Hole-drawing machine for saxophone body

Abstract

The invention relates to a hole-drawing machine for a saxophone body, which comprises a base, an electric cabinet, a tube clamping and rotating mechanism, an extrusion disc mechanism and an extrusion drag link mechanism, wherein the electric cabinet is mounted at the lateral back end of the base, the extrusion drag link mechanism is mounted on the base, the extrusion disc mechanism opposite to the extrusion drag link mechanism is mounted in the middle of the base below the extrusion drag link mechanism, and the tube clamping and rotating mechanism opposite to the extrusion disc mechanism is mounted at the front end of the base. In the invention, the tube clamping and rotating mechanism, the extrusion disc mechanism, a double-shaft milling and flattening mechanism and the extrusion drag link mechanism are all mounted on the base, the four mechanisms interact with each other to machine all sound holes in the saxophone body, and each sound hole is machined at high precision and is automatically subject to a cutting process after hole drawing, thereby effectively ensuring the height and the expansion of the sound hole wall, shortening the machining cycle, saving the cost, facilitating the subsequent machining procedure and enabling the saxophone to make more accurate and wonderful sound.

Description

technical field [0001] The invention belongs to the field of musical instrument processing equipment, in particular to a hole pulling machine for a saxophone body. Background technique [0002] Saxophone, also known as saxophone, is played with a single reed. The structure and range of the opening and closing sound holes are similar to those of the clarinet. The body is made of copper, so it can also be a brass instrument. Its timbre is between woodwind instruments and brass instruments. It has the loudness of brass music and the softness of woodwind music. The timbre changes beautifully, deep and calm, full of emotion, soft and sad, and can not only play classical music well , and better at playing jazz music and light music, it is currently a popular musical instrument for people in the music industry. Its structure usually includes: a pipe body, a Bohm system key system and a mouthpiece. The diameter of the pipe body gradually increases from the end where the mouthpiece ...

AI Technical Summary

Problems solved by technology

In the hole drawing process during processing, the operator first puts the truncated cone-shaped drawing block into the pipe body, and then uses the pull rod to pull the truncated-cone-shaped drawing block outward along the radial direction of the pipe body, so that the pipe body wall around the preset hole of the pipe body Extend outward to form sound holes. After all the sound holes are processed, the next step of incision processing is carried out. However, the hole drawing process of the musical instrument factory is currently processed by hand, which not only cannot guarantee the accuracy of the sound holes, but also makes the height of the sound holes not meet the requirements. , but also delayed the production cycle, resulting in a large number of defective products, increasing the cost of manufacturers
