Abstract
Matryca składa się z dwóch części (2a, 2b) z kształtowymi powierzchniami odwzorowującymi kształt modelu użytego do wykonania powierzchni kształtowych, pomiędzy którymi mocowany jest profil zamknięty (1). Każdą część (2a, 2b) matrycy, górną i dolną, wykonuje się ze skrzynki ze sztywną podstawą (3), którą to skrzynkę wypełnia się podatnym na odkształcenie materiałem formierskim (4), którego głównym składnikiem jest osnowa z materiału ziarnistego, zwłaszcza z piasku, ulegająca zagęszczeniu i lokalnemu umocnienieniu pod wpływem deformacji plastycznej kształtowanego w matrycy profilu zamkniętego (1). Przeciwległe boki skrzynki są zaopatrzone w wycięcia do zamocowania końców profilu zamkniętego (1). Powierzchnie kształtowe obu części (2a, 2b) wykonuje się z nadmiarem uwzględniającym wymiar stref odkształcenia (5, 6) matrycy pod wpływem deformacji plastycznej kształtowanego profilu zamkniętego (1), poprzez użycie do ich wykonania modelu pomniejszonego o założony wymiar stref odkształcenia (5, 6) względem wymiaru końcowego ukształtowanego profilu zamkniętego (1). Przedmiotem zgłoszenia jest również sposób hydromechanicznego kształtowania profili zamkniętych.The matrix consists of two parts (2a, 2b) with shaped surfaces reflecting the shape of the model used to make shaped surfaces, between which the closed profile is attached (1). Each upper and lower part (2a, 2b) of the matrix is made of a box with a rigid base (3), which box is filled with deformable molding material (4), whose main component is a matrix of granular material, especially sand , subject to compaction and local strengthening under the influence of plastic deformation of the closed profile shaped in the matrix (1). Opposite sides of the box are provided with cutouts to fix the ends of the closed profile (1). The shaped surfaces of both parts (2a, 2b) are made with an excess taking into account the dimension of the deformation zones (5, 6) of the matrix under the influence of the plastic deformation of the shaped closed profile (1), by using a model reduced by the assumed dimension of the deformation zones (5, 6) ) relative to the final dimension of the shaped closed profile (1). The subject of the application is also a method of hydromechanical shaping of closed profiles.
