[0002]

2. Description of the Related Art In a drip molding provided along a side edge of a roof panel of a vehicle, first and second resin portions are formed in a longitudinal direction along both side edges of a long molded material made of a metal profile. A long composite material is used in which a long molding material is exposed between the first and second resin parts and a bright part different in color from the resin part is formed. In such a long composite material, the width, the cross-sectional shape, and the like of the long molding material, the first and second resin portions, the outer surface side of the bright portion, and the like change in the longitudinal direction in order to enhance decorativeness. Things may be required.

[0003] As a conventional method for producing such a long composite material having a variable cross-sectional shape, the first or second composite material is partially used.
First and second members formed by extrusion molding of the resin part are arranged so that a part thereof overlaps, and the width of the exposed part is changed by changing the width of the overlapping part along the longitudinal direction, and seam welding is performed. (For example, Japanese Patent Application Laid-Open No. 8-282399).

[0004] However, such a long composite material has two problems.
Since various types of members are superimposed on each other to form a composite material, one of the members undergoes local tensile and compressive stresses at the start and end points of the change, easily twisting, making it impossible to obtain a uniform product and wasting material. There is a problem such as there is.

In order to avoid such a point, the strip material is trimmed by a press or the like to form a metal profile having a variable width, and a resin portion is integrated with the metal profile by extrusion or injection molding. A long composite material is also known, but also in this long composite material, there is a problem that material is wasted due to trimming.

[0008] In the present invention, "resin" includes synthetic resins and rubber. Also, "near the boundary between the fixed width part and the enlarged width part"
Means at or near the boundary between the fixed width portion and the enlarged width portion.

The long composite material of the present invention has a structure in which a resin portion is compositely integrated along the longitudinal direction of a long molded material such as a metal deformed material, and an enlarged width portion continuously extends from a fixed width portion. It is a long composite material. The long molded material has a substantially constant cross-sectional shape in the fixed width portion and the width of the visible portion, and is divided into a plurality of partially molded materials in the enlarged width portion and is isolated from each other. The resin part is formed so as to cover the separated part of the formed partial molding material.

Generally, the resin portion is formed along the longitudinal direction so as to cover the isolated portion of the partial molded material. In this case, the side of the long molded material where the resin portion is not formed is formed. It is preferable that a second resin portion is formed along the line to provide decorative edging and cushioning for preventing scratching. Since the enlarged width portion has a width that is larger than the fixed width portion, the width of both the resin portion and the non-covered portion that is not covered by the resin portion of the partially molded material in the enlarged width portion is
There is a case where the width is larger than each width in the fixed width portion, and a case where only one of them is expanded and the other, for example, the uncovered portion has the same width as the width of the fixed width portion.

As the long formed material, if a metallic bright color is desired on a part of the outer surface of the long material, a metal deformed material, particularly a deformed material formed by roll forming a metal plate such as a stainless steel plate or aluminum. Extruded material of alloy is preferred,
If other specifications are desired, it may be made of another material such as an extruded product of a rigid resin having rigidity. Such a long molded material may be partially formed by forming a slit or the like along the longitudinal direction in a portion to be the enlarged width portion to form a partially molded material of the enlarged width portion, or may be partially molded. It is also possible to form a long molded material by partially joining the materials along the longitudinal direction at a fixed width portion. The resin part is preferably formed by injection molding, and the second resin part is preferably formed by extrusion molding.

[0012] Such a long composite material has a structure extending from the end of the fixed width portion corresponding to the center portion so that the enlarged width portion is located at the front portion and / or the rear portion of the vehicle in the case of drip molding. By bending the axis near the boundary between the fixed width section and the enlarged width section (corresponding to the corner of the vehicle), it can be used as a drip molding of the vehicle. , Rear window molding, body side molding, waist molding, or side sunshade (also referred to as side visor). In drip molding, depending on the styling of the vehicle, a combination of the front part and the center part or a combination of the center part and the rear part may be required. May be required for either the front part or the rear part.

[0013] The long composite material has a substantially constant width corresponding to the fixed width portion, and is separated into a plurality of divided molded materials corresponding to the enlarged width portion to separate the long molded material. It is manufactured by forming and integrating a resin portion along the longitudinal direction of the long molded material so as to cover the portion. As shown in the embodiment, the width of the enlarged width portion is not limited to the width gradually increasing along the longitudinal direction, and includes a fixed width that is larger than the width of the fixed width portion.

In the case where a metal profile is used as the long formed material, the metal profile formed in advance by roll forming a metal plate is partially divided along the longitudinal direction and separated in a direction intersecting the longitudinal direction. What formed the molded material can be used. In the case of forming the second resin portion, it is preferable to use a long molding material in which the second resin portion is formed on one side in advance by extrusion molding.

