Oscillating table and assembly method thereof

An oscillating table comprising

• a support fixed frame, adapted to be fixed integrally to the ground or to supports fixed to the ground;
• an oscillating structure, insertable into said fixed frame and adapted to accommodate an ingot mold provided with a crystallizer defining a casting direction X;
• at least one actuator adapted to transmit pulses in an alternating direction, upwards and downwards, to the oscillating structure, so as to cause an oscillation motion thereof with respect to the fixed frame;
• elastic means, arranged transversely to the casting direction X and adapted to guide said oscillation motion of the oscillating structure;
• wherein said elastic means comprise two first elastic bars and two second elastic bars, each defining a respective axis, having two respective ends fixed to the fixed frame, and having a respective central portion constrained to the oscillating structure,
• wherein the first elastic bars are arranged parallel to each other, at a first side and at a second side of said fixed frame, respectively, said first side and said second side being parallel to each other and equally spaced apart from said casting direction X,
• wherein the second elastic bars are arranged parallel to each other, respectively at said first side and said second side, below the first elastic bars,
• wherein the first elastic bars are inclined by a first acute angle with respect to a horizontal plane,
• and wherein the second elastic bars are inclined by a second acute angle, different from said first acute angle, with respect to said horizontal plane, whereby two ideal intersection points between the axes of the first elastic bars and the corresponding axes of the underlying second elastic bars define an ideal oscillation axis about which the oscillating structure can oscillate;
• wherein each first elastic bar and each second elastic bar are housed inside a respective hollow housing defining a longitudinal axis parallel to the axis of the respective elastic bar contained therein;
• wherein the two ends of each first elastic bar and each second elastic bar are fixed and pretensioned inside corresponding ends of the respective hollow housing;
• wherein the two ends of each hollow housing are removably fixed to the support fixed frame;
• and wherein a central part of each hollow housing has at least one through-hole, transversal to the longitudinal axis of the hollow housing, at the respective central portion to allow to either constraining or releasing said central portion with respect to the oscillating structure.
