FIELD: technological processes. ^ SUBSTANCE: invention relates to technological equipment to process sheet metal and may be used in machine building, instrument making and other industries for finishing cut of parts. Device comprises fixed matrix, upper puncheon matrix, movable hold-down, upper puncheon, lower puncheon matrix and lower puncheon and units of relative displacement. Units of relative displacement are arranged in the form of upper and lower cams. Cams have double profile and are installed with the possibility of synchronous rotation. They interact with upper puncheon matrix, upper puncheon, lower puncheon matrix and lower puncheon. Puncheons are moved to fix diversion, to further carry out primary deformation of stock, for reversible deformation of stock and final cut of orifice. ^ EFFECT: invention provides for reduced size of rough edge in cutting of parts from sheet material. ^ 6 dwg |
