In modern buildings such as steel structure engineering, bridge construction, wind turbine towers, high-speed railways, and large venues, high-strength bolt connections serve as key fasteners, and their mechanical performance indicators such as axial force, torque, and torque coefficient directly affect the safety and reliability of engineering structures. As a professional manufacturer in the field of material mechanics performance testing in China, Jinan Xinguang Testing Machine Manufacturing Co., Ltd. (hereinafter referred to as "Xinguang") has officially launched the XGLS-800D microcomputer controlled high-strength bolt tester with profound technical accumulation, providing high-precision and fully automatic testing solutions for the production inspection, quality certification, and engineering acceptance of high-strength bolt connection pairs.
The torque coefficient and axial force of high-strength bolted connections are the core parameters for measuring their fastening quality, which directly affect the reliability of steel structure connections. The Xinguang XGLS-800D high-strength bolt tester strictly follows the new national standard design and has the following outstanding advantages:
1、 Ultra large tonnage carrying capacity, full specification coverage
In response to the testing requirements of high-strength bolts of different specifications, the XGLS-800D high-strength bolt tester can achieve an axial force test force of 800kN and a torque test force of 5000N · m. It can perform axial force and torque (or torque coefficient) testing on the full range of specifications of large hexagonal high-strength bolt connection pairs M12 to M36, covering the testing requirements from conventional to ultra large specifications.
2、 Horizontal human-machine design, safe and convenient operation
The equipment host adopts a horizontal structure, which follows the principles of ergonomics design. The testing process is safe and reliable, and the operation is convenient. The bolt twist pull installation test module is installed on a linear guide rail, making it easy to install and adjust the test piece, greatly improving testing efficiency.
3、 Foolish software design, one click completion of experiments
The measurement and control software independently developed by Xinguang adopts a foolproof operation interface, and the experimental process can be completed with one click, greatly reducing the training cost of operators. The software has functions such as setting, detection, calibration, verification, query, time setting, digital peak holding, unloading, upper and lower limit traffic light display, alarm prompt, automatic calculation and printing of raw data and detection results.
4、 The reducer is loaded at a constant speed, resulting in stable and reliable results
The input end adopts a reducer for uniform loading, greatly improving the consistency, repeatability, and authenticity of experimental results. The equipment is automatically loaded by a cycloidal pinwheel reducer, guided by a linear guide rail, and has a fully Chinese operating interface to achieve automated detection throughout the entire process.
5、 Humanized design, details showcase quality
The lower end of the host body is equipped with a toolbox, making it more convenient for test operators to work. The equipment structure design is reasonable and the overall layout is compact, which not only meets the professional testing needs of the laboratory, but also suitable for on-site sampling scenarios.
The Xinguang XGLS-800D high-strength bolt tester fully complies with the following national standards and industry specifications:
-GB/T1231 "High strength large hexagon head bolts, large hexagon nuts, and washers for steel structures"
-GB/T3632 "Twisted shear high-strength bolt connections for steel structures"
-GB/T50205 "Code for Acceptance of Construction Quality of Steel Structures"
-GB/T10128 "Method for room temperature torsion test of metals"
The product is widely used in the following fields:
-Steel structure engineering: random inspection and re inspection of bolt connection pairs at the steel structure installation site
-Bridge construction: torque coefficient detection of high-strength bolt connection pairs for large-span bridges
-Wind turbine tower: Verification of axial force and torque coefficient of flange connection bolts for wind turbine tower
-High speed railway: Mechanical performance testing of high-speed railway track fastening system and bridge support bolts
-Quality inspection agency: Third party testing and certification agency carries out quality supervision and inspection of bolt products
-Bolt manufacturing enterprises: bolt factory inspection, new product research and development, and process verification
-Engineering Supervision: Supervision Sampling and Quality Acceptance of Steel Structure Construction Process
