Embodiment Construction

[0014] Include the following steps,

[0015] 1) Material preparation: choose the whole piece of wood;

[0016] 2) Mark the line: first make the cornerstone, draw an equilateral hexagon and a center line on one end of the big head, and then cross the line and draw an equilateral hexagon on the other end of the small head.

[0017] 3) Cutting and sawing the shape: After drawing the hexagonal platform line of the piano tube, saw the outer six sides, and at the same time drill and chisel the inner hexagon to a semi-rough product;

[0018] 4) Rough and fine planing shape: rough and fine planing the outer hexagonal edge, milling, shoveling, filing the inner hexagonal edge, and processing the whole cylinder into a semi-finished product of the inner hexagonal table;

[0019] 5) Finishing: milling, filing, digging, chiseling, large and small inner openings and inner semicircular arcs at both ends of the light piano tube;

[0020] 6) Grinding: Milling the outer waist arc of the piano ...

Abstract

The invention relates to a manufacturing process of an Erhu cylinder, which comprises the steps of preparing materials: selecting the whole piece of wood; marking: firstly making a foundation, marking a hexagon and a center line on the big head end, and then crossing to the small head end for marking a hexagon with coaxial two ends and parallel edges; cutting the shape: cutting off the outer six edges after marking the hexagonal frustum lines of the cylinder, and simultaneously drilling and punching the hexagon to a semi rough finished product; rough and fine planing the shape: rough and fineplaning the outer hexagonal edges and milling, shoveling and filing the inner hexagonal edges and machining the whole cylinder to a semi fine finished product in a hexagonal frustum in the inner chamber; finishing: milling, filing, digging, punching and polishing two ends to be big and small inner-sucking inner semicircular arcs; grinding: milling the outer waist arc of the cylinder, grinding theouter opening of the big head, the outer six surfaces of the cylinder, the waist arc and the six edges; and stringing: flattening the arc and trimming the three strings to complete the manufacture ofthe cylinder. In the invention, the problems of tone quality, resonance and impure pitch and bass areas of the traditional spliced Erhu cylinder are solved and the cylinder has the characteristics ofnatural tone, tone quality and resonance and attractive appearance, and is processed delicately.

Description

technical field [0001] The invention relates to a manufacturing process of an erhuqin tube. Background technique [0002] The traditional erhu is mostly made of wood in the shape of a hexagonal platform, one end is a large hexagon, and the other is a small hexagon. Defects of resonance, impurity in the high and low ranges. Contents of the invention [0003] The object of the present invention is to provide a manufacturing process of the erhu piano tube, which has the characteristics of natural timbre, sound quality and resonance, and is exquisitely processed and beautiful. [0004] The technical solution for achieving the above purpose includes the following steps: [0005] 1) Material preparation: choose the whole piece of wood; [0006] 2) Mark the line: first make the cornerstone, draw an equilateral hexagon and a center line on one end of the big head, and then cross the line and draw an equilateral hexagon on the other end of the small head. [0007] 3) Cutting an...
