DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molding used as an exterior material of an automobile, and a method and an apparatus for producing the same. More particularly, the present invention relates to a roof side molding provided along a roof side of a vehicle body, a front pillar, and A windshield side mower portion disposed along at least one of the rear pillars, and an automobile molding of a type extruded as a long and integral unit so as to be continuous with each other; and a method for manufacturing the same. It relates to a manufacturing device.

[0002]

2. Description of the Related Art As this kind of automobile mall, for example, one described in Japanese Patent Application Laid-Open No. 10-86766 is known.

[0003] In this conventional technique, a front windshield side molding section and a roof side section are arranged along the front pillar to cover a gap between the front windshield glass and the front pillar. And a roof side molding portion disposed along the line is integrally molded by a known variable cross-section extrusion method as a long integrated body while permitting the required cross-sectional shapes to be different from each other.

As a modified example of such a molding structure, for example, as disclosed in Japanese Patent Application Laid-Open No. 9-24778, in addition to the front windshield side molding part and the roof side molding part, a rear side molding part is provided. In some cases, the rear windshield side molding portion disposed along the rear pillar to conceal the gap between the rear windshield glass and the rear pillar is also integrated.

[0005]

In the above-described conventional automobile molding, since the molding is extruded as one piece in the longitudinal direction while changing the cross-sectional shape of each part, the window on the front side is formed. Between the shield side molding and the roof side molding, and between the roof side molding and the rear windshield side molding, although not necessarily required for molding the vehicle body itself, It is inevitable that a cross-sectionally changing portion, which is a gradually changing portion whose cross-sectional shape continuously changes from the cross-sectional shape to the other cross-sectional shape, is formed by a front pillar, a roof portion, and the like. And the corner formed by the roof and the rear pillar.

Although it is desirable that the length of the cross section is desirably as short as possible (that is, the cross section is rapidly changed from one cross section to the other cross section). In addition, as a special feature of the construction method, its length must be increased to some extent,
As a result, there is a portion where the shape of the molding does not faithfully follow the shape of the body panel side. For example, when the molding is mounted on the vehicle, a partial lifting or twisting of the molding is likely to occur, which deteriorates the suitability of the molding as a vehicle.

Further, when it is necessary to make the above-mentioned cross-sectionally deformed portion faithfully follow, for example, the convex shape on the body panel side, it is necessary to perform notch processing on a part of the molding as post-processing, which increases the number of processing steps. Is not preferred.

Further, when the length of the cross-sectionally deformed portion is extremely reduced, the cross-sectional shape of the molding to be extruded cannot follow the change in the shape of the die on the extruder side, and the shape stability becomes extremely poor. For example, deformation or waving phenomenon occurs on the outer surface of the molding, and the appearance quality of the molding itself is greatly reduced, which is not preferable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and a roof side molding part, a front windshield side molding part, or a rear side windshield side molding part having different cross-sectional shapes from each other is elongated. While assuming that the mall is continuous in the direction,
An object of the present invention is to provide an automobile molding with improved vehicle compatibility and a method of manufacturing the same.

[0010]

According to the first aspect of the present invention, a roof side molding portion disposed along a roof side portion of a vehicle body and at least one of a front pillar and a rear pillar are provided. Along with the roof side molding part, a windshield side molding part having a different cross-sectional shape from the roof side molding part is assumed to be an automobile molding extruded as an integral unit so as to be continuous with each other in the longitudinal direction. A notch-shaped corner molding conforming to the shape of the corner portion between the roof side molding portion and the windshield side molding portion and corresponding to the corner portion formed by the roof portion and the pillar portion of the vehicle body. It is characterized in that the part is formed integrally.

[0011] Further, the invention according to claim 2 is based on claim 1.
On the premise of the invention described in the above, the corner molding portion is provided with fixing means for fixing the portion to the roof portion, for example, a resin or metal molded separately in advance In addition to the case where the clips are integrated by an insert molding method, the case where a double-sided adhesive tape or the like is attached and fixed corresponds to this.

