Abstract
The invention discloses a kind of piano peg manufacture crafts, the raw material for making peg are carried out blanking, first rear car small round head and the big round end of vehicle, then carry out tumbling and centreless grinding to the axis after turner, then carry out the side of pounding to axis again, and feel relieved；It is drilled to axis with drilling machine, and removes flash removed；Axis after drilling is electroplated, thread finally is carried out to axis.Present invention process must not have solids or decortication phenomenon so that the square toes being exposed are smooth, glittering using square toes equipment is pounded after electro-coppering nickel chromium triangle；Thread again after plating so that screw thread is clear, and being screwed on string shaft securely enhances, not easy to slip teeth.
Description
Technical field
The present invention relates to piano manufacturing technology field, specifically a kind of piano peg manufacture craft.
Background technology
Currently on the market with the peg of single big product, the head for the side of pounding is rough, and what also can obviously be seen after plating comes out, shadow
While ringing visual appearance, when being rotated using specific purpose tool so that surface has electroplated layer to fall off；Screw thread is to use thread rolling technique
, it is electroplated after first thread rolling, the original depth of screw thread is just shallow, plates more shallow after plating, and it is inadequate to be screwed in fastness on string shaft, is easy
Sliding tooth.
Invention content
The purpose of the present invention is to provide a kind of piano peg manufacture crafts, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the present invention provides the following technical solutions：
A kind of piano peg manufacture craft, specific make step are as follows：
（1）The raw material for making peg is subjected to blanking by punching machine, is used in combination mold to be fixed, prepares processing；
（2）Turner is carried out to the axis fixed, vehicle small round head is used in combination R rule to test；
（3）After the assay was approved, turner again is carried out to the axis after turner, the big round end of vehicle is used in combination R rule to test；
（4）After the assay was approved, it is placed on roller, tumbling is carried out to the axis after turner, two round end surfaces are without tool marks after tumbling；
（5）Centreless grinding is carried out to the axis after tumbling using grinding machine, its surface roughness is made to reach Ra1.6；
（6）It using easy forging machine and pounds square toes equipment the side of pounding is carried out to axis, the side's of pounding rear surface roughness reaches Ra1.6；
（7）It feels relieved to the axis of processing, for centering eye in taper planar central, center punch angle is 120 °；
（8）It is drilled to axis with drilling machine, hole will be got through completely, and remove flash removed；
（9）Axis after drilling is electroplated, last layer cupro-nickel chromium alloy layer is electroplated；
（10）Thread finally is carried out to axis, it is desirable that it is 0.04 along taper, and screw thread is clear.
Compared with prior art, the beneficial effects of the invention are as follows：Present invention process uses and pounds square toes equipment, electro-coppering nickel chromium triangle
After must not have solids or decortication phenomenon so that the square toes being exposed are smooth, glittering；Thread again after plating so that screw thread
Clearly, being screwed on string shaft securely enhances, not easy to slip teeth.
Description of the drawings
Fig. 1 is the structural schematic diagram for the piano peg that present invention process makes.
Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In the embodiment of the present invention, a kind of piano peg manufacture craft, specific make step is as follows：
（1）The raw material for making peg is subjected to blanking by punching machine, is used in combination mold to be fixed, prepares processing；
（2）Turner is carried out to the axis fixed, vehicle small round head is used in combination R rule to test；
（3）After the assay was approved, turner again is carried out to the axis after turner, the big round end of vehicle is used in combination R rule to test；
（4）After the assay was approved, it is placed on roller, tumbling is carried out to the axis after turner, two round end surfaces are without tool marks after tumbling；
（5）Centreless grinding is carried out to the axis after tumbling using grinding machine, its surface roughness is made to reach Ra1.6；
（6）It using easy forging machine and pounds square toes equipment the side of pounding is carried out to axis, the side's of pounding rear surface roughness reaches Ra1.6；
（7）It feels relieved to the axis of processing, for centering eye in taper planar central, center punch angle is 120 °；
（8）It is drilled to axis with drilling machine, hole will be got through completely, and remove flash removed；
（9）Axis after drilling is electroplated, last layer cupro-nickel chromium alloy layer is electroplated；
（10）Thread finally is carried out to axis, it is desirable that it is 0.04 along taper, and screw thread is clear.
Piano string axle construction made from technique is secured through the invention, not easy to slip teeth, and using effect is good；It is set using square toes are pounded
It is standby, must not there are solids or decortication phenomenon after electro-coppering nickel chromium triangle so that the square toes being exposed are smooth, glittering；After plating again
Thread so that screw thread is clear.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
