[0002] The open fixed table press has high precision, reliable performance and easy operation; it can be equipped with an automatic feeding device to realize semi-automatic stamping operation. The open fixed table press is suitable for various cold stamping processes such as shearing, blanking, punching, bending, shallow drawing, etc. of sheet metal, and is widely used in various industrial manufacturing departments. The open fixed table press uses a crank-connecting rod mechanism, which is a mechanism that changes rotary motion into reciprocating linear motion. The crank-connecting rod mechanism drives the slider to reciprocate linear motion to give the upper die a punching force to stamp the sheet metal. However, in the specific implementation process, the staff needs to place the workpiece on the workbench for stamping. When the workpiece is held or not effectively positioned, the workpiece will be offset during the stamping process, reducing production efficiency and posing a hidden danger to the personal safety of the workers.
