Description

A slot punching device for binding member panel

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plate binding member for lifting a heavy material, such as an insulation panel, which is mainly used for ship construction. More specifically, the cylindrical body of the binding member is moved outwardly using a working tool. Slot piercing device of the plate binding member that allows the perforation of the slot formed in the longitudinal direction on the body of the binding member continuously by automation equipment when the two plates are integrally formed by buckling. It is about.

Generally, as a fastening element for coupling a plurality of structures to each other, a conventional welding method or fastening bolts are mainly used for construction of bridges or steel structures, and solid rivets when manufacturing automobiles or aircrafts. And blind rivets are widely used.

The solid rivet is effective for fixing and repairing the structure, and the blind rivet is for securing two or more plates or steel beams by using a stem and a rivet shell, and the shank of a crowded place or a rivet having a limited space. It is used when a heavy load does not work, such as a place where it is difficult to access the tip and cannot bring a bucking bar.

In the case of the bolts or solid rivets, both the inside and the outside of the structure must be bound by using a tool, so that access to both sides is possible only when the fastening and fixing thereof is not easy, and the blind rivets While the ability to transfer the forces acting between each member is large, a process of temporarily joining the stem and the rivet shell must be involved.

As a technology related to a conventional fastening element as described above, Korean Registered Utility Model No. 0282962 or No. 0402100 discloses two plates by separating the head part and the shank part of the stem by using a common gun when the two plates are fastened. Blind rivets have been disclosed that allow the two parts to be tightly coupled, but in this way, even if the head portion of the stem remains on the inner surface of the rivet, the expansion range of the rivet body is not so large that the two plates are large. If a load is applied, there is a possibility that the plate may be detached from the plate, and there is a problem that the stem itself is consumed.

In addition, Korean Patent Laid-Open Publication No. 2003-0079022 discloses a structure coupling fastener capable of fastening in one direction when binding two structures using a spindle and a rivet, and preventing a micro gap between the coupling holes. Published Patent Application No. 2008-0015130 discloses a technique using a sleeve member and a mandrel to interconnect aircraft components.

However, even in this case, as in the prior art described above, part of the spindle or mandrel remains sealed in the fastening element, so that, for example, when it is intended to be used in automobile manufacturing, the wiring process can be performed without forming a separate through hole. It had no choice but to be greatly restricted in terms of use.

The Applicant has applied both plate materials by buckling the central part of the body of the binding member having an internal diameter, as in patent application 10-2009-0087447 (filed Sep. 16, 2009) in order to solve the problems of the prior art as described above.
