How to control the torque of the tightening machine? After reading, understand the key points of purchasing

In industrial assembly production, torque is the core standard for tightening operations. Excessive torque can cause thread slippage and tooth breakage, while insufficient torque can lead to loose parts and equipment failure, directly affecting product qualification and safety. Many enterprises have unstable assembly accuracy and high rework rates, with the core problem being inadequate torque control and the selection of unsuitable tightening equipment. To accurately control torque and choose a cost-effective tightening machine, the key points are clear at a glance.

Accurate torque control relies on the precise regulation and data loop of the equipment. At present, mainstream servo tightening machines support dual closed-loop control of torque and angle, which can set standard torque intervals in advance and monitor torque data in real time during operation. Once the threshold is exceeded, an immediate warning and shutdown will be issued to prevent over tightening and under tightening problems from the source. At the same time, the equipment has multi-level speed regulation function, which can adjust the tightening speed according to the bolt material and specifications. The soft start and slow stop operation modes can effectively avoid torque deviation caused by instantaneous impact force and adapt to precision component assembly.

When choosing a tightening machine, one should not only consider the price, but also focus on three core parameters. Firstly, the torque range needs to be selected according to the bolt standards of the production workpiece, with a margin of 10% -20% reserved to avoid accuracy degradation caused by full load operation of the equipment. Secondly, there is the precision of repeated positioning. The precision of high-quality tightening machines can be stable within ± 3%, meeting the requirements of large-scale standardized production. Then it is necessary to pay attention to the data traceability function. Devices with data storage and upload functions can record every tightening data, facilitating quality inspection and process optimization.

In addition, the selection should be based on the production scenario. Prioritize the use of multi axis fully automatic tightening machines for large-scale operations on assembly lines, as they offer higher efficiency; Non standard small parts and precision workpieces are compatible with small servo tightening machines. Only by selecting the right equipment and adjusting the parameters can the torque deviation problem be completely solved, significantly reducing rework costs and improving assembly quality.
