Abstract
String-striking shaft bracket, bushing processing method, it is characterized in that the following steps are included: (1), the graphite coating layer in bushing side apply lead powder；(2), tip is cut out in bushing front end；(3), in bushing other side gluing；(4), ring-type is coiled the bushing into, the axis nail hole of pedestal is implanted into using graphite coating layer as inner ring；(5), a period of time is placed after the mixed liquor of pedestal assembly immersion silicone oil emulsion and cocounut oil crystal soda；(6), the rear punching of bushing is cut, then carries out secondary cutting bushing；(7), it is placed one week after the implantation of axis nail；(8), axis nail is extracted.Advantages of the present invention: string-striking shaft bracket of the present invention, bushing processing method, pass through the lead powder layer of setting, ensure that bushing obtains smoothness, the method that silicone oil emulsion and cocounut oil crystal soda mixed liquor are impregnated in cooperation, ensure sufficiently to adhere to lubricating fluid in bushing, it is penetrated into bushing after drying, stability to increase the lubricity of bushing and its lubricate for a long time, using the method for cutting bushing twice, ensure the soft flocks generated when will not retain drilling on bushing, pedestal is avoided because soft flocks operating has some setbacks, the torsion of axis nail is stablized.Bushing closed position is towards pedestal notch, so that it is guaranteed that the stress of bushing is reliable.
Description
Technical field
The present invention relates to Piano Fittings field, especially a kind of upright piano action bushing processing method is especially provided
A kind of string-striking shaft bracket, bushing processing method.
Background technique
Pedestal is the joint part inside hammered string instrument, turning device, clutch, damper be all followed closely by pedestal axes inside come
Operating.The quality for improving pedestal is exactly a big guarantee of hammered string instrument quality.And the quality of pedestal is dependent on the stabilization of bushing
Property, lubricity.It is particularly important for improving the sensitivity of pedestal.Hammered string instrument bushing in the prior art is difficult to ensure long-term lubrication
Stability, it is difficult to reach after test is played in 1,000,000 shakes, axis nail power still control within the scope of technical requirements.
Summary of the invention
It is an object of the invention to solve above-mentioned many technical problems, a kind of string-striking shaft bracket, bushing are provided
Processing method.
The present invention provides string-striking shaft brackets, bushing processing method, it is characterized in that the following steps are included:
(1), the graphite coating layer in bushing side applies lead powder；
(2), tip is cut out in bushing front end；
(3), in bushing other side gluing；
(4), ring-type is coiled the bushing into, the axis nail hole of pedestal is implanted into using graphite coating layer as inner ring；
(5), a period of time is placed after the mixed liquor of pedestal assembly immersion silicone oil emulsion and cocounut oil crystal soda；
(6), the rear punching of bushing is cut, then carries out secondary cutting bushing；
(7), it is placed one week after the implantation of axis nail；
(8), axis nail is extracted.
Advantages of the present invention:
String-striking shaft bracket of the present invention, bushing processing method, pass through the lead powder layer of setting, it is ensured that bushing it is smooth
Degree, the method that silicone oil emulsion and cocounut oil crystal soda mixed liquor are impregnated in cooperation, it is ensured that sufficiently adhere to lubricating fluid in bushing, seeped after dry
Thoroughly into bushing, thus the stability for increasing the lubricity of bushing and its lubricating for a long time, using cutting bushing twice
Method, it is ensured that the soft flocks generated when will not retain drilling on bushing avoids pedestal and has some setbacks because soft flocks operates, axis nail
Torsion is stablized.Bushing closed position is towards pedestal notch, so that it is guaranteed that the stress of bushing is reliable.
Specific embodiment
