Design method of forging three-dimensional technique

Abstract

The invention relates to a design method of forging three-dimensional technique, and solves the problem existed in the forging technique design applying a two-dimensional model at present. The method includes steps of developing a unique forging three-dimensional technique design system on the basis of a manufacturing process management system (MPMS), and then integrating the system with a CAN modeling system, a technical process simulation analysis system, a product data management system, and a typical knowledge base; the main function of the system after integration includes 1) design of manufacturing parameter; 2) storage of three-dimensional technical model; 3) technical database; 4) forging of mould base; 5) typical technical knowledge base; 6) simulative data management base; 7) electronic auditing and signature, and visible holographic publish. The design method improves the technical design efficiency, guarantees the technical quality, shortens the technical development cycle, and greatly improves the yield and the manufacturing rate of the forging piece; meanwhile, the method further provides a condition for the technical knowledge accumulation of the enterprise.

Description

technical field [0001] The invention relates to a three-dimensional process design method, in particular to a forging three-dimensional process design method. Background technique [0002] At present, the forging process design adopts a two-dimensional model, and the process design is completely dependent on the only two-dimensional diagram that expresses the design intention. Restricted by its expressive power, a lot of energy of the craftsman was wasted in the conversion from the physical image to the abstract two-dimensional view expression, and ambiguity and deviation inevitably appeared. The formed craft lacked verification, and the craft design process The problems that cannot be exposed in the process are moved to the manufacturing process. This process design method has the following specific defects: [0003] 1) During the process design process, the 3D model issued by the design department cannot be directly used to carry out process design.

Problems solved by technology

Restricted by its expressive power, a lot of energy of the craftsman was wasted in the mutual conversion from the physical image to the abstract two-dimensional view expression, and ambiguity and deviation inevitably appeared. The formed craft lacked verification, and the craft design process The problems that cannot be exposed in the process are moved to the manufacturing process. This process design method has the following specific defects:

[0003] 1) During the process design process, the 3D model issued by the design department cannot be directly used to carry out process design

[0004] 2) poor consistency

During process design, it is necessary to convert the 3D model into a 2D graph, resulting in non-unique data sources, which cannot be associated with the product design model

And when the same product is compiled by different craftsmen, different plans will be obtained, lacking consistency, and it is difficult to fully and correctly consider the forging process in the initial stage of product design, and the feedback and modification of problems in the forging process are slow and difficult to achieve

[0005] 3) Process design and process simulation are disconnected, simulation parameters and process design parameters cannot be automatically transferred, and the workload of repetitive labor is large

[0006] 4) The visual expression of the process cannot be realized, and the operability and ease of realization of tooling and molds cannot be evaluated, which brings inconvenience to production

[0007] 5) The rationality of the process can only be verified by the actual forging process, but there is no means of evaluating whether the process has reached the optimum