In the automobile molding to which the invention of claim 1 is applied, a roof side molding part, a front side windshield side molding part and a rear side windshield side molding part are integrated. In addition to the above-mentioned type, the roof side molding and the windshield side molding on the front side or the windshield side molding on the rear side are integrally formed. The windshield side moldings on the front side and the windshield side moldings on the rear side may be of a type whose cross-sectional shape changes continuously in the longitudinal direction thereof.

Therefore, according to the first and second aspects of the present invention, the corner molding portion interposed between the roof side molding portion and the windshield side molding portion conforms to the shape of the vehicle body side corner portion. By forming the corner molding portion into a notch shape, the adaptability of the corner molding to the vehicle body itself is improved.

At the same time, by providing a fixing means such as a clip at the corner molding portion, the corner molding portion and thus the molding itself can be more securely positioned and fixed to the vehicle body, which is more effective in preventing the molding from floating. It will be.

According to a third aspect of the present invention, there is provided a method for manufacturing a molding for an automobile according to the first aspect, wherein the roof side molding, the corner molding, and the windshield side molding are continuous with each other. In synchronization with the extrusion of the long intermediate molded body, the corner molding part and the corner molding part cutting cutter immediately after the extrusion molding in the intermediate molded body and the longitudinal direction of the intermediate molded body and the longitudinal direction thereof In this case, the corner molding is formed into a notch by locally moving and relatively moving in the directions orthogonal to each other.

The cutter may have any function as long as it can cut off a part of the corner molding, and any cutter such as a wire or a blade can be used. In particular, in the case of a wire-shaped cutter, it is preferable to give a rotational motion in order to reduce the shearing force at the time of cutting.

As the method of extrusion molding the above-mentioned intermediate molded body, there is a method of extruding an intermediate molded body whose cross-sectional shape changes in the longitudinal direction by changing the shape of the extrusion opening of the die of the extruder itself. This includes a case where a part of the intermediate molded body is cut out immediately after the extrusion molding with a cutter or the like after the extrusion molding is once performed with a constant cross-sectional shape.

Therefore, according to the third aspect of the present invention, when the cutter is positively moved in two directions in synchronization with the extrusion operation of the intermediate molded body, a part of the corner molding is cut off to form a notch. It will be. This means that a sudden change in cross section can be provided within a very short range in the longitudinal direction of the mall, and as a result, an automobile molding excellent in vehicle compatibility can be easily manufactured.

According to a fourth aspect of the present invention, there is provided an apparatus for manufacturing a molding for an automobile according to the first aspect, wherein an extruder for extruding the molding itself is provided on the extrusion side of the die with a die.

First slide driving means for causing
And a second slide drive unit for sliding the cutter in a direction perpendicular to the extrusion direction.

The invention described in claim 5 is the same as the invention in claim 4.
On the premise of the invention described in the above, the cutting unit slides the cutter at least in the extrusion direction in synchronization with the extrusion molding operation of the molding from the die, so that the relative movement speed between the molding and the cutter is increased. It is characterized by being able to positively control the variable.

Therefore, in the invention according to claim 4,
The manufacturing method of claim 3 described above is substantially realized as it is with this device configuration, and by appropriately controlling the movement and stopping of the cutter in two directions and the speed of the movement, the molding extrusion molding operation can be performed. Synchronously, the corner molding part can be partially cut out to give a sudden change in cross section.

In particular, according to the fifth aspect of the present invention, if the cutter is moved in the same direction as the molding extrusion direction in synchronization with the molding extrusion operation, the relative movement speed between the two can be reduced to zero. If the cutter is moved in the direction opposite to the molding extrusion direction, the relative movement speed of both can be increased at a stretch, for example, if necessary, after setting the relative movement speed in the extrusion direction of the molding and the cutter to zero If the cutter is moved in the direction perpendicular to the extrusion direction, a sharp cross-sectional change can be given to the cut surface substantially perpendicular to the longitudinal direction of the molding.

[0023]

According to the first aspect of the present invention, the corner molding is formed into a cutout shape so as to give a sudden cross-sectional change to the corner molding which is to be formed integrally with the so-called general part of the molding. This allows the corner molding, which previously lacked vehicle compatibility, to be able to faithfully follow the shape of the vehicle-side corners, greatly improving vehicle compatibility, and in particular, partially improving the mall. This has the effect of preventing the occurrence of excessive lifting and twisting, etc., and contributing greatly to the improvement of the vehicle appearance quality.

