DESCRIPTION OF THE PREFERRED EMBODIMENTS According to the present invention, a side end of a long member on a cutting table is clamped by a side stopper, and the long member is pressed onto the cutting table by a clamp means from above, and a slit of the cutting table is formed. Is a device for cutting a long member at right angles to the longitudinal direction by a circular saw as a cutting means by a cutting means provided below.

The cutting table is provided with a slit in its width direction so that the rotating circular saw blade protrudes above the slit. Furthermore, the clamping means is provided on each of the front and rear sides of the slit, and is a pressing member which is moved up and down by a pressing cylinder.
Preferably, a plurality of long members are collectively pressed and fixed, and the cutting means is located below the slit of the cutting table. In particular, the cutting means attaches a cutting blade of a circular saw to the upper end of a turning arm having a lower end pivotally attached thereto, and presses a top-side portion of the turning arm with a turning cylinder, thereby turning the turning table along with the turning of the turning arm. The cutting blade portion projecting upward from the slit reciprocates in a direction crossing the long member while drawing an arc, and the cut surface of the long member after cutting is perpendicular to the longitudinal direction.

When the long member is cut, the distal end stopper of the long member is stopped at the desired position set and input, and the distal end of the long member placed on the cutting table is brought into contact with the distal end stopper. Along the side stopper of the long member provided at the edge of the cutting table so as to contact the longitudinal end of the long member on both front and rear sides of the slit so as to straddle the slit. After being brought into contact with each other and positioned, clamped by the clamp means, and cut by the circular saw.

[0010] With such a structure of the cutting device, even if the cross section is a hollow long member having a square-shaped portion, deformation of the vicinity of the cut is not caused by the pressing of the cutting blade at the time of cutting. Since the long members placed in parallel can be cut at once by clamping the upper and lower surfaces and the side surfaces, workability is good.
