Selection method of aluminum profile fittings connection. One of the more frequently used accessories is the bolt, which can be said to be the soul of the industrial aluminum alloy profile frame structure. Because whether it is bolt with nut connection, or bolt with supporting parts connection, need to use it. Therefore, the choice of this accessory is particularly important. It is related to the security and stability of the frame structure. But often many users will encounter the situation of bolt loosening in use, which causes great security risks to the stability of the frame.
The reasons and solutions for the loosening of industrial aluminum profile bolts are as follows:
1. After tightening the aluminum profile bolt, it may loosen after working for a period of time. For example, if the equipment is installed on the frame, the vibration generated by the operation of the equipment will affect the bolts, and it is normal for the bolts to loosen over time. The solution to this situation is that the staff should check the bolts at the connection site regularly and tighten the loose bolts twice.
2. The depth of thread hole tapping teeth processed on the profile is not enough, which is one of the reasons why the bolt is not tightened, and one of the main reasons why the bolt is loosened too fast in the process of use. The solution is in the early processing in strict accordance with the standard punching tooth size and depth.
3. The screw thread on the bolt is damaged and the fastening action is reduced. In this case, the quality of the bolt itself is not up to standard, and the thread wear is large in the process of use. The solution to this situation is to choose bolts that meet the quality standards, and replace the new bolts in time when the damage is found.
