Embodiment Construction

[0031] Such as Figure 5 to Figure 8 Shown in one of them, a kind of manufacturing method of piano sound source component of the present invention, this manufacturing method comprises the following steps:

[0032] 1) Production of the soundboard: the soundboard is processed and formed on the soundboard cold-pressing and shaping machine 1. The soundboard cold-pressing and shaping machine 1 has a lower mold 11 and an upper mold 12. The upper mold 12 is driven by the lifting driver 13 on the lower mold 11. Do the lifting movement directly above, the upper end surface of the lower mold 11 is provided with a slot 111 for placing the bridge 2, and the lower end surface of the upper mold 12 is provided with a plurality of pressing plates 14 matching the shape of the ribs 3 at intervals, and the sound board The specific process of making is as follows,

[0033] 1-1. Put the bridge 2 in the slot 111 of the lower mold 11, wherein the upper end of the bridge 2 extends out of the upper s...

Abstract

The invention discloses a manufacturing method of a piano sound source component. The manufacturing method comprises the following steps: (1) a soundboard is produced, namely carrying out one-time machining forming on a soundboard through a soundboard cold-pressing shaping machine, wherein the soundboard cold-pressing shaping machine comprises a lower mold and an upper mold, the upper mold is driven to by a lift driver to do lifting motion right above the lower mold, a slot for arranging a bridge is formed in the upper end surface of the lower mold, and a plurality of pressure plates matched with the shapes of wall bars are arranged on the lower end surfaces of the upper mold at intervals; and (2) the soundboard is fixedly bound with a back frame. The manufacturing method has the beneficial effects of high production efficiency and machining precision.

Description

technical field [0001] The invention relates to the field of pianos, in particular to a method for manufacturing a piano sound source component. Background technique [0002] The sound source component is a key part of the piano resonance system, such as figure 1 or figure 2 As shown, the sound source component mainly includes a back frame 01 and a sound board 02 , the top of the back frame 01 is fixed with a peg board 03 , and the sound board 02 is fixed under the peg board 03 . The manufacturing method of the sound source component mainly includes two steps, the first step is to manufacture the sound board, and the second step is to glue and fix the sound board on the back frame. [0003] Such as image 3 or Figure 4 As shown, the soundboard 02 includes a resonance board 021, a bridge 022 and a rib 023, and the bridge 022 and the rib 023 are respectively fixed on the two surfaces of the resonance board 021 by gluing. In the prior art, the bridge and the ribs are res...
