Embodiment Construction

[0027] In order to achieve the above object, the present invention adopts the following technical solutions: a bellows processing method, the processing method comprising:

[0028] a. Stirring and mixing: Add polyethylene plastic and foaming agent into the mixing drum for stirring and mixing;

[0029] b. Dissolution: Put the stirred and mixed raw materials into the extruder for dissolution;

[0030] c. Molding: Put the dissolved raw materials into the mold for solidification and molding;

[0031] d. Rinse: use cold water to rinse the formed bellows;

[0032] e. Cutting: use bellows cutting equipment to cut the washed bellows;

[0033] The dissolving operation is to put the raw material into the extruder, raise the temperature in the extruder to 230° C., and then extrude it from the extruder to form a molten state.

[0034] The flushing operation is to place the formed bellows in the fountain for flushing with water, and move the bellows back and forth under the nozzle of th...

Abstract

The invention discloses a corrugated pipe processing method. The corrugated pipe processing method comprises the steps that stirring and mixing are carried out, wherein polyethylene plastic and a foaming agent are added into a stirring drum for stirring and mixing; dissolving is carried out, wherein the stirred and mixed raw materials are put into an extruder to be dissolved; molding is carried out, wherein the dissolved raw materials are put into a mold for solidification molding; rinsing is carried out, wherein cold water is used for rinsing a molded corrugated pipe; and cutting is carried out, wherein a corrugated pipe cutting device is used for cutting the rinsed corrugated pipe. The method is simple to implement, the corrugated pipe can be sufficiently cooled during cutting, and the condition that the production quality of the corrugated pipe is influenced by corrugated pipe notch melting caused by too high temperature generated during cutting of the corrugated pipe is avoided.

Description

technical field [0001] The invention belongs to the field of bellows processing, and in particular relates to a bellows processing method. Background technique [0002] High-density polyethylene (HDPE) 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. However, in the traditional bellows processing method, the temperature at the incision of the bellows will increase when the bellows is cut. , so that the incision of the bellows melts, thereby affecting the production quality of the bellow...
