This model is computer controlled with English Software Operating.
The automatic high-strength bolt detector (JW-500DP D) can detect, display and print the axial force, torque, and torque coefficient of the large hexagon head high-strength bolt connection pair (M16, M20, M22, M24, M27, M30). When the axial force reaches the value specified in the standard, the tester will beep and record the test data. After the device stays for 1 second, it will automatically reverse to loosen the sample. At the same time, the tester will automatically calculate the torque coefficient based on the detected axial force and torque. And automatically display; when a set of tests are completed, the detector automatically calculates the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation of N test pieces; the control system can cycle through 1000 sets of data Update storage and can read and print at any time.
In addition, the pretension of the torsion shear type bolt connection pair (M16, M20, M22, M24, M27, M30) can also be tested (optional). When the torx head is twisted, the pretension of the bolt can be recorded and used as a set of tests. After finishing, the tester automatically calculates the average pretension, standard deviation and coefficient of variation of N test pieces. The horizontal structure microcomputer-controlled high-strength bolt detector is equipped with torsion shear wrenches to realize the torsion shear function. The specifications include M16-30 six specifications of wrenches and corresponding sleeves. During the test, it is no longer loaded by the host motor, but passed Wrench loading, the equipment collects the pre-tension from time to time, records and analyzes the test results, after processing, the test results can be displayed and printed directly.
Testing Principle
The detection of steel structure large hexagon bolts is to connect two sensors through the controller to collect the axial force and torque of the sample. The two sensors bear the combined force of the sensors through the combination of mechanical structure to ensure simultaneous loading and unloading at the same time. When the set standard pre-tension value is reached, the torque coefficient under the corresponding torque is recorded and calculated; the detection of torsion shear type high-strength bolts is also connected to the axial force sensor through the controller, and the axial force of the sample is collected. When the plum blossom head is twisted When, record the tightening axial force.
8 Samples can be tested
Features:
1. The height of the main machine adopts the principle of man-machine design, and the touch operation is convenient. It adopts horizontal structure, thickened steel plate, fine grinding table, and ribbed support to ensure the rigidity of the whole machine. The motor, reducer, coupling, torsion sensor, axial tension device, etc. are on a central axis to ensure Sufficient coaxial accuracy to complete the bolt test.
2. The bolt installation test module is positioned on the linear guide rail, and the test piece is easy to install and adjust.
3. Humanized program design, one-click completion of the test process.
4. The input end uses a reducer to load at a uniform speed to ensure the uniformity, stability and speed accuracy of the transmission, and improve the authenticity of the test results.
5. The electric wrench is omitted, the test operation is convenient, and the work efficiency is high
6. The machine has the functions of parameter backup and recovery, automatic calibration, and sensor overload protection prompts.
