Example Embodiment

[0014] combine figure 1 Taking the three-way pipe joint part as an example, the specific manufacturing method of the present invention is described:

[0015] First cut the straight pipe to a fixed length ( figure 1 a), pour the heated and melted low-melting medium such as industrial vaseline into the tube ( figure 1 b); cooled to form a solid, both ends can be sealed with a plastic (such as polyethylene) film with holes in the middle; then the pipe wall (preferably a PTFE film with a low coefficient of friction) is wrapped with a plastic film ( figure 1 c), put into a forming die; at least one of the two punches has a hole in the center. When forming, the punch squeezes the tube filled with the low-melting medium during the feeding process, which not only feeds the tube, but also automatically generates internal high pressure by extruding the low-melting medium, so that the tee parts are formed. The punch tip has a tapered step ( figure 2 shown), squeeze into the tube dur...

Abstract

A technology for manufacturing the jointer of multi-way pipe includes cutting a through pipe by needed length, filling the fused low-smelting-point medium in the pipe, cooling to become solid, sealing both ends by the plastic film with central hole, wrapping the pipe surface by plastic film, putting it in shaping die, and using two punch heads to press the both ends of pipe to become said jointer.

Description

technical field [0001] The invention belongs to a manufacturing method of a multiway metal pipe joint. Background technique [0002] Multi-way metal pipe joints include three-way, four-way and other pipe joint parts. They are commonly used industrial pipe fittings and are widely used in the transmission of liquid and gas. Metal multi-way pipe joints are generally manufactured from straight pipes through special equipment and molds. During the manufacturing process, a medium capable of transmitting deformation force is required inside the pipe for forming and preventing wrinkling. There are mainly two types of existing metal multi-way pipe joint manufacturing technologies: 1) one needs to be filled with rubber medium. By axially extruding the pipe filled with rubber medium in the die, the straight pipe is deformed into a multi-way pipe joint under the combined action of axial feeding and the pressure generated by the extruded rubber. The disadvantage is that due to the poor...
