Abstract
A conventional blind rivet tool with modified nose housing, i.e., a rivet gun with replaceable and interchangeable nosepieces, facilitates feeding and setting of multiple diameters of blind rivets with substantially shortened exposed mandrel portions extending beyond the head flange of the rivet, all while maintaining blind rivet performance and reducing total installed blind rivet costs. A rivet with a reduced exposed mandrel protrusion relative to conventional and standardized mandrels can be enabled and more easily fed through the tool.
Claims2
A riveting tool, comprising:
- a body;
- a pulling force generator for activating the riveting tool;
- a jaw assembly within the body, the jaw assembly comprising:
- a jaw case having an angled interior annular surface;
- at least two split jaws disposed against the angled interior annular surface of the jaw case for gripping mandrels of rivets inserted into the riveting tool for setting;
- and
- a plurality of removable and replaceable nosepieces for attachment to the body of the riveting tool, each nosepiece being a different size for receiving mandrels of correspondingly different diameters and comprising:
- a first end having an aperture having a distal end adapted to receive the mandrels of rivets, and a proximal end adapted to contact and hold open at least one split jaw of the at least two split jaws for insertion of the mandrels therethrough;
- a second end having an opening greater in diameter than the aperture, the second end for attachment to the body of the riveting tool;
- wherein the distance between the distal and proximal aperture ends of each of the plurality of different sizes of nosepieces is substantially the same.
