Double-wall corrugated pipe production equipment and double-wall corrugated pipe production method

Abstract

The invention discloses a production device of a double-wall corrugated pipe. The production device comprises a protection shell, an installation plate and a press roller, wherein the protection shellis fixedly installed on the base; a rotatable cylinder is installed in the protection shell in a rotatable manner; and the installation plate is fixedly installed on one end of the rotatable cylinder, and the other end is uniformly connected to multiple connecting plates along the peripheral direction. Outside of the corrugated pipe is heated by electric heating wires inside two press plates; a limiting plate close to each of the press plates can be moved up and down under driving of a second electric telescopic pillar, so the corrugated pipe can be bent; and a bending radian can be adjustedaccording to a vertical motion height of the second electric telescopic pillar. In addition, through stretching and contracting of a first electric telescopic pillar, the upper limiting plate can be driven to move on the base; and the distance between the protection shell is changed, so the bending radian of a pipeline can be changed. The corrugated pipe can be comprehensively processed and can beapplicable to different working demands; and efficiency and quality of processing are better.

Description

technical field [0001] The invention relates to a double-wall corrugated pipe production equipment, in particular to a double-wall corrugated pipe production equipment and a double-wall corrugated pipe production method, belonging to the double-wall corrugated pipe production and application field. Background technique [0002] High-density polyethylene double-wall corrugated pipe is a new type of pipe with a ring-shaped outer wall and a smooth inner wall. It was first successfully 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 developed countries such as Europe and the United States. [0003] However, the existing double-wall corrugated pipe production equipment still ...
