Abstract
The invention discloses a technical method for sand mould modelling for a hollow sphere cast steel node, comprising the following steps: drawing a line of intersection on a sphere according to an adapter tube center position marked by a sphere external mould, the radius of the adapter tube and the radius of the line of intersection of the sphere; drilling two to three connection screw holes along the center direction on the center position of the end surface of the core print of the adapter tube external mould; fixing the external mould of the adapter tube on the sphere external mould by a long bolt; constructing the upper box and the lower box of the hollow sphere cast steel node and the inner sand core of the adapter tube; assembling and fixing the inner sand core of the adapter tube; combining the inner sphere core; checking a core assembling effect; and carrying out mould assembling. The method disclosed by the invention has the popularization meaning on manufacturing hollow spherical cast steel nodes in structural modes, such as sand mould modelling hollow spheres, semi-hollow spheres, adapter tube hollow spheres and the like and has a wide application prospect.
Description
Technical field
The present invention relates to a kind of foundry engieering, particularly a kind of technical method for sand mould modelling for hollow sphere building cast steel node.
Background technology
The building cast steel node is the joint form of modern large-scale steel structure extensive use, and according to the CECS235:2008 industry standard, the primary structure form has five large classes: (1) intersecting pipe node; (2) cast steel hollow spherical joint; (3) gusset-type joint; (4) cast steel hinged joint; (5) combined joint sphere nodes.Because the sphere nodes surface structure is attractive in appearance, be adapted to spacial multi-angle, the position of joints of taking over more.For the building node of diameter less than Φ 200, the operations such as welding are cut, taken in general employing sphere forging forming, adapter position at present, for large-diameter hollow ball building cast steel node, and the present domestic sand mold manufacturing experience that there is no.
Summary of the invention
Technical problem to be solved by this invention provides a kind of technical method for sand mould modelling for hollow sphere building cast steel node, can be suitable for hollow ball, in midair hollow ball cast steel node water-glass sand or the phenolic sand molding of dissimilar many specifications kinds such as bulbus cordis, adapter type hollow ball.
For the purpose that realizes solving the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of hollow sphere building cast steel node phenolic sand molding process of the present invention, the method may further comprise the steps:
The first step, take over center position and adapter and sphere intersection radius according to the 1# that identifies on the external mold sphere and draw intersection at the sphere external mold;
Second step, take over external mold core print end face along axis direction at 1#, bore 2 ~ 6 attachment screw holes;
The 3rd step, contrast intersection position adopt the stock screw that 1# is taken over external mold and the sphere external mold is fixed installation;
The 4th step, the repetition first step～3rd step are fixed on other adapter external mold on the drawing on first sphere with screw;
The 5th step, make first sphere external form of hollow ball cast steel node, behind the sand solidified, remove all and take over external mold hold-down screws;
The 6th step, the repetition first step～5th step are made second sphere external form;
The 7th the step, at upper and lower sand mold surface of internal cavity spary high-temperature resistant coating;
The 8th goes on foot, makes hollow Internal Spherical Surface core and take over interior core: at core outer surface spary high-temperature resistant coating;
Hollow Internal Spherical Surface core is installed in the 9th step, combination, with the fixing core print of binding agent;
The tenth step, check core assembly effect;
The 11 step, mould assembling.
The high-temperature resistant coating of surface of internal cavity spary, preferred paint thickness is 1.0～1.5mm.
The high-temperature resistant coating of core outer surface spary, preferred paint thickness is 1.0～1.5mm.
A kind of technical method for sand mould modelling for hollow sphere building cast steel node of the present invention especially is suitable for the manual hollow ball cast steel node of single-piece formative technology.
Described 1# takes over as the foundation location of hollow ball external mold sphere and takes over, and other adapters can position according to the relative position relation with the 1# adapter.
These technical schemes also can make up mutually or combination, thereby reach better technique effect.
By adopting technique scheme, the present invention has following beneficial effect:
A kind of hollow sphere building cast steel node moulding process of the present invention, solved domestic hollow ball cast steel node formative technology, can be used for hollow ball, the in midair hollow ball shape cast steel node manufacturing of the versions such as bulbus cordis, adapter hollow ball, have dissemination, application prospect is very wide; Adopt domestic certain airport of method of the present invention 90 kinds of specification Φ, 800 large-diameter hollow balls building cast steel node to carry out moulding, implementation process is smooth, and surface quality reaches Sa25, is higher than the general manufacture level Sa25-Sa50 of industry; Casting dimension accuracy reaches the GB/T6414CT9-CT12 level, is higher than the horizontal CT13～CT15 of general industry; Sphere take over center line angle error with the attached chi precision metering of angle less than ± 0.02 °, be lower than that industry standard requires ± 0.25 °.
