Abstract

A roll bending apparatus includes: a roll pair formed by a pair of rolls disposed facing each other, the roll pair being configured to sandwich an elongated material between the rolls to perform forming on the elongated material; a slide mechanism configured to slide the roll pair in a first normal direction that is a direction normal to a conveying direction of the elongated material on a plane including the conveying direction; and a tilt mechanism configured to rotate the roll pair about a tilt axis that extends in a second normal direction that is a direction orthogonal to the conveying direction and the first normal direction. The slide mechanism further slides the roll pair to change a position of the roll pair relative to the tilt axis.

First claim

The invention claimed is:

1. A roll bending apparatus comprising:
a stand base;
a tilt axis support that is placed on the stand base and that slides relative to the stand base on a plane including a conveying direction of an elongated material in a first normal direction that is normal to the conveying direction;
a roll pair support disposed on the tilt axis support, such that the roll pair support rotates about a tilt axis that extends in a second normal direction that is orthogonal to both the conveying direction and the first normal direction; and
a roll pair that is supported on the roll pair support and that is comprised of a pair of rolls disposed facing each other, the roll pair sandwiching the elongated material between the rolls to perform forming on the elongated material, wherein:
the roll pair includes a first roll and a second roll, and
the roll bending apparatus further comprises a first roll support that supports the first roll and that is supported on the roll pair support, the first roll support sliding relative to the roll pair support in the first normal direction.

2. The roll bending apparatus according to claim 1 , further comprising a second roll support that supports the second roll and that is supported on the first roll support, the second roll support sliding in the first normal direction relative to the first roll support.

3. The roll bending apparatus according to claim 1 , further comprising forming roll parts, wherein one of the forming roll parts includes the roll pair, the forming roll parts being arranged in the conveying direction of the elongated material, wherein
at least one of the forming roll parts includes the tilt axis support and the roll pair support.

4. The roll bending apparatus according to claim 3 , wherein
each of the forming roll parts include:
a cross-sectional-shape-forming roll bending part that roll-forms an elongated plate member that is the elongated material into an elongated component having a predefined cross-sectional shape; and
a curve-forming forming roll part that forms a curve in the elongated component that is the elongated material, and

the curve-forming forming roll part is provided with the tilt axis support and the roll pair support .

5. A roll bending apparatus comprising:
a stand base;
a tilt axis support that is placed on the stand base and that slides relative to the stand base on a plane including a conveying direction of an elongated material in a first normal direction that is normal to the conveying direction;
a roll pair support disposed on the tilt axis support, such that the roll pair support rotates about a tilt axis that extends in a second normal direction that is orthogonal to both the conveying direction and the first normal direction; and
a roll pair that is supported on the roll pair support and that is comprised of a pair of rolls disposed facing each other, the roll pair sandwiching the elongated material between the rolls to perform forming on the elongated material, the pair of rolls including a first roll that includes an upper smaller-diameter portion and a lower larger-diameter portion, and a second roll that includes an upper larger-diameter portion and a lower smaller-diameter portion.

6. A roll bending apparatus comprising:
a stand base;
a tilt axis support that is placed on the stand base and that slides relative to the stand base on a plane including a conveying direction of an elongated material in a first normal direction that is normal to the conveying direction;
a roll pair support disposed on the tilt axis support, such that the roll pair support rotates about a tilt axis that extends in a second normal direction that is orthogonal to both the conveying direction and the first normal direction; and
a roll pair that is supported on the roll pair support and that is comprised of a pair of rolls disposed facing each other, the roll pair sandwiching the elongated material between the rolls to perform forming on the elongated material, the pair of rolls including a first roll and a second roll, a rotational axis of the first roll and a rotational axis of the second roll being parallel to each other during forming of the elongated material.
