The Manufacturing Process of Metal Punch Press Dies
The manufacturing process of metal punch press dies refers to the transformation of metal raw materials into finished products through designated processing techniques and process management to process and assemble dies. The process of manufacturing metal punch press dies is quite complex, and now the die industry is gradually developing into automated production, which facilitates high quality and efficiency. The die manufacturing process includes four steps: production technology preparation of materials, manufacturing of blanks, processing of parts and components, and die testing and identification.
1.Production Tchnology Preparation Materials
Preparation of various product manufacturing materials for the design of die parts. Prepare the metal materials and select the materials with the required performance according to the product requirements.
2.Manufacturing of Raw Materials
The manufacturing of blanks plays a major role in the manufacturing industry, as raw materials have not undergone any shape processing before processing.
3.Component Processing
Heat treatment of raw materials is commonly carried out through methods such as heating and quenching to enhance their hardness and toughness. Processing the surface of the blank, such as painting, sandblasting, coating, etc., can help improve quality and corrosiveness.
4.Trial Die Identification
To conduct quality inspection on the manufactured blank to meet high-quality standards and design requirements of the parts.
Metal Punch Press Dies Assembly and Characteristics
There are many types of punch press dies, mainly composite dies, continuous dies, as well as cold punch press dies such as bending dies and deep drawing dies. Each assembly corresponds to different technical requirements, which can be roughly divided into the fixing method of die parts, adjustment of fit gaps, and other technical requirements, with the same technical requirements.
However, in terms of assembly sequence, guidance accuracy requirements, and adjustments during the assembly process, specific technical requirements are also required according to different processing parts and die structure requirements. The structural definitions of composite dies, bending dies, and continuous dies include the following:
1.Composite Die
A composite die is composed of multiple components or modules, which helps to achieve multifunctional and high-precision processing requirements. It is a die that completes multiple stamping processes in the same part of the die in one working stroke of the press.
The composite die has the characteristic of high punching accuracy, and the manufacturing accuracy of the die is required to be high. As several processes are completed on the same workstation, they have the same positioning reference. By using a combination of multiple components, efficient manufacturing can be achieved while reducing costs, which can meet the different needs of each component.
Composite die structures are widely used in the field of metal processing. During assembly, insert the convex and concave dies between them, and then implement their corresponding positions. After implementing the assembly of punching convex dies and cutting concave dies, the convex and concave dies are modified and assembled based on the assembly reference of the convex and concave dies. Assembly is carried out in the above order, which helps to quickly change the areas that need to be adjusted.
2.Continuous Mode
Continuous die is a die structure used for continuous production and processing. It usually consists of multiple workstations, each of which completes a part of the die sequence for processing or operation. In a continuous die, the workpiece flows between various workstations, goes through a series of processing steps, and finally completes the entire processing process.
This die structure is suitable for situations that require high production efficiency and large output and can achieve fast and efficient production of large quantities of products.
Continuous dies are commonly used in industries such as automotive parts, electronic products, and plastic products, which can improve production efficiency, reduce production costs, and ensure the stability of product quality.
3.Bending Die
A bending die is used to bend dies for metal materials. It consists of two parts, including an upper die and a lower die, whose main function is to bend the material with the help of applied pressure or force, causing permanent deformation and obtaining the specified shape and size.
Bending die metal processing plays a crucial role and is widely used in industries such as automotive manufacturing, aerospace, and building structures.
If there is unevenness in the bottom surface between bends during the bending die trial punching, it is due to uneven distribution of the missing material rods, and the top bending occurs during the missing material. The solution is to evenly distribute the missing rods or increase the number of missing rods and increase the pressing force.
The Development of Metal Punch Press Dies Manufacturing Technology
Metal stamping die manufacturing technology has played an important role in the field of die manufacturing, mainly producing large quantities of metal workpieces. Metal punch press dies have been rapidly applied in the die industry of industrialized countries, especially in the manufacturing technology of large-scale, precision, and long-term dies, which has a significant impact on national die manufacturing technology. In the gradually developing manufacturing industry, metal punch press dies are also being applied more and more widely. The widespread use of metal punch press dies has the advantages of high production efficiency, low cost, and high product quality.
With the continuous generation of new materials, metal punch press dies are also constantly using new materials. The use of new materials such as powder and steel. The use of these new materials will effectively improve the service life, corrosion resistance, and wear resistance of metal punch press dies.
In terms of precision machining and manufacturing technology, high efficiency has improved the quality and precision of metal punch press dies. Some technologies will be used, including laser processing, which can meet the high-precision production requirements of the product and greatly reduce manufacturing time and labor costs.
With the development of network big data, metal punch press dies are becoming increasingly intelligent. Manufacturing technology can automate the production of dies, using three-dimensional modeling processing methods, and these dies have the characteristics of complex structures.
1.Using New Die Materials
With the development of die manufacturing technology, there are increasingly strict requirements for the quality and functionality of dies. Nowadays, we are constantly developing die materials and various unique die materials, with the aim of each material corresponding to different performance dies. To maximize the performance of die materials, they are widely used in different industries.
2.Cold-working Die Steel
Cold work die steel is a material that has a wide range of applications, and multiple categories, and is used in large quantities. It mainly has the characteristics of high strength wear resistance and strength.
The commonly used cold work die steel can be divided into two development trends: one is to reduce the amount of carbon and alloy elements, which helps to evenly distribute carbides and improve the toughness of the die.
Another approach is to improve the wear resistance of the die, which is suitable for efficient, large-scale, and automated production of high-speed steel. The use of powder materials for production has high wear resistance and can also improve toughness. The dies made from powder high-speed steel generally have the characteristic of long service life, and generally have a longer service life than ordinary steel dies.
3.Steel-bonded Hard Alloy
Steel-bonded hard alloys are widely used in multi-station precision punching dies, with the advantages of high hardness and high wear resistance. At present, the hardness of steel-bonded hard alloys is diversified in various industries. From the original TiC WC develops TiN There are various types of TiCN, TiB, etc. The bonding phase continues to expand, and iron-based alloys mainly include various components such as carbon steel, alloy steel, tool steel, hot work die steel, and high-speed steel.
Metal punch press dies meet various performance requirements and new mold materials are constantly emerging. With the help of new materials, the manufacturing accuracy and productivity of dies are rapidly improved, the service life of metal punch press dies is increased, and the development of metal stamping die manufacturing technology is efficiently promoted.
