NKYJZ-1000E-1500E 5000NM 1000KN Computer Controlled High Strength Bolt Torque Axial Force Torsion Testing Machine
I. Equipment Overview and Technical Parameters
1.1 Main Purpose: This testing equipment is developed and produced in accordance with widely recognized national and industry standards for testing machines, including GB/T 2611-2007 General Technical Requirements for Testing Machines, JB/T 9370-2015 Technical Conditions for Torsion Testing Machines, and JJG 139-2014 Verification Regulation of Testing Machines. Additionally, it references standards such as GB/T 1231-2006 Technical Requirements for High-Strength Bolts and Nuts for Steel Structures, GB/T 16823.1-2010 Fasteners – Torque/Clamp Force Testing, GB50205-2001 Code for Acceptance of Construction Quality of Steel Structures, GB/T 32076.2-2015 Connection Assemblies for Preload High-Strength Bolted Structural Connections, EN 14399.2-2005 High-Strength Structural Bolting Assemblies for Preloading – Part 2: Suitability Test for Preloading, ASTM A325M-2009 Standard Specification for Structural Bolts, Steel, Heat Treated, 830 MPa Minimum Tensile Strength (Metric), ASTM F3125/F3125M-15a Standard Specification for High-Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions, AS/NZS 1252:1996 High-Strength Bolts with Associated Nuts and Washers for Structural Engineering, and NB/T 31082-2016 High-Strength Bolt Connection Assemblies for Wind Turbine Towers.
This instrument is designed to measure and analyze the axial force, torque, and torque coefficient of high-strength bolt connection assemblies, including hexagonal and double-head types, with data visualization and printing capabilities. When the axial force reaches the preset standard value, the system emits an audible alert and records the peak test data. Following a brief 1-second delay, it automatically reverses to release the sample. The equipment then calculates and displays the torque coefficient based on the detected axial force and torque values. Upon completion of a full test set, the system automatically computes and presents the average axial force, average torque, average torque coefficient, standard deviation, and coefficient of variation for the tested samples.
