Abstract
A knife support is part of the apparatus, and with a knife it passes by at the edge of the work piece which is to be deburred. The edge of the knife corresponds in its length at least to the length of the edge to be deburred. In order to be able to shear both the front end and the rear end of slabs with one and the same construction in a simple and sturdy way, the knife support is provided as a rocker arm which can be moved with a pivot drive. The swivel axis of the rocker arm can be directed about parallel to the edge of the work piece to be deburred.
Claims21
An apparatus for the deburring of work pieces comprising
- a frame;
- means to support a work piece;
- a swivel drive disposed on the frame;
- a support lever pivoted at one end on the frame and providing a swivel axis located intermediate between the two ends of the support lever;
- means for moving the support lever engaging the support lever at the other end of the support lever;
- a rocker arm rotatable around said swivel axis and movable by the swivel drive;
- a knife having an edge and mounted at the rocker arm where the length of the knife edge corresponds at least to the length of an edge of the work piece to be deburred, where the rocker arm can be moved past the edge of the work piece to be deburred, where the position of the knife edge versus the edge to be deburred is adjusted by changing the location of the swivel axis of the rocker arm by moving the support lever, and where the swivel axis of the rocker arm is directed about parallel to the edge to be deburred.
A method for the deburring of work pieces comprising
- supporting a work piece on a frame with a swivel drive disposed on the frame;
- rotating a rocker arm rotatable around a swivel axis and movable by a swivel drive, where the rocker arm can be moved past the edge of the work piece to be deburred;
- adjusting the position of a support lever pivoted at one end on the frame, where the support lever supports a swivel axis of the rocker arm disposed intermediate to the ends of the support lever and the support lever is moved with means for moving the support lever engaged at the other end of the support lever;
- engaging the edge of a work piece to be deburred with a knife having an edge and mounted at the rocker arm where the length of the knife edge corresponds at least to the length of an edge of the work piece to be deburred, and where the swivel axis of the rocker arm is directed approximately parallel to the edge to be deburred.
