(summary)
The apparatus main body 1 of present embodiment, except the automobile that is formed with oil circuit, motor that motorcycle is used, such as the oil pump that can also be applicable to have oil circuit, speed changer etc. is formed with the various housings of fluid flowing path etc.The apparatus main body 1 of present embodiment can be the injection-molded article that has utilized the cast article of various metallic material or utilized various metallic material and resin material, the pre-configured piping-member 2 in the inside of this apparatus main body 1, thus make this apparatus main body 1 there is the stream integrally formed with apparatus main body 1.
Below, based on accompanying drawing, an example of mode of execution of the present utility model is described.
In the present embodiment, the example of the part that apparatus main body 1 is shown is motor with oil circuit (below, only be called " engine main body 1a ").Fig. 1 is the stereogram that is formed with the engine main body 1a of oil circuit in inside, and Fig. 2 is the exploded perspective view of piping-member 2.
This engine main body 1a for example forms by cast aluminium alloy.For example dispose the general piping-member formed by steel 2 in the inside of this engine main body 1a.Fig. 1 is the figure of the state of piping-member 2 inside that is cast into engine main body 1a, shows the state that carries out perforation procedure in the end of piping-member 2.Piping-member 2 for example forms cylindrical shape, in order to form oily stream.On this piping-member 2, be provided with this piping-member 2 one and from this piping-member 2 outstanding pipe arrangement holding part 3.These pipe arrangement holding part 3 performances make the function of the stable posture of piping-member 2 when casting.By this pipe arrangement holding part 3 is set, the operation that makes cast form apparatus main body 1 becomes easy.Because easily keep piping-member 2, improve thus the degrees of freedom of the designs such as shape of piping-member 2.Therefore, even the pipe arrangement of complicated shape also can easily be cast into and be formed in apparatus main body 1.
As shown in Figure 2, piping-member 2 for example combines two semimember 2a and forms.Piping-member 2 is cast in engine main body 1a, becomes oily stream 4 in the inside of engine main body 1a thus.
In order to form this semimember 2a, for example tabular component is carried out to punch process and be processed into stero shape.Therefore, can very reasonably form piping-member 2.As a result, can obtain with low cost the apparatus main body 1 of the stream 4 with complicated shape.
With regard to this piping-member 2, as long as, while in the inside of the mold that disposes piping-member 2, injecting the molten metal of constituent apparatus main body 1, the inside that molten metal does not flow into piping-member 2 gets final product.Therefore, also can there is the gap of size to a certain degree on the surface of piping-member 2.
Form the material of each semimember 2a, according to the material that forms engine main body 1a, select suitable material.For example, with regard to fusing point, the high material of fusing point of the material that uses fusing point ratio engine main body 1a to use.Thus, can avoid when casting waits piping-member 2 to be melted the unfavorable condition of the heat fusing of metal.
Like this, in the situation that use dystectic material, can make the wall thickness of semimember 2a thin.As a result, for example plate element is carried out to the processability raising that punch process forms piping-member 2, even the processing of complicated shape also becomes easy.And, because used material tails off, therefore also favourable to the cost aspect.
Each semimember 2a is combined toward each other, and waits and be engaged by riveted joint.Therefore, be formed with the position of half tubular that is used to form stream 4 on semimember 2a, and be formed with lip part 5 at the periphery of semimember 2a.This lip part 5 is positioned toward each other, for example disperse to form along lip part 5 lug boss be engaged with each other on one side and both are carried out to punch process on one side.Fig. 3 means an example in the cross section that draws thus.
In addition, as shown in Figure 2, at lip part 5, with the state stretched out to foreign side, be formed with above-mentioned pipe arrangement holding part 3.Figure 2 illustrates the example that is formed with pipe arrangement holding part 3 at Liang Chu, but can suitably change this quantity according to the size of piping-member 2, length, shape etc.Pipe arrangement holding part 3 can be for example to make lip part 5 extend and form with original thickness, also can adopt in order to ensure intensity the thickness of Thickness Ratio lip part 5 thick, the intensity that can keep reliably pipe arrangement holding part 3 while in a word, thering is the pouring operation of the molten metal after carrying out or injection moulding operation.
Pipe arrangement holding part 3 an only member extension from semimember 2a forms, and also can similarly extend and engage from two semimember 2a to form.Especially, in the situation that extend from two semimember 2a, as shown in Figure 2, easily be formed for the intercommunicating pore 6 of exhaust.
