Embodiment

[0031] The processed special-shaped hole is an irregular elliptical hole, such as figure 1 shown.

[0032] In this embodiment, the electrode for machining special-shaped deep holes by electric melting explosion includes a connecting section 1 of the cutter bar, a section 2 for processing the electrode round hole, and a section 3 for processing the electrode special-shaped hole; 1. It is connected sequentially by threads from top to bottom, and the center is provided with a chip removal hole 6 that runs through from bottom to bottom; the connection of each section is tight and reliable, such as figure 2 and 3 shown.

[0033] The above-mentioned electrode connection section 1 is located at the bottom of the electrode, and its outer wall is a stepped columnar shape. External threads are provided on the circumference of the lower end of the stepped columnar shape, and internal threads are provided on the circumference of the upper inner wall. The thread is connected with the s...

Abstract

The invention relates to the technical field of special machining, in particular to an electric melting explosion special-shaped deep hole machining electrode. The electrode mainly comprises an electrode round hole machining section, an electrode special-shaped hole machining section and an electrode connecting section; the electrode is provided with a guide strip and a chip removal channel; and on one hand, the guiding role is provided for a special-shaped deep hole, and on the other hand, timely cooling can be achieved, so that chips separated by explosion in machining are discharged smoothly. The electrode belongs to organic combination of electric melting explosion and deep hole machining, and an innovative technological means is provided for the special-shaped deep hole which is hardto machine; the electrode has the advantages that the dimensional accuracy and positional accuracy of the special-shaped deep hole are improved, and the high machining quality is ensured; and meanwhile, the machining time is shortened, and the machining efficiency is improved greatly.

Description

Technical field: [0001] The invention relates to the technical field of special processing, in particular to an electrode for processing special-shaped deep holes by electric melting explosion. Background technique: [0002] The irregular shape of the special-shaped deep hole and the cumbersome process make the processing difficult. At present, the typical special-shaped deep hole processing technologies mainly include: EDM, electrolytic processing, laser processing and other processing methods, but they have corresponding disadvantages in terms of processing efficiency, processing application scope and clean processing requirements, and there are many deficiencies; the new The continuous addition of high-strength, high-hardness and difficult-to-machine material parts has put forward higher requirements for the quality, processing efficiency, and processing methods of special-shaped deep hole processing. Based on the above status, in order to improve the processing efficien...
