Trumpet nozzle pipe molding machine tool

Abstract

The invention relates to a trumpet nozzle pipe molding machine tool, which comprises a workbench, an electric control box, a propelling cylinder, a material feeding mechanism, an outer diameter trimming mechanism, a nozzle pipe clamping mechanism, a cutting mechanism and a positioning cylinder, wherein the electric control box is arranged at any side edge of the workbench; the propelling cylinder is arranged at the left end of the workbench; the outer diameter trimming mechanism and the nozzle pipe clamping mechanism are arranged in turn on the right side of the propelling cylinder; and the material feeding mechanism is arranged on the outer side of the outer diameter trimming mechanism. The machine tool has a simple structure, combines the cylinder with electric control equipment, realizes trimming of the inner diameter and the outer diameter of the nozzle pipe and length processing, automatically finishes feeding, inner diameter trimming, outer diameter trimming and length trimming, has high control level, makes the inner diameter and the outer diameter of a processed nozzle pipe more uniform, has more accurate length, lowers the working intensity of operating personnel, improves working efficiency and ensures sounding of an assembled trumpet.

Description

technical field [0001] The invention belongs to the field of musical instrument processing equipment, in particular to a trumpet mouthpiece tube forming machine tool. Background technique [0002] The trumpet is a high-pitched brass instrument with a high-pitched and loud sound, and is widely used in the performance of orchestras and jazz bands. The general structure of the trumpet is: including the mouthpiece, the horn body and the bell mouth, a group of buttons are arranged on the horn body, the horn body is composed of a series of straight tubes, and a "U" bend is passed between each straight tube connect. The common trumpet has several adjustment modes such as B flat, C tune, E flat tune and A tune. The realization of various tuning modes depends on the length and inner diameter of the trumpet. The diameter and length of each section of pipe have high requirements. Once the diameter of the pipe is not suitable, there will be a gap when they cooperate with each other, w...

AI Technical Summary

Problems solved by technology

Generally, the inner diameter is uniformly trimmed by a hydraulic press during processing, and then the two ends of the nozzle tube are cut by a lathe, but it is difficult to ensure the length of the nozzle tube and the sound of the trumpet after installation.
