What are the types of metal structural parts?
The metal structures on engineering vehicles are an important part of these heavy equipment, and they play a key role in ensuring the functionality, safety and durability of the vehicle. The following is a detailed introduction to the metal structural parts of the engineering car:
Definition and classification
Metal structural parts refer to metal components, metal parts and precision metal structural parts manufactured by casting, forging, welding and other processes with iron, steel, aluminum and other metals as the main materials. In the engineering vehicle, these structural parts can be divided into many types according to the use and manufacturing method.
1. Classification by manufacturing method:
• Cast structural parts: obtained by casting process, with complex shape and accurate size.
• Forged structural parts: After forging processing, the mechanical properties and fatigue resistance of the material are improved.
• Welded structural parts: connected by welding, widely used in the manufacture of large and complex structures.
2. By material:
• Steel structural parts: widely used, with good strength and toughness.
• Aluminum alloy structural parts: with low density, corrosion resistance, easy to process characteristics, often used in lightweight design.
• Other metal material structural parts: such as copper alloy, magnesium alloy, etc., according to specific needs.
2. Functions and characteristics
1. Bearing function: Metal structural parts are the main bearing parts of the engineering vehicle, responsible for supporting the weight of the vehicle and transferring various loads.
2. Connection function: Through welding, bolted connection and other ways, the various parts are connected into a whole to ensure the integrity and stability of the vehicle structure.
3. Protection function: Some structural parts such as guardrail, protective cover, etc., play a role in protecting personnel and equipment.
4. Lightweight design: With the progress of technology, aluminum alloy and other lightweight metal materials are more and more used in engineering vehicles to reduce vehicle weight and improve fuel economy.
