Technical Field

[0001] The utility model relates to the technical field of punching dies, in particular to a punching forming die for an automobile reinforcement plate. Background Art

[0002] The automobile reinforcement plate is an automobile accessory used to improve the strength of individual positions or to protect certain machinery. The automobile reinforcement plate is usually made of aluminum alloy. When the automobile reinforcement plate is produced, it needs to be punched.
