Claims

[Scope of utility model registration request]

A pair of front and rear lower rolls are rotatably horizontally supported at a desired interval on the main body, and a gap is formed between the lower roll and the main body above the two lower rolls, through which the plate to be formed passes; In a bending roll machine, the upper roll is cantilevered and rotatably supported on a horizontal axis, and the upper roll is movable up and down with respect to the lower roll. A letter-shaped holding arm is disposed in a direction perpendicular to the roll axis, and this holding arm has an engaging part at one end, a holding part in the middle part that presses and holds the upper roll from above, and the other The end portion is pivoted to the main body, and the holding portion is pivotable about the pivot point between a lower position where the holding portion abuts and holds the upper roll and an upper position where it is separated from the upper roll and does not hold it. A cylinder for swinging the holding arm is provided, and the main body includes an engaging member that releasably engages the engaging portion of the holding arm when the holding arm is in the downward position. A bending roll machine characterized by being provided with an actuating member that is movable in a direction perpendicular to the moving direction and that moves the engaging member.
