Description
Technical Field
The utility model relates to the technical field of bamboo flute manufacturing, in particular to a bamboo flute (bamboo wood) inner diameter curve cutter.
Background
The bamboo flute in China is obtained from natural bamboo materials, and the inner diameter and the curve of the bamboo materials are not uniform. The sound level of the bamboo flute is largely dependent on the size of the inner diameter and the curve of the inner diameter. The non-uniformity of the original material causes the situation that octave inaccurate sound appears very easily in the process of manufacturing bamboo flute, and the traditional technology is mainly manufactured by selecting materials with the closest specification from a large number of bamboo materials, and other materials with poor inner diameters can only be discarded in white.
The traditional manufacturing mode is that the approximate materials can be selected only through the screening mode, and the bamboo materials with other nonstandard inner diameters can only be abandoned, so that a plurality of bamboo materials with nonstandard inner diameters can be wasted and cannot be utilized efficiently, and even if the standard bamboo materials are selected, the problem of inaccurate tone can be caused by individual differences during manufacturing. Meanwhile, the bamboo flute is made of natural materials, repeated debugging is conducted on each flute, and standardized mass production of bamboo is affected.
In order to solve the problem that the inner diameter of the bamboo wood does not reach the standard, a great number of flute making machines have made a great deal of attempts, such as chiseling through bamboo joints with files and the like and extending into the inner wall of the bamboo wood through sand paper rods and the like, and polishing the inside of the bamboo wood. The utility model discloses a bamboo wood joint removing cutter system for furniture, which comprises a cutter bar and a cutter head, wherein the cutter bar is in circumferential rotation and axial sliding connection with a frame, the cutter head is arranged at the top end of the cutter bar in a sliding manner along the direction perpendicular to the axis of the cutter bar, the cutter head is in a movable structure, the cutter head is in a contracted state in the process of stretching into a bamboo tube, interference between the cutter head and the inner wall of the bamboo tube is avoided, after the cutter bar is in place, the cutter head stretches out, and the cutter blade is just flush with the inner wall of the bamboo tube under the action of a limiting part, so that the cutting surface is flush with the inner wall of the bamboo tube, and the limiting part has the effect that the cutter blade can just protrude to the position flush with the inner wall of the bamboo tube no matter how the inner diameter of the bamboo tube changes, so as to adapt to cutting of bamboo wood with different tube diameters.
