IIEquipment application scenarios:

It is mainly used for testing and analyzing the mechanical properties of metal and non-metal materials such as tension, compression, and bending. It has three closed-loop control methods of stress, strain, and displacement, and can calculate parameters such as maximum force, tensile strength, bending strength, compression strength, elastic modulus, fracture elongation, yield strength, constant deformation elongation, constant force elongation, and the corresponding relationship between specified force and deformation. according toGB, ISO, JIS, ASTM, DIN and other international standards are used for testing and providing testing data.

This system can completeSynchronous stretching and asynchronous stretchingThat isWhen different stretching speeds are set for XY, the material's deformation under stress and the attenuation of force values change. Upgrade softwareAnd toolingcan be completed1 * 1 to 2 * 2 equal area expansion and stretching. (Software and tooling need to be customized, and the clamping part of the tooling will automatically elongate.)

fourMain functions:

The host adopts a metal frame structure, which is stable and reliable. A high-precision loading control mechanism is composed of servo motors, reducers, roller screws, etc., which drives the chuck to move forward and backward to achieve the loading of the cross.The X/Y direction roller screw is strictly installed orthogonally at a 90 degree angle, and the four-way chuck X/Y axis is installed coaxially to ensure that it is in a unified tensile force plane.

1) Four way linkage synchronous loading (in-situ stretching, the sample remains in place, the system automatically adjusts based on relative force and single point relative displacement, and loads synchronously with constant displacement to ensure balanced force distribution of the sample in the stretching area,

2) Four way servo motor independent control loading,Measurement feedback of independent loading force in the orthogonal direction of XY axis to ensure synchronization of the loading process/AsynchronousAnd the stability of tension and load-bearing capacity.

3) It has limit protection function and overload/overcurrent protection function for any working position, reliable and safe.

4) After the experiment is completed, it has an automatic reset function to restore to the initial state, which facilitates the installation and fixation of the next sample.

5) Plate heating system, evenly distributed heating tubes, filled the entire testing space with heating capacity through circulating fans and multi-point air outlets. The air outlet is arranged in a spiral pattern and does not directly blow the test piece,

6) In addition to the testing space arranged with stainless steel inner liner and insulation layer, measures should be taken to prevent heat loss and personnel burns,

7) The upper cover is a tempered glass observation window, which is used to observe the experimental process and the condition of the sample, （beltHigh definition camera, Used for remote observation)

8) Equipped with a computer control system and a powerful test database, the test data can be saved, queried, and called at any time, with data recording and calibration report reporting functions.

9) Specialized measurement and control software can achieve various control modes such as manual control, automatic control, constant rate force control, constant rate deformation control, and constant rate tension control.

10) Users can customize the stretching mode from 1 * 1 to A * A or A * B according to their needs. The two power axes stretch themselves according to the internally defined speed relationship. During the stretching process, displacement and load can be maintained to observe the attenuation of force values, as well as force and load, displacement and elongation, and the influence of temperature on the stretching process,

11）The clamping fixture is pneumatic clampingMulti head synchronization, all pipelines are made of high-temperature resistant products to ensure no gas leakage or pressure loss during long-term operation,

8) Special clamping fixture, convenient for sample replacement,
