Roll bending type CAD systems and the development of the British Rodes, who pay
Interactive roll bending system based CAD CAD system of three roll steel
System, mainly by the production of empirical data to support, lack of integrity management system
On the system, but a computerized design experience.
Germany CO PRA system, Roll forming machine Australia CADRO F system,
British ORT IC system is more robust and foreign representative
Roll CAD system. These systems were large-scale commercial software, power
Can more versatility. However, the design of the factory workers, seems designed the
Process complex, cumbersome, design thinking, design theory of transparency is not high, Design
Inflexible, it is difficult, in light of the actual situation on the system
Amended and improved, it is difficult to fully play designer ingenuity.
Beijing University of Science and Technology Shanghai Institute of Iron and Steel, Wuhan Iron and Steel
Design and Research Institute, Northeastern University, Beijing Metallurgical Equipment Research Institute, Yanshan
University are carrying out computer aided design in the roll forming should be
With research and has developed several sets of roll CAD system, and some have been
The production, good results. However, there are still some shortcomings
For example, do not form a complete and systematic body of basic theory Roll Forming
Department; in experimental research, roll forming, because of poor experimental conditions, accuracy
Is not high, does not accurately reflect the actual production situation; in Roll Forming
CAD software system design, to save manpower, material and financial resources
The premise of self-developed compact, easy to use commercial software
Pieces, Roll former and make inexpensive, easy to use at home to promote. Above
These aspects require further efforts.
CA E 313 molding process technology trends
Roll bending system and the roll of flexible CAD CAD expert system
Now roll CAD technology trends.
Flexible System (F lex ib le System) is a manufacturing
A research focus. In the field of roll forming, tool design often follow the
Maximum use of the original roll design principle of the production of new varieties of rolling
Roll. Formally proposed to roll production as a flexible system so that as much as possible
Saving tool, the cost for roll number and time, improve productivity, is the roll
Forming a big step forward in the field. Flexible system can be used to save roll,
Full use of the original roll, with obvious economic benefits.
Roll Forming is a complex process of plastic molding, simple
Difficult to describe with a mathematical model, AI and expert systems
Direction to solve this problem. The roll bending process design experience of experts
Knowledge can be effectively collected to form a knowledge base, plus a reasonable
Inference engine, the establishment of roll design expert knowledge systems, according to
Depends on certain mathematical models and reasoning rules, the development roll forming Road
Time and deformation process, to achieve roller spent on Automatic Generation and Optimization
Designs, which will roll forming tools greatly simplify the design, efficiency is greatly
Increase, especially for more complex products section. Wuhan Iron and Steel University
Institute, Hebei Institute of Chemical and Light Yanshan University to develop their own software
System, for inclined spiral roller ball rolling pass design and simple off
Pass Design steel surface.
Roll forming further study the theory of computer simulation
Technology in roll forming, drawing and design information home and abroad have
Production experience, a reasonable mathematical model and the mechanical model to roll
Molding product design and process arrangements to establish the basis for scientific analysis
On; both numerical simulation results based on computer graphics
Method of molding process and mechanical information displayed, suggesting possible changes
Defects, the final image to provide users with intuitive and easy to learn hand
Section, to guide production.
4 Conclusion
By contrast, detailed analysis and evaluation of the roll forming process
Technology development, forming and molding process theory CA E Technology
Progress of the system to understand and master the roll forming research and development like
Situation has a certain reference value.
