Abstract
Urządzenie do kształtowania kuli drążonej metodą kucia, charakteryzuje się tym, że składa się z matrycy dolnej (1) z wykrojem roboczym, oraz matrycy górnej (2) z wykrojem roboczym, pomiędzy którymi znajdują się elementy podtrzymująco-centrujące (3, 4), które posiadają powierzchnię w kształcie walcowym (3a, 4a), od strony matrycy wykrojów roboczych. Sposób kształtowania kuli drążonej metodą kucia charakteryzuje się tym, że wsad w kształcie rury o średnicy zewnętrznej mniejszej od średnicy (D) kuli drążonej (6) i większej od średnicy (dK) otworów (6a, 6b) oraz o grubości ścianki mniejszej od grubości (gK, gMAX) ścianki (6c) kuli drążonej (6) oraz o wysokości, umieszcza się w wykroju roboczym matrycy dolnej (1) pomiędzy powierzchniami walcowymi (3a, 4a) elementów podtrzymująco-centrujących (3, 4). Następnie matrycę górną (2) wprawia się w ruch postępowy z prędkością v w kierunku matrycy dolnej (1) i odkształca się wsad, przy czym elementy podtrzymująco-centrujące (3, 4) odsuwa się od wsadu w kierunkach (k1, k2) a następnie rozsuwa się matryce (1, 2) oraz wyjmuje się kulę drążoną (6).The device for forming a hollow ball by forging is characterized by the fact that it consists of a lower matrix (1) with a working pattern, and an upper matrix (2) with a working pattern, between which there are supporting-centering elements (3, 4), which they have a cylindrical surface (3a, 4a), from the working pattern matrix side. The method of forming a hollow ball by forging is characterized in that the tube-shaped charge with an outer diameter smaller than the diameter (D) of the hollow ball (6) and larger than the diameter (dK) of the holes (6a, 6b) and with a wall thickness smaller than the thickness ( gK, gMAX) the walls (6c) of a hollow ball (6) and of height are placed in the working pattern of the lower die (1) between the cylindrical surfaces (3a, 4a) of the support and centering elements (3, 4). Then the upper matrix (2) is set in a translational motion at a velocity v towards the lower matrix (1) and the charge is deformed, with the supporting-centering elements (3, 4) moving away from the charge in directions (k1, k2) and then sliding apart dies (1, 2) and remove the hollow ball (6).
