Description

Technical Field

[0001] The utility model relates to the field of corrugated pipe production, in particular to a double-wall corrugated pipe cooling and forming device. Background Art

[0002] Double-wall corrugated pipe is a new type of lightweight pipe made of polymer material. It has the characteristics of light weight, good toughness and fast construction. Its outer wall is a corrugated convex structure, which enhances the ring stiffness of the corrugated pipe. It has low engineering cost and long service life. It is mainly used in large-scale water transmission, water supply, drainage, sewage discharge, exhaust, subway ventilation, mine ventilation and farmland irrigation with working pressure below 0.6MPa. Double-wall corrugated pipe needs to be cooled and formed after extrusion.

[0003] After searching, a Chinese patent announcement number CN212888816U was found, which discloses a modular cooling and forming device for a double-wall corrugated pipe. The patent has the advantages of simple structure, easy use and good cooling effect. By arranging a guide cover with a tapered structure inside the support tube, the cooling air generated by the air supply assembly is passed from the large mouth end of the guide cover into the interior of the guide cover and circulates in the inner cavity of the guide cover, so that the cooling air can be compressed during circulation, thereby improving the contact effect between the cooling air and the bellows and improving the cooling effect. At the same time, the cooling water inside the water storage chamber is used to exchange heat with the cooling air to ensure that the cooling air can continuously cool the bellows, further improving the cooling effect.

[0004] However, the position of the air guide cover in the above patent is fixed, so that the distance between the spray hole and the bellows is constant, which is not convenient for adapting to bellows with different diameters. Utility Model Content
