Carbon steel flange

Carbon steel flanges are blank in the axial direction upsetting , forging horizontal projection mostly symmetrical shape. Select forging step when forming their degree of difficulty is divided into: ordinary forgings, forging deep high wheels and so on. Upsetting cylinders by removing the oxide scale on the blank , and then rising slightly upsetting the billet-tipping , remove the end surface of the oxide. Hydraulic tube fittings billet diameter of more than spoke , reaching the middle of the rim is appropriate, so can not produce at the hub folded and filled with large diameter carbon steel flanges , forging hammer on a single furnished no less upsetting station circumstances , can be two joint forging hammer . A hammer upsetting, another final forging hammer , forging easy as full , upsetting the final forging diameter as close as possible , so that in the final forging billet steel flanges in the positioning accuracy and can avoid collapse . In forging batch is small and easy to fold out of the case , but also directly in the final forging die bore in upsetting and final forging . This method should be used with caution because of the lower die life , and pay special attention to the removal of oxide . High wheel forgings used in deep step is: upsetting, upsetting shaping , final forging . In order to make the final forging billet in the mold chamber for easy positioning , is conducive to the hub is full , an increase of upsetting step , pre- forging a concave hole , flip after the final forging forgings to ensure full , or to avoid collapse , the need to improve the carbon flange flow conditions using pre blacksmith step Hoop larger pieces , such as no pre-forging , may be folded . Pre- forging , molding conditions improved . But in a hammer is sometimes arranged not open , you need to use two joint forging hammer . For these forgings, other devices can also be prepared in advance, the ring blank , and then the final hammer forging . For a high narrow bead of forgings, forgings in order to ensure full , but also uses pre-forging . As a diesel locomotive forgings forging process , the convex portion is placed on the mold in order to facilitate full , forgings increased lower central oblong craft boss , so to be positioned Hydraulic adapters die forgings . When forging flat , width is large, blank after flattening pan into the final forging of squash, entrapment , and then into the final forging broad face examples . For large changes in forging cross-section , can be shoulder press step . The flange cover flange fork forgings forging process . Since forging four larger width , and in order to make the blank after entrapment in the final forging die bore easily locate pendulum steady, not flip blank after entrapment , pan set man final forging . Upsetting The purpose is to make end formation , to avoid the folding and descaled . This is upsetting flange cake different. Full of difficult pre-forging forgings should be considered . Cylindrical gears for heavy duty vehicle active examples . Forging large diameter flange portion , a small thickness , the module can be arranged in the case of the use of pre- forged flange to improve flow conditions , help
