Pressing down of pressing blade 708 of pressing block 707 presses the edge of intercooler 10 that has been turned over to less than 90 degrees. To ensure that the side of the intercooler 10 can reach 90 degrees after the pressing block 707 returns to the initial state, and the rebound phenomenon is not generated.

The working principle is as follows: taking the main riveting mechanism 7 as an example, the principle of flanging riveting is as follows: the side pushing mechanism 703 drives the flanging press block mechanism 702 to rivet the intercooler 10, the injection molding housing 9 and the sealing ring 8 in the first support positioning block 701, wherein the riveting initial state is as shown in fig. 11, the second driving cylinder 715 is used as a power source to drive the push block 714 to move forward, the slider 713 and the second guide rail 712 are used as guides, force is transmitted to the flanging press block mechanism 702 through the side pushing surface 716 and the convex edge 717 of the push block 714, the support seat of the flanging press block mechanism 702 drives the press block 707 to approach the first support positioning block 701 under the pushing of the side pushing surface 716, the edge of the intercooler 10 is turned over in the horizontal movement process of the press block 707, that is, as shown in fig. 12, the press block 707 is pushed by the convex edge 717 and is matched with the hinge shaft, so that the tail end of the press block is lifted, the press knife 708 at the head end presses down, and presses the turned edge 705 of the intercooler 10 to less than 90 degrees, that is shown in fig. 13. Wherein the first roller bearing 709 and the second roller bearing 710 realize rolling friction; after riveting is completed, the turn-up press block mechanism 702 is retracted to the initial state by the return spring 711.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
