How to use tensile testing machine from two aspects

1. SmallTension testerElectrical working principle

Basic principles of the electrical principle block diagram of the xK-1 automatic small tensile testing machine. When working, first debug the display to a zero value, and preset the tensile test piece at elongation a to start the start signal. The voltage signal output by the sensor is first entered into the filter to filter out all spikes and AC interference, and then enter the amplifier for amplification. The output digital signal is displayed as a force value. Because of the start-up, the motor rotates the coded disk and the coded disk has 50 through holes to form a binary loop code. Photoelectric coding is a high-precision axis angle conversion into an encoded electrical signal, that is, it is converted into a corresponding digital quantity (length quantity) by the optical conversion method. The control system controls the action of the relay according to the preset pulse value (pulse conversion length) to make the motor rotate or stop working.

Technical performance:

Load: O～3ON; Frequency: 50Hz; Accuracy: 2×10-2N; Resolution: 1/200 (2×10 N per word); Power supply voltage: 220V±10; Test piece length: 40toni (variable); Display value: 1999; Test specimen tensile length grade: 3O, 5O, 7O, 1O0; Display mode is a light-emitting diode display; the primary element adopts a tension sensor, which can work continuously.

2. Mechanical principle part of small tensile testing machine

This machine uses a reversible motor to drive the screw, and the pole drives the sliding sleeve and the cross bridge, so that the lower clamp can move up and down. When the motor rotates the lower clamp in a forward direction, the lower clamp moves downward, the sample is stretched, and the appropriate one is obtained through the above tension sensor.
