What should you pay attention to when producing flange forging?
Flange forging technology is a very complex technology. When producing flanges, it not only requires strict control of materials, but also requires effective control of production temperature, forging processes, etc. It is precisely because of the strict flange forging process that many people are interested in the process of producing flanges. Let us learn about the flange forging process together!
1. Flange forging process
The forging process generally includes cutting, heating, forming, and post-forging cooling processes. Forging technology includes free forging, die forging and tire film forging. The most important technology among them is free forging. Mastering the free forging technology can complete the production of flanges.
Free forging has the advantages of high production efficiency and large machining allowance. However, this tool is widely used for single-piece, low-volume forgings with simple general purpose and simple shapes. Free forging equipment includes pneumatic hammers, steam pneumatic hammers and hydraulic presses. Suitable for producing small, medium and large forgings respectively. Die forgings have high dimensional accuracy, small machining allowances, and more reasonable fiber structure distribution. The service life of parts can be further improved.
The basic process of free forging: In the free forging process. The shape of the forging is gradually forged into raw materials through some basic deformation processes. During the free forging process, it is necessary to strictly follow the process of stretching, extrusion, bending, and cutting, so as to ensure the normal production of flanges.
2. Flange production process
1. Upsetting is divided into complete upsetting and partial forging. Upsetting is the operation step of forging the blank along the axial direction, reducing the height of the blank and adding a cross section. This process is very suitable for forging gear blanks, so it is relatively rough. Of course, if there is no need for fineness, then it can be forged using this process. The parts can be used directly.
2. Stretching is a forging process. During the stretching process, the length of the raw material will become longer and the corresponding cross-section will become smaller.
3 Extrusion is a forging process in which the punch is pulled out of the through hole or does not pass through the raw material.
4. The forging process of bending material into a certain angle or shape.
5. Part of the material being forged is rotated at a certain angle relative to other parts.
6. The forging process of cutting off the billet or cutting off the scrap head.
There is a big difference between die forging and free forging. The raw materials that need to be heated are forged through die forging fixed on the die forging equipment. The basic process of die forging: blanking, heating, precision forging, front forging, and trimming. Common techniques for quenching, tempering and shot peening include upsetting, drawing, bending, punching, and forming. These are the basic steps in forging, and simple processing of materials can be completed using these steps.
The above is some knowledge about flange forging. This forging method is commonly used in flange products such as stainless steel flanges and carbon steel flanges.
