Low-friction conveying channel and forming method thereof

Abstract

The invention discloses a low-friction conveying channel and a forming method thereof. The conveying channel consists of a support bottom plate and face sections, wherein the support bottom plate is provided with a support frame of the conveying channel along a conveying path; the face sections are positioned on the support bottom plate and are long strip sections with the same section shape and size; concave-convex grooves, which are rectangular grooves, dovetail grooves, semi-dovetail grooves, T-shaped grooves or sawtooth grooves, are formed on the side faces of the face sections; the internal surface of the conveying channel is formed by splicing the face sections; and the face sections are made of materials with low surface friction coefficient, such as ultrahigh molecular weight polyethylene and polytetrafluoroethylene. The problem that a large conveying channel is difficult to process is solved; due to a double-layer structure, an outer layer still can be normally operated when an inner layer is severely damaged, and great accidents are avoided; and the low-friction conveying channel is conveniently subjected to regular safety inspection and maintenance and replacement, and the reliability and safety of the conveying channel are greatly increased.

Description

technical field [0001] The invention relates to a conveying channel and a forming method thereof for transporting materials in various industries, in particular to a conveying channel and a forming method thereof for wear-resistant and low-friction applications. Background technique [0002] Conveying channels are often used for long-distance transportation of materials, and are often found in ports, docks, mines, coal mines, grain depots and other occasions. The conveying channel can transport pulverized coal, slag, mud, oil, grain, etc. over a long distance. Usually, this conveying channel is made of steel. The steel plate is processed by hot rolling and cold rolling to make conveying channels with different cross-sectional shapes, and then corresponding post-processing processes are carried out according to different usage occasions. Like transporting oil and mud, closed channels are often used, and semi-closed channels are often used to transport large particles such as...

AI Technical Summary

Problems solved by technology

Due to its extremely high relative molecular weight, high melt viscosity, low flow rate, and very difficult molding processing, the current molding methods of this material are mainly compression molding and plunger extrusion molding. The existing processing technology and equipment are still It cannot meet the processing and manufacturing of large-scale and complex parts. At present, these two materials are limited to the extrusion molding of small plates, sheets or rods.
