The basic process of free forging: During free forging, the shape of the forging is gradually forged from the blank through some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.
Butt welding alloy flanges are also called high neck flanges or big tail flanges. Alloy flanges are a type of pipe fittings. They refer to flanges with necks and round pipe transitions that are butt welded to the pipe. The flange is not easy to deform, has good sealing, and has a wide range of applications. Butt welding flanges are suitable for pipelines with large pressure or temperature fluctuations or high temperature, butt welding alloy flanges, high pressure and low temperature pipelines. The advantage is that the price is relatively cheap. Butt welding alloy flanges are nominal The pressure does not exceed 2.5MPa; it is also used on pipelines that transport expensive media, and the nominal pressure is around PN16MPa.
1. Upsetting Upsetting is the process of forging the original blank in the axial direction to reduce the height and increase the cross section. This process is often used for forging gear blanks and other disc-shaped forgings. Upsetting is divided into two types: total upsetting and partial upsetting.
2. Stretching Stretching is a forging process that increases the length of the blank and reduces the cross-section. It is usually used to produce blanks for shafts, such as lathe spindles and connecting rods.
3. Punching A forging process in which through holes or non-through holes are punched out on the blank with a punch.
4. Bending A forging process in which the blank is bent into a certain angle or shape.
5. Twisting A forging process in which one part of the blank is rotated by a certain angle relative to the other part.
6. Cutting The forging process of dividing the blank or cutting off the material head.
