Description
Technical field
The present invention relates to piano processing equipment, and in particular to piano string grind embossing device, be related to install additional the device around string
Machine and its around string method.
Background technology
Existing piano string does not carry out steel wire when copper wire is wrapped on steel wire mill flower, steel wire surface very light
It is sliding, from closely snarling when preventing the copper wire be wrapped on steel wire, when string is suspended on piano since string stress is exceptionally straight
And occur and gap is produced between copper wire and steel wire, since steel wire surface is smooth, between copper wire and steel wire, frictional force is inadequate, so that
Copper wire can be made to occur returning pine with steel wire, have impact on the tone color of piano.If winding pulling force, the copper wire that can make are increased when copper wire is wound
Deformation is so as to can also influence the tone color of piano string.
To solve the above-mentioned problems, the prior art is to carry out mill flower to steel wire using file, needs to take in this way
File be pressed on the steel wire of rotation to steel wire grind spend, steel wire rotate bounce can be produced during string so that file is in steel
Colored steel wire cannot be ground in bounce between silk, this mode is relatively backward, and grinds and spend effect bad, and mill spends uneven damage steel
Silk.
Also use steel wire of the section for polygon so that when copper wire is wrapped on this steel wire, copper wire and polygon steel
The flanging stress of silk increases and is not easy to return pine, but this steel wire, due to being polygon, when playing, hammerhead taps steel wire and produces
Tone color it is bad.
The equipment to piano string mill flower is not present in the prior art.
