Study On Sawing Mechanism Of Chain Bucking Machine Based On Pro/E

Bucking machine is forestry machinery that can be sawing logs becomes certain specifications of wood. mainly undertakes the bucking work in lumberyard,Northeast Forest at high latitude, perennial cryogenic cold, Because China has not yet been applied at low outdoor jobs bucking machine. Therefore, this type of bucking machine needs to be designed to improve the utilization of the Northeast Forest timber resources. The cutting mechanism is the direct implementation part of bucking machine, the design is reasonable,which directly influences the efficiency and precision of work, so the research of cutting mechanism is very meaningful.The main purpose of this research is the sawing mechanism for in Two-dimensional design and the actual bucking problems encountered. Complete the design and analysis of sawing mechanism of3D. And Research on cutting mechanism of saw hydraulic system.First of all, introduced the development status and development trend of domestic and international the bucking machine, and summarize it, the design of the bucking machine have a overall understanding.Secondly, the bucking machine’s working environment and working requirement analysis. Determine the design scheme of each part of the mechanism. Through every part of research to understand the overall cutting mechanism, and the completion of the study the entire mechanical part.Thirdly, Pro/E software was used to design the sawing mechanism. Using the Pro/E software to the cutting mechanism of each component parts modeling. Due to the dynamic simulation of the cutting mechanism, so the use of motor assembly way to complete the sawing mechanism assembly. By defining the model, import connection and adding servo motor motion analysis was carried out on the sawing mechanism. To research the changes of position, velocity and acceleration of it. Through the introduction of model definition, quality attributes, adding servo motor and add the force/torque for the dynamic analysis of mechanism. Analysis of the use of Proe/Mechanica on the sawing mechanism parts of statics. By analysis to determine the stiffness and strength is less than the allowable stiffness and strength, so that the reliability of the parts to and understand.Finally, by analysis of the hydraulic system on the sawing mechanism, through drawing hydraulic principle diagram, the composition and working principle of the hydraulic system.
