The Production Technology And CNC Special Processing Equipments' Design And Research Of The Panel Furniture Drawer Process

With the continuous improvement of people's living standards, the material requirement of the drawer productions is mainly consist of solid wood and artificial panel. However, the cost of solid wood furniture manufacturing is relatively high, which can neither meet the demands of most public customers, and the mass process of its market demand is slow. Oppositely, with the rapid development of the panel furniture processing technology and the improvement of processing accuracy, the quality of the panel furniture has been improved constantly and wins most users'favor.This set of panel furniture drawer processing has three CNC machine tools. In this paper, one of the special processing equipment is discussed in detail. It is based on the multi-spindle, multi-turret, multi-operation composite processing technology. Some processes can be realized at the same time in the processing after the parts to be processed through the movable center position fastening device, both improving the processing efficiency of products and the accuracy. It can accomplish a number of processes with one-time fixture, reducing the inaccuracy brought by the repeatedly clamping, positioning and tool setting.According to the characteristics of the drawer with size standardization, serialization, and mass production in China's panel furniture industry, the relative optimized process route has been adopted to determine the components of the whole drawer processing. Manufacturing procedures have been arranged reasonably in this CNC drawer processing and mainly adopting the CNC machine in individual process. Using the sheet metal drawer with dedicated processing equipment to ensure that the relative errors between the processing position of the sheet is small. It reduced the accumulation of the processing errors, and also increased the whole assembly precision of the drawer. In the premise of meeting the corner's strength and the bonding properties, triple connector should be adopted between the plates of the panel furniture drawer which composed by suppository, bolt, and eccentric pieces. A dedicated processing line of the CNC drawer should have been designed combining many processes such as drilling, milling and so on, taking the application of the advanced manufacturing technology for reference at the same time, in order to maximize the degree of automation of the specialized equipment, reduce the labor intensity and improve the efficiency of the whole process.CNC machine tool is a multi process machine processing. It's not just a simple accumulation of the processes, but an innovation development by optimizing the existing traditional process and machine configurations. The equipment in this processing is a complex and multi-process machine working on a single machine tool.Finally, this article discusses the compositions of the CNC special processing equipment in this process, using Pro/E to simulate the animation of the drawer's production procedure and to check that whether there is interference among the parts and components through the video simulation.
