The following describes the method for manufacturing the 3DP component with reference to specific examples to further understand the inventive concept of the method for manufacturing the 3DP component.
Referring to fig. 1, a method for manufacturing a 3DP device includes the following steps:
s110, designing the wall thickness and the reinforcing structure of the main body of the 3DP component;
in one embodiment, the step of designing the wall thickness of the body of the 3DP component comprises: and performing shell extraction treatment on the 3DP component. Namely, the wall thickness of the main body of the designed 3DP component is subjected to shell extraction treatment on a three-dimensional model of the 3DP component, namely, the solid component is extracted into a hollow shell. In one embodiment, a shell drawing instruction is adopted in three-dimensional design software to draw a shell of the three-dimensional model of the V-shaped 3DP component, and an empty shell 3DP component with the wall thickness of 10 mm-20 mm is obtained. Therefore, on one hand, the weight of the component can be greatly reduced, the use amount of raw materials is saved, the production cost is reduced, and on the other hand, a shell with a certain thickness can be provided for hardening treatment.
In one embodiment, the step of designing the reinforcing structure of the 3DP component comprises: the inner wall of the shell of the 3DP component is provided with a conformal reinforcing rib 7. That is, the 3DP member reinforcing structure is designed by providing the shape-following reinforcing ribs 7 on the inner wall of the 3DP member housing, which can increase the structural strength of the single member and prevent the single member from being damaged due to insufficient strength during cleaning and transferring. In one embodiment, the step of designing the reinforcing structure of the 3DP component comprises: the shell back attachment surface of the 3DP member is cut away. Namely, the back surface of the shell of the 3DP component is in an open state, so that the reinforcing structure and the connecting structure can be designed in the following.
In one embodiment, the 3DP member reinforcing structure is a rib 7 disposed on the inner wall of the V-shaped 3DP member casing, and the rib 7 is shaped to be closely attached to the inner wall of the V-shaped 3DP member casing. Further, the thickness of the reinforcing rib 7 is equal to the thickness of the main wall of the V-shaped 3DP component housing, and further, the reinforcing rib 7 is provided with a rectangular reinforcing rib at the center position of the inner wall of the V-shaped 3DP component housing. Further, the height of the reinforcing ribs of the V-shaped 3DP component is flush with the back attachment surface of the V-shaped 3DP component. Therefore, the whole V-shaped 3DP component can be uniformly reinforced, and the risk of breakage of the V-shaped 3DP component shell caused by unbalanced stress due to nonuniform reinforcing structures is avoided.
S120, splitting the 3DP component into a plurality of monomer components;
in one embodiment, the step of splitting the 3DP building block into the plurality of monomer building blocks 1 includes: splitting the 3DP component housing into a plurality of production components and transfer components. Namely, the 3DP component shell is split into a plurality of parts suitable for production and transportation, and thus the single split surfaces 2 are formed on the single components through splitting. Because the large-scale sandy 3DP component is manufactured by 3DP printing, in order to facilitate printing, the shell 3DP component needs to be split into a plurality of monomer components, and the monomer components are assembled into an integral 3DP component in the later stage.
In one embodiment, a positioning structure is arranged on each single component, and each back attachment connecting corner piece is connected with the positioning structure through a clamping structure. In one preferred embodiment, a positioning structure is arranged on the splitting surface 2 of the single component, and the positioning structure is a 45-degree chamfer positioning table 8. Furthermore, rib planting holes are formed in four points of the frame of the reinforcing rib. Furthermore, the positioning structure is a concave-convex positioning table arranged on the splitting surface, the clamping structure is a clamping fixing groove, and the clamping fixing groove is provided with a rib planting hole or a clamping groove. This facilitates subsequent assembly of the unitary member 1 into a complete 3DP member.
S130, cleaning the surface of each monomer component and performing glue permeation and hardening treatment;
that is, the surface cleaning is an operation of cleaning the single-body member 1, specifically, cleaning loose sand and floating sand on the surface of the sandy single-body member, specifically, air blowing with a certain pressure or brushing, and the like may be adopted.
