Briefly introduce: what are the technical points of processing precision metal stamping parts for electrical terminals?

The core of machining precision metal stamping parts for electrical terminals is to ensure dimensional accuracy, stability and consistency.

Key technical points

Die design and manufacture: adopt high-precision die (tolerance ≤±0.005mm), the gap between convex and concave die matches the thickness of material, and the cutting edge needs quenching and nitriding to improve wear resistance.

Material selection and pretreatment: Phosphor bronze, brass and other materials with good electrical conductivity are preferred. Before processing, oil stain and scale should be removed, and annealing and softening are necessary.

Stamping process control: adopt multi-station continuous die to realize integrated processing, control stamping speed (usually 100-500 times/minute), and ensure material positioning accuracy through feeding mechanism.

Quality inspection and calibration: the key dimensions are inspected by two-dimensional imager and three-coordinate measuring instrument, and the mold and equipment parameters are calibrated regularly to avoid accumulated errors.
