Abstract

Sposób kształtowania plastycznego półfabrykatu, zwłaszcza do wytwarzania wkrętu medycznego z łbem walcowym polega na tym, że element wsadowy (1) ze stali implantacyjnej w kształcie walca umieszcza się poprzez pierwszy koniec w wykroju (2a) matrycy (2) o kształcie walca przelotowego ograniczonego od drugiego końca popychaczem (3). Następnie do wykroju stempla walcowego nieprzelotowego (4a) wprowadza się drugi koniec elementu wsadowego (1) i dociska się go przy użyciu stempla (4) przez co spęcza się go kształtując łeb walcowy pierwszego półfabrykatu. Kolejno ukształtowany pierwszy półfabrykat w walcowej części nieodkształconej umieszcza się na brzegu szczęki nieruchomej i za pomocą szczęki ruchomej i szczęki nieruchomej, które posiadają rowki o zarysie gwintu pierścieniowego walcuje się pierwszy półfabrykat wprawiając w ruch posuwisty szczękę ruchomą. Przy czym rowki przemieszczającej się szczęki ruchomej oraz rowki szczęki nieruchomej wcinają się w półfabrykat obracają go kształtując drugi półfabrykat z gwintem pierścieniowym.The method of shaping a plastic blank, especially for producing a medical screw with a cylindrical head, consists in placing the insertion element (1) of cylindrical implant steel through the first end in the blank (2a) of the die (2) in the shape of a through-cylinder limited from the second the end with the pusher (3). Next, the second end of the charge element (1) is inserted into the blank of the blind punch (4a) and pressed with the punch (4), which causes it to buckle, shaping the cylindrical head of the first blank. The successively shaped first blank in the cylindrical part is placed on the edge of the fixed jaw, and the first blank is rolled by means of a movable jaw and a fixed jaw, which have ring-thread grooves, causing the moving jaw to slide in a sliding motion. While the grooves of the moving jaw and the grooves of the fixed jaw cut into the blank, they rotate it to form a second blank with an annular thread.
