Description

Electrode for discharging of electric spark equipment

Technical Field

The utility model relates to an electric spark machining electrode makes technical field, concretely relates to electrode that electric spark equipment discharged usefulness.

Background

The electric discharge machining process is generally applied to machining of parts which have relatively high hardness and in which a material must have conductivity, and is widely used for machining of die parts. The discharge electrode is the main actuator of electric discharge machining, and corresponds to the tool of a cutting machine. Factors that affect the quality of electric discharge machining include:

1. the position accuracy of the discharge electrode when mounted on the electric discharge machine includes levelness and verticality. In order to ensure the position precision, a dial indicator is adopted to level an electrode arranged on a main shaft of the electric discharge machining. As shown in fig. 1, the conventional electrode 4 is mostly cylindrical, and the side surface thereof is a curved surface, and it is difficult to ensure that the pointer is perpendicular to the side surface of the electrode when a dial indicator is used for calibration, so that an error is generated in the positional accuracy of the electrode 4, thereby affecting the processing quality.

2. The timeliness of discharging carbon slag particles generated in the process of electric spark machining. Carbon residue produced by electric spark machining is discharged in time, so that carbon deposition can be formed on a machined workpiece, on one hand, the machining quality of parts can be influenced, and an electrode is easily abraded; on the other hand, the production efficiency is lowered. In order to remove the carbon slag in time, flushing liquid is sprayed into the machining position from top to bottom during electric spark machining, so that the carbon slag is flushed away. As shown in fig. 1, the outer side surface of the conventional electrode discharge end 41 and the electrode 4 are integrally cylindrical, and when machining is performed, especially for machining a deep groove or a long hole, the outer side surface of the electrode 4 is attached to the inner side surface of the machined groove hole, and when machining is performed to a certain depth, the flushing liquid cannot effectively contact with carbon slag, so that carbon slag particles generated between the electrode discharge end 41 and the machining plane 51 on the machined part 5 cannot be discharged in time.