[0015] As a method of forming the resin portion, it is preferable to carry out injection molding by installing a long molding material in an injection mold. In this case, the resin portion is formed by forming the resin portion such that the width of the uncovered portion of the resin portion and / or the partially formed material in the enlarged width portion is larger than the width of the fixed width portion;
In some cases, the width of the resin portion in the enlarged portion is larger than the width of the fixed width portion, and the width of the non-covered portion of the partially formed material is constant through the enlarged portion and the fixed width portion. When used as drip molding, before or after forming the resin part,
Axial bending is performed near the boundary between the fixed width portion and the enlarged width portion.

The long composite material manufactured as described above is used, for example, in the case of the drip molding, by being attached along the side edges of a front pillar, a roof panel, and a rear pillar from the front side of the vehicle. Long composites for other applications are used for each application. Many of them are generally used for decoration and protection of edges, but are not limited thereto.

In the use state, the long composite material has a fixed width portion and an enlarged width portion formed continuously in the longitudinal direction, and the long molded material and the resin portion are integrally integrated through the fixed width portion and the enlarged width portion. Since at least one of the resin portion and the uncovered portion is enlarged in the enlarged width portion than in the fixed width portion, excellent decorativeness can be obtained.

[0018]

According to the long composite material of the present invention, since the partially formed material is covered with the resin portion while being separated from each other in the enlarged width portion, the long composite material is formed despite the fixed width portion and the enlarged width portion. It is possible to manufacture a long composite material having an excellent appearance with little material consumption and a small amount of material consumption.

In this case, since the resin part is formed in a state where the partial molding materials are separated from each other, the resin part can be formed at an accurate position by injection molding or the like, and thereby, the width or the cross-sectional shape on the outer surface side can be formed. Can be accurately changed, and a long composite material of uniform quality can be obtained. By forming the second resin portion, a long molding material having an even more safe and excellent appearance can be obtained.

According to the method for producing a long composite material of the present invention,
A resin portion is formed along the longitudinal direction of the long molded material and integrated so as to cover an isolated portion of the long molded material divided and separated into a plurality of divided molded materials corresponding to the enlarged width portion. Thereby, the long composite material as described above can be efficiently manufactured.

In this case, by forming the resin portion by injection molding, a resin portion having an excellent appearance can be formed. Further, by forming the second resin portion by extrusion molding, it is possible to efficiently produce a long composite material having an even better appearance.

A folded portion 8 is formed at the upper edge of the long molded material 2, and a second resin portion 4 is formed at that portion.
A step portion 9 protruding toward the vehicle is formed at the lower edge of the long molded material 2, and the resin portion 3 is formed so as to be integrated with an additional resin portion 10 formed outside the portion. Have been. The long molded material 2 has a substantially groove-shaped weather strip holding / mounting portion 12 formed through a lower bent portion 11, and is attached to a vehicle body panel 15 by a screw 14 through a mounting hole 13 with a cushion material (not shown) interposed therebetween. It can be attached. In addition, the enlarged width portion 1a of the long molded material 2,
If the strength in use is insufficient in 1c, a plate-like support member 16 is disposed between the partial molded materials 2d and 2e,
It is preferable to provide a plurality of separate support members 16 such as clips with a gap therebetween in the longitudinal direction.

The long composite material 1 in which the resin portion 3 and the second resin portion 4 are integrated with the long molding material 2 has a fixed width portion 1b and an enlarged width portion 1a when used as drip molding.
In the vicinity of each of the boundaries 17a and 17b with the doors 1a and 5b, the doors 5a and 5b have a smaller radius of curvature than the other parts so as to conform to the shapes of the front and rear corners.
It is axially bent to the side. The long composite material 1 is used as a drip molding by being attached to the vehicle body panel 15 along the roof 6d of the vehicle body and the front and rear pillars 6a, 6c.

Hereinafter, a method of manufacturing the long composite material 1 will be described. FIG. 3A is a front view of a deformed material to be a long molded material 2, FIG. 3B is a front view of an intermediate material, and FIGS. 4A and 4B are cross-sectional views of FIG. FIG. The production of the long composite material 1 starts from the deformed material 21 shown in FIG.
An intermediate member 24 having a constant cross-sectional shape shown in FIG. 4B is formed. The deformed member 21 is formed in substantially the same shape as the long molded member 2 having a cross-sectional shape shown in FIG.
1 is formed at a substantially right angle in order to facilitate a manufacturing step to be described later, but is bent into a shape shown in FIG. Such a deformed material 21 is formed by roll-forming a metal strip material such as a stainless steel plate or an aluminum plate, which is to be the long formed material 2, to have a deformed constant cross-sectional shape.

