Thermoplastic plastic hot-melting connection flanging control device and using method thereof

Abstract

The invention relates to the field of heating equipment with pressure or without pressure for plastic formation or connection, in particular to a thermoplastic plastic hot-melting connection flangingcontrol device and a using method thereof. The thermoplastic plastic hot-melting connection flanging control device comprises a cylindrical barrel body (1) and is characterized by further comprising amiddle section (2) and a handle (3); the large circular bottom surface of the middle section (2) is attached and fixed to the outer end surface of the barrel body (1); and the handle (3) is fixed tothe center of the inner end surface of the barrel body (1) through the inner end of a connecting rod (31). The using method of the thermoplastic plastic hot-melting connection flanging control deviceis characterized by sequentially comprises the following steps of 1, hot melting; 2, butt joint; 3, edge curling; and 4, withdrawing. The thermoplastic plastic hot-melting connection flanging controldevice is simple in structure and convenient to use and improves the water passing capability of a pipeline.

Description

technical field [0001] The invention relates to the field of pressure or non-pressure heating equipment used for plastic molding or connection, in particular to a thermoplastic plastic hot-melt connection flanging control device and a method of using the same. Background technique [0002] The traditional hot-melt connection construction method of plastic pipes is as follows, taking high-density polyethylene (HDPE) as an example: [0003] 1. Fix the HDPE pipe on the fixture of the hot melt machine, raise the temperature of the electric heating plate to 210℃, and operate the hydraulic device so that the two end faces of the two pipes to be butted are completely in contact with the electric heating plate for heating at the same time; [0004] 2. After the heating is completed, remove the electric heating plate and operate the hydraulic device again, so that the two melted end faces are attached under a certain pressure, squeeze each other on the attached surfaces, and lock the...

Problems solved by technology

[0006] Due to the hot-melt operation, the pipes form two inner and outer curls at the joint, and the curls can protect the hot-melt surface at the joint, but when the pipe with inner curls is used for drainage (especially for sewage pipes), It will cause garbage to be dragged on the inner curl of the pipe, which reduces the water flow capacity and is difficult to repair
