Steel bar tensile testing machine is suitable for scientific instruments and equipment for testing metal materials, such as tension, shear, bending, etc. The whole machine looks beautiful and modern; The power part of the equipment uses a servo motor and control drive system, built-in imported gapless precision ball screw, which effectively improves the transmission efficiency and displacement accuracy, ensures the stability of the system, reduces wear and noise, and uses high stability and high precision imported force sensor, and then the line accuracy is up to 0.01%, and mMultiple sensors can be selected to achieve a wide range of test force measurements; the process uses a fully digital force, displacement and deformation three-loop control system to ensure the error accuracy limit of the entire machine is within ±0.5%.
It uses a mechanical and electrical integration design, mainly consisting of a load cell, servo driver, microprocessor, computer and color inkjet printer. The high-precision servo speed control motor can adjust a stepless testing speed. All integrated components are pluggable. The floor-standing models, as well as the modeling and painting, have fully taken into account the relevant principles of modern industrial design and ergonomics.
1. Software platform: VC programming can be run on the independent installation software under WINDOWS 98/2000/ XP systems are running.
2. Wide range of uses: various materials can be tested for tension, compression, flexure, shear, tear, peel, low cycle cycle, creep, etc.
3. Force value extension: One device can calibrate several sensors at the same time and thus extend the test range. 4. Range mode: the whole range is not divided into files and can support 0.2% to 100% of the full load of the sensor.
5.Optional Curves: Various curves such as stress-strain, force-strain, force-time, force-strain, force-time, etc. can be selected. 6. Curve comparison: The curves of a test group can be superimposed in several colors and compared.
7.Local Magnification: Each section of the test curve can be magnified and analyzed.
8. Data Editing: The test data can be edited and modified, which is flexible and applicable.
9. Auto save :DData such as test conditions and test results can be saved automatically.
10. Report format: The test report format is flexible and adaptable to different needs of different users. 11. Effective selection: It can be artificially selected whether the curve data in a group of experiments is valid or not. 12. Automatic return: The moving beam can automatically return to the test starting position. 13. Manual Control: The bar can be manually controlled to move up and down. Some features:
1. Automatic reset: The computer will automatically reset the measurement system after receiving the test start instruction.
2.Automatic return: After the automatic detection test is interrupted, the moving bar will automatically return to the home position at high speed
3. Automatic storage: test data and experimentalConditions are saved automatically to prevent data loss due to sudden power failure.
4. Testing process: testing process, measurement, display, analysis, etc.
5. Display mode: data and curves are displayed dynamically along with the test process
6.Result playback: test results can be recalled at will and data curves can be re-analyzed
7. Curve sweep: after the test is completed, the mouse can be used , to find out the force value point by point and the deformation data of the test curve, which is convenient and practical to get test data of different materials.
8. Comparison of results: Multiple test curves can be overlaid, reproduced, enlarged and displayed in different colors to analyze and compare a group of samples
9. Curve selection: tension-strain, force-time can be selected according to need, intensity-time and other curves are displayed and printeduckt;
10.Batch test: After the test is set once with the same parameters, the test of a batch of samples can be completed one by one;
11. Test report: (can be made according to customer requirements)
Tensile stress: Maximum force, Tensile strength, Elongation at break, Young's modulus, etc.
Bending: Maximum force, Bending strength, Deflection, Young's modulus, etc.
Compression : Maximum force, Compressive strength, Yield strength, Young's modulus, etc., and the test report can also be programmed and printed according to the format required by the user;
12. Border protection: with two levels of program control and mechanical protection;
13. Overload protection: automatic shutdown when the load exceeds 10% of the rated value;
Emergency shutdown: an emergency stop switch is provided to cut off the power supply to the whole machine in an emergency;
Automatic diagnosis: the system has an automatic diagnostic functionn, which regularly checks the measurement system and drive system for over-voltage, over-current, over-temperature, etc., and stop immediately if abnormal conditions occur;
14. Realize the independent operation of the host computer and microcomputer.
