Description
Technical field
The present invention relates to a kind of pressure casting method of thin-walled oil pipe inserts oil sump.
Background technology
Oil sump is positioned at engine bottom, dismantled and assembled, and shell using crankcase seals as oil storage tank. Oil sump is many by thinSteel plate punched forms, general employing cast iron or aluminium alloy cast molding that shape is comparatively complicated. Steady oil baffle is equipped with in its inside, withThe pasta concussion causing while avoiding diesel engine to jolt swashs spatters, and is conducive to the precipitation of impurity of lubricant, and side equipped amount dipstick, is used forCheck oil mass. In addition, oil sump bottom lowest part is also equipped with purge cock.
Most of cars of seeing are on the market all wet sumps, and why called after wet sump is due to engineCrankshaft crank and big end often rotate a circle and all can immerse in the lubricating oil of oil sump once at bent axle, play lubricated workWith, crank throw is each to be immersed in oil sump and all can evoke certain oil bloom and mist of oil at a high speed, to song because bent axle runs up the whileAxle and bearing shell are lubricated, and are referred to as splash lubrication. To lubricating oil, the liquid level in oil sump has just had certain like thisRequirement, if too low, crankshaft crank and big end can not dip lubrication oil in, cause lacking lubricated and smooth bent axle and companyBar and bearing shell; Can cause again the whole immersion of bearing if lubricating oil liquid level is too high, the rotational resistance of bent axle is increased, finally leadCause engine performance and decline, it is indoor that while lubricating oil easily enters cylinder combustion, causes engine burn oil, sooting of the spark plug etc.Problem. This lubricating system is simple in structure, does not need separately to establish sump, but the gradient of vehicle operation can not be excessive, otherwise can be because ofOil-break, leakage of oil and cause tile kilning scuffing of cylinder bore accident.
Dry sump is used in the engine of a lot of racing cars. It does not store machine oil in oil sump, says so more accuratelyThere is no oil sump. All to extrude machine oil by metering-orifice to be one by one lubricated at the friction surface of these motions of crankcase. ByCancel the function of the storage machine oil of oil sump in dry sump engine, so the height of former oil sump just reduces greatly, the height of engine also decreases, and center of gravity reduces the benefit of bringing and is conducive to exactly manipulation. Topmost advantage is kept away exactlyExempted from occur wet sump those because fierceness is driven all disadvantageous phenomenon producing.
But, because the pressure of lubricating oil all will derive from lubricating oil pump. Lubricating oil pump power is turning by bent axleMove and connect to come by gear. Although although also need to provide pressure by lubricating oil pump for camshaft in wet sump engineHydrodynamic lubrication. But this pressure is very little, the power that lubricating oil pump needs is also little. But at the engine of dry sumpIn, the intensity of this force feed needs much larger. And the size of lubricating oil pump is also than the machine oil of wet sump enginePump is much larger. So the power that now lubricating oil pump needs is also just more more. This as the engine of engine driven supercharging, machine oilPump need to consume a part of power of engine. Especially high-revolving time, engine speed increases, friction meansExercise intensity also just increases, and the lubricated machine oil needing is also many, thus just need lubricating oil pump that larger pressure is provided, for bent axleThe consumption of power has also just aggravated.
Obvious such design is also not suitable for common civilian vehicle engine, because it need to lose a part of enginePower, not only can have influence on power output, and be unfavorable for improving economy. Therefore dry sump only can be provided in large discharge capacityOr on powerful engine, such as those are driven on the sport car of giving birth to for fierceness. For example Lamborghini adopts dry type exactlyThe design of oil sump, for it, the lubricant effect while improving the limit and the lower center of gravity of acquisition are prior, and meritThe loss of rate can make up by improving other aspects such as discharge capacity, as for economy, is that this vehicle does not need to consider completely.
Thin-walled oil pipe is positioned at oil sump, and traditional handicraft method, in the time of die casting, easily causes oil pipe not to be put into position, oil pipeLocating hole runs aluminium, the defects such as the easy flattening deformation of oil pipe.
Summary of the invention
Object of the present invention, is to overcome above-mentioned limitation, thereby a kind of die casting side of thin-walled oil pipe inserts oil sump is providedMethod, its advantage is: make oil pipe be put into position by the locating hole on oil sump, oil pipe locating hole can not run aluminium, oil pipe can be because ofFor unbalance stress flattening deformation.
Object of the present invention is achieved through the following technical solutions: a kind of pressure casting method of thin-walled oil pipe inserts oil sump,Step is as follows:
A, oil pipe is put into baking box preheating, in baking box, oil pipe is put on upper strata No. 1, and oil pipe is put No. 2 in lower floor, pre-hot temperature in baking boxDegree be set in 150 DEG C, actual preheat temperature between 120 DEG C-150 DEG C, 5 minutes preheating time;
Open at B, die casting machine Qianmen, and board sill plate is moved in the middle of mould, does the preparation that oil pipe is installed;
C, in baking box, take out the oil pipe preheating, keep oil pipe surface without greasy dirt, by the middle of oil pipe and two ends align,No. 1 oil pipe is arranged on top, and No. 2 oil pipe is arranged on below, and No. 1 oil pipe and No. 2 oil pipes are arranged on respectively corresponding the consolidating of oil sumpIn fixed point;
D, oil pipe is installed, is first checked in fixing point hole, whether there is charging, then No. 1 large end of oil pipe is aimed to No. 1 point of mouldInsert, the U-shaped draw-in groove of location is aimed in middle part, and No. 1 oil pipe small end inserts No. 2 point places of mould; No. 2 the large end of oil pipe is aimed at No. 3Point inserts, and the U-shaped draw-in groove of location is aimed in middle part, and No. 2 oil pipe small ends are aimed at No. 4 points and inserted, and check No. 1 oil pipe and No. 2 oilWhether pipe fits with U-shaped draw-in groove, and No. 1 oil pipe is connected by some aluminium inserts pieces with No. 2 oil pipes, and aluminium inserts piece is at die casting machine matched mouldsBefore perfusion, be fixed on the U-shaped draw-in groove of mould;
The perfusion of E, die casting machine matched moulds, produces product, has produced to clamp oil sump running channel with pliers afterwards, holds oil with wooden malletDrain pan bottom, takes out oil sump;
F, check whether product has that oil pipe exposes, oil pipe charging and each pin hole buckle wound, water tail loose core cold shut, the interlayer locatedAnd the sticky aluminium of the burn of position, each angle, after inspection, product is stacked on plank.
In sum, the present invention has the following advantages: oil pipe accurate positioning, and oil pipe locating hole can not run aluminium, and oil pipe can notBecause unbalance stress and flattening deformation.
