Abstract
A cutter tool cleaning assembly comprises a pair of peripherally opposed wire brush wheels mounted on a metal cutting broach machine so that the machine cutter bar engages and passes between the wheels to cause rolling contact of the wheels with the cutter bar to dislodge metal chips.
Claims11
An automatically self-adjusting metal cutter tool chip removal assembly comprising in combination,
- (a) a dual opposed wire brush wheel assembly,
- (b) a support structure for mounting said dual opposed wire brush wheels in said chip removal assembly in spaced apart opposed peripheral coplanar relationship for bi-directional free rotation and for movement towards and away from each other to change said spaced apart peripheral relationship,
- (c) biasing means biasing said wheels towards each other, and
- (d) a mounting assembly attached to said support structure for mounting said support structure adjacent a linearly moving metal cutter tool for said tool to pass between and engage said wire brush wheels for rolling contact of said brushes on said passing tool to remove metal chips from said tool, each of said dual opposed wire brush wheels having an axis of rotation substantially perpendicular to a direction of movement of said linearly moving cutter tool.
In a broaching metal cutting machine having an elongated cutter bar with a row of metal cutter projections thereon and adapted for reciprocating motion adjacent a workpiece for metal removal therefrom, a chip removal assembly for said machine comprising in combination,
- (a) a support adapted for attachment to said machine,
- (b) a pair of arm members pivotally attached to said support to project therefrom in spaced parallel relationship,
- (c) a pair of wire brush wheels mounted on said arms in opposed spaced apart peripheral relationship to define a space therebetween in which said cutter bar may axially pass, each of said pair of wire brush wheels having an axis of rotation substantially perpendicular to the reciprocating motion of the cutter bar, and
- (d) spring means biasing said opposed wheels into opposite engagement with said cutter bar so that the axial passing of said cutter bar engages said wheels for rolling contact of said wheels on said cutter for chip removal.
In a broaching metal cutting machine having an elongated cutter bar with a row of metal cutter projections thereon and adapted for reciprocating motion adjacent a workpiece for metal removal therefrom, a chip removal assembly for said machine comprising in combination,
- (a) a support adapted for attachment to said machine,
- (b) a pair of arm members pivotally attached to said support to project therefrom in spaced parallel relationship,
- (c) a pair of wire brush wheels mounted on said arms in opposed spaced apart peripheral relationship to define a space therebetween in which said cutter bar may axially pass, said wheels being offset relative to each other along said cutter bar, and
- (d) spring means biasing said opposed wheels into opposite engagement with said cutter bar so that the axial passing of said cutter bar engages said wheels for rolling contact of said wheels on said cutter for chip removal.
