Description
Technical field
The present invention relates to the pre- whole sound pricker machines of a kind of row's needle assemblies and piano hammerhead.
Background technique
In the production process, due to the extruding by hammerhead wooden core, the density of felt will increase piano hammerhead, especially exist
Mallet Guan Chu；Those issue the hammerhead of sharp tone color, usually because the hardness of mallet hat is very high and no elastic；In order to allow every frame steel
The tone color that qin can all have can measure the hardness number of piano hammerhead felt in process of production, when felt hardness is more than index
When, the method taken first is the two sides of needle thorn hammerhead, reduces the tension of hammerhead two sides, and the tension for enabling mallet to be preced with is alleviated, table
Face pulling force reduces, and the tension decline of hammerhead felt, hammerhead felt elasticity is released, and hammerhead has obtained elastic buffer when hitting string,
Make hammerhead hit string and last slightly to extend, high order partials are reduced, and tone color can become fine and smooth and full.
General man-hour manually hand-held row needle tool carries out pricker in the prior art, artificial to pierce since the density of hammerhead felt is larger
Needle is very hard, and efficiency is very low, and not can guarantee consistency.
Summary of the invention
The present invention in view of the deficiency of the prior art, provides a kind of time saving and energy saving and consistency preferable piano string
