Abstract

The invention relates to the technical field of electric spark forming, and discloses a forced cooling electric spark forming machining device for a tool electrode and a using method of the forced cooling electric spark forming machining device. The forced cooling electric spark forming machining device comprises a main body and a heat insulated steel cylinder, a spindle head is movably connected to the interior of the main body, a drill chuck is connected to the bottom end of the spindle head, and an electrode is connected to the interior of the drill chuck; and the bottom end of the spindle head is fixedly connected with a positioning ring. According to the forced cooling electric spark forming machining device for the tool electrode and the using method of the forced cooling electric spark forming machining device, through mutual cooperation of the main body, the spindle head, the drill chuck, the electrode, the positioning ring, a heat insulated groove, a top ring, a fixing ring, a bottom ring, an air outlet pipe, an air inlet pipe, an air guide pipe, a communicating pipe, a guide pipe, a sealing plug, a thermometer, the heat insulated steel cylinder, a sealing cover, a built-in pipe, a stop valve, an exhaust pipe, an air pump and an air intake pipe, the effects of rapidly cooling the tool electrode and reducing the loss of the tool electrode are achieved, and the problem that the loss amount of the tool electrode on an existing electric spark forming machine is large in the using process is solved.

Description

technical field [0001] The invention relates to the technical field of electric discharge forming, in particular to a tool electrode forced cooling electric discharge forming processing device and a use method thereof. Background technique [0002] EDM refers to the method of processing the workpiece through the electric erosion effect of the pulse discharge between the tool electrode and the workpiece electrode in a certain medium. Every time the tool electrode is used, there will be a certain amount of loss. The method of forced cooling can improve the heat absorption capacity of the tool electrode, so as to promote the deionization between the electrodes as soon as possible to maintain a good insulation state between the electrodes, reduce or even completely avoid the occurrence of arc discharge, and improve the utilization of discharge pulses. At the same time, the loss of the tool electrode is reduced. [0003] In the EDM process, if the tool electrode can be cooled qu...
