CMDW single-arm microcomputer controlled electronic universal testing machine

This product is a CMDW single-arm microcomputer-controlled electronic universal testing machine produced by Shanghai Xinshijin Instrument Equipment Co., Ltd. The following is a detailed introduction of the CMDW single-arm microcomputer-controlled electronic universal testing machine

1. Main purpose

CMDW single-arm microcomputer-controlled electronic universal testing machine can test and analyze the mechanical properties of various metals, non-metals and composite materials. It is widely used in aerospace, petrochemical, machinery manufacturing, plastic rubber, ceramic building materials, metal materials, Construction engineering and other industries, as well as institutions of higher learning, scientific research institutions, technical supervision, quality inspection stations and other departments.

Different accessories can be selected according to GB/ISO/ASTM/JIS/DIN standards and can be tested for tensile, compression, bending, peeling, shearing, tearing, puncture, bursting and various high and low temperature tests. Material's yield strength, tensile (compression, bending) strength, elongation, non-proportional strength, elastic modulus and other parameters

2. Host structure

The CMDW single-arm microcomputer-controlled electronic universal testing machine adopts a single-arm structure. The host part is composed of a column, an upper beam, a middle beam, and a worktable. The speed control system is installed at the lower part of the worktable. It has high speed control accuracy, wide range and performance. The stable servo motor drives the ball screw pair to rotate through the synchronous toothed belt deceleration system, and the ball screw pair drives the middle beam to drive the tensile attachment (or compression and bending attachment) to move up and down to realize the loading and unloading of the sample . The structure has the advantages of high rigidity, high efficiency, and stable transmission.

3. Comprehensive test platform

Microcomputer hardware platform, accurate real-time collection and processing of data, gentle measurement and control interface, intuitive and clear hierarchy, simple operation and so on.

4. Test force measurement

Load measurement: The high-precision spoke load cell is selected and equipped with a high-performance measurement amplification system to ensure the high resolution of the test force. Multiple sensors can be configured according to user needs to achieve a wide range of test force measurement.

Displacement measurement: adopts 2000P/R high-precision photoelectric encoder and precision lead screw to rotate coaxially, realizes the positional power control system through digital circuit, adopts all-digital servo controller, and controls high-performance servo motor to drive synchronous toothed belt to drive Two pairs of precision lead screw drives with high precision and no gap have the characteristics of stable loading, good low-speed performance, no gap, high transmission efficiency, low noise and smooth transmission.

5. Deformation measurement system

The CMDW single-arm microcomputer-controlled electronic universal testing machine can be equipped with a large deformation measurement system according to the requirements of the test standard.

6. protection device

The CMDW single-arm microcomputer-controlled electronic universal testing machine can adjust the position of the limit protection switch according to different tests to effectively prevent the fixture from colliding. It has protection functions such as overload, over current and leakage.
