Different molds are composed of different parts. It mainly realizes the processing of the shape of the article by changing the physical state of the molding material. A tool for making a blank into a product with a specific shape and size under the pressure of a bending machine.
Cold working die steel Cr 12MoV is a good material with satisfactory service performance, good process performance and high price.
42CrMo is an alloy quenched and tempered steel with high strength and good toughness, which can work below 500 degrees.
Extended data:
Bending machine die is divided into bending machine upper die and lower die, which are used for stamping and separating sheet metal respectively. The mold for forming has a cavity, and the mold for separating has a cutting edge.
When the bending work of the die using the bending machine officially begins, the stroke adjustment needs trial operation. When the upper die of the bending machine goes down to the bottom, the gap of plate thickness must be ensured. Otherwise, the mold and machine will be damaged. The adjustment of the stroke is also electric quick adjustment and manual fine adjustment.
In addition, it is forbidden to fold super-thick iron plate or quenched steel plate, high-grade alloy steel, square steel and sheet metal exceeding the performance of sheet metal bending machine with bending machine die, so as not to damage the machine tool.
