Set die holder / tray with anti-rotation means for punching forming machine.

摘要

Set of die holder (10, 11, 12) and tray (40) for forming hot stamping press materials such as steel and the like, said die holder a rear side (12b) closed which extends along the direction (YY) cross and an open parallel to said back side front side, comprising a first means (20, 43; 220, 43; 320, 43; 420, 43) for relative positioning and locking of the tray (40) with respect to the die holder (10, 11, 12), second means (30, 42; 230, 42; 330, 42; 430, 42) to limit relative rotation / rotary translation of the tray (40) relative to the die holder around an axis parallel to the vertical direction (ZZ), said second anti-rotation means an element (30, 31; 230, 231; 330, 331; 430, 431) comprising female integrated into the die holder (10) and an element (42) which thien integrated male tray (40), said female a seat (; 231;; 331 431 31) element being provided and at least one open in correspondence with the front side of the die holder and consisting said male a protrusion (42) element integrated with the tray (40) and extending outwardly along the vertical axis (ZZ) from the surface side (41a) lower base (41) of said tray, for mating the element (30, 31; 230, 231; 330, 331; 430, 431) female through a linear displacement along the longitudinal direction (XX) from the front side open to the rear side (12b) closed and vice versa, and said first locking means comprises an element (20; 220b ) male partially projecting from the plane (12a) of the die holder (12) along the vertical direction (ZZ) from a first seat (13) disposed proximate side (12b) back closed end of said die holder (12 ) and capable of preventing a rotation of the tray (40) about an axis orthogonal to said plane (12a) of the die holder (12).
