The specific embodiment
Below, embodiments of the present invention are described.In addition, the present invention is not limited to following embodiment.
The first embodiment
Utilize Fig. 1 that embedding formed body of the present invention is described.Embedding formed body 1 comprises resin component element 10 and embeds member 11.Embed formed body 1 and refer to resin component element 10 and embed that member 11 forms as one and the member that obtains, no matter form resin component element 10 on member 11 and all can embedding in which way.If be formed with resin component element 10 on embedding member 11, resin component element 10 and embedding member 11 are bonded together with predetermined closing force.If resin component element 10 and embedding member 11 are bonded together in this way, in the situation that embed during formed body 1 is exposed to the environment that has variations in temperature, may move the different crackles that cause resin component element 1 because of the dilation action that embeds member and the dilation of resin component element.As mentioned above, if resin component element 10 is bonded together with embedding member 11, can produce above-mentioned crack problem, become application of the present invention.In addition, as shown in Figure 1, in the present embodiment, the embedding formed body 1 that will form as one in the mode around the resin component element 10 columned embedding members 11 of covering describes as an example.
And, in the thermoplastic resin composition, except containing the thermoplastic resin as essential composition, can also contain the common additives such as hardening agent, antioxidant, stabilizing agent, pigment, nucleator such as inorganic filler.For example, if the compositions such as glass fibre, calcium carbonate, talcum are contained in resin component element 10, easily produce above-mentioned crack problem.But, according to the present invention, even these compositions are contained in resin component element 10, also can suppress above-mentioned crack problem.
Because resin component element 10 engages and gets final product with embedding member 11 in the above described manner, therefore, the shape of resin component element 10 is without particular limitation of the tubular that is shaped as of, the resin component element 10 in present embodiment.Resin component element 10 engages with embedding member 11 at the internal face of tubular.
As described later, owing to bringing into play effect of the present invention by form stress concentration portion 102 near frangible portion 101, therefore, the shape of frangible portion, size, kind etc. without particular limitation of.
In addition, resin component element 10 also can have a plurality of frangible portion 101, and a plurality of frangible portion can be both the frangible portion of identical type, can be also different types of frangible portion.
As described later, in the present invention, bring into play effect of the present invention by form stress concentration portion 102 near frangible portion 101.Therefore, frangible portion 101 is features of the present invention with the relation of stress concentration portion 102.Below, the relation of frangible portion 101 with stress concentration portion 102 described.
So-called " near " refer to the situation of the close together between frangible portion 101 and stress concentration portion 102.At this, so-called " distance between frangible portion 101 and stress concentration portion 102 " refers to that the each point on the frangible portion 101 divides the minimum range that is clipped to stress concentration portion 102.Need to consider like this that the reason of the each point of frangible portion 101 is, the crackle of resin component element 10 is to put as the starting point generation.
Being equivalent to of frangible portion 101 and stress concentration portion 102 " near " separation degree according to thermoplastic resin lipid species, frangible portion kind etc. and correspondingly different.In addition, also correspondingly different according to the purposes that embeds formed body 1.Its reason is, if purposes is different, the stress that results from resin component element 10 is also different.More particularly, its reason is, if the stress that produces is different, the amount that surpasses allowable stress (maximum stress that frangible portion 101 can not ftracture) that puts in the stress of frangible portion 101 is different, therefore, need to be also different by the size that forms the stress that stress concentration portion relaxes.Like this, so-called " near " though according to purposes, the thermoplastic resin that uses etc. and correspondingly different, by doing as follows, can determine the position of stress concentration portion 102.
Near the purpose that forms stress concentration portion 102 frangible portion 101 is, in the time of when the inside at resin component element 10 produces stress, from the outside to resin component element 10 stress application, by making stress concentrate on the stress that stress concentration portion 102 reduces to put on frangible portion 101, thereby prevent the crackle of frangible portion 101.Thereby, the distance that can reduce to put on the stress of frangible portion 101 be equivalent to " near ".
So-called " can reduce to put on the distance of the stress of frangible portion " can try to achieve according to for example following order.At first, utilize the derivation such as existing known common software not to be formed with stress in the embedding formed body 1 of stress concentration portion 102, that result from frangible portion 101.In addition, utilize existing known common software etc., also derive in the lump the maximum stress (being called in this manual allowable stress) that frangible portion 101 can not ftracture.At this, the stress, allowable stress that results from frangible portion 101 is derived according to specific condition (determine specific thermoplastic resin lipid species, embed the condition of the purposes etc. of formed body).That is, produce in the suitable position that has specified counter stress and concentrate section 102 under the state of most parameters of considerable influence, derive above-mentioned stress.
Then, derive in the same way the stress that results from frangible portion 101 in the embedding formed body 1 be formed with stress concentration portion 102.Make frangible portion 101 and stress concentration portion 102 approach to the stress that results from frangible portion 101 be allowable stress following till.That is the position that, can make the stress that results from frangible portion 101 be in the following stress concentration portion of allowable stress be equivalent to " near ".
About shape, the size of stress concentration portion, also need above-mentioned as meeting " near " take the circumstances into consideration to set according to the kind of thermoplastic resin, purposes.That is, according to the difference of the method that forms stress concentration portion 102, stress concentration portion 102 is near frangible portion 101 or away from frangible portion 101.Therefore, the method for formation stress concentration portion 102 exerts an influence to the crackle of resin component element 10, it is therefore preferable that the shape of stress concentration portion 102 is also determined based on the viewpoint that resin component element 10 can not ftracture.Below the method for the shape of determining stress concentration portion 102 is described.In addition, in the following description, use for convenience of description and only the side of columned embedding formed body 1 to describe.
