Ring groove rivets

Ring groove rivet is used to rive two structural parts into a whole. It consists of 2 parts: rivet and nail sleeve. The rivet consists of a nail rod and a nail sleeve. When riveting, first insert the rivet into the nail hole of the connected parts, and then Put the nail sleeve on the ring groove of the rivet working section from the other side of the connected piece, and then put the muzzle of the special tool - pneumatic ring groove rivet gun on the ring groove of the rivet clamping section, and press the muzzle against the ring groove of the rivet clamping section. The end face of the nail sleeve, and then pull the trigger on the gun. The rivet gun will tighten the nail rod of the ring groove of the rivet clamping section until it breaks. At this time, the inner wall of the nail sleeve squeezes into the ring groove of the rivet working section to form a new rivet It has the characteristics of convenient operation, high efficiency, low noise and good shock resistance, and is widely used in vehicles, ships, aviation, mechanical equipment, building structures and other fields.

Precautions for ring groove rivet operation:

(1) When riveting, the gun head should be perpendicular to the surface of the workpiece, and sufficient pressure should be applied to make the nail sleeve close to the workpiece;

(2) When riveting ring groove rivets, the power of the power part and the pulling gun head must meet the specifications and shape requirements of the rivet;

(3) The action of inserting or driving the rivet into the hole must be light and stable;

(4) When starting riveting, push the gun head of the pull gun to the end and hold the pull gun tightly;

(5) After riveting, if the rivet head is not close to the component, it is never allowed to push the rivet head against the component;

(6) When the steel ring groove nail is riveted, the pressure regulating valve of the pull gun must be adjusted to the high pressure position;

(7) When riveting the upsetting rivet ring grooved nails, pay attention to selecting the appropriate rivet bricks, otherwise the nail sleeves will not be good;

(8) Pay attention to prevent the workpiece from being bruised or scratched due to the rebound of the drawn gun when the nail rod is broken;

(9) After the hole is made, the interlayer thickness of the riveted part must be measured with an interlayer thickness gauge to select the appropriate rivet length.
