<p>The present invention provides a tool centering mechanism for a punch press having a plurality of tools installed in juxtaposition and which can simultaneously be replaced with new ones, wherein the tool pitch of the tools can be adjusted to agree with the pitch of corresponding tools. A tool holder 32 is provided on a first support 7, the tool holder 32 has a plurality of tool support sections 13, 14 spaced at a predetermined pitch and which can each support a tool 9. The tool support sections 13, 14 each allow a tool 10 corresponding to the tool 9 and cooperating with the tool 9 in punching to be installed on its axis. In a punch press of the above construction, the tool holder 32 and one 10B of the corresponding tools can be moved relative to the first support 7 and a second support 8, respectively. Simulated punching is carried out to move the tool holder 32 and the adjustable corresponding tool 10B so that the corresponding tool 10B can be installed on the axis of a corresponding one of the tools 9 on the first support 7. <IMAGE></p> |
