Abstract
A vertical internal broaching machine includes a workpiece holder mounted on a machining table of the broaching machine. A vertically displaceable broaching slide is mounted beneath the machining table which slide draws a broach through a workpiece at the workpiece holder. A vertically displaceable broach feed slide is mounted above the workpiece holder, and an inclined feed channel for the workpieces terminates in front of and above the workpiece holder. A mask extends up to one end of the feed channel and is swivelable from the plane of the feed channel to the workpiece holder by means of a swiveling drive means. An ejection chute extends from the mask. A separating means is mounted above the feed channel for releasing workpieces to the mask when the mask is in the raised position. A stop mounted on the broaching slide associated with the workpiece holder projects between the mask and the ejection chute when the broaching slide is in the raised position and releases the mask when the broaching slide is in the lowered position.
