The use of 3D modeling technology to guide the innovative design of machinery requires designers to take into account the novelty and creativity of the design in the process of mechanical design, making it more in line with the requirements related to the use of energy in dynamics. The use of new technologies, reflecting the practicality of mechanical product making inventions, and developing more mechanical functions that meet market needs.
In order to improve the effectiveness of three-dimensional modeling design of mechanical products, technicians should do a good job of data control and knowledge fusion, and reflect the control of product performance to the testing activities of design quality.
In the green innovative design activities of mechanical products in industrial projects, the person in charge should arrange some workers with production experience to participate in the design activities, analyze the parts most prone to wear and tear in the operation of mechanical products, and design a feasible plan to protect the core parts of mechanical products.
The basic principles of carrying out three-dimensional modeling technology development of mechanical product design
Based on the use of three-dimensional modeling technology in the mechanical product design activities, not only for the design of a mechanical product parts, but should be based on the overall mechanical products to optimize the design of the overall use of the function.
For the design and innovation activities of mechanical products, we should think innovatively about the design drawings and adopt new technologies to carry out mechanical manufacturing activities as far as possible. At the same time, the staff should also pay attention to the theoretical study of mechanical products, under the guidance of basic theory, to improve the level of skills in mechanical design and manufacturing.
In the process of conceptual design, designers should start from the perspective of industrial design and use three-dimensional technology to make multiple adjustments to component parameters to find the best design solution.
Starting from the perspective of structural analysis, designers should find the key detail features in dynamic simulation from the new modeling technology, and make targeted improvements to the insufficient parts of traditional mechanical design. Using new technologies and materials, the installation and deployment methods of mechanical parts are improved.
Measures to improve the effectiveness of 3D modeling technology development in mechanical product design
2.1 Developing the core innovation ability of mechanical designers
In order to develop the core innovation ability of mechanical designers, it is necessary for mechanics to strengthen the conceptual innovation work in design. The basic information staff should establish a perfect database of green design resources, and data should be stored for the environmental details and emission standards of each design link.
When mechanical designers develop 3D technology for new products, they can take the classic 2D model design method in this type of product as a blueprint, absorb the excellent ideas in traditional design activities, further implement the 3D model assembly method innovation in traditional products, and reflect the exploration and innovative use of new technologies in the design of virtual prototypes.
Mechanical designers in the process of design, must carefully refer to the details of standard design standard issues to ensure that the design of mechanical products in line with the relevant national emission standards, to promote energy saving, environmental protection and efficient production of mechanical products.
In the use of three-dimensional modeling technology for mechanical product design, technicians must first conduct an in-depth analysis of the design parameters of the sample, use the method of 3D point data measurement, and pre-develop the product structure of the virtual prototype. Referring to the design advantages of the same type of product, the collected point data is processed to ensure that the size and hardness of each part in the product design process is in accordance with the regulations. The CAD surface construction method is used to create the post-production comprehensive modeling.
In order to ensure the scientific and reasonable way of combining parts in mechanical product design, it is also necessary for constructors to use CAD software cattle into NC programs to optimize each part standard of machinery at a later stage, organize the CAD production parameters in the early stage, generate ATL files, and split them into individual design plates, and file the text and design pictures in correspondence. If there are technical problems in the later production activities, the original design parameters of individual plates can be retrieved in time to make useful corrections and ensure the improvement of the performance of mechanical products.
2.2 Transformation of 3D models from parts to engineering drawings
The use of NC processing of molds ensures the rapid prototyping and manufacturing of modeled products. Preliminary technical testing of the molding molds is performed to ensure that the production molds meet the strength needs of the design before mass production replication activities can be carried out, thus reducing the wear and tear in product design activities to a small level.
In the product process assembly activities, the staff needs to optimize the product production process design flow, and new concepts should be incorporated for the method of tooling design. Standardized product production is implemented to reduce individual product variation in the production of standard parts, thus attracting investors to outsourced parts procurement.
For the manufacturing execution and parameter changes of modeled products, designers should consider the differences between mechanical 3D design models and solid transformations, gather the company’s designers to discuss the options for parameter changes, and finally make prudent arrangements for the change plan of product appearance design. In the process of product production size control, the parts CNC machining code should be repeatedly debugged to ensure the success of CAX integrated data collection.
In the process of PRO and other three-dimensional design software, designers need to use the casting process CAD interface software to test the pre-design of mechanical products. For the preliminary work of three-dimensional design of mechanical products, technical personnel should first read and transform the data module for performance debugging.
In the process of DXF file reading, data conversion of design parameters and 3D graphics is carried out, and the way of data interaction is defined according to the software programming. On the module of nodes, axes and their entity generation, the capture of node production methods is carried out.
In the process of 3D axis generation, technicians should use the computer for parts projection capture in addition to strengthening the simultaneous detection to prevent the problem of image superimposition leading to modeling defects in the automatic projection capture process.
2.3 Analysis of 3D solid modeling on computer
The process of three-dimensional entity modeling is the process of product manufacturing and performance testing on the computer by designers. The process of three-dimensional entity conception, designers need to use the computer three-dimensional entity modeling method, the finite element of the product for in-depth analysis. In the process of analysis, technical personnel need to split the parts in the machinery, compare the difference between its design size and three-dimensional solid process programming, and finally debug the best way to combine the parts.
Product design in the application of modern mechanical innovation design process, designers use a variety of mechanical design and production means of innovation, the green concept of mechanical design work under the guidance of the designers need to start from a global design thinking, and ultimately implemented to the local of large machinery manufacturing.
In the process of large machinery production, it is easy to appear due to partial damage to parts, resulting in the entire mechanical production activities have problems. For the same industry of different brands of machinery product design, the relevant departments must do a good job of spare parts product model parameters design uniformity design.
In the case of 3D steel frame structure rapid modeling system and production, for example, technical personnel should determine the initial design plan according to the company’s test bench design parameters as the requirements, for the mechanical products in the parts expression method and data scale integration analysis. After determining the final design plan and module import framework, the technician needs to set the process features based on the same type of modeled part entities, as well as mechanical related knowledge and relevant information.
In the process of 3D equipment body modeling and its interference checking, the specific physical parameters of the design engineering are calculated and analyzed to ensure that the output part of the design file and the drawings of 3D transformation errors are reduced to a minimum level.
Conclusion
The widespread use of three-dimensional modeling technology and the continuous development of many commercial three-dimensional design software has promoted the change of traditional design means of mechanical products. In the link of 3D modeling technology entity generation, the technical personnel should make a prediction on the effect of motion simulation of the structure, so as to ensure that there is no misalignment between mechanical entity generation and later mechanical motion. In order to achieve the best effect of the use of three-dimensional modeling technology, the entity editing module for post-debugging and necessary modifications. The modification of detail types should be carried out based on the node coordinates acquisition assignment, so that the basic shape and geometric features of the mechanical 3D model meet the needs of the product 3D expression model.
