Design of Die Structure for Hot Forging
Hot forging is the process of forming metals and alloys under the action of high temperature, by means of pressure and plastic deformation. With the improvement of the efficiency of hot forging press, the research on the improvement of die structure and the optimization of process parameters has been increased, making hot forging a cost-effective, efficient and reliable process.
The design of hot forging die structure is important for the production efficiency and product quality. In the design of die structure for hot forging process, the first step is to accurately determine the forming size and shape of the workpiece. As the workpiece size and shape change, the die structure should be adjusted accordingly. The second step is to determine the forging process. The forging process requires the forging temperature, forging speed, feeding speed, and die clearance of the die. When designing die structure, the effects of the parameters on die structure and forming should be considered. The third step is to determine the type of the die. According to the requirements of forming process and the size of the forming force, apart from the shape of the forming part, the form and type of die should be determined.
Since the die structure determines the quality of the hot-forging product, it is necessary to accurately design the die structure to optimize the forming process. The most important requirements for die structure design are that the die should have sufficient strength and toughness, and should not easily deform. The surface of the die should be smooth, and the die should not be corroded by heated metal. The review of the die should be comprehensive and all aspects of the requirement should be considered.
In the design of die structure for hot forging, finite element analysis is often used to simulate the forming process in order to verify the feasibility of the design and optimize the design. The finite element model is used to calculate the distributions of stress, strain and temperature in the process of forming. The results can be used to determine the strength of the die, the forming force and the possibility of fracture of the metal under the action of high temperature.
To ensure the quality of the forging product, the die structure must be designed reasonably. The die structure should have sufficient strength and toughness, and the collision parts should be processed reasonably. In addition, the surface of the die should be smooth and corrosion resistant, and the clearance of the parts should be ensured. Finally, the whole die should be tested carefully to ensure that it meets the requirements of the forming process.
In conclusion, to optimize the design of die structure for hot forging, finite element analysis should be used to simulate the whole process, and parameter adjustment should be made to meet the requirements of forming process. The design of die structure for hot forging should also be evaluated carefully in order to ensure the quality of the product.
