The contact between the rivets (R) of the circular body and the inner surface of the rivet movement passage (1-2-1) to form a line contact form, whereby the rivets along the rivet movement passage (1-2-1) Promote the movement of R) more smoothly. Then, the air cylinder (A ₁ ) is installed in place on the rivet transfer guide (1-2) to achieve a sequential rivet input action to the riveting unit (1-4) when there is a change in the length specification of the rivet used The mounting configuration is made so that the position can be adjusted according to the rivet length. In another place of the transfer guide 1-2, a switch 1-6 is provided to allow manual removal of the rivet in the transfer guide 1-2 if necessary (see FIG. 4).

8 is a process diagram sequentially showing the process of processing the aluminum plate using the Xiensi router equipment with the riveting device of the present invention described above, first the base plate of the aluminum plate (M) to be processed preferably an aluminum material ( B) on top (step 1). Subsequently, the rivet holes H are formed in appropriate locations on the aluminum plate M and the base plate B at a suitable depth (step 2). Subsequently, a rivet R is inserted into each of the rivet holes H (step 3), and the upper end of the rivet R, which emerges from the aluminum plate M, is pressed and deformed, thereby making the aluminum plate M the base plate B. After completely riveting and fixing (step 4), necessary processing is performed on the aluminum plate (M). After the machining of the aluminum plate (M) is completed in this way, the riveting fixing parts for the base plate (B) of the aluminum plate (M) are dismantled using a drill (D) (step 5). The obtained aluminum sheet M is separated from the base plate B.

As can be seen from the above description, the biggest feature of the present invention is that the rivet (R) is the aluminum plate (M) and the base plate when riveting the aluminum plate (M) to be processed to the base plate (B) In the state in which it is not completely penetrated into (B) but pressed only to a partial depth of the base plate B (step 3 of FIG. 8), the upper end portion of the rivet R is squeezed by the pressing force of the upper rivet punch 1-5 only. Since the riveting fixation of the aluminum plate M to the base plate B can be achieved by the step 4) of FIG. 8, a separate lower punch or lower support is unnecessary when riveting, thereby simplifying the configuration of the device. In addition, according to the present invention, various lengths of rivets, rivet containers, rivet transfer guides, etc., depending on the thickness of the aluminum sheet M to be processed, should be provided. Rivet feed guides (1-2) and an air cylinder (A ₁₎ (A ₂₎ to the fitting structure can be used to rivet the container 1-1 and the conveyance guide (1-2), regardless of the change in length of the rivet as a general purpose By doing so, the device can be made smaller and the installation space can be saved significantly.

By making the transfer of the rivets (R) as smooth as possible, it is possible to use not only high-quality rivets but also normal-quality general market rivets, thereby completely eliminating device failures and malfunctions caused by rivet quality deviations. .

In addition, when dismantling the finished aluminum plate (M) from the base plate (B) through the above-described work process, the conventional riveting part between the aluminum plate (M) and the base plate (B) completely penetrates vertically Since the reuse of the base plate (B) was extremely limited due to the drilling hole to be dismantled by drilling, the frequent replacement and replacement of the base plate (B) was required. However, in the present invention, the drill is embedded with the rivet (R). The riveting part between the aluminum plate M and the base plate B can be dismantled by entering only a depth slightly larger than the thickness of the aluminum plate M, and the rivet R drilled at this time is placed on the base plate B. It provides the effect of filling the grooves, so the base plate (B) can be used for much longer than before, which is very efficient and economical.

Therefore, the present invention has a novel and useful feature that can simplify the configuration of the aluminum sheet processing equipment by the above-described configuration and operation, and can provide the effect of productivity and cost reduction.
