Planishing method for tube number soldering opening

Abstract

The invention relates to a welding seam planishing method of the pipes and the horns, belonging to the musical instrument processing field. The method comprises following steps: firstly, the horn mouth and the horn body, which are welded with each other, are sleeved on the mould which is arranged on the machine tool main shaft, and then the core clamper backs the mould; secondly, a cutter, which is provided with a press roller at the front end, is arranged at the cutter holder of the machine tool; thirdly, the cutter holder moves to the welding seam of the horn mouth and the horn body, which makes the press roller and the welding seam face to face; fourthly, the main shaft of the machine tool drives the mould to rotate, and the feeding cutter holder makes the press roller and the welding seam roll extrusion molding until the welding mouth, the horn mouth and the horn body are consistent horizontally; finally, the cutter holder and the core clamper move back, and the product is a finished product on the mould. The method in the invention has the advantages that: the design is of novelty, practicality, high productivity and good quality; the equipment using the process method is of simple structure, convenient operation and high automation level, which can make the welding seam planishing method of the pipes and the horns widely used and achieves the industrialized production of the pipes and the horns.

Description

technical field [0001] The invention belongs to the field of musical instrument processing, in particular to a flattening method for pipe number welding joints. Background technique [0002] The mouthpiece and the horn body in the horn instrument are usually installed together by welding. After the welding is completed, because the welding place is filled with solder, the welding joints of the mouthpiece and the horn body are uneven, rough and inconsistent in thickness. It not only affects the aesthetic appearance of the musical instrument, but also brings inconvenience to the next process. In order to ensure the beautiful appearance of the horn instrument and to make the next process go smoothly, it is necessary to adopt certain methods to trim the welding joints to be smooth and even. The usual method now is: the staff uses tools such as a small hammer to manually trim the weld until the weld is smooth and level. Although this method is widely used, there are many defici...

Problems solved by technology

Although this method is widely used, there are many deficiencies: 1. The manual operation takes a long time to process, the work efficiency is low, and the labor intensity is relatively high; There are certain differences in working level and working methods, so the specifications of the processed products are inconsistent, the quality is difficult to guarantee, the scrap rate is relatively high, and the industrial production of products cannot be realized
