hydraulic torque wrench chart is the fastening bolts, high-strength bolts can be classified into sets of torshear type and two types: large
Hexagon, national standard sets of torshear type high strength bolt M16, M20, M22, M24, four, now also has non-GB M27, M30, two;GB large Hexagon bolt M16, M20, M22, M24, M27, M30, and so on.First for hydraulic torque wrench manufacturers bolt fastening
tightening final tightening, and each step requires a stringent torque requirements.Beginning of big hexagonal high-strength bolts tight and tight end must use a torque wrench.
① the right setting calibration of torque wrenches setting values.When the set torque wrench set value, should take fully into account the parts
of interaction between the components of the Assembly process, parts flying and ground force change parts material caused by different final torque changes, the actual situation, to set a reasonable value.Set the torque wrench
setting value is mainly as follows:
② for mechanical flange spreaders mutation, drift, can develop a reasonable calibration cycle, find such inaccurate torque wrench, repaired, adjusted to avoid inaccurate torque wrench into the production
site.Some change is great, easy alignment of torque wrenches to take every day check or get the metering Chamber repair solutions, ensuring the accuracy of the torque wrench.Wuling company through torque wrench 2 times per
week every week, week school pass rate from the lowest to the highest 50% of 100% and stable 95% above."We must first sharpen his tools", we know the torque monitor the quality of the entire process, to improve quality
control of torque, also needs to improve the quality of the tools such as SPC (statistical process control), the PDCA (plan-do-check-Act).By repeatedly implemented, torque quality will achieve the desired objectives.
dial indicating torque wrenches also known as Torque Wrenches, torque wrench or torque wrench, is a kind of wrench, generally divided into two types of torque
wrenches and hand torque wrench.Low Profile Hydraulic Torque Wrench is the product of force and distance, when fastening screws threaded fasteners such as bolts and nuts need to control the torque exerted, to ensure that the threaded fastening torque
havoc from a thread, so use a torque wrench to operate.First, set a maximum torque required, when the applied torque reaches the set value, the wrench will issue a "Kata" sound or wrench connection bend angle, which
representatives have been tightened to stop afterburner.
hydraulic torque wrench chart after using for a long time, because the working environment is not ideal, dust, moisture and
other internal parts sedimentation causes a torque wrench, calibration of torque wrenches use frequently wear of internal parts, causing a torque wrench indication of instability.Thus, regular maintenance torque wrench, torque wrench for operation
is helpful.
1. use dial indicating torque wrenches to take into account the following factors
Torque wrench selection should be based on the torque
value, set the torque value should be kept to a torque wrench
Use 1/2~2/3.
Space in the context of the effective length of the high strength bolt torque coefficient calibrator.
Meet above 2 points of, should selection weight light of torque wrench,
reduced workers of intensity for example: now has a operation space sufficient of station need using set value for 80Nm of set value type ratchet head torque wrench, from East daily with torque wrench information (see schedule)
in the, we see can with have torque wrench has QSP100N, and QSP140N, and QSP200N 3 species, which QSP140N, it than QSP100N long, set value in using range of 1/2~2/ 3, weight lighter than QSP200N.Which should ideally be QSP140N
