ZL 201721259588.8 A New Type of Jaw Device for Material Testing Machine

1.The oil cylinder is placed under the four column frame structure, equipped with high-strength plexiglass protective door, which is rigid, safe and stable.

2.Use hydraulic chuck to automatically clamp the sample.

3.High precision load sensor is used to measure force, with high measurement accuracy and wide range.

4.High precision displacement sensor is adopted.

5.Servo motor control is adopted, which is silent and energy-saving, and the system heat is small.

6.Use high-precision extensometer to measure the deformation of the sample.

7.The high rigid semi closed structure is adopted and the built-in design is adopted. The jaw and jaw clamp plate are not exposed to the outside of the jaw seat during the test operation, so that the force in the jaw of the testing machine is relatively balanced and the coaxiality is higher, effectively avoiding the strain of the testing machine on the jaw, jaw and jaw seat during the long-term operation, so as to solve the problems of the opposite side and deformation of the jaw seat of the testing machine.

8.The networked measurement and control system is adopted, which has the functions of gain adjustment, zero full scale, etc. to ensure the smooth operation and accurate measurement of the machine.

9.It can realize constant rate force control, constant rate stress control, constant rate strain control, constant rate travel control, low cycle fatigue control, user self programming control and other control modes.

10.It can draw force deformation, force displacement, stress strain, force time and other test curves.

PCI bus control method is adopted.

11.The main components of the hydraulic system are imported from abroad, such as the imported Siemens motor and the imported radial piston oil pump, which make the testing machine have higher loading accuracy, lower noise, better durability and enhance the stability of the machine.

12.Computer and electro-hydraulic servo system are used to control the loading and fully automatic control. The test can be completed independently according to the pre-set stress rate and curve form, and the load, rate, time and test curve can be displayed dynamically. All tests can be completed by setting parameters once.

13.Windows system control software is used to automatically calculate multiple technical parameters such as elastic modulus E, upper yield strength ReH, lower yield strength REL, specified non proportional elongation Rr, tensile strength Rm, specified total elongation Rt, maximum force total elongation Agt, yield point elongation, etc.

14.Microcomputer is used for automatic data acquisition and processing, and the test data and test curve are displayed on the screen synchronously. The test curve can be locally enlarged and can be superimposed and compared with multiple curves. It has the functions of disk storage of test results, printing test results and test curves, report processing of batch test results, database management, etc., and has network interfaces. It has LAN networking function and remote data seamless connection function.

15.The height of the whole machine is suitable for the test space, which is more ergonomic. Operators do not need to borrow tools such as steps, which is convenient to operate, reduces labor intensity and increases safety; The tester is more convenient for transportation and indoor installation.

16.Double oil circuit design is adopted to increase working efficiency and reduce noise.

17.The testing machine is equipped with a damping system to reduce vibration and noise.

18.When the test piece is stretched, the oil cylinder moves downward, the reflection force is reduced, and the noise is reduced; When the test piece is pulled off, the impact force is small and the noise is reduced.

19.It is more convenient to clean the falling oxide skin.

20.No foundation, no installation.
