XGLW-800D Microcomputer Controlled High Strength Bolt Tester

The XGLW-800D high-strength bolt tester is a new type of bolt torsion testing equipment independently developed by our company. This equipment mainly detects high-strength bolt connection 

pairs and can detect the axial force and torque (or torque coefficient) of large hexagonal high-strength bolt connection pairs (M16-M36).

The equipment is automatically loaded by a cycloidal pinwheel reducer, with a linear guide rail and a fully Chinese operating interface. The high-strength bolts are automatically tightened, relaxed,

 and reset controlled by a microcomputer, and the operation process is intelligently prompted, making the operation convenient and fast. When the axial force reaches the standard setting value, 

the detector will automatically record the detection data, calculate the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation of the sample

 through the computer, and display the output torque coefficient, axial force curve, torque curve, etc. It also has functions such as parameter setting, calibration, data report printing and output, 

and query.

Relevant standards

GB/T 10128 Test Method for Room Temperature Torsion of Metals

GB/T 1231 High strength large hexagon head bolts, large hexagon nuts, washers for steel structures

GB/T 3632 High strength bolted connections with torsional shear type for steel structures

structural characteristics

The height of the host adopts a horizontal structure based on human-machine design principles, ensuring safe testing and easy operation.

The bolt twist pull installation test module is installed on the linear guide rail, and the installation and adjustment of the test piece are convenient.

Foolish software design, the experimental process can be completed with just one click.

The lower end of the host body is equipped with a toolbox, making it more convenient for test operators to work.                                                   

The input end adopts a reducer for uniform loading, greatly improving the consistency, repeatability, and authenticity of experimental results.
