Precauções para alumínio Estampagem Morre

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. No caso de não afetar o número de projetos, as punções devem ser dispostas o máximo possível no verso do projeto, e mesmo para produtos com grande número de punções, pode-se considerar mais um projeto e as punções devem ser dispostas na volta.
2. O material de alumínio é macio e o molde é mais fácil de bloquear o material, portanto, ao projetar a folga do molde, deve ser colocada uma folga de 10% da espessura do material bilateral.
3. Ao dobrar e formar, porque o material de alumínio é propenso a produzir sucatas de alumínio durante a dobra, causará danos e reentrâncias no local, portanto, a matéria-prima de alumínio precisa ser coberta com filme PE. No caso de rolos e galvanoplastia, o bloco de formação é polido e o cromo duro é melhor.
4. Para estampagem de peças que precisam ser processadas após o ânodo, se o processo de achatamento e achatamento for 180°, o produto não pode ser totalmente prensado. A laminação completa produzirá salpicos de ácido, e uma costura de 0,2-0,3 mm precisa ser deixada para permitir que o ácido flua suavemente e a tempo. Portanto, neste processo, deve ser feito um bloco limite e o molde deve ser calibrado mais alto que o molde.
5. Como o material de alumínio é quebradiço e fácil de rachar, principalmente no caso de dobra reversa, tente não fazer crimpagem. Mesmo se você quiser fazer isso, faça a linha de pressão mais larga e mais rasa.
6. Todas as peças de alumínio devem ser cortadas com fio de movimento lento para evitar rebarbas e cortes não lisos. As peças de alumínio são propensas a altas temperaturas, portanto, a dureza do punção deve estar acima de 60°, pelo menos com material SKD11 ou superior, e não deve haver punção ruim, como D2.

Matters Needing Attention in Aluminum Plate Stamping Production

O material de alumínio é relativamente macio, por isso é fácil causar danos superiores, esmagamento, arranhões e deformação durante a produção de estampagem. Além dos requisitos acima no molde, os seguintes pontos devem ser feitos durante estampagem Produção:

• 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

Características e classificação da liga de alumínio

A análise de materiais de liga de alumínio aqui toma como exemplo a indústria de estampagem de peças automotivas.

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.

Características de Planejamento de Processo da Oficina de Estampagem de Aço e Alumínio

At present, most mainstream factories use steel-aluminum mixed line production, and the workshop process layout is roughly the same as that of traditional steel plate stamping workshops. According to the production characteristics of aluminum alloys and the production requirements of the workshop, its characteristics are mainly reflected in the following aspects. Aluminum Plate Stamping

Diferença do processo de estampagem tradicional

According to different material properties, aluminum alloy plates have their own characteristics in production line design, rework and grinding mold use, and application of waste collection. Table 2 shows the comparison of stamping processes between steel plates and aluminum plates. In the process planning of the aluminum alloy stamping workshop, many different factors should be combined, and the production line body should be flexibly set according to the actual steel-aluminum mixed line and the needs of the planned production capacity to meet the switching of steel and aluminum in the production process.

A configuração da sala de retrabalho e retificação de chapas de alumínio

Quando a chapa de alumínio é retrabalhada e polida, uma grande quantidade de pó será gerada. Quando a concentração de pó no espaço for alta, haverá perigo de explosão. Geralmente acredita-se que o risco de explosão é maior quando a concentração atinge 30g/m3, então a sala de moagem de chapas de alumínio precisa ser à prova de explosão.

• 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
• A retificação de chapas de alumínio requer uma sala de retificação fechada e um sistema completo de remoção de poeira. A sala de moagem é fechada para isolar o mundo exterior da área de trabalho de moagem para isolar faíscas e poeira do mundo exterior, e o sistema de remoção de poeira é usado para reduzir a concentração de poeira na sala de moagem.
• 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

Armazenamento e Manutenção de Placas de Alumínio

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
• O material da placa de alumínio deve ser usado imediatamente após a desembalagem. Antes de usar, deve ser limpo e lubrificado online. O óleo de trefilação deve atender aos requisitos de conformação de chapas de alumínio.
• 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. Aluminum Plate Stamping

Tendo em vista a situação cada vez mais comum de aplicação de estampagem de chapas de alumínio, de acordo com as características da própria chapa de alumínio, no planejamento do processo da oficina de estampagem, na configuração da linha mista de aço e alumínio, na coleta de resíduos de chapas de aço e alumínio , a configuração da sala de retrabalho e moagem da placa de alumínio e o armazenamento e manutenção da placa de alumínio devem ser implementados de forma abrangente. Considerando que é usado para melhorar a eficiência da produção de chapas de alumínio e melhorar o layout flexível da oficina de estampagem, é propício para a operação razoável e eficiente do equipamento da oficina de estampagem.
