Vorsichtsmaßnahmen für Aluminium Stanzen Stirbt

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. Wenn die Anzahl der Projekte nicht beeinträchtigt wird, sollte die Lochung so weit wie möglich im hinteren Teil des Projekts angeordnet werden, und selbst bei Produkten mit einer großen Anzahl von Lochungen kann ein weiteres Projekt in Betracht gezogen und die Lochung angeordnet werden im Rücken.
2. Das Aluminiummaterial ist weich und die Form kann das Material leichter blockieren, daher sollte beim Entwerfen des Spalts der Form ein Spalt von 10% der Dicke des bilateralen Materials platziert werden.
3. Da das Aluminiummaterial beim Biegen und Formen dazu neigt, Aluminiumschrott zu produzieren, führt dies zu punktuellen Beschädigungen und Einkerbungen, sodass das Aluminiumrohmaterial mit PE-Folie bedeckt werden muss. Beim Walzen und Galvanisieren ist der Formblock poliert und besser hartverchromt.
4. Bei Stanzteilen, die nach der Anode bearbeitet werden müssen, kann das Produkt bei einem Abflachungs- und Abflachungsprozess von 180° nicht vollständig gepresst werden. Eine vollständige Laminierung führt zu Säurespritzern, und es muss eine Naht von 0,2 bis 0,3 mm gelassen werden, damit die Säure reibungslos und rechtzeitig abfließen kann. Daher muss bei diesem Prozess ein Begrenzungsblock hergestellt werden und die Form muss höher als die Form kalibriert werden.
5. Da das Aluminiummaterial spröde und leicht zu brechen ist, insbesondere bei umgekehrter Faltung, versuchen Sie, kein Crimpen durchzuführen. Auch wenn Sie es möchten, machen Sie die Druckleitung breiter und flacher.
6. Alle Aluminiumteile müssen mit langsam laufendem Draht geschnitten werden, um Grate und unsauberes Stanzen zu vermeiden. Aluminiumteile sind anfällig für hohe Temperaturen, daher sollte die Härte des Stempels mindestens bei SKD11-Material oder höher über 60 ° liegen, und es sollte kein schlechter Stempel wie D2 vorhanden sein.

Matters Needing Attention in Aluminum Plate Stamping Production

Das Aluminiummaterial ist relativ weich, daher kann es während der Stanzproduktion leicht zu Beschädigungen, Quetschungen, Kratzern und Verformungen an der Oberseite kommen. Zusätzlich zu den oben genannten Anforderungen an die Form müssen die folgenden Punkte während durchgeführt werden Stanzen Produktion:

• 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

Eigenschaften und Klassifizierung von Aluminiumlegierungen

Die Analyse von Aluminiumlegierungsmaterialien nimmt hier die Automobilteile-Stanzindustrie als Beispiel.

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.

Prozessplanungsmerkmale der Stahl- und Aluminiumstanzwerkstatt

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

Unterschied zum traditionellen Stempelprozess

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.

Die Einstellung des Nachbearbeitungs- und Schleifraums für Aluminiumplatten

Wenn die Aluminiumplatte nachbearbeitet und poliert wird, wird eine große Menge Pulver erzeugt. Bei hoher Pulverkonzentration im Raum besteht Explosionsgefahr. Es wird allgemein angenommen, dass das Explosionsrisiko größer ist, wenn die Konzentration 30 g/m3 erreicht, daher muss der Schleifraum für Aluminiumplatten explosionssicher sein.

• 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
• Das Schleifen von Aluminiumplatten erfordert einen geschlossenen Schleifraum und ein komplettes Entstaubungssystem. Der Schleifraum ist geschlossen, um die Außenwelt vom Schleifarbeitsbereich zu isolieren, um Funken und Staub von der Außenwelt zu isolieren, und das Staubentfernungssystem wird verwendet, um die Staubkonzentration im Schleifraum zu reduzieren.
• 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

Lagerung und Wartung von Aluminiumplatten

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
• Das Aluminiumplattenmaterial sollte sofort nach dem Auspacken verwendet werden. Vor Gebrauch sollte es online gereinigt und geölt werden. Das Ziehöl sollte die Anforderungen der Aluminiumblechumformung erfüllen.
• 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

In Anbetracht der immer häufigeren Anwendung von Aluminiumplattenstanzen, entsprechend den Eigenschaften der Aluminiumplatte selbst, in der Prozessplanung der Stanzwerkstatt, der Stahl- und Aluminium-Mischlinieneinstellung, der Sammlung von Stahl- und Aluminiumplattenabfällen , die Einstellung des Nachbearbeitungs- und Schleifraums für Aluminiumplatten sowie die Lagerung und Wartung der Aluminiumplatte sollten umfassend implementiert werden. In Anbetracht dessen, dass es zur Verbesserung der Effizienz der Aluminiumplattenproduktion und zur Verbesserung des flexiblen Layouts der Stanzwerkstatt verwendet wird, trägt es zu einem angemessenen und effizienten Betrieb der Stanzwerkstattausrüstung bei.

Aluminum plate stamping is a metalworking process that involves using mechanical or hydraulic presses to create shapes, designs, or markings on aluminum plates. This process is commonly used in various industries, including aerospace, automotive, electronics, and manufacturing, to produce components, parts, and products made from aluminum.

Here are the key steps and considerations involved in aluminum plate stamping:

Material Selection: The first step is to choose the appropriate aluminum alloy and thickness for the specific application. Aluminum plates come in various grades and thicknesses, each suited for different purposes.

Tooling and Die Design: Tooling, including dies and punches, is designed to create the desired shape or marking on the aluminum plate. The design of the tooling is critical and should consider factors like the material’s thickness, hardness, and the complexity of the stamping operation.

Setup: The tooling is installed into a stamping press. The press can be mechanical, hydraulic, or pneumatic, depending on the requirements of the job.

Feeding the Material: The aluminum plate is fed into the stamping press, positioning it under the die and punch assembly.

Stamping Operation: The press is activated, and the die and punch come together to apply force to the aluminum plate, causing it to deform and take on the desired shape or marking. This process can involve cutting, bending, embossing, or perforating the material.

Quality Control: Throughout the stamping process, operators may inspect the stamped parts for defects, accuracy, and quality. This may involve using measuring instruments to ensure the dimensions meet specifications.

Secondary Operations: Depending on the final requirements, stamped aluminum plates may undergo additional processes such as deburring, cleaning, or surface treatment to improve appearance and functionality.

Aluminum plate stamping can be used for various applications, such as:

Creating intricate patterns and designs for decorative or aesthetic purposes.
Cutting and forming aluminum parts or components for use in automotive manufacturing.
Adding identification marks or logos onto aluminum plates.
Producing aluminum parts for the aerospace industry where precision and lightweight materials are essential.
It’s important to note that the success of aluminum plate stamping depends on factors like the quality of the tooling, the accuracy of the stamping press, and the expertise of the operators. Proper setup, maintenance, and safety precautions are crucial to achieving consistent and high-quality stamped aluminum parts.
