Abstract
An upper tool holder apparatus (1) for removably supporting an upper tool (9) on an upper table (3) of a press brake includes: a holder body (5) removably attached to the upper table; an upper tool clamp (11) attached to the holder body, for pushing and fixing an upper portion of the upper tool to a support plate (7) provided at a lower portion of the holder body; a clamping force adjusting device (13) for adjusting a clamping force of the upper tool clamp; and a clamp releasing device (15) for releasing the upper tool clamped by the upper tool clamp. In particular, a wedge-shaped member (17) vertically movably provided at a lower portion of the upper tool clamp is formed with a stop portion (17K) engageable with and disengageable from an engage portion (9K) formed in the upper tool (9). Further, an upper tool (9) for a press brake includes: a contact surface (6F) contactable to a lower surface of a support plate (7) provided at a lower portion of a holder body (5) of an upper tool holder apparatus (1) attached to an upper table (3) of a press brake; a slide surface (9S) slidably contactable to a front or rear surface of the support plate; an engage portion (9K) engageable with and disengageable from a stop portion (17K) of a wedge-shaped member (17) vertically movably provided at an lower portion of an upper tool clamp (11) pivotally attached to the upper tool holer apparatus (1); and a work processing portion (9M) for processing a work in cooperation with a lower tool.
