Experience sharing in mechanical design and talking about industry trends

At this stage, under the situation of continuous advancement of science and technology in China, China's industrial enterprises have developed rapidly, and the corresponding industrial machinery technology has also made great progress, and the development of science and technology has become an important guarantee for the steady improvement of the efficiency of China's industrial industry. Mechanical design and manufacturing and automation technology is the inevitable product of scientific development, and has been widely used in the production field, on the one hand, it can improve production efficiency and production capacity, and on the other hand, it can well control production costs and labor intensity. The emergence of machinery and equipment has replaced manual labor, so that people can be liberated from heavy manual labor, driven by the prosperity and development of science and technology, China's machinery industry has made great achievements, especially from the application of automation technology to the field of mechanical design, the development of machinery and equipment has entered a new stage. Although China is a big country in machinery, it is still insufficient compared with developed countries in the West, so in order to better meet the development needs of enterprises, relevant institutions should improve the importance of mechanical design and manufacturing and automation technology development, understand its development needs and development direction, and further promote the overall improvement of machinery manufacturing performance and intelligence level.

The mechanical design and manufacturing process will involve a large number of parts and components of the shape, size, material and other attributes, the whole process is complex, if there is a problem, there needs to be mature experience and theoretical knowledge to solve and support, in order to ensure the assembly of the entire mechanical parts successful, smooth production, safe and stable production; The characteristics of unmanned operation such as control technology can reduce the failure of the production system and greatly improve the production efficiency and efficiency. Therefore, mechanical design and its automation is not a separate discipline, but the product of the combination and penetration of multiple technical disciplines.

The development of mechanical equipment is to meet the actual production needs of people, and its primary design principle is to meet the functional needs of the equipment, and the process of mechanical design is to conceive, analyze and calculate the working principle, structure, movement and force mode, yield strength, part material and dimensions, lubrication method and so on of the machinery according to the use requirements and transform it into a specific description as the basis for manufacturing. Mechanical design is an important part of mechanical engineering development, the first step in machine production, and the main factor that determines machine performance.

The main process of mechanical design is to formulate design tasks according to customer or market demand, and then preliminary design, including determining the working principle and basic structural form of machinery, motion design, structural design and drawing preliminary general drawings; then multiple technical confirmations, including comprehensive consideration of working performance, manufacturing costs, size and weight, reliability, consumption and environmental pollution, etc., to obtain the final optimization design; and then engineering drawings design confirmation, including drawing all engineering drawings (such as parts drawings, component assembly drawings and general assembly drawings, etc.), Preparation of all technical documents (e.g. parts list, wear parts list, instructions for use, etc.).
