And move along the vertical table 4. Thereby, a to-be-cut object can be cut | disconnected horizontally in a predetermined height position.

  Further, even when the workpiece is cut horizontally, the angle position of the movable arm 51 is adjusted, and even when the horizontal heat ray 8 is in the lowest state, it may be desired to cut at a lower height position. In this case, the object to be cut can be cut even at a lower height position by adjusting the height position of the horizontal table 3.

  On the other hand, when the object to be cut is cut vertically at a predetermined lateral width position, the movable arm 51 is removed from the support shaft portion 16 of the gantry 2 as shown in FIGS. The vertical hot wire 7 is stretched between the upper end support means 43 and the lower end support means (not shown) located below the horizontal table 3.

  Then, the angular position of the vertical table 4 is adjusted and fixed by the fixing means 34 so that the separation distance between the vertical heat ray 7 and the vertical table 4 becomes a desired distance. Then, the current adjusting device 61 is adjusted so that a current having a current value appropriate for cutting the object to be cut is supplied to the vertical heating wire 7 and energized to cause the vertical heating wire 7 to generate heat. Is moved along the vertical table 4. Thereby, a to-be-cut object can be cut | disconnected perpendicularly | vertically in the position of a predetermined width direction.

  According to the above-described hot-wire cutting device 1, the support direction of the hot wire can be appropriately selected from vertical or horizontal according to the shape of the object to be cut. Therefore, when the object to be cut is placed on the horizontal table 3 and moved along the vertical table 4 for cutting, the object to be cut can be cut in the most stable posture state.

  For example, the state of the posture in which the workpiece having a block shape extending in the axial direction and having a substantially rectangular cross section is most stable on the horizontal table 3 is that the surface which is the longitudinal direction in the cross section is in contact with the horizontal table 3. The posture state. Therefore, the horizontal hot wire 8 is selected when the workpiece is cut so as to be divided in the short section direction, and the vertical hot wire 7 is selected when the cut object is cut so as to be divided in the cross section longitudinal direction. Can be cut in the most stable posture. Accordingly, the posture stability of the object to be cut can be increased, workability can be improved, and high cutting accuracy can be obtained.

  Further, by changing the angular position of the movable arm 51, the position in the height direction for cutting the workpiece can be easily adjusted to an arbitrary position, and the angular position of the vertical table 4 can be changed. Thus, the position in the lateral width direction for cutting the workpiece can be easily adjusted to an arbitrary position.

  Therefore, there is no need to provide a complicated moving mechanism as in the prior art, the structure of the device 1 can be simplified, and the weight and size can be reduced. In particular, in the present embodiment, since the movable arm 51 can be accommodated in the accommodation position, it is possible to further reduce the size and to carry it easily.

  Therefore, for example, the apparatus 1 can be carried to a place where construction is actually performed at a construction site, and a workpiece can be cut according to the situation on the site, so that the construction period at the construction site can be shortened and construction costs can be reduced. . In addition, since the structure is simple, the apparatus can be provided at a low cost, and there are few failures, it is robust and maintenance-free, and the running cost can be reduced.

  In addition, this invention is not limited to the above-mentioned embodiment, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in the above-described embodiment, the case where the gantry 2 is made of an aluminum alloy and the horizontal table 3 and the vertical table 4 are made of veneer plywood has been described as an example. However, it is lightweight and highly rigid and has heat resistance. Anything is acceptable.

  In the horizontal table 3 and the vertical table 4, the through holes 23 and 33 through which the heat wires 7 or 8 are inserted have been described. However, instead of the vertical holes, grooves cut out from one side of the table may be used. Of course, it is sufficient if the extending position of the heat ray can be changed (left side direction for the horizontal table 3 and vertical direction for the vertical table 4).
