Forging Technology : Feature of Mould Design and Stamping Process for Flat Forging
To make a quality metal forging, the starting point is the design. For any metal forging, the exact molding process must be planned. Besides, the choice of forging processes also depends on the structural and material requirements. One of the most important forging processes is called forging technology, which uses hammering and forming to create metal parts with smooth surfaces and excellent strength for use in various industries. In this article, we will discuss the die stamping process and the features of die design in flat forging technology.
Die stamping is a type of forging process where a metal dies is clamped and hammered. During the process, a cavities is formed in the metal part, allowing for certain shapes and sizes. To perform this process, die stamping machinery and tools are needed. These include a hammer, a die, and a die holder. A die is a rigid plastic or metal plate formed in a certain shape and size. It has a hole in the middle, which is filled with a pressing material such as sand. The material is then compressed with a hammer, forming the holes and grooves in the part.
To ensure that the die will perform according to the part needs, the mold needs to be designed correctly. Design considerations should include: the type of material being used, physical and chemical properties of the material, the number of parts to be formed, the strength of the part, the tool life, and the size and shape of the part. All these design factors govern the design of the molds, including size and shape of the cavities, ejection pin diameters, and number of molds needed.
Die stamping is normally chosen for flat forging parts. There are several advantages to using flat forging. First, the process eliminates the need for costly machining and finishing operations. This is because the parts are already formed and ready for assembly, thus reducing cost and time. Second, since all the parts are formed in a single cavity, there is no need for cutting or trimming each part. This also eliminates additional cost and time for assembly. Third, when using high volume runs, the cost for a complex part can be considerably lower than what would be required if machining was used.
Die stamped parts are also strong and resilient due to the increased internal strength. This is because the pressure needed to form the parts is high, which results in a forging with high internal strength. Finally, flat forging is better suited for mass production as the tooling required for large volume production is much simpler and cheaper.
In conclusion, forging technology is an essential part of forming metal components for many industries. Die stamping is a common forging process used for flat forging parts and it is characterized by the features of its die design. The die is formed to the exact size and to meet specific physical, chemical and structural requirements. By carefully planning and choosing the right die design and material, successful flat forging components can be produced.
