Device for edge trimming of sheet metal plates

摘要

The device has a lower holder and an edge trimming matrix between the facing surfaces of which the plate can be clamped, with its section to be trimmed off extending over the edge of the lower holder and the matrix. A trimming stamp is guided along the outside of the lower holder. The outer-side (11) of the matrix (3) is set back in relation to the outside of the lower holder by the thickness of the plate. The matrix has a displacement convolution (14) which with a flank (15) of its cross-section connects directly to the edge (16) of the matrix.
