Description

Technical Field

[0001] The invention relates to the field of brake drums, in particular to an automatic positioning punching device and a punching method for brake drum production. Background Art

[0002] The brake drum is an important component in the automobile braking system and plays a key role in the safe driving of the vehicle. It is a metal component shaped like a drum and is usually made of gray cast iron or ductile iron. It has good wear resistance and thermal stability. When the driver steps on the brake pedal, the brake shoe will be squeezed outward through the transmission mechanism of the brake system, so that it fits tightly against the inner wall of the rotating brake drum. Due to the strong friction generated between the brake shoe and the brake drum, this friction will hinder the rotation of the brake drum, thereby slowing down the wheels and ultimately achieving the purpose of slowing down or stopping the vehicle.

[0003] Conventional brake drum drilling processes mostly use a single mechanical positioning structure, which can only be adapted to brake drums of specific specifications.
