The present invention relates to a blind rivet that is easy to work simultaneously. In particular, the present invention is an automatic self-drilling riveting power tool that can be drilled and riveted without a separate drilling machine or riveting tool by integrally attaching a high-strength drill blade for drilling fastening holes in two or more plates in front of the blind rivets Self-drilling into two or more plates simultaneously and inserting blind rivets, then drawing the rivet seam and expanding the expansion cylinder to join two or more plates and remove the rivet seam in one process A blind rivet that is easy to work with.
In general, rivet refers to integrally fastening at least two or more plates (connectors) such as plates, sections, or mechanical and mechanical devices, and various workpieces. Next, the locking jaw, or head, is formed by a hammer or a mechanical device, and the head is formed and fixed. Since these operations are performed by hand, the connection process is complicated and the defect rate depends largely on the skill of the operator.
Therefore, in recent years, various types of rivets have been developed to enable simple and efficient riveting operations, and blind rivets are used for this purpose.
The blind rivet is composed of a rivet shim consisting of a head, a rivet body and a cutting groove, and an expansion cylindrical body coupled to the rivet shim and consisting of an expansion cylinder and a flange, for fastening the blind rivet to two or more plates. Drill a hole, insert the head of the blind rivet into the fastening hole, and then use a separate tool to pull the rivet seam so that the end of the expansion cylinder is extended, and the rivet seam and the rivet body start from the cutting groove. The two plates are integrally combined while being separated.
As described above, in the process of riveting two or more plates using blind rivets, a separate tool for separating the rivet core from the rivet body should be used. Of course, it is natural that an operator must drill a fastening hole in two or more plates before that.
That is, two or more plates can be easily riveted by using a blind rivet, but there is a problem in that a work of drilling a fastening hole for fastening the blind rivet and removing a rivet core from the blind rivet must be performed separately.
The present invention for solving the conventional problems as described above, by integrally attaching a high-strength drill blade that can puncture the fastening hole to two or more plates in front of the blind rivets drilling and riveting without a separate drilling machine or riveting tool Self-drilling riveting power tool is available for self-drilling, inserting blind rivets on two or more plates simultaneously, and then extending the expansion cylinder while drawing the rivet seams to join two or more plates together and remove the rivet seams. Its purpose is to allow it to be performed in one process.
In addition, the present invention, unlike the prior art that requires the use of two or more work tools by using a single tool by riveting the blind rivets on two or more plates using an automatic self-drilling riveting power tool capable of drilling and riveting at the same time The goal is to maximize work efficiency and reduce costs by completing work in one process.
Simultaneous operation of the blind rivet according to the present invention for achieving the above object is an expansion cylinder having a hollow part formed therein and a flange formed at one end thereof, and a rivet body and a drill blade connecting part opposite to the flange. In the blind rivets, which are easily coupled to the hollow portion of the expansion cylinder including a rivet shim having a rivet seam separating cut groove formed at a predetermined distance from the rivet body and the drill blade connecting portion, the rivet body and the drill blade It is characterized in that the high-strength drill blade is attached to the front of the connecting portion for drilling two or more plates.
The high strength drill blade may be made of high strength carbon steel or alloy steel and the like having a strength enough to penetrate two or more plates for joining.
A mild steel body joint fixing groove is formed in the upper portion of the rivet body and the drill blade connecting portion, and a high strength drill portion bonding fixing protrusion is formed in the bottom of the high strength drill blade, thereby fixing the soft steel body bonding of the rivet body and the drill blade connecting portion. The rivet body and the drill blade connecting portion and the high-strength drill blade are integrally formed by the pressure or high voltage applied to the rivet body and the side of the drill blade connecting portion in a state where the high strength drill part joining fixing projection of the high strength drill blade is inserted into the groove. It can be joined by uneven joining or resistance welding.
A protrusion may be formed to increase the frictional force on the outer circumferential surface of the rivet shim so as to transmit the rotational force of the automatic self drilling riveting power tool to the high strength drill blade.
The rivet shim may be made of a polygonal pillar to transmit the rotational force of the automatic self drilling riveting power tool to the high strength drill blade.
Hereinafter, the present invention will be described in detail.

Therefore, according to the present invention, when joining two or more plates to join a thin plate and a non-ferrous metal sheet or a resin type plate that is difficult to weld welding, blind rivet bonding is performed, the operation for the blind rivet joining separate drilling Using a machine to drill the rivets into two or more plates, insert the blind rivets and then alternately use separate hand drilling tools or different types of riveting machines. Unlike the prior art, which has problems such as deterioration of work efficiency since all the separate tools must be carried, the present invention integrally attaches a high-strength drill blade capable of drilling a fastening hole in two or more plates in front of the blind rivet. This eliminates the need for a separate drilling machine or riveting tool Self-drilling riveting power tool that enables simultaneous drilling and riveting.Self-drilling and blind rivet insertion are simultaneously performed on two or more plates.At the same time, the expansion cylinder is extended while drawing the rivet seam to join two or more plates together. And the work of removing the rivet seam can be performed in one process.
Furthermore, the present invention provides a single tool by riveting blind rivets on two or more plates using an automatic self-drilling riveting power tool, which is capable of drilling and riveting at the same time, unlike the prior art, which requires the use of two or more work tools. Work can be completed in one process by maximizing work efficiency and reducing costs.
