2. Description of the Related Art Aluminum sash frames and the like have been conventionally often used for housing fittings, such as door frames and window frames. This type of sash frame uses a special shaped material made by extrusion molding etc. as a muntin, but usually the end faces of the shaped material are cut diagonally rather than simply butted and joined. It is assembled by sticking and joining the diagonally cut out parts.

By the way, diagonal cutting of such a shape material is
Conventionally, a worker would use a circular saw to set the material at the angle to be cut, then insert the circular saw into the material and perform the cutting process.

[Problems to be Solved by the Invention] However, in cutting a profile using such a conventional circular saw, the following problems remain to be solved.

First, the angle of the cutout groove at the end of the profile material varies depending on the sash frame to be assembled, and it takes a lot of time to set the profile material, resulting in poor work efficiency.

[0006] Secondly, depending on the material, the notch groove to be cut may have a very large inclination, and it is difficult to machine a notch groove with a large inclination with a circular saw machine whose rotation angle is fixed. It is.

The present invention has been proposed in view of the above circumstances, and its purpose is to be able to easily adapt to the cutting angle of the notch groove of the shape material that will become the workpiece, and to be able to easily adapt to the cutting angle of the notch groove of the shape material that becomes the workpiece. It is an object of the present invention to provide a cutting device that can easily cope with the processing of shapes and improve the work efficiency of cutting the shape material.

is formed.

The circular saw mechanism 11 includes a circular saw body 11 equipped with a disk-shaped circular saw that is rotated by the drive of a motor M.
A, and an arm 1 that supports the circular saw main body 11A in an upright state on the turntable 10b of the base 10 and supports the arm 1 at its upper end so as to be vertically rotatable via the rotation shaft 11a.
1B and the circular saw body 11A on the base 10 and the arm 11.
It is mainly composed of a turning lever 11C that turns the circular saw body 11A, and a cylinder device 11D that vertically turns the circular saw body 11A about a rotation shaft 11C.

The circular saw main body 11A is equipped with a disc-shaped circular saw (cutter) having teeth on its outer periphery, is attached with a cover 11b of the circular saw, and is connected to the arm 11B via a rotation shaft 11c. It is constituted by connected support members H, and has a basic structure in which the tip of the rod 11f of the cylinder device 11D is attached to the support member H.

Note that a resilient member for holding the support member H upward is interposed between the support member H and the arm 11B, and the circular saw is supported upward before the workpiece W is set. Of course, it will be done. Also, this circular saw body 11
A can also be tilted down by a handle portion 11g attached to the support member H, so that the cutting operation can be easily performed manually.

The arm 11B is integrally connected to the turntable 10b of the base 10, and also has a pivot lever 11C.
A positioning mechanism is provided for fixing the position of the turntable 10b. This positioning mechanism includes, for example, a structure in which the turntable 10b is fixed by tightening the turning lever 11C and pressing the support part 10c of the base 10 with the turning lever 11C, but it is possible to position the turntable 10b. Any structure may be used as long as it is a structure.

The cylinder device 11D has its base end pin-coupled to the support column 1g erected on the pedestal 1, and the rod 1
1f is attached to a support member 11d of the circular saw main body 11A, and the circular saw main body 11A is raised and lowered by expanding and contracting the rod 11f using air pressure, for example.

Finally, I would like to add a supplementary explanation to the clamping means 4 for fixing the workpiece W on the pedestal 1.
As shown in FIG. 1, a support member H is attached to the upper frame of the stand 1.
A cylinder device 4a supported through the cylinder device 4a and a presser member 4 attached to the rod tip of this cylinder device 4a
b, and the workpiece W is sandwiched between it and the angle member 1d of the frame 1 by moving the holding member 4b back and forth by the expansion and contraction of the rod 4c.

Next, in order to actually process a workpiece W such as an aluminum profile using the cutting apparatus configured as described above, first, the workpiece (for example, an aluminum profile) W is placed on the pedestal 1, and the clamping means After the workpiece W is clamped and fixed between the angle material 1d by the cylinder device 4a constituting the part 4, the circular saw mechanism 3 is rotated using the rotation lever 11C to determine the position of the circular saw, and the position of the circular saw for raising and lowering is determined. When the circular saw body is tilted around the rotation shaft 11c by the cylinder device 11D, the end face of the workpiece W on the mount is notched.

[0023] When cutting the workpiece W at a large angle, the reference line 10a of the base 10 is inclined and the second cutter means 3 attached to the pedestal 1 is used to cut the circular saw body. The angle of the notch can be increased.

In this embodiment, two circular saw mechanisms are used to separately cut out the workpieces W on the left and right sides of the pedestal 1, so it is possible to easily change the workpieces, and the work can be done easily. Efficiency can be improved.

Furthermore, in the embodiment, the second cutter means 3
Since the base 10 is installed with the reference line 10a of the base 10 inclined with respect to the length direction of the pedestal 1, the notch angle of the circular saw to the workpiece W can be made large,
This has the advantage of being able to easily accommodate the formation of notch grooves at various angles.