In one embodiment, the step of performing a bleeding hardening process on the surface of each single member includes: a high-strength resin is applied to a surface of each of the monomer members. Namely, the glue hardening is to apply a high-strength resin to the surface of the sandy single component, the hardening degree of the single component is related to the penetration depth of the high-strength resin, and the deeper the high-strength resin penetrates into the shell wall of the single component, the better the strength of the single component shell, that is, the better the hardness of the single component, namely, the requirement of the sandy 3DP component in the field of architectural decoration can be met.
S140, designing a plurality of back-attached connecting corner pieces;
namely, the back-attached connecting corner piece is used for connecting and fixing the single components to form an integral shape, and meanwhile, the integral rigidity of the shell 3DP component is increased. In one embodiment, the back attachment corner fittings include at least any two or more of micro-bent tubes 5, chemical rivets 6, steel corner fittings 3, and anchor ears 4 that are cooperatively connected to one another. Namely, the back attachment corner connector comprises a micro-bent pipe 5 and a chemical rivet 6 which are mutually matched and connected; the back-attached corner connecting piece comprises a micro bent pipe 5 and a hoop 4 which are mutually matched and connected; the back attachment corner connecting piece comprises a micro bent pipe 5, a chemical rivet 6 and a hoop 4 which are mutually matched and connected; the back attachment corner fitting comprises a micro-bent pipe 5, a chemical rivet 6 and a steel corner fitting 3 which are connected in a matched mode. Specifically, the micro-bent pipe is a steel pipe fitting. In particular, the 3DP component is provided with a fixed foundation connected with a building surface, so that the stability of the installation of the 3DP component is ensured. Specifically, the hoop 4 is a U-shaped hoop. Specifically, the micro-bent pipe 5 is connected with a chemical riveting bolt 6, a hoop 4 and a steel corner fitting 3 in a matching manner, the chemical riveting bolt is implanted into a bar implanting hole, the hoop clamping position surrounds the micro-bent pipe, and the steel corner fitting is fixed by a nut, penetrates through the chemical riveting bolt and the end of the U-shaped hoop after a 3DP component is aligned with the U-shaped hoop; thereby achieving the purpose of integrally stabilizing the housing 3DP member.
And S150, assembling the single components into a 3DP component by adopting the back-attached connecting corner piece.
In one embodiment, the step of assembling each single component into a 3DP component by using the back-attached connecting corner fitting includes: numbering each monomer component, and assembling the monomer components according to the numbers in sequence. The single component installation is to assemble the single components on the micro bent pipes of the 3DP component according to numbers in sequence, specifically, the single components are assembled from small to large according to the component single number, specifically, the single components are hoisted and fixed at a set position, each micro bent pipe is connected and fixed, and other single components are assembled one by one according to the structure of the 3DP component and according to the preset clamping and positioning positions.
In a specific embodiment, the micro-bent pipe 5 is fixed on a building foundation according to a construction drawing, and the single component 1 is assembled on the 3DP component micro-bent pipe 5 in sequence from small to large according to the drawing number. Specifically, a 1# V-shaped monomer component and a micro-bent pipe 5 are installed in an aligned mode, and then the components are installed on the micro-bent pipe 5 in a matched mode with a 45-degree chamfer positioning table 8 from small to large according to numbers in sequence; and the operation is carried out until the whole V-shaped 3DP component is assembled. Preferably, in order to accurately obtain the required monomer components during assembly, the monomer components 1 can be numbered during disassembly and assembled by contrasting a disassembly blasting diagram during assembly, so that the assembly speed can be increased, and rework after assembly errors can be avoided.
According to the manufacturing method of the 3DP component, the weight of the 3DP component is reduced and the strength of the 3DP component is enhanced through the reinforced design by designing the wall thickness and the reinforced structure of the main body of the 3DP component; meanwhile, the strength and the resistance of the 3DP component are further enhanced by carrying out surface treatment and glue permeation hardening treatment on the split monomer components; further, by designing the back-attachment corner connecting piece, each single component can be reliably assembled into the integral 3DP component through the back-attachment corner connecting piece, and the rigidity of the 3DP component is effectively improved.