In particular, when the fixing means is provided in the corner molding portion as in the second aspect of the invention, the fixing holding force of the molding on the vehicle body panel is greatly improved, and the adaptability to the vehicle is further improved. effective.

According to the third aspect of the present invention, the corner molding portion is formed in a notch shape in parallel with the extrusion molding of the molding itself, so that a sharp cross-sectional change can be given. Notch processing, which had to be performed as it was, can be performed substantially within the extrusion process, so that the number of steps can be reduced and the cross-sectionally changed shape portion does not become extremely long unlike the conventional one There is an effect that a molding excellent in vehicle compatibility as in the inventions of claims 1 and 2 can be easily and stably formed.

According to the invention set forth in claim 4, according to claim 3,
Can be realized as it is, the number of molding steps can be reduced in the same manner as in the invention of claim 3, and a molding excellent in vehicle compatibility can be easily and stably formed. There is an effect that it can be molded.

In particular, according to the fifth aspect of the invention, since the relative movement speed between the molding and the cutter can be positively variably controlled, the shape of the notch for giving a change in cross section is different. Even flexible shapes can be flexibly handled, and the versatility of the device is high.

On the other hand, in the roof side molding 1B, as shown in FIGS. 3 and 4, a molding body 9 having a head 8 and a pair of left and right lips 10, 11 and the like have the same shape as the windshield side molding 1A. Although it is common, it differs from the windshield side molding 1A side in that the leg 12 as the lower half of the molding main body 9 is substantially cut away. Then, the roof side molding portion 1B is press-fitted into a roof side groove 5 having a wider bottom portion, and both lips 10, 11 are pressed against the inner wall of the roof side groove 5, as shown in FIG. The head 9 is substantially pressed against the upper edge of the roof side groove 5 so as to close the roof side groove 5.

The windshield side molding section 1A and the roof side molding section 1B having different cross-sectional shapes from each other follow the notch-shaped corner molding section 1C which closely follows and conforms to the vehicle body side shape. Interconnected.

The molding 1 including the windshield side molding 1A and the roof side molding 1B in addition to the corner molding 1C has a sectional shape in the longitudinal direction as shown in FIG. A part of the corner molding part 1C which is extruded as a single continuous string-shaped intermediate molded body W which changes but is located between the windshield side molding part 1A and the roof side molding part 1B. Is cut off locally at the time of extrusion molding to form a cutout portion 15, and the corner molding portion 1C itself has a cutout shape. Then, for example, a double-sided adhesive tape 16 is adhered to the corner molding portion 1C after molding as fixing means.

Here, as a variable cross-section extrusion method for extruding the molding 1 of the present embodiment, for example, a shielding plate is disposed at the extrusion opening of the extrusion die, and the shielding plate is placed in parallel with the extrusion operation. In addition to the method of extruding a molding 1 having a different cross-sectional shape in the longitudinal direction by changing the shape of the extrusion port itself by moving, and immediately extruding an intermediate molded body W having a uniform cross-sectional shape from the extrusion port, A method of cutting and removing a part of the intermediate molded body W with a predetermined cutter and extruding the molding 1 having a different cross-sectional shape in the longitudinal direction.

The corner molding 1C, which is located in the middle between the windshield side molding 1A and the roof side molding 1B, has a bent portion extending from the roof 3 to the upper end of the front pillar 2 as shown in FIG. Since the notch 15 faithfully follows the bent shape, the double-sided adhesive tape 16 on the corner molding portion 1C side is adhered to the step portion 17 on the roof 3 side so that it can be firmly fixed. Will be fixed to.

On the other hand, another windshield upper molding 7, which is to be disposed on the upper edge of the windshield 4, as shown in FIG. Thereby, the appearance of the connecting portion between the corner molding portion 1C and the windshield upper molding 7 is also improved.

FIGS. 6 and 7 show the structure of the main part of an extrusion molding line centered on an extruder for extruding the molding 1.

