Description

[Detailed description of the invention] The present invention relates to a cutting device, and in particular, cuts a so-called panel member, etc., in which a core material is provided on one side of a plate-shaped face material into a predetermined shape at the same time. This invention relates to a cutting device that performs cutting and machining.

Conventionally, when manufacturing various panels such as wall panels and formwork panels, it is necessary to attach a core material with a tenon (handle) formed at the end to one side of the panel that has been cut into a predetermined shape. Alternatively, after attaching the core material, a tenon was formed, and then a core material for the wood end having a notch to be joined to the tenon was attached. Therefore, when manufacturing a panel with a predetermined shape, cutting the face material and forming tenons on the core material must be performed in separate processes, and depending on the shape of the panel to be manufactured, The processing in each of the above steps is also complicated and requires various changes.

An object of the present invention is to provide a cutting device that can easily and accurately manufacture panels of a predetermined shape from a so-called panel member in which a core material is provided on one side of a plate-shaped face material. .

In this invention, a rotary cutting blade that can move linearly with respect to a surface plate on which a panel member, which is a workpiece, is placed, and a rotary cutting blade that has a smaller diameter than this rotary cutting blade, rotate at the same time. are provided adjacent to each other on the shafts, so that when the face material of the panel member is cut by the cutting rotary blade, a tenon is formed by the cutting rotary blade at a position where the end of the core material is to be formed. At the same time, the cutting line guide section, which moves in accordance with the movement of the cutting rotary blade and the cutting rotary blade, is inserted into the cutting part of the workpiece to maintain the cutting rotary blade in a predetermined direction. Let's achieve the above objective by optimizing the direction and pressing the workpiece against the surface plate side using the holding tool on the upper end of the cutting line guide to eliminate panel members from springing up and optimizing cutting and machining. That is.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

As shown in FIG. 2, the cutting rotary blade 9 is
It is said to have the shape of a so-called running saw with a special blade attached. That is, this cutting rotary blade 9
has a plurality of flat blade pieces 13 having a predetermined width,
These flat blade pieces 13 are arranged along an imaginary circumference centered on the rotating shaft 7 so as to face in the connecting direction of the imaginary circles. Further, the cutting rotary blade 9 and the cutting rotary blade 8 are configured to protrude from the machining groove 14 provided in the surface plate 1 by a predetermined height.

As shown in FIG. 3, both ends of the rotating shaft 7 are supported at predetermined positions on a support plate 21 that is perpendicular to the surface plate 1 and parallel to each other, and is supported by a pulley 5. The other end of the drive belt 6 is looped around a drive pulley 24 of a drive motor 23 mounted on a bottom plate 22 whose both ends are fixed to a support plate 21.

A long oval hole 25 extending vertically in the vertical direction is bored at a predetermined position of the support plate 21.
Both ends of the guide rod 26 are respectively inserted into the holes 25, and the guide rod 26 is configured to be able to vertically move up and down along the elongated hole 25.

The guide rod 26 is fitted into the cut portion of the panel member 4 as a workpiece to be cut by the cutting rotary blade 8 at a position corresponding to the cutting rotary blade 8 of the rotating shaft 7 (see FIG. 1). A lower end portion of a plate-shaped guide piece 27 serving as a cutting line guide portion is fixed.

A roller body 28 serving as a presser is rotatably supported on both sides of the upper end of the guide piece 27 . One end of this roller body 28 is attached near both ends of the guide rod 26, and the other end is attached to the fixed rod 29.
The surface plate 1 is biased vertically downward by a pair of compression springs 31 as biasing means attached to the surface plate 1.
It is configured to roll on the upper end surface of the panel member 4 placed thereon along the direction of the cutting line and to press the panel member 4 against the surface plate 1 side.
Note that the fixed rod 29 is positioned vertically below the guide rod 26 at a predetermined distance from the support plate 21.
is fixed on both sides. Further, the guide piece 27 and the roller body 28 constitute a guide mechanism 30.

A plurality of small wheels 32 are rotatably supported on the support plate 21 so as to project horizontally at predetermined intervals, and these small wheels 32 are mounted on a rail member 33 having a substantially C-shaped cross section. It is slidably inserted. This rail member 33 is installed below the surface plate 1 along the longitudinal direction of the machined groove 14 on both sides of the machined groove 14 via fixtures (not shown), and is installed on both sides of the machined groove 14 . , the rotary cutting blade 9, and the guide mechanism 30 are each configured to be able to move along the machining groove 14 while maintaining a state in which they protrude from the machining groove 14 by a predetermined height.

Next, the operation of this embodiment will be explained with reference to FIGS. 4 and 5.

