Description
Technical Field
The invention belongs to the field of protection of perforators, and particularly relates to an electric spark perforator with external protection measures
Background
The electric spark perforating machine is used for machining small and medium-sized dies, and is characterized in that the machining is not limited by the hardness of metal materials, and the hole patterns required by the machining can be machined after the template is quenched, so that the quality is ensured, and the service life is prolonged. The tool electrode material can be steel, cast iron or copper. Piercing machines are broadly divided into two types, one being a liquid piercing machine and the other being a gas piercing machine, depending on the medium used. The electric spark perforating machine is also called as electric spark perforating machine, electric spark small hole machine and electric spark fine hole discharge machine, and its working principle is that the continuous up-and-down vertical movement of fine metal copper tube is used as electrode to make pulse spark discharge to remove metal and make formation. Unlike electric spark wire cutting machine and forming machine, the electric pulse electrode is hollow copper rod and the medium passes through the pores in the middle of the copper rod hole to cool and remove chip. The electrode and the metal are discharged to generate high-temperature corrosion metal to achieve the purpose of perforation, and the electrode and the metal are used for processing pores of superhard steel, hard alloy, copper, aluminum and any conductive substances.
1. Conventional perforators typically have one end of the electrode inserted directly into the electrode holder and the other end inserted into the bottom electrode holder, and no guard between the two electrode holders, because the spark-perforator is powered by electricity and dangerous if inadvertently touched by a person when in proximity.
