Brief introduction to motor manufacturing process
Without advanced process technology, it is difficult to produce advanced products. The motor manufacturing process involves the processing and processing of motor parts and the assembly of parts into products. It is necessary to formulate and adopt appropriate process plans and processes according to product characteristics, production types and specific conditions of the manufacturing plant in order to achieve efficient production. , lean manufacturing. Today, Ms. discusses the traditional process flow of motor manufacturing to clarify the important conditions necessary to ensure the quality and reliability of the motor.
General and differentiated requirements for process measures
●Single and small batch production General parts processing uses general machine tool equipment and general tooling, which is processed by factory technical management personnel and workers. The focus of the process is to develop process plans for key components that affect product quality and to address related quality issues.
● Medium-volume production generally uses general machine tool equipment and special process equipment to produce or use a program that is easy to adjust to control machine tools and digital control machine tools. A more complete process specification is required.
● Mass production uses special machine tool equipment to organize automatic or semi-automatic production lines for production; it requires systematic and in-depth analysis and research on product structure and process parts, and develops complete process regulations.
Facts have proved that the greater the production volume, the more special machine tools and special process equipment are used, the more detailed the process work, the higher the production efficiency, the lower the cost of the product and the more stable the quality. Due to the wide variety of motor products, in a factory, there are often single production, small batch production and mass production of large batches of products at the same time, which increases the difficulty of production technology management, affects production efficiency and product quality is not easy to improve rapidly. .
Craft work is a bridge between design and manufacturing
● Analyze the process design of the product design, formulate the process plan and process method, plan the special process equipment required; verify the new process method and key process equipment, deal with the process problems occurring in the production, and carry out the process test research work, etc. The content is quite extensive.
• The intention of the process staff is generally communicated to the relevant executive department through the process documentation. The complexity and form of the motor process documentation vary with the type of production. Generally, it can be divided into two categories: one is to guide technical operation and technical inspection, such as process sheet, process code and inspection procedures, etc., generally called process specification. The other type is used for organizational production, such as process cards, product process flow charts, and so on.
● Process documentation must be thoroughly considered and in-depth analysis, technical requirements for product design drawings; annual production and batch size of parts; supply of raw materials or blanks; and technical equipment and workers' technology of the contractor Proficiency, etc.
The characteristics of the process documentation
● Technical. It should be able to fully meet the technical requirements of the product drawings and ensure the quality is stable and reliable as much as possible. Therefore, when selecting the processing plan and processing method, it should pay attention to adopting the correct process arrangement and appropriate process equipment to achieve the required technical requirements; generally it is not appropriate to rely too much on the worker's operation skills.
● Economical. Under certain production and cooperation conditions, the most economical means should be considered to achieve the required technical requirements; and attention should be paid to giving full play to the favorable conditions of the department and try to eliminate or improve the weak links in production.
●Technical safety and working conditions. Special attention should be paid to technical safety and working conditions when preparing process documents. Process methods that impair the health of workers or increase labor intensity are not allowed to meet technical requirements or improve economic results.
● Promote the development of new technologies and improve the technical level of the factory. In addition to being familiar with existing processes, process personnel should also pay attention to the research and promotion of new technologies. The development trend of relevant technologies should have a good comprehensive analysis capability and foresight, and be sensitive to adopting appropriate new technological achievements to develop production and improve the technical level of the factory.
