At present, there are many things in the production process need to use riveting, riveting process, hydraulic riveter is more popular riveting machine, the machine through the hydraulic system to Mancheng District riveting work. Recently, some customers reported that the machine cracked after riveting. As a professional rivet maker, Tenroku industries explains the reasons for this.
1. Riveting material. Not all materials can be used for riveting. Some materials, because of their physical properties, are brittle and not plastic enough, so that when riveting, the material is very easy to crack or even crack. 2. Rivet quality problem. If the quality of the rivets used is not up to standard, it is also very easy to appear in the riveting quality is not good or crack. There are some hollow rivet hole is not in the center, the thickness of the entire rivet is not uniform, so in the riveting, the force will be uneven rivets, it is easy to crack. 3, hydraulic riveting machine adjustment problem. In the operating rules of the hydraulic riveting machine, there is no alignment with the center of rotation of the machine and the center of Rivet of the fixture, and there is deviation, which leads to the unbalanced force when riveting, when the riveting pressure on one side is small and the riveting pressure on the other side is large, finally the riveting crack appears. 4, riveting head assembly damage. Failure of the hydraulic riveter will affect the quality of the riveting, for example, the riveting head of the riveting machine assembly bearing wear, aging, damage and other conditions, then the rivets and riveting head friction will occur during riveting, causing cracks to appear during riveting.
