It is formed to have. One of the inclined grooves 3a has an angle of a predetermined angle θ (for example, 45 degrees) to the right with respect to an axis n orthogonal to the guide ruler 2, and the other inclined groove 3b has a coaxial line n. Are formed to have the same angle to the left with respect to.

As shown in FIG. 4, below the table 1, there are provided cutters 5a and 5b for cutting the frame member W, and these cutters are provided with the inclined grooves 3a and 3b.
Are provided one by one. Each of the cutters 5a and 5b includes a disk-shaped blade 7 and a motor 8 for rotating the blade. The disk-shaped blade 7 is positioned so as to be orthogonal to the table 1 and substantially at the center of the inclined groove 3, and the upper end thereof is arranged so as to protrude upward from the upper surface of the table via the inclined groove 3. ing. A motor base 9 supporting a motor 8 to which a disk-shaped blade 7 is attached is guided along a guide rail 10, whereby the cutters 5 (5 a, 5 b) move with respect to the corresponding inclined grooves 3. It is free to move along its longitudinal direction. The cutter 5 is moved and adjusted along the longitudinal direction of the inclined groove as described above by moving the motor base 9 by a moving means (not shown) such as a cylinder.

FIG. 4 shows a state in which a part of the table 1 surrounded by the inclined grooves 3 (3a, 3b) is opened using a hinge portion.

Reference numeral 11 in FIGS. 3 and 4 denotes a cutter cover provided above the inclined groove 3 so as to cover the cutter 5.
Outside the cutter cover 11, an auxiliary cover 13 made of a transparent resin material such as acrylic is slidably provided so as to overlap the cutter cover 11 and to be coaxial with the cutter cover 11. The cover 13 is advanced and retracted by an air cylinder 15 provided on the side of the cutter cover 11 via a protrusion 13 a projecting laterally from the auxiliary cover 13.

In the case of this embodiment, a frame member W having a shape in which a flange W4 protrudes outward from a base W3 having a substantially triangular cross section is used as shown in FIG. ing. Accordingly, the guide ruler 2a also has a rectangular cross section in accordance with this, and the inner corner Wa of the frame component W is fitted to the corner 2aa of the guide ruler 2a for positioning. Further, as shown in FIG. 3, a portion corresponding to the inclined groove of the guide ruler 2a has been removed in advance, and is considered so as not to interfere with the moving cutter 5. Note that the front end of the auxiliary cover 13 is inclined in advance according to the inclination angle of the auxiliary cover, and when extended toward the guide ruler 2a, the front portion extends over the entire frame component W to be cut. Contact. Thus, the frame member W is guided by the guide ruler.
2a and the auxiliary cover 13 sandwich and cut
The part close to the position is in a pressed state.

On the guide ruler 2a, an end fixing member 17 for fixing an end of the frame member W and positioning the frame member W in the longitudinal direction is disposed in parallel with the guide ruler 2. Rail 1
8. Further, stoppers 20 and 20 are provided on the rail 18 so as to be slidable along the rail 18, and the end fixing member 17 is positioned by bringing an end of the stopper 20 into contact with the stopper 20 which is positioned in advance. It has become. Here, since there are two stoppers 20, two positions are determined with respect to the end fixing member 17.

Also, on the table 1, both inclined grooves 3
An air nozzle 21 is provided in the vicinity of the intersection of a and 3b so that the cut frame member W can be blown off and automatically removed from the table 1.

The cutting using the above-described apparatus is performed by cutting both cutters 5.
There are three methods, a method using (5a, 5b), a method using only one cutter 5a, and a method using only the other cutter 5b. These three methods are operated by a switch operation of an operation panel attached to the device. You can choose either.

Next, the operation of the end cutting device for the frame member W will be described. First, the frame component W to be cut is positioned at a predetermined position on the table 1 using the guide ruler 2a. In this case, as shown in FIG. 5, the inner corner Wa of the frame member W is fixed to the corner 2a of the guide ruler 2a.
In this state, the frame member W is pressed toward the user (X direction in FIG. 1) along the hand in this state.

Next, when a switch of a control panel (not shown) is turned on, the other motor 8 on the left side in FIG. 4 is driven to rotate the disk-shaped blade 7, and the other cutter 5b is rotated. It is moved along the inclined groove 3 by the moving means as it is. Thereby, the end of the frame component W positioned on the table 1 can be cut so as to have a 45 degree angle as shown in FIG. After the cutting, the other cutter 5b is returned to the original position again by the moving means, and the cut piece is compressed by the compressed air discharged from the air nozzle 21 provided near the apexes of the inclined grooves 3a and 3b. You are skipped forward.

When cutting by the other cutter 5b, the air cylinder 15 is driven in advance so that the auxiliary cover 13 extends along the cutter cover 11 to cover the upper part of the moving cutter 5 in advance. Therefore, even when the cutter 5 moves, the upper portion of the cutter 5 is not exposed, and high security is ensured.

Next, the cut frame member W is shifted to the right in FIG. 1, its end is fitted to the end fixing member 17, and is fixed again using the guide ruler 2a. At this stage, a switch (not shown) is turned on. Then, first, one cutter (the right cutter in the drawing) 5a moves to cut the frame component W (see FIG. 7). As a result, it is possible to obtain a frame member cut to a predetermined length.

Then, after one of the cutters 5a returns to its original position, the other cutter 5b moves and cuts off the end of the remaining frame member (see FIG. 7). As described above, in one process, the frame component W having a predetermined length can be obtained, and at the same time, the end of the frame component W to be cut next can be cut. I can do it.

Hereinafter, by sequentially repeating the above-mentioned operations, it is possible to efficiently cut the frame member W having a predetermined length and the end portion cut obliquely. In addition,
A plurality of frame components W can be obtained from the bar material having a fixed size. However, when the last frame component is obtained, one of the cutters 5 is used.
It suffices to move and cut only a, and then the end cutting using the other cutter 5b becomes unnecessary.

In the above embodiment, the inclined grooves 3 (3
a, 3b) and the cutter 5 (5
a, 5b) are arranged at an inclination angle of 45 degrees with respect to the guide ruler 2a, but the inclination angle can be variously changed according to the angle between the vertical member W1 and the horizontal member W2 on the frame to be manufactured. It is. For example, a combination of 30 degrees and 60 degrees may be used. In this case, the shapes of the vertical members and the horizontal members of the adjacent frame members may be different from each other.

[0025]

As described above, according to the present invention, the frame member is positioned at a predetermined position on the table using the guide ruler, and the cutter is moved by the moving means for cutting. Therefore, since the frame member is fixed during cutting, and the upper part of the cutter protruding above the table is partially covered with a slidable cover as appropriate, so that it is particularly safe. Excellent. The fixing of the frame structure material, be only pressed against the frame structure material guiding ruler, it is extremely easy since it is only necessary worker Ru pressed only by hand, excellent workability have. In addition, when a part of the cutter cover comes into contact with the frame material when the cutter cover advances, a frame is formed between the cutter cover and the guide ruler.
It is possible to sandwich the body constituent material and press the frame constituent material at the portion closest to the cut position, prevent the frame constituent material from being shaken, and stabilize the cut by the cutter. In addition, since the end fixing member is configured to be positioned at any one of two different positions along the length direction of the frame member, parts of the frame member having different lengths are replaced. Both can be cut at a predetermined angle without any need, and workability is also improved from this point. Further, if two inclined grooves and two cutters are provided, two end cutting processes can be performed in one step, so that excellent effects such as higher working efficiency can be achieved.
