The utility model refers to the portal machine for cutting of metal parts, which are used in the field of mechanical engineering, in particular in the construction and manufacture of machines for gas and plasma cutting of details of metal sheets with large dimensions. The portal machine consists of a bridge structure on the portal top on which are mounted mobile support with attached to it, and the transverse and the burner the longitudinal beams of the portal structure are connected through slots and rollers and are implemented in a way allowing motion with one degree of freedom, respectively, in the direction of the axis Y. On one straight path (3) is located on the longitudinal sideways (5), which through the carriage (7) and is situated between the top surface and bottom of the vertical beam (9) on the portal structure, on which is mounted a stationary plate (13) with shaped lower part side air chambers (16), as the central in the plate (13) is a fixed element (17) for submission of air to the cameras (16). |