Fig. 2 is the schematic diagram that embeds the front view of formed body 1.In Fig. 2 (a) and Fig. 2 (b), the length on directions stress concentration portion 102, that stress concentration portion 102 is extended is different.
One end of the weld part in the front view of embedding formed body 1 is made as α, the other end is made as β.If form stress concentration portion 102 as shown in Fig. 2 (a), to compare with the situation that forms stress concentration portion 102 as shown in Fig. 2 (b), the maximum from the assigned position of frangible portion 101 to the distance of stress concentration portion 102 diminishes.As shown in Fig. 2 (a), form stress concentration portion 102 by all become near stress concentration portion 102 modes with the optional position in frangible portion 101, easily bring into play thus effect of the present invention.
As mentioned above, determine position, the shape of stress concentration portion based on the viewpoint of the crackle that suppresses frangible portion.In the situation that frangible portion is a little, only consider that the position of stress concentration portion gets final product, still, in the situation that frangible portion is made of line, face, need to form stress concentration portion near the each point in frangible portion.Therefore, in the situation that frangible portion is made of line, face, the shape that also needs to consider frangible portion forms stress concentration portion to prevent the crackle of frangible portion.Specifically, as shown in Figure 1, in the situation that the frangible portion 101 of wire, preferably to form stress concentration portion across this line and along the mode of this line.In the situation that frangible portion is made of face, preferably the mode with the periphery of enveloping surface forms stress concentration portion.This is because if do like this, can suppress leave stress concentration portion and crack at resin component element by the part that makes frangible portion.
Then, concentrate the relation between the intensity of section to describe to the strength and stress of frangible portion.In the situation that embed during formed body is exposed to the environment that has variations in temperature, be the part that easily cracks in frangible portion, stress concentration portion.Its reason is, the intensity of the material of frangible portion self is lower, thereby stress concentration portion is compared with other parts and easily is applied in stress and easily damages.But in most cases, the frangible portion specific stress concentrates section more easily to crack, and the present invention is in the situation that the frangible portion specific stress concentrates section easily to crack is effective.So-called " situation that the frangible portion specific stress concentrates section easily to crack " can try to achieve by utilizing existing known software analysis allowable stress.
The common material that all the time uses can be used in the surface that embeds at least a portion of member 11 in embedding formed body.That is, the material of formation embedding member 11 can be any one in metal, inorganic material, organic material.Specifically, can enumerate the metals such as tapping, cast iron, stainless steel, aluminium, copper, gold, silver, brass, the pottery with thermal conductivity, material with carbon element etc.In addition, being formed with the metal etc. of metallic film on the surface also can be as embedding member 11.As metallic film, can the film that form such as by electroplating processes (wet type electroplating processes, dry type electroplating processes etc.) be shown example.In addition, embed member 11 except the monomer that refers to metal, inorganic material etc., sometimes also refer to comprise the compound of various metals, resin etc.
The material that consist of to embed member 11 can consider such as purposes, consist of resin component element resin material the physical property such as coefficient of thermal expansion and take the circumstances into consideration to select preferred material.
For the manufacture of the forming process that embeds member 11 without particular limitation of, but, in the situation that be for example metal, can utilize the methods such as die casting such as the processing such as machining carried out based on existing known lathe, die casting, injection mo(u)lding, pressure stamping-out to come the embedding member of manufacturing objective shape.
The manufacture method that embeds formed body 1 without particular limitation of, can adopt common method.For example, can list the embedding member is disposed in mould, the thermoplastic resin composition of molten condition is flowed in mould.
Utilize Fig. 3 that effect of the present invention is described.(a) of Fig. 3 is the schematic diagram in the cross section after the MM along Fig. 1 cuts open.(b) of Fig. 3 is the schematic diagram that is not formed with the cross section after cutting open along MM in stress concentration portion 102 situations.Point X is frangible portion 101, and extends along the direction that runs through paper.
As shown in Figure 3, the situation along the direction stress application of hollow arrow indication is described.The length of hollow arrow represents the size of stress.In the situation that do not form the stress concentration portion 102 of the thinner thickness of comparing resin component element with frangible portion, as shown in Fig. 3 (b), frangible portion 101 is applied larger stress.With respect to this, in the situation that be formed with stress concentration portion 102, a part that puts on the stress of frangible portion 101 puts on stress concentration portion 102.Consequently, the stress that puts on frangible portion 101 diminishes.Diminish if put on the stress of frangible portion 101, can suppress or postpone the crackle that produces in frangible portion 101.
In the present embodiment, as shown in Figure 2, be formed with a plurality of stress concentration portions 102 in resin component element 10.If stress concentration portion 102 is present in the direction that stress applies, stress concentration portion 102 can be eliminated the part along the stress on the direction of stress application that puts on frangible portion 101.Thereby if be formed with a plurality of stress concentration portions 102, enough minimizings are from more multidirectional stress.Consequently, due to the stress that can further suppress to put on frangible portion, therefore, can further suppress the crackle of frangible portion.For example, in the present embodiment, owing to being formed with stress concentration portion 102 in the mode across frangible portion 101, therefore, can reduce the stress from the left and right both direction.
In the present embodiment, stress concentration portion 102 forms in the mode across the frangible portion 10 of wire, becomes any point in frangible portion 101 all by the state of stress concentration portion 102 clampings.Therefore, because all there is stress concentration portion 102 in the arbitrary position at the line segment that consists of frangible portion 101, therefore, the stress that puts on arbitrary position of frangible portion 101 is all alleviated.
