WDW-100D microcomputer controlled electronic universal testing machine



I. Product introduction

The host

The main engine is a gabled prestressed frame with high axial stiffness. It is mainly composed of the upper beam, moving beam (middle part), table and light bar frame structure, ball screw is fixed between the table and the upper beam. The leading bushings of two ball screw and four light screw are fixed on the moving beam.

Structure principle

Adopt arc synchronous belt pulley deceleration, zero clearance ball screw pair transmission, transmission has no clearance, so that the test force and deformation speed precision control is guaranteed. The motor drives the lead screw to rotate after the three-stage synchronous pulley decelerates, thus driving the moving beam to make linear motion at the selected speed to achieve various test functions.

Important functions:

It is mainly used for testing and researching the mechanical properties of all kinds of metal, non-metal and composite materials, such as tensile, compression, bending, shearing and peeling. The precise automatic control and data acquisition system realizes the full digital adjustment of the data acquisition and control process. With automatic load maintenance, stress, strain control, cycle control and self-programming control and other control methods. Conduct tests and provide test data according to international standards. Automatically complete the maximum bearing capacity, strength, elongation, deformation, elongation, section shrinkage, elastic modulus and other test parameters of the material.



This company produces the microcomputer control electron universal testing machine combined with foreign advanced control technology, elegant appearance design, high efficiency of transmission system constitute a high-performance host, control system adopts the world popular high-speed parallel bus standard design, using the BB company amplifier, company AD converter and a high-speed data acquisition system of high precision load sensor measuring system. The software adopts the world's more popular high-level language to write and upgrade easily and quickly.

Professional software testing machine can achieve yield strength, tensile strength, elongation, deformation, elongation, section shrinkage, elastic modulus and other data and indicators, the computer control system of the test process control and data processing in line with the corresponding national standards of metal materials and non-metal materials, test report diversification.

This machine is widely used in materials inspection and analysis of building materials, aerospace, machinery manufacturing, wire and cable, rubber and plastics, automobile manufacturing, shock absorption system and other industries. It is the ideal test equipment for scientific research institutions, colleges and universities, industrial and mining enterprises, technical supervision, commodity inspection and arbitration and other departments.
