Abstract
The invention discloses a die-casting method of a thin-wall oil pipe embedding part oil pan. The method comprises the steps of preheating oil pipes through an oven; moving a wood board at the bottom of a machine stand to reach the middle of a die to prepare for mounting the oil pipe; moving out the heated oil pipes from the oven; keeping the surfaces of the oil pipes free of oil stain; aligning the middle of the oil pipes to two end heads; mounting the #1 oil pipe above and mounting the #2 oil pipe below, wherein the #1 oil pipe and the #2 oil pipe are respectively mounted on corresponding fixing points of the oil pan; examining whether the #1 oil pipe and the #2 oil pipe are clung to a U-shaped clamping slot; connecting the #1 oil pipe and the #2 oil pipe through a plurality of aluminum embedding part blocks which are fixed on the U-shaped clamping slot in the die before closing the die and pouring of a die-casting machine; moving out the oil pan after production; examining whether the oil pipes expose, oil pipe feeders and each pin hole are damaged by buckling, and an interlayer and each corner are burnt and adhered with aluminum. The method has the advantages that the oil pipes can be accurately positioned, aluminum cannot overflow from oil pipe positioning holes, and the oil pipes cannot be flattened and deformed due to non-uniform stressing.
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 using the shell of crankcase seals as oil storage tank.Oil sump is many to be stamped to form by sheet metal, the general employing cast iron that shape is comparatively complicated or aluminium alloy cast molding.Steady oil baffle is equipped with in its inside, and the pasta concussion caused when jolting to avoid diesel engine swashs spatters, and is conducive to the precipitation of impurity of lubricant, side equipped amount dipstick, is used for checking oil mass.In addition, bottom oil sump, lowest part is also equipped with purge cock.
The most of cars seen on the market are all wet sumps, why called after wet sump be due to the crankshaft crank of engine and big end bent axle often rotate a circle all can immerse oil sump lubricating oil in once, play lubrication, running up due to bent axle simultaneously, crank throw immerses in oil sump at a high speed at every turn all can evoke certain oil bloom and mist of oil, bent axle and bearing shell are lubricated, is referred to as splash lubrication.Just had certain requirement to the liquid level of lubricating oil in oil sump like this, if too low, crankshaft crank and big end can not in dip lubrication oil, cause lacking lubrication and smooth crankshaft-and-connecting-rod and bearing shell; If lubricating oil liquid level is too high can cause again the whole immersion of bearing, the rotational resistance of bent axle is increased, finally causes engine performance to decline, lubricating oil easily enters cylinder combustion indoor simultaneously, causes engine burn oil, the problems such as sooting of the spark plug.This lubricating system structure is simple, do not need separately to establish sump, but the gradient of vehicle operation can not be excessive, otherwise can because of oil-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 car.It does not store machine oil in oil sump, says it is do not have oil sump more accurately.All extrude machine oil by metering-orifice one by one to lubricate at friction surfaces of these motions of crankcase.Eliminate the function of the storage machine oil of oil sump due to dry sump engine, so the height of crude oil drain pan just greatly reduces, the height of engine also decreases, and center of gravity reduces the benefit brought and is conducive to manipulation exactly.Topmost advantage is just that of avoiding and those all disadvantageous phenomenons produced due to fierceness driving of wet sump occurs.
But, because the pressure of lubricating oil all will derive from lubricating oil pump.Lubricating oil pump power is then connected by the gear that rotates through of bent axle.Although although also need by lubricating oil pump for camshaft provides force feed in wet sump engine.But this pressure is very little, the power that lubricating oil pump needs is also little.But in the engine of dry sump, the intensity of this force feed needs much larger.And the size of lubricating oil pump is also much larger than the lubricating oil pump of wet sump engine.So now the power of lubricating oil pump needs is also just more more.This is as the engine of engine driven supercharging, and lubricating oil pump needs a part of power consuming engine.Especially high-revolving time, engine speed increases, and the exercise intensity of friction means also just increases, and the machine oil of the lubrication of needs is also many, so just need the pressure that lubricating oil pump provides larger, the consumption for bent axle power also just exacerbates.
Obviously such design is also not suitable for common civilian vehicle engine, because it needs the power losing a part of engine, not only can have influence on Power output, and is unfavorable for improving economy.Therefore dry sump only can be provided on huge discharge or powerful engine, and such as those are for fierceness is driven and on the sport car of giving birth to.Such as Lamborghini is exactly the design adopting dry sump, for it, lubricant effect during the raising limit and the lower center of gravity of acquisition are prior, and the loss of power can make up by improving other aspects such as discharge capacity, as for economy, be then that this vehicle does not need to consider completely.
Thin-walled oil pipe is positioned at oil sump, and Conventional processing methods, when die casting, easily causes oil pipe not to be put into position, and oil pipe locating hole runs aluminium, the defects such as the easy flattening deformation of oil pipe.
Summary of the invention
Object of the present invention, be to overcome above-mentioned limitation, thus provide a kind of pressure casting method of thin-walled oil pipe inserts oil sump, 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 not because of 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, and step is as follows:
A, oil pipe is put into baking box preheating, in baking box, No. 1 oil pipe is put on upper strata, and No. 2 oil pipes are put in lower floor, and in baking box, preheat temperature is set in 150 DEG C, actual preheat temperature between 120 DEG C-150 DEG C, 5 minutes preheating time;
B, die casting machine Qianmen are opened, and move in the middle of mould by board sill plate, do the preparation of installing oil pipe;
C, in baking box, take out the oil pipe after preheating, keep oil pipe surface without greasy dirt, by the middle of oil pipe and two ends alignment, above No. 1 oil pipe is arranged on, below No. 2 oil pipes are arranged on, No. 1 oil pipe and No. 2 oil pipes are arranged on fixing point corresponding to oil sump respectively;
D, installation oil pipe, first check in fixing spot hole whether have charging, then No. 1 large end of oil pipe is aimed at mould No. 1 point insertion, the U-shaped draw-in groove of aligning location, middle part, and No. 1 oil pipe small end inserts mould No. 2 point places; No. 2 large ends of oil pipe are aimed at No. 3 points and are inserted, the U-shaped draw-in groove of location is aimed in middle part, No. 2 oil pipe small ends are aimed at No. 4 points and are inserted, check whether No. 1 oil pipe and No. 2 oil pipes fit with U-shaped draw-in groove, No. 1 oil pipe is connected by some aluminium inserts blocks with No. 2 oil pipes, and aluminium inserts block is fixed on the U-shaped draw-in groove of mould before the perfusion of die casting machine matched moulds;
E, die casting machine matched moulds pour into, and produce product, have produced rear pliers and clamped oil sump running channel, held bottom oil sump with wooden mallet, taken out by oil sump;
F, check whether product has that oil pipe exposes, oil pipe charging and each pin hole buckle wound, water tail loose core locate cold shut, interlayer and position, each angle burn glue aluminium, 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, oil pipe can not because of unbalance stress flattening deformation.
