Abstract

The invention relates to a method of punching one or more holes in a two-wall workpiece having mutually facing walls where one or more holes is/are to be punched in at least one wall. According to the method, there is inserted in the space between the walls a punch die that has a thickness corresponding essentially to the distance between the walls. The die includes one or more punch cavities. A punch tool having one or more punches is activated on the ouside of the wall subsequent to having moved the punch die to a position in which a punch cavity is located opposite its respective punch. The invention also relates to a punch die (8) for use when carrying out the method. The punch die (8) includes one or more punch cavities (7) and is adapted for insertion into the space between the wall (2, 3) of the two-wall workpiece (1).
