Drum rivets are based on the structure of ordinary open rivets, with the addition of processing of local drum points on the shell and processing of the locking position of the rivet core, so as to adapt to various riveting thicknesses (thin and thick ranges), the rivet head and the rivet body are tightly wrapped and the rivet head is not easy to loosen and fall off. According to the processing method of the drum points, it can be divided into two forms: stamping type and thread rolling type.

The rivet body rod of this type of rivet is processed with multiple drum concave points or grooves, so that the rivet is quickly folded and drummed at the concave points or grooves during the riveting process, and the radial size expands rapidly, realizing clamping of different thickness ranges.

Usage scenarios

It is used in occasions with large changes in thin and thick walls, and can achieve riveting and clamping under multiple thickness conditions. It is mainly used in automotive decoration, non-metallic components, soft material components, etc.

According to the material, head shape, and drum shape, it is divided into all-steel/aluminum steel/all-aluminum/stainless steel, flat head/round head, single drum/double drum/multi-drum and other types.

Installation Method

1.1 Product installation steps

1) Select a pneumatic or battery-powered rivet gun with matching pulling force, install a nozzle with matching diameter specifications, and adjust the appropriate rivet stroke according to the installation thickness and tool manual;

2) Load the product and perform an empty pull test;

3) Perform a real rivet test on the test sheet metal, as shown in step 1 below.

4) Observe whether the clamping state of the product is normal after installation.

5) (To determine whether the installation fails, please refer to the following article – Product installation failure mode pictures)

1.2 Operation steps

Hold the product or the nozzle close to the tail of the rivet to automatically suck in the nail core and the rivet flange surface to ensure that it is close to the nozzle. Insert the tool into the installation hole in a direction perpendicular to the sheet metal plane and close to the sheet metal surface, then pull the trigger to start riveting until the nail core breaks. At this time, one riveting action ends, and then the next working cycle is carried out.
