How to apply the pre tension force of torsion shear high-strength bolts?
1、 How to apply the pre tension force of torsion shear high-strength bolts?
There are generally several methods of application:
1. Torque control method: Use a torque wrench to tighten the bolts to reach the predetermined torque value, thereby achieving pre tension.
2. Corner control method: By controlling the relationship between torque and corner, the predetermined pre tension is achieved. This method requires the use of a professional torsion angle table for control.
3. Stretch control method: By using a stretcher to apply pre tension, the bolt is firmly stretched to achieve the predetermined pre tension. This method requires professional equipment and tools, and its use is relatively complex.
