Product Introduction:

The YKW series expansion and flattening testing machine is jointly developed by our company and Zhejiang University. It is a high-tech universal automatic pressure testing machine that integrates modern machinery, electricity, and hydraulics. The metal pipe expansion, diameter expansion, and flattening testing machine is suitable for measuring the plastic deformation ability of circular cross-section metal pipes, checking and displaying whether there are visible cracks in the pipes. The expansion attachment (conical core) of this testing machine generally has 30 degrees, 45 degrees, and 60 degrees.

According to the standard:

1. GB/T246-1997 "Metallic Tube Flattening Test Method"

2. GB_T 14976-2002 Seamless Stainless Steel Tubes for Fluid Transport

3. GB/T242-1997 "Test Method for Metal Tube Expansion"

4. GB/T245-1997 "Test method for rolled edge of metal pipes"

5. GB/T2611-1992 "General Technical Requirements for Testing Machines" and other standards.

Features:

1. The testing machine adopts a microcomputer controlled electro-hydraulic servo valve to drive the hydraulic cylinder, and automatically controls the test force and displacement in multiple modes to complete the compression test and expansion test of the sample.

2. The main body of the testing machine is precision cast as a whole, with the oil cylinder placed on top, making it easy to install samples, with good stability and beautiful appearance

3. The hydraulic servo loading system adopts hydraulic pump units, original hydraulic valves, and wideband electro-hydraulic servo valves to ensure high-precision, high-efficiency, low-noise, and fast response of the system

4. Using a microcomputer controlled display system, the setting, control, data acquisition, processing, analysis, storage, and display of test parameters during the test process (including upper and lower yield points, compressive strength, fracture strength, etc.) are completed, and the control and measurement are accurate.

5. Equipped with Windows system testing machine software, it can perform statistics and processing, and then output and print various required test curves and reports. It has functions such as test curve amplification, comparison, and traversal, which are intelligent and convenient.

6. Build a powerful experimental database, where experimental data can be saved, queried, and accessed at any time, and enable data transmission and conversion with user local area networks and the internet.

7. Based on the modular design of the WINDOWS operating platform, it has simple operation, powerful functions, and a human-machine dialogue structure.

8. Realize four levels of testing force measurement, automatic switching, with a testing force measurement range equivalent to 2%

Accurate, stable, and reliable