As shown in the figure, a pair of extruder bodies 22 and 23 are provided to simultaneously supply different materials to a single extrusion die 21 to form a so-called composite extrusion form. At the same time, an extrusion opening 24 is formed in the base 21 so as to conform to the cross-sectional shape of the windshield side molding 1A. As a result, a long intermediate molded body W having a uniform sectional shape equal to the sectional shape of the windshield side molding 1A is continuously extruded from the extrusion port 24.

A cutting unit 25 is disposed in the vicinity of the base 21 and downstream of the extrusion unit in the extrusion direction, and further downstream of the cutting unit 25 is a water tank for cooling the extruded molding 1. 26 are arranged.

The cutting unit 25 cuts off a part of the intermediate molded body W extruded from the extrusion port 24 in parallel with the extrusion operation from the extrusion port 24 to give a sectional shape change in the longitudinal direction of the molding. And has a degree of freedom of sliding in two orthogonal axes.

More specifically, for example, a wire-shaped cutter 27 disposed close to the extrusion port 24 of the base 21 is supported at both ends by a frame 28 so as to cross the extrusion port 24 shape. The frame 28 is fixedly supported by a slider 29, and the slider 29 is mounted on a table 30 so as to be slidable in the pushing direction. As a first slide driving means, a direct-acting type forward / backward moving actuator 31 such as a fluid pressure cylinder is provided on the table 30, and its output rod 32 is connected to the slider 29. By the operation of the actuator 31, the cutter 27 is moved to the slider 29.
And slides on the table 30 in the pushing direction.

On the other hand, the table 30 is connected and supported as a second slide driving means by an output rod 34 of a direct-acting type lifting actuator 33 disposed below the table, and the cutter 30 is operated by the operation of the lifting actuator 33. 27 is displaced in the vertical direction (the direction orthogonal to the pushing direction) together with the table 30.

Thus, the cutter 27 can be slid independently or interlocked with each other in the molding extrusion direction and the vertical direction perpendicular thereto in synchronization with the molding extrusion operation. That is, the cutter 27 is synchronized with the operation of pushing out the intermediate molded body W from the extrusion opening 24.
If the cutter 27 is slid to the downstream side in the extrusion direction while adjusting the slide speed, the relative moving speed between the intermediate molded body W and the cutter 27 can be made substantially zero, while the cutter 27 is pushed out. If they are slid toward the upstream side in the direction, the relative movement speed between the two can be increased at a stretch.

Accordingly, in the molding extrusion molding line configured as described above, the intermediate molded body W is formed from the extrusion port 24 with a uniform cross-sectional shape corresponding to the cross-sectional shape of the windshield side molding portion 1A in the molding 1 shown in FIG. While extruding, while simultaneously measuring the actual extrusion molding length, the cutter 27 is slid in two directions, the extrusion direction and the up-down direction, thereby forming the molding 1 shown in FIG. Windshield side molding 1A and roof side molding 1B
It is possible to form the moldings 1 having different cross-sectional shapes from each other and the corner molding portion 1C located therebetween.

If the cutter 27 is heated or given a rotational motion or vibration as required, it is effective in reducing the shear resistance of the cutter 27 at the time of cutting and preventing the molding 1 from being deformed. .

More specifically, when the roof side molding 1B of the molding 1 shown in FIG. 4 is formed, the wire-shaped cutter 27 is attached to the base 21 as shown in FIG.
And the intermediate molding W having a uniform cross-sectional shape, that is, the cross section of the windshield side molding 1A from the extrusion port 24 in this state. An intermediate molded body W having a shape equal to the shape is extruded. Thereby, the portion corresponding to the leg portion 12 of the windshield side molding portion 1A of the uncured intermediate molded body W immediately after the extrusion molding is continuously cut by the cutter 27 along the cutting line Q, and the uniform cross-sectional shape is obtained. Is extruded. The part cut off by the cutter 27 is the water tank 26 shown in FIG.
Is peeled off before passing through, and the remaining product-shaped portion is cooled by passing through the water tank 26 to promote its hardening.

