[Abstract]:With the development of science and technology and the improvement of people's living standard, the application field of the buckler is expanding, and the special fastener is the innovation in the application field of the fastener. The production automation level and assembly ability of special fastener for ring rope have an important influence on the benefit of the company. Therefore, the methods to improve the automation level of the fastener are studied. It is of great significance to improve the efficiency of the company to study the analysis of its assemblability in the design stage of the press. In this paper, the theory of mechanism innovation design and its development trend are discussed in detail. A new type of mechanism is designed by means of combination innovation method and kinematics principle of combined mechanism, which is one of the methods of mechanism innovation design. It is applied to the bending rope mechanism of the buckling machine to realize the automation of the rope material bending. The kinematics problem of the combined mechanism is studied by using Matlab/simulink, and its mathematical model is established and solved, and the simulation model is established according to the mathematical model. The kinematic simulation and verification of the mechanism are carried out, the movement of the combined mechanism is intuitively seen, and the conclusion that the combined mechanism can meet the requirements of the bending rope of the buckler is obtained. In this paper, the technology of the buckling machine is analyzed, the structure of the die is designed, the optimum design of the die is carried out, the mathematical model of the shrinkage force of the die is established and solved, and the optimization problem is expressed in mathematical language. The optimum conical angle of the die is obtained by the mathematical analytic method, and the wrinkle phenomenon of the fastener is reduced to the minimum. This paper also discusses the present situation and development trend of the analysis and evaluation theory of product assemblability, analyzes the factors that affect the assemblability of the clamping die of the special ring rope fastener, and establishes the conceptual block diagram for the analysis of the assemblability. In this paper, a multi-level fuzzy comprehensive evaluation method is used to establish the evaluation model of the assemblability of the special fastening die for the ring rope, and the Delphi method is used to evaluate the assemblability of the clamping die of the special fastener for the ring rope.
