Pop rivets are not new to you, but do you know the precautions for using pop rivets? Now, we will provide you with tips for using pop rivets.
Precautions for using pop rivets:
Under the action of closing pressure, if the pop rivets are bent and deformed due to instability, it will cause the ball clamping and inflexible rotation. The flexibility of rivet bending in the thickness direction is the largest, so it is only necessary to check the stability of rivet in the thickness direction. Where λ is flexibility, μ is height coefficient, I is inertia radius, and j is inertia moment of rivet in thickness direction.
When riveting for the second time, it can be regarded as the lower end is fixed, and the upper end can only be translated without rotation. Because the pull mandrel rivet is short, its flexibility is generally less than the flexibility of the corresponding material yield limit, so the rivet is a flexibility bar, so the critical stress of rivet destabilization is to check the stability of the compression bar of the rivet. It refers to the actual stable safety factor during riveting and pressing of pop rivets. It is the specified stable safety factor. Generally, it is 1.8-3.0, and the working stress of rivets. If the calculation results of ring groove rivets do not meet the above conditions, pop rivets show that the stability of rivets is insufficient when riveting, and the stability should be improved by increasing the rivet thickness s.
The above is the tips for using pop rivets provided by Xiaobian. Dongguan zhekun Hardware Technology Co., Ltd. focuses on the R & D and production of high-strength pop rivets. Its main products include pop rivets, turn around rivets, quick rivets, closed rivets, open rivets, single strand rivets, pull rivets, etc. it can provide a series of solutions from design, delivery to home and technical guidance Service, and provide riveting tools maintenance guidance.
