A Rotary Tool Electrode for Electromelting Explosion Machining of Special-shaped Hole with Large Length-to-Diameter Ratio

Abstract

The invention relates to the technical field of special processing, in particular to a rotary tool electrode used for electromelting explosion processing of special-shaped holes with a large length-to-diameter ratio. In order to solve the difficulties in electrode preparation in the process of irregular special-shaped deep hole processing in the current technology, and the difficulty of chip removal and cooling in the process of special-shaped deep hole processing. The technical scheme adopted in the present invention includes an electrode rotating part and an electrode body part; the structure of the electrode body part is a stepped cylinder, the axial center of the stepped cylinder is provided with a through internal chip removal channel, and the large-diameter end circumference of the front end of the stepped cylinder There are several guide strips evenly distributed on the top, the small diameter end of the rear end is the electrode connection section, the middle of the cylinder is provided with a concave platform, the concave platform communicates with the inner chip removal channel, and the stepped cylinder between the concave platform and the electrode connection section There is a plane, and the inner chip removal channel in the middle of the concave platform of the stepped cylinder is provided with a connecting hole 2. The electrode rotating part is arranged on the concave platform of the cylinder through the connecting pin and rotates through the connecting pin.

Description

Technical field: [0001] The invention relates to the technical field of special processing, in particular to a rotary tool electrode used for electric melting and blasting processing of special-shaped holes with a large aspect ratio. Background technique: [0002] With the development of the machinery manufacturing industry, products are frequently updated, and special-purpose large aspect ratio special-shaped deep holes can be seen everywhere in the modern deep hole field, such as electromagnetic rails, rocket launchers, crankshaft oil holes, etc.; Transmission media, energy, information and other aspects play an irreplaceable role in other types of holes. However, the special-shaped deep hole has irregular hole shape, high processing difficulty and large processing workload. It has become a key process in mechanical processing. There are many difficulties in the processing process, such as: complex cross-sectional shape, relatively large length and diameter, and chips pass...
