23 < br> Design General Information
This design is a large pipe intersection Cutting the design, including numerical control systems, mechanical structures and the design of the flame gas. As human understanding of ocean depth and the development of accelerated development, human gradually from the sea near the seashore to browse areas of shallow water to deep water areas of the transition, as the human understanding and learn of marine resources, the work of the platform - platform, which is widely applied. It is a jacket by a large number of intersecting connections, so If we can design a certain precision, a relatively high degree of automation to achieve the cutting machine cut the pipe will have important significance. This machine's overall design is based on mathematical parameter model intersecting line cutting machine, cutting torch and the trajectory of film analysis based on decomposition of the cutting torch rotary movement, pan torch, torch cutting torch swing angle and the radial amends Axis, and pipe welding groove intersecting movement of CNC cutting, ultimate completion of the intersection Cutting Machine. This design is mainly the design of gas on the flame, the other, the mechanical structure design part of the torch on the realization of the T-axis tilt angle is also one of the design. As the stepper motor speed only depends on the pulse frequency simple to control, and fewer errors, so the T-axis can be driven by a stepper motor. designs contain the mathematical model, the overall program to determine, on the coupling, electrical, pendulum shaft and additional parts of the design verification, and the gas line design.

INTRODUCTION
This current devise is about the cutting apparatus because large-scale pipe intersecting line, including digital systems, mechanical structures and gas blaze road design. With human beyond comprehending of the ocean and accelerated evolution of sea reclaim, human reconnaissance of the ocean are gradually from shallow water near the coastal areas to deep conversion places. As the platform of people knowing of navy resources and research work - marine platform, its petitions will chance wider. It was made at a great digit of catheter - a intersecting link, therefore, to design cutting machine with a decisive precision and relatively high degree of automation to effect the cutting of steel tubes will have major meaning. The overall design of the machine tool namely based on the algebraic model of intersecting line and the analysis of the pathway of cutting torch. The cutting campaign was divided into 4 axis comparative motions of cutting torch, ie rotate circular the pipe, shift forward pipe, swing and recompense onward radial instruction. The design studies NC cutting movement as welding groove of pipe intersecting, then finishes the design of pipe intersecting line cutting device. This design is chiefly for the gas flame road design, in addition, the mechanical structural design, namely the design of T-axis for achieving the swing of cutting torch, is likewise 1 of the duties. Since the rotational speed of step motors only depends aboard pulse frequency, with a convenient control and fewer error, the T-axis tin be driven at step motors. The contents of the design concludes the establishment of mathematical model, the design of the entire scheme, the design and correction of the the parts such for shaft coupling, step motor and swing-axis, as well as gas road design.
