Metal Stamping Die
Metal stamping dies have been widely used in fields such as automotive and aerospace. The use of metal materials to produce various parts has various advantages, such as high production efficiency and large-scale production.
Metal Stamping Tooling
Metal stamping tooling is a pressure processing method that uses pressure installed on stamping equipment to separate or deform materials, resulting in the required parts. Metal stamping die can also be called stamping or stamping parts. Stamping is generally a cold deformation process applied to materials at room temperature, and the core is processed into the applied parts using sheet metal, so it is also called cold stamping or sheet metal stamping.
These are one of the main methods of material pressure processing or metal processing, included in material forming engineering.
The tooling used for stamping is called a stamping tooling, abbreviated as a punching tooling. Magnesium stamping die is a specific tool used to manufacture batches of metal materials into the required stamping parts. Metal stamping die plays a crucial role in stamping, and only stamping toolings that meet the requirements can be produced in bulk; Only with advanced stamping toolings can advanced stamping processes be achieved. Stamping technology, toolings, stamping equipment, and stamping materials constitute the three elements of stamping processing, and they must be combined to produce stamped parts.
It is an advanced manufacturing technology that cannot be compared and replaced by other processing methods and has strong competitiveness in the manufacturing industry. Metal stamping tooling forming is a very important processing method in modern industry, used to produce various sheet metal parts with various specific advantages. Its formed parts need to have advantages such as lightweight, high stiffness, high strength, good interchangeability, low cost, convenient production process, mechanical automation, and high production efficiency. It is widely used in the production of automobiles, energy, machinery, information, aerospace, national defense industry, and daily life.

Types of Metal Stamping Tooling
There are various types of toolings, roughly divided into single process toolings, composite toolings, and progressive toolings. To determine the form of the tooling, it is necessary to rely on the requirements of the stamped workpiece, the number of batches required for production, and the conditions for tooling processing. There are many types of stamping toolings, and based on the nature of the work, the structure of the tooling, and the materials used in the tooling, stamping toolings can be classified.
Classified by process attributes, it is mainly divided into four categories: punching toolings, bending toolings, stretching toolings, forming toolings, and riveting toolings:
1.Blanking Tooling: A tooling in which materials are separated along a closed or open shape.
2.Bending Mold: To implement a workpiece tooling with a certain angle and shape, the plate or other blank should be bent along a straight line.
3.Drawing Tooling: The blank becomes an open hollow part, further changing the shape and size of the tooling.
4.Forming Tooling: It is a tooling that directly replicates the shape of the blank or semi-finished product based on the convex and concave toolings, while the material itself only produces local plastic deformation, such as bulging toolings, shrinkage toolings, expansion toolings, undulating forming toolings, flanging toolings, forming toolings, etc.
5.Riveting Tooling: Use external force to connect or overlap the participating parts in a certain order and manner, and then form a whole.
The degree of process combination can be roughly classified into four categories: single process toolings, composite toolings, progressive toolings, and transfer toolings:
1.Single Process Tooling: During the stroke of the stamped part, stamping is carried out once each time.
2.Composite Tooling: With only one station, two or more stamping processes are completed simultaneously on each punching machine and workstation.
3.Progressive Dies (Continuous Dies): There are two or more workstations in the feed direction of the blank, and two or more stamping processes are carried out step by step at different positions on a one-stroke press.
4.Transfer Tooling: It conforms to the characteristics of single process toolings and progressive toolings, mainly using a mechanical arm transmission system to implement rapid transfer within the product tooling, greatly increasing production efficiency, reducing production costs, saving material costs, and maintaining stable quality.
According to the corresponding processing methods of products, toolings can be mainly divided into five categories: punching and shearing toolings, bending toolings, drawing toolings, forming toolings, and compression toolings:
1.Punching and Shearing Tooling: Using shearing to process the tooling.
2.Bending Tooling: According to the shape, accuracy, and production situation of the part, bend the flat hair embryo to an angle.
3.Drawing Dies: Produce containers with a bottom but no gaps on the rough surface.
4.Forming Tooling: refers to the method of locally deforming and changing the shape of the rough embryo in the form of convex forming tooling, curling edge forming tooling, necking forming tooling, hole flange forming tooling, and circular edge forming tooling.
5.Compression Tooling: Adopting strong pressure to cause the metal blank to flow and deform into the desired specific shape.

The Working Principle of Metal Stamping Tooling
Metal stamping tooling is a tool used for stamping metal materials. Its working principle is to apply some pressure on the metal material using the tooling, produce plastic deformation, and obtain the desired shape and size from it. Stamping toolings are generally composed of upper toolings, lower toolings, and tooling seats, which utilize the relative motion of the upper and lower toolings to process metal materials.
The design and manufacturing of the upper and lower toolings have played an important role. The structure and dimensions of the upper and lower toolings must be accurately matched to achieve stable machining accuracy and surface quality during the machining process. Moreover, the material selection of the tooling also plays a crucial role, generally using high-quality alloy steel or hard alloy materials to ensure that the tooling has high hardness and wear resistance.
The working principle of metal stamping tooling is based on the plastic deformation characteristics of metal materials. During the stamping process, plastic deformation occurs due to the pressure exerted by the tooling on the metal material, resulting in specific shapes and sizes. This plastic deformation is achieved through the local compression and shear of metal materials by toolings, so the design and manufacturing of toolings must consider the deformation laws and characteristics of metal materials.
The working principle of metal stamping tooling is based on the plastic deformation of metal materials by the tooling, and the processing of metal materials is completed through cooperation between the tooling and the stamping machine. Stamping toolings are widely used in modern manufacturing, including automotive, household appliances, electronic products, and other fields, playing a crucial role in product quality and production efficiency.

With an unprecedented consensus on the importance of developing advanced manufacturing technology, stamping forming technology has made unprecedented progress in both depth and breadth, characterized by the combination of high-tech and many changes in strategy and system. The penetration and cross-integration of computer technology, information technology, modern measurement and control technology, and other stamping fields have promoted the formation and development of advanced stamping forming technology.
The metal stamping tooling process can be divided into four basic processes:
1.Punching: The stamping process that separates the sheet metal, including punching, cutting, trimming, and sectioning.
2.Bending: The stamping process of bending a sheet metal into a specific angle and shape along the bending curve.
3.Deep Drawing: Using flat sheet metal to make various open hollow parts, or further changing the shape and size of the hollow parts.
4.Local Forming: A stamping process that uses various local deformations with different properties to change the shape of a blank or stamped part, such as flanging, bulging, leveling, and shaping processes.
