Function summary:

       The reaming testing machine is mainly used to measure the reaming rate of sheet metal. It is composed of the punch loading system controlled by electronic servo, the blank holding force pressing system and the visual camera system. It can pre-judge the crack occurrence time according to the force attenuation, manually intervene to stop, and automatically calculate the reaming rate by measuring the aperture through the digital caliper。The equipment adopts microcomputer to control the whole test process, and the supporting TestPilot software can display the blank holding force, punch punch pressure, punch displacement, test speed, etc., which is specially used for the test of the reaming and forming performance of metal sheet。 

Main features:

1, the use of electronic servo control, high-precision visual camera system, PLC as the main control system, with strong control capabilities, data processing capabilities and high reliability。Manual intervention to stop the test when cracks appear in the sample;It can also determine the time of crack occurrence more accurately through the video playback function。

2. TestPilot software provides a simple and intuitive operating interface for material or industry testing, which can not only meet the requirements of simple, easy-to-use and efficient quality control, but also meet the requirements of personalized testing required by scientific research institutes for in-depth study of material properties。The whole control system has high cost performance and high reliability。

3, real-time dynamic display of blank holder force value, impact pressure value, test speed and test curve。

4, all Chinese under the Windows platform test software, with strong data and graphics processing functions, can print out a complete test report and test curve。Adjustable holding force, high control accuracy。

Relevant standards:

• GB/T 15825.4 "Sheet metal formability and test methods - Part 4: Reaming test"

• ISO/TS 16630 Metallic materials-Method of hole expanding test
