Commonly used forging equipment for flanges

Commonly used forging equipment for flanges

Commonly used die forging equipment includes die forging hammers, hot die forging presses, flat forging machines and friction presses.
In layman's terms, forged flanges are of better quality and are generally produced by die forging, with fine crystal structure and high strength, and of course the price is more expensive.
Both cast flanges and forged flanges are common manufacturing methods for flanges, depending on the strength requirements of the parts to be used. If the requirements are not high, you can also choose to turn flanges.

The basic process of flange forging

Die forging process: blanking, heating, pre-forging, final forging, punching and connecting, trimming, quenching and tempering, shot peening. Commonly used processes include upsetting, drawing, bending, punching, and forming.

Flange forging

The full name is model forging, which is formed by placing the heated blank in a forging die fixed on a die forging equipment.

Bending, twisting and cutting of flanges

A forging process in which a blank is bent into a certain angle or shape.
A forging process in which one part of the blank is rotated by a certain angle relative to the other part.
The forging process of dividing the blank or cutting off the material head.

Free forging and punching

Pulling is a forging process that increases the length of the blank and reduces the cross-section. It is usually used to produce shaft blanks, such as lathe spindles and connecting rods.
A forging process in which through holes or non-through holes are punched out on the blank with a punch.

Flange cutting flange

Directly cut the flange with the inner and outer diameter and thickness of the flange on the middle plate, and then process the bolt holes and waterline. The flange produced in this way is called a cut flange, and the maximum diameter of this type of flange is limited by the width of the middle plate.
