The design of Arbor Manual Press
Abstract:Holders of this issue is to manually press-style design, working conditions for mechanical devices, were designed to press the actual job requirements. The design of presses, including gear, rack, cabinet design and a number of components, such as the choice of checking. During the design process, according to mandate the provision of the Press book length, width, height, stroke and other requirements, the completion of the design press. Stress Analysis of Press to complete the design of gear. Completion of the structure of the design of gear, you can further complete the rack design, and design Process rack. Process design of the rack, there are two programs: one-piece small batch production and mass production. According to the actual situation of the workshop process to choose the appropriate line. As the press of the fuselage structure, connecting gear with the shaft, gear shaft into the structure. At the completion of the design of gear based on the complete selection of bearings, shaft to complete the design, preparation of parts of the assembly axis program, check-axis intensity of the work requirements. Bearing on the work of press plays an important role, we should check its strength, the design of the sealing devices. In the above work is completed, press frame can be designed (box) cover the design and the design of bearings. Finally, the cost of checking should be carried out, the real cost of information processing is a data processing conversion process. The purpose of the cost of checking is to meet the mechanical requirements and processing accuracy, based on the most economical to design low-cost products.
