It is widely used in the production process control of metallurgy, casting, machinery, metal processing, automobile manufacturing, non-ferrous metals, aerospace, chemical industry, etc., and the inspection of finished products in the central laboratory. It can be used for Fe, AL, Cu, Ni, Co, Mg, Analysis of Ti, Zn, Pb and other metals and alloy samples. It can accurately and quantitatively analyze the non-metal elements (C, P, S, B, etc.) and metal elements in flake, block and rod solid samples, with accurate analysis results and high analysis precision.

The test force divided by the surface area of the indentation is the Vickers hardness value. Vickers hardness value calculation formula: HV = constant × test force / indentation surface area ≈ 0.1891 F/d2. In the formula: HV-Vickers hardness symbol; F-Test force (in N); d-the arithmetic average of the two diagonals d1 and d2 of the indentation (in mm). In practice, the Vickers hardness value can be obtained by looking up the table according to the diagonal length d. The national standard stipulates that the diagonal length of Vickers hardness indentation ranges from 0.020 to 1.400mm.

Test to determine a series of characteristics of a material under tensile load is also called a tensile test. It is one of the basic methods of material mechanical performance test, mainly used to check whether the material meets the specified standards and study the performance of the material.

• The temperature is 10-35 degrees, and it is not considered room temperature if it exceeds
• The cross-section of the sample or product is not less than 1mm
• The sheet is 0.1-3mm thick and the width is at least 20mm
• The diameter of the cylinder should be greater than 3mm, the length should be at least 250mm, and the diameter of the cylinder should be greater than 10mm.
• Under 80mm, only the tensile strength can be obtained, and the metal wire should be stretched more than 1 meter.

This testing machine uses a high-speed DSP platform with high integration, powerful control, data processing capabilities, and high reliability. It adopts a fully digital, force, deformation, and displacement control system with an adaptive PID algorithm to realize force, deformation, and displacement. Control, each control loop can be automatically switched, and it can control and maintain the rate of test force, deformation, displacement, etc., USB1.1 communication, plug and play interface, this interface can be hot plugged, that is, it has plug and play function . Makes the layout of each interface neat and reasonable, easy to plug and unplug. The system board uses a 4-layer PCB unique anti-interference wiring method, which has strong anti-interference ability. The entire control system has high cost performance and high reliability. The entire test process is controlled by a microcomputer, real-time dynamic Display load value, displacement value, deformation value, test speed and test curve. Using a computer for data processing and analysis, the test results can be automatically saved, the test curve can be recalled after the test, and the test process can be reproduced through curve traversal. The test software under the full Chinese Windows platform has strong data and graphics processing functions , It can print out a complete test report and test curve in real time, with complete limit protection, overload protection, emergency stop and other safety protection functions. The data results that can be obtained: tensile strength, yield point, yield strength, elongation after fracture, Area shrinkage after fracture.

It is used for the bending and forming of various metal sheet materials such as iron, stainless steel, copper, aluminum, and as a press to complete easy mold forming, pressure riveting, leveling, and break forming. The workpiece is cut on LASER and NCT, and other non-bending forming primitives are produced in the tongs, and then bent into shape by using the folding bed knife mold or the folding bed easy mold on the folding bed. In addition, the convex The processing of primitives such as wrapping, pressing pad angles and pressing lines is usually performed on the folding bed. Using the folding machine knife mold and the folding machine easy mold, the folding machine can complete the bending of many types of products, but its processing speed is slower than that of the punching machine. It is suitable for bending forming during sample production and partial non-bending forming and mass production. Some bends into shape.

The highest temperature that the main test material can withstand.

An environmental test that mainly uses artificially simulated salt spray environmental conditions created by salt spray test equipment to assess the corrosion resistance of products or metal materials. It is divided into two categories, one is natural environmental exposure test, and the other is artificial accelerated simulated salt spray environmental test. The artificial simulated salt spray environment test is to use a kind of test equipment with a certain volume space-the salt spray test box, and use artificial methods in the volume space to create a salt spray environment to assess the quality of the salt spray corrosion resistance of the product . Compared with the natural environment, the salt concentration of chloride in the salt spray environment can be several or tens of times the salt spray content of the general natural environment, which greatly increases the corrosion speed. The salt spray test is performed on the product and the result is obtained The time is also greatly shortened. For example, if a product sample is tested in a natural exposure environment, it may take 1 year for its corrosion, while the test under artificially simulated salt spray environment conditions requires only 24 hours to obtain similar results.
