Description

Technical Field

[0001] This invention relates to the field of mechanical manufacturing and automation technology, and more particularly to a deburring device for folded ears. Background Technology

[0002] In the manufacturing of automotive parts, metal stamping parts, and home appliance accessories, "folded lug" type structural parts are common basic components. Their processing usually involves stamping, bending, and cutting. However, after these processes, metal burrs or plastic flash are easily generated at the edges and joints of the folded lugs, requiring grinding to facilitate further processing.

[0003] Chinese patent CN207953411U discloses a deburring device. This device uses a feeding mechanism to transport products from a storage mechanism to a turntable. The turntable rotates, sequentially transporting the products to a surface grinding station, a side grinding station, and a unloading station. The surface grinding mechanism grinds the surface of the product, the side grinding mechanism grinds the sides of the product, and finally the unloading mechanism removes the product from the turntable, thus achieving the deburring process. However, in practical use, some products of varying shapes and sizes require grinding in specific areas. The aforementioned device can only grind the surface of the product, making it difficult to perform fine grinding on specific areas. Furthermore, products of different shapes are difficult to position, typically requiring different tooling to fix the products, resulting in low grinding efficiency.

[0004] Therefore, it is necessary to develop an ear-folding deburring device to solve the above problems. Utility Model Content

[0049] When the material moves to the bottom of the grinding device 3, the fold of the material just enters between a pair of grinding wheels 34. The high-speed rotating grinding wheels 34 come into contact with the burrs on the surface of the fold and remove the burrs through physical friction. The material is continuously conveyed by the pusher 224. After the fold has completely passed the grinding wheels 34, the deburring process is completed, and the material continues to move along the conveying path to the discharge end of the conveying bed 2.
