Abstract

A punch press having a high-energy, thermal melting device and an improved slag recovery system. The punch press is a bridge-type machine in which the workhead which carries the ram of the punch press and the melting tool moves along a first axis, and the workpiece is moved along a second orthogonal axis. The slag collection system is static for simplistically, economically, and reliably collecting the slag created by the melting tool, and includes a long, slot-like opening congruent with the path of the melting tool. The slot-like opening is in the top of a stationary plenum provided below the workpiece and extends down to an open bottom where a slag tray is provided to collect the slag. A vacuum source is connected to the plenum to draw gases through the slot-like opening and into the plenum for removal. A spark trap is interposed between the vacuum source and the plenum to prevent sparks from entering the vacuum source and causing a fire or explosion.
