Abstract
The invention relates to an arc strip for a steel ribbed plastic outer corrugated pipe. The arc strip comprises a cold-rolled strip, wherein an inner groove extending in the length direction of the cold-rolled strip is formed in the middle part of the cold-rolled strip; the two side edges of the cold-rolled strip are both plane edge strips on one horizontal plane; multiple through holes are uniformly formed in the cold-rolled strip; a plastic protection layer is attached on the outer surface of the cold-rolled strip; a cavity is formed in the part, in the inner groove, of the plastic protection layer; and a reinforcing rib perpendicular to the horizontal plane where the plane edge strips are located is arranged in the cavity. The arc strip, provided by the invention, can be fused by sol to form the steel ribbed plastic outer corrugated pipe in a spiral winding manner, and guarantees the corrugated pipe to have excellent ring rigidity and excellent pipe-clay combined action; and as the through holes are formed in the cold-rolled strip, the steel plastic bonding strength is enhanced, the corrosion resistance of the steel strip is greatly improved, and the pipe ring rigidity is further guaranteed.
Description
Technical field
The present invention relates to bellows processing technique field, is a kind of folder steel ribbing plastics outward corrugated tube arc band specifically.
Background technique
There is folder steel reinforcement hollow and strengthen outer ripple plastic winding structure wall pipe, owing to there is good pipeclay acting in conjunction and stronger ring stiffness, anti-corrosive properties, and be widely used in municipal blowdown, during wastewater from chemical industry collection conduit is built.
The manufacture at present with the outer ripple plastic winding structure wall pipe of hollow reinforced rib has three kinds usually.
Mode one: first squeeze plastic extrusion melting bar plastic sheet material by first, 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.Extrude the trapezoidal tubulose reinforcement tube of section by another extruder simultaneously, with the overlapping the slot position of same spiral winding mode cross-pressure each threaded plastic sheet neighboring edge on tube wall after water-cooled vacuum sizing, trapezoidal tubulose reinforcement tube 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 tubulose reinforcement tube muscle and two-layer mutual overlap joint fuses together, and forms the outer ripple plastic winding structure wall pipe having hollow and strengthen.
But there is following defect in this technique; (1) because stiffening rib pipe is wound around after cooling and shaping again, determining its height can not be too large, so the tube wall moment of inertia after shaping is less; (2) bonding strength of stiffening rib tube and tube wall is also 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, crumple and be difficult to control shaping.(3) because of this technique existing defects, cause tubing complete bonding after, slot is left all the time in the bi-side of stiffening rib pipe, stress is caused to concentrate, when ambient temperature alternately changes, face of weld progressively can be ftractureed by slot, easily causes tube wall be separated with stiffening rib pipe and collapse.
Mode two: extrude both sides, bottom surface respectively with the special-shaped rectangular tube of a mutual welding with suitable concaveconvex shape fin by the first extruder, this profile shapes is after the sizing of cold water vacuum cooling, be spirally wound on forming cylinder, extrude the adhering resin of melting again by second, roll through pinch roller and bond together.
There is following shortcoming in this technique; Pipe ring stiffness is low, and bonding 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, the specialized mould utilizing extruder the special bonding resin injection of melting to be reached requirement cold rolled steel to bring into, be stained with the steel band of resin after water cooling, steel band top layer forms certain thickness resin protective layer, again that the steel band of matcoveredn is progressively shaping by forming machine, reached by Bending machines and produce helical stiffening rib required by pipe diameter, helical stiffening rib on tube-conveyer, inside and outside wall extrudes threaded plastic sheet by two separate extruders respectively, on tube-conveyer in circular drum autorotation process, inwall plastic sheet, stiffening rib, outer wall plastic sheet fuses together, define the outer ripple plastic structure-wall pipe material that hollow steel band is strengthened.
There is following shortcoming in this technique; Because of stiffening rib when this tubing is produced, inside and outside wall fusion is all complete at synchronization, and temperature control requirement is higher, mutual bonding very difficult control, and temperature is low, then loosely bonding, temperature is high, and bar plastic sheet is difficult to sizing.Because steel band stiffening rib is ribbon, be interposed 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 cause delamination splitting, folded steel band belongs to banded, and Corrosion Protection is poor, there is pipeline and to collapse risk.
Therefore, be necessary to provide a kind of Novel belt material with the outer ripple plastic winding structure wall pipe of hollow reinforced rib, fundamentally to overcome the various shortcomings existed in above-mentioned existing band.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of folder steel ribbing plastics outward corrugated tube arc band.
Technical problem to be solved by this invention realizes by the following technical solutions:
A kind of folder steel ribbing plastics outward corrugated tube arc band; comprise 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 evenly provided with some through holes; the outer surface of cold rolling strap is attached to one deck plastic protective layer, the part that described plastic protective layer is positioned at inner groovy is provided with a cavity, is provided with the strengthening rib of the horizontal plane 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 the cold rolling thin-skinned matter metal tape of light.
The invention has the beneficial effects as follows:
Camber band provided by the invention 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 bellows have good ring stiffness and good pipeclay coefficient while, due to cold rolling strap being furnished with through hole, enhance steel and mould bonding strength, also substantially prolongs steel band corrosion resistance, more ensure that the ring stiffness of tubing.
