Work.
The processing method, the insert have a targeting part, have in the main body be engaged with targeting part and
The pilot hole communicated with through hole.
The processing method, the targeting part keep stitching state with pilot hole in assembling.
The processing method, the circular arc of the arc fillet R are not more than 3.0mm.
The processing method, is specially：
1) according to the distribution situation of arc groove, type tire is cut into main body and insert two parts from the punishment of end face cell wall, and protect
Card main body and insert keep stitching state in assembling；
2) processing of main body
2.1) planing：Six face of length of press-type tire pattern size planing operation main body；Grind high two face and the length of main body
Simultaneously stay 0.6-0.8mm surpluses in two faces；
2.2) it is heat-treated：Quench tempering 35-39HRC；
2.3) grinder：To parallel, two face of length of grinding main body ensures length to parallel in high two face of grinding main body
Two faces are vertical with high two face；
2.4) right boring：By the datum hole in the pattern size main body of main body；
2.5) wire cutting：By the datum hole centering of right boring, arc groove and the position for being R0.4 by the pattern cyclotomy angle of main body
In being used to assemble the through hole of insert, and guarantee type face tolerance, and the matching relationship of intermediate throughholes and insert in main body；
3) processing of insert：
3.1) planing：By high two face of pattern size planing operation insert, mill surplus 0.6-0.8mm is stayed；
3.2) it is heat-treated：Quench tempering 35-39HRC；
3.3) grinder：By high two face of pattern size grinding insert；
3.4) right boring：By the interstitial hole of pattern size insert, ensure tolerance dimension；
3.5) wire cutting：By the interstitial hole centering that right boring is made, insert shape is processed by the pattern size of insert, ensures edge
The matching relationship of block and main body；
4) assemble, repair the binding face for grinding main body and insert, the insert processed is assembled in main body by pressing mode
Through hole in, be finally completed the processing of the type tire.
The invention has the advantages that：
The characteristics of a kind of minimum R angle-style tire processing method of the present invention efficiently uses arc groove on type tire, by type tire from arc
The vertical end wall punishment of groove is cut into main body and insert two parts, and ensures to keep stitching state when main body is assembled with insert.Main body
Arc groove and the through hole for assembling insert are processed using wire cutting, ensure tolerance dimension, ensures that through hole is with insert
Pressing relation.The processing of insert is fairly simple, can directly wire cutting be cut into, shape ensure match with the through hole in main body and be
Pressing relation.By main body and the through hole equating for press fit arrangement insert, the arc groove in main body forms R0 angles with insert side
Type face, the processing of minimum R angle-style tire is completed eventually through assembling.
A kind of minimum R angle-style tire processing method of the present invention efficiently solves the processing problems of smaller R angle-style tire, and script is multiple
Miscellaneous intractable machining state greatly simplifies, and such a mode is proven easy, time saving, saving of labor, material-saving, has saved production
Cost and processing intensity.
