Description

Technical Field

[0001] This utility model relates to the field of automotive door hinge manufacturing technology, specifically a protective structure for an automotive door hinge sawing and milling composite machine. Background Technology

[0002] As a key automotive component, door hinges require high-precision machining using a saw-milling machine. This machine combines sawing and milling functions, enabling efficient machining of complex shapes, but it generates a large amount of metal shavings and dust during the process.

[0003] If metal scraps and dust are not cleaned up in time, they will scatter onto equipment and workshop floors, causing accumulation of scraps and dust. This may jam mechanical parts, leading to decreased equipment precision or shutdown. The metal particles and dust in the scraps will pollute the workshop environment and endanger the health of operators. Current cleaning methods mostly rely on manual cleaning at regular intervals, while using a dust collection system to collect some of the dust. However, this reliance on operators for regular cleaning requires machine shutdowns for safety, resulting in reduced production efficiency. The dust collection system has weak adsorption capacity for dust falling on the equipment and is prone to clogging pipes. Utility Model Content
