Processing Flow of Disk-shaped Forgings

Disk-shaped forgings are often also called short-axis forgings. According to the difficulty of forming, their processing flow can be roughly divided into the following three different situations: ordinary forgings, high-hub deep-hole forgings, and high-rib thin-walled complex forgings. Generally speaking, their processing flow mainly covers key steps such as upsetting, vertical upsetting to remove the scale, and final forging. Next, let's have a more detailed and comprehensive understanding of the detailed elaboration in this regard.

1. Processing flow of ordinary disk-shaped forgings: Such forgings, such as gears, flanges, cross shafts, etc., have relatively simple and clear shapes. In the actual processing process, the operation of upsetting is first used to effectively remove the scale on the cylindrical surface of the blank, and then the blank is turned 90° upright and gently upset to remove the scale on the end surface. The diameter of the blank after upsetting treatment is generally most suitable when it exceeds the spoke and can extend to the middle of the rim. Because of this treatment, on the one hand, it can effectively avoid the occurrence of folding, and on the other hand, it can ensure that the hub is fully filled. It is worth noting that if the diameter of the disk-shaped forging is too large to reasonably place the upsetting table on one forging hammer, in this case, two forging hammers can be flexibly used to forge cooperatively. Specifically, one hammer is responsible for the upsetting work, and the other hammer mainly undertakes the final forging task. Moreover, on the important premise that the forging can be filled without being affected, the upsetting diameter should be as close as possible to the diameter required during final forging. In this way, not only can the positioning of the blank during final forging be accurate, but also the undesirable phenomenon of folding can be successfully avoided.

2. Processing flow of high-hub deep-hole disk-shaped forgings: During the specific processing of this type of forging, in order to facilitate the accurate positioning of the blank during the final forging of the neck and to fully fill the hub, the key working step of upsetting forming is specially added. Firstly, a concave hole is pre-forged, and then after turning it 180°, the final forging operation is further carried out.

3. Processing flow of high-rib thin-walled disk-shaped forgings: In order to effectively ensure that the forging can be fully filled or to avoid the problem of folding, it is necessary to optimize and improve the metal flow conditions for this type of forging, so the use of the pre-forging step is crucial. Especially for those ring-shaped parts with a large diameter, if the pre-forging operation is not carried out during the processing, there is a high possibility of the undesirable condition of folding. After pre-forging, the forming conditions will undoubtedly be significantly improved. However, in actual operation, sometimes it is difficult to reasonably arrange the related working steps on one forging hammer. At this time, it is necessary to forge by combining two forging hammers. What specific contents does the processing flow of disk-shaped forgings include? The above elaboration is the relevant detailed introduction in this regard. Sincerely hope it can be helpful to everyone and provide valuable reference and reference for related processing operations.
