This invention provides a pressure-stabilizing stamping die device for processing automotive parts, belonging to the technical field of automotive parts processing molds. The device includes an upper die plate, a lower die plate, a bottom support plate, an upper die assembly, and a lower punch assembly. A first nitrogen spring, a second nitrogen spring, and a third nitrogen spring are fixed on the bottom support plate. The first nitrogen spring is located at both ends of the bottom support plate, with its upper end connected to both ends of the upper die plate. The upper end of the second nitrogen spring passes through a drawing and pressing plate and abuts against a wear-resistant block. The first and second nitrogen springs are connected by an air pipe. The upper end of the third nitrogen spring is connected to the lower end of the drawing and pressing plate. Connecting the first and second nitrogen springs through the air pipe enables coordinated adjustment of the stamping pressure. When the downward pressure of the upper die plate is too high, nitrogen can flow between the two nitrogen springs, reducing the pressure of the corner pressure plate in the reverse direction, effectively preventing the material from failing to flow into the cavity due to excessive pressure.

This utility model discloses a wire clamping mechanism for a wire storage drum, comprising: a wire storage drum and a wire clamping mechanism. The wire clamping mechanism includes: several end caps and several wire clamping assemblies. The end caps are provided with several piston chambers, and an inner cavity is formed on the inner side of the end caps. The wire clamping assembly includes a piston element, a wire clamping plate, and several elastic elements. The piston element is provided with piston end one and piston end two. The driving assembly includes a driver and rollers. In this utility model, the wire clamping assemblies are located at both ends of the wire storage drum, reducing vibration caused by imbalance and making the dynamic balance and circular runout of the wire storage drum more stable. Both the wire clamping assemblies and the driving assembly are located outside the wire storage drum, allowing the structure of the wire clamping assemblies and the driving assembly to be directly observed, facilitating problem finding and debugging and maintenance. Furthermore, when the elastic elements of one set of wire clamping assemblies experience metal fatigue, the driving assembly can drive another set of wire clamping assemblies to clamp or loosen the wire, reducing the number of maintenance operations, reducing downtime, and improving production efficiency.
