The riveting process of the riveting machine

Positioning and fixing of assembly parts - making rivet holes - countersunking head sockets - removing burrs and cleaning - re fixing - inserting rivets for riveting - repairing rivets - inspecting - eliminating and replacing unqualified rivets;

1. Use a handheld riveting machine to rivet

Due to the constraints of the size and shape of the handheld riveting machine jaws, it is generally only suitable for single nail riveting of structural edge riveting seams.

The operating procedure is as follows:

(1) According to the process specifications or instructions, select the required riveting machine jaw form and riveting punch based on the structural characteristics of the product.

(2) Determine the thickness of the rivet joint interlayer using measurement and calculation methods.

(3) Install riveting punches on the fixed arm and movable arm of the handheld riveting machine respectively. When riveting flat head rivets, install the rivet head punch on the fixed arm and adjust the distance between the upper and lower punches;

(4) Use test pieces of the same thickness as the structure to rivet 1-3 rivets. After passing the quality inspection, riveting can be carried out on the product.

(5) Riveting generally adopts the positive riveting method. During riveting, the lower punch of the fixed arm of the riveting machine first contacts the rivet head and adjusts the riveting part. The outer surface should be perpendicular to the punch, and then the valve on the riveting machine is pulled for riveting.

During the riveting process, the handheld riveting machine should be flexible and the grip strength should not be too rigid, otherwise it will affect the quality of riveting.

2. Use a riveting machine to rivet

The operating procedure is as follows:

The riveting stroke device of the riveting machine is installed on the upper part of the bending arm. In order to adjust the height of the rivet head and observe the quality of the rivet head, the positive riveting method is usually used for riveting. When riveting, the rivet is inserted from bottom to top, and each time a rivet is inserted, the riveting machine completes one riveting cycle.
