The Process of Stainless Steel Buttweld Cross bulge forming

Press the tube blank larger than the diameter of the cross to the size of the diameter of the cross, and open a hole in the portion of the stretching branch pipe;

The tube blank is heated, placed in a forming mold, and a die of the tensile branch tube is put into the tube blank;

The tube blank is radially compressed under the action of pressure, and the metal flows toward the branch pipe during the radial compression and forms a branch pipe under the drawing of the die.

The entire process is formed by the radial compression of the tube blank and the stretching process of the branch portion. Different from the hydraulic bulging four-way, the metal of the bulge formed cross branch pipe is compensated by the radial movement of the tube blank. Since the cross is compressed after heating, the tonnage of the equipment required for material forming is reduced. The bulge formed cross has wide adaptability to materials, and is suitable for materials of low-carbon steel, alloy steel, and stainless steel. Especially the large-diameter and thick-walled cross is usually used in this forming process.
