Equal diameter tee machine

Through to the oblique tee processes and analyzes common problems in the process of processing and research, to shape structure is relatively complex, the clamping difficult, difficult to ensure that problems such as accuracy, design a set of mould and cold extrusion with oblique tee tee machine using common fixture lathe processing, can effectively solve the above problems, and can improve the machining efficiency and to ensure the quality of parts processing, and has a certain universality, used for mass production.The same diameter tee machine is used for the formation of tee, the main power is hydraulic cylinder.

Equal diameter tee machine production steps are as follows: one step, steel plate rolling: forming steel plate according to thickness is divided into three areas of parallel arrangement of the end area, the middle area and the tail area, the middle area wall thickness is greater than the end area and the tail area wall thickness;Smooth transition;The second step, steel pipe forming welding, pipe making: the central region of the area in the pipe wall to form a thickening zone;The third step is opening and extrusion to form a workpiece with a three-way shape: opening holes in the thickened division line;The fourth step, integral processing: heat to 900℃ or so after heat preservation, and then integral.Eliminating the steel tube flattening and bulging process;The process greatly saves the manufacturing time and improves the production efficiency.After eliminating the process of flattening and bulging, the manufacturing molding time of the tee is greatly compressed, and the whole production cycle is greatly shortened.

Tee machine manufacturing process: as inside the tube filled with water medium: after sealed on both ends with 'high pressure cylinder filling medium water booster to the state of high pressure and constant (30 mpa to 300 mpa, according to the need to set), synchronous propulsion is greater than the tensile strength of the pipe on both ends and filling medium pressure, the pipe will be close to the plastic deformation flow model cavity wall outside, meet the requirements of cold extrusion tee machine molding process technology.Tee diameter from 21mm-630mm, wall thickness from 3mm-20mm we can do, hydraulic cold extrusion tee machine is suitable for carbon steel, stainless steel, and even part of alloy steel.

Tee forming machine technology is the use of tube billet as raw materials, through the tube cavity to apply liquid pressure and in the axial load effect, so that it in the mold cavity plastic deformation, tube wall and mold inner surface fit, so as to get the required shape parts of the molding technology.Difficult for small size of fillet, molding products tend to adopt sectional pressure forming, namely first complete the expansion pipe, with smaller pressure line into a large rounded corners, have maintained uniform wall thickness at this time, then the pressure increase, forcing fittings mold joint, the rounded materials tensile deformation, the tube wall thinning, finally get the tee.
