A forming die set is a critical component of a Case Forming and Drawing Press, consisting of matched upper and lower dies that work together to transform flat sheet metal into three-dimensional casings or enclosures through drawing and forming operations. It provides the precise contours and dimensions required for the final product. The die set is designed for high-volume production, with materials such as tool steel, carbide, and high-speed steel ensuring durability and wear resistance. Key parameters include die height (150–400 mm), die set weight (500–3000 kg), working area (300×300 to 800×800 mm), operating pressure (1.0–1.6 MPa), maximum force (50–200 kN), stroke length (50–150 mm), guide pillar diameter (20–50 mm per GB/T 2861.1), guide pillar count (2–4), parallelism accuracy (±0.02 mm per ISO 1101), surface hardness (58–62 HRC per ASTM E18), material grade (Cr12MoV per GB/T 1299), and operating temperature (-20 to 80°C). These values are reference ranges and must be verified for the specific model and application. The die set operates by positioning sheet metal between the upper (punch) and lower (die) components. When the press activates, the upper die descends with controlled force, pressing the metal into the lower die cavity, stretching and forming the material through plastic deformation while guiding material flow to prevent wrinkles or tears. Selection inputs include press shut height, required forming force, part size, and draw depth. Verification questions should address compatibility with the press, material specifications, and adherence to relevant standards. Maintenance signals include excessive wear, misalignment, or surface damage. Failure boundaries include operating beyond rated force or temperature, which can lead to premature failure. Always confirm model-specific values and standards with the legal manufacturer or supplier.
