Causes of Folding Defects in Automobile Forgings

Forging manufacturers have many forging products, such as automobile forgings, railway vehicle forgings and train forgings. Each forging is processed through excellent production technology. Today, we will introduce the use of a material multi-forging die forging method. While we use this approach quite often, we cannot implement it under many constraints. Hebei forging manufacturers can only produce good forgings with proper environmental methods. As long as one method meets the requirements, the following methods cannot be used. For example, the weight of the forging is particularly large, the horizontal projection area of ​​the forging is large, the appearance of the forging is complex, the temperature range of the forging is small, the depth of the forging mold chamber is large, the deformation of the final forging is too large, and the number of billet making steps in the first-fire die forging is too large. Large ≥ 3. The use of forging equipment needs to be increased, and the use of forging equipment needs to be increased. Every processing of forgings requires us to cast forgings carefully, and the forging processing method carefully casts products to ensure our safety.

Folding defects, causes and pre-control methods of automobile forgings:

There are many closed parts in automobile forgings, the rib spacing is short, the rib spacing is thin, the rib spacing and the web thickness are large, and the surface of many parts is not processed. Due to the large number of ribs in automobile forgings, folding problems often occur at the joints of ribs and webs, ribs and edge strips during production. Folding on automotive forgings breaks its continuity because it weakens the part, or stress concentration and fatigue cracks occur during use, which greatly reduces the load-bearing capacity of the forging. Ribs are usually used to install rigid or link surfaces to prevent folding defect.
