Abstract
The invention discloses a production method for high-rigidity steel strip reinforced polyethylene helical bellows. The production method comprises the following steps: winding sheets extruded by polyethylene resin to form an inner layer; roughening raw materials of steel strip, then coating plastic on the steel strip and uniformly coating adhesive resin on the surface of the steel strip; performing stress pre-eliminating, forming and bending process on the continuous steel strip coated by the adhesive resin, and bending the steel strip into approximate shape of the Greek alphabet 'Omega'; forming an outer layer by using polyethylene resin raw material; winding the steel strip between inner and outer layers of polyethylene resin by using the hot welding technology to finish splicing and compounding the inner layer, the plastic-coated steel strip and the outer layer; and cooling and forming, calculating length and cutting, checking finished products and putting the finished products in a storehouse. By adopting the technical scheme, the steel strip winding size and the curvature range are controlled, so that the diameter of the steel strip reaches the stable state, the springback stress of the steel strip is fully eliminated, the molding rate of the tubular product is improved, the splicing and compounding strength is ensured and the compounding quality of the tubular product is improved.
Description
Technical field
The invention belongs to the steel band reinforced polyethylene spiral ripple pipe field, especially relate to a kind of high rigidity steel band reinforced polyethylene spiral ripple pipe production method.
Background technology
Because steel band reinforced polyethylene spiral ripple pipe has high rigidity, high strength and the characteristics such as corrosion-resistant, wear-resistant and pliability is strong, therefore, its steel-plastics composite pipe as a kind of high performance-price ratio is widely used in the fields such as draining.The structure of steel band reinforced polyethylene spiral ripple pipe is: the polyethylene inner layer pipe that internal layer is continuous real wall, the outer winding of inner layer pipe is compounded with the coating steel band, outside inner tube layer and coating steel band, is compounded with outer layer of polyethene.And steel band needs to reach yield point through the moulding bending in the moulding BENDING PROCESS, guarantee that the steel ring diameter is in stable state.In the prior art, yield strength difference due to steel band, same degree of crook can not guarantee that steel band reaches yield limit, there is certain resilience stress in steel band, cause the tube forming difficulty, compound sticking is bad, easily layering, after moulding, there is certain residual stress in steel band, can't produce high rigidity steel band reinforced polyethylene spiral ripple pipe.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of high rigidity steel band reinforced polyethylene spiral ripple pipe production method, has especially pointed out the innovation of the pre-stress-removal technology of steel band.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of high rigidity steel band reinforced polyethylene spiral ripple pipe production method comprises the following steps:
(1) polyethylene resin feedstock is tested, the raw material be up to the standards is carried out to drying, the sheet material of then polyvinyl resin being extruded forms internal layer through being wound around;
(2) the steel band raw material is tested, the raw material be up to the standards is carried out to the texturing processing, then steel band is carried out to the plastic-coated processing, adhering resin is uniformly coated on to steel strip surface;
(3) steel tape of coated adhering resin is carried out to pre-stress-removal moulding bending process, bend to approximate " Ω " type;
(4) polyethylene resin feedstock is tested, the raw material be up to the standards is carried out to drying, then outer tube is extruded and formed skin;
(5) utilize the thermal welding technology, steel strip winding, between inside and outside two layers of polyethylene resin, is completed to internal layer and plastic-coated steel band and skin and completes bonding compound;
(6), through cooling and shaping, the long cutting of meter, complete the finished product warehouse-in after product inspection.
Further, the present invention, when steel band is carried out to pre-stress-removal moulding bending process, adopts and the corresponding moulding coefficient of processing technology according to the steel band of different brackets yield strength, and computing formula is as follows:
Wherein, D
markmean that the steel band yield strength is in 160～220MPa, the diameter of steel band bending forming; D
realwhile being illustrated in actual production, in steel band winding shaping technique, the diameter of steel band bending forming.
| Yield strength | The steel band flexibility | Moulding coefficient (%) |
| 160-190 | The hogging bending degree | －0.05～－2 |
| 190-210 | The positive curve degree | 0 |
| 210-220 | Super flexibility | 0.1～2 |
| >280 | Super positive curve degree | Approximately 3.5 |
Advantage and good effect that the present invention has are: owing to adopting technique scheme, when steel band is carried out to pre-stress-removal moulding bending process, employing bends to that spiral steel rib is wound around and welding during in polyethylene inner layer in the vertical appropriateness of steel band, carry out the control of steel strip winding size and flexibility scope, can guarantee that in control range the steel belt molding bending reaches yield point, the steel band diameter reaches stable state, fully eliminate the resilience stress of steel band, improved the ratio of briquetting of tubing, guarantee bonding compound intensity, improve the composite quality of tubing.
