Oscillating table for continuous casting

Abstract

The invention relates to an oscillating table for continuous casting, intended for manufacturing longitudinal elements which enables greater precision in the guiding of the mobile structure, reduces maintenance and provides the mobile structure with stability in the oscillation movement thereof. The table comprises a supporting structure (1), a mobile structure (3) defining a first direction (X), at least one actuating element (6) transmitting alternating oscillations in the first direction (X), two pairs of torsion axles (7, 8, 9, 10) which extend in planes transverse to the first direction (X) wherein at least the ends thereof work in torsion and at least four longitudinal joining elements (11, 12), wherein each joining element (11, 12) is joined to at least one end of the pair of axles (9, 10), wherein the joining elements guide the mobile structure (3) in the movement thereof.
