resin water cooled but after, steel band top layer forms certain thickness resin protective layer, again by the steel band of matcoveredn by forming machine progressively molding, reach to produce helical form reinforcement required by pipe diameter by bending machine, helical form reinforcement on tube-conveyer, inside and outside wall is extruded threaded plastic lamellar by two separate extruders respectively, on tube-conveyer in circular drum autorotation process, inwall plastic sheet, reinforcement, outer wall plastic sheet fuses together, define the outer ripple plastic structure-wall pipe material that hollow steel band is strengthened.
This technique suffers from the drawback that；Because of reinforcement when this tubing produces, the fusion of inside and outside wall is all complete at synchronization, and temperature control requirement is higher, is mutually bonded and is difficult to control, and temperature is low, then bonding loosely, temperature height, bar plastic sheet is difficult to shape.Owing to steel band reinforcement is ribbon, it is spaced between inside and outside wall, in certainly will have impact on, outer wall fusion intensity.In addition steel band, plastic expansion rate difference, the change of temperature also have impact on pipe workpiece quality.In use easily causing delamination splitting, folded steel band belongs to banding, and Corrosion Protection is poor, there is pipeline and collapses risk.
Therefore, it is necessary to provide the Novel belt material of a kind of outer ripple plastic winding structure wall pipe with hollow reinforced rib, fundamentally to overcome the various shortcomings existed in above-mentioned existing band.
Summary of the invention
In order to solve above-mentioned technical problem, this utility model provides one folder steel ribbing plastics outward corrugated tube arc band.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of folder steel ribbing plastics outward corrugated tube arc band; including cold rolling strap; the middle part of described cold rolling strap is the inner groovy extended along cold rolling strap length direction; the dual-side of cold rolling strap is the plane sideband in same level; cold rolling strap is uniformly provided with some through holes; being attached to one layer of plastic protective layer on the outer surface of cold rolling strap, described plastic protective layer is positioned at the part of inner groovy and is provided with a cavity, is provided with the ribs of the horizontal plane being perpendicular to plane sideband place in described cavity.
The shape of cross section of described inner groovy be semicircle, triangle, rectangle, trapezoidal in one.
Described cold rolling strap is cold rolling bright finish soft metal band.
The beneficial effects of the utility model are:
The camber band that this utility model provides can spiral winding mode, the outer ripple type tubing of steel ribbing plastics is pressed from both sides through fused formation of melten gel, ensure that corrugated tube have good ring stiffness and good pipeclay coefficient while, owing to cold rolling strap being furnished with through hole, enhance steel and mould adhesive strength, also substantially prolongs steel band corrosion resistance, more ensure that the ring stiffness of tubing.
