Description

Technical Field

[0001] The utility model relates to the technical field of automotive leaf spring production, and particularly relates to an automotive leaf spring blanking and punching production line. Background Technique

[0002] Automotive leaf springs are the most traditional elastic components in the automotive suspension system. Due to their good reliability, simple structure, short manufacturing process flow, low cost, and the ability to greatly simplify the structure, they are widely used. Automotive leaf springs are generally composed of a group of alloy spring steels with unequal lengths, forming a spring beam approximately of equal strength. In addition to playing a buffering role in the suspension system, when it is longitudinally arranged in the vehicle and one end is fixedly hinged to the vehicle frame, it can bear all forces and torques in all directions, and determine the trajectory of the wheel movement, playing a guiding role. During the processing of automotive leaf springs, holes need to be opened on their surfaces. Currently, when opening holes in leaf springs, it is achieved by operating a cold punching female die.
