With the rapid development of the shipbuilding industry, the demand and quality requirements of port machinery forgings are also increasing. Traditional manufacturing technology has some limitations in producing high precision and high quality forgings. Therefore, the introduction of new manufacturing technologies is imperative. This paper will introduce a new manufacturing technology, additive manufacturing technology, and apply it to the production of mechanical forgings in ship ports.
Ship port machinery forging is an important part of ship machinery equipment, its quality is directly related to the performance and safety of the ship. Traditional manufacturing technology has certain limitations in the production of high-precision and high-quality forgings, such as low production efficiency and material waste. Therefore, the introduction of new manufacturing technologies is imperative. Additive manufacturing technology is a new manufacturing technology, which has the advantages of high manufacturing precision and high material utilization rate, and provides a new solution for the production of mechanical forgings in ship ports.
Traditional manufacturing technology mainly includes forging, casting, welding and other ways. These technologies can meet the basic needs of mechanical forgings in ship ports to a certain extent, but there are certain limitations in the production of high-precision and high-quality forgings. For example, traditional forging technology requires the use of a large number of molds and cavities, resulting in high production costs and a long production cycle. In addition, traditional technologies are less able to meet the needs of complex geometrics and special materials.
Additive manufacturing technology is a new type of manufacturing technology that uses three-dimensional printing to stack metal powder or other materials layer by layer into parts with preset shapes and properties. Compared with traditional manufacturing technology, additive manufacturing technology has the advantages of high manufacturing precision and high material utilization rate, and can produce complex shaped parts quickly and accurately. Therefore, additive manufacturing technology provides a new solution for the production of mechanical forgings in ship ports and has broad application prospects.
The principle of additive manufacturing technology is to layer the three-dimensional model through computer-aided design software, generate two-dimensional plane data, and then print out the corresponding shape layer by layer through the printer. The process includes three stages: data preparation, printing and post-processing. In the data preparation stage, it is necessary to use computer-aided design software for modeling and hierarchical processing according to the actual needs. In the printing stage, the material is printed layer by layer into a preset shape; In the post-processing stage, follow-up treatments such as removal of support and surface treatment are carried out on the printed parts to obtain the final product.
Compared with traditional manufacturing technologies, the advantages of additive manufacturing technology are:
(1) High manufacturing precision, can achieve the production of complex shapes and structures;
(2) High material utilization rate, reducing material waste;
(3) Short production cycle, can quickly prepare parts;
(4) Reduce the use of molds and cavities, and reduce production costs.
Applying additive manufacturing technology to the production of mechanical forgings in ship ports has the following advantages and potential problems:
Advantages:
(1) Improve production efficiency, shorten production cycle, and quickly respond to market demand;
(2) Reduce production costs, reduce the use of molds and cavities, and save costs;
(3) Improve product quality and reliability, reducing errors and defects in the traditional manufacturing process;
(4) To meet individual needs, can quickly customize and optimize product design.
Potential problems:
(1) Problems such as support structure and interlayer cracking that may occur during the printing process;
(2) After the printing is completed, the quality and stability of the parts also need to be comprehensively tested and evaluated;
(3) For the production of some traditional forgings, the cost of additive manufacturing technology may be higher than that of traditional manufacturing technology.
This paper introduces the application of additive manufacturing technology in the production of mechanical forgings in ship ports. Compared with traditional manufacturing technology, additive manufacturing technology has the advantages of high manufacturing precision and high material utilization rate, and can produce complex shape forging quickly and accurately. Its application to the production of mechanical forgings in ship ports can improve production efficiency, reduce production costs, improve product quality and reliability. However, at the same time, it is necessary to pay attention to the potential problems of additive manufacturing technology, such as support structure problems, part stability and cost problems. Therefore, in practical applications, the appropriate manufacturing technology should be selected according to the actual situation, and the respective advantages should be given full play to obtain better economic and social benefits.
