The specific embodiment
Below, for the clutch disc of automatic transmission, at the clutch disc 16(that is provided with a plurality of tooth portion interior week with reference to Fig. 4 (c)) situation be example, the manufacture method of the clutch disc of embodiment is described.
Fig. 1 is the flow chart of manufacture method of the clutch disc 16 of embodiment.In addition, in Fig. 1, each operation (S1～S6) of processing with processing together represents for processing the parts of processing and the parts that obtain as processing the result of processing.
Fig. 2 is that explanation is from the metallic plate 10 of a rectangular shape to the figure that makes the base material 13 of round-ended cylinder shape.In addition, in Fig. 2 (a)～(c), at the downside of the top view of each parts (metallic plate 10, plate-shaped member 11, residual parts 12, base material 13), in the profile (A-A profile) of each parts, indicate in the lump to have emphasized the mark of the thickness of these parts.
In the manufacture method of the clutch disc of embodiment, by the metallic plate 10(of a rectangular shape with reference to Fig. 2) manufacture clutch disc 16(with reference to Fig. 4).
At this, metallic plate 10 consists of the metal material that forms clutch disc 16, have spread all over whole region approximate equality thickness W1(with reference to Fig. 2 (a)).
First, at step S1(with reference to Fig. 1) in, by metallic plate 10 is carried out to circular stamping-out, make conglobate plate-shaped member.Now, together obtain having at central portion the residual parts 12 of the big or small opening 12a mating with plate-shaped member 11 with circular plate-shaped member 11, but these residual parts 12 are not used in the manufacture of later clutch disc 16 and go out of use.
Then,, in step S2, by plate-shaped member 11 is carried out to pull and stretch processing, make the base material 13 of round-ended cylinder shape.
This base material 13 has circular bottom 13a from axially seeing, spread all over the surrounding wall portion 13b that complete cycle surrounds the periphery of bottom 13a, and surrounding wall portion 13b spreads all over complete cycle apart from the height h1 of bottom 13a and forms with equal height.
In addition, the inner diameter D 1 of surrounding wall portion 13b is set as than the inner diameter D a(of the clutch disc 16 finally obtaining with reference to Fig. 4) little (Da > D1).For guaranteeing the formation space of the tooth portion 161 of clutch 16.
Fig. 3 is that explanation is from base material 13 to the figure that makes wide diameter portion 14 and new base material 13A.In Fig. 3 (a)～(c), at the downside of the top view of each parts (base material 13,13 ', wide diameter portion 14, new base material 13A), in the profile (A-A profile) of each parts, be marked with in the lump the mark of the thickness of having emphasized these parts.
At step S3(with reference to Fig. 1) in, the end 13b1 side of the open side of the surrounding wall portion 13b of base material 13 is implemented to expanding, form along with towards distolateral by force, inner diameter D 2 becomes large wide diameter portion 14.
Then, in step S4, be formed with the base material 13 of wide diameter portion 14 ' in, along the horizontal line Z(with respect to bottom 13a level with reference to Fig. 3 (b)) by the basic point of the bending in the basic point 13b2(surrounding wall portion 13b of the wide diameter portion in surrounding wall portion 13b 14) cut off.Thus, be formed with the new base material 13A that the height of the base material 13 of wide diameter portion 14 ' be divided into wide diameter portion 14 and surrounding wall portion 13b reduces.At this, the surrounding wall portion 13b of the base material 13A newly obtaining apart from the height h2 of bottom 13a than the height h1 of the surrounding wall portion 13b of above-mentioned base material 13 low the height ha(of the wide diameter portion 14 that cuts off with reference to Fig. 3 (a)) amount (h1 > h2).
In embodiment, one end of surrounding wall portion 13b (end 13b1) side spreads all over complete cycle and is formed with wide diameter portion 14 to radial outside bending, be formed with the base material that has round-ended cylinder shape 13 of wide diameter portion 14 ' in, rigidity strength ratio wide diameter portion 14 height of wide diameter portion 14 sides of surrounding wall portion 13b (basic point 13b2 side).
Therefore, when the basic point 13b2 of wide diameter portion 14 cuts off surrounding wall portion 13b, can suitably prevent that the stress of effect makes the situation of the wide diameter portion 14 sides distortion of surrounding wall portion 13b owing to cutting off, and the horizontal line Z that can take with bottom 13a level as boundary by wide diameter portion 14 and surrounding wall portion 13b disjunction.
In addition, rigidity strength ratio wide diameter portion 14 height of wide diameter portion 14 sides of surrounding wall portion 13b, thus, during from end on observation, the surrounding wall portion 13b of new base material 13A be shaped as with form wide diameter portion 14 before the identical circle of the surrounding wall portion 13b of base material 13.
