    Abstract: 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.

    Abstract: An easy manufacturing method of a slip stopper, and apparatus therefor, that has a great slip stopping effect and can be used for a location where a problem occurs if a though hole is opened therein. After a protruding portion is formed on a steel plate, by using a first punching die unit, so as to protrude from the upper surface in a plate thickness direction, a concave portion and drain channels are formed in the protruding portion by shear planes that extend substantially perpendicular to the steel plate upper surface and have been half-blanked so as not to open a through hole in the steel plate by using a second punching die unit.
