Sheet metal formability testing machine

ECSeries sheet metal forming test platformIntroduction

At present, the sheet metal forming testing machines on the domestic market are mainly limited by their structure, which adopts a multi column hydraulic compression and a lead screw to provide tensile force. This structure is complex, bulky, and provides a small range of tensile force, and can only test the national standardGB15825As stipulated inside2mmTesting of sheets within thickness

ECThe series plate forming experimental platform has the advantages of high testing accuracy, multiple expandable testing functions, large tensile thrust, and separately controllable edge pressure and tensile force. It can perform various tests beyond10mmForming test of high-strength sheet metal with thickness. The testing platform of this project plays a crucial role in the existing automotive lightweighting technology, sheet metal forming process research, material physical property testing, welding process evaluation, and lubricant grading. After our platform experiments, we can obtain * design parameters, reduce material waste in the industrial field, and achieve energy-saving and environmental protection effects,Product meetsISOTheGBTheDINTheASTMWaiting for experimental standards
