Embodiment Construction

[0017] Example 1. The production specification is DN1000*DN800 STD (φ1016*9.53mm / φ813*9.53mm) tee fittings; that is, the material of the tee fittings is Q235, the wall thickness is 9.53mm, and the diameter D of the tee main pipe is 1016mm, d The diameter of the branch pipe of the tee is 813mm, the length C of the main pipe of the tee is 1498mm; the height M of the branch pipe is 711m;

[0018] (1) Select a piece of Q235 steel plate for cutting and blanking to obtain the upper tile material. The length of the upper tile material is L=1980mm, the width is B=1600mm, and the thickness is the same as that of the finished tee pipe fittings to be produced. The wall thickness is the same; use the rolling machine to roll the upper tile material into a U-shaped upper tile. The radius R of the U-shaped upper tile is 508mm, the height of the straight sides on both sides is 200mm, and the length of the U-shaped upper tile is 1600mm. ;

[0019] (2) Put the U-shaped upper tile into the furn...

Abstract

The invention relates to a production method for a three pipe fitting. The finished product of tee pipe fitting is produced by the following steps of: cutting one block of steel plate of the same material required by the tee pipe fitting to obtain an upper tile material and winding the upper tile material into a U-shaped upper tile; blistering and opening pores on the U-shaped upper tile and extruding a tee branch pipe at the pores; cutting one block of steel plate of the same material required by the tee pipe fitting to obtain a lower tile material and winding the lower tile material into a U-shaped lower tile; and finally splicing and welding the U-shaped upper tile and the U-shaped lower tile. The method has the advantages of greatly improving fluidity of medium, along with larger aperture of the produced tee pipe fitting and smooth transition between a main pipe and the branch pipe of the produced tee pipe fitting.

Description

1. Technical field [0001] The invention relates to a production method of a three-way pipe fitting, in particular to a tile-type production method of the three-way pipe fitting. 2. Background technology [0002] Tees are pipe fittings and pipe connectors, also known as pipe fittings or tee fittings, and tee joints, which are used at the branch pipes of the main pipeline; tees are divided into equal diameters and different diameters, and the connecting ends of equal diameter tees All parts are the same size; the size of the main tube of the tee with different diameters is the same, and the size of the branch pipe is smaller than that of the main tube. [0003] Tee is a kind of pipe fitting used at the branch of pipeline. For the manufacture of tees with seamless pipes or longitudinally welded pipes, there are currently three commonly used processes: hydraulic bulging, hot pressing forming, and welding forming. [0004] Using the hydraulic bulging process, the caliber of the...
