Description

Cutting and stamping die for guitar scale line

Technical Field

The utility model relates to a guitar accessory production field, in particular to cutting stamping die of guitar scale line.

Background

The guitar fret is the fret. Fret (fret) refers to a thin strip of metal embedded at precise intervals throughout the fingerboard, most fret materials being made of a nickel-silver (Nickelsilver, commonly occurring as NS) alloy (practically free of any silver), which is a substantial composition of nickel and copper alloys. Conventional alloys used to make good quality wire are typically 18% nickel, 80% copper and other metals such as zinc, lead and cadmium. Jesca's nickel silver wire formulation was 62% copper, 18% nickel and 20% zinc.

As shown in fig. 4, the fret wires have a circular fret crown 1 ' on the top of a thinner tang 2 ' and barbs 3 ' on both sides, and each fret wire has to be cut to a length that matches the neck width and then be 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 fret is secured in the groove.

When a cylindrical metal wire is processed into a finished product wire, 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 product wire, then the semi-finished product wire pressed out by a pair of rollers is cut, the length of each product wire is matched with the width of a neck, and a handle foot 2 ' is ground to enable the width of the tang 2 ' to be matched with a groove on a finger board, so that the tang 2 ' is narrower than a crown 1 '.
