Microcomputer controlled high temperature electronic universal testing machine

Adopting innovative design concept and manufacturing technology, integrating precision high temperature box and tensile testing machine is an improved model specially designed to simulate the physical performance test of various materials under different environmental conditions. For example, this machine is equipped with a high temperature test box, which can test the physical properties of materials such as tensile force, pressure, shear force, etc. in different temperature environments. When using the normal temperature test, the high temperature box can be removed to increase the use space and convenience. This equipment is suitable for the test and analysis of the mechanical properties of metal materials, metal materials and composites. It can be used for tensile, compression, bending, shearing, tearing, peeling, bursting, fatigue and other tests when equipped with corresponding fittings. The maximum test value, breaking value, elongation, tensile strength, yield strength, compressive strength, modulus of elasticity, shear strength, tear strength, peel strength and other parameters can be calculated dynamically. At the same time, it can also realize the testing of the requirements of constant elongation stress, constant strain elongation and load holding. It has three closed-loop control modes of stress, strain and displacement. The machine is widely used in the material inspection and analysis of building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastic, automobile manufacturing, powder metallurgy and other industries. It is a scientific research institute, colleges and universities, mining enterprises, technical supervision Ideal test equipment for commodity inspection and arbitration departments.

Main components：

CMT5305GW microcomputer controlled high temperature electronic universal testing machine is an electromechanical integration product, mainly composed of mainframe (including frame, base, transmission system), fixture, deformation measurement system, software system and electrical system.

Introduction to main features：

The main machine adopts a gantry single-space structure, and the test space is in the lower space, which is mainly composed of the base and the frame.

Host frame：

The upper crossbeam and worktable are fixed with high-strength light bars to form a high rigidity frame structure; The high-precision ball screw without clearance is adopted to improve the transmission efficiency and displacement accuracy; The coaxiality of the testing machine is good (<8%). The upper, middle and lower beams are made of QT600-3 ductile iron with tensile strength of 60k (600MPa) and yield strength of 40k (400Mpa). The corrosion resistance and oxidation resistance of ductile iron are better than that of cast steel. Due to the microstructure of nodular graphite of ductile iron, it is better than cast steel in reducing vibration energy, so it is more conducive to reducing stress.

Control transmission system：

The internationally leading full-digital imported AC servo motor with high control accuracy and high response frequency is adopted to ensure high efficiency, low noise and balanced transmission of the transmission system, and the allowable speed error is not more than ± 0.2%. The maximum test speed range is 0.001~1000mm/min. The circular arc tooth synchronous belt transmission has the advantages of high transmission accuracy, transmission efficiency of 98%, more accurate, stable and low noise.

Force measuring sensor：

Adopt imported strain gauge load sensor with high stability and precision; The high-precision measurement system with high stability ensures that the resolution of the whole process remains unchanged, and the maximum error of the test force indication is not more than ± 0.5%. Multiple load sensors can be used according to different ways to realize the multi-range test force range measurement; Good temperature compensation, high sensitivity, high rigidity and good long-term stability.

Fixture

Standard special clamps for various materials are easy to operate and reliable to hold. They can be configured with pneumatic and hydraulic wedge clamps and horizontal push hydraulic clamps to greatly improve the working efficiency. The clamping force can be adjusted to meet the user's test requirements for different materials. They can also be customized according to customer needs；

Deformation measurement system：

A variety of electronic extensometers can be equipped according to different materials and specifications, and digital large deformation measuring system (measuring system with wide deformation measuring range, high accuracy and fast response) can also be equipped to realize high accuracy measurement of large deformation materials such as rubber and plastic.
