Definitions

  • the invention intends to create a machine capable of producing consistent products in shaped sheet metal profiles in various lengths and thicknesses, of different materials, in different sizes, and in mixed shapes such as straight, curved and counter-curves, arcs, parabolas, in angles from zero to one hundred thirty-five degrees, with edges and counter-edges, edges folded back in hemming, spirals both on the outside edges and inside along the strip, and in progressive sequential steps without replacing and manual adjusting the tools.
  • the multifunction combined pressing-bending-calender machine in this invention is equipped with a calendering device with four independent rollers, controlled both in their positions and the rotation speed, along with the possibility of controlling the speed of the positioning callipers, it can also perform closed ring curvatures (tubes) .
  • the cycle to perform a closed tube begins with the execution of a fold along the outer edge as previously described, performed by the upper flap more precisely towards the bottom, in such a way to present the fold to the opposite of the centre.
  • a first arc of curvature is executed with the inner rollers in calendering position (Fig. 38, v2, v3) and with the lower outer roller in bending position and rotated at the desired angle (Fig. No.

Abstract

L'objet de la présente invention est une machine de calandrage et cintrage à la presse combinée multifonctions avec un ou deux volets, pliant et cintrant des tôles avec trois ou quatre rouleaux asymétriques qui déterminent la courbure de l'arc sont positionnés le long du bord externe et/ou sur les volets pour traiter des séquences mixtes telles que des courbes, courbes en v, des spirales ouvertes et/ou fermées, des ellipses, des paraboles, des plis et des contre-plis dans un cycle automatique pour créer des formes géométriques fermées dans la direction longitudinale, plus précisément qui sont circulaires, ovales, rectangulaires, carrées, triangulaires, polygonales, coniques, trapézoïdales, etc., et équipée de pinces de préhension qui tiennent la tôle serrée à usiner, afin de maintenir la position dans toutes les phases, le tout dans une structure unique. La machine en question est gérée par une commande numérique continue (CNC), un système ouvert qui est programmable en réglant les cycles de mouvement des actionneurs en fonction des processus à exécuter. Elle est également équipée d'un dispositif de découpe et de profilage avec des outils circulaires rotatifs pour couper et plier les deux bords longitudinaux afin d'obtenir des produits complets et finis, tels que des conduits, des tuyaux de descente, des gouttières, des bandes de recouvrement, des tuyaux, divers revêtements divers, etc. de façon à satisfaire aux besoins de production, principalement dans les secteurs civil, industriel, commercial et agricole.
