In order to solve existing output gear shaft Problems existing in casting process, the invention provides a kind of output gear shaft pendulum and rolling over mould.
Technical scheme of the present invention is: a kind of output gear shaft pendulum rolles over mould, comprise die, yaw punch and connect mould, the described mould that connects is arranged on output gear forging shaft axis body section, and is connected with die by retainingf key, and described die is connected with pressure strip respectively with yaw punch.
Preferably, described yaw punch is connected by retainingf key with between pressure strip.
Preferably, the face that described yaw punch is corresponding with die is cambered surface.
Preferably, the free end of described output gear forging shaft is provided with gag lever post.
Output gear shaft pendulum rolles over a processing technology for mould, comprises the steps:
1. weighing, configures in proportion;
2. make former base, the raw material prepared is put into same set of pressing die, by powder cold moudling under 200-400MPa pressure in above-mentioned steps;
3. put into mould, former base is divided into two parts and is respectively charged into die and connects in mould;
4. pendulum is rolled over and fine and close rotary forging press is put roll over the axis of axle and the angle of pressed compact axis to be adjusted to 1-3 ° to carry out pendulum to pressed compact and rolles over, to put rolling axle rotary speed be 200---300 revs/min, rolling pressure is 200---500MPa, and putting the rolling time is 3-6 second;
5. the output gear shaft forging bar after pendulum rolling is carried out a temper by tempering, and temperature controls at 810-860 DEG C, and the time is 1-1.5 hour, obtains output gear shaft.
Beneficial effect of the present invention: output gear shaft pendulum of the present invention rolles over mould and technique, the time processing achieving output gear shaft is shaping, save man-hour, save material, for next processing is provided convenience, shorten integrated machine process time, improve working (machining) efficiency, and the draw ratio of foundry goods reaches 3.1 > 2.5.
