Scope

GB/T 41264-2022 is the English-translated version of 板料折弯机器人安全要求.

GB/T 41264-2022 sets the safety requirements for sheet bending robots, the robots that feed and handle the part at a press brake.

It gives the hazard analysis, the safety requirements that follow from it - the safeguarding of the working area, the interaction with the press brake, the control system and its safety functions, the modes of operation and the emergency stop - the information for use, and the testing and validation by which conformity is shown.

It applies to Cartesian and articulated sheet bending robots. Robot makers, press brake builders and the works that install a cell use it. Issued on 9 March 2022, it has applied since 1 October 2022.

3 Terms and Definitions GB/T 12643 and the following

terms and definitions apply to this document.

3.1 Sheetbendingrobots

With more than 5 programmable axes, assist CNC sheet metal bending machine, autonomously perform reclaiming, positioning, feeding, bending follow, return, palletizing and other industrial robots.

3.2 Teach mode

The gripper of the robot is manually guided, and the operation mode of the automatic processing program for sheet metal bending is completed according to the technological requirements of sheet metal bending.

Note: The manual deceleration method of GB 11291.1-2011 is used for teaching mode.

3.3 Reappearingmode

Reproduce the teaching program to check whether the program meets the operation mode of the sheet metal bending process requirements.

Note: The playback mode is derived from the manual high-speed mode of GB 11291.1-2011.
