Claims

[Scope of utility model registration request]

(1) By passing the coil material through several sets of forming rolls,
A roll forming apparatus for forming a coil material into a desired cross-sectional shape, characterized in that a chamfering mechanism for chamfering both side edges of the coil material is disposed upstream of a first forming roll.

(2) The chamfering mechanism is such that V-shaped grooves are formed on the outer periphery of at least a pair of chamfering rolls to press against both side edges of the coil material and crush the edges, and the chamfering rolls move as the coil material m. The coil material is rotatably supported by support blocks on both sides of the coil material via upper and lower shafts so that the coil material rotates, and the support block is rotatably supported so that the coil material can be held with a predetermined force by the chamfered rolls. The roll according to claim 1, wherein the shaft is mounted on the block so as to be movable in parallel in the clamping direction, and the support block is provided with a clamping force adjustment member for moving the shaft in parallel. Molding equipment.
