1. Product introduction:

This testing machine uses hydraulic loading and microcomputer control to display the test results. It is easy to operate and accurate and reliable in test readings. It is used for tensile, compression, bending, shear tests and cold bending tests of various metal materials. After the test is over Automatic calculation of mechanical properties such as the yield strength Re and tensile strength Rm of metal materials. The addition of auxiliary equipment can detect the elongation rate A and the maximum force total elongation rate Agt after breaking. At the same time, the equipment can be completed by adding the residual deformation device of the steel bar connection. The residual deformation of the mechanical connection of steel reinforcement (For the detection of residual deformation of mechanical connection of steel reinforcement, please refer to "Residual deformation device of mechanical connection of steel reinforcement"). This machine adopts the characteristics of lower oil cylinder, low height and high precision. It is an ideal high-quality testing instrument suitable for aerospace departments, scientific research units, engineering quality inspection, colleges and universities, industrial and mining enterprises.

2. Host structure:

1. A gear-type high-pressure oil pump is installed in the dynamometer housing, which is driven by a motor, and the action is stable and the sound is normal during operation.

2. The tensile space is located above the host, and the compression and bending test space is located between the lower beam and the workbench under the host.

3. The lifting and lowering of the lower crossbeam adopts a motor driven by a reducer, a chain drive mechanism, and a screw pair to realize the adjustment of the tension and compression space.

4. The hydraulic system of this machine is directly controlled by a computer, which is easy to operate to ensure the accuracy of the data.

5. The oil cylinder adopts the gap seal to reduce the friction between the piston and the oil cylinder; the general manufacturer uses a sealing ring to seal. .

3. Control system:

The measurement and control software is used for microcomputer-controlled electro-hydraulic servo-hydraulic universal testing machines to perform various metal and non-metal tests, and complete various functions such as real-time measurement and display, real-time control and data processing, and result output in accordance with corresponding standards.

(1) Authority management: Operators of different levels have different operating authority, and the contents of the menus that can be operated are also different, which makes the operation simple, convenient and fast for ordinary operators, and effectively protects the system.

(2) Test parameters: real-time measurement and display of test force, peak value, displacement, deformation and other signals; real-time acquisition and control under NT mode platforms such as Win2000 and WinXP; and accurate timing and high-speed sampling.

(3) Curve drawing: Real-time screen display of various test curves such as load-deformation, load-displacement, etc., can be switched and observed at any time, and the enlargement and reduction of the curve is very convenient.

(4) Support a variety of control methods: three types of closed-loop control of test force (stress), deformation (strain) and displacement (elongation) can be realized, and constant velocity test force, constant velocity displacement, constant velocity strain, and constant velocity can be realized Load cycle, constant velocity deformation cycle and other tests. Smooth switching between various control modes.

(5) Automatic calculation of parameters: It can automatically analyze various performance parameters such as tensile strength, yield strength, tensile strength, elastic modulus, yield strength, and specified non-proportional extension strength. It can also manually intervene in the analysis process to improve analysis Accuracy; other data processing can also be performed according to the standards provided by the user.

(6) Data storage: The test data is stored as a text file to facilitate user inquiries. The data curve of the entire test process can be recorded and saved, and it has a demonstration function to realize the reproduction of the test curve. It is also possible to superimpose and compare curves, which is convenient for comparison and analysis.

(7) Report printing: The test report can be printed in the format required by the user. Users can choose to report and output basic information, test results, and test curve content by themselves to meet various needs.

(8) Overload protection: It has the function of overload protection and automatic shutdown, and it can automatically judge whether the sample is broken, and automatically shut down; it has protection functions such as overload, overcurrent, overvoltage, upper and lower displacement limits, and emergency stop.
