    • Apparatus and method for reducing vibration in a mill stand. The apparatus comprises a roll (4) positioned upstream or downstream of the mill stand (1) and over which the strip material (2) being rolled is passed. The vibration control apparatus comprises an inertia element in the form of a flywheel (7) connected to the roll (4) by a stiffness element in the form of a compliant shaft (6). The components (6) and (7) form a mechanical system which can be tuned in such a way as to introduce a speed fluctuation at the roll (4) which exactly matches the speed fluctuation of the strip material as it enters the roll bite. Both the inertia element (7) and stiffness element (6) can take other forms: for example, the stiffness element could be a flexible drive belt or belts; the inertia element could be a shaft about which the roll (4) rotates, via a stiffness element.

    • A method for making a valve assembly is disclosed. The method includes providing a first work piece having a longitudinal axis and a first end and providing a second work piece having a surface. The method also includes disposing the first work piece and the second work piece axially between a pair of aligned elements that are relatively movable toward and away from each other along the longitudinal axis of the first work piece. Additionally, the method includes relatively moving the pair of aligned elements toward each other to axially clamp the first work piece and the second work piece and actuating the pair of aligned elements and delivering to the first work piece and the second work piece a controlled clamping force that acts to coin a zone of surface contact between the first end and the surface. Further, the method includes repeating the actuating of the pair of elements a plurality of times. An apparatus used to perform the method is also disclosed

    • A process and device for manufacturing cylindrical hollow bodies out of a blank through cold forming using roll cylinders is provided. The axes of the roll cylinders in this process are essentially adjusted parallel to the axis of the workpiece and execute, essentially radial to the workpiece, an oscillating, reciprocating movement. This reciprocating movement is executed in such a manner that in the upper oscillation stop the roll cylinders and the workpiece preferably just barely touch each other without the application of force, and in the lower oscillation stop preferably dip into the surface of the workpiece up to the desired infeed depth in order to achieve the demanded external diameter of the workpiece. With this process the very high static pressures required for press roll machines can be avoided, which results in small and light engine frames, and simultaneously makes it possible to machine workpieces with flanges directly up to the flanges.
    • 提供了一种用于通过使用辊筒冷成型从坯料制造圆柱形中空体的方法和装置。 在这个过程中辊筒的轴线基本上是平行于工件的轴线调节的,并且基本上径向地与工件进行摆动,往复运动。 这种往复运动以这样的方式执行:在上振动停止中,辊筒和工件优选地在不施加力的情况下几乎不会相互接触,并且在下振动停止件中优选地浸入工件的表面直到 所需的进给深度,以达到所需工件的外径。 通过这个过程,可以避免压辊机所需的非常高的静压力,从而导致小而轻的发动机机架,并且同时使得可以将具有凸缘的工件直接加工直到法兰。
