Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jig used for cutting and molding a reinforcing fiber mat used for molding a fiber-reinforced resin.

[0002]

[Prior Art]

 Recently, fiber reinforced resin (FRP) has come to be used for outer panels of automobiles. At the time of molding the FRP, a preform mat in which reinforcing fibers such as glass fibers are previously formed into a predetermined shape is used. Conventionally, in forming this preform mat, a long glass fiber material is manually cut using a cutting device such as an electric scissors. In Japanese Utility Model Laid-Open No. 61-205789, a slide cutter provided with a spring is provided with a holding piece having a scale provided on a holding plate and a slide rail and a groove hole for mounting a blade provided on a guide plate. A cutting tool that combines a cutter and slide rails is described.

[0003]

[Problems to be solved by the device]

 In the above conventional cutting method, it is difficult to maintain the straightness of the cutting tool, and it is also difficult to cut a long straight portion. Further, since the cutting device such as the electric scissors is heavy, workability is poor. In the cutting tool described in the above-mentioned publication, the straightness of the cutter is maintained by the slide rails, but the glass fiber mat is an unstable material to maintain its shape, and therefore, it cannot be pressed from both sides. If you do not cut it, there will be leftovers. In addition, the cutting powder of glass fibers scatters around when cutting, which deteriorates the working environment.

The present invention solves the above problems, suppresses the bulging of the work such as glass fiber having an unstable shape, prevents the uncut portion of the work, and maintains a good working environment to efficiently and accurately perform the work. The object is to provide a jig that can be cut into pieces.

[0005]

[Means for Solving the Problems]

 According to the present invention, a rail is provided in a gutter-shaped jig body having a fixture to be attached to a workbench, and a gutter-shaped cover having both side edges facing the both side edges of the jig body can be attached to and detached from the jig body. It is a jig for cutting such as a fiber mat in which a cutter installed and holding a holder is moved on the rail of the jig body.

[0006]

[Action]

 When the cutting part of the work is set on the jig body attached to the side of the work table and the cover is placed over the work and fixed, the work is pinched from both sides by the jig body and both sides of the cover. When the holder of the cutter is placed on the rail of the jig body and the cutter is operated to move forward, the cutter is guided by the rail and advances in the jig while cutting the work along a predetermined trajectory. .. In this case, since the work is sandwiched from both sides of the cutting part from above and below respectively, even a work with unstable shape such as glass fiber can be cut accurately without leaving uncut residue, and the cutting chips produced during cutting are Since the periphery of the cutting part is covered by the jig body and the cover, it does not scatter around.

[0007]

【Example】

 1 shows an embodiment of the present invention, and FIG. 2 is a sectional view taken along line XX of FIG. The jig of the present invention is to fix the work W made of glass fiber or the like from both sides by fixing the work W such as glass fiber at both edges of the gutter-shaped hollow body which is divided into two parts, and move the cutter on the rail inside the hollow body. With a basic configuration, a rail 2 for guiding a holder 5 attached to a rotary cutter 4 is provided inside a hollow semi-cylindrical jig body 1. This jig body 1 is operated by a fixture 3. It is attached to the table 10. The cover 6 is formed in the shape of a hollow semi-cylindrical gutter similar to the jig body 1, and is placed over the work W set on the jig body 1 as shown in FIG. It is configured to be fixed to 1.

Next, the work of cutting a work such as glass fiber using the jig of the present invention will be described. As shown in FIG. 4, the work W is pulled out from the material roll and placed on the workbench 10, and the cutting portion of the work W is set on the jig body 1 attached to the side of the workbench 10. In this case, since the cover 6 is pivotally supported 8 on the jig body 1 at the rear end thereof, work is performed with the front side of the cover 6 lifted. Although not shown, if a spring is provided between the jig body 1 and the cover 6 at the rear end to keep the cover 6 open as shown, the work W Can be easily set. When the cover 6 is put on the work W and fixed to the jig body 1 with the clamp 7, the work W is sandwiched by the jig body 1 and the both sides of the cover 6 from both sides as shown in FIG. A handle 9 with a handle is attached to the cutter 4, so that the holder 5 of the cutter 4 is placed on the rail 2 of the jig body 1, the switch installed in the handle 9 is turned on, and the blade of the cutter 4 is rotated. Then, when the grip 9 is pushed forward, the cutter 4 is guided by the rail 2 and advances in the jig while cutting the work W along a predetermined locus. In this case, the operator only has to push the grip 9 forward, which facilitates the work, and since the work W is sandwiched from both sides of the cut portion from above and below, it does not have the shape like glass fiber. Even a stable work can be cut accurately without leaving uncut residue. Further, the cutting powder generated during cutting does not scatter around because the periphery of the cutting portion is covered with the jig body 1 and the cover 6.

Next, another embodiment of the present invention will be described with reference to FIG. The jig body 11 and the cover 16 are each formed in a rectangular gutter shape, and the rail 12 is provided on the jig body 11. A plurality of pairs of wheels 15 are attached to both sides of the cutter 4, and the wheels 13 are rotated by the motor 13 installed in the cutter 4 via the reduction gear 14 so that the wheels 15 travel on the rails 12. .. Further, the cover 16 is provided with a suction port 19 for attaching a hose 18 connected to the dust collector 17. The mounting on the workbench and the setting of the work W in this embodiment are the same as those in the embodiment of FIG. In this embodiment, the cutting device 4 self-propels on the rail 2 of the jig body 1 by controlling the motor 13 of the cutting device 4 remotely, so that a long part can be cut and the cutting part is straight. Not limited to this, by forming the jig body 1 and the cover 6 in a curved shape, it is possible to cut the work W including the curved line portion. Furthermore, the cutting dust generated during cutting is collected from the cover 16 to the dust collector 17, does not scatter in the surroundings, and prevents dust from entering the equipment moving in the jig to minimize damage to the equipment. Can be prevented.

The cutting device 4 used in the present invention is not limited to the rotary cutter shown in FIG. 4, but may be air scissors or electric scissors as shown in FIG. The cross-sectional shape of the cover 6 is not limited to a circular shape or a rectangular shape, but may be a hexagonal shape or any other shape.

[0011]

[Effect of the device]

 According to the present invention, a work having an unstable shape such as a glass fiber mat can be fixed from both sides while suppressing its bulge, and no uncut residue is generated when the work is cut by a cutting device. Further, since the cutter is guided by the jig rail, the cutting work can be performed accurately and easily, and the dimensional accuracy of the product can be secured. Furthermore, since the scattering of cutting chips at the time of cutting can be prevented, a good working environment can be maintained and damage to the equipment used can be prevented to a minimum.
