Spark-erosion perforating machine guide device

Abstract

The invention relates to a guide device for an electric spark perforator, which includes a guide, a guide seat and a guide bracket. The upper section matches the middle section of the guide, the guide bracket includes a positioning through hole, the upper part of the guide seat is set above the positioning through hole, and the lower part of the guide seat matches the positioning through hole, and is set in the cavity of the guide seat The middle section of the guider is located in the positioning through hole, and the lower section of the guider is located below the positioning through hole; there is a circle of water tank outside the middle section of the guider, and the guide bracket is provided with a water inlet hole that is connected to the water tank, and the lower end surface of the water tank passes to the guider. A plurality of water channels are arranged through the bottom of the lower section, the water inlet holes are connected with the water channels, a center hole is arranged in the center of the guide, and the water channels are arranged outside the center hole. The invention can concentrate flushing of multiple water channels, increase the water pressure, prevent the water flow from spilling outwards, and ensure the chip flushing effect.

Description

technical field [0001] The invention relates to a guide device for an electric spark punching machine. Background technique [0002] An EDM piercer is a device that punches holes in metal or conductive materials through the principle of discharge corrosion. The device generally uses hollow copper tubes or solid copper wires as processing electrodes. During the processing, holes are drilled on the processed workpiece. During the drilling process, the temperature will become higher, and there will be slag on the perforated workpiece. Currently, flushing water is used to cool down, and Water is used to flush out slag from the hole of the workpiece. A water tank is installed on one side of the EDM piercer. A central hole is set in the center of the guide. The water in the water tank cools down through the center hole and the slag is flushed out. When the workpiece When the perforation does not penetrate, it is easy for water to recoil upward from the center hole of the guide, a...

During the processing, holes are drilled on the processed workpiece. During the drilling process, the temperature will become higher, and there will be slag on the perforated workpiece. Currently, flushing water is used to cool down, and Water is used to flush out slag from the hole of the workpiece. A water tank is installed on one side of the EDM piercer. A central hole is set in the center of the guide. The water in the water tank cools down through the center hole and the slag is flushed out. When the workpiece When the perforation does not penetrate, it is easy for water to recoil upward from the center hole of the guide, and the chip flushing effect is poor; Director is working
