  Testable item

  

  (I) Common test items :(ordinary display value and calculated value)

  

  ● Tensile stress ● Tensile strength

  

  ● Tearing strength ● Tearing elongation

  

  ● Constant stress ● Constant stress elongation

  

  ● Fixed stress and force ● Tearing strength

  

  ● Force value at any point ● Elongation at any point

  

  ● Extraction force ● Adhesive force and take the peak value to calculate

  

  ● Pressure test ● Shear force peeling force test

  

  ● Bending test ● Pull out force puncture force test

  

  (2) Special test items:

  

  1. The elastic coefficient is the elastic Young's modulus

  

  Definition: the ratio of the normal stress component to the normal strain in the same phase. Is the coefficient of rigidity of a material, the higher the value, the stronger the material.

  

  2. Proportional limit: the load can maintain a proportional relationship with the elongation within a certain range, and the maximum stress is the ratio ji limit.

  

  3. Elasticity limit: the maximum stress that a material can bear without permanent deformation.

  

  4 elastic deformation: remove the load, the deformation of the material completely disappeared.

  

  5. Permanent deformation: after removing the load, the material is still deformed.

  

  6. Yield point: when the material is stretched, the deformation increases and the stress remains unchanged. This point is the yield point. Yield points are divided into upper and lower yield points, generally above yield points as yield points.

  

  Yield: When the load exceeds the proportional limit, it is no longer proportional to the elongation. The load will drop suddenly, and then over a period of time, the load will rise and fall, and the elongation will change greatly. This phenomenon is called yield.

  

  7. Yield strength: the quotient of the load when the permanent elongation reaches a specified value, divided by the original sectional area of the parallel part.

  

  8. Spring K value: the ratio of the force component in the same phase with the deformation to the deformation.

  

  9. Effective elasticity and hysteresis loss:

  

  In the electronic energy test machine, with a certain speed will be a sample stretching to a certain elongation or stretching to the specified load, determination of the sample contraction recovery work and stretch when the work consumption percentage, that is, the effective elasticity; The hysteresis loss is the hundreds of the ratio of the energy lost during the elongation and contraction of the test specimen to the work consumed during the elongation.

  

  Three, the use of the operation box

  

  On the operating box

  

  "Up" is the fast up on the main form;

  

  "Down" is the fast down on the main form;

  

  "Stop" is the stop on the main form;

  

  "Run" is the run on the main form;

  

  "Clearing" is the clearing on the main form;

  

  "Micro up", "Micro down", "Slow up" and "Slow down" are used for very slow down control of the test bench when the force value is calibrated and calibrated. It is point moving (also known as inch moving) mode: moving when pressing, and stopping when loosening.

  

  7. Matters needing attention

  

  7.1 Before starting the machine, it is necessary to check whether the connecting wires, plugs, sockets, power plugs and sockets of the control system and the host are correct or loose, and then start the machine (for example, if the grounding wire of the power socket in the controller of the numerical control system is loose, the host will be out of control). Please remember the starting sequence, first turn on the main machine power, then turn on the control system power. When shutting down, first turn off the power supply of the host machine, then turn off the power supply of the CNC system, and shall not unplug any plug after starting up.

  

  7.2 It is very important to check the position of the upper and lower limit retaining rings. There should be a certain distance between the two clamps to avoid damage of parts due to misoperation or the host being out of control, especially the sensor.
