Abstract
An apparatus for deburring foundry cores (3) and similar workpieces, comprising a vibration device, a stationary base (10) which carries the vibration device, and a deburring template (4), is designed and constructed for an effective deburring with a reduced risk of damage to the workpiece, and with less wear on tools such that the vibrating movement of the vibration device occurs exclusively in vertical direction, and that a clearance is absent between the contours of the cores (3) to be deburred and the contours of the deburring template (4), so that the burr is cut off as the core (3) passes through the deburring template (4).
Claims7
An apparatus for removing burrs which protrude from the peripheral edge of a workpiece and comprising
- a template having a rigid internal profile which closely conforms to the entire outline of the peripheral edge of the workpiece, with no significant clearance therebetween,
- means for supporting the workpiece so that the peripheral edge of the workpiece is aligned in a predetermined direction with said internal profile of said template,
- means for vibrating said template so that the template moves exclusively along said predetermined direction, and
- means for guiding said workpiece supporting means for linear movement along said predetermined direction and so that the supported workpiece moves through said internal profile of the template and so that the internal profile acts to sever the protruding burrs from the peripheral edge of the workpiece.
A method for deburring a workpiece such as a molded foundry core comprising the steps of
- providing a workpiece having burrs which protrude from the peripheral edge thereof,
- providing a template having a fixed internal profile which closely conforms to the entire outline of said peripheral edge of the workpiece, with no significant clearance therebetween,
- supporting the workpiece and the template so that the peripheral edge of the workpiece is aligned in a predetermined direction with said internal profile of said template,
- vibrating said template so that the template moves exclusively along said predetermined direction, and
- guiding said workpiece supporting means for linear movement along said predetermined direction and so that the supported workpiece moves through said internal profile of the vibrating template and the internal profile acts to sever the protruding burrs from the peripheral edge of the workpiece.
