Testing Wire

The apparatus is used to form a head on a length of wire. Any flaws in the wire are magnified in the head and can be examined under a microscope.

Base 11 of apparatus 10 is provided with a removable split bushing 12 which receives and grips a length of wire 14 to be tested.

Portion 14a protrudes above the top surface bushing 12. Head height pad 16 is mounted adjacent 14 and serves as a step to limit the stroke of plunger 18. To test a wire, a length of wire is clamped in bushing 12 with a portion protruding above pad 16. For example, with. 020 inch diameter wire, a pad having a height of. 010 inch is used with the wire protruding above the pad approximately. 060 inch.

Plunger 18 is driven down to the position shown in dotted lines producing a head 14b, also shown in dotted lines. The resultant length of headed wire is then removed and viewed under a microscope. Minute flaws, such as seams, cracks, localized variations in hardness due to scalping, drawing, etc., are magnified in the head making the examination simple, complete, and accurate.
