Problems solved by technology

Since HDPE large-diameter double-wall corrugated pipe is a new product in the plastic pipe industry, in the actual production process of its flaring technology, if the interlayer gas cannot be completely discharged, the bell mouth will not be attached, which will affect the quality of the pipe and seriously It will cause the whole pipe to be scrapped, so we introduce an online expansion method for HDPE large-caliber double-wall corrugated pipe

Abstract

The invention discloses an HDPE large-caliber double-wall corrugated pipe online flaring method. The HDPE large-caliber double-wall corrugated pipe online flaring method includes the following steps that S1, a formed flaring module is arranged, and flaring module bodies with vacuumizing holes and exhausting needles are arranged; S2, the flaring module is adsorbed on the outer wall of a corrugatedpipe, and the outer wall of the corrugated pipe is adsorbed onto the inner wall of the flaring module in a vacuumizing method; S3, the inner wall of the corrugated pipe is attached to the outer wall of the corrugated pipe, so that the inner wall of the corrugated pipe is attached onto the outer wall of the corrugated pipe in a manner of increasing gas pressure; and S4, exhausting and cooling forming are performed. In the HDPE large-caliber double-wall corrugated pipe online flaring method, firstly, the formed flaring module is arranged, and the flaring module is adsorbed on the outer wall of the corrugated pipe; then the inner wall of the corrugated pipe is attached to the outer wall of the corrugated pipe; finally, methods such as exhausting and cooling forming are performed; and the outer wall of the corrugated pipe and the inner wall of the corrugated pipe are effectively attached closely, HDPE large-caliber double-wall corrugated pipe online flaring is completed, interlayer gas isdischarged due to a needle hole exhausting method, and the outer wall of the corrugated pipe and the inner wall of the corrugated pipe are free of a horn mouth shape during attaching.

Description

technical field [0001] The invention relates to the technical field of plastic pipe bellows expansion, in particular to an online expansion method for HDPE large-diameter double-wall bellows. Background technique [0002] Plastic pipes are generally made of synthetic resin, that is, polyester, added with stabilizers, lubricants, plasticizers, etc., and extruded in a pipe making machine by the "plastic" method. Mainly used for water supply system piping, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation in housing construction; plastic pipes are divided into thermoplastic pipes and thermosetting plastic pipes. kind. There are thermoplastic pipes, such as polyvinyl chloride pipes, polyethylene pipes, polypropylene pipes, polyoxymethylene pipes, etc.; there are phenol plastic pipes that are thermosetting. [0003] At present, the gap between the technical level of domestic plastic pipes a...
