step one, separating an aluminum plate from the aluminum plate feeding assembly 5 and pushing the aluminum plate to the aluminum plate base 13;

separating an iron sheet 01 from the iron sheet feeding assembly 4 and pushing the iron sheet 01 to the iron sheet seat 12;

thirdly, the press machine 2 drives the upper pressure head assembly 3 to do pressing movement; in the process of downward pressing, firstly, the prepressing block 32 pushes the aluminum plate seat 13 to descend, so that the aluminum plate seat 13 and the aluminum plate 02 thereon descend together, further the aluminum plate 02 is contacted with the iron sheet 01, and the convex hull on the aluminum plate 02 enters the corresponding hole position on the iron sheet 01, then, as the press machine 2 continues to press downwards, the prepressing block 32 keeps still by abutting against the aluminum plate 02, the press head seat 31 drives the press rod 33 to descend continuously, so that the lower end of the press rod 33 penetrates out of the prepressing block 32 and acts on the convex hull position on the aluminum plate 02 together with the lower ejector rod 6 to deform the same, and the riveting operation is completed;

fourthly, the press machine 2 drives the upper pressure head assembly 3 to ascend and reset;

and fifthly, pushing the riveted finished product away from the tool 1 by the blanking assembly.

Further, the fifth step specifically includes: the lifting baffle 71 descends, and the push rod 72 pushes out to push the riveted finished product away from the tool 1.

According to the automatic riveting equipment and the riveting method, the tool, the riveting device, the feeding assembly and the discharging assembly are arranged, so that the iron sheet and the aluminum plate can be fed to the tool, the pre-assembly, pre-compaction and riveting operations of the iron sheet and the aluminum plate can be completed in one pressing process of the press, the automatic discharging can be performed, the structure is compact and the size is small due to the fact that only one station is provided, the pre-assembly and riveting processes can be completed in one pressing process, and the efficiency is high.

The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
