Abstract
(EN)
The invention relates to a device for cutting volumes of expanded polystyrene foam or similar, producing double-curvature surfaces, comprising a first pair of linear guides, on each of which linear guides slide two pairs of plates disposed on sliders, wherein each pair of plates is connected by a horizontal beam. The two pairs of plates and the pair of horizontal beams allow a block of expanded polystyrene foam material or similar to be supported and secured for cutting. The material block, supported on the plates, is moved by a first pair of synchronised belts and pulleys, which are actuated by a first pair of stepper motors, which are activated simultaneously, wherein, when moving, the material block faces a rectangular frame that is disposed perpendicular to the trajectory of the movement of the block, said rectangular frame having a fixed position and being provided with a flexible sheet covered by a thermally and electrically insulating cover, on which a resistive thermal wire is wound in a helix, by means of which an electric current is circulated which heats the resistive thermal wire and vaporises the area before making physical contact with the material block during the movement thereof.

Aparato para cortar volúmenes de espuma de poliestireno expandido o similar obteniendo superficies de doble curvatura, que comprende un primer par de guías lineales, sobre cada una de las guías lineales se desplazan dos pares de placas dispuestas sobre patines, donde cada par de placas se conectan por una viga horizontal; los dos pares de placas y el par de vigas horizontales, permiten sostener y fijar un bloque de material de espuma de poliestireno expandido o similar para el corte; el bloque de material apoyado sobre las placas, es desplazado por un primer par de correas y poleas sincrónicas, que son accionadas por un primer par de motores paso a paso, que se activan simultáneamente; donde el bloque de material en su desplazamiento, enfrenta un marco rectangular que está dispuesto perpendicularmente a la trayectoria del desplazamiento del bloque, dicho marco rectangular tiene una posición fija y dispone de una hoja flexible la cual está recubierta de una funda de aislación térmica y eléctrica, sobre la cual se enrolla en hélice un alambre térmico resistivo, por el cual se hace circular una corriente eléctrica que calienta el alambre térmico resistivo y vaporiza la zona previa al contacto físico con el bloque de material durante el desplazamiento de éste.

Appareil pour découper des volumes de mousse de polystyrène expansé ou analogues de manière à obtenir des surfaces à double courbure, comprenant une première paire de rails linéaires sur chacun desquels se déplacent deux paires de plaques disposées sur des patins, chaque paire de plaques étant reliée par une poutre horizontale, les deux paires de plaques et la paire de poutres horizontales permettant de soutenir et de fixer un bloc de matériau de mousse de polystyrène expansé ou analogue pour le découper. Le bloc de matériau en appui sur les plaques est déplacé par une première paire de courroies et de poulies synchrones, actionnées par une première paire de moteurs pas à pas activés simultanément. Pendant son déplacement, le bloc de matériau fait face à un cadre rectangulaire disposé perpendiculairement à la trajectoire de déplacement du bloc, ledit cadre rectangulaire ayant une position fixe et disposant d'une lame flexible recouverte d'une enveloppe thermiquement et électriquement isolante, sur laquelle est enroulé hélicoïdalement un fil thermorésistif dans lequel circule un courant électrique chauffant le fil thermorésistif et vaporisant une zone avant son contact physique avec le bloc de matériau pendant le déplacement de ce dernier.
