Die forging
What is die forging?
Die forging is a kind of forging, mainly through the forging machine forging, forging through the forging machine to forge the blank, and then forming in the mold, so as to achieve the required effect.
Die forging process flow
The die forging process mainly has the following steps: blanking – heating – pre-forging – final forging – cutting – heat treatment – cleaning – inspection.
Cutting is based on the customer’s drawings to cut the material, such as the customer’s forging part size is relatively large, will choose large size bar material (15cm), appropriate late inch cutting, will save size, but also speed up the forging part time.
The second step is heating, which needs to be heated to the cut bar. We know that metal will also undergo thermal expansion and contraction, and the reason for heating the metal bar is to make the metal soft, so that when pre-forging, it is convenient to forge, and it is also convenient to form.
Forging pre-forging is the first step of forging through the forging machine, so that the initial forging, and then through the final forging, directly to achieve the predetermined size effect. The choice of forging machine according to the size and thickness of the size to choose, if the forging part is relatively large, relatively thin, you can use more than 2000 tons of forging machine, our factory has 2000 tons of forging machine, can forge various parts for customers.
After forging, the edge will be cut off, the excess part will be cut off, and then the oxide can be treated by sandblasting, which can achieve the forging of the finished product clean. Heat treatment is carried out according to customer requirements, and sometimes customers require high hardness, heat treatment is needed to improve the hardness of forged parts. Of course, forging parts can also be machined.
Application range of die forging parts
The application range of die forging is very wide, such as the automobile industry, construction machinery, shipbuilding, railway equipment, oil pipeline, military equipment industry and so on.
Automotive industry such as engine parts, chassis parts, truck parts, military industry such as tank parts, engineering construction industry such as excavator parts, heavy construction machinery: excavator, bulldozer track plate, sprocket and so on.
Characteristics of die forging parts
Compared with casting parts, the first is suitable for mass production, suitable for mass production, high production efficiency, the second is high accuracy, the dimensional accuracy of the die forging parts is high, the shape is close to the finished product, the subsequent processing is reduced, and the surface has no porosity. Third, it can manufacture parts with complex shapes, especially for parts with complex surfaces or cavities, and forging parts with special characteristics. Fourth, a wide range of applications, widely used in aerospace, automotive, machinery and other fields.

The video is the details of the forging, the forging process of the workers.
There are two kinds of die forging, one is open die forging, and the other is closed die forging
