Selection and application of cold forging and hot forging production equipment

Cold forging and hot forging|high quality product manufacturer in China

Cold forging and hot forging are two common forging processes in the field of metal working. They play an important role in manufacturing, especially in the automotive, machinery, aerospace and other industries. In order to achieve high quality forging products, it is very important to choose the right cold forging and hot forging production equipment. This paper will introduce the equipment commonly used in cold forging and hot forging production, such as press, heating furnace, etc., and the key points of equipment selection.
First, cold forging production equipment
1. Press: In cold forging production, press is critical equipment. According to the working principle and structural characteristics, the press can be divided into mechanical presses, hydraulic presses and numerical control presses. Among them, the mechanical press is suitable for mass production and has the advantages of simple structure and low cost. Hydraulic press is suitable for complex shape, high precision requirements of the workpiece, with high pressure, adjustable stroke and other characteristics; Numerical control press has the characteristics of high degree of automation and good precision.
2. Mold: Cold forging die is a key factor in determining product quality. The mold design should consider the material, structure, heat treatment and other factors to ensure that the mold has good wear resistance, fatigue resistance and adhesion resistance.
3. Auxiliary equipment: cold forging production also needs some auxiliary equipment, such as cutting machine, straightening machine, feeder, etc., to improve production efficiency and product quality.
Second, hot forging production equipment
1. Heating furnace: In hot forging production, heating furnace is the key equipment. According to the heating method, the heating furnace can be divided into gas furnace, resistance furnace, induction furnace, etc. Gas furnace has the advantages of fast heating speed and low energy consumption. Resistance furnace is suitable for small batch production and has the characteristics of high temperature control precision; Induction furnace has the advantages of fast heating, energy saving and environmental protection.
2. Press: In hot forging production, the press is also crucial. Compared to cold forging presses, hot forging presses require higher stiffness and stability to withstand the enormous pressure at high temperatures.
3. Mold: The design of hot forging dies is similar to that of cold forging dies, but the impact of high temperature on die materials needs to be considered. Therefore, the hot forging die material should have high red hardness, adhesion resistance and oxidation resistance.
4. Auxiliary equipment: Some auxiliary equipment is also needed in hot forging production, such as cutting machine, straightening machine, feeder, etc., to improve production efficiency and product quality.
Three, equipment selection points
1. Workpiece requirements: Select the appropriate equipment according to the material, shape, size and accuracy requirements of the workpiece. For example, for high-precision workpieces, CNC presses should be selected; For large workpieces, a hydraulic press with sufficient pressure should be selected.
2. Production scale: Select the appropriate equipment according to the production scale. For mass production, mechanical presses can be considered; For small batch production, hydraulic presses or CNC presses can be considered.
3. Equipment performance: Consider the performance indicators of the equipment, such as pressure, stroke, speed, accuracy, etc. Select equipment with high performance indicators to improve production efficiency and product quality.
4. Degree of automation: According to the production needs, choose the appropriate degree of automation equipment. Equipment with a high degree of automation can improve production efficiency and reduce labor costs.
5. After-sales service: Consider the after-sales service of equipment suppliers, such as technical support, maintenance and so on. Choose a supplier with good after-sales service to ensure the normal operation of the equipment.
In short, when selecting cold forging and hot forging production equipment, factors such as workpiece requirements, production scale, equipment performance, degree of automation and after-sales service should be fully considered. The right equipment will help improve production efficiency, reduce costs, and ensure product quality. In the development of China's metal processing industry, cold forging and hot forging technology will continue to play an important role in providing high-quality basic parts for all walks of life.
