Description

Copper wire output adjusting device of guitar scale wire

Technical Field

The utility model relates to a guitar accessory production machinery, in particular to copper line output adjusting device of guitar scale line.

Background

The guitar scale line is the fret. The musical scale wire (fret) is a thin metal strip embedded at precise intervals throughout the fingerboard, most of which is usually made of nickel-silver (Nickelsilver, commonly occurring as NS) alloy (practically free of any silver), which is actually a nickel-copper alloy. Conventional alloys used to make fine scale wires are typically 18% nickel, 80% copper and other metals such as zinc, lead and cadmium. Jesca's nickel silver scale wire formula is 62% copper, 18% nickel and 20% zinc.

As shown in fig. 5, the musical scale wires have a rounded crown 1 ' on the top of a slightly thinner tang 2 ' and barbs 3 ' on both sides, each musical scale wire having a cut length corresponding to the width of the neck and then being driven into a pre-cut groove of the fingerboard. The crown 1 'is larger than the groove width, i.e. the crown 1' is wider than the tang 2 'and the tang 2' is slightly shorter than the groove width. Barbs 3 'on either side of the tang 2' ensure that the scale wire is secured in the groove.

When a cylindrical metal wire is processed into a scale line, a tang 2 ' and barbs 3 ' on two sides of the tang 2 ' are firstly rolled out from the metal wire to obtain a semi-finished scale line, then the semi-finished scale line pressed out by the roller is cut, so that the length of each scale line is matched with the width of a neck, and a handle foot 2 ' is ground, so that the width of the tang 2 ' is matched with a groove on a finger board, and the tang 2 ' is narrower than a crown 1 '.
