How to choose a Dalian bolt tightening machine? Comparison of torque and accuracy

In automated assembly production lines, bolt tightening machines are the core equipment to ensure product quality. Faced with different models and control methods of tightening machines, many companies are easily confused when choosing. In fact, by grasping the two core indicators of torque range and control accuracy, one can quickly select the appropriate equipment for adaptation.

Choose one, first clarify the torque requirement. The tightening torque corresponding to bolts of different industries and specifications varies greatly. Small electronic and household appliance assemblies often use small torque tightening machines, which have a small torque range and high precision requirements; Automotive assemblies, construction machinery, and steel structure assembly require high torque models with stable torque output and strong load-bearing capacity. If the torque range is selected to be small, there may be problems such as insufficient tightening and low efficiency; Excessive torque can easily cause bolt slippage and workpiece deformation.

Compare the tightening accuracy. Ordinary tightening machines are mostly open-loop controlled, with large torque errors, and are only suitable for general scenarios with low assembly requirements. The servo electric tightening machine adopts closed-loop control, combined with high-precision sensors, which can achieve dual monitoring of torque and angle, with higher accuracy and better consistency, effectively avoiding quality hazards such as missed, over, and under tightening.

In addition, it is necessary to consider the production scenario comprehensively. For industries with high demand for high-precision assembly and quality traceability, servo high-precision tightening machines are preferred; For cost sensitive and low assembly requirements scenarios, economical ordinary tightening machines can be selected. At the same time, the stability, data recording function, and after-sales maintenance of the equipment also directly affect long-term usage costs.

In summary, choosing a Dalian bolt tightening machine is not about being expensive, but about matching it. Based on torque and with precision as the core, combined with our own process requirements, we can select efficient, reliable, and cost-effective tightening equipment.
