Problems solved by technology

However, the inventor found that in the process of conveying the slurry, the galvanized layer or the plastic-coated layer has poor wear resistance and is easy to fall off, causing the steel to be directly exposed to the medium. Due to corrosion and wear, the iron welding tee is accelerated. Rapid damage to pipe fittings
[0005] 2. Ordinary injection molding tee, because the material is made of PE and other materials, because of its low material strength, it can withstand higher pressure by thickening the pipe fittings, but it cannot meet the wear resistance
The iron tee of the lined PE wear-resistant pipe was completed, but the inventor found that the internal PE pipe was easily damaged by welding, resulting in complicated processing and high cost, and the PE pipe was not fully combined with the iron welded tee, and the axial resistance pull ability is weak

Abstract

The invention relates to a machining die, machining device and method for a lined wear-resisting layer of an iron three-way pipe fitting. The machining die comprises a first component, a second component and a third component; the first component can be fixed to one end of a three-way pipe fitting main pipe in a sealed mode and is provided with a first mandrel capable of coaxially stretching intothe three-way pipe fitting main pipe, and the second component can be fixed at the other end of the three-way pipe fitting main pipe in a sealed mode and can keep a set distance from the end surface of the first mandrel; and the third component can be fixed to the end part of a three-way pipe fitting branch pipe in a sealed mode and is provided with a second mandrel capable of coaxially stretchinginto the three-way pipe fitting branch pipe, and the end part of the second mandrel can make close contact with the outer mandrel face of the first mandrel. The die is convenient to machine and simple in structure, and a machined wear-resisting layer is not prone to fall off.

Description

technical field [0001] The invention relates to the technical field of high-pressure slurry conveying equipment, in particular to a processing mold, processing device and method for an iron tee lining wear-resistant layer. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the field of high-pressure slurry transportation, various forms of pipelines have emerged to solve difficult problems such as high pressure and wear resistance, but in terms of pipe fittings, the problem of combining high pressure and wear resistance has not been able to be solved. The tee can only unilaterally solve the characteristics of high pressure or wear resistance. for example: [0004] 1. Ordinary iron welding tees, the common anti-corrosion methods are galvanized or plastic-coated, processed with steel, and the pipe body has high strength. When transporting pure liqu...
