　First, product overview:

WEW-L type microcomputer display significant strand testing machine mainly includes WEW-600L and WEW-1000L two models, dedicated to test on mechanical properties of prestressed steel strand, the machine is equipped with Lenovo computer, Hewlett Packard printers, large scale from electronic extensometer, photoelectric encoder and full-featured universal test software, can be very convenient to complete the function test; the other with steel strand special lengthening jaw to ensure the specimen fracture. So as to further improve the test success rate. Test results can query and print (force displacement, force - deformation, the stress and displacement, stress and strain, stress, deformation time) six curves and experimental data, with self checking function of the software, can self fault diagnosis, Cheung see software. The tensile strength of steel strand, the specified non proportional extension strength, elastic modulus, elongation and other mechanical properties were measured. Is an industrial and mining enterprises, scientific research institutes, colleges and universities, engineering quality supervision station and other departments of the ideal test equipment.

Second, program description:

1, host

The host adopts the cylinder under the host, the stretching space is located at the top of the host, and the compression test space is located between the main beam and the working platform.

2, transmission system

Under the beam lifting motor through reducer, chain drive, screw pair drive, to achieve the adjustment of tension, compression space.

3, hydraulic system

Screen WEW-600L/1000L significant testing machine for steel strand in the tank of oil through the oil filtering net is sucked into the pump, the oil pump oil pipe sent to send the oil valve, when the oil feed handwheel closes, due to the oil pressure and the piston push, oil from the back of the oil flows back to the tank, when the oil feeding the handwheel to open, fluid through tubing into working cylinder, by pressure tubing through the oil return valve body flows back to the tank.

4, control system

4.1 function profile

4.2 software description

4.2.1, main interface set multi functions in one, the main program interface includes: system menu, toolbar, showing the value display panel, speed display panel, test parameters, test process zone, multigraph curve area, the results of treatment of area and test information area.

4.2.2, curve drawing: software system provides a wealth of test curves show. Such as force displacement curve, force deformation curve, stress displacement curve, stress deformation curve, force time curve, deformation time curve.

4.2.5, test analysis: according to the requirements of users to automatically obtain, ReH, ReL, Fm, Rp0.2, Rt0.5, Rm, E and other test results.

4.2.6, test report interface: the software operating system provides a powerful report processing function, customers can print out their own needs according to their own needs test report. Test data can be stored, printed, and then analyzed.

5 safety protection device

L when the test force exceeds the maximum test force of 3%, overload protection, pump motor stop.

L when the piston rises to reach the limit position, the stroke protection, pump motor stop.

Analysis of loading and calibration device of WEW-L computer screen display steel wire testing machine

1 loading device

By the two synchronous belt reduction unit, a planetary gear reducer, screw nut.

Test machine work and relaxation test machine servo motor according to the control unit from the signal rotation, through the secondary slow drive rotates the nut, forcing screw to move up and down, to achieve load or space adjustment action. Because the lead screw is self locked, so the motor stops thick, can keep its displacement as a constant, so as to measure the force and time, the relationship between stress and time. The limit switch installed in the base limits the maximum stroke of the screw and plays the role of safety protection.

2 calibration device

In order to facilitate the calibration of the force value, the relaxation test machine is generally configured with a reverse rack, which is composed of a supporting plate and a pull rod. In the work, the bearing plate and the pull rod are first put into integration, and the pull rod is connected with the drawing and the concrete, and the final position of the bearing plate is in a horizontal state when the connection is connected.

WEW-600L/1000L microcomputer screen display steel wire test machine operating procedures

1. We must first determine whether the surrounding environment, such as around medium corrosion, no electromagnetic interference, no impact vibration source interference; test ambient temperature 20 plus or minus 2 DEG C, 10 hours of temperature fluctuation shall not be greater than + / - 0.5 DEG C, relative humidity is less than 80%; fluctuation of grid voltage does not exceed the rated voltage of + 10% and a good grounding;

2 in the case of environmental safety, the connection of each power supply line, open the WEW-600L/1000L computer screen display steel wire test machine, the host power supply and control measurement system. If the experiment space is larger, the position of the beam can be adjusted through the rise and fall, and the preparation of the test sample is made.

3 installation of samples, the user can install the sample according to their own habits to install, can be installed on the sample, can also be installed under the sample.

4. Sample after installation, in WEW-600L/1000L computer screen display steel wire testing machine software input various parameters, choosing the initial stress, according to the size of the steel strand, the selection limit should force of 70% or 80% as the initial stress.

5. The beginning of the experiment, experiment system can be in accordance with the standard requirements within 3-5 minutes will strand loading nominal maximum force of 70% or 80%, keep 1 minutes automatically start recording test data, reached the set time automatically after the termination of the trial.

6 after the end of the test, print test data, unloading steel wire and other specimens, usually test requirements to do a lot of group test. The user can follow the steps above. If all of the experiments are finished, clean the site and lubricate some parts for the next experiment.
