The opening size of the rivet hole is min plus 0.1max plus 0.2. The total thickness of the workpiece is generally 45%-65% of the rivet length. Try not to exceed 60%. In addition, the working length is too short. It is also very troublesome. Usually it is recommended to use 50%- 60 percent is the standard. For example, if the total thickness of 2 or more workpieces is 6mm, the optional length of the rivet should be 9.23-13.3mm. In this case, try to use the middle 12mm length.

Pneumatic blind rivet gun - just attach directly to the wind scale. Smaller sizes such as 14kg or less are also possible. Except 6.4(6) diameter. Others can pull 6.4(6), some guns can pull, But it is more expensive than foreign countries. Personally recommend that if you use it normally, try to use well-known manufacturers. There is basically no difference in appearance. But the accessories inside are very different. If you can't pull tens of thousands, there will be air leakage. Okay. Also, the chuck is easy to break. The accessories inside are also easy to break. The spare parts are cheap, but it is too troublesome to replace.

Manual blind rivet gun - no external auxiliary equipment. Just use it directly. Generally, a small amount can be considered. The disadvantage is that the efficiency is too low. The chuck is also easy to break, it is recommended to buy a good one.

Breaking force of stainless steel rivets \/ neck breaking force (bar\/kg)

The air pressure of the rivet gun should be:

The diameter of 3\/3.2 is 4.5-5.5(bar\/kg)

4 is 6-7 (bar\/kg)

The diameter of 4.8 is 7.5-8(bar\/kg)

The diameter of 6\/64 is 9-10(bar\/kg)

If the bearing capacity of the rivet gun is not considered, there is no problem with a larger pulling force. Personally, I think the bigger the better. Although 4.8 can pull down 7 bar, the performance is not as good as 8 bar. The same is true for other specifications. The above is the general method of blind rivets. I hope I can bring you some help, see you next time.
