Precautions for use of preset torque wrench:


Release Time:

Apr 01,2021

Torque wrench is a special thing that closely controls the locking torque of bolts and nuts. It should be used correctly according to the following requirements: ⑴ It is not possible to use a preset torque wrench to remove bolts or nuts. ⑵ It is strictly prohibited to add a sleeve extension arm at the end of the torque wrench to prevent damage to the torque board. (3) Adjust the required torque according to the requirements, and make it clear that the adjustment mechanism can only be used if it is in a confirmed condition. (4) When using a torque wrench, load it evenly and slowly, and do not jerk and press it to avoid overload and cause output torque misalignment. After the preset torque is reached, the loading shall be stopped. (5) End of operation of preset torque wrench,

Torque wrenchIt is a special thing that tightly controls the locking torque of bolts and nuts., should be in accordance with the following requirements:
⑴ Preset torque cannot be appliedWrenchRemove the bolt or nut.
⑵ No torqueWrenchThe sleeve extension arm is attached to the end to prevent damage to the torsion plate.
(3) Adjust the required torque according to the requirements, and make it clear that the adjustment mechanism can only be used if it is in a confirmed condition.
(4) Apply torqueWrenchIt should be loaded evenly and slowly, and must not be pulled and pressed violently to avoid overload and output torque misalignment. After the preset torque is reached, the loading shall be stopped.
(5) PresetTorque wrenchAt the end of the application, it should be adjusted to the minimum torque to fully relax the force measuring tension spring to extend its livelihood.
(6) Water shall be prevented from intruding into the preset torsion plate to prevent parts from rusting.
(7) The chosenTorque wrenchThe opening standard of the board must be consistent with the standard of bolts or nuts. If the board opening is too large, it is easy to slip off and damage the hexagon of the screw. In the repair of imported cars, attention should be given to the selection of the board metric and inch system. The selection criteria for all kinds of boards are generally the sleeve board, followed by the plum blossom board, the opening board again, and finally the movable board.
(8) In order to avoid damage and slippage of the board, the pulling force should be on the thicker side of the opening. This should be especially careful for movable boards with greater stress to prevent the opening from showing an "eight" shape and damaging the nut and the board.
  ( 9)Torque wrenchIt is planned according to the strength of human hands. When encountering tight ribbed parts, you cannot hammer the board. Except for the sleeve board, other boards cannot be fitted with force-applying rods to prevent damage to the board or ribbed connectors.
(10) When the torque board is used, when you hear a "pop" sound, it is the most suitable moment.
Remarks:
1. Use: The torsion plate is something that rotates a bolt or nut.
2. Use: Pull force should be used when turning the torsion board, which is extremely dangerous when pushing and turning the board.
3. Torque plate can be used to tighten bolts, bolts should be cleaned and lubricated before tightening.
4. Use the torque plate to tighten the bolts, when the force should be balanced, do not use the impact force.
