Warning and dotting device for electrical discharge machine

Abstract

The invention provides a warning and dotting device for an electrical discharge machine, wherein, a detection anode and a detection cathode of the electrical discharge machine are connected with an anode and a cathode of an operating power supply of a solenoid valve respectively, and the lower end of a cylinder at one side of the solenoid valve is equipped with a felt fixture with printing ink. The device has the beneficial effects that when the electrical discharge machine gives an alarm, the anode and the cathode of the electrical discharge machine are conducted so as to electrify the solenoid valve for running, and the felt fixture with the printing ink is rapidly closed to remain an ink imprint at the part at which an electric wire is broken; and when the defective wire in which the ink imprint is remained reaches the wire-winding position on the tail end of an extruder, an operator can easily get rid of the defective product, thus reducing unnecessary procedures and improving operating efficiency.

Description

technical field [0001] The invention relates to a spark machine device, in particular to a spark machine alarm marking device. Background technique [0002] Generally, when the wires are produced by the extruder, if there are defective points caused by wire breakage or spark machine breakdown, they need to be removed and scrapped. Because the extruder is running at high speed, the line speed reaches more than 200m per minute. When the spark machine alarms, the operator who takes up the line after the extruder has to stop and take up the line to find out the bad points and eliminate them. Because the speed is too fast, the bad points sometimes disappear. It is not obvious enough, so that the bad points cannot be removed in time, and the bad points can only be reworked after the shaft is lowered to remove the bad points. Therefore, a process will be added, and defective products will easily flow into the next process. Contents of the invention [0003] In view of the above...
