Longmen digital electronic tensile testing machine

Main purpose
This machine can perform mechanical property testing and analysis research on metal, non-metal, and composite materials, and is widely used in aerospace, petrochemicals, mechanical manufacturing
Industries such as plastic rubber, ceramic building materials, metal materials, and construction engineering, as well as departments such as universities, research institutions, technical supervision, and quality inspection stations.
Different attachments can be selected according to GB/ISO/ASTM/JIS/DIN standards for stretching, compression, bending, peeling, shearing, tearing, puncturing, etc
Top breaking and various high and low temperature tests can detect parameters such as yield strength, tensile (compression, bending) strength, elongation, non proportional strength, elastic modulus, etc. of materials.
Host structure
The machine adopts a dual space door structure, with the upper space stretched and the lower space compressed and bent. The main unit consists of four pillars, an upper crossbeam, a middle crossbeam, and a workbench assembly
The gantry frame is installed with a speed control system at the bottom of the workbench, which is reduced by a servo motor with high speed control accuracy, wide range, and stable performance through a synchronous toothed belt
The system drives the ball screw pair to rotate, and the ball screw pair drives the middle crossbeam, driving the stretching attachment (or compression, bending attachment) to move up and down, achieving the sample
Loading and unloading. This structure has advantages such as high stiffness, high efficiency, and stable transmission.
Comprehensive testing platform
As a hardware platform, the local microcontroller accurately and real-time collects and processes data, with a gentle and intuitive measurement and control interface, clear hierarchy, and simple operation.
Experimental force measurement：
Load measurement: High precision spoke load sensors are selected, coupled with a high-performance measurement amplification system, to ensure high resolution of the test force. Can be used according to
Multiple sensors are required to be configured to achieve measurement of a wide range of experimental forces.
Displacement measurement: Using a 2000P/R high-precision photoelectric encoder and a precision screw to rotate coaxially, a digital circuit is used to measure the displacement force control system
Adopting a fully digital servo controller, the high-performance servo motor drives the synchronous toothed belt, driving two pairs of high-precision gapless precision screw drives
It has the characteristics of smooth loading, good low-speed performance, no gap, high transmission efficiency, low noise, and smooth transmission.
Deformation measurement system
Large deformation measurement systems can be selected according to the requirements of the testing standards
Protector
According to different experiments, the position of the limit protection switch can be adjusted to effectively prevent fixture collision.
It has protection functions such as overload, overcurrent, and leakage.
