Abstract

Matryca dwuczesciowa do wyciskania wyrobów z rowkami srubowymi, zwlaszcza wiertel kretych oraz nawiertaków i rozwiertaków charakteryzuje sie tym, ze sklada sie z dwóch jednakowych segmentów (1) i (2), które po zlozeniu tworza stozkowy otwór (4) o srednicy (D) odpowiadajacej srednicy ksztaltowanego wiertla oraz srednicy (d) odpowiadajacej srednicy grzbietu wiertla, zas na stozkowej powierzchni otworu (4) segmenty (1) i (2) posiadaja wystepy (3) ksztaltujace rowki wiórowe wiertla pochylone wzgledem osi segmentów (1) i (2) o kat (?) odpowiadajacy katowi pochylenia linii srubowej wiertla, wystepy (3) ksztaltujace rowki wiórowe wiertla posiadaja w plaszczyznie podstawy (A-A) zarys poprzeczny odpowiadajacy zarysowi poprzecznemu rowka wiórowego wiertla, przy czym zarys poprzeczny wystepów (3) ksztaltujacych rowki wiórowe wiertla od plaszczyzny podstawy (A-A) do plaszczyzny przekroju (B-B) zmniejsza swoja wysokosc zachowujac ksztalt zarysu poprzecznego, którego wymiary zmniejszaja sie proporcjonalnie w stosunku do zarysu poprzecznego wystepów (3) ksztaltujacych rowki wiórowe wiertla w plaszczyznie podstawy (A-A) w ten sposób, ze w punkcie (5) przechodzi w powierzchnie (6) walcowa, ponadto segmenty (1) i (2) posiadaja dodatkowo wykroje (7) przebiegajace wzdluz linii przeciecia wystepów (3) ksztaltujacych rowki wiórowe wiertla i powierzchni stozkowej otworu (4).The two-part die for extruding products with helical grooves, especially boring drills as well as countersinks and reamers, is characterized by the fact that it consists of two identical segments (1) and (2), which when folded form a conical hole (4) with a diameter (D) corresponding to the diameter of the shaped drill and the diameter (d) corresponding to the diameter of the back of the drill, and on the conical surface of the hole (4) the segments (1) and (2) have projections (3) shaping the chip grooves of the drill inclined relative to the axis of the segments (1) and (2) by angle (?) corresponding to the angle of inclination of the drill bolt line, the projections (3) shaping the drill chip grooves have in the base plane (AA) a lateral profile corresponding to the cross profile of the drill chip groove, while the transverse outline of the protrusions (3) shaping the drill grooves from the base plane (AA) to the plane section (BB) reduces its height while maintaining the shape of the transverse profile, the dimensions of which reduce in proportion to the transverse contour of the protrusions (3) shaping the chip grooves of the drill in the base plane (AA) in such a way that at (5) it changes into the cylindrical surface (6), in addition the segments (1) and (2) have in addition, blanks (7) running along the intersection line of the projections (3) shaping the chip flutes of the drill and the conical surface of the hole (4).
