China stamping dies, progressive dies, transfer dies, sheet metal parts supplier, manufacturer----Higrade(Qingdao) Moulds & Products Co., Ltd.)

The deep drawing parameters of cover of water heater are confirmed by repetitious technologic trials traditionally because of complicated surface of the cover top. Higrade simulates and analyzes the blank-holder pressure, draw-bead, blank size of the deep drawing process of the cover of water-heater which they how effect product forming quality using drawing analysis software. With regard to the insufficiency of current process the new improving process is introduced by adopting ring semi-circular draw bead and small size of blank. It can reduce the blank-holder pressure obviously, improve the formability of deep drawing part and product quality, it also can improve the utilized rate of sheet metal blank materials.
