Description

Technical Field

[0001] The utility model relates to the technical field of engine cylinder heads, and particularly relates to a wear-resistant metal rolling product engine cylinder head structure. Background Art

[0002] The cylinder head is one of the main components of an engine. Its main function is to seal the upper part of the cylinder and form a combustion chamber together with the piston top and the cylinder. Intake valves and exhaust valves are provided on the cylinder head, and valve stems are provided in the intake valves and exhaust valves. During the operation of the engine, the opening and closing of the intake valves and exhaust valves are controlled through the valve stems to achieve the intake of fresh air or fuel gas through the intake valves and the discharge of the exhausted gas after combustion through the exhaust valves.

[0003] After retrieval, the prior art (Publication No. CN221096680U) records that "a wear-resistant ferrous metal smelting and rolling product engine cylinder head belongs to the technical field of engine cylinder heads. A wear-resistant ferrous metal smelting and rolling product engine cylinder head includes a cylinder head main body and a wear-resistant protection plate. An epoxy resin toughening plate is installed at the lower end inside the cylinder head main body. A reinforcing plate is arranged between the wear-resistant protection plate and the epoxy resin toughening plate, and a shaping notch is used to fix the reinforcing plate. The utility model solves the problem that the strength of the whole cylinder head cannot ensure the strength of the cylinder head and cannot maintain stability due to wear during long-term operation. The wear-resistant protection plate of the utility model is fixed to the cylinder head main body through a positioning groove. After fixation, the anti-slip frame body inside the wear-resistant protection plate maintains the periphery of the cylinder head main body and the wear-resistant protection plate, so that the overall shape of the cylinder head remains stable, reduces deformation during long-term operation, improves the working effect, and the strip-shaped convex layer inside the anti-slip frame body has an anti-slip and wear-resistant effect."

[0004] Although the wear-resistant ferrous metal smelting and rolling product engine cylinder head in the prior art achieves the effects of wear resistance and anti-deformation, there are still some deficiencies: When the exhaust passage involved in the existing wear-resistant ferrous metal smelting and rolling product engine cylinder head is in use, a sealing ring is usually provided around it. However, the inner side of the cylinder head is in the high-temperature environment of the engine, which may cause the sealing ring to be easily deformed and damaged. Secondly, when a general cylinder head is installed, a sealing gasket in a similar rectangular structure needs to be provided inside it. The sealing gasket exists in the connection gap between the cylinder head and the cylinder block. Therefore, during the operation of the engine, due to the friction, it is easily damaged. Although the sealing gasket itself is a consumable part, it is of further improvement significance to extend its service life. Summary of the Utility Model

[0005] In order to overcome the defects existing in the prior art, the present utility model provides a wear-resistant metal rolling product engine cylinder head structure to solve the problems that the sealing ring and the sealing gasket of the existing wear-resistant ferrous metal smelting and rolling product engine cylinder head are easily damaged due to the high-temperature environment and friction, resulting in a reduced service life.

The gasket assembly includes an epoxy resin toughening layer on the outside, and short steel bars are provided inside the epoxy resin toughening layer, and a silicone resin layer is provided inside the epoxy resin toughening layer.

[0007] Further, an outer fixing ear is provided on the outer edge of the cylinder head body, and an inner fixing ear is provided inside the cylinder head body.
