Metal hose connector model design generally have the following requirements.

Metal hose connector model design generally have the following requirements.First, the establishment of three-dimensional model of a metal hydraulic hoses connector model in order to reduce the time , to avoid excessive model features , increase computer speed, try to reduce the number of unnecessary features. Then you need the joint coordinate system is established at entrance side , because the pipeline design layout when needed , there is a reference point for the introduction , to ensure the access pipe joint sections are straight . If you do not build this pipeline design coordinates gave the inconvenience . The establishment of hydraulic flanges coordinate system when the entrance end of the principles should be followed : z -axis direction determines the direction of the wiring . The outlet end of the tube fitting , z-axis direction always points to the outside of the pipe joint and pipeline were to enter or exit parallel to the z-axis of the pipe joint . Inlet end of the coordinate system is subject to the actual installation and joints in line, in order to facilitate assembly designers , designers make use of the assembly coordinate system installed , when you need to turn a certain angle when you can take a normal installation. Note also hide some unnecessary features like reference plane , and the coordinate axes and the like; establish a reference point , and requirements placed on the axis point to the exit end face taken from the unified Outer tube fitting 1 times .
