Abstract: Oscillating table in which the oscillation drive, comprising a hydraulic actuator, transmits the oscillating motion to the mould via a spring subject to bending stress, for example a fitted rod. The body of the hydraulic actuator is also anchored to the floor by means of a fitted spring subjected to bending stress. Thus thanks to the absence of any mechanical bearings in the drive mechanism, all disadvantageous movements caused as a result of bearing play, which increases at high oscillation frequencies, are eliminated. Moreover, the use of mould guide elements having a much simpler design and consisting of straightforward bars, also ensures greater guidance precision and enables a reduction in the oscillation marks on the cast product, a reduction that is even more noticeable when working at higher oscillation frequencies. Advantageously, the presence of an anti-roll device, consisting of two or more pairs of bars, for example two pairs, ensures good torsional rigidity of the table.

Abstract translation: 摆动台，其中包括液压致动器的振荡驱动器通过经受弯曲应力的弹簧（例如安装的杆）将摆动运动传递到模具。 液压致动器的主体还通过受到弯曲应力的配合弹簧锚固到地板上。 因此，由于在驱动机构中没有任何机械轴承，所以消除了在高振荡频率下增加的轴承间隙引起的所有不利运动。 此外，使用具有简单设计并由直接杆组成的模具引导元件也确保了更大的引导精度并且能够减少铸造产品上的振动标记，当在较高振荡频率下工作时，降低甚至更显着 。 有利的是，由两个或更多对成对的杆例如两对构成的抗卷装置的存在确保了工作台的良好的扭转刚度。
