After the angle for regulating each casting arm, the tools such as the cutter material removal extra by arm end is cast may be used,
The caulking groove of Core Walls Structure is vacated, Core Walls Structure is embedded in, completes the positioning of casting arm and Core Walls Structure.
Welding is carried out by the link position that will cast arm and Core Walls Structure, the link position fusing of arm and Core Walls Structure will be cast,
Casting arm is connect the splicing for completing wax-pattern by the wax solidification then melted with Core Walls Structure.It should be noted that arm and core will be cast
After cylinder connection, deburring should be carried out to the surface for the wax-pattern being spliced into and fills up processing, so that the surface of wax-pattern is complete
And it is smooth, cast out the complete and smooth rigid joint 1 in surface.
Wax-pattern is molded by the way of welding compared to bonding way, the wax-pattern gap smaller molded, and structure is more complete
It is whole, so that the cavity of the arenaceous shell molded is more complete and smooth, so as to cast out the smooth intact rigid joint in surface
1。
Splicing wax-pattern or before a splice, different labels is made on the casting arm different from Core Walls Structure angle, so as to
Go out, with markd rigid joint 1, to be equipped with the rigid joint 1 of not isolabeling in casting and forming convenient for the system of subsequent single-layer lattice shell
It makes.
Step S102, the arenaceous shell of core that manufacture matches with shape, size with evaporative pattern, i.e., to wax-pattern system
Shell.Wax-pattern is wrapped using quartz sand with after fireproof coating brushing wax-pattern when manufacturing arenaceous shell.Pass through the surface coating refractory in wax-pattern
Coating, so as to improve the refractory ability of wax-pattern, tissue wax-pattern is wrapped and arenaceous shell is poured at quartz sand manufacture by high-temp combustion, complete
Into the setting process of wax-pattern.
Step S103, cast molding go out rigid joint 1.
After manufacture wax-pattern and arenaceous shell with wax-pattern, molten steel is poured by the cast gate of arenaceous shell, molten steel is flowed to by runner
At wax-pattern, high-temperature molten steel moment causes wax-pattern to gasify rapidly, arenaceous shell short texture itself, has preferable gas permeability, gasification
Wax is discharged by the stomata of arenaceous shell, the space of former wax embryo inside arenaceous shell, it will be filled by the flowing of molten steel, ultimately form institute
The shape of the rigid joint 1 needed.
Negative pressure casting may be used in casting, negative pressure casting, be more advantageous to just having slept fills type and feeding, improves gradually
Resistance value dense structure's degree.
The rigid joint 1 of cast molding is surface-treated and is heat-treated, to promote the mechanical structure of rigid joint 1
Energy.Process annealing can be carried out for the rigid joint 1 of casting and forming, to eliminate casting internal stress, Reducing distortion cracking
Tendency.Surface hardening can also be carried out, to improve the hardness on surface and wearability or be modulated processing, with enhancing rigidity section
The integral strength of point 1 can also carry out Nitrizing Treatment, so as to further enhance the table of rigid joint 1 to the surface of rigid joint 1
Surface hardness and wearability.
Embodiment 2
The present invention also provides a kind of method for manufacturing single-layer lattice shell, single-layer lattice shell includes rigid joint 1 and rod piece 10, bar
Part 10 is connect by the linking arm 12 with rigid joint 1, so as to be connected on rigid joint 1.Rigid joint 1 uses above-mentioned system
The method of making is manufactured, and rod piece 10 is by being welded to connect on rigid joint 1, so as to form the monolayer net with surface modeling
Shell.
In the present embodiment, the method for manufacturing single-layer lattice shell includes step：
Manufacture rigid joint 1；
Space orientation is carried out to adjacent rigid joint 1；
Rod piece 10 is welded on rigid joint 1.
In structure assembly, need to carry out space orientation to the adjacent rigid node 1 of single hull structure, and faced first
When fix, thereafter, the rod piece 10 between each rigid joint 1 is lifted between adjacent rigid node 1.Rod piece 10 and rigid joint
1 first carries out progress full weld processing after spot welding positioning, this processing method, and positioning work significantly simplifies, 10 difficulty of processing of rod piece
It reduces, the labor intensity of worker similarly reduces, and the weld seam processing after rod piece 10 docks also is more convenient for operating, for realizing more
Efficiently more attractive is finally completed effect.
In all examples being illustrated and described herein, any occurrence should be construed as merely illustrative, without
It is as limitation, therefore, other examples of exemplary embodiment can have different values.
It should be noted that：Similar label and letter represents similar terms in following attached drawing, therefore, once a certain Xiang Yi
It is defined in a attached drawing, does not then need to that it is further defined and explained in subsequent attached drawing.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
Cannot limitation of the scope of the invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
It encloses.
