Choosing the right hammering force and speed is a very important step in the forging process, which has a direct impact on the quality and performance of forgings. Here are some common options:
1. Deformation characteristics of materials: Different materials have different deformation characteristics. It is necessary to determine the appropriate hammering force and speed according to the hardness, toughness, plasticity and other factors of the material. Generally speaking, the harder the material and the lower the toughness, the greater the hammering force and speed are required to achieve deformation; conversely, the softer the material and the higher the toughness, the smaller the hammering force and speed are required.
2. The shape and size of the forging: the shape and size of the forging will also affect the choice of hammering force and speed. Larger forgings require higher hammering forces and speeds to ensure uniform deformation and shape accuracy, while smaller forgings require lower hammering forces and speeds to avoid excessive deformation or shape imprecise.
3. Forging temperature: Forging temperature will also affect the choice of hammering force and speed. Generally speaking, the higher the forging temperature, the smaller the hammering force and speed should be used to avoid excessive deformation and cracking; on the contrary, the lower the forging temperature, the greater the hammering force and speed should be used to achieve sufficient Deformation and shape accuracy.
4. Production process requirements: production process requirements will also affect the choice of hammering force and speed. For example, for a forging that needs to be forged multiple times, it is generally necessary to use a smaller hammering force and speed to avoid excessive deformation and inaccurate shape; speed to achieve sufficient deformation and shape accuracy.
It should be noted that when selecting the hammer strength and speed, it is necessary to comprehensively consider the above factors and select the appropriate parameters. At the same time, tests and adjustments are required to ensure that the quality and performance of the forgings meet the requirements.
Will the choice of hammering force and speed affect the surface quality of forgings?
The choice of hammering strength and speed will have a certain impact on the surface quality of forgings. During the forging process, the hammering force and speed will directly affect the deformation and surface quality of the forging.
If the hammering force and speed are too high, it will cause defects such as tearing, cracks, and air bubbles on the surface of the forging, which will reduce the surface quality and integrity of the forging. At the same time, excessive strength and speed will also lead to excessively deformed areas inside the forging, affecting the mechanical properties and service life of the forging.
On the contrary, if the hammering force and speed are too small, the surface quality of the forging may be better, but the forging efficiency is low, and multiple forgings are required to achieve the desired shape and size. In addition, too small strength and speed will also lead to insufficient internal deformation of the forging, which will affect the mechanical properties and service life of the forging.
Therefore, when selecting the hammering force and speed, it is necessary to comprehensively consider the shape, material, forging temperature and other factors of the forging, so as to meet the forging quality requirements and ensure the forging efficiency. At the same time, it is also necessary to pay attention to controlling the stability and consistency of the hammering force and speed during the forging process to ensure the surface quality and integrity of the forging.
