Deep drawing of metal spinning parts is an advanced metal processing technology with unique characteristics and wide applications. In this process, the metal sheet or pipe gradually deforms on the rotating core mold through external force, forming a spun part with a specific shape and depth. Its advantages include:
High material utilization rate: Compared with other processing methods, deep drawing of metal spinning parts can more effectively utilize raw materials and reduce the generation of waste. For example, when manufacturing conical parts, it is possible to gradually spin and shape from a circular sheet metal, with almost no material waste.
Shape flexibility: capable of manufacturing various complex shapes and contours to meet different design requirements. Parts with curves and surfaces, such as the muffler part of a car exhaust pipe, can be achieved through deep drawing of metal spinning parts.
Good mechanical properties: During the processing, the fiber structure of the metal is distributed along the shape of the part, thereby improving the strength and stiffness of the part.
Cost effectiveness: It has a certain cost advantage for both small and large-scale production, especially when manufacturing large parts.
The commonly used materials for deep drawing parts mainly include various metal sheets, which depend on factors such as the characteristics, strength, corrosion resistance, and cost of the required product. The following are some common materials for deep drawing parts:
1. Low carbon steel: Low carbon steel is the most commonly used metal material for deep drawing and stamping parts, because it has good formability, strength, and weight ratio. After work hardening, the formed structural characteristics are better, and the cost-effectiveness is relatively high.
2. Stainless steel: Stainless steel has relatively high stamping difficulty, but it has unique advantages in certain specific applications. Stainless steel has good strength and corrosion resistance, making it suitable for situations with high material performance requirements.
3. Aluminum: Aluminum stretch parts are commonly used in parts such as power storage, beverage cans, batteries, and radiators. Aluminum material is lightweight and corrosion-resistant, suitable for applications that require weight reduction or corrosion resistance.
4. Copper: Although copper stretching is difficult, it has unique advantages in temperature sensing, electronics/electrical, pipeline, heat, and decoration industries. Copper has good conductivity and thermal conductivity, making it suitable for situations with special requirements for electrical performance.
5. Titanium and its alloys: Titanium is known for its low density, high strength, and high corrosion resistance, and is commonly used in building materials, spacecraft, commercial and industrial tools, as well as customized applications.
