Description

Technical Field

[0001] This utility model relates to the field of metal casting technology, and in particular to a large metal casting that is wear-resistant and not easily deformed. Background Technology

[0002] As core structural components of key equipment such as heavy mining machinery, metallurgical equipment, energy and power, marine engineering and large molds, the performance of large metal castings directly determines the service life, operating efficiency and reliability of the entire equipment. Under these extremely harsh working conditions, the castings not only bear their own huge weight, but also endure strong impact, abrasive wear and even high temperature corrosion for a long time. Therefore, it is necessary to design a wear-resistant and non-deformable large metal casting.

[0003] To this end, patent CN202137356U discloses a metal casting comprising a metal casting base in which at least one metal insert is cast. The metal insert has a torsional-resistant component profile and is attached to the metal casting base in a form-fit manner through this inlay. To simplify the production of a stable metal casting, the metal insert has an elongated shape with a longitudinal axis and an outer mold profile with a non-circular cross-section, which is truncated in the longitudinal direction by a plurality of annular grooves for fixing the inlaid metal insert in the axial direction.

[0004] Although the metal castings mentioned above can be easily connected to other metal bodies during use, they are easily damaged when subjected to impact. Therefore, it is necessary to design a large metal casting that is wear-resistant and not easily deformed. Utility Model Content

[0005] The purpose of this invention is to provide a large metal casting that is wear-resistant and not easily deformed, in order to solve the defect that although existing metal castings can be easily connected to other metal bodies during use, they are easily damaged when subjected to impact.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a large metal casting that is wear-resistant and not easily deformed, comprising a casting matrix;

[0007] A reserved groove is provided on one side of the interior of the casting matrix, and a protective structure is fixed on the outer wall of one side of the casting matrix.

[0008] A connecting component is uniformly fixed to one side of the top of the casting base;

[0009] The casting body is uniformly fixed with a casting shape on the side away from the protective structure. The interior of the casting shape is filled with a reinforcing structure, which includes a first reinforcing rib, a second reinforcing rib, and a slot. The first reinforcing rib is uniformly cast on one side of the interior of the casting shape. The second reinforcing rib is uniformly arranged on one side of the first reinforcing rib. The interior of the first and second reinforcing ribs is filled with a slot.

[0010] Furthermore, the protective structure includes an adhesive layer, a reinforcing layer, and a corrosion-resistant layer. The adhesive layer is fixed to the outer wall of one side of the casting substrate, the reinforcing layer is fixed to the outside of the adhesive layer, and the corrosion-resistant layer is fixed to the outside of the reinforcing layer.

[0011] Furthermore, the reinforcing layer is a ceramic liner layer, and the corrosion-resistant layer is a rubber layer.

[0012] Furthermore, the connecting assembly includes connecting ears, positioning plates, and connecting grooves. The connecting ears are evenly fixed on both sides of the top of the casting base. A positioning plate is fixed on one side of the top of the connecting ears, and connecting grooves are formed inside the positioning plates.

[0013] Furthermore, the connecting ears are symmetrically distributed on both sides of the casting base.

[0014] Furthermore, the first reinforcing ribs are evenly distributed inside the casting shape, and the second reinforcing ribs are evenly distributed on one side of the first reinforcing ribs.

[0015] Furthermore, the first and second reinforcing ribs interlock to form a grid structure.

[0016] The advantages of this utility model are: A large, wear-resistant, and non-deformable metal casting.

[0017] By incorporating a reinforced structure, the interlocking grid structure formed by the first and second reinforcing ribs divides the casting into multiple small units, significantly improving the bending and torsional stiffness of the structure and making the stress distribution more uniform. By opening slots inside the first and second reinforcing ribs, the overall rigidity and dimensional stability of the casting are greatly improved without significantly increasing the weight of the casting itself, achieving excellent lightweighting, reducing material usage and casting weight. This device effectively strengthens the overall rigidity of metal castings and extends the service life of this wear-resistant and non-deformable large metal casting.

