Brass-wind instrument piston and manufacturing method thereof

Abstract

The invention relates to a brass-wind instrument piston and a manufacturing method thereof. The piston comprises an outer tube body, a core and a spring tube, wherein the outer tube body is a circular metal barrel; both the core and the spring tube are integrally manufactured through plastic; the core is a plastic cylinder body and equipped with a plurality of ventilating holes; the plastic cylinder body is divided into two longitudinal parts from the middle part, and a plurality of splicing positioning pins are arranged between the two half cylinder bodies; the spring tube is cylinder-shaped, and a spring and a spring clamp are arranged in the cylinder; a piston handle is arranged at the upper end of the spring tube. The brass-wind instrument piston has the advantages that corrosion is uneasily caused, the weight is light, the key is power-saving, the production is accurately located, the performing effect can be improved, and the durability is ensued. The manufacturing method of the brass-wind instrument piston has the advantages of being simple in process, high in yield and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of musical instrument production, in particular to a brass instrument piston and a manufacturing method thereof. Background technique [0002] Piston-type buttons are widely used in brass instruments as parts for adjusting pitch. At present, the pistons of piston-type buttons are made of copper metal materials. The improvement of the pistons is limited to the processing accuracy and positioning accuracy. When making a copper piston, it is necessary to make the piston tube first, then drill holes, weld the internal vent holes, and turn the circle. The manufacturing process is complicated. The piston is required to be light in weight and flexible to bounce, so the copper pipes and vent holes are manually welded with thinner copper materials. Because the copper material is very thin, after playing for a long time, the copper material is easily damaged after being corroded by saliva and air, and then the entire...

AI Technical Summary

Problems solved by technology

Because the copper material is very thin, after playing for a long time, the copper material is easily damaged after being corroded by saliva and air, and then the entire piston key is damaged, which is the main cause of damage to brass instruments.

In addition, the accuracy of manual welding is low, the product quality is poor, the scrap rate is high, and the production efficiency is low, which greatly increases the production cost of the piston.
