Abstract
The invention relates to a prestress piano sound plate and relative production, wherein the rib of the sound plate is straight before adhered with a resonance plate, the curvature radius of string code before adhered with the resonance plate is larger than the radius of the arc shape of the resonance plate. And the production is characterized in that the resonance plate is adhered with the rib, died and shaped by a mould with preset arc, to form curvature shape as the mould die chamber. Compared with prior arc rib of sound plate, the inventive rib is straight before adhered with the resonance plate, to save material, make production easy, and support batch production. And the prestress in the string code and the resonance plate can represent resonance effect of the sound plate better, and reduce the loss of bass harmonic wave.
Description
Technical field
The present invention relates to the musical instrument manufacturing technology, be specifically related to piano soundboard and job operation thereof.
Background technology
Piano soundboard is the critical component of the resonance system of piano.Soundboard is made up of sounding board, stall bars, string sign indicating number, frame and five parts of noise reduction shelves, and profile is vaulted shape.The effect that the soundboard profile is vaulted shape mainly is to strengthen the downforce that soundboard carries string.The job operation of existing piano soundboard: the stall bars that process the band arc with production miller---sticks with glue the agent gummed with sounding board and the stall bars of being with arc and the string sign indicating number is installed---with frame, noise reduction shelves and sounding board and stall bars gummed---.There are two aspect deficiencies in the job operation of existing piano soundboard: the one, and material is taken a lot of work, is taken in the processing of the stall bars of band arc; The 2nd, find in test data from production run for many years and the field feedback that the method for making of existing soundboard is unfavorable for the resonance effect of soundboard, particularly the harmonic components of bass in the influence.
Summary of the invention:
The purpose of this invention is to provide a kind of working (machining) efficiency height, piano soundboard that resonance effect is good.
Technical scheme of the present invention is:
A kind of piano soundboard is made of sounding board, stall bars, string sign indicating number, frame and noise reduction shelves, and the soundboard profile is vaulted shape, it is characterized in that: described stall bars are rectilinear form before gluing together with sounding board; Before described string sign indicating number and the sounding board gummed, the vaulted radius-of-curvature of string sign indicating number and sounding board faying face is greater than the vaulted radius-of-curvature of sounding board.
The job operation of above-mentioned piano soundboard and step, comprise, the gummed of gummed, frame, noise reduction shelves and the sounding board and the stall bars of the manufacturing of sounding board and stall bars, sounding board and stall bars, string sign indicating number are installed, it is characterized in that: described stall bars are rectilinear form before gluing together with sounding board, with having the mould compression molding of setting arc, make sounding board and stall bars gummed back form the curve form approximate in the time of sounding board and stall bars gummed with mold cavity.
The stall bars that the present invention uses with sounding board gummed before be rectilinear form, therefore the stall bars of the band arc of using with existing soundboard are compared, materials economize, easy to process, are more conducive to batch process.Before string sign indicating number and the sounding board gummed, the vaulted radius-of-curvature of string sign indicating number and sounding board faying face is greater than the vaulted radius-of-curvature of sounding board, both glue together the back and have an internal stress, survey factually, soundboard with the inventive method processing, particularly prestressed effect in string sign indicating number and the sounding board helps the performance of the resonance effect of soundboard, and middle bass harmonic components loss is few.
Description of drawings
Fig. 1 is the front view of the structural representation of piano soundboard of the present invention;
Fig. 2 is the A-A view of structural representation of the present invention;
Fig. 3 is the B-B view of structural representation of the present invention.
Embodiment
As shown in Figure 1, 2, 3, piano soundboard comprises sounding board 1, stall bars 2, string sign indicating number 3, frame 4 and noise reduction shelves 5, contour structures after its moulding and existing soundboard no significant difference.But described stall bars 2 are rectilinear form before gluing together with sounding board 1; Before described string sign indicating number 3 glued together with sounding board 1, the vaulted radius-of-curvature of string sign indicating number 3 and sounding board 1 faying face was greater than the vaulted radius-of-curvature of sounding board 1.
The job operation and the step of piano soundboard are as follows:
A. sounding board 1 and stall bars 2 manufactures;
B. the compression molding and the gummed of sounding board 1 and stall bars 2;
C. the gummed of frame 4, noise reduction shelves 5 and sounding board 1 and stall bars 2;
D. the installation of string sign indicating number 3.
Claims (1)
1. a piano soundboard is made of sounding board, stall bars, string sign indicating number, frame and noise reduction shelves, and the soundboard profile is vaulted shape, it is characterized in that: described stall bars are rectilinear form before gluing together with sounding board; Before described string sign indicating number and the sounding board gummed, the vaulted radius-of-curvature of string sign indicating number and sounding board faying face is greater than the vaulted radius-of-curvature of sounding board.