At this, wide diameter portion 14 needs only as improving the inclination of the rigidity intensity of surrounding wall portion 13b with respect to the cant angle theta of bottom 13a, in the present embodiment, is roughly set as 45 °.
Fig. 4 is that explanation is from wide diameter portion 14 to the figure that makes clutch disc 16.In addition, in Fig. 4 (a)～(c), the downside at the top view of each parts (wide diameter portion 14, plate-shaped member 15, clutch disc 16) is also marked with in the lump the mark of the thickness of having emphasized these parts in the profile (A-A profile) of each parts.
At step S5(with reference to Fig. 1) in, by the wide diameter portion 14 to obtaining, carry out mold pressing (coining) and make from being axially seen as the plate-shaped member 15 of ring-type in step S4.
At this, in the wide diameter portion 14 obtaining at the step S4 by above-mentioned, interior all 140a sides of the base portion 140 of ring-type and periphery 140b the center line X of wide diameter portion 14 axially on skew, Fig. 4 (a) in the situation that, form periphery 140b side than the shape of the more top side of inner circumferential side 140a.Therefore, in the mold pressing in this step S5, the direction in the periphery 140b lateral view in the base portion 140 of wide diameter portion 14 shown in arrow mark f is crooked, finally forms the plate-shaped member 15 of ring-type.
In embodiment, make base portion 140 distortion of ring-type, until base portion 140 is approximately 90 ° with respect to the cant angle theta 1 of the center line X of wide diameter portion 14, thereby form the plate-shaped member 15 of ring-type, base portion 140 when mold pressing not to the axially compression significantly of center line X.
Therefore, the width W radially 2 of the base portion 150 of the ring-type in plate-shaped member 15 is the slightly large width of width ha radially than the base portion of the ring-type in wide diameter portion 14 140, but interior all 150a of base portion 150 and periphery 150b from end on observation to shape not from interior all 140a of wide diameter portion 14 and the end on observation of periphery 140b to shape be out of shape significantly, remain circular.
In step S6, by the plate-shaped member 15 to ring-type, carry out punching press stamping-out, be formed in the clutch disc that is formed with tooth portion 161 interior week 16 of the base portion 160 of ring-type.Now, interior all 150a sides of plate-shaped member 15 and small part 15a, the 15b of periphery 150b side go out of use as residual parts 17.
At this, in the base portion 150 shown in Fig. 4 (b), usage flag 15a represents the scope of the formation tooth portion 161 in interior all 150a of base portion 150, has omitted the diagram of shape of the tooth portion 161 of final formation.
At this, in above-mentioned step 4, except wide diameter portion 14, obtain the new base material 13A that has round-ended cylinder shape of the height reduction of surrounding wall portion 13b.
This base material 13A in step S7, the height of confirming surrounding wall portion 13b be whether can newly form the height of wide diameter portion 14, be whether can expanding height.
In the situation that be can expanding height, new base material 13A is carried out to expanding, by the wide diameter portion 14 forming by expanding, form new clutch disc 16.
Therefore, the height of surrounding wall portion 13b in new base material be can expanding height during, due to repeatedly carry out expanding (Fig. 1: S3) and cut apart (Fig. 1: S4), so made by initial sheet metal 10 according to the clutch disc 16 of repeatedly carrying out the regulation sheet number that number of times determines of expanding.
Fig. 5 be explanation by the base material that has round-ended cylinder shape 13 forming at first each carry out expanding (Fig. 1: S3) and cut apart (Fig. 1: the new base material 13A obtaining in the time of S4) ..., 13X figure.
At this, in the manufacture method of the clutch disc 16 in embodiment, can obtain each carry out expanding (Fig. 1: S3) and cut apart (Fig. 1: in the time of S4), the base material 13A that has round-ended cylinder shape reducing before the aspect ratio of surrounding wall portion 13b ..., 13X.
Therefore, if carry out repeatedly expanding (Fig. 1: S3) and cut apart (Fig. 1: S4), the height of the surrounding wall portion 13b that has round-ended cylinder parts newly obtaining reach can not implement expanding height hx(with reference to Fig. 5 (d)).
In these cases, the base material 13X that there is the surrounding wall portion 13b of the height hx that can not the carry out expanding (Fig. 1: S7) that goes out of use.
At this, in embodiment, the height of surrounding wall portion 13b that has the base material 13 of round-ended cylinder shape is reduced and makes clutch disc 16, even but the height of surrounding wall portion 13b reduce, also can keep by bottom 13a the rigidity of the lower end side of surrounding wall portion 13b.
Therefore,, in the base material 13X-1 before the height of surrounding wall portion 13b becomes the height hx that can not implement expanding, although the height hx-1 of surrounding wall portion 13b is low, can guarantee by bottom 13a the rigidity intensity of surrounding wall portion 13b.