[0018] By incorporating a protective structure, the corrosion-resistant layer is a rubber layer, serving as the first line of defense. This layer offers excellent corrosion resistance, noise reduction, and scale prevention, while also effectively absorbing energy from material impacts and reducing impact stress on the reinforcing layer and the casting substrate. The reinforcing layer is a ceramic liner layer with extremely high hardness and excellent corrosion resistance, directly extending the service life of the casting. The adhesive layer ensures a strong bond between the protective structure and the casting substrate, preventing the pre-reserved groove from detaching during long-term use and guaranteeing the durability and reliability of the protective effect. This device effectively protects the casting substrate from corrosion, improving the durability of this wear-resistant and non-deformable large metal casting during use. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-5 The present invention provides a wear-resistant and non-deformable large metal casting, including a casting base 1.

[0027] Reference Figure 1 , Figure 2 , Figure 4and Figure 5 A pre-reserved groove 2 is provided on one side of the interior of the casting substrate 1. A protective structure 3 is fixed on the outer wall of one side of the casting substrate 1. The protective structure 3 includes an adhesive layer 31, a reinforcing layer 32 and a corrosion-resistant layer 33. The adhesive layer 31 is fixed on the outer wall of one side of the casting substrate 1. The reinforcing layer 32 is fixed on the outside of the adhesive layer 31. The corrosion-resistant layer 33 is fixed on the outside of the reinforcing layer 32. The reinforcing layer 32 is a ceramic liner layer and the corrosion-resistant layer 33 is a rubber layer.

[0028] The reinforcing layer 32 is a ceramic liner layer, which can directly withstand most of the abrasive wear and chemical corrosion. Secondly, the corrosion-resistant layer 33 is a highly elastic rubber layer that can act as a buffer. It disperses and absorbs impact energy through its own elastic deformation, preventing the hard ceramic layer from brittlely cracking due to stress concentration. It can also adapt to certain substrate deformation. The adhesive layer 31 tightly binds the entire protection system with the casting substrate 1 into a whole, ensuring the effective transfer of the protective effect. Together, they form a long-lasting and reliable composite protection system.

[0029] Reference Figures 1-5 A connecting assembly 4 is uniformly fixed to one side of the top of the casting base 1. The connecting assembly 4 includes connecting ears 41, positioning plates 42, and connecting grooves 43. The connecting ears 41 are uniformly fixed to both sides of the top of the casting base 1. A positioning plate 42 is fixed to one side of the top of the connecting ears 41. The positioning plates 42 are all provided with connecting grooves 43. The connecting ears 41 are symmetrically distributed on both sides of the casting base 1. A casting shape 5 is uniformly fixed to the side of the casting base 1 away from the protective structure 3. The interior of the casting shape 5 is filled with a reinforcing structure 6. Structure 6 includes a first reinforcing rib 61, a second reinforcing rib 62, and a slot 63. The first reinforcing rib 61 is uniformly cast into one side of the interior of the casting body 5. The second reinforcing rib 62 is uniformly arranged on one side of the first reinforcing rib 61. The interior of both the first reinforcing rib 61 and the second reinforcing rib 62 is provided with a slot 63. The first reinforcing rib 61 is evenly distributed inside the casting body 5. The second reinforcing rib 62 is evenly distributed on one side of the first reinforcing rib 61. The first reinforcing rib 61 and the second reinforcing rib 62 interweave to form a grid structure.

[0030] The staggered grid ribs form a high-rigidity spatial skeleton structure. When the casting body 5 is subjected to load, the force can be effectively dispersed and transmitted through this dense grid network, avoiding stress concentration in local weak areas, thereby suppressing the deformation trend to the maximum extent. The hollow grooves 63 in the ribs reduce the area of ​​the thick cross section and reduce the overall weight of the casting body.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