The panel member 4 as a workpiece placed on the surface plate 1 in a predetermined direction is cut by a cutting rotary blade 8 along the processing groove 14 as shown by the inclined two-dot chain line A in FIG. Cutting rotary blade 9 and guide mechanism 30
When the core material 3 is moved integrally, the core material 3 is sequentially cut with a predetermined width by the rotary cutting blade 9 up to a predetermined height from the surface plate 1, and a tenon 41 (see FIG. 5) is formed. At the same time, the core material 3 and the face material 2 at locations above the predetermined height are sequentially cut by the cutting rotary blade 8.

At this time, a guide piece 27 that moves together with the cutting blade 8 along this cutting part is fitted into the cut part of the panel member 4 cut by the cutting rotary blade 8. Since the orientation of is maintained in a predetermined direction, the cutting line is formed more linearly. Moreover, since the panel member 4 is pressed against the surface plate 1 side by the roller body 28, the panel member 4 does not spring up or flap during cutting or machining, and the cutting or machining can be performed properly. That will happen.

In this way, after the cutting of the face material 2, the cutting of the core material 3, and the formation of the tenon 41 in the portion that will become the end after cutting are performed at the same time, as shown in FIG. A panel having a predetermined shape is manufactured by attaching a core material 43 for the butt end, in which a notch 42 is formed to connect to the tenon 41, along the cut edge of the face material 2.

According to this embodiment, the following effects can be obtained.

That is, the cutting of the face material 2, the cutting of the core material 3, and the formation of the tenon 41 in the portion that will become the end after cutting are all performed in one work process, so that work efficiency is dramatically improved.

Furthermore, the panel member 4 may be cut from any direction of inclination, and tenons 41 are formed along the inclination direction at the end of the core material 3 at the cutting edge, so that tenons 41 are formed at predetermined intervals. A panel member 4 of a predetermined size consisting of a face material 2 provided with a core material 3 in a lattice pattern is prepared, and panels of various shapes can be easily produced by cutting this panel member 4 into appropriate predetermined shapes. can be manufactured.

Moreover, since the guide mechanism 30 consisting of the guide piece 27 and the roller body 28 is provided, the cutting and cutting of the panel member 4 is always performed properly and linearly, and the cut surface and cut surface are finished neatly and the final This has the effect that the panels manufactured in this way can also be finished neatly. This is particularly effective when cutting and cutting are performed in a direction oblique to the core material 3.

Further, the cutting rotary blade 8, the cutting rotary blade 9, and the guide mechanism 30 are integrally connected to the rail member 33.
Since the panel member 4 is configured to be moved along the surface plate 1, it is not necessary to send the panel member 4 and it is possible to process a large area. It is extremely easy to operate as it can be machined in any direction by aligning the positions, and it is also easy to use an automatic feed mechanism.

Further, a cutting rotary blade 8 and a cutting rotary blade 9
are removably attached by fasteners 11, so if the rotary blades 8 and 9 become worn or damaged, or if the shape of the tenon needs to be changed, they can be replaced separately. can.

In the above embodiment, the rotary cutting blades 9 are attached to both sides of the rotary cutting blade 8, but when the panel member 4 is cut, a tenon is formed only on one of the cutting blades. In cases such as when
may be attached.

Furthermore, although the cutting rotary blade 9 has been described as having a single thick blade shape with a blade surface parallel to the rotation axis 7,
In cases where the tenon is to be formed at the same time as the place to attach the built-in ridge beam, or depending on the shape of the tenon, the tenon is not limited to a single thick blade shape, but may have multiple thick blade shapes with different diameters. You can. Furthermore, the blade surface of the rotary cutting blade 9 may be inclined with respect to the rotation axis 7, and in such a case, a roof panel or the like that does not require a sloped purlin or the like is manufactured from the panel member 4. can do.

Further, the cutting rotary blade 8 and the cutting rotary blade 9 may be integrally fixed to the rotary shaft 7 and cannot be replaced separately.

Further, although the cutting rotary blade 9 has a plurality of flat blade pieces 13, the present invention is not limited to this, and for example, a substantially file-like cutting surface or a wave-like cutting surface may be formed on the circumferential surface of a short cylindrical body. It may be something that you have. However, according to the flat blade piece 13 described above, there is an effect that the tenon 41 is formed neatly.

In addition, although the cutting line guide section is described as a plate-shaped guide piece 27, it is not limited to a plate-shaped one, and may be, for example, a plurality of rod-shaped members or a frame-shaped one made of bent rod-shaped members. You can. The presser is not limited to the roller body 28, but may have a shape in which the tip of the presser in the direction of movement is bent upward, for example, a plate-like object shaped like a ski or a rod-like object. Alternatively, another presser may be provided on the front side of the rotary cutting blade 8 separately from the roller body 28.
