[Abstract]:As a kind of raw material, steel plays an important role in production and construction.Steel packaging is an important part of steel production, and the mechanical properties of locking play a key role in the quality of steel packaging.In view of the problems such as few kinds of steel baling machines and expensive cost in our country, it is of great practical significance and economic value to develop a kind of multifunctional, high efficiency and low consumption packaging equipment.In this paper, a new locking mode of steel packing machine is put forward, and the key technology of the packing machine is analyzed and studied. Finally, the whole design of the packing machine is completed.The main research contents of this subject are as follows: (1) the present situation of packaging machinery industry is briefly introduced.The main content of this subject is to discuss and study the core technology of the working head of the no-buckling and non-buckling baling machine. (2) the performance parameters of the automatic no-buckling and non-buckling baling machine are formulated, and the technological process is analyzed.The main component of the baling machine is determined. (3) the locking mechanism of the working head is studied in detail.The structural design and mechanical analysis of the locking mechanism are completed, and the kinematic simulation of the mechanism is carried out by using Adams software to optimize the main parameters of the mechanism, and through the design of the knife blade, the anti-slip scheme of the locking mechanism is discussed.Finally, the calculation of the shear force required for the biting knife is completed. (4) the mechanical properties of the non-buckling without backbuckling are studied.Based on the theoretical analysis, the mechanical characteristics and connection strength of the locking are obtained by using the Abaqus software to simulate the mechanical properties of the locking, and the connection strength is compared with that of other locking modes.The superiority of the mechanical properties of no-buckling is verified. 5) the control system of the equipment is designed.Through the detailed analysis of the process flow of the baling machine, the logic relation diagram of the control system, the electrical schematic diagram and the logic flow chart are designed.Finally, the process is divided into determined independent functional modules to achieve the modular design of the control system.
