摘要： In an upper tool for a press brake formed with an inclined surface (9S) narrowed upwardly at an upper portion thereof and an engage groove (9G) formed under the inclined surface (9S). The inclined surface (9S) is brought into contact with an inclined surface of an upper tool clamp member (11), when the upper tool is clamped between an upper tool holder body (5) and an upper tool clamp member (11), in such a way that clamping force can be further increased when the upper tool is engaged with a die (63). Further, in an upper tool holder apparatus for a press brake, the pivotal upper tool clamp member (211) is formed with an engage projection (211P) for engaging a drop prevention groove (205G) formed in the upper tool (205). The upper tool holder apparatus further comprises a clamp operation lever (215) which can be selectively moved to a clamp position "A" at which the clamping force can be applied to the upper tool clamp member (211) from a clamping force generating spring (213) to clamp the upper tool tightly; an unclamp position "B" at which the clamping force can be reduced to allow the upper tool to be adjustably shifted horizontally, and an exchange position "C" at which the upper tool clamp member (211) can be moved way from the upper tool to allow the upper tool to be exchanged vertically with another one.

摘要： An upper die holder apparatus having a holder body has an upper die clamp supported to the holder body with a supporting point supporting the upper die clamp in a vicinity of a center in a vertical direction of the holder body. A clamping force applier is provided to the holder body for pressing an upper portion of the upper die clamp so that the upper die clamp clamps the upper die. A pressure receiver is provided to an upper portion of the upper die clamp. The pressure receiver, having a pressure sensing surface, is provided so that its advancing and retreating are adjusted to a pressing direction by the clamping force applier and the pressure receiver is provided so that an opening amount of the upper die clamp at the time of unclamping is freely selected between a plurality of stages.

摘要： In an upper tool for a press brake clamped between a support plate (7) of an upper tool holder body (5) attached to a lower portion of an upper table (3) and an upper tool clamp member (11), the upper tool (9) is formed with an inclined surface (9S) narrowed upward at an upper portion thereof and with an engage groove (9G) engaged with an engage projection (11K) of the upper tool clamp member (11) and formed under the inclined surface (9S). Therefore, the inclined surface (9S) is brought into contact with an inclined surface of the upper tool clamp member (11), when the upper tool is clamped between the upper tool holder body (5) and the upper tool clamp member (11), in such a way that clamping force can be-further increased when the upper tool is engaged with a die (63). Further, in an upper tool holder apparatus for a press brake, the pivotal upper tool clamp member (211) is formed with an engage projection (211P) engaged with a drop prevention groove (205G) formed in the upper tool (205), and the upper tool holder apparatus further comprises clamp operation lever (215) for selectively moved to a clamp position A at which the clamping force can be applied to the upper tool clamp member (211) from the clamping force generating spring (213) to clamp the upper tool tightly; an unclamp position B at which the clamping force can be reduced to allow the upper tool to be adjustably shifted horizontally, and an exchange position C at which the upper tool clamp member (211) can be moved way from the upper tool to allow the upper tool to be exchanged vertically with another one.
