The precision of the bolt tightening method used to achieve an accurate preload is one of the main issues with using bolted joints. A common cause of bolted joint failure is insufficient preload as a result of improper tightening. The designer needs to be aware of the primary methods for bolt tensioning services features and characteristics. A brief overview of the most common methods for tightening bolts is provided below. Note that for anything that technique is utilized to fix a bolt, the level of bolt preload dissipates is normal. It is fixed to the most famous method for controlling preload.
Easy to use
Additionally, it’s a cheap and easy way to tighten bolts. Your tool is compact, lightweight, and simple to teach others to use. Another option for speed could be pneumatic torque tools. It is precise and intricate, much like hydraulic tensioning. Nonetheless, it attains a more significant bolt load than hydraulic tensioning. As opposed to the other bolt tightening techniques, which cause torsional tension and springing back, this method acts directly on the bolt. This makes it possible to attain 90% bolt yield strength through mechanical tensioning.
Transmit lateral force
The most successive one is an unfortunate gathering. Therefore, in order to achieve the required performance for the bolted assembly, it is essential to have perfect control over the levels of tightening force and the precision with which they are achieved. Hydraulic tensioning tightening is the best way to accomplish this. Because of the screw’s elongation, it is possible to create a significant tension force for tightening bolts without torsional stress or friction, with high precision, and with excellent repeatability.
Indicating bolt tension
Injection molders continue to have safety issues with the secure mounting of molds to machine platens because larger machines have heavier molds and greater stripping forces when the clamp opens. However, doing so may be wasteful and, in certain cases, may even cause mold damage. Others have had difficulty managing the torque that operators apply a task that becomes increasingly challenging as bolt sizes increase and the torquing forces needed to tighten them rise exponentially.
Multi stage hydraulic bolt
These tools are necessary to guarantee operational efficiency and maintain joint integrity. Find out more about the advantages of our standard tensioners. One more answer for profoundly restricted conditions, where space limits exist in one aspect, for example, a breeze turbine establishment stud where the pole is near the stud, is a circularly water-driven tensioner. Hydraulic bolt tensioner rentals provide the ample surface area necessary to generate the load on two of the tensioner’s elongated sides while maintaining a low clearance on the remaining two sides.
Force retention
In addition, the system has a locking ring that engages the body, may be turned by hand when pressurized, and mechanically maintains the ram in the initial position when hydraulic pressure is not present. The system is designed to help position the liner and provide a precise axial fastening force.
