Description
Technical field
The invention belongs to plant equipment manufacturing technology field, is related to a kind of manufacturing process of engine, particularly sends out
The production technology of valve retainer in motivation.
Background technology
The effect of engine valve is to be responsible for the input air into engine specially and discharge the waste gas after burning.From starting
In machine structure, it is divided into inlet valve and exhaust valve, the effect of inlet valve is drawn air into engine, with fuel mixed combustion；
The effect of exhaust valve is that the waste gas after burning is discharged and radiated.The opening and closing of usual valve is to drive head portion that by valve stem
Do linear reciprocating motion to realize, engine cylinder is covered provided with valve retainer, passes through the cooperation of head portion that and valve retainer
Realize the closure of valve, the frequent opening and closing of valve so that valve retainer will bear the shock loading of extremely high frequency, while also hold
By in-engine high temperature (570~670K of inlet valve, 1050~1200K of exhaust valve), pressure, the gas of gas are still suffered from addition
The active force and transmission component inertia force of door spring, it is poor plus its lubrication, cooling condition, therefore damage is very easy to, in order to carry
The service life of high engine, the requirement to valve retainer is also very high, to have higher intensity, rigidity, heat-resisting and wearability
Can, its processing cost is also higher.
China's patent (notification number：CN104480401A；The day for announcing：2015-04-01) disclose a kind of heat-resisting valve retainer
Manufacture method, its procedure of processing is：(1), the preparation of valve retainer material；(2), the casting of valve retainer；(3), valve seating
The pre-heat treatment of circle；(4), the finishing of valve retainer；(5) casting, is heated to 850-920 DEG C, 2-4h is incubated, using wind
It is cold, it is quickly cooled down；(6), by by step (5) processing after valve retainer be heated to 700-720 DEG C, 250 DEG C etc.
Isothermal is carried out in thermohaline bath, time 1-1.5h, then air cooling；(7), will be slow by the valve retainer after step (6) processing
500-520 DEG C is heated to, after being incubated enough long-times, air cooling of coming out of the stove.
Valve retainer in above-mentioned patent uses casting, and process is more, it is more to feed intake in its technical process, and is not easy
Control, the quality of casting are not sufficiently stable, and percent defective is of a relatively high, and the valve retainer of casting is also possible that stomata, scab, folder
The defects of sand, sand holes.
