切断機および切断方法

Japanese Patent JP7040948

B2

To realize easy and accurate cutting at an interest site.SOLUTION: A structure has a configuration that a front surface along vertical direction as a main surface of a first plate is attached to an end surface along vertical direction of a second plate, and an upper end surface of the first plate and an upper end surface of the second plate are attached to a lower surface of a cover part. A cutting machine 1 is used for cutting from front side of the first plate along the lower surface of the cover part at an interest site on a first plate which opposes to the end surface of the second plate and arranged at a position near the lower surface of the cover part. The cutting machine 1 comprises a cutting blade 2 and a cutting machine body 3. The cutting blade 2 is arranged substantially parallel to the lower surface of the cover part, has a long thin plate shape, and is provided with a tooth part on an edge extending in longitudinal direction. The cutting machine body 3 is arranged on the opposite side of the lower surface of the cover part relative to the cutting blade 2, and moves the cutting blade 2 in a reciprocation manner in movement direction along longitudinal direction while holding an end of the cutting blade 2 in longitudinal direction. Thereby, the interest site of the first plate may be easily and accurately cut.SELECTED DRAWING: Figure 3
