1、Introduction
The semi-automatic Vickers hardness tester integrates the latest professional technologies such as optical imaging, mechanical displacement, electronic control, digital imaging, image analysis, and computer processing. The control of the Vickers hardness tester and the automatic stage is realized through the host computer, and Digitally image the hardness indentation on the computer screen, and then accurately measure the microhardness of metal and some non-metallic materials, various coatings and coatings, the depth of the hardened layer, the thickness of the coating, and the thickness of the coating by means of automatic reading and manual reading. Point spacing, etc. It can also photograph the topography of the metal surface and perform fixed-magnification printing. This system breaks through the traditional hardness test method and realizes fully automatic, high-precision, and highly repeatable hardness test. It is an important equipment for material analysis.
2.Composition
The computer host controls the action of the hardness tester and receives the corresponding information of the hardness tester through the RS232 serial port; the computer host controls the platform control box through the RS232 serial port, and controls the movement of the automatic stage and receives the corresponding information through the platform control box; Vickers hardness The optical signal of the indentation pressed by the meter is imaged on the computer monitor through a digital camera, and then the Vickers hardness value is measured through automatic and manual reading.
Main functions
| materials | introduce | |
| Pressure control | When the test force of the hardness tester is converted, the system senses the change of the test force and displays it in the system in real time. | |
| turret control | The software controls the hardness tester to switch between the objective lens and the indenter without manual control of the hardness tester. | |
| Load control | The software controls the hardness tester to load, without manual control of the hardness tester. | |
| Measurement control | The software controls the hardness tester turret, loads and directly reads the Vickers hardness value | |
| Light source brightness control | Set the brightness of the light source | |
| Image Acquisition | Real-time display of hardness images, images can be stored, printed, and printed at fixed times. | |
| Manual/automatic measurement | Manual: pull diagonal measurement, two-point card line measurement, four-point measurement, automatic: automatically find the four vertices of the indentation, fast speed, accurate data. Continuously hit and measure, hit and measure immediately, and suppress by designated coordinates. | |
| Hardness conversion | According to Chinese standards, automatic conversion of Brinell-Rockwell-Vickers-Knoop hardness values, real-time display, and conversion to various international standards | |
| Graphic report | Automatically record the measurement data, automatically generate the hardness-depth curve, save or print the hardness-depth curve and all indentation measurement values; save or print the indentation image and the current indentation hardness value;
The inspection report can be customized according to user requirements; through the data processing software, the hardened layer depth value formed after continuous measurement of the sample can be displayed in the form of a table; various measurement data, D1, D2, hardness value table, hardened layer depth, Maximum value, average value, minimum value, display and output each indentation picture. Data such as hardness value, hardness table, hardened layer depth map and picture insertion can be flexibly edited and printed in WORD or EXCEL to print out a test report containing mathematical statistics and hardened layer depth curve and saved in WORD format or EXCEL, and the observed samples can also be printed The topography map is saved and directly reflects the microstructure of the indentation and background, |

| Knoop measurement | Replaceable Knoop indenter for automatic Knoop hardness measurement | |
| Automatically carrying goods table | The point can be automatically selected by clicking any point in the interface with the mouse, and the start position of the straight line can be set and the random moving position can be set. The automatic XY stage stage can be controlled by the mouse to move arbitrarily in 8 directions, and the speed can be adjusted. It can be reset automatically, and the coordinates can be cleared at will;
The software system can be programmed to control the movement of the automatic stage, and the system provides 14 modes: 1) Along the line; 2) With an angle along the line; 3) Free click; 4) Along the horizontal line; 5) Along the vertical line; 6) Multiple lines along the curve; 7) Matrix along the curve; 8) Arc; 9) Tooth center; 10) Tooth tops are parallel; 11) Automatically along the edge with angle; 12) Automatically along the edge matrix; 13) Center of circle; 14) Parallel to multiple tooth tops along the curve. |
