Description

A grinding wheel for automotive steel sheet rolling mills Technical Field

[0001] This utility model relates to a grinding wheel for grinding parts, specifically a grinding wheel for automotive steel plate rolls. Background Technology

[0002] Grinding wheels for automotive steel sheet rolls are the core tools for roll surface treatment. They remove oxide layers, burrs, and minor defects from the roll surface through high-speed grinding, ensuring that the roll surface flatness and roughness meet process requirements. This directly affects the thickness uniformity and surface quality of automotive steel sheets. The uniform surface texture formed during grinding can enhance the wear resistance and fatigue resistance of the rolls, extend their service life, and reduce scratches or thickness deviations in the steel sheets caused by wear. For complex contours such as grooves and curved surfaces of the rolls, grinding wheels can be customized to achieve high-precision forming, ensuring the uniformity of stress on the steel sheet during rolling.

[0003] In the prior art, document number 201922406168.3 describes a precision grinding roller resin-bonded grinding wheel. This invention belongs to the field of grinding wheel technology, specifically a precision grinding roller resin-bonded grinding wheel. It includes a grinding wheel body, an mounting layer at its center, a mounting hole penetrating through the center of the mounting layer, a protective shell on the outer layer of the grinding wheel body, a bearing at its center on the side of the protective shell closest to the grinding machine, a through hole at the center of the bearing, a cover on the edge of the bearing, an outer shell at the innermost sidewall of the protective shell, a flame-retardant layer at the outermost sidewall of the protective shell, and a sound-insulating layer between the outer shell and the flame-retardant layer. This invention, by providing a protective shell, a cover, and a sound-insulating layer, can protect the grinding wheel body and prevent dust from entering when the equipment is not in operation.

[0004] Although existing technologies can effectively block the splashing particles generated by the grinding wheel body and collect them inside the protective shell for easy cleaning, and can also effectively absorb and isolate noise and improve the working environment, the assembly and fixing between the grinding wheel and the assembly shaft is inconvenient and the assembly is not stable enough.

[0010] The assembly valve body has a main assembly component in the middle, the main assembly component is a main assembly valve stem, and the main assembly valve stem is provided with a locking pin.

[0011] Compared to existing technologies, the outer grinding wheel in this invention uses a wear-resistant alloy powder layer, significantly improving wear resistance, extending the grinding wheel's service life, and reducing frequent replacement costs. The inner and outer grinding wheels adopt a layered structure, balancing internal support with external functionality, facilitating maintenance and upgrades. The assembly valve body is embedded into the grinding wheel body through an external groove, and with the side boss threaded hole and assembly screw, multi-dimensional tight fixation is achieved, ensuring the stability of the grinding wheel during high-speed rotation. Wear-resistant gaskets are built into the top and bottom grooves to reduce frictional loss between the assembly valve body and the assembly drive shaft, while also increasing... Strong sealing prevents foreign object intrusion; the external cutting plane is tilted to improve the cutting angle, reduce cutting resistance, and improve the surface treatment quality of the steel plate; the main assembly valve stem and locking pin structure prevents core components from loosening and ensures safety at high speeds; the locking pin simplifies assembly operations and improves assembly efficiency; the modular design reduces maintenance complexity and shortens downtime; the threaded connection structure facilitates quick disassembly and reassembly; by extending grinding wheel life, reducing maintenance frequency, and improving cutting efficiency, production costs are indirectly reduced, while ensuring the stability of the automotive steel plate rolling process and product quality.
