Problems solved by technology
Due to the differences in knowledge composition, technical quality, experience accumulation, and scope of thinking of different process designers, the formulation of process plans and selection of process parameters are relatively random during process design, resulting in the same or similar parts being processed by different processes designed by different process personnel. The design schemes are also different, and the degree of process standardization is low. This not only increases a lot of repetitive labor, but also complicates production planning and organization management. At the same time, because the original process information is not fully utilized, it also reduces the process The efficiency of manufacturing design makes it difficult for process design to achieve efficient and reasonable goals

Embodiment Construction
[0038] The technical solution of the present application will now be further described in conjunction with the accompanying drawings and embodiments.
[0039] Step 1: Classify the shell parts
[0040] For the shell parts, the geometric structure of the shell is classified according to the main structure, process characteristics and main equipment used, and the rules are found from the composition of functions and process features, as well as the similarity of the equipment used, and the division of shell parts is summarized category. Mainly divided into box-type shells, disc-type rotary shells, tank-type rotary shells, lid-type shells, special-type shells, etc., see Table 1 for the classification of shell parts, and the specific categories are as follows:
[0041] Table 1 Classification of shell parts
[0042]
[0043] Step 2: Summarize and classify the design features and manufacturing features of the shell parts;
[0044] The structure of the shell parts is complex, th...

The invention relates to a rapid process design method for shell parts. The rapid process design method mainly comprises the following steps: classifying the designed shell parts, summarizing and classifying design features and manufacturing features, establishing a manufacturing feature system and attributes of the shell parts, designing a detailed process model, establishing a corresponding fine typical process, and forming an example knowledge base; according to the category of the shell part to be designed and the fine typical process, the part manufacturing process set is combined to form the manufacturing process of the shell part to be designed, and reuse of the typical process is achieved, so that the purpose of rapid and efficient process design is achieved, the process standardization degree is effectively improved, and the process design efficiency is improved.
Description
technical field [0001] The invention belongs to the field of mechanical processing, and relates to a rapid process design technology for shell parts in the manufacturing process. Background technique [0002] At present, in the process design of shell parts, the craftsmen basically design according to the product drawings, use their professional knowledge, combine the production organization, equipment and technical status, and the production batch. Due to the differences in knowledge composition, technical quality, experience accumulation, and scope of thinking of different process designers, the formulation of process plans and selection of process parameters are relatively random during process design, resulting in the same or similar parts being processed by different processes designed by different process personnel. The design schemes are also different, and the degree of process standardization is low. This not only increases a lot of repetitive labor, but also compli...
