알루미늄에 대한 주의사항 스탬핑 다이스

Aluminum Plate Stamping Because aluminum alloy material is softer than metal iron, expensive, easy to break, and some aluminum alloy products require subsequent processing, such as wire drawing, anodizing, etc., the aluminum plate is particularly prone to top damage and scratches during stamping production. Therefore, special attention should be paid to the following points in the manufacture of aluminum stamping dies:

1. 프로젝트 수에 영향이 없을 경우 펀칭은 최대한 프로젝트 뒤쪽에 배치하고, 펀칭 개수가 많은 제품의 경우에도 1개의 프로젝트를 더 고려하여 펀칭을 배치합니다. 다시.
2. 알루미늄 재질은 부드럽고 금형은 재질을 차단하기 쉽기 때문에 금형의 간격을 설계할 때 양면재 두께의 10%의 간격을 두어야 합니다.
3. 굽힘 및 성형시 알루미늄 재료는 굽힘 중에 알루미늄 스크랩이 생성되기 쉽기 때문에 얼룩 및 압흔이 발생하므로 알루미늄 원료를 PE 필름으로 덮을 필요가 있습니다. 롤러 및 전기 도금의 경우 성형 블록이 연마되고 경질 도금 된 크롬이 더 좋습니다.
4. 양극 후 가공이 필요한 스탬핑 부품의 경우 평탄화 공정이 180°이면 제품을 완전히 압착할 수 없습니다. 완전한 라미네이션은 산을 뱉어내며 산이 제때에 원활하게 흘러나오도록 0.2-0.3MM 솔기를 남겨 두어야 합니다. 따라서 이 과정에서 리미트 블록을 만들어 금형보다 높게 금형을 교정해야 한다.
5. 알루미늄 재질은 깨지기 쉽고 깨지기 쉽기 때문에 특히 반대로 접을 경우 압착을 하지 않도록 합니다. 하고 싶어도 압력선을 더 넓고 얕게 만드세요.
6. 모든 알루미늄 부품은 버와 매끄럽지 않은 블랭킹을 방지하기 위해 느리게 움직이는 와이어로 절단해야 합니다. 알루미늄 부품은 고온에 취약하므로 펀치의 경도는 적어도 SKD11 재질 이상에서 60° 이상이어야 하며 D2와 같은 불량 펀치가 없어야 합니다.

Matters Needing Attention in Aluminum Plate Stamping Production

알루미늄 재질은 비교적 연질이므로 스탬핑 생산 중 상부 손상, 찌그러짐, 긁힘 및 변형이 발생하기 쉽습니다. 금형에 대한 위의 요구 사항 외에도 다음 사항을 수행해야 합니다. 스탬핑 생산:

• In order to stamp aluminum parts well and reduce the defect rate, we must first do 5S, especially cleaning: the mold, punch table, assembly line and packaging materials must be free of sharp debris, no dirt and regular clear rectification, mold up and down All must be clean and free of debris. Aluminum Plate Stamping

• It is found that the burr of the product is large, and the mold must be sent for repair in time and the result should be followed up. Aluminum Plate Stamping

• Aluminum parts are easy to heat up and become hard when they are stacked together. Therefore, when punching and blanking, it is necessary to apply some pressing oil on the material (which can not only dissipate heat, but also smooth the blanking) and then punch. Aluminum Plate Stamping

• Products with more punching holes need to be punched and the surface of the mold should be cleaned. To ensure that the molds and products are always clean and free of debris, reducing top damage. If the top damage is found, the problem point of the mold top damage must be found and solved before production can continue. Aluminum Plate Stamping

• Flattening the die push block will produce aluminum scraps, so after the push block is produced every day, the aluminum scrap under the push block must be cleaned. Aluminum Plate Stamping

알루미늄 합금 특성 및 분류

여기에서 알루미늄 합금 재료의 분석은 자동차 부품 스탬핑 산업을 예로 들어 설명합니다.

