Description

TECHNICAL FIELD

[0001] The utility model relates to foundry processing equipment field especially relates to a brake disc casting burr removing device. BACKGROUND

[0002] The reasons for burr generation during the casting process of brake discs mainly include material properties, processing technology, mold design, casting temperature control, metal quality, and shell strength and air permeability. The plastic deformation of the material causes the edge part to stretch and tear easily during the forming process, resulting in burrs. Improper pouring speed, unreasonable mold design, and inaccurate casting temperature control in the casting process can all cause the casting material to flow poorly, which in turn leads to burrs. Poor metal quality, such as high impurity content, can also affect the quality of the casting and increase the risk of burr generation. In investment precision casting, insufficient shell wet strength, poor surface layer air permeability, and improper setting of the working parameters of the dewaxing kettle can all cause shell cracks, which in turn lead to burrs during pouring.