As shown in FIG. 7A, guide rollers 35 and 36 slidable in the extrusion direction are provided together with the cutter 27, and the intermediate molded body W immediately after being extruded is provided to the cutter 27. When the upper and lower positions of the part to be cut are guided by the guide rollers 35 and 36, it becomes more effective in preventing unnecessary deformation of the molding 1 due to the cutting action of the cutter 27.

When extruding the notch-shaped corner molding 1C following the extrusion molding of the roof side molding 1B, the cutter 27 is extruded together with the guide rollers 35 and 36 as shown in FIG. The cutter 27 is raised by a predetermined amount while the relative movement speed with respect to the intermediate molded body W is reduced by sliding at a predetermined speed to the downstream side in the direction, and the vertical wall portion 15a of the notch 15 is cut and formed.

When the depth of the vertical wall portion 15a reaches a predetermined depth by raising the cutter 27 by a predetermined amount, the cutter 27 is fixed at that position as shown in FIG. Alternatively, it is moved toward the upstream side in the extrusion direction together with the guide rollers 35 and 36, and the bottom wall 15b of the cutout 15 is cut and formed.

When the length of the bottom wall 15b of the cutout 15 becomes a predetermined length, the cutter 27 is moved together with the guide rollers 35 and 36 to the downstream side in the extrusion direction as shown in FIG. The cutter 27 is lowered by a predetermined amount while sliding at a predetermined speed to lower the relative moving speed with respect to the intermediate molded body W, and the other vertical wall portion 15c of the cutout portion 15 is cut and formed. As a result, the cutter 27 retreats from the cross-sectional area of the intermediate formed body W, and the notch 15 including the vertical wall portion 15a, the bottom wall portion 15b, and the vertical wall portion 15c forms an abrupt cross section in the intermediate formed body W. A change is given, and as a result, a notch-shaped corner molding 1C is formed continuously with the roof side molding 1B.

Further, in order to form the windshield side molding 1A following the corner molding 1C, the cutter 27 is held at a position retracted from the sectional area of the intermediate molded body W as shown in FIG. When the intermediate molded body W is extruded in this state, as described above, while the initial sectional shape of the intermediate molded body W itself matches the sectional shape of the windshield side molding 1A, the cutter 27
Does not take part in the partial cutting of the intermediate molded body W at all, so that the windshield side molding 1A
Is extruded as having a uniform cross-sectional shape.

By repeating the steps (A) to (D) of FIG. 7, the molding 1 described above is continuously extruded. In addition, the notch-shaped corner molding 1C of the molded molding 1, that is, the notch 15
As shown in FIG. 4, for example, a double-sided adhesive tape 16 is attached as a fixing means in a later step.

Here, in the example of the extrusion molding line, as shown in FIG. 7A, a part of the intermediate molded body W is cut off by fixing and holding the cutter 27 at a predetermined position to form a uniform sectional shape. Although the roof side molding 1B is formed, in the case of a die having a structure in which the shape of the extrusion port 24 itself can be changed by a shielding plate or the like, the step of FIG. Only the portions corresponding to the cutouts 15 need to be cut off only in the steps of FIGS.

FIG. 8 and subsequent figures show a second embodiment of the present invention. In particular, in addition to the sectional shape of the molding 41 itself, the roof side groove 42 of the roof side has the roof side flange 6. This is different from that of the first embodiment.

As shown in FIGS. 8, 9 and 10, the molding 41 to which the present embodiment is applied is a bonding type windshield (front windshield glass) 4.
A front side windshield side molding 41A having a uniform cross-section and disposed along the front pillar 2 to fill a gap between the side edge of the front pillar 2 and the vertical wall 2a of the front pillar 2; In addition to the roof side molding portion 41B having the same cross-sectional shape and arranged to be engaged with the roof side groove 42 of the roof side portion, a portion that bends from the upper end of the front pillar 2 to the roof 3 Windshield side molding part 41
A corner molding 41C is provided between A and the roof side molding 41B, and another is provided between the upper edge of the windshield 4 and the front edge of the roof 3 as shown in FIG. A windshield upper molding 43 is provided, and a terminal portion of the windshield upper molding 43 is the corner molding portion 41C.
Is connected to the mall 41 in the same manner as in the first embodiment.

