Blanking metal stamping die for sheet metal parts

　　Blanking Metal Stamping Die for Sheet Metal Parts

　　When selecting or customizing a blanking metal stamping die for sheet metal parts, the core factors to prioritize include die structure type, material selection (die & sheet metal), blanking precision, service life, and compatibility with stamping equipment. Below are recommended die types with their core features, tailored for various sheet metal blanking scenarios such as automotive parts, electronic components, home appliance accessories, and hardware fittings:

　　Single-Station Blanking Die for Simple Sheet Metal Parts

　　A basic and widely used die type, mainly suitable for blanking simple-shaped sheet metal parts (such as circles, squares, rectangles, and regular polygons) with low precision requirements. It adopts a single-station structure, completing one blanking process per stamping stroke, featuring simple structure, easy manufacturing, low cost, and convenient maintenance. The die frame is made of high-quality cast steel or 45# steel, ensuring overall rigidity; the punch and die are made of Cr12MoV or SKD11 high-speed steel,经过 quenching and tempering heat treatment, with hardness reaching HRC 58-62, ensuring wear resistance. It is equipped with guide pillar and guide sleeve for precise guiding, reducing the deviation of punch and die during stamping. Suitable for small-batch production of sheet metal parts with thickness ranging from 0.5mm to 6mm, such as hardware gaskets, electronic component shells, and home appliance mounting plates. The blanking gap can be adjusted according to the sheet metal material (mild steel, aluminum alloy, stainless steel) to ensure smooth blanking section and reduce burrs.

　　Compound Blanking Die for Precision Sheet Metal Parts

　　A high-precision die type that integrates blanking with other processes (such as punching, bending, and forming) in one station, completing multiple processes in a single stamping stroke. It is mainly suitable for complex-shaped sheet metal parts with high precision requirements (dimensional tolerance ≤±0.02mm) and high surface quality requirements. The punch and die adopt a multi-structure design, with strict coaxiality and parallelism requirements; the material is selected from DC53 or ASP23 powder metallurgy steel, which has higher hardness (HRC 60-64) and wear resistance than traditional die steel, and the service life is increased by 2-3 times. Equipped with a precise floating guide mechanism and a pressure plate device, which can press the sheet metal before blanking to prevent material displacement and ensure blanking precision. The die is also equipped with a waste discharge mechanism to avoid waste accumulation affecting stamping efficiency. Suitable for mass production of precision sheet metal parts such as automotive engine gaskets, precision electronic connectors, and instrument panel parts, with sheet metal thickness ranging from 0.1mm to 3mm. It has the advantages of high production efficiency, good part consistency, and reduced subsequent processing procedures.

　　Progressive Blanking Die for Complex Sheet Metal Parts

　　A high-efficiency die type composed of multiple consecutive stations, where the sheet metal strip is fed step by step, and each station completes a partial blanking or forming process, and finally obtains the finished part at the last station. It is suitable for blanking complex-shaped, multi-process sheet metal parts with high production efficiency requirements. The die is equipped with a precise feeding mechanism (such as roller feeding or pin feeding) to ensure the feeding accuracy of the sheet metal strip (positioning accuracy ≤±0.01mm); each station is equipped with independent guide and pressure devices to ensure the stability of each process. The punch and die are designed with modular structure, which is convenient for replacement and maintenance; the material is selected according to the sheet metal hardness, for example, for stainless steel sheet metal, high-wear-resistant SKH-9 high-speed steel is used. Equipped with a safety protection device (such as a photoelectric protector) to ensure the safety of operators. Suitable for mass production of complex sheet metal parts such as automotive door hinges, mobile phone middle frames, and hardware tools, with sheet metal thickness ranging from 0.2mm to 5mm. It has the advantages of high automation, high production efficiency, and low labor cost, and can be matched with automatic stamping production lines.

　　Fine Blanking Die for High-Strength Sheet Metal Parts

　　A specialized die type designed for blanking high-strength sheet metal materials (such as high-strength steel, titanium alloy, and spring steel) and sheet metal parts requiring a smooth blanking section (surface roughness Ra ≤0.8μm). It adopts the principle of three-way pressure blanking, with a V-shaped ring on the pressure plate and a counter punch at the bottom of the die, which can apply lateral pressure to the sheet metal during blanking, prevent material tearing, and obtain a flat and smooth blanking section. The die frame is made of high-strength alloy steel, with strong bearing capacity; the punch and die are subjected to deep cryogenic treatment to improve hardness and toughness, reducing the risk of chipping. Equipped with a precise hydraulic pressure control system to adjust the blanking pressure and speed according to the sheet metal material and thickness. Suitable for the production of high-strength sheet metal parts such as automotive safety parts (seat belts, airbag components), aerospace parts, and precision mechanical parts, with sheet metal thickness ranging from 1mm to 8mm. Although the die manufacturing cost is high, it can greatly improve the quality of high-strength sheet metal parts and reduce the need for subsequent grinding processes.

　　Customized Blanking Die for Special-Shaped Sheet Metal Parts

　　A personalized die type tailored for special-shaped sheet metal parts with irregular shapes (such as curved surfaces, special holes, and asymmetric structures) that cannot be processed by standard dies. The die structure is designed according to the 3D model of the special-shaped part, with targeted punch and die shapes. The material selection is flexible, and high-performance die steel or non-metallic materials (such as polyurethane) can be used according to the sheet metal material (soft materials such as aluminum alloy, copper alloy) and processing requirements. Equipped with a special positioning mechanism to ensure the accurate positioning of the irregular sheet metal during blanking; for thin-walled special-shaped parts, a flexible pressure plate is used to avoid material deformation. Suitable for small-batch production of special-shaped sheet metal parts such as custom furniture accessories, medical equipment parts, and special equipment components, with sheet metal thickness ranging from 0.3mm to 4mm. The design and manufacturing cycle is relatively long, but it can meet the special processing needs of non-standard sheet metal parts, ensuring the accuracy and shape consistency of the parts.
