The Design Of Dedicated Equipment For AP1000Nuclear Power Main Pipe Machining And Polishing

The world today with the rapid economic development and the strong industrialinnovation, leading to the enormous thirst for energy, also causing huge environmentaldamage and pollution. Therefore, a new, clean energy for the world are urgently needed tosolve the problem. Nuclear energy is the technology that is relatively mature, the mostconvenient, abundant resources and minimal contamination of clean energy, but a vital link inthe nuclear energy is nuclear safety issues, if ignored may result in more serious catastrophicaccidents.AP1000third-generation nuclear power technology is the world’s most advanced nuclearpower technology by the Westinghouse Electric Corporation in it’s previous nuclear powerdesign on the basis of major innovation in the development of a new generation of nuclearpower technology, not only the energy use of nuclear fuel increased dramatically, and mostimportantly, is a major upgrade of the nuclear security. The AP1000nuclear pipe with theoverall forging technology enables the safety of nuclear reactors is2.5times higher thanbefore casting pipe, the reactor life expectancy increased by20years. Nuclear pipe with theoverall forging technology, the head of the pipe extremely difficult, there is no equipment andprocessing methods. This issue through repeated research and design requirements on themain pipe of the AP1000nuclear power, after careful study of the bending deep holemachining process, a new follower processing elbow deep hole, with a new design of deepspace bend servo processing equipment, and the use of the most advanced workpiece reigndetection system, in charge of the pipe accurate processing.This issue to rely on national "high-end CNC machine tools and basic manufacturingequipment," special issue of major AP1000third-generation nuclear power technology in thecritical period of the nationalization process context, expand the design of the AP1000nuclearpower main channel processing polishing equipment, The paper presents a servo processingtechnology, the design of a moving beam and column machining with deep elbow exclusivesets, and fixed gantry frame structure, each axis motion detailed design; also design machineelectrical control system and auxiliary system, the machine uses SINUMERIC840D CNC;Finally, sources of interference of the host has just been analyzed and taken the appropriateanti-jamming measures.
