Description

Technical Field

[0001] This utility model relates to the field of silicon carbide bulletproof plate production technology, specifically to an external cylindrical grinding machine for producing silicon carbide bulletproof plates. Background Technology

[0002] A bulletproof plate is an industrial product used to protect against munitions, typically made of materials such as silicon carbide ceramics. Primarily used for bulletproof armor, bulletproof plates effectively stop various types of bullets, protecting personnel and critical infrastructure.

[0003] During the processing of bulletproof plates, the surface needs to be ground. However, since bulletproof plates have a certain curvature, they need to be ground using an external cylindrical grinding machine. External cylindrical grinding machines are the most widely used grinding machines for processing the outer surfaces and shoulder end faces of cylindrical, conical, or other shaped workpieces. They can process various cylindrical and conical outer surfaces and shoulder end faces.

[0004] Among all grinding machines, cylindrical grinding machines are the most widely used. They generally consist of a cast iron bed as the base, a worktable, a headstock and tailstock that support and rotate the workpiece, a grinding wheel head (grinding head) that mounts the grinding wheels, a transverse feed mechanism that controls the workpiece dimensions, and electrical and hydraulic systems that control the movement of the machine's moving parts. Cylindrical grinding machines can generally be classified into ordinary cylindrical grinding machines, universal cylindrical grinding machines, wide-wheel cylindrical grinding machines, end-face cylindrical grinding machines, multi-wheel head cylindrical grinding machines, multi-blade cylindrical grinding machines, plunge cylindrical grinding machines, and special-purpose cylindrical grinding machines.

[0005] Current cylindrical grinding machines are not very convenient for processing bulletproof plates. Special fasteners and other grinding accessories need to be made for bulletproof plates. In addition, the cylindrical grinding machines themselves are expensive and inefficient.

[0006] Therefore, improvements have been made to address the aforementioned issues. Utility Model Content
