Press brake die: this part is usually on the bottom of the press brake, which corresponds to the upper die, and offers support and shape for the metal sheet.
Segment dies: According to the requirement of the product specification, the die can be divided into multiple independent die segments with standard lengths, such as common lengths 450 mm, and 600mm.This increases the application range and reusability.
四、Selection of materials used in the press brake die
The use of materials in the construction and operation of press brakes is a key aspect of the manufacturing process. In order to efficiently bend metal parts into the desired shape, the appropriate material for the tool must be carefully selected. The choice of material can affect the durability, accuracy, and cost effectiveness of the press brake process.
One of the key considerations in selecting materials for press brake tools is hardness. The material used for the tool must be stiff enough to withstand the forces and pressures applied during press brake without premature deformation or wear. Common materials used in press brake tools include tool steels, hard alloys, and high-speed steels, which are known for their high hardness and wear resistance.
Another important factor to consider when selecting materials for press brake tools is toughness. The die must be able to withstand the impact and stress of the press brake process without cracking or breaking. Materials with high toughness, such as high-speed steel and hard alloys, are often preferred for press brakes because they can absorb energy and resist fracture at high loads.
In addition to hardness and toughness, the materials used for press brake tools must also have good machinability. Machinability refers to the ease with which the material can be shaped, cut, and shaped into the desired tool configuration. Materials with good machinability, such as tool steels and hard alloys, are preferred for press brakes because they can be easily machined to exact dimensions and shapes.
In addition, the material used for press brake tools must have good thermal stability. Tools are subjected to high temperatures during press brake, and materials must be able to maintain their hardness, toughness, and workability at high temperatures. Materials with good thermal stability, such as high-speed steel and cemented carbide, are ideal for press brakes because they can withstand the heat generated during press brake without losing their mechanical properties.
In addition, the materials used for press brake tools must also have good corrosion resistance. During manufacturing, molds are often exposed to moisture, chemicals, and other corrosive agents, and materials must be resistant to corrosion and degradation. Materials with good corrosion resistance, such as stainless steel and coated tool steel, are commonly used in press brake tools to ensure service life and reliability.
In addition, the materials used for press brake tools must be cost effective. While high performance materials such as cemented carbide and high speed steel have excellent hardness, toughness, and machinability, they can be expensive. Manufacturers must carefully balance performance against cost to ensure that the selected material provides the desired functionality at a reasonable price.
In summary, the choice of material for press brake tools is a key aspect of the manufacturing process. By carefully considering factors such as hardness, toughness, machinability, thermal stability, corrosion resistance, and cost effectiveness, manufacturers can select the best materials for their press brakes to achieve precise, durable, and efficient press brake of metal parts. Ultimately, the choice of material plays a key role in the success of the press brake process and the overall quality of the manufactured product.
五、 Press Brake Die Standards
The common press brake die steel contains chromium and carbon. This steel features good solidness and abrasiveness, suitable for the press brake process.
Standard guide rail size and application: the guide rail with different specifications has different applications when press brake materials with different angles and thickness.
Standardization can ensure the die’s interchangeability.
Flame quenching treatment: quenches the die material via flame quenching, which makes the die obtain better abrasiveness, especially very pivotal for high-tensity press brake tasks.
Die surface treatment: fine polishing operation can ensure a tidy, clean, and flat die surface, which is essential for reducing friction, prolonging the die lifespan, and improving the surface quality of the press brake workpiece.
Die renovation: the old dies with heavy abrasiveness should be reprocessed, such as repairing grooves, repairing abrasive surfaces, flaming quenching, and recoating, making the die return to its good working state. This can prolong the use period of the die, and decrease the use cost of the die.
六、Conclusion
In a word, choosing the right mold material is very important to improve the service life and forming quality of the mold. The high quality press brake die can greatly improve the press brake accuracy, reduce the wear of the machine, so as to bring a longer service life and the best production effect. Its main components, characteristics, types, materials and standards all contribute to its effectiveness and performance in shaping and press brake materials with precision and accuracy. As technology continues to advance, the press brake tool will continue to evolve to meet the needs of modern metal working processes, making it an indispensable tool in manufacturing and fabrication operations.