On the other hand, in the present embodiment, as in the prior art, a so-called gradually changing portion that continuously changes from one cross-sectional shape of the windshield side molding portion 41A and the roof side molding portion 41B to the other cross-sectional shape. The first embodiment is based on the premise that the cross-section changing shape portion 44 is generated, and the notch portion 45 is formed in the cross-section changing shape portion 44 so as to be effectively used as the corner molding portion 41C. Is different from

The above-mentioned windshield side molding section 41
8A and 8A, as shown in FIGS. 8 and 10, a hollow molding body 49 in which a relatively flat head 48 is integrally formed, and upper and lower lips 50 and 51, a panel lip 52 and an auxiliary lip. 53, etc., and the upper and lower lips 50, 5
1, the front glass 4 is sandwiched, and the panel lip 52 and the auxiliary lip 53 are respectively pressed against the front pillar 2 which is a vehicle body panel. At the same time, a drip groove for collecting rainwater is provided between the upper side lip 50 and the head 48 which elastically contacts the windshield 4 in order to prevent rainwater or the like from flowing from the windshield 4 side to the vehicle body side. 54 are formed.

On the other hand, in the roof side molding 41B,
As shown in FIGS. 9 and 10, the molding body 4 including the head 48
9, the upper lip 50, the panel lip 52, and the auxiliary lip 53 have the same shape as the windshield side molding portion 41A, but the lower lip 51
Is different from the windshield side molding portion 41A side in that the lower half of the molding body 49 including is substantially cut off. In the roof side molding 41B, as shown in the figure, the roof side flange 6 is engaged with the center gap 55, while the panel lip 52 and the auxiliary lip 53, in addition to the upper lip 50, respectively. It comes into pressure contact with the roof 3.

As described above, the windshield side molding portion 41A and the roof side molding portion 41B having different cross-sectional shapes are connected to each other via the corner molding portion 41C which is the cross-section changing shape portion 44.

The molding 41 including the windshield side molding 41A and the roof side molding 41B in addition to the corner molding 41C is formed by the variable cross-section extrusion method shown in FIG. )
As shown in the figure, although it is extruded as one continuous cord-shaped intermediate molded body W whose cross-sectional shape changes in the longitudinal direction, it is located between the windshield side molding part 41A and the roof side molding part 41B. A part of the corner molding portion (cross-sectional shape changing portion 44) 41C to be formed is locally cut out during extrusion molding to form a cutout portion 45, as shown in FIG. As shown in FIG.
Are integrally formed by secondary processing such as an injection molding method, and at the same time, a clip 57 as fixing means made of, for example, resin or metal is integrally fixed to the corner piece portion 56 by insert molding. Further, at the time of forming the corner piece portion 56, the groove portion 58 for receiving the terminal portion of the windshield upper molding 43 described above is simultaneously formed as shown in FIG.

The notch 45 can be easily processed by using the extrusion line shown in FIGS. 6 and 7 as in the first embodiment.

The reason why the corner piece 56 is separately formed is that the corner piece 56 is formed separately.
Is a corner molding portion (cross-section changing shape portion 44) which corresponds to a bent portion extending from the upper end portion of the front pillar 2 to the roof 3 as described above, but the cutout portion 45 is formed at the same time as the extrusion molding as described above. Since the 41C alone cannot completely follow the roof panel shape of the other party, it also serves to fix the clip 57 in order to add a shape that can completely follow the roof panel shape to the corner molding 41C. The corner piece 56 is formed separately.

The corner piece 56 is formed by setting the intermediate molded body W of the molding 1 in which the cutout 45 is formed together with the clip 57 in, for example, an injection molding die, and then forming the corner piece 56. Since the molding is performed by filling a predetermined resin material to be formed, as shown in FIG. 10B, the molding operation is performed in a state where the corner molding 41C is constrained to have a curved shape having a predetermined curvature. By doing so, the bending operation for giving the curl so that the entire molding 41 can be held in a substantially V-shape with an angle θ by itself is also performed at the same time. By doing so, the compatibility of the molding 41 after molding with the vehicle is further improved, and it is not necessary to actively bend the molding 41 when the molding 41 is attached, and the workability at the time of attaching the molding is also improved. It can be improved.
