Upper tool holder apparatus for press brake

摘要

An upper tool clamp is provided that is supported by a holder body arranged on an upper table of a press brake, so that the upper tool clamp can be oscillated between a clamped state and an unclamped state. A pressing member is mounted on a lower portion of the upper tool clamp in order to press an upper tool on an upper tool support portion which is mounted on a lower portion of the holder body. Further, an engage projection is formed on the upper tool clamp and freely engageable with a drop prevention groove which is formed on the upper tool. In addition, a first clamp/unclamp device and a second clamp/unclamp device are mounted on the holder body, respectively.
