Truss structure, the wherein crudy of steel pipe truss curved arc rod member intersection will directly determine the overall quality of engineering.It is curved at present
The conventional processing method of arc rod member intersecting mouth mainly has following two：
1. curved arc rod member elder generation Numerical control cutting intersecting mouth, then by figure curved arc；
2. process respectively and mutually pass through port and rod member main body, docked after rod member main body curved arc.
The conventional processing method of above two curved arc rod member intersecting mouth mainly has following deficiency：
1. curved arc rod member elder generation Numerical control cutting intersecting mouth, then the rod member of big bent arc radius is applicable to by figure curved arc processing method, but
Direction position and the size of well cutting intersecting mouth are difficult to ensure that during curved arc, and curved arc rod member is mutually passing through segment port press-bending
Plastic deformation can be produced during system, it is difficult to ensure mutually to pass through the design radian size of segment port.
2. process respectively and mutually pass through port and rod member main body, docking processing method is equally only applicable to big curved after rod member main body curved arc
Two ends can produce the straightway of certain length after arc radius rod member, but rod member main body curved arc, and mutually passing through port process can also produce
Raw rectilinear end, can produce rod member two ends straightway to deform after rod member docking, and mismatch and welding thermal deformation can be produced in welding process,
Influence rod member total quality and service life.
The content of the invention：
The technical problem that the present invention need to be solved is, for the deficiency of conventional background technology, in curved arc rod member intersecting mouth process
It is middle that a kind of practical bend processing method and accurate line locating template are provided, to solve conventional intersecting mouth deformation and curved arc bar
Part dimensional accuracy deviation it is big or cannot curved arc problem, positioned by the precise scoring lines of template, accurately and efficiently carry out curved arc
The processing of rod member intersecting mouth, it is ensured that the construction quality of tubular truss engineering.
Solution of the invention is：A kind of new curved arc rod member intersecting mouth processing method, it is characterised in that have following step
Suddenly：A, bending will be intended to make filled in the steel pipe straight rod member of processing river sand and by steel pipe closed at both ends, it is ensured that tube bending process
Middle steel pipe two ends do not produce straight section and intersecting mouth to deform, and control the integral curved arc of tube bending；
B, the main body and intersecting mouth of required curved arc steel pipe are separately modeled using tekla structure softwares, align linking part
Position, and telltale mark is carried out, extended to as far as possible after the length at the intersecting mouth reinforcement end 5 of the length reservation marking-off plate of main rod
Pass through a mouthful end；
C, the expansion that structure is carried out according to model, pass through mouthful end by 1:1 graphic derivation is printed to CAD, the CAD diagram that will be drawn
Shape cuts out the intersecting mouth marking-off plate of telltale mark point；
D, basis treat that the key elements such as arc length, chord length, the action of curved arc steel pipe draw position line and telltale mark the point position of welded tube, cover
Use intersecting mouth marking-off plate, rotation into alignment telltale mark point, according to the intersection 1 of intersecting mouth marking-off plate on rod member to be processed
Machining profile is drawn, now the size positions of intersecting mouth are to determine on rod member, Numerical control cutting intersection is until complete rod member processing.
Tekla Structures are the steel construction detailed drawing design softwares that Tekla companies of Finland produce.
To first intend filling river sand in the steel pipe straight rod member of bending machining and by steel pipe closed at both ends, it is ensured that tube bending process
Middle steel pipe two ends do not produce straight section and intersecting mouth to deform, and control tube bending entirety curved arc, then apply mechanically intersecting mouth marking-off plate to enter
The mark of row intersection and setting-out, intersecting mouth cutting is carried out according to the intersection for drawing, and processing obtains meeting the curved of design requirement
Arc rod member intersecting mouth.
Intersecting mouth presses 1:Intersecting mouth marking-off plate architectural feature and act on as follows that 1 expansion is obtained：Curved arc rod member intersection 1
For the machining profile line before Numerical control cutting, curved arc rod member intersection 1 ensure that the radian and chi of intersecting mouth according to material object modeling
The relative position of very little precision, the positioning intersecting mouth of telltale mark point 2 and main rod, to ensure the correct of intersecting mouth direction, curved arc bar
The size of part girth 3 will determine according to the diameter dimension of each rod member, intersecting mouth along intersecting mouth end long template cutting line 4
Launched, proper extension intersecting mouth strengthens the intensity that end 5 ensures template, and intersecting mouth strengthens end 5 to the size of intersection 1 not
Produce any interference.Positioned by the precise scoring lines of template, accurately and efficiently carry out the processing of curved arc rod member intersecting mouth, it is ensured that
The construction quality of tubular truss engineering.
