摘要

Automatic bi-directional sawing machine, characterized essentially by the fact that for wooden boards to be fractionable according to quadrangular rectangular pieces of pre-established dimensions, said machine has a general bench in which, on the one hand, there is a mobile platform sustainer of the board to fractionate, performing the displacement of this, on appropriate guides, by means of a lower motor with gear transmission of wheel and rack, during such movement being carried out the initial double cutting of the wood by two parallel sawing discs, arranged on the silver fixed to the bedplate, and provided with individual drive motor, while the subsequent perpendicular sawing of the dashboard is verified, once the first two sides have been cut and the stroke limit reached by the platform, by means of a tandem integrated by other two parallel saw discs equally and arranged on the mobile platform, with its corresponding individual motor, whose tandem is arranged and runs, for this purpose, on two guides perpendicular to the trajectory of the platform for the realization of the appropriate 90º cuts that complete the aforementioned rectangular shape of the board, and with the particularity that the displacements of the tandem are carried out, in turn, by means of an electric motor that acts directly on a transverse bar provided with two pulleys, which, in turn, give movement to two respective cables without end of traction of the tandem, cables that are supported horizontally by means of two other free-turn pulleys established in the other two ends of the mentioned guides, conveniently joining the two ends of each cable with the corresponding sliding shoe of the tandem, to the effects of providing the subsequent advance and uniform retraction thereof on the guides of the bed.
