Abstract

The invention relates to the field of machine tools, in particular to the EDM machining of parts of a stamping and press tooling. The purpose of the invention is to improve the accuracy and productivity of processing by simultaneously forming a tooling profile. The wire electrode-tool is cut in the workpiece 7 the desired circuit with the provision of a slope at each point. The cut elements, for example, 2, 5 and 6, are shifted relative to each other before being jammed. The cut width R is determined from the ratio R H-sinot., Where H is the value of the relative shift of the elements, the slope of the cut contour. Then, the obtained electrode on the piercing EDM machine forms all the cavities in the mold matrix at the same time. 5 il. sl 2 3 5 //

Description

one

The invention relates to a machine tool industry, in particular to: 1, an electro-corrosion treatment, and can be used to form parts of a die-press center.

The aim of the invention is to improve the accuracy and performance of the EDM machining of parts of press-die tooling by simultaneously forming a tooling profile.

The method is carried out as follows.

A wire electrode tool 1 is cut out in the workpiece and required (h1 the contour of the electrode element with the provision of a slope at each point) (for example, the element for forming the STRIP and - the covered element 2). with respect to the slope when cutting out the contours of male element 2, encompassing elements 3 and 4 to form protrusions. Inside element 10, element 5 is cut to form a sample in the protrusion, then elements 6 are cut out. The cavities and protrusions are formed from one blank 7. The inclination of the wire electrode tool 1 is performed depending on the casting slope of the cavity in the matrix. Each electrode element is cut out with a predetermined width of the cut R defined by the ratio And is the value of the relative shift of elements, oi is the slope of the cut contour. whether height, t, e.
