Description

Technical Field

[0001] The invention relates to the technical field of automobile wheel hub wire drawing, in particular to a clamp used for an automobile wheel hub wire drawing numerical control machine tool. Background Art

[0002] Wheel brushing is a surface treatment method that forms lines on the surface of the workpiece by grinding products to achieve a decorative effect. This treatment method makes the tire surface appear in two colors and has a glittering effect, giving people a dynamic feeling. This is one of the reasons why many car owners choose wheel brushing. The wheel hub is a barrel-shaped metal part that supports the tire on the inner contour of the tire. It is usually installed on the axle of the vehicle. The wheel hub can be roughly divided into two types: paint and electroplating. The electroplated wheel hub can be divided into silver electroplating, water electroplating and pure electroplating. The surface of the tire treated with wheel brushing looks more fashionable because this treatment method can increase the appearance of the tire. Compared with traditional paint wheels, tires treated with wheel brushing are more individual and unique. In addition, wheel brushing can also improve the durability and corrosion resistance of the tire and extend the service life of the tire. Therefore, many car owners choose wheel brushing as their tire surface treatment method. Wheel brushing The treated tire surface has two different colors, which makes them more unique in appearance. This treatment method forms lines on the tire surface to make the tire look more fashionable, with a jumping color effect, giving people a dynamic feeling. In addition, tires with brushed wheels can also improve vehicle performance, reduce tire friction, and improve vehicle handling and fuel efficiency. The surface of tires with brushed wheels looks more textured and high-end because this treatment method can increase the appearance of the tire. In addition, brushed wheels can also improve the durability and corrosion resistance of tires and extend the service life of tires. Therefore, many car owners choose brushed wheels as their tire surface treatment method.
