The processing technology of described back axle circular cone driven gear specifically comprises the steps:
(1) Mold Making: A, carry out according to the technical parameter of back axle circular cone driven gear mould design and and carry out the making of mould graphics; B, on numerical control machining center equipment, produce base mould, finishing die, punching edger, straightening die, turning profile of tooth pitch circle frock;
(2) forge: after A, raw material blanking with intermediate frequency heating to 1000-1100 DEG C; B, base mould is placed on electric screw press, the material after heating is put into base mould and carries out base; On another electric screw press, precision forging is carried out to reaching designing requirement with finishing die after C, base complete; On punch press, carry out punching trimming by cutting burrs with punching edger after D, shaping, now product temperature is 840-860 DEG C; E, carry out correcting thus the technical requirement reached needed for the form of gear tooth with straightening die on hydraulic press;
(3) turnery processing: A, on 6140 lathes by profile of tooth pitch circle frock, with the pitch circle clamping tooth base car endoporus of profile of tooth and end face; B, with the endoporus after turning and end face for control vehicle face back cone, counterbore, be divided into rough turn processing and finish turning processing to reach product design requirement.
As the further scheme of the present invention: the model of the electric screw press used during base is EP-630T.
As the further scheme of the present invention: the model of the electric screw press used during precision forging is EP-1600T.
As the further scheme of the present invention: the punch press used during punching trimming is 125t punch press.
As the present invention's further scheme: the model of the hydraulic press that timing uses is Y32-2000T
Compared with prior art, the invention has the beneficial effects as follows:
The present invention by form of gear tooth forging and molding by finish forge, is made raw material cutting stock weight reduce 8.92% than original technique, improves utilization rate of raw materials; Because finish forge profile of tooth reaches product service precision, so that postorder is processed without the need to carrying out profile of tooth, decrease the input of Gleason curved tooth machine and tooth Profile Machining operation, avoid profile of tooth to cut finish draw thus keep metallic fiber, improve the quality of products, thus reduce costs, enhance productivity.
