Abstract

The invention relates to electrophysical methods of forming. The purpose of the invention is to improve the accuracy of manufacturing the backlight-free parts of metal inserts and metal plates with an insert hole, as well as non-metallic inserts and non-metallic plates. The goal is achieved due to the fact that the mating elements are made using wire tools on a photocopier machine. The tool is moved around the contour using photocopying and simultaneously cutting out the intermediate template of the male part with dimensions less than specified by the diameter of the tool and the intermediate template of the female part with sizes larger than specified by the diameter of the tool, and using the same diameter for cutting the matched parts. 9 il. i cl

Description

The invention relates to electrophysicochemical methods of shaping, namely, the manufacture of matching parts on cutting machines with a photocopier control system,

The aim of the invention is to improve the manufacturing accuracy of backlash-matched parts.

FIG. 1 shows the arrangement of the elements of the installation for the implementation of the proposed method 2 is a section A-A in FIG. one; in fig. 3 - pre-made photocopier, in shape and size that coincides with the contour of matching parts; in fig. 4- intermediate elements; in fig. 5 - covered intermediate element; in fig. 6 - covering part; in fig. 7 - covering the intermediate element; on fi1. 8 - covered matching part; in fig. 9 - backlash-free connection of mating parts.

The installation for implementing the proposed method contains the original photocopier 1, the object table 2 of the photocopier, the clip 3 of the EDM cut-out machine, the photo-head 4, the wire tool 5, the table 6 of the machine, the workpiece 7, the photodiode 8, encompass ( covered intermediate element 10, covering the cusp when cutting intermediate elements,

Recurrent part 11, covered mating part 12, optical axis 13 of photocopier system.

The method is carried out as follows.

The product is made, which is a backlash-free Matching covered and covering cross-shaped parts. The material of the mating part is made of nickel silver, 2 mm thick, the material of the female part of the mating part is brass, 2 mm thick. The dimensions of the mating part being covered are 15x15 mm, the beam width is 3 mm.

A photocopier of a cruciform shape of a predetermined size (Fig. 3) is prefabricated. The initial photocopier is fixed on a subject table 2 of a photocopier mounted on the bracket 3 of an electroerosive cutting machine. Photo head 4 is located on the frame. On the clip rewind. Wire tool

The tool is driven to a depth of 1 mm.

 After that, the glass plate is displaced to align the center of the photo40 of the diode 8 with the light-shade boundary of the mating mating element 10 and the hole in the mating mating part 11 is cut. The opening in the mating mating part 11 is half the size of the mating intermediate element tool diameter, i.e. coincide with the dimensions of the contour on the photocopier 1.

The diameter of the wire tool and the processing mode of nickel silver are chosen according to the technological recommendations so that the barriers of the covered matching parts are smaller than the opening dimensions of the surrounding intermediate element 9 by half the diameter of the tool used to cut the intermediate elements. After

5, a brass workpiece 7 with a thickness of 1 mm is fastened on the table 6 of the machine, from which the male and female intermediate elements are obtained, and the tool penetrates to a depth of 3-4 mm.

After that, the photocopier 1 is displaced relative to the photohead 4 until the optical axis 13 is aligned with the light-shadow border of the cruciform contour on the photocopier e 1, is fixed in this position, and the enveloping and circumscribed

elements 9 and 10. The alignment of the optical axis 13 is controlled by the position of the center of the photodiode 8, the diameter of which should be located along the border of the light shadow contour on the photocopier 1. The dimensions of the covered intermediate element are smaller than the dimensions of the original photocopier half the diameter of the wire tool, and the dimensions of the surrounding intermediate element

half the diameter more. The spacing element to be covered is glued onto a 1 mm thick glass plate and 2 photocopiers are placed on the object table.

devices.

On the table 6 a brass plate is fixed in which a hole is made in advance for the insertion of a wire tool of the same diameter as

with

The tool is driven to a depth of 1 mm.

 After that, the glass plate is displaced to align the center of the photo0 diode 8 with the light-shade boundary of the mating mating element 10 and the hole in the mating mating part 11 is cut. The hole dimensions in the mating mating part 11 are half the size of the mating intermediate element tool diameter, i.e. coincide with the dimensions of the contour on the photocopier 1.

The diameter of the wire tool and the treatment of nickel silver are chosen in accordance with the technological recommendations so that the dimensions of the male matching part are smaller than the opening of the surrounding intermediate element 9 by half the diameter of the tool used to cut the intermediate elements. After

this male matching part 12 snaps into the hole of the female matching part 11.

Using the proposed method, parts of gem-and-semiprecious stones are machined and gaplessly matched, machined for cutting by a diamond wire tool with CNC, and the fabrication of intermediate elements and matching parts is carried out by the same tool. Formula inventions

The method of processing the mating parts and the mating parts is produced on photocopier cut-outs with the same tool.

machines, in which pre-wire tools cut out intermediate elements-templates, characterized in that, in order to increase the manufacturing accuracy of shamelessly mating parts, they simultaneously cut out the female and female intermediate elements and use them as photocopiers for cutting, respectively, covering and covered mating parts, while cutting out the intermediate elements
