General experimental method of film stretching machine

How much do you know about the general test method of the tension machine, the general situation of the tension machine is how to operate it?

1. Before the test of the tensile machine, the adjustment of the upper and lower stroke set ring, to the required range of the lower limit position, so that the following fixture can be touched by the limit switch and test stop.

2. The tensile testing machine when choose the appropriate test speed and stepless speed control will rotate speed knob on the control panel to have been detected speed indicating digital can be.

3. Starting the power switch, the power supply through the machine with different control panel.

4.Tensile machine the correct device specimen, specimen, the fixture selection appropriate, in accordance with the test materials of the type selection of fixture specimen first folder in a tensile machine fixture, start the motor to make the moving plate jig to ascend to the appropriate position holding specimen, disk clamping can not be tension or compression, to prevent the impact of test results.

5.Pulling machine starting test software can force the value of the force, the displacement automatically cleared, and then is ready to take over the test.

6.Start pulling machine the rising key to moving plate rise and fall at the beginning of the test, this time began to show tensile specimen numerical, until a fracture, the load to maintain maximum value, after the recording of the data to fracture specimens, in the clamping sample software numerical gauge zero after the test, if the test has been completed, please turn off the power.
