Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a stamping die for a new energy vehicle unlocking rod. Background Technology

[0002] The stamping die for unlocking levers in new energy vehicles is a precision tooling specifically designed for forming unlocking lever components for new energy vehicle doors. It primarily uses stamping processes to process sheet metal into unlocking lever parts with specific shapes and dimensions. The die employs a multi-station progressive die or single-operation die structure, including core components such as punches, dies, and stripper plates. Combined with a precision guiding system of guide pillars and bushings, it ensures accurate sheet metal positioning during stamping, meeting the assembly precision requirements of automotive parts. Its design also considers the lightweight requirements of new energy vehicles, optimizing stamping process parameters for materials such as aluminum alloys and high-strength steel. Through reasonable cutting edge design and demolding structure, it avoids part deformation and burr generation. The die integrates an automated feeding mechanism and waste collection system, making it compatible with high-speed stamping equipment, improving processing efficiency while ensuring operational safety. The die surface is treated with a hard coating to enhance wear resistance and corrosion resistance. Specifically designed for the functional characteristics of unlocking levers in new energy vehicles, the die also incorporates multiple forming processes such as bending, punching, and flanging to ensure the mechanical properties and assembly reliability of the parts. It is widely used in the mass production of new energy vehicle door systems.

[0003] A search revealed Chinese Patent Publication No. CN217726861U, which discloses a multi-pass stamping die, including a die body and a placement platform. The die body is located on the top of the placement platform, and bases are connected to both sides of the bottom of the placement platform. A support plate is provided on the base, and a mounting bracket is connected to the top of the support plate. A pedal is rotatably connected to the mounting bracket via a bearing, and a push rod is rotatably connected to the rear side of the top of the pedal. This multi-stage stamping die, through the cooperation of the mounting bracket, pedal, and ejector pin, allows for easy and convenient removal of the workpiece from the stamping die after production, saving production time and improving production efficiency. The support block and placement slot ensure the stamping accuracy of the die, preventing additional stamping marks from being left on the workpiece surface. The use of clamping plates, fixing screws, fixing clips, connecting plates, and connecting blocks allows for the fixing of dies of different sizes onto the placement table according to different production requirements, ensuring stamping accuracy. However, while this device can fix dies of different sizes onto the placement table according to different production requirements and ensure stamping accuracy, it cannot solve the problem of insufficient positioning leading to longer stamping times. Utility Model Content
