The press brake tooling is a tool used by the press brake to bend and shape metal sheets, mainly through the method of changing the physical state of the metal sheet through pressure to achieve the processing of the shape of the object. A tool used to turn a blank into a workpiece with a specific shape and size under the pressure of a press brake. Generally, 42CrMo material is used, which has high strength, high toughness, and good wear resistance. Cold working die steel is selected, and Cr12MoV is a good material. The usage performance can be met, and the process performance is also good, but the price will be higher. 42CrMo is a high-strength alloy quenched and tempered steel with high strength and good toughness, which can work below 500 degrees.
