Product Information

Forging is a processing method that utilizes the deformation of metal materials under pressure. It changes the internal structure and shape of the metal materials through pressing and plastic deformation, thereby obtaining parts with the desired shape and size. The following will detail the processing technology flow of forgings.

1. Material Preparation: Select suitable metal materials for forging. Common forging materials include steel, aluminum, copper, etc. For each material, the corresponding material grade and specifications should be selected according to the requirements of the forgings.

2. High-Temperature Heating: Before forging, the metal materials need to be heated to a sufficiently high temperature. High temperatures help improve the plasticity and deformability of the materials, making them easier to undergo plastic deformation.

3. Die Preparation: According to the required shape and size of the forgings, corresponding dies are made. The die usually consists of two parts, called the upper die and the lower die. The shape and size of the upper and lower dies correspond to the required forgings, and they are connected together in a fixed manner.

The design of the upper and lower dies needs to consider the following aspects:

1. Forging Shape: Design the shape and geometric features of the die according to the required shape of the forgings. The die should be able to restrict the deformation of the metal materials, allowing them to undergo plastic deformation according to the desired shape.

2. Forging Size: Determine the size of the die based on the required size of the forgings. The size of the die should match the size of the required forgings to ensure that forgings meeting the requirements can be obtained.

3. Material Selection: Choose suitable die materials to ensure that the die has sufficient strength and wear resistance. Common die materials include tool steel and alloy steel.

When making the die, mechanical processing techniques such as milling, turning, and grinding are usually used to ensure the precision and flatness of the die. After the die is completed, the upper and lower dies are connected together through a fixing device to form a complete die.

4. Forging Operation: After heating to the appropriate temperature, the metal material is placed in the lower part of the die, and pressure is applied. Equipment such as hammers or hydraulic presses can be used to apply pressure. The pressure causes the metal material to undergo a series of plastic deformations under the constraints of the die, ultimately obtaining the preliminary shape of the forgings.

5. Predefined Shape: After preliminary forging, further plastic deformation of the forgings is required to achieve the final desired shape. This can be achieved by continuing to apply pressure or by performing multiple forging processes to gradually change the shape of the forgings.

6. Finishing and Shaping: Once the shape of the forgings meets the design requirements, finishing and shaping operations are needed. This includes removing excess material, trimming edges and surfaces, and performing necessary heat treatment or cooling processes.

7. Post-Processing: If necessary, the forgings may require further processing and treatment. This can include heat treatment, surface treatment (such as coating, grinding, or polishing), and machining.

The forging processing technology flow involves material preparation, heating, die preparation, forging operation, predefined shape, finishing and shaping, and possible post-processing. Through these steps, forgings with high strength, wear resistance, and dimensional accuracy can be obtained.