Therefore,, even above-mentioned base material 13X-1 is carried out to expanding, the shape of surrounding wall portion 13b and wide diameter portion 14 is not significantly avalanche also.In addition, during cutting apart after expanding, even the stress of shearing etc. in surrounding wall portion 13b effect, from the also not significantly avalanche of shape of the wide diameter portion 14 of surrounding wall portion 13b separation.
In the above-described embodiment, for example understand the situation of being manufactured clutch disc 16 by the metallic plate 10 of a rectangular shape, but also can prepare the base material only being formed by surrounding wall portion 13b cylindraceous, by the base material only being formed by this surrounding wall portion 13b cylindraceous, manufacture clutch disc 16.
In addition, also can not prepare the metallic plate 10 of a rectangular shape, and prepare a circular metallic plate (plate-shaped member 11), by this plate-shaped member 11, manufacture clutch disc 16.
As mentioned above, in embodiment, comprise following step: in the base material 13 of surrounding wall portion 13b with tubular, in one end (end 13b1) of the length direction of surrounding wall portion 13b side, form to the wide diameter portion of the wide diameter portion 14 of this end 13b1 hole enlargement and form operation (Fig. 1: S3);
The base material 13 of wide diameter portion 14 ' be divided into segmentation process (Fig. 1: S4) of wide diameter portion 14 and the new base material 13A except wide diameter portion 14 will be formed with;
By the wide diameter portion 14 to being obtained by segmentation process, carry out mold pressing procedure (Fig. 1: S5) that the plate-shaped member 15 of ring-type is made in mold pressing;
By the plate-shaped member 15 to ring-type carry out stamping-out obtain have in interior week tooth portion 161 ring-type clutch disc 16 blank operation (Fig. 1: S6),
Length on the length direction of the surrounding wall portion 13b of the new base material being obtained by segmentation process wide diameter portion form in operation longer than the length (hx) that can not form wide diameter portion 14 during, to the new base material 13A being obtained by segmentation process ..., 13X-1 carries out wide diameter portion and forms operation, segmentation process, stamping procedure, blank operation, make clutch disc 16
If the length on the length direction of the surrounding wall portion 13b of the new base material 13X being obtained by segmentation process for not forming the length (hx) of wide diameter portion 14, is manufactured the clutch disc 16 of the discarded formation of this base material 13X.
If form in this wise, Length Ratio on the length direction of the new base material 13 being obtained by segmentation process can not form the length (hx) of wide diameter portion 14 long during, the base material 13A that use newly obtains ..., 13X-1 repeatedly carries out wide diameter portion and forms operation～blank operation, so can obtain a plurality of clutch disc 16 by a base material 13 of preparing at first.
The base material 13X of the surrounding wall portion 13b that only remains the length (hx) that can not form wide diameter portion 14 in the initial base material 13 of preparing finally goes out of use.Therefore, owing to can reducing the part going out of use in base material 13, so can yield rate manufacture well the clutch disc 16 of ring-type.
In addition, because the plate-shaped member 15 of the ring-type being obtained by base material 13 is made the clutch disc 16 of ring-type, so the intensity of the clutch disc 16 obtaining becomes the high rigidity intensity of clutch disc Kp ' of the ring-type of manufacturing than circular-arc parts P4 is connected.
Therefore the clutch disc of, can yield rate manufacturing well the ring-type with enough intensity.
Particularly, interior all 140a sides of the base portion 140 of ring-type and periphery 140b side are carried out mold pressing by the wide diameter portion 14 of the axial dipole field at center line X, make wide diameter portion 14 distortion, until outside diameter 140b is positioned at the radial outside of internal side diameter 140a, form the plate-shaped member 15 of ring-type.
In the situation that manufacture the plate-shaped member of ring-type to connecting into the punching presses such as wire rod of ring-type, be difficult to control interior week of plate-shaped member of the ring-type obtain and the shape of periphery, so be difficult to stably make the plate-shaped member of the ring-type with the required width radially of the stamping-out of clutch disc.
If form as described above, when mold pressing, due to the axially compression significantly to center line X by the base portion of wide diameter portion 14 140, so interior all 150a of the base portion 150 of the plate-shaped member 15 obtaining and periphery 150b from end on observation to shape from interior all 140a of wide diameter portion 14 and the shape from end on observation of periphery 140b, be not out of shape significantly, be retained as circular.
Therefore, the width W 2 of the base portion 150 of the plate-shaped member 15 obtaining does not change significantly from the width ha of the base portion 140 of wide diameter portion 14, so can stably obtain having the plate-shaped member 15 of the ring-type of the required radial width of stamping-out clutch disc 16.
