Design And Research On The Ceramsite-reinforced Block Dual-axis Cutting Machine

With the increasing national infrastructure, there is a vast demand for blocks. Ceramic reinforced blocks are wall blocks with a relatively new stage of self-insulation materials. Currently, the domestic production equipment of block made for different requirements focuses on improving production efficiency and reduces production costs. In block production line, block cutting is the important part. The design and research of ceramic reinforced blocks cutting machine is helpful to improve the levels of block production and the country’s development machine.This paper is based on the design of ceramic reinforced block production line, and it has designed biaxial cutting machine. According to the problems of traditional companies’ cutting machine, designing a new type of cutting machine is to meet industrial requirements. After completing the three-dimensional design, it analyzes the mechanical models of cutting process. The analysis static and dynamic is to verify the correctness of the design. The optimization of the posts and the shaft of saw is to determine the optimal design variable values. The main contents are as follows:(1) According to the characteristics of ceramic production and processing of concrete blocks, it determines the overall functional requirements of cutting machine and research the relationship between the various functional modules of machine, in order to design a program to meet the requirements of the machine structure, and complete 3D models.(2) This paper explores the mechanism of sawing through the change of the workpiece surface, during diamond saw blade in the study process. The cutting force of the sawing process is divided into the normal cutting force and the tangential force. It selects the cut sawing along the way, based on the distribution of power. Through analysis of the blade force, it establishes some mathematical models of the cutting area, and is coupled to a plurality of blades cutting force suffered. Through analyzing the relationship between the actual length of sawing zone and angle of area, it establishes relationships between sawtooth and cutting depth. Then it establishes a mechanical model of a single diamond for the forces.(3) According to the sawing process mechanics model, it analyzes the distribution of loads in various key parts of the machine, and establishes a corresponding finite element model of the key parts, then analyzes their static. Based on each of the analysis results, it improves corresponding programs, in order to improve its performance. For dynamic analysis method, it researches natural frequencies and mode shapes of machine, to verify its stability work.(4) Based on the results for the important parts of the machine, it optimizes the axes and posts. Through selecting the appropriate design variables, constraints and objective function, it has analyzed and optimized the axes and posts.In this paper, it has designed biaxial cutting machine through functional requirements analysis. It researches and analyzes for the important components, and optimizes the structure the key parts. This provides a theoretical basis for the design and optimization of cutting machine.
