Description

1. Product introduction
The computer tensile testing machine is mainly used for stretching, compressing, bending, shearing, Mechanical properties test of tearing, peeling, cycling, etc. It is widely used in material inspection and analysis in industries such as factories and mines, quality supervision, aerospace, machinery manufacturing, wires and cables, rubber and plastics, textiles, construction and building materials, and home appliances.
The design of the host computer and auxiliary equipment of the computer tensile testing machine has the characteristics of beautiful appearance, convenient operation, stable and reliable performance. The computer control system controls the rotation of the servo motor through the DC speed control system, and then decelerates through the deceleration system. The high-precision screw pair drives the moving beam to rise and fall to complete the tensile test of the sample. The series of products are pollution-free , Low noise, high efficiency, has a very wide speed range and beam moving distance. Equipped with a wide range of auxiliary tools, it has very broad application prospects in metal and non-metal mechanical performance tests. The machine is suitable for various test fields such as quality supervision, teaching and scientific research, aerospace, steel metallurgy, automobiles, rubber and plastics, woven materials and so on.

5. Performance characteristics
1. Excellent appearance design. Our company has been paying great attention to the appearance of products for many years, and has developed many products that are comparable to foreign models. The surfaces are all electrostatic spray patterns;
2. Key components. Adopt international famous brands, such as: Panasonic servo system, Taiwan Taibang servo system, etc., and German nano-control photoelectric encoder, etc.
3. The arc tooth type synchronous belt deceleration system has the advantages of high efficiency, long life, low noise and maintenance-free. At present, many domestic counterparts continue to use worm gear reducers. The main reason is that their servo system still adopts analog speed control method. Due to the inherent zero drift and imbalance of analog control, absolute zero speed cannot be achieved, so the self-locking effect of worm gear and worm must be used to stop. And what we use is the pure digital phase-locked loop position pulse control mode without zero drift and no offset.
4. Loaded with high-precision ball screw, stable loading, long life of the testing machine, good long-term stability and energy saving.
5. A variety of protection measures. Such as: various electrical protections in the power link, software overload, over-displacement protection, mechanical mandatory safety limit protection, etc.
6. Simple, reliable and powerful user interface.
