Performance advantages of precision die forging
2022-09-05
Developed on the basis of die forging, it can forge some complex shapes and high dimensional precision parts, such as bevel gears, blades, aviation parts and so on.
The shape of forgings can be complex due to the die chamber guiding the flow of metal.
The forging flow line inside the forging is distributed according to the forging profile, thus improving the mechanical properties and service life of the parts.
3 Simple operation, easy to realize mechanization, high productivity. According to different equipment, die forging is divided into hammer die forging, crank press die forging, flat forging machine die forging, friction press die forging, etc.
The equipment used for die forging on the hammer is die forging hammer, which is usually air die forging hammer. Forgings with complex shapes are initially formed in the blank die cavity and then forged in the die cavity. According to the forging die structure classification: the forging die has a burr groove to accommodate the excess metal, called open die section; On the contrary, the forging die does not accommodate the excess metal flange flying groove, called closed die forging. Directly formed from the original blank, known as single die forging. Forgings with complex shapes that need to go through a number of pre-forming steps on the same forging die are called multi-die bore die forging.
Fine die forging features
1. Greatly reduce the cost of product parts, forging processing allowance is less, service is small, surface roughness value is small. It can partially or completely replace the machining of parts, thus saving data and machining hours and improving labor productivity.
2. Improve the mechanical properties and service life of the product. The metal flow line of the forging is not cut off, and the flow line distribution is more reasonable. The strength of cast parts is about 20% higher than that of cutting, with strong stress and corrosion resistance and long service life.
3. Suitable parts with complex shape, high performance and expensive data are difficult to be made by mechanical processing methods, which are costly and expensive. Precision forging has obvious saving effect, such as gears, toothed parts, blades, aviation parts and electrical parts, etc.
4 to have a suitable batch precision forging is not in any case is economic, according to the forging product production batch, performance requirements, cost and economic benefits to consider. The larger the batch, the better the benefit.
