Embodiment Construction

[0013] The present invention will be further described below in conjunction with the drawings and implementation process.

[0014] figure 1 Explain the basic composition of the sizing sleeve shell. The water ring 1 of the sizing sleeve and the inner core 2 of the sizing sleeve are inlaid in one body, and are connected with the vacuum sizing box by bolts through the bolt connection hole 6, and the water inlet hole 3 is connected with the cooling circulating water equipment of the external equipment. There is a cooling water chamber between the ring 1 and the inner core 2, so that the water chamber is filled with cooling water to cool the front section of the inner core of the sizing sleeve. At the same time, there is an annular groove at the front section of the inner core to increase the cooling area of ​​the inner core of the sizing sleeve by the cooling water. Drainage is carried out through the drainage hole 4, so that the cooling water in the water chamber is circulated. ...

Abstract

The invention relates to a steel wire mesh frame polyethylene composite tube external layer sizing sleeve. The steel wire mesh frame polyethylene composite tube external layer sizing sleeve is arranged and connected between a steel wire mesh frame polyethylene composite tube extruder head and a vacuum cooling sizing box, and comprises a sizing sleeve water ring, a sizing sleeve inner core and a connecting flange, the sizing sleeve inner core is inlaid in the sizing sleeve water ring, the sizing sleeve water ring is provided with water inlets and a water outlet, the sizing sleeve water ring and the connecting flange form one body, steel frame polyethylene composite tube production line external layer vacuum sizing box is connected through the flange, and the sizing sleeve water ring penetrates deeply into the vacuum sizing box. The steel wire mesh frame polyethylene composite tube external layer sizing sleeve has the advantages of simple structure and installation convenience, and allows the outer wall of the tube to be flattened and smooth through friction of the outer wall of the tube and the inner wall of the sizing sleeve inner core when the tube passes by the sizing sleeve. The appearance of the steel wire mesh frame polyethylene composite tube of different specification models can be completely improved by replacing different specification models of the sizing sleeve.

Description

technical field [0001] The invention relates to a pipe forming equipment, in particular to a sizing sleeve for the outer layer of a polyethylene composite pipe with a steel mesh skeleton. Background technique [0002] Steel mesh skeleton polyethylene composite pipe is a new type of high-tech and environmentally friendly chemical pipe that has emerged in China in recent years. HDPE) is a new type of pipe that uses high-performance HDPE modified bonding resin to tightly connect the steel wire skeleton with the inner and outer layers of high-density polyethylene. Widely used in oil fields, urban water supply, power plants, chemical and petrochemical enterprises, water companies, municipal gas, metallurgical mines, seawater utilization pipelines and other fields. [0003] At present, the use of sizing sleeves in the plastic pipe industry is relatively common, but it is only used in PE and PVC pipes. The use of sizing sleeves in the production process of steel mesh skeleton poly...
