Abstract

The invention discloses a rivet mounting method. The rivet mounting method comprises the following steps that a hole opening step is carried out, specifically, a mounting hole of a rivet is formed ina thin wall; a hole turning step is carried out, specifically, the mounting hole is stretched, so that a positioning flange is generated on one side of the thin wall; and the riveting step is carriedout, specifically, the rivet is arranged in the mounting hole, the positioning flange is compressed, and the rivet is fixed to the thin wall. According to the rivet mounting method, the rivet mountingstructure and the brazing type heat exchanger for the wall-hanging furnace, the position precision and perpendicularity of the rivet are improved.

Description

technical field [0001] The invention relates to a rivet assembly process, in particular to a rivet installation method, a rivet installation structure and a brazed heat exchanger for a wall-hung furnace. Background technique [0002] In the prior art, a rivet is a fastener with a column and a head disposed at one end of the column. [0003] The outer surface of the cylinder can be provided with external threads to make riveting screws, or the inner side of the cylinder can be opened and provided with internal threads to be made into riveting nuts. [0004] The internal and external threads allow the part to be detachably attached to the rivet, while the head allows the rivet to be fixed in a non-removable manner. [0005] For thin-walled products, rivets are generally fixed by pressure welding or butt welding. [0006] However, pressure welding or butt welding can only fix the rivets on thin-walled products, and the accuracy is difficult to guarantee. Contents of the inv...
