[0009] Further, a plurality of long circular hole chutes for the positioning tube to slide relative to the installation seat are provided on the lower die base plate. The positioning tube is locked on the long circular hole chute by screws and nuts.

[0010] To solve the above technical problems, the technical solution adopted by the present invention is: a riveting and stamping method for the iron shell seal ring of an insert bearing, using the above-mentioned riveting and stamping die for the iron shell seal ring of an insert bearing, and comprising the following steps:

[0011] (1) Place the iron shell seal ring in the positioning groove of the lower die pad, and place the bearing that needs to install the iron shell seal ring directly above the iron shell seal ring;

[0012] (2) Fix the lower die pad on the top middle of the lower die bottom plate, and then fix the lower die pad through multiple pressing devices;

[0013] (3) Close the upper die and the lower die, and the bottom of the upper centering shaft approaches the top of the lower centering shaft;

[0014] (4) The upper die drives the seal ring pressing sleeve to press down on the bearing, so that the iron shell seal ring located in the positioning groove is riveted on the inner side wall of the outer ring of the bearing;

[0015] (5) Take out the bearing, turn the upper and lower surfaces of the bearing over, and repeat steps (1) to (4);

[0016] (6) Take out the bearing and package the finished product.

[0017] Compared with the prior art, the present invention has the following beneficial effects: The riveting and stamping die for the iron shell seal ring of the insert bearing rivets the iron shell seal ring of the bearing through the cooperation between the upper die and the lower die. The iron shell seal ring and the bearing are sequentially placed on the mounting seat, and the mounting seat is fixed by the pressing device. Finally, the bearing and the iron shell seal ring are riveted and stamped by the stamping device, with high installation accuracy and high yield. BRIEF DESCRIPTION OF THE DRAWINGS
