WSC-300 microcomputer controlled relaxation testing machine in the design process, the absorption of Germany, Italy and other famous relaxation testing machine company's design philosophy and structural characteristics, and based rebar relaxation test developed by the relevant national standards, dedicated to relaxation test strand, galvanized steel wire and rebar and other materials. is designed for rebar fabrication, manufacturers use design. This series of testing machine is mainly used for rebar relaxation tests can detect rebar and other metal wire uniaxial stretching relaxation strength and other characteristics can be widely used in quality control departments, construction units, steel hinge wire and steel production enterprises, is the new test equipment mechanical testing of modern architecture. meet GB / T20065-2006 (prestressed concrete rebar), GB / T10120-1996 (metal stress relaxation test method) Test machine host and aids the design draws on Shimadzu's advanced technology, beautiful appearance, convenient operation and reliable performance. The computer system via the controller, After the servo motor rotation speed control system, the deceleration system deceleration after moving through the precision screw driving beam Vice-forward, backward, complete relaxation of the mechanical properties of test samples, no pollution, low noise, high efficiency, has a very wide speed range and beam moving distance, has a very broad application prospects. It is widely used in metal material tests and analysis of building materials, aerospace, machinery manufacturing and other industries, is the quality inspection departments ideal test equipment.
Test machine host using horizontal structure, small footprint, heated relaxation test requirements and vibration-free conditions easily met. The machine uses speed and high precision, stable performance digital servo speed control system and servo motor as the drive system, controller as the core control system to WINDOWS operating interface control and data processing software, test force, test force peak, beam displacement and deformation test and test curve screen display, all test operations can be automated through the mouse on the computer completed a good ergonomic design makes it easier to test operation.

Third, the main functions and features:
1.1 The machine uses a horizontal structure
1.2 speed control system with servo motor and speed controller, stable and reliable, overcurrent, overvoltage, overload protection device. Speed range up to 0.001-25 mm / min.
1.3 Transmission part adopts arc timing belt, Precision Ball Screw drive, smooth transmission, low noise, high transmission efficiency.
2, control systems, operating software and data processing system
2.1 computer control system, high integration, stable performance, and easy to adjust. You can collect data in real time to experiment, to test real-time dynamic display characteristic curves, test data files can be saved manner Access common database to facilitate the realization of customers resource sharing and network management, as well as re-analysis of the user.
2.2 Protection: The machine has software and mechanical two limit protection, automatic shutdown proportion exceeds the maximum load can be dynamically set; overcurrent, overvoltage, overload and other protection functions.
2.3 Batch tests can be achieved at different levels show the curve, the curve automatically follow.
2.4 The software enables the speed of the user-defined settings, adjust the speed of the computer may also be highly accurate speed calibration at any time to adjust the speed gear and coding.
2.5 Monitoring the testing process: for a variety of parameters during the test of the test force, displacement, curves can achieve real-time display.
2.6 Results reproducing function: the coexistence of test operation is completed late, re-analysis can be based on user needs to open and test data at any time later.
2.7-by-point curve traversal function: force and deformation values by clicking the mouse on the curve, in order to achieve the various parameters of each point.
2.8 PC machine to achieve a closed-loop control, and process control test process control mode, you can switch between the various control no impact on how the computer auto-complete test process control, data acquisition, display and storage (main parameters: test force, relaxation power, or logarithmic relaxation rate relaxation rate), after completion of the test data can be analyzed and processed, and print out the test curve and test report required by the user can choose a variety of test requirements of the standard curve (or force may draw the remaining test logarithm of the remaining force, relaxation force or logarithmic relaxation force, relaxation rate or logarithmic relaxation rate, temperature, etc. with time or logarithmic time curve).
3. Computer software is based on Windows98 / Windows2000 / Windows XP platform, the interface is beautiful, easy to operate; test force, deformation meter display using the configuration display, very eye-catching; embedded database for easy data Historical and networking requirements; reports using templates mode, the user simply training to master the entire software package is strong, easy to operate, fully functional; with a standard test program, press the shortcut key, you can test the system in accordance with the standard requirements in 3-5 minutes steel stranding nominal load most vigorously for 70% or 80%, to keep within 1 minute automatically starts recording test data reaches the set time automatically terminate the test. Test curve with the theoretical curve fitting correlation coefficient of more than 99%, so the computer can In the experimental data within 100 hours 1000 hours test results calculated to be 1000 hours of continuous testing, reducing the time of the actual experiment.
