Forged Flange Process And Forged Flange Processing Procedures

Forged flange process and forged flange processing procedures

Free forging is a processing method that uses impact or pressure to freely deform metal in all directions between the upper and lower anvil surfaces. Compared with casting blanks, free forging eliminates the defects of shrinkage cavity, shrinkage porosity, pores, etc., so that the blank has higher mechanical properties. The shape of the forging is simple and the operation is flexible. Therefore, it is particularly important in the manufacture of heavy machinery and important parts. Free forging includes two types: manual forging and mechanical equipment forging. Its existence plays a very important role in modern industrial production of heavy machinery. The style and size of the formed forgings are determined by the skill level of the operators. Free forging machinery and equipment are divided into two categories: forging hammers and hydraulic presses. The forging hammers used in production include air hammers and steam-air hammers. Some factories also use spring hammers, splint hammers, lever hammers and wire hammers with simple structure and low investment. The hydraulic press deforms the blank by the static pressure generated by the liquid, which is a way to produce large forgings.

The process flow of free forging flanges and the processing procedures of forging flanges It is gradually forged through some basic deformation processes. The basic processes of free forging are upsetting, deep drawing, punching, bending and cutting. The following are some procedures for forging flanges.

1. The forging process in which the blank is bent at a certain angle or shape.

2. The forging process of cutting and dividing the blank or cutting off the material head.

3. Upsetting refers to the process of forging the original billet in the axial direction, reducing the height of the billet and increasing the cross section. This process is often used for the forging of gear blanks and other disc forgings. Upsetting can be divided into full upsetting and partial forging.

4. A forging process in which a part of the billet rotates at a certain angle relative to the other part.

5. Drawing is a forging process that increases the length of the blank and reduces the cross-section. It is usually used to process the blank of shaft parts, such as lathe spindles and connecting rods.

6. Punching A forging process in which a punch is used to punch through holes or no through holes on the blank.
