Description

[0001] The present invention relates to a punching device of a c-type steel,

The present invention relates to a C-shaped steel punching apparatus, and more particularly to a C-shaped steel punching apparatus capable of drilling holes having various positions and shapes with respect to C-shaped steel.

Generally, a section steel is a general term of rod-shaped rolled materials having various sectional shapes, and is used for a steel structure.

The molten steel is injected into the shape of a footstep to form a steel ingot, the impurities are removed, and the steel is densified. The steel is then reheated in a furnace and rolled on a rolling mill.

It can be classified into the following types depending on the cross-sectional shape: isosceles a-shape, unequal-size a-shape, H-shape, I-shape, c-shape, Z-shape, T-shape and C-shape.

C-shape steel is combined with panel to be used for interior decoration and construction, mainly used for wall partitions.

Such C-shaped steel is generally formed by using a rolling tool assembly (forming roll) to form a flat plate-like steel plate so as to have a "C" cross-sectional shape, and then cut to a desired length through a cutting device.

However, when the C-shaped steel is used as a wall partition, holes are drilled in the end portion of the C-shaped steel so that connection with other frames can be smoothly performed. In the conventional molding apparatus, a punching device for perforating holes is not involved, The steel plate material is formed into a "C" cross-sectional shape, and then only the process of cutting the steel plate material is performed. Thus, the operator drills a hole in the end portion of the C-shaped steel directly in the field, .

On the other hand, in Korean Patent Laid-Open No. 10-2011-0130008 (entitled "C-shaped forming device"), a punching unit is additionally provided between a roll forming unit and a cutting unit, and a C -Shaped steel forming apparatus in which a hole is drilled in an end portion of a section steel and then a C-section steel in which a hole is perforated is cut to a desired length is disclosed. However, the punch tool is also provided at the center of the wide portion of the C- When drilling holes at a position spaced from the center of the narrow or wide part of the C-section steel, the operator drills holes in the C-section steel directly to install the hole. There is a problem coming.
