Abstract

PROBLEM TO BE SOLVED: To excellently form a projection and a recess for fitting, at both ends of a metallic plate by avoiding deformation at both ends, in forming a rugged face through roll forming of projected and recessed parts while the metallic plate is fed without interruption for continuous production. SOLUTION: This method of forming a siding is such that, after a recess and a projection are roll-formed on a metallic plate 1 to form a rugged face, a projected part for fitting is roll-formed on one side end and a recessed part for fitting on the other side end. In this case, in roll-forming the rugged face, both flat ends of the metallic plate 1 are held vertically between the holding rolls 5a, 5a made of an elastic rubber-like body.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal siding forming method and a metal forming apparatus, and more particularly, to a method of forming a concave and a convex in a metal plate while continuously feeding the metal plate and performing continuous production. The present invention relates to a technique for avoiding deformation (irregularity) of both ends of a metal plate when forming a concave-convex surface so that a fitting convex portion and a fitting concave portion can be favorably formed at both ends. .

[0002]

2. Description of the Related Art Conventionally, concave and convex portions are roll-formed on a metal plate vertically and horizontally to form an uneven surface, and then a fitting convex portion is formed at one end and a fitting concave portion is formed at the other end. In doing so,
The stress at the time of forming the concave and convex portions forming the concave portions and the convex portions is applied to both ends of the metal plate, and therefore, both ends of the metal plate are deformed, so-called “burrs” occur. Due to the deformation of both ends of the plate, there is a problem that it is difficult to form the fitting recesses and the fitting protrusions well thereafter.

[0003]

By the way, concave and convex portions are formed on a metal plate by pressing vertically and horizontally to form an uneven surface. Further, a fitting convex portion is formed at one end of the metal plate, and the other end is formed. There is a method of manufacturing metal siding by press-molding a fitting recess in the part, but in such a manufacturing method by press,
In addition to the same problems as above, a batch-type manufacturing method in which a metal plate is brought into a pressing device each time is required, and continuous production cannot be performed by continuously unwinding a hoop material wound with a metal plate. It is difficult to enhance the character.

[0004] The present invention has been made in view of such a problem, and a concave and convex portion is formed by rolling a concave portion and a convex portion on a metal plate while continuously feeding the metal plate to perform continuous production. In this case, it is an object to provide a metal siding molding method and a molding apparatus capable of avoiding deformation (irregularity) of both ends of a metal plate and forming a fitting projection and a fitting recess at both ends. Things.
