SU1518057A1 - Die for manufacturing articles of angle type with a hole in one flange - Google Patents

Abstract

The invention relates to the processing of metals by pressure, namely to sheet metal stamping and can be used, for example, in the manufacture of parts for special roller chains. The purpose of the invention is to improve the quality of products. The stamp contains a bending matrix installed on the cup springs on the top plate, and a bending punch, the edge of which is placed along the feed direction, as well as a hole punching unit on the shelf of the bent workpiece. A guide unit is placed between the bending tool and the punching unit, which allows the curved workpiece to rotate around the cylindrical support along the block groove of the shoe. In this case, the shelf on which the hole is punched is installed in a plane parallel to the mirror of the piercing matrix. The transfer of the blanks is carried out by a gate, fixed in the knot by punching-stops. The device provides for obtaining products of high accuracy, since Punching is done after calibrating the bent workpiece. 5 il.
