Intelligent auxiliary designing system for sheet metal components

Abstract

The invention discloses an intelligent auxiliary designing system for sheet metal components. The intelligent auxiliary designing system comprises a model database, a model information reading and writing module, a sheet metal technology generating module and a technologic outcome output module, wherein the model database comprises a technologic database for storing technologic process parameters and a formwork database for storing part parameters, the model information writing and reading module is used for extracting basic model information from the model database and writing formwork files generated by the technology generating module in the model database, the technology generating module generates a technologic formwork file capable of facing normal equipment and numerically controlled equipment according to a pre-edited formwork, and the technologic outcome output module is used for outputting technologic card files to the numerically controlled equipment or an appointed storer and storing a complete technological procedure for the sheet metal into the model database. By the aid of the intelligent auxiliary designing system for the sheet metal components, sheet metal processing precision can be improved, and intelligentization, standardization and practicability of the technological design for the sheet metal are realized.

Description

technical field [0001] The invention belongs to the technical field of computer aided design, in particular to an intelligent aided design system for sheet metal parts. Background technique [0002] With the rapid development of the information industry, the design and processing of sheet metal parts are undergoing profound changes. At present, advanced equipment such as CNC punching machines, CNC shearing machines and CNC bending machines have been widely used in domestic sheet metal processing equipment. However, the sheet metal process design that connects the design and manufacture of sheet metal parts still depends on the manual completion of process designers to a large extent. For example, the main work of the technicians in the sheet metal workshop is to calculate the outer dimensions of the unfolded parts of the sheet metal parts, and determine the blanking size according to the expanded dimensions. [0003] Due to the limitation of personal experience, the divers...

Problems solved by technology

[0003] Due to the limitation of personal experience, the diversity and low efficiency of manual labor, it is difficult to achieve the optimization and standardization of sheet metal process, and it leads to heavy design workload, repeated labor, long processing cycle, high cost and consistency of process design Difficult to guarantee and other issues, can not meet the needs of the development of modern advanced manufacturing technology

In addition, people have not yet fully grasped the mechanism of plastic deformation of sheet metal parts. When designing sheet metal processes, process designers often can only proceed based on their own experience or some recognized empirical formulas, which cannot meet the increasingly sophisticated external dimensions of products. requirements

The flow of employees usually brings a huge loss of experience to the company, and the past historical experience of the company cannot be accumulated and precipitated