In the line following the roll forming, the shaped member 21 manufactured in this way is formed with the resin portions 3, 4, 1 and 2 at the portions where the resin portion 3, the second resin portion 4, and the additional resin portion 10 are formed.
An adhesive layer 22 for improving the adhesion to the resin layer 0 is formed, and further supplied to an extrusion mold (not shown) to form the second resin portion 4 and the additional resin portion 10 by extrusion molding. Note that the adhesive layer 22 may be formed in a state of a metal strip before the profiled material 21 is formed.
Thereafter, the deformed material 21 is cut to a predetermined size (the length obtained by adding the length required for axis bending to the total length of the drip molding as a finished product) by a press or the like, and the enlarged width portions 1a on both end sides are cut. 1c, a slit is formed in the longitudinal direction with a laser beam, a press die, a saw, etc.
To separate the partially formed materials 2d and 2e. One of the partially formed materials 2d is axially bent near the boundary portions 17a and 17b to be separated, and the intermediate portion 24 is formed by forming the separated portion 2f. It is preferable that the formation range of the length of the separation surface 23 is set to a length including the range where the axis is bent. At this time, the other partial molding material 2e remains linear, and the constant width portion 2b remains the cross-sectional shape of FIG. In addition, the partial molding material 2
As for d and 2e, either of them may be bent axially, or both may be bent. In this embodiment, as can be understood from FIG. 4B, the partially molded material 2e is more than the other partially molded material 2d. Since the rigidity at the time of bending is large, the molded material 2e having high rigidity is left in a straight line, and the partially molded material 2d having small rigidity is bent. Preferably, it is bent.

FIGS. 3B and 4 thus obtained.
The intermediate material 24 shown in FIGS. 5A and 5B is subjected to injection molding as shown in FIGS. FIG. 5 (a)
Is a plan view of an injection mold, (b) is a front view of a long composite material,
FIG. 6 is a sectional view taken along line FF of FIG.

FIGS. 3 (b), 4 (a) and 4 (b) show a cavity 33 formed between the core mold 31 and the cavity mold 32 of the injection mold 30 shown in FIGS.
The intermediate member 24 shown in (1) is installed and the mold is clamped, and a runner 35, two sprues 36, 36, gates 37, 3 from a nozzle touch portion 34 in contact with a nozzle of an injection molding machine (not shown).
Through 7, resin is injected into the cavity 33 from both ends in the longitudinal direction of the intermediate member 24 to form the resin portion 3. When the fluidity of the resin in the cavity is good, a sprue 36a and a gate 37a are provided from only one of the above-mentioned sprues and gates, or at one of the intermediate positions in the longitudinal direction. It is preferable to make the resin flow on both sides, since no weld mark is generated in the resin portion 3. It is preferable to press the outer surface of the second resin portion 4 formed in advance with a cushioning material 38 such as rubber because damage can be prevented. In addition, as the resin used for injection molding, general-purpose plastics such as soft to semi-hard polyvinyl chloride resins, engineering plastics such as modified polyphenylene oxide resin, and polymer alloys of these can be used. Further, a reinforcing material such as glass fiber may be mixed. Injection molding is a method of forming a polyurethane resin by injecting a resin raw material solution containing a mixture of a polyol resin solution and an isocyanate resin solution as a main component, instead of a general thermoplastic synthetic resin injection molding method. Injection molding (RIM) can also be employed. In the RIM method, the viscosity of the mixed solution is smaller than that of a general thermoplastic synthetic resin, so that even a long cavity having a small cross-sectional area can be flowed. Therefore, the RIM method is suitable for molding such a shape.

The long composite material 1 removed from the injection mold 30 after molding has the shape shown in FIG. 5 (b). The GG, HH, and II sectional views in FIG. 5B are almost the same as those in FIGS. 2A, 2B, and 2C, respectively. In order to prevent interference, as shown by 1d in FIG. 2 (c), the lower bent portion 11 has a shape that remains at a right angle. Therefore, after injection molding, the arrow R
By bending in the direction to form the lower bent portion 11 into an acute angle, a long composite material 1 having a cross-sectional shape shown in FIGS. 2A, 2B, and 2C is obtained. Thereafter, axial bending is performed in the directions of arrows P and Q in the vicinity of the boundary portions 17a and 17b, and the surplus portions 26a and 26 are cut by the cut surfaces 25a and 25b as shown in FIG.
By removing b, the long composite material 1 shown in FIG. 1 is obtained. When the same resin material may be used for each resin part in terms of function, the second resin part 4 and the additional resin part 10 are formed simultaneously with the injection molding of the resin part 3 instead of the extrusion molding. In this case, the extrusion molding step can be omitted.

