The utility model relates to the field of hydraulic forming equipment of pipe fitting industry, which is a small and large size three-way pipe hydraulic water expansion forming machine.

Production of tee process: tube internal high-pressure forming technology usually uses the tube billet as raw material, by applying high pressure liquid pressure to the tube billet cavity, axial loading action, so that the plastic deformation occurs in the given mold cavity, the tube wall and the inner surface of the mold, so as to get the required shape parts of the technology.It is suitable for the stainless steel, copper, aluminum pipe three way pipe extrusion molding, the characteristics of the machine is equipped with a pair of transverse synchronous cylinder, in the cylinder axis is provided with a symmetrical mandrel.And can realize automatic production.

Application fields:Copper tube internal high pressure forming machine commonly used water swelling tee machine the series water expanding extrusion tee machine especially suitable for the hardware industry, aluminum, stainless steel, bronze, copper composite material of the straight tube, T tube, Y type pipe, L tube in the shape of a high pressure extrusion molding, such as one or more at a time, can also be applied to all kinds of copper products hollow parts, and in the manufacturing of complicated curved surface of the pipe fittings.Extruding medium is emulsified water which can be used back and forth, replacing the traditional rubber expansion and lead expansion, forming efficiency is fast and precision is high.

Cold drawing tee machine production process: cold drawing tee pipe device is the common equipment of cold drawing tee pipe fittings, the device includes metal bar, top pressure device, commutator, support, etc.;When the jack and the metal rod are pushed out, the pipe wall material naturally turns out to form the blank of the cold drawn tee.Then a certain length of the pipe section corresponding to the specifications is welded on the cold drawn tee blank formed by ejecting to produce the final product.

Installation method of cold drawing tee machine: first in the steel pipe with a hole opener, and then the mechanical tee card into the hole, the hole is surrounded by a sealing ring along the pipe wall seal.Mechanical three - wire connection and groove type two.When the mechanical tee is connected, the clearance between the mechanical tee and the hole should be checked, and all parts should be uniform, and then fastened in place;Mechanical tee hole spacing should not be less than 1m.

The hydraulic bulging of the tee is a forming process in which the branch pipe is bulged by the axial compensation of the metal material.That is the hot three - way cold extrusion technology.

(1) the common hydraulic press is used to inject liquid into the tube billet with the same diameter as the tee.(2) Through the two horizontal side cylinders of the hydraulic press synchronous movement of the extrusion of the tube billet, the volume of the tube billet becomes smaller after extrusion, and the pressure of the liquid in the tube billet increases with the volume of the tube billet becoming smaller. The three-way hydraulic bulging process can be formed once, and the production efficiency is high;The wall thickness of the head and shoulder of the tee has increased.
