Abstract

Tool coupling device (1), particularly for press machines, of the type comprising: at least one magnet (2) arranged next to a tool-holder housing (3) of the machine and operatively active on a ferromagnetic abutment surface of a tool, in order to keep it inside said housing (3); locking means (4) operatively active on the tool, to prevent its accidental disengagement from the housing (3). The locking means (4) originally comprise at least one jaw (5) secured next to the tool-holder housing (3) through an hinge (6) and having a portion (5a) that is operatively active on the tool; resilient means (7) connected to the jaw (5) on the opposite part to the active portion (5a) with respect to the hinge (6), to rotate the jaw (5) and press said active portion (5a) against the tool; means (8) to adjust a pre-loading of the resilient means (7). <IMAGE>
