Machine for the deposition of material for the production of pieces
A machine for the deposition of material for the production of pieces, with a structural housing including an inner chamber in which an arc torch operates in order to melt a strand of material with which pieces are formed on a supporting table; the arc torch is mounted on a frame positioned horizontally in the upper part of the chamber, on which the arc torch is mounted with a movement system driven by several actuation devices located on the outside of the structural housing. The supporting table is positioned below the frame in an assembly that can move towards or away from the frame, with a side sub-chamber located facing the supporting table and equipped with a cover that opens outwards, and towards which the supporting table can pivot for the removal of the pieces.
1. A machine for a deposition of material for production of pieces, comprising a structural housing having an inner chamber and a side sub-chamber,
the inner chamber comprising
a frame positioned horizontally in an upper part of the inner chamber;
a supporting table, positioned below the frame, that moves towards or away from the frame;
an arc torch for melting a strand of material with which the pieces are produced on the supporting table, wherein the arc torch is mounted on the frame positioned horizontally in the upper part of the chamber;
a movement system comprising linear actuators driven by corresponding linear actuation means, the linear actuation means located on an outside of the structural housing,
the side sub-chamber located facing the supporting table and equipped with a moveable cover that opens outwards, and towards which the supporting table can pivot for removal of the pieces produced,
wherein the supporting table has a platform on top, connected to the supporting table by means of a joint on which a gear is mounted that meshes with an actuator gear when the supporting table is in a lowering position of its movement away from the upper part of the inner chamber of the frame, to pivot the platform towards the side sub-chamber.
2. The machine for the deposition of material for the production of pieces, according to claim 1 , wherein the movement system further comprises two perpendicular cross-pieces, each of which is mounted on the frame and movable in two orthogonal directions.
3. The machine for the deposition of material for the production of pieces, according to claim 1 , wherein the arc torch is coupled to each one of the cross-pieces through a support, wherein said arc torch is rotatably installed to the support by means of an actuator.
4. The machine for the deposition of material for the production of pieces, according to claim 1 , wherein the supporting table is installed on a spindle that is driven by an actuator motor located on the outside of the structural housing.
5. The machine for the deposition of material for the production of pieces, according to claim 1 , wherein in the pivoting towards the side sub-chamber, the platform of the supporting table forms a hermetic seal on an interior opening of said side sub-chamber.
