As shown in FIG. 9, a fixed blade 12 and a movable blade 13 are provided, and the reinforcing bar 1 is disposed closer to the fixed blade 12 than the movable blade 13 in the longitudinal direction of the reinforcing bar 1 disposed between the two blades 12, 13. The first support portion 14 for supporting is provided in a fixed state,
A second support portion 25 (conveyor) for supporting the rebar 1 is provided on the movable blade 13 side from the fixed blade 12 in the longitudinal direction of the rebar 1 and on a side opposite to the movable blade 13 in the rebar radial direction. Some were provided so as not to move vertically.

問題点がある。According to the above-described conventional rebar cutting apparatus, the movable blade 13 is lowered in the direction approaching the fixed blade 12 to cut the rebar 1 disposed between the two blades 12, 13. In doing so, the cut-off rebar (cut-off rebar) 1b located on the side of the movable blade 13 from the cutting position rotates clockwise about the second support portion 25 as shown in FIG. There is a danger that there is a problem that noise, vibration, and recovery of the cut-off reinforcing bar 1b become complicated.

の前工程として、わざわざ端面加工が必要となる。Therefore, as shown in FIG. 10, the position of the second supporting portion 25 is set lower than that of a conventional rebar cutting device, as shown in FIG. It is conceivable that the two support portions 25 are unlikely to become fulcrums of rotation. However, in this case, with the lowering of the movable blade 13 at the time of cutting the reinforcing bar, the cut-off reinforcing bar 1b is cut with the fixed blade 12 as a fulcrum while turning in the opposite direction to the clock, and the cut-down reinforcing bar 1b is cut. Has a new problem that the cut surface G tends to be greatly inclined (not a perfect circle) with respect to the axis. However, if the cut surface of the reinforcing bar is greatly inclined with respect to the axis, for example, it is likely to cause trouble during pressure welding work with another reinforcing bar, and it is necessary to perform end face processing as a pre-process of the pressure welding operation. .

And the first support from the movable blade in the longitudinal direction of the rebar.
On the outer side in the opposite direction to the holding portion, a second support portion that supports the rebar movably along the movable direction of the movable blade is provided, and the second support portion is moved with the movable blade being cut with respect to the rebar. Is provided with an evacuation mechanism that allows the movement of the object.

たことが解消される。According to the characteristic structure of the rebar cutting device of the present invention, the reinforcing bar is supported on the fixed blade side of the movable blade in the longitudinal direction of the reinforcing bar disposed between the fixed blade and the movable blade. A supporting portion, the movable blade being on the movable blade side in the longitudinal direction of the rebar and on the side opposite to the movable blade in the rebar radial direction, movably along the movable direction of the movable blade. A second support portion for supporting the reinforcing bar is provided, and a retreat mechanism is provided to allow movement of the second support portion along with the movable cutting of the movable blade with respect to the reinforcing bar. It is possible to allow the movement of the second support portion along the direction. That is, since the second support portion can move together with the movable blade while supporting the cut-off rebar (cut-off rebar), the second rebar is supported so that the rebar is not largely inclined with respect to the axis thereof. Parallel movement in the radial direction (or movement in a state close to parallel)
As a result, it becomes difficult for the rotational force around the second support portion to act on the cut-off rebar, and it is possible to prevent flip-up caused by the rebar cutting. Then, the rebar is parallel to (or nearly parallel to) the radial direction so as not to be greatly inclined with respect to its axis.
It can be cut while supporting it in a state where it can be moved, so that it is possible to make a cut surface along the radial direction of the cut-off rebar, and by cutting while bending with the fixed blade as a fulcrum as in the past, The inclination of the cut surface is eliminated.

The above-described operation can be achieved, and only a small amount of modification is required to the conventional device.

State), the second support portion can function as a support portion that performs the above-described action, and the set value of the reinforcing bar support force is particularly set within a range that does not cause jumping up. By setting to the maximum value at the beginning of the cutting operation,
It is possible to support the cut-off rebar in a state where there is no bending, and it is possible to achieve more accurate cutting with less inclination of the cut surface.

It is possible to perform rebar cutting with high cutting accuracy without generating vibration, and furthermore, it is possible to realize efficient rebar processing work by omitting end face processing of rebar in a later process.

う。<2> The retracting mechanism E is not limited to the spring 16 described in the previous embodiment.
When the reinforcing-bar supporting force of the second supporting portion 15 exceeds a predetermined value, a fluid pressure supporting device 17 that receives the second supporting portion 15 so as to be movable along the contact direction of the reinforcing bar 1 may be used. . The fluid used for the fluid pressure support device 17 is as follows:
For example, oil, water, air and the like are mentioned as examples.
The configuration of the fluid pressure support device 17 is, for example, as shown in FIG.
As shown in the figure, the cylinder 1 communicated with the fluid flow path
9 to receive the reinforcing bar supporting force acting on the second supporting portion 15, and the relief valve 20 provided in the fluid flow path, the second supporting portion when the reinforcing bar supporting force exceeds a predetermined value. It may be configured to allow 15 movements. These are collectively called an evacuation mechanism.
