Description

High stiffness light-weight beam and its molding device and manufacturing method

The present invention relates to a high-stiffness lightweight beam, a molding apparatus and a manufacturing method thereof, and more particularly, to form a workpiece formed by forming a reinforcing inclined surface and a reinforcing vertical surface between the upper wing and the lower wing by forming a coil to supply a coil. After processing through the plastic working method, which is press mold processing to form B, joining type A and B on both sides, and joining rivet joints on both sides, and in the press line to process the important position required for rigidity to improve the rigidity of the combined reinforced lightweight beam. It is automatically supplied and processed by sequentially feeding and supplying presses installed at regular intervals to automatically produce blanking, piercing, plastic processing burring, plastic processing embossing, plastic processing bead, banding, etc. Light weight beam is transferred automatically and precisely through When assembled, the truss structure is formed at regular intervals in the center of the beam, and the present invention relates to a high rigidity lightweight beam, a molding apparatus, and a manufacturing method for improving the bending load rigidity and the torsional moment rigidity of the lightweight beam.

The light beam is mainly of the same kind as hard steel, and refers to a rolling agent that is bent to have various cross-sectional shapes, and is mainly used as a light weight in steel frame structures, such as a fixed frame of an inner wall of a building.

Among the light beams, the C-shaped steel has a relatively wide width and an upper surface formed in a planar shape, and

Both side surfaces of the upper surface are bent to protrude to a predetermined width, and bent wings are protruded inward from the lower side of the both side surfaces. Such a seed steel is used for building interiors and structures in combination with the panels joined thereto, mainly used for partitions of walls.

However, the conventional C-shaped steel is weak in durability in the form of a simple "c", and there is a risk of defects, such as being bent inward and outward by the weight and external impact of the panel joined after installation on the building exterior wall.

In addition, the conventional C-shaped steel may not be roll-formed because processing of various shapes such as holes, beads, embossing, and banding to improve the strength thereof may cause a failure in roll forming. Existing C-shaped steel is supplied by a coil to form a C-shaped steel by roll forming, and then cut to a predetermined length (about 10 to 15 meters) to be completed.

On the other hand, the conventional "H" shaped light beam is supplied in each direction so that the coil forms an "H" shape in three directions in the process of producing the coil supply, both sides of the flange where the coils supplied in each direction meet each other It is automatically formed by installing a welding machine in the unit so as to be integrated by welding.

However, since the conventional "H" type light beam is formed by welding while supplying coils having different thicknesses, the production time is long, and the thick beam is used to increase the performance against external stiffness. The disadvantage of high production cost by using material and thin material is that it has the disadvantage of inferior rigidity. In addition, it is necessary to form new holes in order to combine with other parts by using light beam. Since the stiffness is not satisfied and it is a defect that cannot be spotlighted as a structural beam, there is a need for a lightweight, high rigidity and a lightweight beam that can reduce raw materials, but there is no alternative yet. to be.
