摘要: In a magnetic workpiece holder and gauge for a press brake, the core of an electromagnet for the work core is electrically insulated, and connected to a circuit for energizing the electromagnet when electrical contact is made between a magnetic workpiece and the core structure of the electromagnet. A probe may also be provided for detecting the lateral alignment of the workpiece.
