Analysis of processing advantages and core requirements of Copper sheet stamping

Compared to the scattered processing mode of traditional manufacturing, Stamping copper sheet processing has many outstanding advantages and can effectively solve the pain points of traditional processing. Traditional manufacturing is mainly based on scattered processing, and product quality and production efficiency are highly dependent on the technical level of workers. Automation is limited to the unit level, such as CNC machine tools, flexible manufacturing systems, etc; At the same time, traditional processing requires filling out a large number of material requisition forms, production forms, and process transfer forms, with a cumbersome process. Moreover, many parts are produced through a combination of self-made and outsourced processing, and the process route is uncertain. The required equipment and fixtures are diverse.

The stamping process of Custom copper stamping relies on the synergy between specialized molds and punching machines to achieve large-scale mass production, significantly reducing reliance on manual technology and improving production efficiency and product consistency; At the same time, simplifying the production process, reducing document filling, and mature stamping technology can effectively optimize the process route, reduce production complexity, and adapt to the production needs of multiple industries' parts.

As the core equipment for quality inspection of Electrical copper stamping parts, gauges are widely used in the automotive industry. Their design quality directly determines the accuracy and safety of inspection, and must comply with the five core requirements.

One is the requirement for humanization, where the measuring tool needs to balance operability, flexibility, and convenience. For large stamping parts, the adaptability of the lifting device needs to be considered to ensure the balance of the measuring tool and avoid safety accidents caused by imbalance during the lifting process.

The second requirement is material selection, with priority given to non-metallic materials such as resin, balancing portability and strength. Steel can also be used to make high-precision gauges according to customer needs, while designing the height of the gauges based on the average height of the human body.

The third is the accuracy of benchmark design. It is necessary to determine the benchmark planes in the three directions of length, width, and height based on the dimensions of the measuring tool and the position of the measured parts in the vehicle body coordinates. Combined with the installation position of the Metal stamping parts electric copper, the benchmark form should be clarified.

The fourth requirement is manufacturability. The design needs to be in line with the actual production process, considering the feasibility of production technology, and ensuring that the inspection tool can be smoothly produced and achieve the detection function.

The fifth requirement is for aesthetic appearance. Based on current aesthetic needs, while ensuring the detection function, the aesthetic appearance of the measuring tool should be improved, taking into account both practicality and aesthetics.

The design of Copper strip stamping needs to conform to the characteristics of stamping process, ensuring the feasibility of forming and product quality, mainly divided into two categories of requirements: bent parts and deep drawn parts. In the design of curved parts, the straight part of the curved edge needs to meet the requirement of H>2 δ. If a shorter curved edge is required, allowance should be reserved first, and excess metal should be cut off after bending.

When bending perforated parts, it is necessary to avoid deformation of the hole body; At the same time, the shape of Copper stamped components should be as symmetrical as possible, and the bending radius should not be less than the minimum allowable bending radius of the material. In the design of deep drawn parts, the fillet radius should be set reasonably to avoid increasing the number of deep drawing cycles, mold quantities, and production costs; The appearance should be simple and symmetrical, not too large, in order to reduce the number of deep drawing times, improve molding efficiency and pass rate.

At present, the Cross copper metal stamping market in China is oversupplied and fiercely competitive, especially with some quality issues in automotive stamping parts, mainly concentrated in three aspects.

One is surface scratches on parts, mainly caused by sharp scratches or metal dust falling into the mold, which can be avoided by grinding the mold scratches and removing metal dust.

The second issue is the cracking at the bottom of Precision copper stamping parts, which is often caused by poor plasticity of the material or excessive tightness of the mold edge ring. It is necessary to replace the material with good plasticity or loosen the edge ring appropriately.

The third issue is wrinkling on the side walls of the parts, mainly due to insufficient material thickness or eccentric installation of the upper and lower molds. It is necessary to replace qualified materials and readjust the mold clearance in a timely manner to ensure the quality of stamping and forming.
