Abstract

PURPOSE:To make shape of cut end portion better and automatic and smooth insertion of wire by cutting an electrode wire instantaneously by non-contact spark discharge. CONSTITUTION:A spark generating device 31 is designed so that a pair of spark generating electrodes 32 are oppositely arranged on both sides of an electrode wire 2 at a predetermined distance. When electrical discharge is generated by a discharge circuit 40, it is introduced to the electrodes 32 by electric circuits 39 and spark is generated. By this spark, the electrode wire 2 is instantaneously cut. The above action is repeated each time when cutting is necessary. The cut end portion of the cut wire has no burr or so and automatic insertion of wire can be made smoothly.

Conventional automatic wire cutting! Since the cutter was operated with a KW of dH or higher, the biggest drawback was that as the number of cuts was increased, the cutting edge of the cutter would wear out and gradually become dull, leading to automatic insertion failure. This tendency becomes more pronounced as the diameter of the electrode wire used becomes larger, so it is necessary to always maintain the sharpness of the cutter at its best.

In other words, as long as cutting is done with a cutter, there is a limit to the lifespan of the blade, and in particular, ha
The +f& wire must be cut sharply so that so-called "paris" do not occur at the cut portion. If "paris" occur, they will get caught in the initial hole and become a major cause of poor insertion. Therefore, conventional automatic wire cutting devices have the disadvantage that the cutter is not sharp enough to cause "burr", which causes distortion, which often causes problems in automatic wire insertion.
