Drilling method for blind rivets



1. Drilling: Drilling is an important method for blind rivets. The main factors affecting the quality of drilling are: the geometry of the workpiece material, the cutting part of the drill, the sharpness of the blade, speed and feed rate.

(1) Determine the drill bit, cutting speed and feed amount according to the material of the workpiece;

(2) The drill should use an edge grinder as far as possible to focus on edge grinding;

(3) Generally, holes should be drilled from one side of large-thickness and high-strength parts, and thin parts should be supported by wooden strips at the same time;

(4) When drilling according to the guide hole and line on the skeleton, the hole should be drilled from the skin side first, and then the size should be drilled from the hole;

(5) When the diameter of the rivet is greater than 4mm, a small hole should be drilled first, and then the hole should be enlarged with a drill bit. The diameter of the hole is usually 0.6 to 0.8 times the diameter of the rivet;

(6) For the dimple part, drill and dent the same diameter as the first guide pin, and then expand the size according to the socket hole;

(7) Use a drill bit or special tool with a diameter larger than 1200-1600 angle rivet holes to remove burrs.

2. Punch: It is difficult to ensure the quality and low drilling efficiency with drilling punching, such as thin stainless steel parts on the drill. But some sensitive materials, such as LC4, are not suitable for stamping. Manual punching into punching pliers, portable punching machines, punching machines and other tabletop punching equipment.


3. Hole reaming: (1) When the thickness of the intermediate layer is greater than 15 mm and the hole diameter is greater than 6 mm, the hole reaming process shall be applied, and the surface roughness of the hole shall not be greater than 1.6 μm. Blind rivets (2) should be reamed with air drill or artificially.
