Select high quality billet blanking, heating, forming, cooling after forging. The forging process includes free forging, die forging and die forging. During production with forging press,different forging methods are selected according to the quality and size of forgings and the number of production batches.
Basic process of free forging: in free forging, the shape of the forging is gradually forged into the blank through some basic deformation process. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.
Upsetting is the process of forging the blank along the axis to reduce its height and increase its cross section. This process is often used to forge gear billets and other disc-shaped forgings. Upsetting can be divided into two categories: overall upsetting and local upsetting.
Drawing out is a forging process that increases the length of the blank and reduces the section. It is usually used to produce the blanks of shaft parts, such as lathe spindle and connecting rod.
A forging process in which a punch is punched through or through a hole in the blank.
A forging process in which a blank is bent to an Angle or shape.
A forging process in which one part of the billet is rotated at an Angle to another.
The forging process of cutting and dividing the billet or cutting off the head.
Die forging is called model forging, in which the heated blank is placed in the forging die fixed on the die forging press equipment. Basic procedures: blanking, heating, pre-forging, final forging, blanking and blanking, trimming, tempering and tempering, shot peening.