The base material with the surrounding wall portion 13b of tubular is another distolateral base material that has round-ended cylinder shape 13 being sealed by bottom 13a of surrounding wall portion 13b, before wide diameter portion forms operation, have by the plate-shaped member 11 to circular and carry out the drawing sequence that pull and stretch is formed with the base material 13 of round-ended cylinder shape.
In the manufacture method of the clutch disc 16 of above-mentioned embodiment, while often obtaining new base material 13, the height of surrounding wall portion 13b reduces.
In the situation that base material 13 only consists of the surrounding wall portion 13b of tubular, reduction due to the height along with surrounding wall portion 13b, the rigidity strength decreased of base material 13, even so the length of surrounding wall portion 13b be can shape wide diameter portion 14 length, at the wide diameter portion 14 being obtained by base material 13 and plate-shaped member 15, can produce deviation in shape.
If another distolateral base material that has round-ended cylinder shape being sealed by bottom 13a of base material 13 surrounding wall portion 13b, even if the height of surrounding wall portion 13b reduces, also can be guaranteed by bottom 13a the rigidity intensity of surrounding wall portion 13b, so can suppress the deviation of the shape of the wide diameter portion 14 that obtained by base material 13 and plate-shaped member 15.
Thus, due to can be by base material for the making of clutch disc 16, until surrounding wall portion 13b becomes the length that can not form wide diameter portion 14, so can reduce the part going out of use in base material 13, can yield rate manufacture well the clutch disc 16 of ring-type.
Before drawing sequence, also possess by the metallic plate 10 to rectangular shape and carry out the circular blank operation that stamping-out obtains circular plate-shaped member 11.
In the situation that base material 13 only consists of the surrounding wall portion 13b of ring-type, the part finally going out of use in base material 13 can be suppressed to Min., but the base material 13 only consisting of the surrounding wall portion 13b of ring-type compares with metallic plate 10, purchase cost improves.
By the metallic plate 10 to rectangular shape, carry out the conglobate plate-shaped member 11 of stamping-out system, and by this plate-shaped member 11 is carried out to the base material 13 that pull and stretch is made round-ended cylinder shape, the surrounding of the plate-shaped member 11 in metallic plate 10 (residual parts 12) is not used in the manufacture of clutch disc 16 and goes out of use.
But, even if the purchase cost of metallic plate 10 has been considered the residual parts 12 that go out of use, the circular blank operation newly increasing and the cost of drawing sequence, also lower than the purchase cost of the base material only being formed by the surrounding wall portion 13b of ring-type, so can make more at an easy rate clutch disc 16 as a whole.
At this, in segmentation process, form horizontal line Z(along the bottom 13a level with base material 13 with reference to Fig. 3 (b) by the basic point of the warpage in the basic point 13b2(surrounding wall portion 13b of the wide diameter portion in surrounding wall portion 13b 14) formation cut off.
Be formed with the base material that has round-ended cylinder shape 13 of wide diameter portion 14 ' in, rigidity strength ratio wide diameter portion 14 height of wide diameter portion 14 sides of surrounding wall portion 13b (the basic point 13b2 side of wide diameter portion 14).
Therefore, the basic point 13b2 of the wide diameter portion 14 in surrounding wall portion 13b cuts off surrounding wall portion 13b, can suitably prevent from thus making due to the stress of effect when cutting off the situation of the wide diameter portion 14 side distortion of surrounding wall portion 13b.
Thus, the base material 13A newly obtaining ..., in 13X, this base material 13A ... surrounding wall portion 13b from end on observation to be shaped as with form wide diameter portion 14 before the identical shape (circle) of the surrounding wall portion 13b of base material 13.
Therefore, by the base material 13A newly obtaining ..., wide diameter portion 14 that 13X-1 makes, ring-type plate-shaped member 15 from end on observation to the wide diameter portion 14 made with the base material 13 with by initial of shape, the roughly the same shape of plate-shaped member 15 of ring-type form.Therefore, because the form variations of the wide diameter portion 14 being obtained by a base material 13 and plate-shaped member 15 is few, so can yield rate make well the clutch disc 16 finally obtaining.
In addition, in the above-described embodiment, for example understand the situation of the clutch disc 16 in inner circumferential side with tooth portion 161, but above-mentioned manufacture method is also applicable to have the clutch disc of tooth portion and at inner circumferential side and outer circumferential side, have the manufacture of the clutch disc of tooth portion at outer circumferential side.
In addition, in the above-described embodiment, example has illustrated by the wide diameter portion 14 to being obtained by segmentation process carries out mold pressing, makes the situation of the plate-shaped member 15 of ring-type, but also can make by punching press the plate-shaped member 15 of ring-type.
Above-mentioned in the situation that, by utilize the base portion 140 do not make ring-type to center line X axially significantly the pressure of compression carry out punching press, with the situation of mold pressing similarly, can reduce the form variations of the plate-shaped member 15 finally obtaining.