FIG. 7 shows a manufacturing method according to another embodiment.
7A is a front view of the intermediate member, and FIG. 7B is an enlarged view of a part near a boundary 17b in FIG. 7A. In this embodiment,
In the state of the intermediate member 24 shown in FIG. 3B, the resin member 3 is formed by performing bending in advance and then performing injection molding. When axial bending is performed in the state of the intermediate material 24, the partially formed material 2
When bending is performed between d and 2e so as to allow displacement in the longitudinal direction, deviations d ₁ and d ₂ occur between the ends. Note the width W ₂ of the fixed-width portion 1b during the bending axis is divided portion molding material 2d, 2
e, and the tensile stress generated in the compressive stress and the outer generated in the radius of curvature inside during bending axis is divided into each of the molding material, the stress and strain that occurs in comparison with the case of bending the ones integral width W ₂ Is reduced. As a result, the axial bending process is facilitated, and the distortion generated in this portion is reduced, and the discoloration or the like accompanying the generation of the distortion is reduced. .
Also, if the axial bending is performed after the resin portion 3 is formed on the linear intermediate member 24 by injection molding, tensile and compressive stresses and strains are generated by the deviation, but the injection molding is performed after the axial bending of the intermediate member 24. When this is done, no stress associated with the axial bending is generated in the resin portion 3, and the long composite material 1 with little deformation after the resin portion is formed can be obtained. Cutting at the cutting positions 25a and 25b of the terminal may be performed before or after injection molding. In the above-mentioned axial bending, it is preferable to perform processing of the enlarged width portions 1a and 1c (isolation of the partially formed materials 2d and 2e) simultaneously with the axial bending.

FIGS. 8 and 9 show embodiments in which the separation surface is changed. FIG. 8A is a front view of a deformed material, and FIG. 8B is a front view of a long composite material. In FIG. 8, the deformed material 2
1 so that the width of one of the partially formed materials 2d gradually increases toward the ends at the portions that become the enlarged width portions 1a and 1c on both end sides of the first portion 1 and the width of the other partially formed material 2c decreases. By forming the resin portion 3 having a constant width while forming a slope on the separation surface 23 to be formed, a divergent enlarged width portion is formed in the non-covering portion 7 of the long molded material 2 at the separation portions 2a and 2c. I have. The resin portion 3 has a constant width portion 3 even in the coating portions 3a and 3c.
It has the same width as b. In FIG. 9, the separation surface 23 is inclined in the same manner as in FIG. 8, and the width of the resin portion 3 is also changed.
In FIGS. 2A and 2C, a divergent enlarged width portion is formed, and also in the resin portion 3, a divergent enlarged width portion is formed in the covering portions 3a and 3c.

FIG. 10 shows still another embodiment,
(A) is a front view of a deformed material, (b) is a front view of an intermediate material,
(C) is a front view of the long composite material. In this embodiment, the long molded material 2 is laser-welded or spot-welded at the welded portion 27 by abutting or partially overlapping the widthwise ends of the partial molded materials 2d and 2e as separate members in the fixed width portion 2b. It is partially joined along the longitudinal direction by welding or seam welding to be integrated. The partially formed materials 2d and 2e are each formed into a deformed cross section by roll forming in advance, and the adhesive layer 2 is formed.
The one having the second and second resin portions 4 and the additional resin portion 10 formed thereon are welded. The partially formed materials 2d and 2e are integrated by welding at the welded portion 27 to form a fixed width portion 2b, and both end portions are not joined and remain as separated portions 2a and 2c.
In this state, the separating parts 2a and 2c are bent along the axis as shown in FIG.
The long composite material 1 shown in FIG. Thereafter, the axial bending and the surplus portion are cut at the boundary to obtain a long composite material similar to that of FIG.
Also in this case, the resin portion 3 may be formed by performing injection molding after bending the axis at the boundary portion of the long material 1.

The long composite material shown in FIG.
Is formed of a combination of the partial molding materials 2d and 2e as separate members, so that a material suitable for the function required for each of the partial molding materials can be selected and used. For example, partially molded material
If d is a stainless steel plate exhibiting a metallic bright color, and 2e is a galvanized steel plate or the like, the material cost can be reduced as compared with a stainless steel plate integrated. Even if the same material is used, it is possible to increase the plate thickness of the partially formed material 2e which substantially takes on the mounting strength of the product, and use a thinner material for the other 2d. Furthermore, the partial molding materials 2d and 2e as separate members
May be joined after bending in advance. In the above embodiments, the drip molding has been described, so that the axial bending is indispensable. However, when this long composite material is used as a body side molding or a waist molding, the axial bending is not necessarily required.
