Description

Technical Field

[0001] The utility model belongs to the technical field of burr removal devices, in particular to a burr removal device used for hardware processing. Background Art

[0002] During the processing of hardware, burrs often remain on the surface due to processes such as cutting and stamping. These burrs not only affect the product's appearance but can also cause damage to surrounding parts or personnel during use. A burr removal device can effectively remove burrs from the surface of hardware, making the product surface smoother and neater, thereby improving product quality. The presence of burrs can also affect the assembly and performance of hardware. For example, during assembly, burrs can hinder the smooth fit of parts, resulting in assembly difficulties or excessive gaps between parts after assembly. In addition, burrs can reduce the wear resistance and corrosion resistance of hardware. Deburring can eliminate these adverse factors and enhance product performance. However, existing burr removal devices have a limited grinding height and cannot completely remove burrs from one side of tall hardware at once, making them less practical. Utility Model Content
