Butt welding flange production method is the most common free forging butt welding flange and die forging butt welding flange these two forms, the following and you introduce the two production processes:
First, the basic process of free forging butt welding flange: when free forging, the shape of the forging is gradually forged into the blank through some basic deformation processes. The basic processes of free forging butt welded flange include upsetting, drawing, punching, bending and cutting.
1. Upsetting upsetting is the operation process of forging the raw billet along the axis to reduce its height and increase its cross section. This process is often used for forging gear billets and other disc-shaped forgings. There are two kinds of upsetting: full upsetting and partial upsetting.
2. Drawing length is the forging process that increases the length of the billet and reduces the section, which is usually used to produce shaft parts blank, such as lathe spindle and connecting rod.
3. The forging process of punching out through holes or through holes on the blank with punches.
4. Bending Forging process that bends the billet into a certain Angle or shape.
5. Twist the forging process that rotates one part of the blank at an Angle relative to another.
6. Forging process of cutting and dividing billet or cutting out head.
Second, die forging die forging is called model forging, and the heated blank is placed in the forging die fixed on the die forging equipment.
1. The basic process of die forging Die forging process: blanking, heating, pre-forging, final forging, punching skin, cutting edge, conditioning, shot peening. Common processes include upsetting, drawing, bending, punching and forming.
2. Common die forging equipment Common die forging equipment include die forging hammer, hot die forging press, flat forging machine and friction press.
Generally speaking, the quality of forged butt welding flange is better, generally produced by die forging, the crystal structure is fine, the strength is high, and of course the price is more expensive.
