The workpiece is cut in a state where the main body vice device clamps and fixes the workpiece fed by the material feeding action of the material feeding vise device. There is a type of cutting machine in which a front vise device is provided in front of the cutting position so as to be movable back and forth in order to move the cut pieces separated from the workpiece forward by cutting the workpiece as described above.

As mentioned above, in a cutting machine equipped with a front vise device, if the cutting head supporting the cutting tool for cutting the workpiece is simply provided with a vertically movable cutting head, the front vise device must be placed close to the cutting position. It is also possible to hold short cut pieces.

However, in order to cut a long workpiece diagonally, the cutting head is mounted vertically on a rotating base that can freely rotate in the front and back directions, and both the front vise device and the rotating base are common. Avoid interference between the front vise device and the forward protruding parts, such as chip receivers, which are mounted on the base and are provided on the base and protrude forward when the pivot base rotates forward. In order to
There is also a limit to how close the front vise device can be to the cutting position.

(Problems to be solved by the invention) As mentioned above, in a type of cutting machine in which the swing base swings back and forth, a space is required to avoid interference between the swing base and the front vise device.
If the cut piece is short, it may be difficult to hold it in the front vise. Furthermore, it is difficult to provide a support table or the like for supporting the cut pieces in the area where the front vise device moves back and forth, and the cut pieces may fall accidentally.

[Structure of the invention] (Means for solving the problems) In order to solve the conventional problems as mentioned above,
In the present invention, a guide bar whose rear free end extends to the vicinity of the cutting position is supported on a support stand placed in front of the cutting position where a long workpiece is cut, and the guide bar is placed at a position above the guide bar. The rear end of the support table, the front end of which is supported by the support base, is extended to the vicinity of the cutting position, and the fixed vise jaw is provided at one end of the vice frame, which is supported by the guide bar so as to be movable back and forth. is provided so as to protrude upward from the support table, and a movable vise jaw is movably provided on the other end side of the vice frame, facing the fixed vise jaw.

(Function) In the above configuration, since the rear end of the guide bar is a free end, the guide bar can be extended to the vicinity of the cutting position without interfering with the front protrusion of the swing base that is freely rotatable in the front-rear direction. This means that the rear end side of the support table can be brought close to the cutting position.
Furthermore, the vise frame supported by the guide bar so as to be movable back and forth can be brought close to the cutting position, and the cut piece can be held by the vise jaw provided on the vise frame.

(Example) In order to understand the overall configuration of a cutting machine embodying the present invention, reference is made to FIG. 4. In FIG. 4, a horizontal band saw machine 1 is illustrated as an example of a cutting machine. However, the present invention is not limited to horizontal band saws, but can also be applied to various cutting machines such as circular saws and disc cutters equipped with disc-shaped cutting tools.

In FIG. 4, the horizontal bandsaw machine 1 illustrated as an example of a cutting machine has a swing base 7 that is mounted on a fixed base 3 via a pin 5 and can freely swing in the front and rear directions (front and back directions in the drawing). A cutting head 11 equipped with a band saw blade as a cutting tool 9 is mounted on the swing base 7 so as to be movable up and down. A main body vice device (not shown) for clamping and fixing the workpiece W is provided.

In the horizontal bandsaw machine 1 having the above configuration, after the swing base 7 is appropriately turned in the front and back direction with respect to the fixed base 3, the workpiece W is
is clamped and fixed, and then the cutting head 11
is lowered to cut the work W. Note that since the cutting machine having the above configuration is well known, a more detailed explanation will be omitted.

When cutting the workpiece W as described above, in order to support the cut piece separated from the workpiece W,
A cut piece support device 13 is arranged in front of the cutting position. This cut piece support device 13 is mounted on the fixed base 3 in front of the rotating base 7.

More specifically, as shown in FIG. 1, the cut piece supporting device 13 includes a support table 15 that supports the cut piece (not shown), and also supports the cut piece in the forward direction (leftward in FIG. 1). It is equipped with a front vise device 17 that can be freely moved in the direction (direction).

To explain in more detail, as is clear from FIG. A guide bar 21 (the right end in FIG. 1) extends beyond the front projection 7P provided on the swing base 7 to near the cutting position and is integrally supported by bolts or the like. . Furthermore, the front end portion of the support table 15 is integrally attached to the support table 19 at a position above the guide bar 21, with the rear end portion extending to the vicinity of the cutting position.

The support table 15 includes a pair of frames 23 whose front ends are fixed to the support stand 19, and a large number of support rollers 25 rotatably provided.
A notch is appropriately formed at the rear end of the frame 23 to avoid interference with the cutting tool 9 when the swing base 7 swings forward.

A box-shaped vice frame 27 constituting the front vice device 17 is supported on the guide bar 21 so as to be movable back and forth. This vice frame 27 is
It is located above the front protrusion 7P of the swing base 7, and a fluid pressure cylinder 29 is attached to the vice frame 27, with the tip of a piston rod 29P (see FIG. 2) fixed to the support base 19. be. Further, the vice frame 27 is provided with a frame support portion 31 that supports the lower surface of the frame 23 on the support table 15 in a freely movable manner. Therefore, by the operation of the fluid pressure cylinder 29, the vice frame 27 supports the support table 15 and is moved back and forth.

A fixed vice jaw 33 (see FIG. 3) that protrudes upward from the support table 15 is attached to one end of the vice frame 27, and the support table 1 is attached to the other end of the vice frame 27.
A bracket portion 35 is formed that protrudes upward from the bracket portion 5. A vice cylinder 37 is attached to this bracket portion 35, and a piston rod 3 that can freely reciprocate in this vice cylinder 37 is attached to the bracket portion 35.
A movable vice jaw 39 facing the fixed vice jaw 33 is attached to 7P. As shown in FIG. 1, the rear sides of the fixed vise jaw 33 and the movable vise jaw 39 are as shown in FIG.
