Abstract
The flame-cut sheet metal elements to be deburred have a surface which lies substantially in a plane and have edge portions which are formed with sharp-edged metallic burrs extending generally in said plane and carry slag beads which protrude from said surface. Tool means are caused to perform a gyratory motion parallel to said plane and while performing said motion are engaged with said slag beads to break them off. Said tool means are caused to engage also said metallic burrs while performing a gyratory motion parallel to said plane, whereby said burrs are impact-deformed.

In a process of deburring flame-cut sheet metal elements having a surface which lies substantially in a plane and having edge portions which are formed with sharp-edged metallic burrs extending generally in said plane and carry slag beads which protrude from said surface, wherein tool means are caused to perform a gyratory motion parallel to said plane and while performing said motion are engaged with said slag beads to break them off,
- the improvement residing in that
- said tool means are caused simultaneously to engage and impact-deform said metallic burrs while performing a gyratory motion parallel to said plane.
In a tool for deburring flame-cut sheet metal elements having a surface which lies substantially in a plane and having edge portions which are formed with sharp-edged metallic burrs extending generally in said plane and carry slag beads which protrude from said surface, in combination
- a plurality of first tool elements arranged in a first circle,
- a plurality of second tool elements arranged in a second circle which is concentric to and smaller in diameter than said first circle,
- drive means for imparting to said first and second tool elements a simultaneously gyratory motion about an axis on which said circles are centered, and
- bearing means engageable with said sheet metal element in a position in which said first and second tool elements are engageable with said slag beads and burrs, respectively, the tool elements being adapted to break off said slag beads and to impact-deform said burrs in the gyratory motion of said first and second tool elements about said axis.
