A computer program has been created for selecting the profiling route, calculating the rolls for the manufacture of bent symmetrical and asymmetric profiles of read more virtually any real configurations with the issuance of a complete set of drawings.The algorithm of the program is based on the mathematical model of the strip profiling process, which allows geometric and energy-strength parameters calculation.To create an algorithm for designing roll calibrations to produce curved profiles, a unified description of the shape of the profile was proposed.The left and right halves of the cross section of the profile are treated as separate sets of alternating straight sections and rounds.

The configuration of each of them for one and the other profile half is entered separately, starting from the middle.For each point of conjugation (the beginning and end of the section), the coordinates, the rounding radius and the rotation angle are specified (or calculated in the future).The accepted profile shape description makes it possible to compile a general algorithm for calculating the roll calibrations of virtually any profiles, and not to develop an algorithm for bolia outlet gent each profile or group of profiles.
