How to determine the impact frequency of an impact wrench

Impact is the application of a high level of input pulse force to a product in a relatively short period of time, which is a very complex physical process. Like random vibration, it has a continuous spectrum, but it is also a transient process and has no conditions for steady-state randomness. After impacting the product, the motion state of its mechanical system will suddenly change and produce a transient impact response. The product's response to a mechanical shock environment has the following characteristics: high-frequency oscillation, short duration, obvious initial rise time, and high levels of positive and negative peaks. The peak response to a mechanical shock can often be surrounded by an exponential function that decreases with time. So how to determine the impact frequency of the Overtone impact wrench?

Overtone impact wrenches For products with complex multimodal characteristics, overtone impact wrenches include the following two frequency response components: the external excitation environment imposed on the product during or after excitation and the forced frequency response component inherent to the product. In terms of physical concepts, the magnitude of the impact response of a product after being impacted represents the actual impact strength of the product. If the instantaneous response amplitude of the product exceeds the structural strength of the product itself, the product will be damaged. It can be seen that the damage caused by product impact is different from the damage caused by the cumulative damage effect, but it belongs to the peak damage of the ultimate stress relative to the structural strength

The FEIN impact wrench is mainly used for preliminary tightening of bolts. It is very simple to use, just align the bolts and move the power switch. Electric torsion shear wrenches are mainly used for tightening torsion shear type high-strength bolts. Its purpose is to align the bolt and turn the power switch until the torsion-shear type high-strength bolt breaks. Electric fixed torque wrenches can be used for initial tightening and tightening. It is used to adjust the torque first and then tighten the bolt. Electric angle wrenches are also primarily fixed torque wrenches, used to first adjust the angle of rotation and then tighten the bolts. An electric angle wrench is an electric wrench used to tighten bolts at the corners of steel frames.
