Description of the Related Art An extruded shape formed by hot extrusion by an extruder is cooled and then stretched by a tension straightening machine to straighten distortion such as bending. For example, as shown in Japanese Utility Model Laid-Open No. 61-42645, a traveling table is provided on the extrusion side of an extruder to push an extruded profile onto the traveling table, and the extruded profile is conveyed to a cooling table and cooled. After that, it is conveyed to a tension straightening machine to correct distortion such as bending.

ックをシリンダによって移動するものである。Since the extruded profile contracts when it is cooled on the cooling table, the positions of both ends of the extruded profile after cooling deviate in the short direction substantially symmetrically with respect to the longitudinal direction. Come on. Further, the amount of shrinkage differs depending on the cross-sectional shape of the extruded shape member, and the amount of positional displacement of the end portion is not constant. Further, when contracting, warpage occurs in the longitudinal direction of the extruded profile. On the other hand, the tension straightening machine is disclosed in, for example, JP-A-2-290.
As disclosed in Japanese Patent No. 616, the head stock and the tail stock hold both ends in the longitudinal direction of the extruded profile, and the head stock is moved by a cylinder.

持部に正しく合致せずに人手を介してセットしていた。As described above, since the end position of the extruded profile after cooling varies and parallel feed is difficult due to the influence of warpage or the like, the longitudinal direction of the extruded profile when conveyed to the tension straightening machine is difficult. The ends were not set correctly on the grips of the headstock and tailstock and were set manually.

It is supported so as to be vertically rotatable over the stop position in the transport direction, and is vertically rotated by the cylinder 19.
The operation of the stopper 17 may be oscillated perpendicularly to the carrying direction or moved in parallel. The stopper 17 is provided near the center position of the tension straightening machine 7 as shown in FIG. It may be straightened and then conveyed to the next step as a non-stop position.

The upper movable gripping piece 15 and the lower movable gripping piece 14 of the shape material holding machine 12 hold one longitudinal end of the extruded shape material 10 and cool it in that state, or the next extruded shape material is extruded from the extruder 3. Hold until molded. As a result, the extruded profile 1
0 is cooled, and the cooled extruded profile 10a contracts while being bent as shown by the solid line in FIG. 3, but the position of one end 10b in the longitudinal direction of the cooled profile 10a is at the profile grip 1
Since it is gripped by 2, the positioning is always constant.

に順次当たることによってほぼ真直ぐに矯正される。The section extruded by the section grasper 12 is released, and the cooled extruded section 10a is conveyed by the conveying section 11. At this time, the stopper 17 is at the stop position, and the cooled extruded profile 10a that has been conveyed comes into contact with the stopper 17 and is straightened in a direction orthogonal to the conveying direction. That is, when the extruded profile 10 is cooled, the extruded profile 10a is largely deformed in the longitudinal direction, but the cooled extruded profile 10a conveyed by the conveying force of the conveying section 11 is deformed by the stopper 17 according to the deformation.
It is corrected almost straight by hitting each one in sequence.

等の歪みを矯正する。The stopper 17 is rotated to the non-stop position to convey the substantially straight cooled extruded shape member 10c to the tension straightening machine 7, and one longitudinal end 10b thereof is gripped by the fixed gripping portion 7a and the movable gripping portion. 7b is moved in the direction of arrow c to grip the other end 10d in the longitudinal direction, and the movable grip 7b
Is moved in a direction away from the fixed gripping portion 7a and pulled to correct distortion such as bending.

引張ることができる。At this time, the substantially straight cooling extruded profile 10c
The position of the one end portion 10b in the longitudinal direction is always constant even if there is contraction during cooling as described above, so that the fixed grip portion 7a can correctly grip. In addition, the fixed grip 7 of the tension straightening machine 7
Since the extruded shape material is substantially straight when it is conveyed to a and the movable gripping portion 7b, both longitudinal end portions of the extruded shape material can be reliably gripped near the center of the gripping portion and twisting does not occur when pulled. You can pull correctly with the amount of stretch (tensile amount).

困難となるThat is, if the stopper 17 is not provided, it is conveyed to the tension straightening machine 7 in a state of being largely deformed in the longitudinal direction, so when pulling by the tension straightening machine 7, first take up until straightened, and then pull. Since it is stretched by twisting or take-up pressure at the time of take-up, it is difficult to accurately pull it to a predetermined stretch amount.

しく把持して引張ることができる。The longitudinal end of the extruded profile conveyed by the conveying section 11 is gripped by the profile-gripping machine 12 while the extruded profile is cooled and the longitudinal end of the extruded profile is cooled. Since it is possible to always position the extruded profile constantly regardless of contraction, one end portion in the longitudinal direction becomes constant when the cooled extruded profile is conveyed to the tension straightening machine 7, and the pulling straightening machine 7 can correctly grasp and pull.
