Folding caused by forging deformation
There are discontinuous and boss-shaped forgings in the upper module. After multi-fire forging, the die forgings are usually deformed to varying degrees due to factors such as beating during operation and punching and trimming. In the next fire die forging, the hammering center of the previous fire is the same as this time, but the formed bosses cannot be completely placed in the upper mold cavity, and a certain edge boss of the die forging will be Folding phenomenon occurs, and the more treatment measures, the higher the occurrence rate of folding and the more serious the degree. Therefore, in the die forging process, the number of fires should be minimized, and one-fire forming should be achieved as much as possible.
