This utility model discloses a punching die for automotive parts, relating to the field of automotive parts processing technology. It includes a base, a workpiece conveying unit, and a punching unit. Through an arched top frame design, the five columnar mounting seats are arranged in an arc shape, ensuring that the hydraulic cylinders and punches at each position are vertically aligned with the punching points on the curved surface of the automotive parts. By ensuring the punches are perpendicular, dimensional deviations or increased burrs in the punched holes are avoided. Furthermore, the arched frame is easy to disassemble; by replacing different top frames, the punching assembly can be installed in different positions to produce different types of automotive parts. It also features a reliable workpiece conveying unit, capable of effectively installing and fixing curved workpieces such as automotive bumpers, and moving the workpiece from front to back to sequentially complete loading, punching, and unloading operations, effectively improving automation and processing efficiency.
