In the realm of manufacturing dustproof mesh, blower mesh, and precision silencing mesh, the utilization of pressure processing is paramount. This technique involves employing molds mounted on a press to exert pressure on the material, leading to separation or plastic deformation. The crux of this process lies in the meticulous design of molds, which directly influences the quality of the stamped products. To achieve superior results, let’s delve into the essential aspects to consider when designing molds for these specific applications.
Strengthening the Convex Die for Blower Mesh
When designing molds for blower mesh, special attention must be devoted to reinforcing the convex die. To ensure the longevity and performance of the die, steps should be taken to address potential issues such as longitudinal bending and deformation. This can be achieved by introducing steps on the convex die or altering the material composition to enhance its strength. Additionally, it is imperative to prioritize interchangeability, aligning the convex die with industry standards wherever possible.
Precision Punching on Inclined Surfaces
When punching on inclined surfaces with an inclination angle below 15°, it is advisable to fashion the end of the convex die to be flat. However, if the angle exceeds 15°, incorporating a shearing angle at the end of the convex die becomes essential. This not only imparts rigidity but also facilitates effective cold embossing, ensuring the desired results are consistently achieved.
Leveraging Cylindrical Concave Dies
In high-speed punching operations, thermal effects may lead to variations in gaps. To counteract this, it is recommended to employ cylindrical concave dies. These dies offer the necessary rigidity and are conducive to effective cold embossing, guaranteeing precision even in the face of challenging production conditions.
Spacer Plates for Mass Production
Efficient mass production requires the inclusion of spacer plates. Simultaneous multi-hole punching demands stepped differences in the convex die design. When dealing with thick plate punching, it is imperative for the convex die to feature a shearing angle. Furthermore, proactive measures should be taken to prevent the formation of burrs. To enhance visibility during operation and mitigate blade wear, consider removing the trimming blades or base of the trimming punch die.
Edge-Finishing Multi-Hole Convex Dies
In scenarios involving deep multi-hole convex dies on the trimming punch die, it is essential to perform edge-finishing for each multi-hole convex die before overall blade utilization. This meticulous step ensures uniform and precise results in the final product. Moreover, when hole positions are in close proximity to the R part, trimming lines, or similar holes on the workpiece, it is crucial to eliminate the risk of chip jamming in the mold structure. The standard depth of entry for the convex die into the concave die should ideally range from 1 to 3mm.
Meeting Stringent Standards with Special Punching Processes
In instances where stringent requirements for hole walls and dimensional accuracy are mandated, it is imperative to explore special punching processes. These may include smooth shearing and ultra-precision punching, along with secondary finishing operations. These specialized techniques ensure that the final product meets the highest standards of quality and precision.
In conclusion, achieving excellence in the production of dustproof mesh, blower mesh, and precision silencing mesh hinges on the meticulous design of molds and the judicious application of pressure processing techniques. By adhering to the key considerations outlined above, manufacturers can optimize their processes and deliver products that stand out in terms of quality and precision in the market.
