Low-carbon steel is a commonly used base material for metal stretching, offering excellent formability, a reasonable strength-to-weight ratio, work hardening properties, and high cost-effectiveness, making it widely applicable. However, the processing characteristics of Stainless Steel Sheet Metal Stamping Sheet differ significantly from low-carbon steel, making its overall forming more difficult and placing more specific requirements on processes, equipment, and molds. It is currently a key research area in the metal forming field.
In metal stretching, material positioning and support control are fundamental. During operation, the material's stress and strain state must be fully considered, and proper constraint and fixation must be implemented. Using a flexible stripper plate with guide pillars can effectively stabilize the material's position. A reasonable mold design is equally crucial. By considering the forming characteristics of Progressive Stainless Stamping and proactively avoiding processing risks, the durability and processing stability of the mold can be improved from the source.
For sheet metal stretching, the industry has established a mature process flow, generally involving punching a bottom hole, flanging, and finally punching. The bottom hole size can be accurately calculated using professional formulas. Uneven workpiece flange height is mostly caused by unbalanced die clearance, die assembly deviations, uneven blanking force, and excessive edge burrs, all of which affect the final forming effect of the Stainless Steel Sheet Metal Stamping Parts.
Annealing can improve various defects generated during sheet metal deep drawing, but this process requires strict operating standards; operational errors can exacerbate processing problems. The industry-standard approach is to heat the workpiece to a suitable temperature and then slowly cool it in a controlled atmosphere furnace. This method optimizes the mechanical properties of the Stainless Steel Sheet Metal Stamping Sheet and reduces forming difficulty.
While high-performance stainless steel sheets are widely used in industry, their processing limitations are also significant. The workpiece surface is easily scratched during forming, and adhesion nodules can form on the die surface, damaging the finished product's appearance and hindering production efficiency. This has been a long-standing technological challenge in processing Industry Custom Small Stainless Steel Sheet Metal Stamping Parts.
Different processing conditions and product structures require matching die steels. Dies made of Cr12MoV are prone to tearing at the corners when machining drawn components with small radii. Selecting the appropriate die steel based on the product shape and processing strength is crucial to reduce wear and ensure continuous and stable machining of Customized Sheet Metal Stamping and Bending Parts.
The industry trend towards cost reduction and efficiency improvement continues to drive the optimization of drawing processes. For example, the number of drawing passes in everyday metal products is being continuously reduced, and intermediate annealing processes are being simplified or even eliminated, significantly compressing the production flow. This technological innovation has placed new and higher standards on the plasticity and formability of Steel Electrical Parts.
Using high-precision, high-rigidity stamping equipment can effectively extend the die's lifespan. It is recommended that the equipment's rated tonnage be at least 30% higher than the actual required stamping pressure. Servo presses have significant advantages in these machining scenarios, greatly extending the die's lifespan and providing reliable equipment support for high-volume Steel Welding Stamped Parts production.
After quenching, the mold retains tensile stress internally. This stress, combined with the thermal stress generated during wire EDM, easily leads to micro-cracks and shortens the mold's lifespan. Therefore, stress relief treatment is essential after machining to stabilize the mold structure and prevent mold failure during continuous Progressive Stainless Stamping processing.
The punch and die can be made of materials such as SKS3, SKD11, powder high-speed steel, and cemented carbide. Each type of steel has different strengths, wear resistance, and toughness. Even with the same material, improving the mold's surface finish and optimizing the lubrication scheme can extend its lifespan. A comprehensive material selection based on production scale and process type is crucial for long-term compatibility with the processing requirements of Stainless Steel Sheet Metal Stamping Parts.
