LARGE-SIZED MATRIX IN THE FORM OF A JOINED SHELL, FOR EXAMPLE, FOR PACKING AND CURING OF POLYMERIC COMPOSITE MATERIALS WITH AUTOMATED FORMATION OF WORKING SURFACE Russian patent published in 2006 - IPC B29C41/20 B29C33/42 B29L31/30 B29K105/06 

FIELD: production equipment for packing and curing of polymeric composite materials of large-sized contour-forming parts of flight vehicles and shells of working surfaces of volumetric machining attachments of the shell type, applicable in the aerospace industry.

SUBSTANCE: the large-sized matrix in the form of a joined shell for packing and curing of polymeric composite materials with automated formation of the working surface has a shell with a working surface corresponding to the formed part, and movable sections with rows of supports with thrust bearings moving in their axis and a numerical programmed control system. The shell is made of replaceable lining cells with fragments of the working surface of the part on one side, and the location surfaces - on the other side for well-defined installation on four adjacent supports. The end edges of the lining cells are made with chamfers forming a cavity between the adjacent cells filled with wedge-shaped calibrated inserts. The movable sections are made in the form of a bent beam with journals entering the seats of the fixed members for turning the sections through preset angle α_i according to the program and with the rows of supports positioned uniformly at angles β in radii in the system of cylindrical co-ordinates so that the plane planforms of the support thrust bearings in the initial position are on radius R_c(i). Each support is, for example, of the pneumohydraulic type with a linearly-measuring transducer combined with a controller of the system with numeri8cal programmed control.

EFFECT: reduced terms of preparation of production at manufacture of flight vehicles of any class and series.
