Message: Upset Forging Machine|Used In Rebar Bending The Upset Forging Process Upset Forging is accomplished by holding pre-heated material between grooved dies, commonly known as 'grip dies’. Pressure is then applied to the end of the bar in the direction of its axis. The Heading Tool upsets the end of the bar by displacing the heated metal within a cavity. It’s not uncommon to have several upsetting operations on one die set, gradually forming the bar to its required shape. url:http://www.ztmineequipment.com
