quality BL Flange manufacturers products The forging process generally consists of the following procedures, namely, selecting high-quality billets for blanking, heating, forming, and cooling after forging. Forging methods include free forging, die forging and membrane forging. During production, different forging methods are selected according to the quality of forgings and the number of production batches.

quality BL Flange manufacturers products Free forging has low productivity and large machining allowance, but the tools are simple and versatile, so it is widely used for forging single-piece and small-batch forgings with relatively simple shapes. Free forging equipment includes air hammer, steam-air hammer and hydraulic press, etc., which are suitable for the production of small, medium and large forgings.

1. Quality BL Flange manufacturers products The basic process of free forging: during free forging, the shape of the forging is gradually forged from the blank through some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.

2. Quality BL Flange manufacturers products die forging. The full name of die forging is model forging, and the heated blank is placed in the forging die fixed on the die forging equipment for forging.

3. Cutting the flange

Cut out the inner and outer diameter and thickness discs of the flange directly 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 to the width of the middle plate.

4. Coiled flange

quality BL Flange manufacturers products The process of cutting slivers with middle plates and rolling them into circles is called rolling, which is mostly used in the production of some large flanges.
