Metal wire drawing bolt is a kind of metal material connector with special structure and high riveting compressive strength, which belongs to the new tightening parts. After the bolt core of the metal wire drawing rivet is pulled into the rivet body, under the effect of the special type riveting gun, the broken part of the rivet core will go into the concave groove of the rivet body in reverse, resulting in "external lock of mechanical equipment" and clamping the nail core.

Main features of metal wire drawing bolts are as follows:

The bolt riveting has high compressive strength, tensile and shear stress of regulator, and has the structure of locking mechanical equipment. Therefore, when riveting, it is far more and more tightly grasped than other types of bolts, with moisture-proof and seismic grade.

The way to check the actual effect of riveting is to select the method of cross-section observation and immediate experiment. Among the two methods, the cross-section observation of automobile copper rivet is a visual and practical way. The cross-section observation is to grid, polish and polish along the meridian plane at the riveting point after riveting, observe, accurately measure and analyze its cross-section appearance. The immediate experiment method is a way to investigate the riveting quality, but the actual operation is complicated. Because of the lack of scientific research on the connection between the cross-section appearance of the connector and the riveting quality, the cross-section observation is still carried out with the help of working experience at this stage, and the credibility of the results is not high. Therefore, it is necessary to carry out scientific research on the causes of manufacturing defects, comments on manufacturing defects and prevention of defects, so as to provide theoretical basis for the operation and inspection of riveting quality.
