Field of the Invention The present invention relates to a banding apparatus and a forming apparatus including the same, and more particularly, to a banding apparatus and a forming apparatus including the same, which are simple in construction and can be improved in durability.

2. Description of the Related Art Generally, a forming apparatus is a facility for processing precision components. The forming apparatus includes a material supply device for supplying a material such as a strip-shaped plate material and a wire material, a press device for forming grooves or holes in a material supplied from the material supply device, And a bending device for bending the supplied material into various shapes by using punches of the punches.

Such a foaming device is widely used to produce various shapes of automobile parts, mobile phone parts, and computer parts.

Usually, the forming apparatus is provided with a supply section for supplying a strip-shaped metal plate from a winding drum, a level section for straightening the supplied metal plate, and a dimension for forming a metal plate to be supplied from the level section, A press forming a groove and / or a hole in a metal plate, a forming machine for cutting a metal plate by a plurality of punches arranged in a radial direction, and a forming machine for forming the plate.

On the other hand, products manufactured by the forming apparatus have various types and functions in various fields, and each of these products is subjected to various processes in order to perform the corresponding functions. To this end, recent multi-formers have been equipped with various functions to cope with changes in product specifications. For example, Korean Patent Laid-Open No. 10-2010-0115185 discloses a multifoaming machine in which a rolling function is fused.

The multifoaming machine to which the rolling function is fused is arranged in such a manner that a rolling machine is disposed between the regions where the pressing process and the forming process are performed and the rolling process is performed on the metal plate in conjunction with the whole process. In the case of a multi-forming machine capable of such rolling, there is an advantage that a production cost can be reduced, for example, a rolled product can be produced without using expensive rolled raw materials.

Meanwhile, since the conventional banding device has a structure for pushing out a bending material, since there are many components and the operation is performed between the respective components, problems due to loosening of the constituent parts have. Therefore, there is a demand for a banding device that can be increased in durability by having fewer components and having a simple operation mechanism.
