Publish Time: 2024-08-12
In custom metal stamping design, multiple details will challenge the stamping process. Here are some of the main challenges and suggestions on how to adjust the design to ensure smooth production:
Challenges
Part shape complexity:
Challenge: Complex part shapes may lead to difficulties in mold design, increase stamping difficulty and cost.
Adjustment suggestions: Try to simplify the part shape, adopt a simple symmetrical design composed of arcs and straight lines, and avoid long cantilevers or long slots to reduce mold complexity and stress concentration during stamping.
Hole position and size design:
Challenge: The distance between holes, the distance between holes and the edge of the stamping part is too small, and the punching size is too small, which may cause the punch to break or the hole to deform.
Adjustment suggestions: Reasonably design the hole position and size, avoid too small holes and too close distances, and ensure the stability of the punching process and the life of the mold.
Material selection:
Challenge: The stamping performance of different materials varies greatly. For example, austenitic stainless steel is prone to cracking during stamping.
Adjustment suggestions: Choose the right material based on the performance requirements and cost considerations of the parts. For materials that are prone to cracking, consider using a pretreatment process or changing the material type.
Die clearance:
Challenge: Too large or too small a die clearance will have an adverse effect on the stamping quality, such as large burrs and severe die wear.
Adjustment suggestions: According to the type and thickness of the stamped material, reasonably design the die clearance to ensure the quality of the stamped parts and the life of the die.
Stamping process design:
Challenge: Unreasonable stamping process design may lead to low production efficiency, high cost and unstable quality.
Adjustment suggestions: Optimize the stamping process design, reduce processing steps, improve the utilization rate of raw materials, and ensure the stability and efficiency of the stamping process.
Suggestions for adjusting the design to ensure smooth production
Detailed analysis and simulation:
Use advanced CAD/CAM software and simulation technology to analyze and simulate the design in detail, predict possible problems in the stamping process, and make adjustments and optimizations in advance.
Close cooperation with suppliers:
Work closely with mold manufacturers and raw material suppliers to jointly solve problems encountered in the design. They have rich experience and expertise and can provide valuable advice and solutions.
Phased verification:
During the design process, verification and testing are carried out in stages. First, small batch trial production is used to verify the feasibility of the design and the stability of the stamping process, and then adjustments and optimizations are made based on the trial production results.
Continuous improvement:
During the production process, feedback and data are continuously collected to continuously improve and optimize the design. Through continuous learning and improvement, production efficiency is improved, costs are reduced, and product quality is improved.
Train employees:
Ensure that employees have sufficient skills and knowledge to operate and maintain stamping equipment. Through regular training and skill improvement activities, the skill level and operational norms of employees are improved.
In summary, multiple details in custom metal stamping design will pose challenges to the stamping process. Through detailed analysis and simulation, close cooperation with suppliers, phased verification, continuous improvement, and employee training, the design can be adjusted and smooth production can be ensured.
