Described space pipe support description document is meant the file of having expressed the basic parameter of all steel pipes in the pipe support of space.Document form is various, can be the file of expressing with graphic form such as autocad file etc., also can be the file of expressing with written form such as Excel file, Word file or the like.

Described steel pipe basic parameter comprises outer wall of steel pipe diameter, wall thickness, central shaft curvature of a curve and radian, residing position in pipe support.

The storage medium of described system outside is meant that mainly hard disc of computer, mobile memory, CD, network storage space etc. can be for the mediums of storage data.

Described steel pipe is residing position in pipe support, and its expression way is: under the pipe support coordinate system, and the coordinate figure of two end points of steel pipe axis.

Described pipe support coordinate system is meant and is describing all steel pipes in pipe support during residing position, a public fixedly three-dimensional system of coordinate of employing.

The geometric data of described steel pipe comprises the desirable moulding end face intersection data and the actual moulding end face intersection data of the basic parameter and the steel pipe of steel pipe.

Described steel-tube intersection-line computation schema, be meant since in the pipe support of space different its stress performances of node require and load-bearing capacity requires even contour structures requires etc. often to have nothing in common with each other, cause for different nodes, the steel pipe type of attachment each other that connects at this node place is often varied, be object for example with any two steel pipes, these two steel pipes might be that one end face is welded on the outer wall of another root, might be under the identical situation of two steel pipe radiuses, two steel pipe end faces join, and promptly end face and end face weld together or the like.When choosing different types of attachment, the data of the desirable moulding end face of the steel pipe that calculates intersection are also different so.Therefore, the steel-tube intersection-line computation schema promptly directly influences the steel pipe description of type of attachment each other of the desirable moulding end face of steel pipe intersection data.

The moulding end face of described steel pipe is meant the space curved surface that the end face at every steel pipe two ends cuts into.The forming ends face of steel pipe comprises desirable moulding end face and actual moulding end face.

The desirable moulding end face of described steel pipe, when the end face curved surface that is meant steel pipe was connected with other steel pipes, joint face did not stay the slit, fits tightly.

The design rationality of described steel pipe when the basic parameter of certain root steel pipe and desirable moulding end face intersection data all rationally the time, is judged that it is reasonable in design, otherwise is unreasonable.

Can the rationality of the basic parameter of described steel pipe be meant, according to this basic parameter, restore a steel pipe entity how much.If can restore a complete steel pipe, judge that then this basic parameter is reasonable; If can not, judge that then this basic parameter is unreasonable.The irrational situation of basic parameter comprises: the outer diameter of steel pipe≤0, exterior radius≤wall thickness are that two end points coincidences of inwall radius≤0 (inwall radius=exterior radius-wall thickness), steel pipe axis of steel pipe are steel pipe incorporeity, steel pipe axis curvature<0 etc.

Can the rationality of the moulding end face intersection data of described steel pipe be meant, according to these data, restore a steel pipe entity how much.If can restore a complete steel pipe, judge that then these data are reasonable; If can not restore a complete steel pipe, judge that then these data are unreasonable.Process by the moulding end face intersection reduction of data steel pipe entity of steel pipe is: two end points of name steel pipe are respectively first end points and second end points, this steel pipe moulding end face called after first end face that calculates according to many other steel tube place that are connected this node at the first end points place in like manner can be named second end face so.Be not difficult thus to infer that first end face should be near first end points, second end face should be near second end points.Then will keep the entity part between first end face and second end face by the steel pipe entity that this steel pipe basic parameter is ignored between the axis two-end-point endless that distance restores, promptly get the steel pipe entity that comes out by the moulding end face intersection reduction of data of steel pipe.But, if first end face is near second end points, second end face is near first end points, then the part of steel pipe entity between first end face and second end face that is restored by this steel pipe basic parameter is non-existent, on the pipe support structure of space, just be equivalent to this steel pipe and be buried in other steel pipe entities and suffered.

Described system handles result comprises the ideal of all steel pipes in the space pipe support that calculates and the cutting codes of actual moulding end face intersection data and the every actual moulding end face of steel pipe.

The NC cutting file of described steel pipe moulding end face, be meant, the actual moulding end face NC cutting file of steel pipe, be meant the intersection-line cutting machine bed is discernible, set the intersection-line cutting machine bed motion flow to control it to the data file that pipe end cuts, the steel pipe end face that cuts out is actual moulding end face.

Described jacking is handled, be meant, the cutting track of a collection of steel pipe that outer diameter is identical is arranged into delegation vertically, calculate when cutting out this batch steel pipe along these cutting tracks, spent shell total length the most in short-term, the cutting track of every steel pipe moulding end face need be around the circumferential anglec of rotation of steel pipe central axis with along the distance that moves axially of steel pipe central axis, revise the cutting track of the moulding end face of every steel pipe then according to these two data that calculate, and then describe the code of cutting track in the NC cutting file of modification steel pipe moulding end face.

Compared with prior art, space of the present invention pipe support 3D solid copying and data exception report an error and check the unreasonable place of design and make modification before function makes the user and to overlap in the actual cutting of pipe support, avoided the CAM system of traditional space pipe support to be input to the mistake that system's output is brought by the human factor of manual intervention introducing largely by system, shorten the duration, improved the reliability and stability of design greatly.Its jacking processing capacity to the moulding end face numerical control cutting codes of steel pipe has substituted user's manual jacking, and the jacking result is accurate and quick, has greatly improved raw-material utilization factor and user's production efficiency.
