Five, host structure

This testing machine adopts horizontal structure,ByHost Framework,PLC control system, oil source system, span adjustment mechanism, test angle acquisition mechanism, bending loading mechanism,Bending center and sample clamping mechanismSuch as composition.By loading two two-way cylinders, the automatic reverse bending test can be realized, the manual change of sample direction can be avoided, and the work efficiency can be improved. The high-precision angle encoder is used to measure the bending angle, and the control accuracy is high. At the same time, the touch screen is easy to operate, the data display is intuitive, the equipment runs smoothly, the noise is low, and the use is reliable and the life is long.

Six,Equipment features

  1. The main frame is made of thick steel plate, with high strength, no deformation and long service life.
  2. Use of PLC control systemSiemensPLC controller and7 inchColorColor TouchScreen, high acquisition rate, fast response speed, accurate data display,Can automatically adjust the span, one-button loading,Automatic realization of positive bending90 degrees, reverse bend 20 degrees.
  3. The oil source system adoptsServo valve control, high control precision, smooth loading.
  4. The span adjustment mechanism adopts servo motor control,Screw drive, optical axis guide, high positioning accuracy.
  5. Angle acquisition mechanism selectionHigh precisionAngle encoder,Directly installed under the rotating roller, read the rotation angle of the roller, the data is more accurate and reliable.
  6. The bending loading mechanism adopts two loading cylinders, respectively, for the positive bending loading cylinder and the reverse bending loading cylinder, which avoids the replacement of the pressure head and the turning of the sample during the test of the same cylinder.
  7. The bending center is quenched, with high hardness, wear resistance and long service life. The specimen clamping mechanism can meet the requirements of simultaneously carrying out multiple specimen tests,φ28The followingCan3complete the test at the same time,φ32-φ40, Can2Complete the test at the same time.
