A kind of outer diameter sizing sleeve of plastic composite pipe with steel mesh skeleton

Abstract

The invention discloses an outside diameter sizing sleeve for a steel wire mesh skeleton plastic composite pipe. The sizing sleeve is provided with a sizing sleeve shell, a sizing sleeve core and a connecting flange, wherein the sizing sleeve core is arranged in the sizing sleeve shell; and the connecting flange is arranged at one end of the sizing sleeve shell. The sizing sleeve core is provided with a water inlet groove, a sealing groove, a vacuumizing hole and a cooling runner, wherein the water inlet groove is communicated with the cooling runner; and the inner side of one end of the sizing sleeve core is provided with a chamfered R surface through which the pipe enters the sizing sleeve. The sizing sleeve shell is provided with a water inlet and a vacuumizing port, wherein the water inlet is correspondingly communicated with the water inlet groove in the sizing sleeve core. The sizing sleeve has reasonable and scientific structure; the sizing sleeve is provided with an independent vacuumizing system and an independent cooling system and made of high-hardness stainless steel, and the inner surface of the sizing sleeve is not easily scratched by a steel wire, so that the sizing sleeve is more durable and has longer service life. The whole equipment is low in manufacturing cost, has great significance for improving quality of products, and is popular among enterprises in the industry all the time.

Description

technical field [0001] The invention relates to a steel mesh skeleton plastic composite pipe external diameter calibrating sleeve, which belongs to the technical field of composite pipe forming equipment. 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 the past ten years. It is a network structure formed by high-strength copper-plated steel wire winding and weaving left and right as the skeleton, high-density polyethylene as the base material (polyethylene is a special material for PE100 pipelines), and modified polyethylene---adhesive resin, It is a new generation of chemical building materials with pressure resistance, internal and external anti-corrosion formed by continuous and step-by-step extrusion compounding on the production line. The product specification is φ63~φ630mm, widely used in municipal water supply and drainage, petrochemical, e...

AI Technical Summary

Problems solved by technology

[0004] At present, the use of sizing sleeves in the plastic pipe industry is relatively common, but it is only limited to the use of traditional PE and PVC pipes; the use of sizing sleeves in the production process of steel mesh skeleton plastic composite pipes is currently only used for core pipe sizing. At present, there is no domestic use of sizing sleeves for outer pipe sizing, but the outer diameter sizing sleeves designed by us through independent research and development have been successfully tested in our company, and have been widely used in steel mesh skeleton plastic composite pipe products. The quality and appearance of the products produced after the outer diameter calibrating sleeve surpasses similar products without the outer diameter calibrating sleeve, and has won wide recognition in the market
