Production and processing equipment for double-wall corrugated pipe

Abstract

The double-wall corrugated pipe production and processing equipment comprises an extruding machine, a lining pipe is fixedly installed at the position of a discharging opening of the extruding machine and used for bearing a discharged formed pipe, the outer diameter of the lining pipe is matched with the inner diameter of a processed pipe, and the outer diameter of the lining pipe is matched with the inner diameter of the processed pipe. A pipe ring cutting mechanism is fixedly installed at the end of the side, away from the extruder, of the lining pipe, a corrugation forming mechanism is arranged on one side of the extruder, the lining pipe penetrates through the corrugation forming mechanism and extends to the other side of the corrugation forming mechanism, a pipe body is extruded through the extruder, the extruded pipe body is pulled to a pipe forming roller mold, and the pipe forming roller mold is used for forming the pipe body. A corrugated pipe forming device is used for pressing corrugations and completing the fixed-length cutting process, a supporting device is arranged in the middle of a pipe and has a conveying function, forming dies are arranged on the upper side and the lower side of the supporting device, and forming machining of the corrugations of the pipe is completed.

Description

technical field [0001] The invention relates to the technical field of pipe processing equipment, in particular to a production and processing equipment for double-wall corrugated pipes. Background technique [0002] Double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first developed in Germany in the early 1980s. After more than ten years of development and improvement, it has developed from a single variety to a complete product series. At present, the production process and application technology are very mature. Due to its excellent performance and relatively economical cost, it has been greatly promoted and applied in countries all over the world. Due to its excellent chemical stability, aging resistance and environmental stress cracking resistance, it has strong resistance to external pressure, low engineering cost, convenient construction, small friction coefficient, large flow, low temperature resistance an...

Problems solved by technology

[0003] However, during the processing of the above-mentioned pipes, the corrugated pressing of the outer surface of the pipes often adopts a rotary forming mold similar to a crawler, which can realize the transmission of the pipes and the forming of the pipes at the same time, but in actual processing. There is no supporting device inside, which may cause deformation of the pipe during the pressing process, or the heating temperature is too high, resulting in collapse and deformation of the pipe, etc.
