SCARA robot makes a big impact: An agile and fast robot solution was needed to remove specimens from a liquid nitrogen bath and then position them accurately for a drop test

摘要

When a robot system was [required for use on an impact testing machine produced by Imatek, the company contacted TM Robotics for a solution. The application uses Toshiba Machine SCARA robots to test large diameter line pipes that will ultimately be used for carrying fluids at high pressure. Preparation for the Drop Weight Tear Test (DWTT) process involves cutting a segment from the^pipe, flattening it and putting EuadtcTTon one side as a crack initiator. The segment of pipe is then immersed in liquid nitrogen, to cool it down to -160°. Placing the pipe in this cooling bath causes embrittlement before the specimen is then positioned on an anvil in a drop-weight testing machine and broken into two pieces.
