When it comes to crafting electronic precision stamped components, a meticulous process unfolds, resulting in the creation of intricate and high-quality pieces. In this article, we delve into the step-by-step journey of producing these remarkable components, shedding light on the techniques and considerations that ensure precision and excellence.
Initial Steps: From Shaped Rings to Die Cavity
The journey commences with the careful placement of a shaped ring onto a guide plate, positioning it near the edge of a metal sheet adjacent to the die. In this pivotal moment, the stage is set for what follows. Applying reverse pressure, a shearing force comes into play, causing the material within the cutting edge to flow into the die cavity. This intricate dance occurs under three-directional compressive stress conditions, ultimately resulting in the birth of high-precision electronic stamped components.
The Manufacturing Process Unveiled
The process of crafting electronic precision stamped components can be broken down into several key stages:
1. Blueprint Creation
Everything starts with an engineering drawing of the workpiece. This blueprint serves as the foundation for what will become a complex yet elegant component. It includes three-dimensional views that provide invaluable insights into the workpiece’s dimensions, coordinate points, straight lines, curves, and cutting surfaces. Additionally, it aids in determining the workpiece’s origin coordinates and calculates coordinates for folding points and curve connection points.
2. Method Selection
Choosing the right manufacturing methods is crucial. Each surface of the workpiece has unique quality requirements, and the selection of methods must align with these demands. The precision and roughness of each surface guide the decision-making process, ultimately leading to the establishment of a precise pre-processing plan.
3. Stamping Process Design
The stamping process for the press is a critical step. It involves various operations, including hole punching, corner cutting, hole punching with blanking, embossing, tearing, and drawing. Each operation requires specialized tooling for execution. Bending processes necessitate press brakes and corresponding bending tooling. The key principle here is to prioritize operations that won’t interfere with subsequent steps, ensuring a seamless production flow.
4. Fastening Procedures
Fastening is the next milestone in the journey. Riveting processes are commonly employed and can be carried out using a press or hydraulic riveting machine. They involve attaching fasteners to the sheet metal component, using techniques such as rivet screws, rivet nuts, and rivet bolts. Thread tapping, on the other hand, enhances strength and is especially useful for thin sheet metal components. For thicker sheets, thread tapping can be performed directly without flanging.
Subsequent assembly steps bring together the various components, either through welding multiple pieces together or welding along the edges of individual components to bolster their strength. This phase is critical to achieving the desired processing outcome.
6. Surface Treatment
Finally, surface treatments add the finishing touches to the components. Options include electroplating, chromate conversion coating, painting, and oxidation, each chosen based on specific requirements and desired aesthetic qualities.
The production of electronic precision stamped components is a meticulous and multifaceted journey, demanding a blend of craftsmanship and precision. From the initial blueprint to the final surface treatment, every step plays a crucial role in crafting these high-precision marvels. By following these steps meticulously, manufacturers can ensure the creation of top-tier electronic stamped components that meet the most stringent quality standards.
