What are the basic knowledge of dial torque wrench


Release Time:

Jul 11,2020

Dial torque wrench is also called dial torque wrench or dial torque wrench. Torque is the product of force and interval. When tightening threaded fasteners such as screws, bolts and nuts, the torque applied by the control is very small to ensure that the threads are tightened and the threads are not damaged due to excessive torque, so a torque wrench is used to operate. Dial-type torque wrench uses a pointer to intuitively indicate the torque value of the tested nut, bolt and other fasteners on the dial, and recalls the torque value. Dial-type torque wrenches are well-done with "Baoken" dial-type torque wrenches, etc. 1. Instructions before application: A. Rotate the case or the knob on the case to drive

Dial torque wrench is also called dial torque wrench or dial torque wrench. Torque is the product of force and interval.

Dial-type torque wrench uses a pointer to intuitively indicate the torque value of the tested nut, bolt and other fasteners on the dial, and recalls the torque value. Dial-type torque wrenches are well-done with "Baoken" dial-type torque wrenches, etc.
1. Instructions before application:
A, rotating the case or the knob on the case can drive the pointer to rotate, the pointer is the memory pointer, called the forced pointer or the driven pointer; and the movement of the pointer is the working pointer, also known as the active pointer.
B, the use of this product should be based on the strength of the fasteners and torque value requirements to choose the appropriate range of specifications and models, should not exceed the scope of use.



2, before use, must first adjust the zero:
(1), right-hand use: clockwise rotation of the knob on the cover of the table, so that the memory pointer and active pointer point to the zero point of the dial line.
(2) When using left-hand rotation: Rotate the knob of the watch cover counterclockwise to make the memory pointer close to the active pointer, and the active pointer points to the zero-position engraved line of the dial.
3. When using:
Butt the square tenon of the pointer wrench with the fastener (it can be directly butted or butted through the adapter sleeve according to requirements), and then apply the wringing force slowly and steadily until the pointer points to the required torque value.
4. After application:
After the application of force is stopped, the active pointer actively returns to the zero position under the action of the elastic element and the torsion spring of the movement, and the recall pointer still stays on the indicated scale, and the torque value is accurately read. Rotate the knob on the table cover to make the memory pointer return to zero for the next application.