That is, the outer surface of the piping-member 2 of present embodiment is sealed into molten metal and does not invade inner degree.Therefore, when being cast into piping-member 2, the air of the inside of piping-member 2 is expanded, and the air of this expansion according to circumstances inflow engine main body 1a certain position and form hole.Therefore, as shown in Figure 2, be formed with the groove of narrow width in a side of pipe arrangement holding part 3.This groove has the length of the space outerpace of the inner space that is communicated with piping-member 2 and engine main body 1a.Two semimember 2a are engaged with each other, make thus this slot part become intercommunicating pore 6.
In addition, after engine main body 1a solidifies, opening portion that can be by this intercommunicating pore 6 of punching press etc. seals intercommunicating pore 6 and gets final product.
By such intercommunicating pore 6 is set, the molten metal of the mother metal that will form engine main body 1a flow into piping-member 2 around the time, the air expanded in the inside of piping-member 2 is discarded to outside.Therefore, air can not spill to the inside of engine main body 1a, thereby can access the good engine main body 1a that does not produce pore etc.
When finishing casting process, utilize drill bit 7 grades to carry out perforation procedure and form from the outside of engine main body 1a to the processing stream 8 of piping-member 2.Now, decide the position of wanting machining hole with reference to the position etc. of the outstanding pipe arrangement holding part 3 from engine main body 1a.In the stage that is through with the perforation procedure that forms above-mentioned processing stream 8, cut away the pipe arrangement holding part 3 outstanding from engine main body 1a.
As shown in Figure 2, the end of piping-member 2 for example forms truncated cone shape.This is when after the casting that is through with, being used to form the perforation procedure of processing stream 8, if occur that the internal diameter of processing stream 8 is less than the situation of the internal diameter of piping-member 2, the inner face of the processing stream 8 that can make the inner face of the stream 4 of formation in piping-member 2 and form in engine main body 1a middle punch changes continuously, thereby makes flowing smoothly of fluid.Certainly, process the internal diameter of stream 8 if make and equate with the internal diameter with the position that is connected of processing stream 8 in piping-member 2, can prevent inner flow resistance increase.And, if stepped situation occurs, easily at this position, be detained foreign matter, but equate to prevent that by the internal diameter that makes two streams such unfavorable condition from occurring.Therefore, can maintain for a long time the good flowing state of fluid, thereby can access the apparatus main body that reliability is high.
Other mode of execution
(1) when the semimember 2a that will form piping-member 2 is engaged with each other, except above-mentioned riveted joint, also can adopt other the whole bag of tricks.For example, as shown in Figure 4, also can make the size of the lip part 5 of a side be greater than the size of the lip part 5 of opposite side, and the end of a large side is bent each other and engaged.
In addition, in addition, also both sides' lip part 5 can be bonded to each other, or utilize the various welding methods such as spot welding to be engaged.
(2) piping-member 2 and pipe arrangement holding part 3 also can form as shown in Figure 5.That is, only at the two end part of piping-member 2, pipe arrangement holding part 3 is set.And, at least in some pipe arrangement holding parts 3, intercommunicating pore 6 is set.
If this structure, while after pouring operation, being used to form the perforation procedure of processing stream 8, as long as carry out perforation procedure in the position of pipe arrangement holding part 3, so the definite of punch position becomes extremely easy.After having carried out being used to form the perforation procedure of processing stream 8, for example, shown in Fig. 5, at a part of 3a of the remaining pipe arrangement holding part in the both sides of stream opening.Therefore, can easily confirm to process the correct position whether stream 8 is formed at pipe arrangement holding part 3, that is, whether processing stream 8 is formed at correct position with respect to the stream 4 of piping-member.
In addition, in this structure, when being used to form the perforation procedure of processing stream 8, being formed at the intercommunicating pore 6 that the exhaust of pipe arrangement holding part 3 uses and being removed.Therefore, the processing of landfill intercommunicating pore 6 needn't be after the finishing device main body, carried out, thereby manufacture workload and the manufacture cost of apparatus main body can be reduced.
(3) piping-member 2 also can form with the material identical with apparatus main body 1.When operative installations main body 1, although the temperature of apparatus main body 1 changes, now, as long as piping-member 2 and apparatus main body 1 are formed by identical material, both are expanded integratedly or are shunk.Therefore, can not produce the unfavorable condition that causes that because expansivity is different piping-member 2 comes off etc. from apparatus main body 1, thereby can maintain the good state of stream 4.As a result, can access the apparatus main body 1 that reliability is high.In addition, in the situation that this structure is injected molten metal, piping-member 2 is heated until molten metal solidifies, and therefore needs to increase the wall thickness of piping-member 2, not make piping-member 2 fusings.
Apparatus main body of the present utility model, except the automobile that is formed with oil circuit, motor that motorcycle is used, such as the oil pump that can also be applicable to have oil circuit, speed changer etc. is formed with the various housings of fluid flowing path etc.
