摘要： A seamless tube-like blank is formed and cut into single annular parts which consecutively are profiled by means of two tools having the shape of solids of rotation. During the profiling operation, the specific surface pressure on the inside and on the outside of the workpiece is equal. Preferably, an inner profiling roller and an outer annular profiling tool is used, the mutual distance thereof being variable. Simultaneously, the inner roller acts on the workpiece with its convex outer surface, and the outer annular tool acts on the workpiece with its concave inner surface. Thus, the effective surface pressures on the inside and on the outside of the workpiece are equal during processing thereof. The apparatus is equally well suited for the manufacturing of steel rims and aluminium rims.

摘要： This device is especially suited for gripping heavy and cumbersome pieces of sheet metal without human force and transporting them from a stacking device to a bending press for further processing. By means of rotatable clamping of gripping jaws mounted on a vertically movable jaw carriage, a laterally movable first horizontal carriage, a longitudinally movable second horizontal carriage and a swivel or turning device, any piece of sheet metal can be directly rotated or turned about a horizontal gripping jaw axis or can be rotated in the plane of the sheet and then regripped, or can be subjected to both actions. The piece of sheet metal normally held by two pairs of jaws is further supported below the jaw axis by multi-component sheet metal support devices carried on two independently movable sheet metal support carriages. This makes it possible to position each edge of the metal sheet or panel in the operating region of a suitable tool, such as a bending die for upward and downward bending operations and to hold the sheet metal sheet in position during the working operation.

摘要： A calibrating unit for pipe sections is provided with calibrating jaw means and brake means, the jaw means measuring the inside and outside diameter of the pipe which is used in combination with feed rolls and tilting tables which move the pipe sections into the calibrating unit. The feed rolls are synchronized with the brake means and are swivelably connected in the vertical plane onto the tilting tables with the calibrating jaw means located on both sides of the horizontal plane of said tables through which the pipe sections are moved by the feed rolls and in which horizontal plane these pipe sections are aligned by said calibrating jaw means.
