Hatebur has introduced new SAM technology (servo-hydraulic ejector module) on its HM 35. The modules, which can be installed at each forming station and individually controlled and adjusted via touch screen. The ejection process of the forging from the die takes place in two phases, the loosening and the pushing out of the part. The ejector module has an integrated pressure and position measuring system with which the movement and the ejector force can be exactly determined. An integrated braking function prevents parts from falling down and improves process security. One of the new functions of the module is the combination of descaling and in-die forming. Another highlight is the slim slug process. Due to the forming of the slug thickness in an intermediate position between the ejector and the punch, a reduced slug thickness is achieved. The SAM drives also allow for piercing and separating the rings.
