Description

Technical Field

[0001] The utility model belongs to the technical field of riveting processing, and in particular relates to a rapid pressing tool for riveting. Background Art

[0002] The existing rotary riveting process usually involves inserting a rivet on a riveting tool support seat, inserting the rivet into the riveting hole of the part to be riveted, and then starting the equipment to rivet the rivet on the part under the action of the downward and circumferential rolling force of the rivet head. During the riveting process, the rivet end face that fits the part to be riveted needs to be higher than the upper end face of the riveting tool support seat, otherwise a gap will appear between the rivet and the riveted part, affecting the riveting quality; however, due to the influence of gravity, one end of the part to be riveted will be skewed relative to the rivet end face, especially when the diameter of the rivet is tightly matched with the hole of the part to be riveted, the rivet will expand and block the entire hole when it is riveted, resulting in the part to be riveted not being pressed straight under the flow of the rivet material, thereby causing a poor riveting gap.
