Bending machine mold
Bending machine mold, English is press brake tool. It is a tool used by the bending machine to form and process sheet metal. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. A tool used to make billets into parts of a particular shape and size under the pressure of a bending machine.
The material of the bending machine mold is generally T8 or T10, T10A, and the better 42CrMo material, which mainly requires high strength, high toughness and good wear resistance.
The selection of cold work die steel Cr12MoV is a very good material, the use of performance can be met, the process performance is good, the price will be high.
42CrMo is a high strength alloy tempered steel, high strength, strength and toughness, can work below 500 degrees.
The bending machine die is divided into bending machine die and lower die, which are used for sheet metal stamping forming and separating die. The mold for forming has a cavity, and the mold for separating has a cutting edge.
Stroke adjustment, in the formal start of bending work with the bending machine mold need to test. There must be a gap of plate thickness when the bending machine dies run down to the very bottom. Otherwise, it will cause damage to the mold and machine. The adjustment of the stroke is also electric quick adjustment and manual fine tuning.
In addition, it is prohibited to use the bending machine mold to fold ultra-thick iron plates or quenched steel plates, high-grade alloy steel, square steel and plates that exceed the performance of the bending machine, so as not to damage the machine tool.
