Precauciones para el aluminio Estampado Muere

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. En el caso de no afectar el número de proyectos, el punzonado se debe disponer en la parte posterior del proyecto tanto como sea posible, e incluso para productos con una gran cantidad de punzones, se puede considerar un proyecto más y se debe disponer el punzonado. en la espalda.
2. El material de aluminio es suave y el molde es más fácil de bloquear el material, por lo que al diseñar el espacio del molde, se debe colocar un espacio de 10% del espesor del material bilateral.
3. Al doblar y formar, debido a que el material de aluminio es propenso a producir desechos de aluminio durante el doblado, causará daños y hendiduras, por lo que la materia prima de aluminio debe cubrirse con una película de PE. En el caso de los rodillos y la galvanoplastia, el bloque de formación se pule y el cromo endurecido es mejor.
4. Para estampar piezas que deben procesarse después del ánodo, si el proceso de aplanado y aplanado es de 180 °, el producto no se puede prensar por completo. La laminación completa producirá salpicaduras de ácido, y se debe dejar una costura de 0,2-0,3 mm para permitir que el ácido fluya sin problemas y a tiempo. Por lo tanto, en este proceso se debe realizar un bloque límite y se debe calibrar el molde más alto que el molde.
5. Debido a que el material de aluminio es quebradizo y fácil de romper, especialmente en el caso del plegado inverso, trate de no engarzarlo. Incluso si quieres hacerlo, haz que la línea de presión sea más ancha y menos profunda.
6. Se requiere que todas las piezas de aluminio se corten con alambre de movimiento lento para evitar rebabas y cortes irregulares. Las piezas de aluminio son propensas a altas temperaturas, por lo que la dureza del punzón debe ser superior a 60°, al menos con material SKD11 o superior, y no debe haber un punzón deficiente como el D2.

Matters Needing Attention in Aluminum Plate Stamping Production

El material de aluminio es relativamente suave, por lo que es fácil causar daños en la parte superior, aplastamiento, rayado y deformación durante la producción de estampado. Además de los requisitos anteriores en el molde, se deben realizar los siguientes puntos durante estampado producción:

• 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 y clasificación de la aleación de aluminio

El análisis de los materiales de aleación de aluminio aquí toma como ejemplo la industria del estampado de piezas de automóviles.

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 planificación de procesos del taller de estampado de acero y aluminio

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

Diferencia del proceso de estampado 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.

La configuración de la sala de rectificado y reprocesado de placas de aluminio

Cuando la placa de aluminio se reprocesa y pule, se generará una gran cantidad de polvo. Cuando la concentración de polvo en el espacio es alta, habrá peligro de explosión. En general, se cree que el riesgo de explosión es mayor cuando la concentración alcanza los 30 g/m3, por lo que la sala de molienda de placas de aluminio debe ser a prueba de explosiones.

• 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
• El pulido de placas de aluminio requiere una sala de pulido cerrada y un sistema completo de eliminación de polvo. La sala de molienda está cerrada para aislar el mundo exterior del área de trabajo de molienda para aislar las chispas y el polvo del mundo exterior, y el sistema de eliminación de polvo se usa para reducir la concentración de polvo en la sala de molienda.
• 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

Almacenamiento y Mantenimiento de Placas de Aluminio

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
• El material de la placa de aluminio debe utilizarse inmediatamente después de desembalar. Antes de usar, debe limpiarse y engrasarse en línea. El aceite de dibujo debe cumplir con los requisitos de formación de placas de aluminio.
• 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

En vista de la situación cada vez más común de la aplicación de estampado de placas de aluminio, de acuerdo con las características de la propia placa de aluminio, en la planificación del proceso del taller de estampado, la configuración de la línea mixta de acero y aluminio, la recolección de residuos de placas de acero y aluminio. , la configuración de la sala de rectificado y reelaboración de placas de aluminio, y el almacenamiento y mantenimiento de la placa de aluminio deben implementarse de manera integral. Teniendo en cuenta que se utiliza para mejorar la eficiencia de la producción de placas de aluminio y mejorar el diseño flexible del taller de estampado, favorece el funcionamiento razonable y eficiente del equipo del taller de estampado.
