M16 M20 M22 M24 M27 M30 Torsional Shear Bolt Tester Axial Force Torque Coefficient Testing Machine

Product Description

Introduction

The microcomputer-controlled high-strength bolt detector (JWW-500PE) is designed and manufactured in accordance with the GB50205-2001 "Code for Acceptance of Steel Structure Engineering". The axial force, torque, torque coefficient of the system can be detected, displayed, and automatically calculated and printed. When the axial force reaches the value specified in the standard, the tester will beep and record the test data. At the same time, the tester will automatically calculate the torque coefficient according to the detected axial force and torque and display it automatically; when a set of tests are completed, the tester Automatic calculation of the average axial force, average torque, average torque coefficient, standard deviation and coefficient of variation of N test pieces; key in test number, model, grade and specification of high-strength bolts, etc.; control system can update 1000 sets of data in cycles Store and 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 torsion shear function of the horizontal structure microcomputer-controlled high-strength bolt detector is generally through the addition of torsion shear wrenches. The specifications include six wrenches of M16-30 and corresponding sleeves. During the test, it is no longer loaded by the host motor. It is loaded by a wrench, the equipment collects the pre-tension from time to time, records and analyzes the test results, after processing, it is directly printed out in the form of a test report in A4 paper format.
It has parameter backup and recovery functions, automatic calibration functions, and functions such as peak holding monitoring and sensor overload protection according to the detection requirements of high-strength bolts. In order to facilitate the user to connect with the computer, the RS232 interface is set up; the data can be transmitted to the computer, and the report can be printed out after further processing. To
2. Test 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.