The aluminum-alloy body is mainly composed of 5 series and 6 series aluminum alloy materials. The performance characteristics of the inner panel material require good formability, high plasticity, and good connectivity. The 5 series aluminum alloy and some 6 series aluminum alloys are mainly used. For automobile outer panels, good plasticity is more conducive to forming, so 6 series aluminum alloys are widely used in outer panels according to their heat-treatable strengthening properties.

The alloys and process characteristics contained in them are shown in the table below. The most widely used grades of aluminum alloy body are: AA6016, AA6022, AA6005, AA6009, etc. Most of the 6 series is used in the outer cover; 5 series such as AA5754, AA5052 are mostly used in the inner plate. For example, Chrysler Hunter uses 6022 aluminum alloy as outer cover material, Acura NSX uses 5052 aluminum alloy as inner panel material and 6 series aluminum alloy as outer cover material.

알루미늄 플레이트 재작업 및 그라인딩 룸 설정

알루미늄 판을 재가공하고 연마하면 많은 양의 분말이 생성됩니다. 공간의 분말 농도가 높을 경우 폭발의 위험이 있습니다. 일반적으로 농도가 30g/m3에 도달하면 폭발 위험이 더 커지는 것으로 알려져 있으므로 알루미늄 판 연삭실은 방폭이 필요합니다.

• According to the characteristics of the aluminum dust itself, the dust should generally be collected in a centralized manner for pressure relief and decompression treatment. In addition, the aluminum powder grinding room needs to be isolated from the production area. Aluminum Plate Stamping
• 알루미늄 판 연삭에는 폐쇄된 연삭실과 완전한 먼지 제거 시스템이 필요합니다. 그라인딩 룸은 외부 세계와 외부 세계의 스파크 및 먼지를 격리하기 위해 연마 작업 영역에서 외부 세계를 격리하기 위해 닫히고 먼지 제거 시스템은 그라인딩 룸의 먼지 농도를 줄이기 위해 사용됩니다.
• The ventilation frequency in the grinding room is not less than 50 times/h, and the wind speed in the pipeline is not less than 20m/s. To ensure that the dust concentration in the grinding area will not reach the concentration limit and cause an explosion. Aluminum Plate Stamping
• Generally, dust explosions occur in dust collectors. When an explosion occurs, a strong shock wave will be generated. The dust in the pipeline will be raised by the shock wave and diffused. The diffused dust will be transmitted back to the factory building, which will cause a secondary explosion in the factory building. Therefore, it is necessary to add an explosion-proof isolation valve to isolate the diffusion of dust in the pipeline, and isolate the grinding work area from the explosion area. When the dust collector explodes, it should be vented to the open area outside the workshop. Aluminum Plate Stamping

알루미늄 판의 보관 및 유지 관리

Based on the active characteristics of the aluminum plate material, when storing the aluminum plate, it is necessary to pay attention to the impact of the oxidation and damage of the aluminum plate on the subsequent production and strengthen the maintenance of the aluminum plate before production to ensure the yield of the product during the production process. Aluminum Plate Stamping

• After the aluminum plate material fails and hardens, the yield strength will increase and the plasticity will decrease, which will affect the subsequent forming and hemming. It is necessary to comprehensively consider the plasticity requirements of the material during mold manufacturing. Before production, it is necessary to check whether the state of the material meets the production requirements. Aluminum Plate Stamping
• 알루미늄 판재는 포장을 푼 직후에 사용해야 합니다. 사용하기 전에 온라인으로 청소하고 기름칠을 해야 합니다. 드로잉 오일은 알루미늄 판 성형의 요구 사항을 충족해야 합니다.
• Because the aluminum plate is easy to be oxidized, it needs to be packed tightly and cannot be placed outside. The hardness of the aluminum plate is lower than that of the steel plate, so it is easy to be scratched and bruised, so special attention should be paid during handling; in addition, the outer plate parts cannot be stacked and stored, and need to be transported on a pallet, and the contact area between the bracket of the pallet and the aluminum plate should be small. , and ensure clean and soft requirements.
