During forging, it is also necessary to clean the surface of the die promptly to avoid scratching or cracking of the metal surface.

How can the mechanical properties of metal be improved during forging?

During forging, the mechanical properties of metal can be significantly improved through reasonable heat treatment and forging processes. In terms of heat treatment, processes such as quenching and tempering can be used to adjust the crystal grain structure and phase composition of the metal, thereby improving its hardness and strength. In terms of forging processes, processes such as repeated folding, bending, and twisting can be used to refine the crystal grain structure of the metal, improving its toughness and fatigue resistance.

How can the dimensional accuracy of workpieces be controlled during forging?

The dimensional accuracy of workpieces is one of the important indicators for measure the level of forging process. To control the dimensional accuracy of workpieces, high-precision dies and fixtures need to be used, and the design and processing accuracy of the dies need to meet requirements. During forging, processes such as stamping, bending, and straightening can be used to control the dimensional accuracy of workpieces. At the same time, regular maintenance and upkeep of the dies should be carried out to avoid wear and tear.

How can the appropriate lubricant be selected during forging?

The lubricant plays an important role in the forging process as it reduces friction between the die and workpiece, reducing wear and surface roughness. When selecting an appropriate lubricant, factors such as the material of the workpiece, process requirements, and lubricant properties need to be considered. Common lubricants include graphite, molybdenum disulfide, engine oil, hydraulic oil, etc. When selecting a lubricant, experiments and comparisons should be carried out based on actual conditions to determine the best type and amount of lubricant.

How can the temperature of workpieces be controlled during forging?

The temperature of workpieces is an important parameter during forging as it directly affects the forging effect and workpiece quality. To control the temperature of workpieces, appropriate cooling methods such as water cooling or air cooling can be used along with reasonable heating and保温措施. It is also important to control parameters such as the charging temperature of workpieces, heating temperature, and forging temperature to ensure temperature stability during forging.

How can the appropriate die material be selected during forging?

The selection of die material is crucial for the forging effect and die lifespan. When selecting die materials, factors such as the material of the workpiece, process requirements, die shape and size need to be considered. Common die materials include cast iron, cast steel, alloy steel, stainless steel, etc. When selecting die materials, comprehensive analysis based on actual conditions should be carried out to determine the best type and heat treatment process of die materials.

How can the service life of dies be improved during forging?

Improving the service life of dies is one of the important measures for reducing production costs and improving production efficiency. To improve die lifespan, high-strength and high-wear-resistant die materials such as hardmetals or ceramics can be used. It is also important to control die processing accuracy and heat treatment processes to avoid premature wear or cracking of dies. During forging, die maintenance and upkeep should also be carried out promptly to clean surface oxides and impurities to avoid damage to dies.

How to achieve automated production in the forging process?
